Gas concentrations are displayed on an alphanumeric display in %LFL or ppm, depending on the type of gas being detected. The transmitter provides a user selectable isolated/non-isolated 4 to 20 milliampere output signal that corresponds to the detected gas concentration. An optional relay package is available to provide contact outputs for alarm and fault conditions. The electronics of the transmitter is contained in an explosion-proof housing. The transmitter is used with a single sensor, which may be either coupled directly with the U9500 housing, or remotely located using a sensor termination box. The Infiniti offers non-intrusive calibration by actuating a magnetic reed switch with a hand-held magnet. It is not necessary to remove the housing cover to actuate the magnetic reed switch. Typical Infiniti applications include: –– –– –– Confined spaces where gas/vapor leaks can concentrate to explosive or toxic levels or where oxygen levels need to be monitored (enclosed processing areas). Known high risk leak locations (points within processing areas, compressor buildings). General open area coverage (storage areas).

Figure 1—Infiniti Transmitter Dimensions in Inches (Centimeters) DESCRIPTION Two additional options are available for resetting the transmitter. A user supplied switch can be wired to the transmitter terminal block and used to reset the device from a remote location. The U9500 is a single channel gas detection device. In addition to the standard 4-20 mA analog signal output, the U9500 offers 4 optional relay outputs for fault and alarm indications. The 4 outputs are: fault, high alarm, low alarm, and auxiliary alarm. The relays have form C (SPDT) contacts. Low, auxiliary and high alarm relay contacts are selectable as a group for latching or nonlatching operation. During normal operation, the fault relay is non-latching, but for initialization faults, the fault relay latches. The alarm relays are also selectable, as a group, for normally energized or de-energized with no alarms. The fault relay is always normally energized for no fault. In addition, Detector Electronics offers a special optional enclosure with a pushbutton pre-installed within a multiport electrical enclosure for customers who do not prefer magnetic switches. The U9500 is compatible with the entire Detector Electronics sensor family. In some cases, special personality cards are required to ensure proper operation with a specific sensor, including the DetTronics Combustible Gas sensors. The proper U9500 model must be ordered by the customer to ensure proper operation and markings for the desired sensor type. Refer to Appendix C for combustible gas sensor ATEX/CE ratings and installation details. Refer to form 90-1041 for specification details. NOTE Since the relays can be programmed to be either energized or de-energized on alarms, the term “actuate” is used to indicate that the output is in an alarm condition. Modes of operation The U9500 has three main operating modes: –– Normal –– Calibrate –– Setup (also called Configuration). Normal mode is the default mode, no buttons pushed. The U9500 provides an eight character, single line, alphanumeric LCD display. The U9500 has four switches located on the display. The visible three switches are single pole, normally open push buttons, and are designated as: Setup\accept, increase, and decrease. The fourth switch is a magnetic reed switch, designated cal/reset, which is used by the customer for non-intrusive calibrations and for resetting of the U9500. 10.1 Three minor modes also exist: –– Setpoint display –– Reset –– Power up. 3 95-8444 Important safety notes INSTALLATION WARNING Do not apply power to the system with the enclosure cover removed unless the area has been de-classified. Do not open the enclosure in a hazardous area when power is applied. WIRING REQUIREMENTS CAUTION The wiring procedures in this manual are intended to ensure proper functioning of the device under normal conditions. However, because of the many variations in wiring codes and regulations, total compliance to these ordinances cannot be guaranteed. Be certain that all wiring complies with applicable regulations that relate to the installation of electrical equipment in a hazardous area. If in doubt, consult a qualified official before wiring the system. • Install per local installation practices and in accordance with local authority having jurisdiction. • See Figures 2 and 3 for wiring size and maximum distance from the power supply to the transmitter. IMPORTANT Proper installation practices must be followed to ensure that condensation does not enter the junction box and interfere with the electronic circuitry. Refer to local installation codes. WIRING PROCEDURE The following procedure should be used for installing and wiring the Infiniti Transmitter. The Infiniti contains semiconductor devices that are susceptible to damage by electrostatic discharge. An electrostatic charge can build up on the skin and discharge when an object is touched. Therefore, use caution when handling the device, taking care not to touch the terminals or electronic components. Observe the normal precautions for handling electrostatic sensitive devices. Refer to these figures and table when installing and wiring the Infiniti: Figure 1 — Infiniti Transmitter Mounting Dimensions Figure 2 — Transmitter Wiring Requirements for Toxic and Oxygen Models with Relays Figure 3 — Transmitter Wiring Requirements for Combustible Models with Relays Figure 4 — Field Wiring Terminal with Relay Option Figure 5 — Field Wiring Terminal without Relay Option Figure 6 — Transient Suppression for Inductive Loads Table 2 — Wiring Size and Maximum Distance from Transmitter to Sensor (for applications where a sensor termination box is used) To minimize the risk of damage, handle the transmitter module by the edges only. Do not touch the circuit board, or electronic components. The fault detection circuitry does not monitor the operation of external response equipment or the external wiring to these devices. It is important that these devices be checked periodically to ensure that they are operational. TYPICAL SYSTEM WIRING Exercise caution if an over-range reading is indicated, since a dangerous condition could exist. Refer to these typical system wiring diagrams for guidance when installing and wiring the Infiniti: Figure 7 -— A Typical System, Infiniti Transmitter with a Combustible Gas Sensor, Isolated Current Output and Relay Outputs Figure 8 — A Typical System, Infiniti Transmitter with a Toxic Gas/Oxygen Sensor, NonIsolated Current Output and Relay Outputs Figure 9 — A Typical System, Infiniti Transmitter with a PointWatch Detector and Non-Isolated Current Output Figure 10 — A Typical System, Infiniti Transmitter with a PIRECL PointWatch Eclipse Detector and Non-Isolated Current Output 10.1 4 95-8444 14 AWG 16 AWG 12 AWG 18 AWG 32 32 30 30 28 28 POWER SUPPLY VOLTAGE POWER SUPPLY VOLTAGE 12 AWG 26 24 22 20 14 AWG 16 AWG 18 AWG 26 24 22 20 18 18 16 16 14 14 0 2000 4000 6000 8000 DISTANCE (FEET) 0 10000 2000 4000 6000 8000 DISTANCE (FEET) A1673 10000 A1672 Figure 2—Transmitter Wiring Requirements for Toxic and Oxygen Models with Relays Figure 3—Transmitter Wiring Requirements for Combustible Gas Model with Relays 1. Install the unit in a location that is best suited to cover the area to be protected. Whenever practical, the Infiniti should be placed where it is easily accessible for calibration. For proper operation, sensors should be pointing down, except for PointWatch, which must be mounted horizontally. See Figure 1 for mounting dimensions. 