If the rotation direction is correct, the granulator is ready to use. If
the rotation direction is incorrect, reverse the rotor direction as
follows:
!!Warning!!
A LICENSED ELECTRICIAN must carry out this operation.
1. Disconnect and lockout the power to the machine at the
incoming power source. If the disconnect is not lockable,
remove the fuses.
2. Reverse any two of the three power line conductors to the
machine. If there is more than one motor on the machine and
only one is turning in the wrong direction, reverse any two of
the three line conductors at the overload relay for that motor.
3. Unlock the power and switch the electrical disconnect switch
to “ON”. (Replace the fuses if necessary.)
4. Re-check the rotation direction of the motors.
4-4-3 Test the Interlock Switches
With the cutting chamber and screen cradle closed and power On,
perform the following tests:
1. Push the start button to start the granulator.
2. Retract the screen cradle interlock actuator screw by turning it
counterclockwise. Make sure that the end of the actuator screw
is visible and clear of any contact. The granulator should stop.
3. If the machine continues to run, turn off and lockout the power.
4. Have the electrician check the interlock switch on the screen
cradle to correct the malfunction.
5. If necessary, engage the screen cradle interlock actuator screw.
Having completed the above procedures, close the control panel.
Unlock power or return the fuses in the supply panel, turning the
disconnect switch to “ON”. Pull the start button and release only
when the motor has started, then check again that the rotor is
turning in the correct direction.
