Review the items on the Settings Menu screens (items 1 through 15 shown above) and
make any adjustments you feel necessary. The PLC has been programmed with factory
defaults that should work as a starting point in most circumstances. To access the
settings, go to the Main Menu, select Settings, and then select Icemaker. From that point,
scroll through the settings one at a time and make any necessary changes. The very last
screen in this string of screens will allow you to restore the original factory settings
(NOTE: all previous settings will be lost if you restore to factory defaults).
Starting the Modular System
To start the system, any modules you want to operate need to be put in the Auto mode via
the pushbutton on the Modular unit, or with the operator interface as shown by pressing
the Auto button. Once the desired modules are in the Auto mode, go to the MCS screen
and press the Master button. The PLC will sequentially start each Module in a harvest
cycle after which it will go into a freezing cycle. The modules start sequentially in the
order determined by the ID switches in the “Configuring a New System or Module”
section. The Modules will now continuously freeze/harvest until the Master switch is
turned off, the Bin Level Switch (see wiring diagram) signals the system to stop, or the
individual module is turned off via the interface on the Master Panel or the Mode Switch
on the Module. Once Off is selected, the Module(s) will continue to run until it(s)
freezing cycle and harvest cycle is complete. If it is necessary to stop the machine
immediately, push the red emergency stop button (see wiring diagram).
