Alarms can have the following states:
Alarm Ok – all alarms are off.
Alarm Delay
– pressure and liquid level alarms have a timeout period.
These alarms will wait a certain period of time before putting the
system into an alarm state. During the timeout period the heater is
put in a safe state while waiting for these alarms to clear themselves
and the alarm will be in the alarm delay state. If these alarms clear
themselves before the timeout period elapses, the heater will go back
to normal operation without alarming. If these alarms do not clear
themselves before the timeout period expires, the heater will alarm.
The time delay for these alarms is set on the system configuration
page.
Alarm Active – any alarm that has not been cleared and is still active
is in this state.
Alarm On
– any alarm that has not been cleared but is no longer
active is in this state.
