Electrical Instructions

Electrician

RMS is happy to work with your electrician to answer any questions pertaining to wiring the motors and other electrical components on your mill. Our engineers can work with the electrician to make sure everything functions properly. Following are some important electrical guidelines.

Main motor start up sequence:

  • Consult the wiring legend on the motor as in the photo below.

Motor nameplates include wiring legends. Alt text Alt text

Motor rotation:

• When looking at the left side of the machine, the motor should be spinning in a counter-clockwise rotation. This is also true of the right side of the machine.

Rolls should spin inwards when motors are spinning counter-clockwise.

Roll spinning properly

IMPORTANT:

Any electrical work should be completed only when power sources to each motor have been disabled and motors have cooled down!

Check and clean motors at least monthly to ensure they are free from contaminates. This ensures the motors are able to adequately cool themselves and avoid overheating.

Interlocking

Interlocking the electrical components on a roller grinder is one of the most important steps when installing a machine.

You must interlock the main grinding motors to the downstream take away equipment, an auger or chain disk conveyance system for example, to prevent them from starting if those downstream components are not energized.

This is critical to ensure that the roller grinder shuts off if the one of the components downstream stops running for any reason.

Amp Meter Box

We highly suggest you install an amp meter box on your mill to prevent over amperage of motors, loading to motor failure, or overload.
