Function description
0
Relay, logic output: alarm active
on load current level lower
than setpoint during the
ON time of the control output
1
Relay, logic output: alarm active
on load current level higher
than setpoint during the
OFF time of the control output
2
Alarm active if one of functions 0 and 1
is true (OR logic between 0 and 1) (*)
3
Continuous heat alarm (**)
7
Continuous cool alarm (**)
(*) minimum setting is fixed at 12% of amperometric full scale
(**) As type 0 without reference to cycle time
Notes:
- The HB alarm is disabled if assigned to a rapid output (except codes 3 and 7)
- When the CT input is present, faceplate LED OUT3 always indicates the state of the HB alarm.
