The Model UD20 is to be used with GT3000 or PIRECL gas detectors to provide early warning of the presence of a gas mixture. Proper device installation, operation, and maintenance is required to ensure safe and effective operation. If this equipment is used in a manner not specified in this manual, safety protection may be impaired. Application The FlexVu® Model UD20 Universal Display Unit is designed to be used with the GT3000 Toxic Gas Detector or PIRECL Combustible Gas Detector. The UD20 functions as a pass through device, reading the linear 4-20 mA dc output signal from the gas detector. The detected gas concentration is indicated on an alpha-numeric display. The UD20 automatically detects the gas type and operating range of the sensor to which it is connected via the HART signal. All electronics are enclosed in an explosion-proof aluminum or stainless steel housing. The display unit is used with a single gas detector, which may be either directly coupled to the display unit, or remotely located using a sensor termination box. The UD20 features non‑intrusive calibration, which can be performed by using a handheld magnet to activate internal magnetic switches on the faceplate. Calibration can also be performed by activating the gas detector’s internal magnetic reed switch with a magnet. 4.1 © Detector Electronics Corporation 2016 Description The UD20 provides display and control capabilities for the GT3000 or PIRECL detector, and uses the following I/O: Signal Inputs: 4-20 mA loop with HART, from the gas detector User Inputs: Magnetic switches (4), on the display panel Visible Outputs: LCD display Signal Pass Through: 4-20 mA loop with HART, from the gas detector HART communication The UD20 is a HART primary master and communicates with the gas detector, which is a HART slave device. Upon power-up, the UD20 requests the gas type, measurement range, and unit of measure from the gas detector. During normal operation, the UD20 continually polls the gas detector for status information. Because the UD20 is a primary master, a secondary master can also be used to communicate with the gas detector at the same time. If an Asset Management System (AMS) is used, it should be configured as a secondary master to avoid communication conflicts with the UD20. Rev. 6/15 95-8620 magnetic switches Gas Level Indication Four internal magnetic switches provide a non‑intrusive user interface that allows adjustment of configuration parameters and calibration in the field without the use of a HART handheld device. The switches are labeled as follows: The UD20 display shows “100+” to indicate an overrange condition. For an under-range condition, the gas level indication is 0%. Actual gas level can be determined using the UD20 menu: “PROCESS VARS” > ANALOG INPUT XX.XX mA. Special States Cancel, Escape Enter, Select Special states other than normal operation and warmup require user action for activation. These include Calibration, Display / Sensor Configuration, Display / Sensor Status, and Fault indication. Refer to Appendix A (UD20 with GT3000) or Appendix B (UD20 with PIRECL) for details regarding the HART menu structure. Previous Write Protect The write protect function in the sensor can be accessed by the UD20. Next Logging The UD20 has no logging capability of its own, but reads the logs that are stored in the gas detector and displays them on the LCD screen. If an AMS is used, it communicates directly with the gas detector and not with the UD20. Device Enclosure The housing for the UD20 consists of a multi‑port aluminum or stainless steel explosion‑proof junction box with a clear viewing window. Available conduit entry sizes include 3/4” NPT and M25. UD20 Device display GT3000 or PIRECL GAS DETECTOR The UD20 is provided with a 160 x 100 dot matrix LCD display. See Figure 1. During normal operation, the UD20’s LCD display indicates the gas type and units measured. The UD20 communicates with the sensor and allows easy access to various operating parameters. Refer to Appendix A or B for details. CONTROL SYSTEM Operating and history logs that are stored in the gas detector and displayed by the UD20 include: • Calibration • Sensor running hours • Sensor temperature • Events PREVIOUS Output Test CANCEL / ESCAPE The UD20 can start and stop a 4-20 mA Loop Test for checking correct operation of system output devices. ENTER / SELECT NEXT B2426 Figure 1—Faceplate of UD20 4.1 2 95-8620 Fault Conditions When used with PIRECL faulty or incomplete configuration will render warranty and product certifications invalid. When the UD20 is connected to the PIRECL, it automatically programs the PIRECL for “User Defined Fault Mode” upon power-up and sets the following default output levels: Calibration = 3.8 mA Warm-up, General Fault, Blocked Optics = 3.0 mA CAUTION The device contains no user serviceable components. Service or repair should never be attempted by the user. Device repair should be performed only by the manufacturer or trained service personnel. This is done to ensure that the loop current stays high enough to keep the UD20 powered. The UD20 is a loop powered device and requires a minimum of 2.6 mA to operate properly. Setting the fault level to a value other than default is not