Pneg 1509 - Troubleshooting

The following is a list of possible errors that are generated with the input/output board. This board
is located in the upper main panel. This board has a LED light beside each input and output on the
board. These LED’s are a great tool in troubleshooting the board. Remember the upper left side is
12 VDC input/output and the lower right is 120 VAC input/output.
? Motor Overload
The following are messages that may show up under this shutdown. These overloads are located
in the upper panel. This means that the thermal overload has opened on that motor indicated on the
display. After pressing the red reset you should have a LED on beside the Motor Overload
terminal that was opened. This may indicate that this motor might be operating under a abnormal
work load. This condition causes the motor to pull more current (amperage) over its rated full load
amps. You made need to get an electrician to check the motors operating amperage. The name tag
on the motor will indicate the full load amps (FLA) in relationship the incoming voltage. The overload
has a normally closed set of contacts. To these contacts from the I/O board is sent 12 VDC, when
the overload opens so do these contacts. Below will indicate which terminals to check for that
particular overload shutdown. Simply check the to see if you have a LED lit up for that particular
overload. If you want to use a meter put the red lead on the terminal associated with that shutdown
and the black lead on the DC negative. The DC negative is located on the I/O board on the upper
left side labeled J2-10.
.
Primary Unload Motor Overload
This error indicates that the unload motor overload on the dryer has opened.
( J2-10 ) DC Negative
( J1-01 ) 12 Volt DC output LED should be on.
( J1-02 ) 12 Volt DC when closed (Dryer Unload Motor Overload) LED should be on.
Auxiliary Unload Motor Overload
This error indicates that the auxiliary unload motor overload on the dryer has opened.
Example: This might be a take away auger wired to the dryer.
( J2-10 ) DC Negative
( J1-01 ) 12 Volt DC output LED should be on.
( J1-04 ) 12 Volt DC when closed (Aux. Unload Motor Overload) LED should be on.
Primary Load Motor Overload
This error indicates that the load motor overload on the dryer has opened.
( J2-10 ) DC Negative
( J1-01 ) 12 Volt DC output LED should be on.
( J1-03 ) 12 Volt DC when closed (Primary Load Motor Overload) LED should be on.
