1426-i Granulator Chapter 3: Installation 13 of 37
3-3 Electrical Connections
Granulator controls (if ordered) are pre-wired before shipment. The customer is required to
provide a suitable fused supply with a disconnect switch and a cable for the incoming line to
the starter.
Refer to the technical specifications in the Appendix for horsepower, voltage, phase, and
frequency requirements to determine the size and rating of the supply cable required.
If optional controls are required, an electrical wiring diagram will be provided with the
machine in addition to the basic electrical diagram.
When the customer is providing either the motor or the starter, the machine must be wired in
accordance with the basic electrical diagram and the starter manufacturer’s instructions.
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 switch ON at main power supply.
4. Jog 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.
1. If Airveying system (optional) is fitted, 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 6. 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.
6. Allow all motors to run up to speed for at least 30 seconds.
