3.5. System Faults
3.5.1. Overview
If a system malfunction occurs, the SZ monitor will detect the problem and turn ON the front panel
SYSTEM FAULT light. Additionally, an external alarm device may activate and the monitor’s internal
audible alarm may sound if those features have been enabled (pages 14 and 22).
3.5.2. Clearing / Silencing a Fault Alarm
The SYSTEM FAULT light and all other fault indicators 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 and the
external alarm device that is connected to the fault relay to turn OFF for a period of time as set by the
SILENCE function (page 22). The front panel SYSTEM FAULT light remains ON, however, as a reminder
that a fault condition still exists. The alarm circuit will reactivate at the end of the silence period if the
cause of the fault has not been corrected. The SYSTEM FAULT light will automatically turn OFF once the
fault has been cleared.
3.5.3. 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 11/12/10
at 08:17, while record #04 shows that the fault was cleared on 11/12/10 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 on page 25.
