What to do if Simtronics Gas Detectors display error 22, no contact with RX?
If your Simtronics Gas Detectors display error 22, indicating no contact with RX, check the power on RX. Also, check the wiring on terminals 1, 2, 11, and 12 in both TX and RX Junction Boxes.
Why is the H2S level fluctuating on my Simtronics Gas Detectors?
A fluctuating H2S level on your Simtronics Gas Detectors might be due to a noisy signal. In this case, tune the alignment. It could also be due to an interfering detector.
What to do if Simtronics Gas Detectors display error 17, unable to track the CO line 2?
If your Simtronics Gas Detectors display error 17, indicating an inability to track the CO line 2, verify that the distance between the TX and RX is 5 meters or more, as a too short path length can cause this issue.
Why is the absolute transmission not as high as expected during alignment of my Simtronics Gas Detectors?
If the absolute transmission is not as high as expected during alignment of your Simtronics Gas Detectors, it could be due to dirty optics; clean the optics. It may also be caused by non-optimum alignment of the TX; in this case, perform tuning of TX. Finally, non-optimum alignment of the RX could be the cause, so perform tuning of RX. Another reason is that the laser beam is obstructed by an object, so move the obstructing object or the GD1.
What to do if there's a loose wire in the junction box of Simtronics Gas Detectors?
If you suspect a loose wire in the junction box of your Simtronics Gas Detectors, check terminals 3 – 6. Unscrew each wire, both internal and external wiring to the terminals, and ensure wires are properly connected to the terminals.
