AEC Colortronic MTF 2000 Series Granulator - Manual (Page 13)

Tangential Feed Granulators Installation 13 of 39
3-2 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.
The standard granulator is pre-wired to the remote motor control enclosure before shipment
and the only wiring required is a main power line to the electrical panel.
Refer to the wiring diagram on page 37 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:
1. 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.
2. Check that the limit switches are closed.
3. Turn the switch on at main power supply.
4. Jog the motor by pressing the Start and then the Off button. This starts and stops the
motor.
5. 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.
6. 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 7. If blower motor rotation is incorrect, complete the
following procedure:
a. Shut power OFF and disconnect incoming power supply line.
b. Reverse any two of the three power line connections to the blower motor.
c. Re-connect the incoming power supply line, and recheck the blower motor
rotation.
7. Allow all motors to run up to speed for at least 30 seconds.
