HART or MODBUS interfaces. Please consult the corresponding chapter for instructions.
Unstable detector reading
Verify that the detector has sufficient local
Earthing.
Too low gas reading when exposed to
test gas
● Weather conditions not taken into
consideration (wind and ambient
pressure has impact)
● Too low flow of test gas
● Too short test time to let test gas reach
detector and fill test area
Fault reading in
control room
Detector passed troubleshooting
Frequent cleaning of optics required.
Check that the detector has been mounted
in correct orientation as stated in the
Manual. If it is mounted vertically dust and
water will accumulate on the optics.
