Latching Alarm : ALMD = LTCH
If a latching alarm is selected, once the alarm output is energized, it 
will remain unchanged even if the alarm condition is cleared. The 
latching alarm is reset when the RESET key is pressed, once the alarm
condition is removed.

Latching Alarm : ALMD = LTCH

Holding Alarm : ALMD = HOLD
A holding alarm prevents an alarm at power up. The alarm is 
enabled only when the process reaches the set point value. Afterwards
, the alarm performs same function as normal alarm.

Holding Alarm : ALMD = HOLD

Latching / Holding Alarm : ALMD = LT.HO
A latching / holding alarm performs both holding and latching function.
The latching alarm is reset when the RESET key is pressed, once the 
alarm condition is removed.

Latching / Holding Alarm : ALMD = LT.HO

Alarm Failure Transfer is activated as the unit enters failure mode. 
Alarm will go on if ON is set for ALFT  and go off if OFF is 
set for ALFT. The unit will enter failure mode when sensor break 
occurs or if the A-D converter of the unit fails.

Normal Alarm : ALMD = NORM
When a normal alarm is selected, the alarm output is de-energized 
in the non-alarm condition and energized in an alarm condition.

Normal Alarm : ALMD = NORM
