3.11.4 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.
Code Name Description of Fault Condition
<0001>
Box
Temperature
Fault
Enclosure temperature is outside normal range (or IR detector has failed). Check that
the monitor is not being subjected to extreme temperatures. Use the DIAG function to
check the Box Temperature.
<0002>
Bench
Temperature
Fault
Optical bench is outside normal operating range (or IR detector has failed). Check that
the monitor is not being subjected to extreme temperatures.
<0004>
Manifold
Pressure Fault
The manifold pressure is outside its normal operating range (or IR detector has failed).
Enter the
DIAG function and record ALL data. Call the factory with this information for
further instructions.
<0040> Fill Flow
The purge-air bag’s pressure drop is outside expected limits. Use the
EMTYBAG and
FILLBAG functions to refill the purge-air bag. If the fault still occurs, check for a
punctured bag or disconnected tubing.
<0080>
Over Range
Fault
Monitor exposed to a gas level that exceeded 65,000 ppm.
<0100> Zero Filter Fault
The air-purge bag is contaminated with gas. Take monitor to a clean-air area and use
the
EMTYBAG and FILLBAG functions several times to decontaminate the purge-air bag.
<0200> Gain Set Fault
The digipot autotune sequence has failed. This fault will only occur on first boot up or
after a firmware upgrade. Call the factory for further instructions.
<0400> A/D Fault
A fault has occurred in the analog-to-digital circuitry. Contact the factory with this
information for further instructions.
<0800>
Sample Flow
Fault
Check for a restriction in the gas-sample inlet or exhaust, a blocked internal filter, or a
failed pump.
<1000>
Purge Flow
Fault
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.
<2000> Bag Fill Time
The purge-air bag did not fill within the expected time allotment, or too many purge
cycles occurred indicating a leak in the purge-air system. Check for a punctured bag or
disconnected tubing.
<4000>
Zero Range
Fault
The IR detector’s output voltage is out of tolerance. Enter the
DIAG function and record
all data. Call the factory with this information for further instructions.
<8000> Clipping Fault
The detector voltage may be out of tolerance. Use the
DIAG function to check the IR
detector voltage. Call the factory with this information for further instructions.