recommended. Liabilities The manufacturer’s warranty for this product is void, and all liability for proper function of the Display is irrevocably transferred to the owner or operator in the event that the device is serviced or repaired by personnel not employed or authorized by Detector Electronics Corporation, or if the device is used in a manner not conforming to its intended use. If the UD20 is unable to change the mode, an “ANALOG CODE FLT” fault is annunciated. Refer to the PIRECL instruction manual, number 958526, for complete information regarding fault detection and fault modes. Caution Observe precautions for handling electrostatic sensitive devices. Zero Drift Condition Zero Drift Faults are not specifically indicated by the UD20. When the process variable drops between 3.9 and 3.1 mA, no fault is indicated by the UD20. When the process variable reaches 3.0 mA, the UD20 will display a FAULT. If a FAULT condition is indicated, the user can interrogate UD20 and PIRECL fault conditions within the UD20 menu. If no specific fault is indicated, use the menu to determine the PIRECL process variable. If that value is ≤3.9 mA, the PIRECL is experiencing zero drift and should be re-calibrated. caution Unused entries must be closed with suitably certified blanking elements upon installation. Installation note The UD20 housing must be electrically connected to earth ground. A dedicated earth ground terminal is provided on the UD20. important safety notes Install gas detectors in the appropriate locations following the guidelines below. The UD20 should be located where it can be easily viewed by personnel. The GT3000 can be attached directly to the UD20 housing, or it can be mounted remotely using a Det‑Tronics STB termination box (see the “Sensor Separation” section for additional information). The Model PIRECL should be mounted as described in the PIRECL instruction manual, number 95-8526. Detectors must always be installed per local installation practices. 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 the NEC as well as all local ordinances. If in doubt, consult the authority having jurisdiction before wiring the system. Installation must be done by a properly trained person. Always define the following application details: CAUTION This product has been tested and approved for use in hazardous areas. However, it must be properly installed and used only under the conditions specified within this manual and the specific approval certificates. Any device modification, improper installation, or use in a 4.1 Identification of vapor(s) to be detected It is necessary to always identify the vapor(s) of interest at the job site. In addition, the fire hazard properties of the vapor, such as vapor density, flashpoint, and vapor pressure should be identified and used to assist in selecting the optimum detector mounting location within the area. 3 95-8620 Device Mounting Orientation The GT3000 detector must be mounted in a vertical position only, with the sensor pointing down. See Figure 2. For details on mounting the PIRECL detector, refer to manual number 95-8526. Important The GT3000 must be oriented with the LEDs facing forward so they are easily visible to personnel within the area. To ensure correct orientation (the LEDs are not visible when power is off), position the GND lug on the left hand side and the calibration notch to the front. Note that the LEDs are located directly above the calibration notch. GND LUG GREEN LED SENSOR SEPARATION CALIBRATION NOTCH Det-Tronics sensor termination boxes (Model STBs) enable the installation of the GT3000 separately from the UD20 Universal Display Unit. Two‑conductor shielded cable is required to prevent possible nuisance EMI/RFI. B2436 Figure 2—Correct Mounting Orientation Identification of DETECTOR mounting locations The PIRECL contains its own termination box for sensor separation from the UD20. Identification of the most likely leak sources and leak accumulation areas is typically the first step in identifying the best detector mounting locations. In addition, identification of air current / wind patterns within the protected area is useful in predicting gas leak dispersion behavior. This information should be used to identify optimum sensor installation points. The maximum cable length between the termination box and the UD20 is 2000 ft. WIRING power SUPPLY requirements If the vapor of interest is lighter than air, place the sensor above the potential gas leak. Place the sensor close to the floor for gases that are heavier than air. Note that air currents may cause a gas that is slightly heavier than air to rise under some conditions. Heated gases may also exhibit the same phenomenon. Calculate the total gas detection system power consumption rate in watts from cold start-up. Select a power supply with adequate capability for the calculated load. Ensure that the selected power supply provides regulated and filtered 24 Vdc output power for the entire system. If a back-up power system is required, a float‑type battery charging system is recommended. If an existing source of 24 Vdc power is being utilized, verify that system requirements are met. The most effective number and placement of detectors varies depending on the