When a pressurized gas leak occurs, the frequency content of the sound being generated extends beyond the audible portion of the spectrum into the ultrasonic region (above 20 kHz). The intensity of the sound generated by a leak is determined by several factors including pressure, leak rate, gas viscosity, and distance from the leak source. Acoustic detection is less susceptible to environmental factors (such as high winds) that can degrade the ability of traditional sensing technology based on gas concentration to detect the presence of a leak. When combined with line of sight and/or point gas detectors, the additional layer of protection provided by the FlexSonic Acoustic Detector offers the ultimate solution for gas leak detection.

The FlexSonic Acoustic Detector is comprised of two main components: the AC100 Acoustic Sensor, and the ATX10 Acoustic Transmitter. AC100 The AC100 Acoustic Sensor detects events such as gas leaks by looking for changes in the spectrum of the received acoustic signal. To do this, the AC100 employs a high performance microphone and digital signal processing (DSP) technology to continuously monitor the acoustic signal. Maximum Loop Resistance— 300 ohms at 18 Vdc; 600 ohms at 24 Vdc. Wiring terminals— Rated for 14 to 18 AWG (2.5 to 0.75 mm2) wire. The wide dynamic range and spectral resolution enable the sensor to provide both superior sensitivity and false alarm discrimination.

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 sufficient regulated and filtered 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 power is being used, verify that system requirements are met. External Bonding (AC100 and atx10) Per ATEX/IECEx requirements, 4 mm2 wire shall be attached to external ground connection. Shield Connections note The power supply must meet the noise requirements for HART systems. If noise or ripple on the main power source could interfere with the HART function, an isolated power source is recommended. (For detailed information regarding power supply specifications, refer to the HART Communication Foundation’s document “FSK Physical Layer Specification” HCF_SPEC-54.) The ATX10 provides terminals for proper grounding of wiring cable shields. These shield terminals are not connected internally, but are connected to ground through capacitors. The capacitors ensure an RF ground, while preventing 50/60 Hz ground loops. Ground all shields as shown in the wiring examples throughout this manual. Wiring cable requirements important For proper grounding, all junction boxes / metal enclosures must be connected to earth ground. Always use proper temperature rated cabling type and diameter for input power as well as output signal wiring. 14 to 18 AWG shielded stranded copper wire is recommended. The following are required for installations requiring CE Mark compliance: • For shielded cable installed in conduit, attach the wire shields to the “shield” connections on the terminal blocks, or to earth ground on the case. The field wiring terminal connections are certified for a single wire in size from 0.2 to 2.5 mm2 (or two conductors with same cross section 0.2 to 0.75 mm2). The screws must be tightened down with a torque 0.4 to 0.5 Nm. The metal housing must be electrically connected to earth ground. • For installations without conduit, use double shielded cable. Terminate the outer shield to earth ground on the case. Terminate the inner shield to the “shield” connection on the terminal blocks. A minimum of 9 Vdc must be present at the ATX10 to ensure proper operation. The maximum cable length from power source to ATX10 is 2000 feet. When the AC100 Sensor is mounted remotely using an STB termination box, maximum cable length from ATX10 to AC100 is 500 feet. Sensor installation 3/4” NPT Models 3/4” NPT models have tapered threads and a connector assembly. Install the sensor as follows: note The AC100 has an Intrinsic Safety (IS) Barrier. Proper NEC/CEC IS grounding must be ensured. 1. Screw the sensor into the appropriate entry on the termination box. Ensure a minimum of 5 fully engaged threads. Use of Teflon tape on NPT threads is recommended to prevent thread damage. note 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. 2.5 2. When the sensor gets tight, note the position of the set screw on the sensor housing. It should be oriented away from the mounting surface to ensure adequate clearance between the sensor and mounting surface. See Figure 8. 14 95-8657 ORIENT SET SCREW AWAY FROM MOUNTING SURFACE TO ENSURE ADEQUATE CLEARANCE BETWEEN SENSOR AND SURFACE A2618 Figure 8—AC100 Connected to Termination Box (M25 Model Shown) 4. Tighten the lock nut against the termination box. See Figure 10. M25 Models M25 models have straight threads and a removable connector assembly with lock nut. Install the sensor as follows: 5. Insert the sensor wires through the connector assembly into the termination box, then secure the sensor to the termination box by tightening the ring on the connector assembly. Prior to tightening the ring, orient the sensor with the set screw away from the detector mounting surface to ensure adequate clearance between the sensor and mounting surface. See Figure 8. 1. Remove the connector assembly from the AC100 Sensor. See Figure 9. 2. Screw the lock nut as far back as it will go (finger tight only), then screw the connector assembly into the appropriate entry on the termination box. A light coating of grease on the threads is recommended. 6. Tighten the connector ring, then install set screws to prevent movement. 3. Screw the assembly into the termination box as far as it will go and tighten with a 35mm socket wrench. note There are a total of six set screw holes on the connector ring, three on the lower level and three on the upper level. Install at least one set screw on each level. See Figure 11.

