Error CodeError Code
A deviation band alarm presets two reference levels relative to set point. Two
types of deviation band alarm can be configured for alarm 1 and alarm 2. These
are deviation band high alarm (A1FN or A2FN select DB.HI) and deviation
band low alarm (A1FN or A2FN select DB.LO). If alarm 2 is required, then
select =AL2 for OUT2. Now A2FN can't be selected with NONE, otherwise
will appear. A1SP and A1HY are if alarm 1 is selected with
deviation band alarm. Similarly, A2SP and A2HY are if alarm 2 is
selected with deviation band alarm.
Trigger levels of the deviation band alarms will move with the set point.
For alarm 1, the trigger level=SP1 A1DV.
For alarm 2, the trigger level=SP1 A2DV.
One of 4 kinds of alarm modes can be selected for alarm 1 and alarm 2. These
are: Normal alarm, Latching alarm, Holding alarm and Latching/Holding alarm.
See for descriptions of these alarm modes.
