3.8.4 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
Type
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.
Use the
DIAG
function to check the Box Temperature.
<0002> Bench Temperature
Fault
Optical sensor 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.
<0080> Over Range Fault
Monitor exposed to a gas level that exceeded 65,000 ppm.
<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.
<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.
3.9 Working with the Gas Alarm (Area Monitoring)
3.9.1 Gas-Alarm Light
If the detected gas level reaches the gas-alarm level as set by the ALRMLVL function, the front panel ALARM
(red) light will flash and the audible alarm, if activated (refer to AUDALRM function in the Function Screens
section on page 15), will start beeping. The ALARM light and audible alarm will automatically turn OFF once the
detected gas level drops below the gas-alarm level.
3.9.2 Silencing a Gas Alarm
Pressing the SILENCE
button while the alarm circuit is activated causes the audible alarm to turn OFF for a period
of time as set by the SILENCE
function. The front panel ALARM light will continue to flash as an indication that
an alarm condition still exists. At the end of the silence period if the detected gas level is still above the gas-
alarm level the audible alarm will reactivate.
