Motor connections
1, 2 and 3: wash speed (18-pole winding).
4, 5 and 6: extract speed (2-pole winding)
7 and 9: motor overload protector.
Motor overload protector
The motor is equipped with two self-resetting,
thermal overload protectors, situated one in each
winding of the stator. The protectors are connec-
ted in series and will trip at a temperature of
120
°
C (248
°
F) (3-phase) or 130
°
C (266
°
F)
(single phase). In the event the protectors fail
but the motor remains otherwise undamaged, an
overload protector may be mounted in the control
unit of the machine. Before making such installa-
tion check to ascertain that the windings are not
damaged. A burned out motor can be re-wound.
NOTE
Before connecting a separate overload
protector consult the local code.
Single-phase machines are also equipped with a
manually set overload protector mounted on the
extract relay in the control unit. This overload
protector protects the motor during the start-up of
extraction.
Removing the motor
•
Remove the drain valve (1) from the axle by
pulling it straight up.
•
Remove the tightening unit (2) on the rear of
the motor.
•
Disconnect the connector (3) placed
diagonally under the rear edge of the motor.
•
Remove the t wo screws (4). Pull the axle
forward slightly until the guide pins pull out of
the axle brackets. Remove the motor unit.