4. Connect the transmitter enclosure to the field wiring conduit. The enclosure should be electrically connected to earth ground. 5. Attach the sensor to the proper entry on the transmitter enclosure. It is recommended that a layer of teflon tape be applied to the sensor threading. Route the wires through the entry, and tighten the sensor to the enclosure to ensure an explosion-proof installation. Do not overtighten. NOTE When used with the PointWatch infrared hydrocarbon gas detector, a 1/4 inch spacer is required between the enclosure and the mounting surface to allow adequate room for the detector and calibration windshield, if required. IMPORTANT To ease maintenance, periodically apply a generous amount of Lubriplate grease (part number 102868-001) to the internal threads on the junction box cover using an application tool. Do not use any silicon based products, since some materials can cause irreversible damage to the sensing element in the gas sensor. 2. Remove the transmitter from its packing material and note the location of the field wiring terminals and (on the catalytic sensor transmitters only) the location of a small sensor connection plug on the side opposite the field wiring terminals. 6. Slide the transmitter module into the bracket, being careful to route field and sensor wires to the appropriate location within the enclosure for easy connection to the transmitter module. Ensure that the transmitter display and pushbuttons (at the top) are oriented correctly. 3. Remove the cover from the enclosure. The transmitter module slides into the mounting bracket within the enclosure and all field and sensor wiring connects to this module. –– For catalytic combustible gas transmitters, the sensor connects to a small plug on one side of the transmitter and all field wiring connects to terminals on the other side. CAUTION Wires can become pinched between the cover and base if they are not properly tucked down inside the enclosure. –– For all other gas transmitters, the sensor and field wiring all connect to the terminal block on one side of the transmitter module. 10.1 5 95-8444 External relays, solenoids, motors, or other devices that can cause inductive transients should be transient suppressed. Place a diode across the coil for dc devices. See Figure 6. 7. Fasten the transmitter module to the mounting bracket with the two captive screws located inside the notch on either side of the top of the transmitter. Remove the wire clip and set it aside. 8. See Figures 4 and 5 for field wiring terminal designation. 11. An external reset switch can be wired as shown in Figures 7, 8, 9 and 10. The use of shielded wire is recommended for wiring the switch. 9. Connect the power and current output leadwires to the screw terminals on the plug that is provided. See Figures 7, 8, 9 and 10 for examples of transmitter wiring. Connect the shield to earth ground at the power supply. The panel or field end of the shield should not be grounded at the transmitter. Contact the factory for further assistance. 12. Check all field wiring to ensure that the proper connections have been made. Refer to local codes to be sure wiring and conduit seals are installed properly. Warning When in non-latching mode, the control device must latch the alarm output. 10. For Relay models, refer to Figures 7 and 8 when connecting external loads to the relay outputs. For models without relays, proceed to step 11. CAUTION Wires can become pinched between the cover and base if they are not properly tucked down inside the enclosure. The wire clip will prevent this problem when installed correctly. IMPORTANT Direct connection of 120/240 vac to the relay terminals inside the transmitter enclosure is not permitted, since switching relay contacts can induce electrical noise into the electronic circuitry, possibly resulting in a false alarm or other system malfunction. If the application requires that ac powered equipment be controlled by the transmitter, the use of externally located relays is required.

The analog signal is capable of driving a maximum 600 ohm resistance load. Typical controllers used with the U9500 Series include the family of R8471 Controllers, or the Model 8000 eight channel controller for % LFL flammable gas monitoring. It is also acceptable to use the U9500 with other devices or systems capable of accepting 4 to 20 mA signal inputs. The following illustrations provide examples of recommended interconnecting wiring between the U9500 and analog signal receivers: Det-Tronics sensor termination boxes (STBs) enable the installation of the sensor separately from the Infiniti transmitter module. Three conductor shielded cable must be used to prevent possible nuisance EMI/RFI. Contact the factory for ordering information. (See Appendix C for CE/ATEX rating details.)

DISPLAY AND CONTROLS, OPTIONS, DEFAULTS DISPLAY AND CONTROLS Figure 17—Sensor Separation with Chlorine Gas Sensor, Intrinsically Safe Barrier and Infiniti Transmitter The Infiniti display contains an eight character display for identifying system status conditions and sensor input, a magnetic reed switch for resetting the unit and entering different operating modes, and pushbuttons for programming and calibrating the system. See Figure 18 for the location of indicators and pushbuttons and Tables 3 and 4 for descriptions. PROGRAMMING OPTIONS Operating Range The available operating range settings and the corresponding default setpoints and calibration gases are shown in Table 5. Note that not all U9500s support selectable operating range. External Reset The external reset input terminal, when grounded momentarily, normally initiates a relay/display reset only. See Figure 9. However, if the “EXT” “CAL” option is programmed “YES” during the Infiniti setup procedure, the external reset duplicates the magnetic reed switch (Cal Magnet) and can be used to perform calibration. 10.1 3 SAFE AREA – G B2310 1 IMPORTANT The range setting of the transmitter must match the output range of the sensor being used or the system will fail to operate correctly. For example, if a carbon monoxide (CO) sensor with a range of 0 to 500 ppm is being used, the range setting for the transmitter must be 0 to 500 ppm. Refer to the “Specifications” section for a listing of available sensors and ranges. 12 95-8444 Table 3—Display And Controls Display/Indicator Description This display is always on and functions as a power indicator. The display provides a continuous reading of the sensor input in both the Normal and Calibrate modes. In the event of a fault, it identifies the nature of the fault with a fault message. In other operating modes it shows the alarm setpoints and programmed calibration gas concentration. Ex %LFL / ppm A negative zero drift condition is indicated by a minus (–) sign in the left hand digit. In the event of an over-range condition, the display will continue to track the sensor output as long as the over-range condition exists. Combustible gas transmitters will latch the display at the highest detected gas concentration. * Asterisk indicates an alarm (any one) has activated since last reset. Alarm History Indicator Blank indicates no alarm has energized since last reset. Solid black square indicates that the high alarm threshold has been exceeded. n High Alarm Status Indicator For relay models, this means that the relay output has activated. Blank indicates no alarm. Solid black square indicates that the auxiliary alarm threshold has been exceeded. n Auxiliary Alarm Status Indicator n Low Alarm For relay models, this means that the relay output has activated.

