Table 7—Troubleshooting Guide
Fault Condition
Corrective Action
Low 24 volts
24 vdc operating voltage is out of range. Verify proper wiring to the detector and correct
voltage output from the power source. Power supply faults are self-clearing when the
condition is corrected. If the fault does not clear, consult the factory.
Dirty Optics
Perform cleaning procedure, then re-calibrate as required. (Refer to “Maintenance” for
details.)
Calibration Fault
If the calibration process is allowed to time-out, the fault is set and can only be reset
with a successful calibration. Check the gas bottle to ensure that there is enough gas
to complete the calibration. Are conditions too windy for a successful calibration? If
so, use a PointWatch Eclipse Calibration Bag (P/N 006672-002). Always calibrate
with a Det-Tronics calibration kit for Eclipse with correct regulator. Be sure that the
calibration gas being used matches the configured setting. If the fault is still present,
perform cleaning procedure, then re-calibrate.
Negative Signal Output
This fault is indicated when the signal output drops below 10% of scale. Normally detection
capability is not compromised in this condition. The device was probably zero calibrated with
background gas present. If the condition persists, purge with pure nitrogen and repeat the
zero calibration.
Calibration line active at start-up
The only way to clear this fault is to correct the wiring and reapply power. Be sure that the
calibration line is not shorted and that the calibration switch is open. If the fault does not clear,
consult the factory.
Other Faults
Consult the factory.
