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.
#03 <0800> @ 11/12/03 08:17
#04 <0000> @ 11/12/03 08:30
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.
FAULT CODE<1800>
12 ZONE FLOW
FAULT CODE<1800>
13 PURGE FLOW
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 Data (Page 20).
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
<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 line. Refer to Locating the Monitor (Page 5).
<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 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.
