C Series Granulators Installation 15 of 53
3-5 Electrical Connections
Before operating the granulator, it is extremely important that the machine is correctly wired
into the plant power source by a licensed electrician. All electrical equipment must be
properly grounded in accordance with local and national codes to protect personnel from
electrical shock. A fusible, lockable disconnect between the plant power source and the
machine electrical cabinet is highly recommended.
To wire the granulator, run power from the plant source through a lockable, fusible
disconnect to the machine electrical control panel. From the main electrical control panel,
make the necessary control circuit connections to the jackscrew control panel, main drive
motor, and any auxiliary motors or connections.
To wire the jackscrew motors, run power from plant source through a fusible disconnect to
the machine-mounted jackscrew control panel. Wiring from the jackscrew control panel to
the safety switches, zero speed sensor, cutting chamber jackscrew and screen cradle
jackscrew is done at the factory.
Refer to the wiring diagram on page 50 for wiring connections for typical machine
applications. Check the wiring diagram supplied for any wiring that is specific to your
application.
Use the following procedure to complete the electrical connections:
a. Check to be certain that the starter heater elements correspond with the
motor requirements. If controls are not supplied, the limit switches supplied
on the machine must be wired into the circuit at the common terminal box.
b. Check that the limit switches are closed.
c. Turn the switch on at main power supply.
d. Jog the motor by pressing the Start and then the Off button. This starts
and stops the motor.
e. With the electrical power on, check that the motor rotates in a clockwise
direction at the viewing port in the belt guard. If motor rotation is correct,
continue to the next step. If rotation is incorrect, complete the following
procedure:
a. Shut power OFF and disconnect incoming power supply.
b. Reverse any two of the three power line connections to the machine.
c. Re-connect the incoming power supply line and turn ON the main power
switch to recheck motor drive rotation.
f. Press the Airveyor START button, and check the blower motor rotation.
The blower motor should rotate in a counterclockwise direction. If blower
motor rotation is correct, continue to step g. If blower motor rotation is
incorrect, complete the following procedure:
d. Shut power OFF and disconnect incoming power supply line.
e. Reverse any two of the three power line connections to the blower motor.
f. Re-connect the incoming power supply line, and recheck the blower motor
rotation.
g. Allow all motors to run up to speed for at least 30 seconds.