For oxygen enrichment applications, use the HIGH and/or AUX alarms. *** Default settings for all Infiniti relay operation is normally de-energized with non-latching contacts (except fault alarm, which is normally energized with no faults). Default settings for optional External Reset Pushbutton is “No External Cal” enabled. Default settings for calibration mode (automatic or manual) is automatic mode. Manual calibration mode is recommended when using the U9500D chlorine or U9500F Sulfur Dioxide Transmitters. 10.1 14 95-8444 Setpoints External Calibration The Infiniti Transmitter has three independent alarm outputs (low, high and auxiliary), with field selectable setpoints. For both relay and non-relay models, these setpoints correspond to the HI, AUX, and LO ALARM indicators on the display. Calibration procedures are normally initiated and executed using the Cal Magnet to activate the CAL/ RESET switch. Choose “YES EXT CAL” during the setup procedure to allow the additional use of the external reset input terminal for initiating and executing a calibration procedure. See Figure 9 for switch wiring. Calibration Gas Concentration 4-20 Milliampere Calibration The programmed calibration gas concentration is also displayed and adjustable. This known concentration (typically one half of the instrument’s full scale detection range) of the actual gas or vapor that is expected to be detected should be used to calibrate the system. Det-Tronics calibration gas should be used to ensure proper system calibration performance and accuracy. The 4 to 20 mA current loop is factory calibrated. Perform the “YES 4-20 CAL” function in the Setup procedure if a recalibration is required. A current meter must be placed in the loop to perform this function. Calibration Current The current output during Calibration and while in the Setup mode is factory set for 2 mA. Perform the “SET CAL CURRENT” function in the Setup procedure if an output current other than 2 mA is required. IMPORTANT The calibration gas concentration setting typically matches the concentration of the gas used to perform the calibration (printed on label of calibration gas cylinder). Refer to the “Calibration” section of this manual for details. Refer to the “Setup Procedure” section for complete instructions. Latching or Non-latching Relays INFINITI SENSOR COMPATIBILITY The Low, Auxiliary and High alarm relays are programmable as a group for either latching or nonlatching operation. “LATCH” indicates that they will latch upon alarm and the unit must be reset to clear. “nonLATCH” indicates that they will automatically clear when the alarm clears. Refer to Table 6 for a list of acceptable sensor inputs to the Infiniti by model. INFINITI OUTPUTS Refer to Table 7 for a description of Infiniti standard 4 to 20 mA outputs and relay output programming options. Alarm Relays Normally Energized or Normally De-Energized MODES OF OPERATION The three alarm relays (High, Low and Auxiliary) are programmed as a group. “DE-ENERG” indicates that the three alarm relays will be normally de-energized and will energize upon alarm. “ENERG” indicates that the three alarm relays will be normally energized and will deenergize upon alarm. Refer to Table 8 for a description of Infiniti modes of operation. Automatic or Manual Calibration Manual calibration requires that the operator use the Cal magnet to activate the CAL/RESET switch, signaling an acceptance of the present calibration reading. Auto Cal is described in the “Calibration” section of this manual. 10.1 15 95-8444 Table 6—Infiniti Sensor Compatibility Infiniti Model Accepts Combustible • U9500A Accepts inputs from Det-Tronics Catalytic Combustible gas sensor only.

Table 7—Infiniti Outputs Output 4 to 20 Milliamperes (Standard) Description • The linear 4 to 20 mA output: – corresponds to the field-programmed gas range. – can be calibrated in the field for maximum accuracy. – is user selectable for isolated or non-isolated use. Refer to the “Setup ” section for programming information. 4 to 20 mA with Relays (Optional) • Option includes a set of four relays: –High Alarm –Low Alarm –Auxiliary Alarm –Fault • The High, Low and Auxiliary Alarm relays are programmable as a group for either normally energized or normally de-energized operation. • Low Alarm, Auxiliary Alarm, and High Alarm relays are programmable as a group for either latching or non-latching operation. • Fault relay is normally energized with no faults. Faults are generally non-latching, but faults that occur during calibration and warmup must be reset. • Latching relays are reset using either the Cal magnet or an external reset switch (field installed, user supplied). 10.1 16 95-8444 Table 8—Infiniti Modes of Operation Operating Mode Description • When power is applied to the transmitter, it enters a Warmup mode to allow the sensor output to stabilize before beginning normal operation. During this time the: –Fault relay is de-energized. – Alarm relays go to non-alarm state (either energized or non-energized, as programmed) – Display alternates between “WARM-UP” and “Ex” or “Toxic” or “PTIR” or “Oxygen” depending on specific model. – Current output indicates a fault condition (less than 1.0 mA). • The transmitter will stay in the Warmup mode for at least six seconds. Warmup – If the detected gas at the end of the six second warmup period is higher than the lowest alarm setting or if faults are present, the transmitter will remain in the Warmup mode until the detected gas falls below the lowest alarm setting and no faults are present, or five minutes, whichever is shortest. – If an alarm condition exists at the end of the five minute warmup, the transmitter will enter the Normal operating mode and the alarm(s) will be annunciated. – If a fault is present after the five minute warmup, the transmitter will indicate the fault, the fault relay will remain de-energized, and the current output will be less than 1.0 mA. • At the end of the warmup period with no faults or alarms present, the transmitter automatically enters the Normal operating mode (fault relay energizes, alarm relays remain in non-alarm state), and the current output will rise to 4.0 mA. • In Normal operating mode with no alarm condition: – Display is on and indicates the detected gas concentration. – Alarm relays (on relay models) are in their normal state (energized or de-energized as programmed). – 4 to 20 mA output signal level corresponds to the detected gas concentration. – Fault relay (on relay models) is energized. • In the Normal operating mode with an alarm condition occurring: – Display indicates the detected gas concentration. – Low, Auxiliary or High display shows a black square, indicating alarm condition. – Affected relay changes state (on relay models). – 4 to 20 mA output signal level corresponds to the detected gas concentration. – Fault relay output energized (on relay models). – Relay History Indicator display shows an asterisk to