Introduction
Introduction
The “B” electronic control is composed of the electronic control unit and the control fuse board with wiring harness. Only an authorized person should look inside the machine. First TURN OFF POWER, open lid and remove any cover present. The components are described below.
Electronic Control Unit
This portion of the control contains the “intelligence” – the
The control unit monitors and responds to input, gives information about the status of the washer and monitors and responds to inputs from the user interface (keypad). The control provides signals to the control output unit, which in turn operates the components that control the machine functions. This is located behind the machine control panel.
Control Output Fuse Board
This portion of the control contains the power supply for the control unit, and also the switching devices which power the components in the machine, all of which are on the output PC board. The switching devices are controlled by the control unit, and are solid state.
Harnessing
Wiring harnesses are modular – harnesses common to various configurations are similar, while those specific to a certain configuration can be added. There are harnesses for inputs to the control unit, for outputs from the control power/output unit to the machine components, and for the main incoming power to the control power/output unit.
Communications
The control will accept communications with a Card Reader in order to perform vending transactions when a card is inserted to pay for cycles. The Card Reader can also allow the owner to program and collect audit information.
For detailed information on the Card Reader Communications, refer to the third party Card Reader manufacturer.
