Viewing the Fault Log 
From the Data Display screen, use the Keypad buttons to place the arrow (>) on the display next to the 
FAULTS function. Then press ENTER to display the fault log. 
The fault log shows the monitor’s current fault status. If the fault is still 
present when the FAULTS function is selected, then the current cause of 
the fault is displayed along with the date and time it occurred. If the cause 
of the fault has been cleared, then the fault log will show <0000> along with 
the date and time the fault was cleared. Use the keypad buttons to scroll 
through the fault log. In the examples shown to the left, record #03 shows 
that a Zone Flow Fault (fault code <0800>) occurred on 11/12/03 at 08:17, 
while record #04 shows that the fault was cleared on 11/12/03 at 8:30.  
The cause of the fault is identified by a numeric fault code.  To convert the 
fault code into a text description of the fault, first press the ENTER button 
and then use the Keypad buttons to scroll through the display until the text 
description of the fault appears. If the fault code is a combination of two or 
more faults, then continue to use the Keypad buttons until all fault text 
descriptions have been displayed. For example, the fault code <1800> 
represents the combination of both a Zone Flow <0800> and a Purge Flow 
<1000> fault as shown to the left. 
Note that the Fault Log can be cleared as described in Section Clearing the Stored PPM Log, Alarm & 
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
<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 21) 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 21) 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 11). 
<0100> Zero Filter Fault: There is refrigerant 
gas present in the purge air. Locate the monitor in 
an area containing fresh air, or install a purge air 
<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 8); 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 8); 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 21) 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 21) to check the IR detector voltage. Call the 
factory with this information for further 
instructions.
