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.
Immediately after selecting the FAULTS function, the most recent fault event is displayed. The fault log identifies the type of fault, plus the date and time it occurred. In the example below, record #03 shows that a Zone Flow Fault (fault code <0800>) occurred on 11/12/03 at 08:17.
#03 <0800> @ 11/12/03 08:17
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 below:
FAULT CODE<1800>
12 ZONE FLOW
FAULT CODE<1800>
13 PURGE FLOW
Note that the Fault Log can be cleared as described in Section Clearing the Stored PPM Log, Alarms & Faults Data on Page 20.
Fault Codes
<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 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 and record ALL data. Call the factory with this information for further instructions.
<0010> Loop Fault: The
<0100> Zero Filter Fault: A purge filter failure has occurred. Replace the unit’s charcoal filter.
<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
<0800> Zone Flow Fault: Check for: A kink in the
<1000> Purge Flow Fault: Check that the internal charcoal filter inlet (Page 8) is not blocked. 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 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 to check the IR detector voltage. Call the factory with this information for further instructions.
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.
