The control package includes a PLC controller which is
programmed for the drying cycle previously discussed. The
display board indicates the machine status, heater operation
and alarms. See section on start up for details.
Below are descriptions of the inputs and outputs of the PLC
which are used for trouble shooting. A lit LED indicates the
input or output is actuated. All inputs are 12 volts AC and all
outputs are 110 volts AC and 15 v DC to the heater relays.
Refer to the electrical schematic for more detail.