Conductor insulation should be stripped off with a bare conductor length of 0.2 inch (5 mm) minimum and 0.7 inch (18 mm) maximum. Ensure that cable shield is properly terminated and that bare shield wire is not allowed to accidentally contact the metal housing or any other wire. Figure 16 shows an ATX10 with AC100 wired to a FlexVu UD10 Universal Display. See Figure 17 for benchtop test wiring. note For proper HART communication, a signal loop resistance of 250 ohms must be present at the 4-20 mA output terminals. Important The AC100 GND wire (green, 16 AWG, 1.31 mm2) must be properly grounded inside the STB or ATX10 to maintain proper Intrinsic Safety connections. A lug is provided and must be properly crimped to the wire and secured with the provided screw and washer at the location marked by the GND symbol. The AC100 and the adjoining STB/ATX10 are also provided with an external GND connection (lug screw and washer provided) that must be bonded to a suitable earth GND connection. In addition, the power supply GND must be terminated at the STB/ATX10 to ensure 1 ohm or less resistance. SET SCREWS Figure 12 shows the wiring terminals on the ATX10 Transmitter.

ENABLE • Profile ‑ Level / Learn 3. AUTO LEVEL can be set as follows: Enable AUTO LEVEL via the ENABLE command in the AUTO LEVEL submenu. The detector will automatically select a new LEVEL (dB) setting based on the background noise picked up during a 10 second (not field adjustable) interval. The ATX10 is factory programmed to run in Basic operating mode. This mode of operation uses the simplest setup process, but offers the fewest options for adjusting sensitivity. Profile mode is an alternate option that allows access to additional configuration parameters, as well as the ability to “Learn” background profiles. 4. Set the DELAY (SEC): This delay represents the time that an alarm condition must be held in order to annunciate an alarm (adjustment range = 0-30 seconds, default = 5 seconds). It is normally not necessary to change this value. However, it can be useful to increase the delay if there are false alarms due to momentary events. BASIC mode Basic mode uses a simple alarm detection technique. The detector searches the ultrasonic spectrum for bands that exceed a fixed threshold. When a sufficient number of these bands exceeds the pre-set level, an alarm condition is detected (adjustment range = 40-120 dB, default = 59 dB). If the alarm condition continues for a fixed period of time, an alarm output is generated (adjustment range = 0-30 seconds, default = 5 seconds). The fixed threshold level and the fixed time period are field selectable, and are the only variables that need to be considered in Basic mode. Use the following procedure to configure the detector for Basic operating mode. PROFILE mode In the Profile operating mode, the detector still uses the same alarm detection techniques. However, several additional options and capabilities are offered. Use the following procedure to configure the detector for Profile operating mode. 1. Navigate the HART menu as follows: DEVICE MENU > DEVICE SETUP > ALARM SETUP > MODE > PROFILE. 1. Navigate the HART menu as follows: DEVICE MENU > DEVICE SETUP > ALARM SETUP > MODE > BASIC. DEVICE SETUP ALARM SETUP ALARM SETUP SD MENU SET RTC CALIBRATION MENU WRITE PROTECT HART SETUP MODE BASIC/ PROFILE/ ADVANCED LATCHING BASIC MODE PROFILE MODE PROFILE MODE BASIC MODE LEVEL (dB) DELAY (SEC) AUTO LEVEL ALARM SETUP ALARM SETUP SD MENU SET RTC CALIBRATION MENU WRITE PROTECT HART SETUP MODE BASIC/ PROFILE/ ADVANCED LATCHING BASIC MODE PROFILE MODE ALARM MODE LEVEL/LEARN LEVEL (dB) SENSITIVITY (dB) BAND COUNT DELAY (SEC) RECOVER (SEC) LEARN MENU PREALARM ON PREALARM LVL 2. In the PROFILE MODE menu, select ALARM MODE, and then either LEVEL or LEARN. (The following sections describe the differences between LEVEL and LEARN.) 2. In the BASIC MODE menu, set the LEVEL (dB): This should be set to a numeric value between 40 and 120 (factory default is 59). This represents the threshold at which a leak will be detected and an alarm declared. Lower numbers represent greater sensitivity and higher numbers will result in less sensitivity to alarm. This value can be set manually, or by using the AUTO LEVEL function. 