2.11.4 Fault Codes

FAULT CODES ARE ADDITIVE. For example: A fault code of <0003> indicates that both a Box Temperature Fault
<0001> and a Bench Temperature Fault <0002> have occurred.

2.12 Clearing the PPM, Alarms and Faults Data

Up to 200 gas measurements and 30 alarm and fault events are stored by the monitor.
To clear stored data, first display the data to be cleared by selecting the PPM LOG, ALARMS or FAULTS function.
Next, press both the ENTER and Keypad Right buttons at the same time. A single, long tone should be heard when
the data has been successfully cleared.

Enclosure temperature is outside normal range (or IR detector has failed).
Check that the monitor is not being subjected to extreme temperatures. Use
the function to check the Box Temperature.
DIAG
Optical bench is outside normal operating range (or IR detector has failed).
Check that the monitor is not being subjected to extreme temperatures.
The manifold pressure is outside its normal operating range (or IR detector
has failed). Enter the
DIAG
this information for further instructions.
See fault code <0004>.
The purge-air bag's pressure drop is outside expected limits. Check for a
punctured bag or disconnected tubing.
Monitor exposed to a gas level that exceeded the IR sensor limits.
The purge-air bag is contaminated with gas. Take monitor to a clean-air area
and use the EMPTYBAG and FILLBAG functions to decontaminate the purge-
air bag.
The digipot autotune sequence has failed. Call the factory for further
instructions.
A fault has occurred in the analog-to-digital circuitry. Contact the factory
with this information for further instructions.
Check for: A restriction in the gas-sample inlet or exhaust; a blocked internal
filter; or a failed pump.
Check for: A restriction in the gas-sample exhaust; a blocked internal filter;
or a failed pump. Once the purge air stream has been restored, the monitor
will return to normal operation after it completes a purge cycle.
The purge-air bag did not fill within the expected time allotment. Check for a
punctured bag or disconnected tubing.
The IR detector's output voltage is out of tolerance. Enter the
and record all data. Call the factory with this information for further
instructions.
The detector voltage may be out of tolerance. Use the
the IR detector voltage. Call the factory with this information for further
instructions.
