The DIAG function displays sensor data and status information useful to users for troubleshooting 

various fault conditions. Explanations of the data shown in these screens are given below.

First diagnostic screen

Code

Type

Description

<0001>

Box Temperature Fault

Enclosure temperature is outside normal range (or IR detector has 
failed). Monitor has been subjected to extreme temperatures potential 
damage to the unit.
Contact service department for further instructions.

<0002>

Bench Temperature Fault

Optical sensor is outside normal operating range (or IR detector has 
failed). Monitor has been subjected to extreme temperatures potential 
damage to the equipment.
Contact service department for further instructions.

<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. 
Contact service department for further instructions.

<0040>

Fill Flow Fault

The purge-air bag’s pressure drop is outside expected limits. Check for 
a punctured bag or disconnected tubing. Refill the bag using FILLBAG 
function - see manual for instruction.
If the issue persist contact service department.

<0080>

Over Range Fault

Monitor exposed to a gas level that exceeded 65,000 ppm

<0100>

Zero Filter Fault

PGM for halocarbons indicates contamination in the carbon filter. The 
filter need to be replaced, replace the filter.

PGM for CO2

 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,
If the issue persist contact service department.

<0200>

Gain Set Fault

The digipot autotune has failed.
Contact service department for further instructions.

<0400>

A/D Fault

A fault has occurred in the analog-to-digital circuitry. Turn on/off unit if 
the issue persist. Contact service department for further instructions.

<0800>

Sample Flow Fault

Check for a restriction in the gas-sample inlet or exhaust. Check the 
external Coalescing Inline Filter and/or internal Hydrophobic Filters 
replace if necessary. Once the air stream has been restored, the 
monitor will return to normal operation after it completes a purge 
cycle. If the issue persist contact service department.

<1000>

Purge Flow Fault

Check for a restriction in the gas-sample exhaust. Check the external 
Carbon Filter and/or internal Hydrophobic Filter replace if necessary.
Once the purge air stream has been restored, the monitor will return to 
normal operation after it completes a purge cycle.

<2000>

Bag Fill Fault

A punctured bag or disconnected tubing. Refill the bag, FILLBAG 
function - see manual for instruction. If the issue persist contact service 
department.

<4000>

Zero Range Fault

The IR detector’s output voltage is out of tolerance. Enter the DIAG 
function and record all data.
Contact service department for further instructions.

<8000>

Clipping Fault

The detector voltage may be out of tolerance. Use the DIAG function to 
check the IR detector voltage.
Contact service department for further instructions.

Screen item

Description

Sensor voltage

This is the current peak-to-peak output of the IR detector. In the absence of gas this 
value can range from 3.90000 – 4.50000 V

Noise

The noise value is a 16 point running average of the noise portion of the IR detector’s 
output. This reading is valuable mainly when gas is NOT present.

Detector Temperature

This is the current detector temperature in °C

Box Temperature

This is the current internal enclosure temperature in °C

Fault Code

Current fault code. A value of <0000> indicates that no faults are being detected.

Pressure Reading

This is the pressure as measured every purge cycle with the sample pump off and the 
gas-sample inlet open. Its value is weather and altitude dependent and can range 
from 10.0 – 15.5 PSIA.

Purge Valve Asterisk (*)

The purge valve can be opened and closed by pressing the 

Keypad Left

 

button

. An 

asterisk appears on the display when the purge valve is open causing the monitor to 
draw air from its purge-air port.
