• I/O cards A11 and A12
The I/O cards are controlled by the CPU card via a serial interface. The
I/O cards feature outputs, which, via the communication cards in the
rear electric box, control various machine functions, such as the wa-
ter valves, heater connection and drain valve. On the input connection
blocks, it is possible to connect signals for control of e.g. the detergent
supply.
The cards also have inputs for emergency stop and door lock ACK.