conditions at the job site. The individual designing the installation must often rely on experience and common sense to determine the detector quantity and best locations to adequately protect the area. Note that it is typically advantageous to locate detectors where they are accessible for maintenance. Locations near excessive heat or vibration sources should be avoided if possible. NOTE The UD20 and GT3000/PIRECL communicate using HART protocol, which requires a power supply with low noise levels for proper operation. (For detailed information regarding power supply specifications, refer to the HART Communication Foundation’s document “FSK Physical Layer Specification” HCF_SPEC-54.) Final suitability of possible gas detector locations should be verified by a job site survey. For locations with expected periodic temperature conditions from –20°C to –40°C, a certified heater jacket system must be applied, and the installation should be accepted by the local authority having jurisdiction. 4.1 4 95-8620 Wiring cable requirements junction box entries, plugs, & fittings Always use proper cabling type and diameter for input power as well as output signal wiring. 22 to 14 AWG shielded stranded copper wire is recommended. Always install a properly sized, master power fuse or breaker on the system power circuit. WARNING All entries must contain appropriately rated plugs or fittings. It is required that each plug or fitting be wrench-tightened to an appropriate installation torque and meet the minimum thread engagement requirements per the applicable local standards, codes, and practices in order to retain the defined ratings. PTFE sealant or equivalent should be used on NPT threads. For ambient temperatures below –10°C, use field wiring suitable for the expected conditions. For ambient temperatures above +60°C, use field wiring and cable glands suitable for 15°C above the maximum expected conditions. Wiring Procedure note The use of shielded cable in conduit or shielded armored cable is required. In applications where the wiring is installed in conduit, dedicated conduit is recommended. Avoid low frequency, high voltage, and non-signaling conductors to prevent nuisance EMI problems. UD20 with GT3000 Refer to Figures 3 and 4 for wiring illustrations. UD20 with PIRECL No separate power lines are required for the UD20. The device can be powered off the PIRECL detector in a two-wire configuration. Figures 5 through 8 illustrate the Eclipse wired to a UD20 with the 4-20 mA output shown in various wiring schemes. caution The use of proper conduit installation techniques, breathers, glands, and seals is required to prevent water ingress and/or maintain the explosion-proof rating. A 250 ohm, 3 watt HART resistor must be installed. The current loop resistance must not exceed 440 ohms for correct functioning of the detector mA output and HART signal.

LEDs on the gas detector and messages on the UD20 faceplate guide the operator when to apply and remove the calibration gas. See Tables 1 and 2. The calibration process can be initiated using the magnetic switch on the gas detector or using the magnetic switches on the UD20 faceplate. All sensors, including oxygen, should be in clean air (20.9% oxygen) when the calibration sequence is initiated. note The UD20 allows the operator to adjust the calibration gas concentration within the range of 30 to 90% full scale. The default value for all gas sensors except oxygen is 50% full scale. Oxygen sensors use a default value of 20.9%. Once calibration is initiated, the process proceeds automatically. The yellow LED on the gas detector and the digital display on the UD20 are used to inform the operator of the progress of the calibration procedure, and also signal when to apply and when to remove the calibration gas. The calibration can be aborted after zero calibration by activating the magnetic switch on the gas detector or navigating the UD20 menu. General Calibration Information All GT3000 and PIRECL Gas Detectors provide a twopoint calibration — zero and span.

The time and date of calibration events are logged in the GT3000’s non‑volatile memory along with the calibration outcome. Possible calibration scenarios include the following: See Table 1 3.8 Calibration Procedure • Aborted Calibration 1. Clean air must be present at the sensor prior to initiating calibration. The use of bottled air is recommended. • Failed Calibration 2. Calibration can be initiated in one of two ways: • Successful Calibration A. Hold the calibration magnet against the designated location on the sensor module (see Figures 10 and 11) until the green LED turns off and the yellow LED turns on steady (approximately one second). NOTE The calibration procedure must be completed within a ten minute period. If the calibration is not completed, a calibration fault will be generated and the previous calibration data will be used. B. Initiate calibration via the magnetic switches on the UD20. Select Main Menu > Device Cal > Calibration > Execute. NOTE 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 – typically 30, 60, or 90 day intervals, depending on the ambient conditions. The UD20 indicates “Waiting for Zero.” The transmitter immediately begins taking zero readings.