indicate an alarm was activated. • When the signal decreases below setpoint: Normal – Display and 4 to 20 mA output continues to track the detected gas concentration. – With latching operation programmed, numeric display shows detected gas concentration and low auxilary, or high display shows a black square indicating latched alarm output. – With non-latching operation programmed, low, auxiliary and/or high display goes blank and Alarm relay outputs return to their normal state. – Asterisk in Alarm History Indicator display stays on to indicate an alarm since last reset. • In the event of a system fault: – The normally energized Fault output is de-energized and the corresponding fault message is displayed. – 4 to 20 mA output drops to less than 1.0 mA. • In the event of an alarm condition and a system fault both occurring: – In most cases, the first condition that occurs will be indicated by the current and relay outputs and on the display. – The exceptions are “CAL ABORTED” and “SENSOR E.O.L.” faults which both may occur during the calibration procedure. If an alarm occurs with these faults, the alarm will over-ride the fault and will be indicated. 10.1 17 95-8444 Table 8—Infiniti Modes of Operation (Continued) Operating Mode Description The Reset mode is entered by holding the Cal magnet to the side of the transmitter enclosure next to CAL/RESET on the display face of the unit. Reset • Standard – When the Cal magnet is held there for less than one second, the alarm indicators turn off and all relay outputs return to their normal condition if no alarms or faults are occurring. • Forced – When the Cal magnet is held there for 1 to 2 seconds, the alarm indicators turn off and the relay outputs return to their normal condition even if an alarm or fault condition still exists. • Remote – Activating the remote reset switch for less than 2 seconds initiates a forced reset. If “YES EXT CAL” was selected during the setup procedure, the external reset input initiates the setpoint display cycle when activated for over two seconds. When the Cal magnet is held to the side of the transmitter enclosure next to CAL/RESET for more than two seconds, the transmitter enters the Setpoint Display mode. Once in this mode, the Cal magnet can be removed. The Setpoint Display sequence will complete automatically. (The external reset input terminal can also be used to initiate the setpoint display and calibration mode if “YES EXT CAL” was selected during the setup procedure.) In this mode: • The display sequentially shows the programmed alarm setpoints and calibration gas concentration. • Each value is displayed for approximately 1.5 seconds. Setpoint Display • After completing the sequence, the transmitter automatically returns to the Normal operating mode if the Cal magnet is no longer being held to the unit (or the external reset input is not activated). NOTE If the CAL/RESET switch (or external reset input) is still activated at the end of this cycle, the transmitter automatically enters the Calibrate mode. If a calibration is not performed, a CAL ABORTED fault will occur. To exit the Calibrate mode without performing the calibration, cycle power or wait for the calibration fault message, then reset the unit. The Setpoint Display mode is used only for displaying the setpoints. Use the “Setup” mode for changing setpoint and calibration gas values. Auto calibration is the default setting and the recommended calibration method for all sensors except for Chlorine (Cl2) and Sulfur Dioxide (SO2). Auto calibration is required for use with PointWatch. • Auto Cal is an automatic calibration procedure that requires no adjustments by the operator. The Calibrate mode is entered by holding the Cal magnet to the CAL/RESET magnetic switch until completion of the “Setpoint Display” sequence described above (approximately 7 seconds). (The external reset input terminal can also be used to enter the calibrate mode if “YES EXT CAL” was selected during the Setup procedure. Activate the input until completion of the “Setpoint Display” sequence.) • For calibration of the Infiniti with the C7065E O2 sensor, there are two modes of Auto Calibration available: 1. Initial / Sensor Replacement Calibration 2. Routine Calibration Use Option #1 for new sensor start-up or after replacing a sensor. Use Option #2 for all subsequent calibrations after Option #1 has been completed. Auto Calibration • The transmitter performs the Zero adjustments, then signals the operator when to apply and also when to remove the calibration gas. Upon completion of a successful calibration, the transmitter automatically returns to the Normal operating mode. • If the operator fails to complete the calibration procedure, if an error in calibrating occurs, or if a successful calibration cannot be completed, the transmitter will automatically return to the Normal mode and continue to use the previous calibration data (after 10 minutes or when the gas level drops below the lowest alarm setpoint). A fault indication will be displayed until a reset occurs. • If the microprocessor determines that the sensor cell is approaching the end of its useful life, the message “SEN AT EOL” will be indicated on the display. A fault indication will be displayed until a reset occurs. • While in the Calibrate mode, all transmitter outputs are inhibited and the dc current output goes to a preset level (adjustable from 0 to 20 mA, with a default value of 2.0 mA). See “Setup” section for complete calibration procedure. 10.1 18 95-8444 Table 8—Infiniti Modes of Operation (Continued) Operating Mode Description Manual Calibration Use the manual calibration mode when calibrating the Chlorine (Cl2) and Sulfur Dioxide (SO2) sensors. • Manual Calibration must be selected during the initial set up of Infiniti. • Manual calibration is similar to Auto Calibration, except that when the Zero and Span (calibration gas concentration) readings are displayed and judged stable by the operator, they must be manually accepted as calibration points by holding the Cal magnet to the CAL/RESET magnetic switch (or activate the external reset input if “YES EXT CAL” was selected during the Setup procedure.) Setup In the setup mode, the range (for some gases), alarm setpoints, calibration gas level, current loop levels, relay operation (latching/non-latching, energized/de-energized), and calibration mode (auto/manual) are programmed into the transmitter. NOTE When used with PointWatch only 50% LFL gas may be used for span concentration. PointWatch will not read accurately if other concentrations are used. INSTALLATION CHECKLIST STARTUP PROCEDURE The following checklist is provided as a means of checking the system to be sure that all phases of system installation are complete and have been performed correctly. 1. Remove power from all output devices to prevent actuation. 2. Apply power to the system. If the proper “type of sensor” indication does not appear in the display during warmup, consult the factory. 