9.2 Heater AUMA multi-turn actuators have a heater installed as standard. To prevent
condensation, the heater must be connected.
9.3 Motor protection In order to protect against overheating and impermissibly high temperatures
at the actuator, thermoswitches are embedded in the motor winding. The
thermoswitch is tripped as soon as the max. permissible winding
temperature has been reached.
9.4 Remote position transmitter For the connection of remote position transmitters (potentiometer, RWG)
screened cables must be used.
9.5 Fitting of the cover After connection:
.
After completion of the power supply connection, insert the socket carrier
(51.0) into the plug cover (50.0) and fasten it with screws (51.01).
.
Clean sealing faces at the plug cover and the housing.
.
Check whether O-ring is in good condition.
.
Apply a thin film of non-acidic grease (e.g. Vaseline) to the sealing faces.
.
Replace plug cover (50.0) and fasten bolts evenly crosswise.
.
Fasten cable glands with the specified torque to ensure the required
enclosure protection.
