• If −(Input value X − Reference value Y) < Lower deviation set value L − Hysteresis EPS, then QL is
FALSE.
Reference value X
Lower deviation alarm QL
Standby Sequence
Enabled Flag StbySeqFlag
Notation Example
The following notation example sets upper deviation set value H to 50°C, lower deviation set value L to
40°C, and hysteresis EPS to 10°C.
