Chapter 4—Front Panel Operation

CLEARING To provide a record of high priority alarm occurrences available for display
THE PRIORITY 1 LOG from the front panel, the circuit monitor maintains a priority 1 log (P1 log).
See Setting Up Alarm/Relay Functions in this chapter for a complete
description of the priority levels, and instructions on assigning priority levels
from the front panel. See Viewing the Priority 1 Log on the previous page
for instructions on viewing the P1 log.
The P1 log stores up to 10 of the last priority 1 alarms. The log operates in a
first-in-first-out (FIFO) manner. In other words, when the log is full, the first
alarm entry in (the oldest) is the first out.
When a priority 1 alarm occurs, the circuit monitor records it in the P1 log.
The alarm remains in the P1 log until one of the following occurs: 10 new P1
alarms occur (pushing it out of the log), or you manually clear the P1 log.
The procedure below tells how to clear the P1 log.
IMPORTANT: Clearing the P1 log causes the circuit monitor to release all
relays that meet the following conditions:
The relay must be configured to operate in latched mode.
The relay must be configured for internal control. In other words, you
must have set up the circuit monitor to operate the relay in response to an
alarm condition.
All alarms assigned to operate the latched relay must not be in their alarm
state.
To clear the P1 log, complete the following steps:
1. Press the MODE button until the red LED next to ALARM glows
steadily.
The circuit monitor displays “P1.Log.”
2. Press the SELECT METER [Value] buttons until “CLEAr” is
displayed.
3. Press the PHASE [Enter] button.
The circuit monitor displays “CLr. No”.
4. To abort the clear, press the PHASE [Enter] button.
5. To clear the log, press the up arrow SELECT METER [Value] button to
change from “CLr. No” to “CLr.YES.” Then press the PHASE [Enter]
button.
The circuit monitor clears the P1 Log, and releases any relays that meet
the conditions described above.
