Five-stage control units,
400V/50Hz, three-phase with
indicator light.
Motor protection takes place
by the connection of thermal
contacts.
In the event of a fault, (operati-
on of the thermal contacts), the
internal contactor drops out and
disconnects the motor from the
power supply.
After the motor has cooled down
and the fault cleared, the mode se-
lector switch must first be switched
to the “0“ position and then back
to the required operating position
(speed position).
The control units have a connec-
tion for external control devices,
e.g. room thermostat, anti-frost
thermostat, servomotor, recirculat-
ing pump, indicator light, solenoid
valve, mixer, etc. (observe contact
rating).