2.5 DEVICE SETUP 21 95-8657 Profile‑Level Profile‑Learn The Profile‑Level mode uses the same fixed threshold concept as Basic mode. There is a LEVEL (dB) setting, but no AUTO LEVEL function. The benefit of using Profile‑Level is that some additional settings are available for increased flexibility. The Profile‑Learn mode uses variable thresholds. Each frequency band has its own threshold level, rather than a fixed level that is applied to all bands. The Profile‑Learn mode uses a recorded set of band thresholds called a “Profile.” The process for generating a profile is referred to as “Learn.” In some applications the use of the factory default settings in the Profile‑Level mode may be adequate, however, it is possible to customize the acoustic detection using the additional settings. The following additional settings are available in Profile‑Level: The detector is commanded to start and stop the “Learn” process to record the maximum sound level detected in each band during the recording period. This data can be used to reduce sensitivity at the frequency bands where background noise and events are prevalent while increasing sensitivity in the bands that are relatively silent. BAND COUNT – In Basic mode, the number of frequency bands that exceed the LEVEL (dB) threshold are counted. An alarm condition exists when this count exceeds 14 bands. This number is fixed in Basic mode. In Profile‑Level mode it can be adjusted (adjustment range = 1-24, default = 14). Lower numbers tend to make the detector more sensitive to narrow band signals, including pure tones or other ultrasonic emitting devices. Higher numbers tend to decrease the sensitivity of the detector and require broadband ultrasonic sound to exceed the LEVEL(dB) threshold in more bands. To perform the Learn process: 1. Navigate to DEVICE SETUP > ALARM SETUP > PROFILE MODE > LEARN MENU. PROFILE MODE ALARM SETUP MODE BASIC/ PROFILE/ ADVANCED LATCHING BASIC MODE PROFILE MODE RECOVER (SEC) – This setting specifies the time (in seconds) that elapses from the moment the alarm criteria are no longer met until the alarm is cleared. ALARM MODE LEVEL/LEARN LEARN MENU LEVEL (dB) SENSITIVITY (dB) BAND COUNT DELAY (SEC) RECOVER (SEC) LEARN MENU PREALARM ON PREALARM LVL LEARN ENABLED? START LEARN STOP LEARN RECORDED CLR RECORDED ALARM PROFILE SAVED PROFILE 2. Select CLR RECORDED to clear any previous learn data, if desired. Any future learn data will build upon previous results unless this step is performed. 3. Select the START LEARN command to start the learn process. LEARN ENABLED? will indicate ‘Y’ 4. Select STOP LEARN to stop the learn process. At this point the sequence of START LEARN/STOP LEARN and/or CLR RECORDED may be repeated until the desired profile data is collected. The profile should be characteristic of typical background sounds that may occur during normal operation. If there are periodic events that cause false alarms, it is desirable to conduct the learn process during these events. 2.5 22 95-8657 5. Once the RECORDED data represents the desired profile, navigate to the SAVED PROFILE menu. The SAVED PROFILE menu provides a preview of several slots for permanently storing the RECORDED profile. Navigate to a slot to overwrite. (Use SLOT 1 for a new unit). PREALARM configuration The PREALARM option is available in Profile-Level/Learn mode (not Basic), and can be configured as follows through the PROFILE MODE menu. 1. Set PREALARM ON to ‘Y’ PROFILE MODE ALARM MODE LEVEL/LEARN LEARN MENU LEVEL (dB) SENSITIVITY (dB) BAND COUNT DELAY (SEC) RECOVER (SEC) LEARN MENU PREALARM ON PREALARM LVL LEARN ENABLED? START LEARN STOP LEARN RECORDED CLR RECORDED ALARM PROFILE SAVED PROFILE 2. Set PREALARM LVL. SAVED PROFILE NAME DATE TIME The alarm threshold for each band is lowered by this value, effectively making the band more sensitive. PREALARM is intended to be more sensitive than the normal alarm and can be used as a warning that a potential alarm condition may be imminent. The number of bands that exceed this lower threshold are counted. When they reach the BAND COUNT setting used for normal alarms, PREALARM will annunciate, resulting in a 16 mA output. 6. Select the slot. The menu that appears shows the options of SELECT and SAVE. First select SAVE to copy the RECORDED profile into the SAVED PROFILE slot. Select SELECT to tell the ATX10 to use this SAVED PROFILE slot as its profile for the alarm function. 7. Navigate back to the LEARN MENU and confirm that the selected slot’s name appears as the ALARM PROFILE. 