20.3 CHECKING THE DIRECTION OF ROTATION
- Check that all fixed protections are in their proper place.
- Power the control panel using the line switch Ref. 1 Fig. 25.
- Open the rear panel Ref. 7 Fig. 25.
- Check that there are no alarm signals on the control board.
- Check the direction of rotation (
according to the arrow on the coupling casing or on the motor Ref. 3 Fig. 25) by pressing the “Start” button
Ref. 2 Fig. 25, and immediately after the emergency shutdown Ref. 4 Fig. 25. If the direction is incorrect, invert the two electrical
connection wires (phases). If the direction of rotation is correct, the oil level Ref. 5 Fig. 25 must drop after 4 - 5 seconds of operation.
Moreover, it is very important to check the direction of rotation of the fan (indicated by the arrow on the latter), Ref. 6 Fig. 25.
ALL OPERATIONS ON THE ELECTRICAL SYSTEM, EVEN IF MINOR, MUST BE PERFORMED BY PROFESSIONALLY
QUALIFIED PERSONNEL
