INSTRUCTIONS FlexSonic™ Acoustic Detector AC100 Sensor ATX10 Transmitter Overview The FlexSonic™ Acoustic Detector is designed to recognize the unique ultrasonic frequency content of events such as gas leaks. 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).

ATX10 The main function of the ATX10 Transmitter is to evaluate the incoming acoustic power spectrum data from the AC100 Acoustic Sensor and make a determination of alarm condition. The transmitter communicates with the sensor via proprietary serial connection. TEST SWITCH ALARM LED FAULT LED TEST ALARM Operating Power FAULT The acoustic detector operates on 24 Vdc nominal (9 to 30 Vdc total range) system power via wired connection to terminal blocks in the transmitter junction box.
Acoustic Integrity Check (AIC) Manual AIC The AC100 Acoustic Sensor includes an integrated acoustic source capable of providing a variable frequency/amplitude output for system self test. Based on the proven innovation of Det-Tronics’ flame detector optical integrity (oi®) model, the Acoustic Integrity Check (AIC) capability automatically or manually tests the sensor to verify proper operation and is user programmable.
OPERATION Event Logging The ATX10 Transmitter generates an event log and saves the data to onboard flash memory where it can be retrieved via the HART interface. The following events are recorded to the ATX10 event log: The FlexSonic Acoustic Detector has two different modes of operation — Basic and Profile.
Table 2—Profile Mode Alarm Settings Profile Type Learn or Level Parameter Level (dB) Delay Sec) Recover (Sec) Pre-Alarm On Pre-Alarm Level Sensitivity (dB) Band Count Range 40 - 120 0 - 30 0 - 30 Yes / No 0 - 99 dB 0 - 20 1 - 24 Increment 1 1 1 N/A 1 dB 1 1 Default 59 5 1 No 6 dB 4 14 Profile Mode SD Memory Module The Profile Mode of operation includes user adjustments for Pre-Alarm setting, and allows the use of either a level alarm threshold, or a dynamic alarm profile
DOWNLOAD – This command modifies the ATX10 flash memory by replacing all configuration and profile data with the contents of the files on the SD Memory Module. In other words, the data is downloaded to the ATX10 onboard flash from the SD Memory Module. Figure 3 is a flow chart showing how the Memory Module annunciations arise, and the user intervention options that are available to get the Memory Module synchronized and operating normally.
Prior to removal of the Memory Module/SD card, it is recommended that the REMOVE option be selected via HART. This will disable communication to the SD card and annunciate an advisory fault. This is similar to selecting the option to “Safely Remove” a flash drive on a PC. SD Memory Module Removal / Replacement The ATX10 Memory Module is a dual plug daughter board located on the back side of the ATX10 transmitter module. See Figure 4 for location.
UNLOCK STEP #1 SLIDE THE LOCKING CONNECTOR BACK APPROXIMATELY 1/8 INCH (3 MM) TO UNLOCK THE SD CARD. STEP #2 WHEN UNLOCKED, THE CARD/CONNECTOR ASSEMBLY AUTOMATICALLY OPENS TO THIS POSITION. STEP #3 MOVE THE CARD/CONNECTOR ASSEMBLY TO THIS “FULL OPEN” POSITION. BEFORE REMOVING THE CARD, NOTE ITS POSITION. THE CARD MUST BE RETURNED TO THIS EXACT POSITION LATER IN ORDER TO CLOSE THE CONNECTOR. STEP #4 REMOVE THE SD CARD. WITH THE CARD REMOVED, THE CONNECTOR LIES FLAT AGAINST THE CIRCUIT BOARD.
Important Safety Notes installation 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 codes. If in doubt, consult the authority having jurisdiction before wiring the system. Installation must be done by a properly trained person.
Grease/Lubrication To ease installation and future removal, ensure that all junction box covers and sensor threads are properly lubricated. If the need arises for additional lubrication, use either Lubriplate grease (see Ordering Information for part number) or Teflon tape. Avoid the use of silicone grease.
Detection coverage is specified as a radius with the leak source at or below detector level, and unobstructed by infrastructure. Detection Coverage The FlexSonic Acoustic Detector is an omni-directional acoustic analyzer that can recognize the unique frequency content of events such as gas leaks.
power SUPPLY requirements 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. 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.

Startup ALARM SETUP MODE BASIC/ PROFILE/ ADVANCED LATCHING BASIC MODE PROFILE MODE The following section describes configuration of the acoustic detector (using a HART handheld device) for the following modes of operation: • Basic BASIC MODE LEVEL (dB) DELAY (SEC) AUTO LEVEL AUTO LEVEL ENABLED? ENABLE • Profile ‑ Level / Learn 3. AUTO LEVEL can be set as follows: Enable AUTO LEVEL via the ENABLE command in the AUTO LEVEL submenu.
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.
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.
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.
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.
TROUBLESHOOTING If a Fault condition is indicated by the LED on the ATX10 faceplate, the nature of the fault can be determined by navigating to the STATUS INFO MENU. See Table 3 for additional information. Table 3—Troubleshooting Guide Fault Indication Description Corrective Action AI FAULT AIC has failed. Microphone or emitter is degraded. Provide data log information to Det-Tronics for analysis. SD ADVISORY SD Memory Module has an issue that requires intervention via the SD ADVISORY menu.