8. Return to the PROFILE MODE menu and set the following parameters as desired: SENSITIVITY (dB) - The actual alarm threshold used in each band is a combination of the profile and this fixed offset. (i.e. a value of 3 would mean each band is counted towards alarm if it exceeds a level 3 higher than its corresponding level in the profile). RECOVER (SEC) – This setting specifies the time (in seconds) that elapses from the moment the alarm criteria are no longer met until the alarm is cleared. BAND COUNT – Similar to Basic and Profile‑Level operation, the band count can be adjusted in Profile‑Learn. It is preferable to leave the count at the default of 14 or perhaps somewhat higher in Profile‑Learn mode, since a large sensitivity gain is already realized with the use of a profile. A lower band count may make the detector susceptible to narrow band false alarm sources. 2.5 23 95-8657 GENERAL APPLICATION INFORMATION Password protection The ATX10 allows the use of a password for restricting changes to configuration parameters and limiting access to safety critical commands. Nuisance Sources Most industrial or processing environments are relatively free from the higher frequency sound energy that is characteristic of a gas leak, however, there are instances where high frequency nuisance sources exist. The sources may include, but are not limited to: The ATX10 is shipped from the factory with the password protection (Write Protect) feature enabled. Refer to the AC100/ATX10 HART Addendum (number 95-8698) for complete information regarding use of the Write Protect feature. • Rotating machinery / gear meshes • Bearings/fans motors • Metal-to-metal contact / chains • High velocity wind through rigging The FlexSonic Acoustic Detector can be effectively employed to record the acoustic background environment unique to an installation and provide a clear display of the information using the Acoustic Inspector software package. The ability to view the actual acoustic environment enables users of the FlexSonic Acoustic Detector to make intelligent, databased decisions on how to best address nuisance sources in the alarm profile. Friendly Leaks The FlexSonic Acoustic Detector recognizes the acoustic signature of pressurized gas escaping. Therefore, so called ‘friendly’ sources of compressed gas leaks such as air lines and relief stacks may be detected as well. While some non-hazardous pressurized gas escapes may be effectively ignored through the patented learn function, the expected hazardous leak SPL must be greater than the non-hazardous leak SPL for the detector to effectively discriminate between the two sources. If the time duration of the non-hazardous source is relatively short, the user settable alarm delay setting can be adjusted to reject short duration leaks. Refer to the “Operation” section of this manual for details on alarm adjustments. 2.5 24 95-8657 Maintenance Routine Inspection Periodically or during scheduled maintenance, the AC100 cover should be inspected to ensure that obstructions such as plastic bags, litter, heavy oil and tar, paint, mud, snow, or other materials do not block sound from reaching the sensor and thereby impairing the performance of the device. IMPORTANT Periodic flamepath inspections are not recommended, since the product is not intended to be serviced and provides proper ingress protection to eliminate potential deterioration of the flamepaths. When using the optional foam insert in dirty or dusty environments, check to ensure the insert is clean and free of buildup. Replace the insert if torn or damaged. The AC100 Sensor contains no user serviceable components and should never be opened. The ATX10 wiring compartment is the only part of the acoustic detector that should be opened by the user in the field. Cleaning To clean the AC100 Acoustic Sensor cover, ensure that the device is powered off, then simply grasp the cover assembly and twist counterclockwise. See Figure 18. The stainless steel mesh can be cleaned with warm soapy water and rinsed. Remove any excess water with a cloth, then air dry. Note Refer to the FlexSonic Acoustic Detector Safety Manual 95-8658 for specific requirements and recommendations applicable to the proper installation, operation, and maintenance of all SIL-Certified acoustic detectors. The foam insert (if used) can also be cleaned with warm, soapy water and rinsed. Hand wring any excess water by simply squeezing the foam insert to remove excess water. To maintain maximum sensitivity and detection range, the AC100 Acoustic Sensor cover (and optional foam insert) must be kept relatively clean and free of debris. Refer to the following procedure for cleaning instructions. When re-installing the foam insert / AC100 cover, use care not to over tighten. caution The AC100 sensor head (microphone and AIC acoustic source) does not require cleaning and should not be contacted with any cleaning materials.
