Band Alarm 2 If Alarm 2 is a Band Alarm, the band
of process variable values, centred
on the (program) setpoint, outside
which the process variable will cause
this alarm to be active (see Figure

Deviation
Alarm 2
If Alarm 2 is a Deviation Alarm, gives
a value above (positive value) or
below (negative value) the (program)
setpoint. If the process variable
deviates from the setpoint by a
marging greater than this value, the
alarm becomes active (see Figure
4-2)
