winding. The thermoswitch is tripped as soon as the max. permissible winding
temperature has been reached.
The actuator is stopped and the red indication light on the local controls is illuminated.
The motor has to cool down before the operation can be resumed.
Version with thermoswitch (standard)
The actuator can be controlled again once the motor has cooled down (red indication
light goes out).
Version with thermoswitch and additional thermal overload relay within the
controls (option)
The operation may only be resumed once the fault signal (red indication light) has
been reset. The fault signal is reset via the overload relay integrated in the actuator
controls. Therefore the controls have to be opened at the cover and the relay held
down. The relay is located on the contactors.
Version with PTC thermistor (option)
The operation may only be resumed once the fault signal (red indication light) has
been reset. The fault signal is reset via selector switch position Reset of the local
controls.
