Output 2 can be selected as an alarm output. There are 6 types of alarm functions and one dwell timer that can be
selected. Four seperate alarm modes (ALMD) can additionally be applied to each alarm function.

sets two absolute trigger

levels. When the process is higher than
SP2, a process high alarm

occurs,

and the alarm is off as the process is lower
than SP2-O2HY. When the process is lower
than SP2, a process low alarm
occurs and the alarm is off as the process
is higher than SP2+O2HY. A process alarm
is independent of set point.

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
When a normal alarm is selected, the alarm output is de-energized in the non-alarm condition and energized in
an alarm condition.

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
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.

Holding Alarm : ALMD = HOLD
A holding alarm prevents or inhibits an alarm from kicking on during initial controller power up. The alarm is enabled
only when the process reaches the set point

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.
