3.3.8 Failure
Alarms
When a failure is detected by the automatic supervision, it is followed with an LCD message, LED
indication, external alarm and event recording. Table 3.3.1 summarizes the supervision items and
alarms.
The LCD messages are shown on the "Auto-supervision" screen, which is displayed automatically
when a failure is detected or displayed by pressing the
VIEW
key. The event record messages are
shown on the "Event record" screen by opening the "Record" sub-menu.
The alarms are retained until the failure is recovered.
The alarms can be disabled collectively by setting the scheme switch [AMF] to "OFF". The setting
is used to block unnecessary alarms during commissioning, test or maintenance.
When the Watchdog Timer detects that the software is not running normally, LCD display and
event recording of the failure may not function normally.