1. Enclosure is securely mounted and sensor is pointing down. (PointWatch models must be mounted horizontally. Refer to the PointWatch manual for details.) 3. When the Warmup period is completed, perform the Setup procedure. 4. Perform the Calibration procedure. 2. Ensure that local wiring and installation codes are met. 5. Restore power to the output devices. 3. Power wiring is installed and power source is operational. SETPOINT DISPLAY MODE 4. Wiring to external loads and/or monitoring devices is properly connected. In this mode, the display sequentially shows the programmed alarm setpoints and calibration gas concentration, then returns to the Normal operating mode (see Table 9). Remove power from all output devices to prevent actuation. 5. If a sensor termination box is used, shielded interconnecting wiring is correctly installed. 6. All cable shields are properly connected. 7. Optional sensor accessories (dust/splash guards, sample draw devices, etc.) are installed, clean, and in good condition. 8. O-ring is in good condition and the junction box cover is tightly installed. 9. Monitoring devices and/or response equipment is operational. 10.1 19 95-8444 Table 9—Setpoint Display Cycle Display Indicates Duration and Description Normal Mode To enter the Setpoint Display mode, activate the CAL/RESET magnetic switch for 2 to 3 seconds (hold the Cal magnet to the side of the transmitter enclosure next to CAL/RESET). If “YES EXT CAL” was selected during the “Setup Procedure,” the external reset input can also be used to initiate the Setpoint Display Cycle when activated for 2 to 3 seconds. Low Alarm Setpoint 1.5 seconds High Alarm Setpoint 1.5 seconds Auxiliary Alarm Setpoint 1.5 seconds 1.5 seconds IMPORTANT For catalytic sensors only, whenever the type of calibration gas that is used differs from the gases to be detected, a Conversion K - Factor must be applied to ensure proper operation. Refer to “Catalytic Sensor Calibration” section in this manual for details. Calibration Gas Concentration Normal Mode Remains in Normal mode until another mode is activated. SETUP PROCEDURE 3. Press and hold the SETUP/ACCEPT button for 1 second using a small screwdriver, then release. This initiates the Infiniti Setup Mode. Refer to Table 10 to perform setup. Once a programming option has been accepted, the transmitter will automatically cycle to the next option. 1. Determine the required alarm setpoint levels, calibration gas concentration, and other settings such as range (Table 5), auto/man calibration, normally energized/de-energized relays, latching/ non-latching relays. CALIBRATION CAUTION Changing the range selection will cause the alarm setpoints and the calibration gas settings to default to the setting shown in Table 5. Catalytic combustible, PointWatch infrared, and oxygen sensors have preset ranges that are automatically selected by the Infiniti and cannot be changed. CALIBRATION RECOMMENDATIONS The Infiniti can accommodate automatic or manual calibration and for many sensors either of these methods are effective. Certain sensors, however, require either automatic or manual calibration only. The sensors and method of calibration required and/or recommended are listed in Table 11. Refer to this table before proceeding with calibration. 2. Remove the enclosure cover to access the transmitter display and controls. Perform Calibration CAUTION While in the Setup Mode, the current loop output will drop to less than 1 mA. For models without relays, this is the only remote indication that the unit is not in the Normal operating mode. For models with relays, the fault relay indicates a fault. In either case, the transmitter will remain in the Setup mode until Setup is complete. The transmitter must be manually stepped through the sequence below in order to return to the Normal operating mode. 10.1 20 • When a new system is initially put into service. • When the sensor is replaced. • Periodically to verify proper performance for combustible, toxic and oxygen detectors - typically at 90 day intervals, however, this frequency is dependent upon the requirements of each application. Refer to the PointWatch manual for calibration recommendations specific to that device. Refer to Table 12 for the recommended calibration frequency for sensors manufactured by Det-Tronics. 95-8444 Table 10—Infiniti Setup Display Left portion displays the present range setting.

The calibration gas concentration should be one half of the full scale measurement range of the sensor in use. Table 11—Recommended Sensor Calibration Methods Calibration Method Sensor Auto Combustible Catalytic (Ex) X H2S X CO X PointWatch (HC) X only O2 X only Manual Cl2 X only SO2 X only For oxygen sensor calibration, normal ambient air may be used for span calibration if it is known to be clean and not depleted of O2 (21% vol.). Compressed clean air is available from Det-Tronics if required. It is not necessary to utilize an O2 free gas such as compressed nitrogen to calibrate the O2 sensor zero level. An electronic zero switch is provided within the C7065E sensor housing for this function. Refer to the O2 sensor instruction manual for details. Important Calibration Notes Calibration Gas Sources For optimum performance, calibration gases. only use Det-Tronics IMPORTANT The calibration gas concentration setting must match the concentration of the gas used to perform the calibration (printed on label of calibration gas cylinder). For PointWatch calibration, use only 50% LFL concentration calibration gas of the same type as selected by the PointWatch gas selection switch. Refer to the PointWatch instruction manual for details. • Ensure that the transmitter is properly programmed for the gas concentration being used for calibration. (See the “Setup” section.) • Ensure that only clean air is present at the sensor prior to entering the calibration mode. If the possibility of background gases exists, purge the sensor with clean air to ensure accurate calibration. • Ensure that the concentration of the calibration gas matches the calibration gas setting. Typically, calibration gas concentration equal to 50% full scale is used. • If the calibration procedure is not completed or if the sensitivity of the sensor has deteriorated to the extent that calibration cannot be successfully completed, a fault will be generated and the system will automatically revert back to the former calibration settings (after 10 minutes or when the gas level drops below the lowest setpoint). If a successful calibration cannot be accomplished, replace the sensor and the hydrophobic filter (if used) and re-calibrate. For catalytic sensor calibration, most applications require the use of 50% LFL calibration gas matching the type of gas to be detected. If a matching calibration gas type is not available, a conversion K-factor must be used. Refer to the “Catalytic Sensor Calibration” section in this manual for details.

