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.
