Alarms
When alarms are activated they are displayed in the alarm queue and also as a
blinking red light on the display panel on the front of the controller. Certain alarms
cannot be traced to one of the 7 LEDs on the panel and therefore have no separate
alarm on the front. The alarm lamp above the alarm button always blinks red,
however, in the event of an alarm.
Alarm queue
To check the alarm queue press the alarm button
. The display will then show
active alarms, the date and time when the alarm became active and the alarm
status.
Alarm status
Blinking ”AL” indicates that the alarm is active and has not been
acknowledged.
Steady ”AL” indicates that the alarm is active but has been acknowledged.
Blinking ”OK” indicates that the alarm has aborted but has not been
acknowledged.
Acknowledging an alarm
Alarms are acknowledged by means of the
OK
button which will remove the alarm
from the alarm list. If the alarms are still active they will remain in the alarm list but
the blinking will be replaced by a steady ”AL” and a steady red light on the alarm
signals.
Arrows on the right-hand side show when there are more alarms in the queue.
Login