Must be calibrated if gas selection setting other than methane is used. 10.1 23 95-8444 • Inspect the sensor. Loss of sensitivity can be caused by various factors. One common cause is by clogging of the hydrophobic or sintered filters by dirt, oil, paint, etc. Problems of this nature will not be detected by the transmitter’s diagnostic circuitry when used with catalytic or electrochemical sensors. If the filter or the sensor are dirty or plugged, they should be replaced. When the transmitter is used with the PointWatch Infrared detector, contamination of its optical surfaces will be annunciated. • When calibrating a C7065E O2 Sensor, the initial “zero” calibration requires activation of a switch located inside the sensor housing. Subsequent calibrations of the sensor do not require switch activation. Always calibrate the sensor using 20.9% O2 if ambient air is less than 20.9% O2. A conversion K-factor must be used in the calibration of the system whenever detection of gases/vapors other than the gas used in the actual calibration process will occur. Refer to the “Det-Tronics K-factor Tech Note” for the current list of Det-Tronics K-factors. The K-factor represents the relative sensor response ratio of the calibration gas to the detected gas. The K-factor is used within the “K-factor equation” to determine the proper transmitter output level (span setpoint) when the sensor is exposed to the calibration gas. The K-factor equation is as follows: CxK=S AUTO CALIBRATION PROCEDURE In the Auto Cal mode, all adjustments are made automatically by the transmitter once calibration has been initiated. Auto Cal mode is recommended for all sensors except Cl2 and SO2. Refer to Table 13 for the Automatic Calibration Procedure. Concentration of the calibration gas in % LFL K = Conversion K-factor for the gas to be monitored with the given calibration gas S = Corrected combustible gas transmitter calibration span output level (span setpoint) Example: Gas to be detected: Propane Calibration gas: 50% LFL Methane in air K-factor: 1.39 Equation: O2 Sensor Calibration Initial calibration of the U9500C/C7065E O2 detector requires removal of the C7065E sensor housing for access to the zero selection switch. Subsequent calibrations of the sensor will not require removal of the sensor housing, nor nitrogen purging. The U9500C will automatically set the zero cal level even with normal levels of O2 displayed during the zero calibration process. Refer to “Calibration Procedure for Infiniti with C7065E Oxygen Sensor” for details. C x K = S 50 x 1.39 = 69.5 For proper system sensitivity to propane, the Infiniti transmitter calibration gas concentration setpoint should be adjusted to read 69% LFL. When the sensor is calibrated with 50% LFL methane in air calibration gas mixture, the sensor will provide an accurate measurement of propane. If more than one calibration gas type and K-factor is listed for a gas that will be detected, generally the best calibration gas to use is that which provides a K-factor closest to the value of 1.0 (one). Note that the presence of Methane gas as a potential detectable gas is an exception. Always use Methane calibration gas if Methane is expected to be present within the protected area. Catalytic Sensor Calibration Catalytic sensors respond to many combustible gases. While it is highly recommended that a sensor be calibrated to detect a single gas, the fact remains that only a few calibration gas types are available. In addition, multiple gas hazards may exist. If a specific gas/vapor and K-factor is not listed within the “Det-Tronics K-factor Tech Note”, a K-factor can be determined by Det-Tronics Sensor Engineering department. Contact the factory for details. A known concentration (typically one half of the full scale detection range of the instrument) of the actual gas or vapor type that is expected to be detected should be used to calibrate the system. Det-Tronics calibration gas should always be used to ensure proper system calibration performance and accuracy. Calibration gas should not be used if the Oxygen concentration within the gas is listed at less than 20% by volume. 10.1 C = 24 95-8444 Table 13—Automatic Calibration Procedure Description Display Operator Action Normal operation/no gas present Indicates the detected gas concentration • If the possibility of background gases exists, purge the sensor with clean air to ensure accurate calibration.

For best results, allow the U9500/C7065E to warm up for one hour before performing the calibration procedure. MANUAL CALIBRATION PROCEDURE In the Manual Cal mode, the CAL/RESET switch must be activated using the Cal magnet to accept a reading as a calibration point. (The external reset input can also be used to accept a reading if “YES EXT CAL” was selected during the Setup procedure.) Initial/Replacement Sensor Calibration Procedure 1. Remove the C7065E aluminum sensor cover. Leave the sensor cell plugged in. The Infiniti must be programmed for manual calibration prior to initiating the manual calibration procedure (refer to the Setup section). Refer to Table 14 for the Manual Calibration Procedure. 2. Apply the calibration magnet to the U9500 calibration target location for nine seconds, or until the U9500 display shows “zero-cal”. 3. Move the toggle switch on the electrochemical sensor cell to the “zero” position. See Figure 19 for switch location. This will simulate the “zero” or “nooxygen” condition necessary to establish a baseline output calibration level. When the U9500 display reads “00”, move the toggle switch back to the “on” position. Place the aluminum sensor cover over the cell and reinstall. IMPORTANT The Manual Calibration Procedure must be used for chlorine (Cl2) and sulfur dioxide (SO2) sensors. Use the Auto Calibration Procedure for all other sensors. Calibration Procedure for Infiniti with C7065E Oxygen Sensor There are two calibration procedures for the U9500/ C7065E: 1. Initial/Replacement Sensor Calibration. This procedure should be used on new product initial calibration, or any time an existing sensor has been replaced with a new or different sensor. This procedure requires removal of the sensor housing. Live DC circuits will be exposed to the surrounding environment during this procedure. ZERO SWITCH 2. Routine Calibration. This procedure should be used for subsequent calibrations after the initial/ replacement sensor calibration procedure has been performed. This procedure does not require removal of the sensor housing, and no live circuits will be exposed. A1472 Figure 19—Electrochemical O2 Sensor Cell 4. When the U9500 display shows “aply-gas”, the transmitter will begin to record the sensor output level in response to the ambient oxygen concentration. If this is known to be 20.9%, an accurate span calculation will result. If the ambient O2 level is less than 20.9%, it is recommended to apply 20.9% oxygen using a Det-Tronics O2 calibration kit. Before performing either procedure: 1. Ensure that the device is properly installed and wired. 2. Ensure that the electrochemical cell is installed properly. 