As the detector senses ultrasonic noise, the Gassonic Surveyor does not have to be in contact with the leaking gas itself. It will detect the gas leak instantly even if the gas is carried away by wind or diluted in the air. The Gassonic Surveyor can be used in configurations with other detection methods.
2.1 - noiSe leVelS It is helpful to know the actual noise level before installation, as this has influence on the Gassonic Surveyor’s detection range. Most environments can be divided in three overall noise levels. 1m 2m 3m 4m 5m 6m 7m 8m 9m 10m 11m 12m 13m 14m 15m 16m...
In special cases, such as installation over compressors, the height can be increased. The Gassonic Surveyor can be mounted on a pole or a wall using the optional mounting bracket UA1352A for standard horizontal mount- ing or on the 45° mounting bracket UA1353. It can also be mounted on a ceiling, on structural beams or similar non-vibrating structures.
The bottom part of the detector is supported by the Load-strap, which is connected to the top part. The Gassonic Surveyor is mounted from the top with two 8 mm stainless steel bolts. Maximum thread depth is 15 mm. To open the unit, loosen the four screws.
When closing the top chamber ensure that the Load-strap and wires are not caught between the bottom part and the top part of the detector. Check the status of the rubber sealing and the flange. Send the unit to Gassonic for repair if the flange and/or the rubber sealing is damaged.
5.0 - alaRm delaY and TRiGGeR leVel An alarm delay time prevents false alarms when the Gassonic Surveyor detects spikes of high level ultrasonic Alarm Delay time noise. After the delay time has run out an alarm will be Trigger level triggered, but only if the noise level is still above the trig- ger level.
480 (8 minutes) 5.4 - eRRoR RelaY In Error relay mode the Gassonic Surveyor will indicate low supply voltage by deactivating the relay, swiching off the user LED and flashing the communication LED. The Error relay is always NC (normally closed).
6.0 - TeST and caliBRaTion The Gassonic Surveyor is tested and calibrated as part of the manufacturing process. However, prior to use, it is good practice to calibrate and test the unit. This can be done using the Gassonic 1701 test and calibration unit.
5. If the test is more than ± 3 dB out of tolerance, perform calibration. If the test was faulty the Gassonic 1701 beeps three times and a No response message displays on the screen. Press Enter to No response try again, or check the “Trouble shooting”-chapter...
Press Enter when the LED flashes red. The delay shows on the screen. If you use the Delay on: analog 4-20 mA output, press Enter when 0:10 the control room observes an alarm. Installation and User Guide for Gassonic Surveyor (BB6019-01) Page 12...
9.0 - caliBRaTion pRoceduRe A calibration can be performed at any time. Along with the Gassonic 1701, you will need the magnet-stick to set the Gassonic Surveyor in calibration mode. acTion BuTTon diSplaY BuTTon Switch the Gassonic 1701 tool on. The ver- Select sion number will display briefly.

The Gassonic complete Surveyor LED turns green. If the test was faulty the red LED on the Gassonic 1701 flashes and the message “No response” is displayed on the screen. The No response Gassonic Surveyor user LED will flash green for 5 seconds and then the unit will return to normal operation.

GaSSonic SuRVeYoR led inTeRFace The Gassonic Surveyor has two interface LEDs, which will flash red or green depending on the state of the unit. The LED on the front of the unit indicates the current mode of the Gassonic Surveyor, and the LED next to the sensor head communicates with the test- and calibration tool Gassonoc 1701.
