The event deadband can be set when "Event No. (MODE4)" is set to No. 1 to 4, and "Event mode
(MODE4)" is set to alarm event (excluding timer alarm and FAIL alarm).
When this function is enabled, an event is activated at an event value and cleared at or below an event
value (normal range side). The difference between these values is set as deadband.

The event output relay is normally open (OFF in normal state). It turns ON at an event activation. The
event output phase allows you to reverse the relay operation.