3. Ensure that the U9500/C7065E is powered-up and displays normal operating mode without fault indication. In not, clear all faults before attempting to enter calibration mode. 5. When span calculations are complete, the U9500 display will indicate “cal-OK”, and then “rmv-gas”. If using a Det-Tronics O2 calibration kit, remove the calibration cup and close the regulator valve. No actions are necessary if ambient air O2 is used. 4. Ensure that the U9500/C7065E has been programmed for “auto calibration” mode. Manual calibration mode is not compatible with the C7065E sensor. 6. The U9500 will automatically exit calibration mode when calibration is complete. The displayed O2 level should be 20.9% (17.4 mA current level) if ambient conditions are normal. 10.1 26 95-8444 5. While the Infiniti transmitter display is indicating “Zero Drift,” simultaneously press and release the Increase and Decrease switches on the Infiniti faceplate. The Infiniti will exit the warm up mode and display an incorrect gas level reading. Routine Calibration Procedure 1. Do not remove the C7065E sensor cover. 2. Apply the calibration magnet to the U9500 calibration target location for nine seconds, or until the U9500 display shows “zero-cal”. The initial zero baseline output level reading will be referenced. Wait until the U9500 display shows “aply-gas”. 6. Calibrate the U9500A following the “Initial/ Replacement Sensor Calibration” procedure. 7. Replace the Infiniti J-box cover. 3. The transmitter will now begin to record the sensor output level in response to the ambient oxygen concentration. If this is known to be 20.9%, an accurate span calculation will result. If the ambient O2 level is less than 20.9%, it is recommended to apply 20.9% oxygen using a Det-Tronics O2 calibration kit. 8. Re-enable any alarming devices triggered by the U9500A Infiniti alarm outputs. Alternate method: This method can be used in a classified/hazardous area. 1. Disable any alarming devices triggered by the U9500A Infiniti transmitter alarm outputs. 4. When span calculations are complete, the U9500 display will indicate “cal-OK”, and then “rmv-gas”. If using a Det-Tronics O2 calibration kit, remove the calibration cup and close the regulator valve. No actions are necessary if ambient air O2 is used. 2. Power up the U9500A with a new or different CGS sensor installed. 3. Wait for the U9500A Infiniti transmitter to display “Zero Drift” indication (approximately 4 minutes from power up). 5. The U9500 will automatically exit calibration mode when calibration is complete. The displayed O2 level should be 20.9% (17.4 mA current level) if ambient conditions are normal. 4. Apply calibration gas to the sensor. After approximately 30 seconds, the U9500A will reset, go through the startup cycle, and display some incorrect gas level. cgs sensor replacement Under certain circumstances, an existing U9500A Infiniti gas transmitter fitted with a replacement CGS sensor may not exit “warm up” mode after four minutes from power up, causing a “Zero Drift” indication to be displayed on the U9500A. This uncommon situation can occur when a CGS pellistor resistance is slightly offset from the previous CGS pellistor resistance. It does not mean that the sensor or the Infiniti transmitter are bad or out of tolerance. 5. Apply a calibration magnet and hold it in place until the Infiniti transmitter enters the calibration mode. The Infiniti display will read a gas indication number alternating with “Zero Cal”. 6. Remove the calibration gas from the sensor. 7. Allow the Infiniti to zero calibrate to the new or different sensor. 8. When prompted by the Infiniti, apply the calibration gas to set the 50% LFL span setting. There are two simple methods to solve this problem. 9. Once the Infiniti accepts the new span setting, follow the prompts to exit the calibration mode. Preferred method: 10. From this point, allow the sensor to fully warm up for one hour minimum, and then calibrate the U9500A following the normal calibration procedure in the instruction manual. This method requires a Hot Work Permit and declassification of the work area. 1. Disable any alarming devices triggered by the U9500A Infiniti transmitter alarm outputs. 11. Re-enable any alarming devices triggered by the U9500A Infiniti alarm outputs. 2. Power up the U9500A with a new or different CGS sensor installed. Contact the factory if you have any questions or comments. 3. Wait for the U9500A Infiniti transmitter to display “Zero Drift” indication (approximately 4 minutes from power up). 4. Remove the cover from the Infiniti transmitter. 10.1 27 95-8444 Table 14—Manual Calibration Procedure Description Normal operation/no gas present Display Operator Action • Ensure that the unit is set for Manual Calibration.

See Table 15 - Fault Messages, Explanations “RMV” and Corrective Action. “GAS” 28 95-8444 TROUBLESHOOTING Prioritized Faults The faults are prioritized, with the highest fault being the only one displayed (see Table 15 for a prioritized listing). If an additional fault exists, it will be displayed after the higher priority fault has been cleared. Automatic Diagnostics and Fault Messages The transmitter features self-testing circuitry that continuously checks for problems that could prevent proper system response. When power is applied, the microprocessor automatically tests the unit. If a fault is detected during this warmup mode, it will be indicated on the display and must be reset to clear. In the Normal operating mode, it continuously monitors the input signal from the sensor to ensure proper functioning. Clearing Faults Generally, faults that occur while in the normal mode are self-clearing once the fault condition has been corrected. Faults that occur while in the warmup and calibration modes require a manual reset to clear (using either an externally connected reset switch or the Cal magnet). After the fault condition has been corrected, the fault relay automatically switches to the normal (energized) state, the dc current output returns to normal, and the fault message turns off. In the event of a system fault: • The display identifies the nature of the fault using a fault message. Refer to Table 15 for an expanded explanation of the messages. • The normally energized Fault relay (on relay models) is de-energized. • The dc current output drops to less than 1.0 mA. CAUTION The fault detection circuitry does not monitor the operation of external response equipment or the wiring to these devices. It is important that these devices be checked periodically to ensure that they are operational. NOTE The fault message will be shown for about 1.5 seconds out of every 3 seconds. The gas concentration at the sensor will be displayed during the remaining time. If more than one fault should occur, the highest priority fault will be displayed. (Table 15 lists the faults in order of priority.) In the event of an alarm condition and a system fault both occurring: • In most cases, the first condition that occurs will be indicated by the current and relay outputs and on the display. • The exceptions are “CAL ABORTED” and “SENSOR E.O.L.” faults, which both can occur during the calibration procedure. If an alarm occurs with these faults, the alarm will over-ride the fault and will be indicated. 10.1 29 95-8444 Table 15—Fault Messages, Explanations And Corrective Action Fault Message Display Blank Display EEPROM sumcheck failure.

