System Screen Fault Screen
4.8.3. Critical Faults
• NO FLOW ON ZONE – On the System Screen, select ZONES. The Zone Screen will
display a “NO FLOW” message in each individual zone affected. Check for a blockage in the
air sample line or at the line end filter. After the blockage has been cleared, the gas monitor
will return to normal operation after the zone has been sampled. NOTE: This may take
several minutes since it is dependent upon how m
any zones there are and their lengths. The
gas monitor will clear the fault the next time it polls the effected zone and the MZ-RD will
return to normal operation the next time that it polls the gas monitor.
• NO FLOW ON PURGE – Check the purge line for a blockage. Verify that the length of the
purge line and exhaust line do not exceed 300 feet (91 m) in length.
• NO FLOW DETECTED – Check for proper pump operation. Check the water trap – drain if
necessary.
• CLIPPING FAULT – The detector voltage may be out of tolerance. Check the Diagnostic
Screen for the DET voltage, AVE voltage and ZERO voltage. Call the factory with this
information for further instructions.
• REZERO VOLT TOL – The detector output voltage is out of tolerance. Check the
Diagnostic Screen and contact the factory for assistance.
• TRIGGER FAULT – No trigger from IR source pulser. Contact factory with all information
from the DIAGNOSTIC SCREEN for farther instructions.
