3.5.4. Fault Codes
FAULT CODES ARE ADDITIVE. For example: A fault code of <1800> indicates that both a Purge Flow
Fault <1000> and a Zone Flow Fault <0800> have occurred.
Code Name Description
<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. Verify that the ventilation holes are not obstructed.
Use the DIAGNOS function (page 26) 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 normal operating range (or IR
detector has failed). Enter the DIAGNOS function (page 26) and
record ALL data. Call the factory with this information for further
instructions.
<0010> Loop Fault The 4–20 mA current loop is open, or there is a high resistance in the
circuit. Check the wiring to the load/monitoring circuit. If this feature is not
being used, a 100 ohm resistor must be connected to the 4–20 mA
connector (page 16).
<0100> Zero Filter Fault There is gas present in the purge air. Locate the monitor in an area
containing fresh air, or install a purge air line. Refer to page 7.
<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> Zone Flow Fault Check for:
A kink in the gas-sample line or exhaust line; a blocked external
termination filter; a blocked internal hydrophobic filter (page 11); a
failed pump.
<1000> Purge Flow Fault Check for:
A kink in the purge line; a blocked external termination filter; a
blocked internal hydrophobic filter (page 11); a failed pump. Once
the blockage has been cleared, the monitor will return to normal
operation after the monitor completes a purge cycle.
<4000> Zero Fault The IR detector’s output voltage is out of tolerance. Enter the
DIAGNOS function (page 26) 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 DIAGNOS
function (page 26) to check the IR detector voltage. Call the factory
with this information for further instructions.
