Alarms
If an alarm occurs, an eight character alarm code is
displayed in the lower-right section of the display.
These alarm codes and messages are shown in the table
below.
Acknowledging an Alarm
Press the Alarm Acknowledge key to acknowledge an
alarm. If there are other channels with alarm conditions,
the Alarm display switches to the next channel in alarm.
Acknowledge all alarms to clear the global alarm.
The Alarm Acknowledge key operates differently in latched
and unlatched modes. In latched mode, an alarm can only
be cleared when the process is in a non-alarming state, and
the Alarm Reset key is pressed. In un-latched mode, the
alarm clears automatically when the Alarm Acknowledge
key is pressed and the system is in a non-alarming state.
Resetting an Alarm
Pressing the Alarm Reset key clears an alarm only if the
system in a non-alarming state. Otherwise, the key will
operate the same as the Alarm Acknowledge key.
