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.
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
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
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,
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
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
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
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.
