Problem
:
Brush Lift motor does not run when tested in the Output Test. You will need to determine
if power is getting to the motor.
Possible Cause
:
 Fuse is blown or fuse holder is bad.
 Brush bearings are causing a bind not allowing free movement up and down.
 Relay came loose in socket or has failed.
 Faulty motor.
 Bad connection to motor, check all power wiring to motor.
 PLC output 10CH 05 failed.
Normally, the Brush Up Error occurs when Input 004 fails to receive a signal within 3.5
seconds of the motor starting. Below is a list of the possible causes that can produce a
BRUSH UP ERROR.
If the Brush Lift Motor does not run, menu to the I/O TEST then OUTPUT TEST and press
BRUSH LIFT to check relay operation and voltages.
Problem
:
The Brush Lift motor runs but the up switch failed to operate and send the signal to PLC
Input 004.
Possible Cause
:
 Check and inspect microswitch, manually operate switch to see if Input 004 will
illuminate.
 Possible broken wire or loose connection at either the yellow 24VDC, or the
Green/White Wire that connects to Input 004.
 This error can also happen if the brush down Input 005 is stuck on.
