How to fix CL96 System Fan Failure on DOD Gas Detectors?
- RRyan DukeSep 12, 2025
If the DOD Gas Detectors unit displays 'CL96 System Fan Failure', it means that fan on side panel has failed. Replace fan on CL96 side panel.
How to fix CL96 System Fan Failure on DOD Gas Detectors?
If the DOD Gas Detectors unit displays 'CL96 System Fan Failure', it means that fan on side panel has failed. Replace fan on CL96 side panel.
What does Idle Timeout (Analyzer) mean on DOD Gas Detectors?
If the DOD Gas Detectors unit displays 'Idle Timeout (Analyzer)', it means that an analyzer was left out of analysis for a time frame that overlapped the time out setting. Check to see if a fault caused the CL96 to leave analysis and if not put the CL96 back into analysis.
What causes Idle Timeout (System) on DOD CL96 Gas Detectors?
If the DOD Gas Detectors unit displays 'Idle Timeout (System)', it means that CL96 was left out of analysis for a time frame that overlapped the time out setting. Check to see if a fault caused the CL96 to leave analysis and if not put the CL96 back into analysis.
What does 'Low Flow - Verify Tray Insertion' mean on DOD CL96 Gas Detectors?
If your DOD Gas Detectors is showing 'Low Flow - Verify Tray Insertion', it means that the flow is low for multiple points on an analyzer. Make sure all points are flow balanced and refer to Flow Path verification procedure.
What to do if DOD Gas Detectors show Gas Alarm Level 1?
If the DOD Gas Detectors indicate a Gas Alarm Level 1, it signifies a gas release exceeding Alarm Level 1. You should determine the release point.
What to do for Block Below Minimum Voltage error on DOD Gas Detectors?
If the DOD Gas Detectors unit displays 'Block Below Minimum Voltage', it means the optic block voltage dropped below the required voltage of 5.1 V. Verify the 5V supply is turned up to 6.1 VDC, verify all optic blocks have at least 5.4 VDC and see Optic Troubleshooting Procedure.
What does Retentive Memory Error mean on DOD CL96?
If the DOD Gas Detectors unit shows 'Retentive Memory Error, History and/or Tape counters may be corrupt', it means the system was unable to load previous historical events after power cycle. Power cycle CL96 to resolve this.
How to troubleshoot Pyrolyzer Control Module Fault on DOD CL96?
If the DOD Gas Detectors unit displays 'Pyrolyzer Control Module Fault', it indicates a communication issue between the PC and pyrolyzer control modules. Verify the connection of communication modules, unplug and re-insert cables on communication module, power cycle CL96, and replace communication modules.
Why is DOD Gas Detectors Setting DAC to preset values?
If the DOD Gas Detectors unit is 'Setting DAC to preset values', it means that CL96 was unable to set DAC values back to previously retained values. Power cycle analyzer to resolve this.
Why is the point disabled due to high background on DOD Gas Detectors?
If the DOD Gas Detectors unit displays 'Point Disabled Due to High Background', it means a point has been disabled because of a high background. Press the Verify Optics button in the Load Tape screen.
