Alarm (LBA)
(Valid only for

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.
