3.10 Working with System Faults
3.10.1 Functional Overview
If a system malfunction occurs (see Fault Code list, page 19), the front panel FAULT light will flash and
the audible alarm, if activated (refer to AUDALRM function page 16), will start beeping.
3.10.2 Clearing / Silencing a Fault Alarm
The FAULT light and audible alarm will automatically turn OFF after the cause of the fault has been
eliminated.
Pressing the SILENCE button while a fault condition still exists causes the internal audible alarm to turn
OFF for a period of time as set by the SILENCE function (page 17). The front panel FAULT light will
continue to flash as a reminder that a fault condition still exists. At the end of the silence period if the
cause of the fault has not been corrected the audible-alarm circuit will reactivate.
3.10.3 Viewing the Faults Log
From the Data Display screen, press any of the Keypad buttons to display the first Function Menu
screen. Next, use the Keypad buttons to move the arrow (>) until it points to the FAULTS function, and
then press the ENTER button to display the Faults Log screen.
The Faults Log screen 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 Faults Log
screen 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
screens shown to the left, record #03 shows that a Sample Flow Fault (fault
code <0800>) occurred on 07/11/2005 at 08:17 AM, while record #04 shows
that the fault was cleared on 07/11/2005 at 9:00 AM.
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 Sample Flow <0800> and a Purge
Flow <1000> fault as shown to the left.
The Fault Log can be cleared as described under the heading Clearing the
PPM and Faults Data (Section 3.13).
