Troubleshooting the Conditioning System
Conditioning Problems Indicated by Error Messages
Problems that display errors are normally corrected easily and happen for definite reasons.
Usually, a stuck or out of adjustment switch (and possibly loose or damaged wires) will
cause most problems when the machine is old.
If an input fails to go off completely and still displays a dim light, the PLC will still consider
that as a good input, so look very closely.
Normally, this error occurs when Input 005 fails to receive a signal within 3.5 seconds of the
motor starting.
Here are the possible causes that can produce a BRUSH DOWN ERROR. If the Brush Lift
Motor does not run, menu to the INPUT/OUTPUT TEST and press BRUSH LIFT to check the
relay operation and voltages.
Problem
:
The brush lift motor runs but the down switch failed to operate and send a signal to PLC
Input 0CH 05.
Possible Cause
:
 Check and inspect the micro-switch. Manually operate switch to see if Input 0CH 05
will illuminate.
 Broken wire or loose connection in either the yellow 24 VDC wire or the
Violet/Yellow Wire that connects to Input 0CH 05.

This error can also happen if the Brush Up Input 0CH 04 is stuck on.
