Alarm Modes
‘
no’ means that the alarm will be non-latching.
‘
YES’ means that the alarm will be latched, with
automatic resetting. Automatic resetting means that
if a reset is actioned before the alarm has cleared,
then it will automatically reset when it clears.
‘
Evnt’ means that the alarm is used to trip
an external event. If this option is selected the
front panel alarm message will not appear.
‘
mAn’ means that the alarm will be latched,
and can only be reset after it has first cleared
(called ‘manual reset mode’).
