Calibration of the thermal relay (only 3pH versions)

This is required to avoid motor burn-out in the event of a signifi-
cant increase in power absorption caused by a missing phase.
-

If the motor is star-powered in, 400 V, the cursor “2” should
be placed on "MIN".

-

If it is delta-driven, 230 V, the cursor "2" should be placed on
"MAX".

Even if the scale of the thermal relay does not include rated motor
absorption at 400 V, protection is still ensured in any case.
To reset, in case of an intervention of the thermal relay, press but-
ton "1".

This operation is not foreseen in the burner oper-
ation.
