is protected against overheating by thermal overload releases or a motor
overheating protection unit.
When using thermal overload releases, the motor has to be protected as fol-
lows:
–
during operation by a release set to the rated current and
–
during start-up by a second release set to 1.8–2 times the rated current.
The release set to the rated current must be bridged during start-up.
Overheating protection is only possible if PTC thermistors are built into the mo-
tor winding.
Note:
•
The temperature feelers must be connected to a commercial tripping device.
•
External voltage higher than 2.5 volts must not be applied to the connection
terminals of the temperature feelers.
•
When testing for continuity, use an ohmmeter and not a test lamp.
4.1.4 Direction of rotation of the bowl
Fig. 76
•
Fill the drive chamber with oil up to
the half way mark on the sight glass.
•
Switch on the motor.
The bowl must rotate in clockwise direction when looked at from above.
Fig. 77
The direction of rotation of the bowl is
correct when the drive belt rotates
clockwise (check through the sight
glass in the frame).
When the direction of rotation is incor-
rect the motor connections must be
reversed by an authorised specialist.
