AUX LOAD OVERLOAD
Use a voltmeter on the following terminals:
Black probe - unused terminal where the network connections are terminated (Input/Output Board)
Red probe (J3-09) 12 VDC output
Red probe (J2-10) 12 VDC when closed

REAR DISCHARGE
This indicates that the lid on the grain discharge box has opened. This could be caused by the grain not
being taken away fast enough or not at all. Checking the grain take away system will usually fix this
problem. There is 12 VDC sent out from the Input/Output board to the mercury switch located under the
discharge box lid and must return to the board or this error will appear.
Use a voltmeter on the following terminals:
Black probe - unused terminal where the network connections are terminated (Input/Output Board)
Red probe (J3-07) 12 VDC output
Red probe (J2-05) 12 VDC when closed
USER SAFETY
A shut down has occurred due to a user installed safety switch that has opened. The connections to this
are on the terminal strip located in the upper panel. There is 12 VDC sent out and must return or this
error will appear. This input is normally jumpered when it leaves the factory on the terminal strip. If in use
this has normally been installed by an electrician.
