4-4-2 Checking Rotation Direction
Check the correct direction of the rotor as follows:
1. Turn the main disconnect switch to “ON”.
2. Pull the Start button until the motor comes up to speed; then
push the button to stop the granulator motor.
3. Check via the appropriate window that the rotor direction
corresponds to that shown on the arrow label that is located
above the guard.
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.
