PLC (Programmable Logic Controller)
This section of the service manual applies only to 05TA models equipped with a Mitsubishi Fx
on
programmable controller and 10DUE operator interface. The PLC version of the 05TA enhances the
operation of the standard version by providing: Selectable automatic restart after a power failure,
choice of timed or pressure switch controlled freeze cycles, programmable blowdown adjustment,
diagnostic indicators, power failure indication, alarm relay, built in cutter delay, programmable
conveyor control contacts, estimated ice production display, and a total cycle counter.
MITSUBISHI PLC
The Mitsubishi Programmable controller contains 14 inputs and 10 outputs. The power supply for
the unit can be 100-240VAC, 50/60 Hz and is internally fused for 3A. The inputs are 24VDC
internally fused for 5-7mA. All 24VDC control wiring is blue in color and is distinguished from the
red 240VAC control wiring. The outputs are externally fused for 2A. Outputs 0, 1 and 2 are dry
contacts used for sequencing and conveyor control. Outputs 3-11 are relay type with 200/240 V
connections.
FIGURE 10-1 shows the Mitsubishi PLC installed in the 05TA. The LED indicators on the right
hand side of the Mitsubishi PLC indicate the power, run and error status of the PLC. When power is
on to the PLC and the run/stop switch is in the run position the power and run indicators will be
illuminated. If an error is indicated contact the factory immediately. The LED indicators on the left-
hand side of the Mitsubishi PLC indicate the input and output status of the PLC. If the input (X#)
indicator is illuminated, then the PLC is receiving the input. If the output (Y#) indicator is
illuminated, then the PLC is sending the output. Use of these LED’s will be helpful in
troubleshooting the machine.
