

Is the overload set properly according to the motor

amperage found in the motor data tag? See Tech
Note 8557.



Are the running amps balanced according to Tech

Note 2297?



The wires of the fan overload are connected to P3

terminal. Check wiring and P3 terminal connector.



Is ductwork installed causing an air restriction?



If the machine has a blower drive installed, install

an LCP or HIM to read the fault log of the drive.



Megger the motor

Remote Stop Failure

Xe Software Logic for R & RS machines:

Will occur if the remote start/stop option is enabled, the
remote stop button remains open and either start
button is pressed. The remote stop switch is normally
closed.

Recommended Checks



Ensure the connection in P3 terminal of the remote

stop circuit is closed: 0 volts DC across the 2
