Function
Display
If Alarm 1 is a Process Low
Alarm, the value of the
process variable at or
below which Alarm 1 will
become active (see
Figure 9-2).
If Alarm 1 is a Band
Alarm, the band of
process variable values
(centred on the setpoint)
outside which the
process variable will
cause this alarm to be
active.
If Alarm 1 is a Deviation
High/Low alarm, gives a
value above (positive
value) or below (negative
value) the setpoint. If the
process variable deviates
from the setpoint by a
margin greater than this
value, the alarm
becomes active (see
Figure 9-2).
Defines a hysteresis band
on the "safe" side of the
Alarm 1 value (see Figure
9-3).
If Alarm 2 is a Process
High Alarm, the value of
the process variable at or
above which Alarm 2 will
become active (see
Figure 9-2).
If Alarm 2 is a Process Low
Alarm, the value of the
process variable at or
below which Alarm 2 will
become active (see
Figure 9-2).
If Alarm 2 is a Band
Alarm, the band of
process variable values
(centred on the setpoint)
outside which the
process variable will
cause this alarm to be
active.
