11. Safety Circuit Shut Down Messages
PNEG-1707 TM-Series Tower Dryer 55
Input/Output Generated Errors
The following is a list of errors that are generated with the Input/Output board located in the upper
control box.
Air System Failure
A shut down has occurred due to a air system that was installed with an integral Safety switch that was
in the unit. The air system safety connections are located in the upper control box on the terminal strip.
This can occur if this safety looses 12 VDC to terminal J1-10 on the Input/Output board. This input
is jumpered on the terminal strip when it leaves the factory and is usually installed in the field by a
qualified electrician.
Aux Load Overload
The motor overload relay has tripped on the aux load motor circuit located in the upper control box.
This can occur if this safety looses 12 VDC to terminal J1-05 on the Input/Output board. Push the
Red button on the overload to reset this error. This is caused from the motor operating with to much of
a work load, which in turn uses more current (amperage). If the problem reoccurs then check the motor
to make sure it is not being overworked. You may need to call an electrician to measure the motors
full load amps (FLA).
Aux Unload Overload
The motor overload relay has tripped on the aux unload motor circuit located in the upper control box.
This can occur if this safety looses 12 VDC to terminal J1-04 on the Input/Output board. Push the
Red button on the overload to reset this error. This is caused from the motor operating with to much of
a work load, which in turn uses more current (amperage). If the problem reoccurs then check the motor
to make sure it is not being overworked. You may need to call an electrician to measure the motors
full load amps (FLA).
Load Motor Overload
The motor overload has tripped on the load motor overload located in the upper control box. This can
occur if this safety looses 12 VDC to terminal J1-03 on the Input/Output board. Push the Red button
on the overload to reset this error. This is caused from the motor operating with to much of a work load,
which in turn uses more current (amperage). If the problem reoccurs then check the motor to make
sure it is not being overworked. You may need to call an electrician to measure the motors full load
amps (FLA).
Meter Rolls Failed
If you have the meter roll speed adjustment turned too low (not turning), this will cause this error
message. It also could indicate that you have a defective meter roll sensor, the metering roll drive
system has failed to turn or broken chain or jammed metering roll is a possibility. This can occur if the
input is not receiving a 5 volt pulse on terminal J4-04 on the Input/Output board.
Out of Grain
The dryer has run low on grain, and the out of grain timer has timed out, shutting the dryer down. The
unload auger will continue to run so it can clean out the remaining grain before shutting down.
