Maximum conduction value in this phase can be limited by means of the PS.Hi parameter.
If requested, MUST be activated only with Hd.6=0 (the required Hd.6 value can be set only after calibration).
In case of HSC firng mode, the Heater Break alarm teach-in function doesn't calibrate at 5%, 3%, 2% and 1% in order to avoid high peak
currents due to the low impedence at very low temperature of the IR lamp filament.

Description of functions
Val
Relay, logic output: alarm active at a
0
load current value below set point for
control output ON time.
Relay, logic output: alarm active at a
1
load current value above set point for
control output OFF time.
Alarm active if one of functions 0 and 1
2
is active (OR logic between functions
0 and 1) (*)

Continuous heating alarm

Continuous cooling alarm
Default:
SINGLE-PHASE LOAD: each A.HbX refers to
its respective phase
3-PHASE LOAD: single reference setpoint
A.Hb1 and OR among phases 1, 2 and 3.
+ 8 HB reverse alarm
+ 16 relates to single setpoints and singled
phases WITH 3-PHASE LOAD

alarm is associated.
NB: In case of 3-phase load, you can set a different value for parame-
ter A.Hb1, A.Hb2, A.Hb3 for each zone (ex.: to control an unbalanced
3-phase load)
