Hysteresis

SV

Alarm Function
Alarm output: Setting by thedeviation from the SV (except process alarm). If the input goes outside the range,
the output turns ON or OFF (in the case of High/Low limit range alarm).
Alarm type: If any alarm type (except no alarm action) is specified, the alarm type can be changed with the DIPswitch. (Default: Customer specified alarm type)
Setting accuracy: The same as control
