8
Absolute-value
upper-limit
alarm
The alarm output is ON while the
PV is equal to or higher than the
alarm value.
9
Absolute-value
lower-limit
alarm
The alarm output is ON while the
PV is equal to or lower than the
alarm value.
10
Absolute-value
upper-limit
alarm with
standby
sequence
This alarm provides a standby
sequence.
The alarm output is ON while the
PV is equal to or higher than the
alarm value.
11
Absolute-value
lower-limit
alarm with
standby
sequence
This alarm provides a standby
sequence.
The alarm output is ON while the
PV is equal to or lower than the
alarm value.

Loop Burnout
Alarm (LBA)
(Valid only for
alarm 1 on a
Standard
Model.)
The alarm output turns ON when
the control loop is broken.
There is assumed to be a loop burnout alarm if
the control deviation (SP
−
PV) is greater than
the threshold set in the LBA Level parameter
and if the PV is not reduced by at least the
value set in the LBA Band parameter within a
specific period of time. The LBA detection time
and LBA band are set in parameters.
