LOAD, FIRING, DIAGNOSTICS & RATINGS

AC 51 resistive or low inductance loads

CATEGORY OF USE

AC 55b infrared lamps

(Tab. 2 EN60947-4-3)

AC 56a: transformer loads

PA - Load management by adjusting the ﬁring angle (only

conﬁguration single-phase or delta open)

ZC - Zero Crossing with constant cycle time (settable in range

1-200sec)

Trigger Mode

BF - Burst Firing, or D.O.T. with variable cycle time optimized min.

HSC - Half Single Cycle corresponds to Burst Firing that includes ON

and OFF half-cycles.

Useful for reducing ﬂicker with short-wave IR loads (applied only to

single-phase resistive or 3-phase 6-wire open delta loads).

V, V

: Voltage feedback proportional to RMS voltage value on load

(useful to compensate possible variations in line voltage).

I, I

: Current feedback: bound to RMS current value on load to com-

Feedback Mode

pensate variations in line voltage and/or variations in load impedance.

P: Power feedback: proportional to real power value on load (useful

to keep constant values of electrical power assigned regardless of

load impedance or line voltage variations).

FUNCTION

Detection of shorted load circuit,

Diagnostics

absence of line voltage, HB alarm (partial break of load)

OPTIONS

- Timed Soft-Start ﬁring ramp, with or without peak current control

- Soft-Start ﬁring ramp (speciﬁc for infrared lamps)

Options

- Timed shut-off ramp

- Limitation of RMS current in load

- 0-90° Delay-Triggering for ﬁring inductive loads in ZC and BF/DOT modes.

- SCR in short circuit (presence of current with OFF control)

- Absence of SCR current when under load.

- Overtemperature alarm

Current read

Diagnostic

• HB alarm: interrupted or partially interrupted load

• Automatic calibration of HB alarm setpoint starting from current value in load

• Alarm for load in short circuit or overcurrent

Voltage read

• No line voltage
