2.8.8 DIRECTION OF ROTATION OF ELECTRIC MOTORS
At the time of wiring, make sure that all motors rotate in the correct direction:
CAUTION: To check the direction of rotation, the motors should be
operated ONLY by impulses.
When performing these operations, follow strictly the safety rules and
stay away from any moving part inside the machine.
Remove only the panels on the LEFT HAND SIDE of the machine.
Before starting the machine, make sure that the protection panels on the
RIGHT HAND SIDE (drive) of the machine are in place.
•
main motor: the correct direction of rotation is shown by the arrow on the
flywheel; it is COUNTERCLOCKWISE for machines with FORCED
LUBRICATION and gear reducer); COUNTERCLOCKWISE for machines
with splash lubrication (see Section 1 - TECHNICAL SPECIFICATIONS),
unless otherwise specified by the direction of the arrows on the machine
(flywheel and/or motor)
•
oil pump motor (only for machines with motor-driven lubrication pump): follow
the direction of the arrow printed on the pump body. In case of mistake, the
low pressure in the circuit triggers the pressure switch, which prevents the
machine operation;
•
electric fan of main motor (only for machines designed for variable speed):
follow the direction indicated by the arrow;
•
electric fan of machine body: follow the direction indicated by the arrow;
Auxiliary motors may be installed depending on the type of machine: verify the
actual installation with reference to the technical sheet and the wiring diagrams,
Section 1 -TECHNICAL SPECIFICATIONS.
If the direction of rotation is not correct, reverse any of the two phases of the
supply cord.
CAUTION: Before starting the motors ensure that ONLY installation
personnel are present in the vicinity, and that NOBODY is in contact with
the machine.