It does not monitor external response equipment or the wiring to these devices. It is important that these devices be checked initially when the system is installed, as well as periodically during the ongoing maintenance program. • The system must be checked periodically in the Normal mode to ensure that those items not checked by the transmitter diagnostic circuitry (such as output relays) are functioning properly. Gases and/or vapors that can cause permanent loss of sensor sensitivity: –– Silicone compounds often found in oils, greases and resins. –– Antiknock compounds such as tetra ethyl lead, tetra methyl lead and phosphate esters. Gases and/or vapors that can cause inhibition (temporary loss of sensitivity) of the sensing element: SENSOR AND HYDROPHOBIC FILTER REPLACEMENT –– Volatile halogenated compounds. –– Tetrachloroethylene. CAUTION Be sure to secure all output devices that are actuated by the system to prevent unwanted activation of this equipment, and remember to place these same output devices back into service when the checkout is complete. –– Fluorinated hydrocarbon. –– Vapors that result from hot P.V.C. –– Acids and various solvents may cause a shift in the zero of electrochemical sensor. –– Chlorine and Chlorinated HC. Catalytic Sensor Replacement NOTE The sensor must be periodically inspected and calibrated following prolonged exposure to contaminating gases and vapors. For catalytic combustible gas sensors, it is necessary to replace the entire sensor assembly when it is defective. Follow the procedure below to replace the sensor. 1. Remove power to the transmitter prior to replacing the sensor. MAINTENANCE 2. Remove the transmitter cover and the wire shield within the transmitter. If a sensor termination box was used, remove the sensor junction box cover. CAUTION Be sure to secure all output devices that are actuated by the system to prevent unwanted activation of this equipment, and remember to place these same output devices back into service when the checkout is complete. • • 10.1 3. Unplug the sensor from the transmitter module (if a sensor termination box was used, unplug it from the plug inside the termination box) and unscrew it from the conduit entry. 4. Thread the wires for the replacement sensor through the conduit entry, then screw the sensor into the conduit entry and plug it in. Replace the wire shield. Periodically apply a generous amount of Lubriplate grease (part number 102868-001) to the internal threads on the junction box cover using an application tool. DO NOT use other lubricants, since some materials can cause irreversible damage to the sensing element in the gas sensor. 5. Replace the junction box cover. 6. Re-apply power. Allow time for the unit to warm up and stabilize (approximately 24 hours for best results), then calibrate. To ensure reliable protection, it is important to check and calibrate the detection system on a regularly scheduled basis. The frequency of these checks is determined by the requirements of the particular installation - 90 days is typical. 31 95-8444 Electrochemical Sensor Cell Replacement NOTE Handle the sensor cell carefully. To avoid possible damage, observe the normally accepted procedures for handling electrostatic sensitive devices. See form 75-1005 for additional information. For sensors with replaceable sensor cells (toxic and oxygen sensors), it may not be necessary to replace the entire sensor housing assembly when the sensor is defective. Follow the procedure below to replace the sensor cell. 1. Remove power to the transmitter prior to replacing the sensor cell. 5. Be sure that the O-ring on the sensor housing is in good condition, then place the cap back on the sensor base. Tighten only until snug. Do not over tighten. 2. Remove the cap from the sensor base. See Figure 20. (There is no need to remove the sensor housing from the junction box for this operation). 6. Re-apply power. Allow time for the unit to warm up and stabilize (approximately one hour for best results), then calibrate. NOTE Compare part numbers to be sure that the correct replacement cell is being used. An adequate supply of spare electrochemical cell assemblies should be kept on hand for field replacement. For maximum protection against contamination and deterioration, they should not be removed from the original protective packaging until the time of installation. To ensure maximum storage life, electrochemical cells should be stored in the unopened bag that the sensor is shipped in, at a temperature between 32°F and 68°F (0 to 20°C) and a relative humidity between 15 and 90 percent. 3. Remove the old sensor cell. The sensor cell contains a small amount of lead – dispose of properly. Check for corrosion or contamination on the terminals of the sensor base, and clean if necessary. 4. Determine proper orientation for the new cell, then carefully plug it in. SENSOR HOUSING SENSING ELEMENT ASSEMBLY CAP HYDROPHOBIC FILTER NOTE: SENSOR APPEARANCE MAY VARY SLIGHTLY DEPENDING UPON MODEL. B1203 Figure 20—Electrochemical Sensor Parts Identification 10.1 32 95-8444 DEVICE REPAIR AND RETURN Hydrophobic Filter Replacement The hydrophobic filter on the front of some of the electrochemical sensor housings protects the sensor cell from contaminants in the environment, and also enables the operation of the cell in “wet” environments without plugging its screen. The operator should frequently inspect the hydrophobic filter for cleanliness. A dirty filter can significantly reduce the amount of gas that is able to reach the sensor cell, thereby impairing the ability of the system to respond to a hazardous condition. If the filter becomes dirty or if it is damaged, it must be replaced. Prior to returning devices, contact the nearest local Detector Electronics office so that a Service Order number can be assigned. A written statement describing the malfunction must accompany the returned device to expedite finding the cause of the failure. Pack the unit properly. Use sufficient packing material in addition to an antistatic bag or aluminum-backed cardboard as protection from electrostatic discharge. Return all equipment transportation prepaid to the factory in Minneapolis. To replace the hydrophobic filter, simply unscrew the existing filter from the housing, then replace it with a new filter. Use care not to over tighten. NOTE A dirty hydrophobic filter can adversely affect the response of the sensor by blocking the flow of gas to the sensor cell. If the detector cannot be calibrated or responds slowly to the calibration gas, check the condition of the hydrophobic filter before replacing the sensor cell. The hydrophobic filter should be clean and squarely seated in the housing.
