  • a plurality of valves;

    a control device which receives the control information and generates valve control output information, indicating which valves should be operated;

    a plurality of physical switches, each of the switches represents one of the plurality of valves, a first group of selected switches are closed and a second group of nonselected switches are open,a logic array which receives the valve control output, the logic array compares the valve control output with the first group of selected switches or the second group of nonselected switches, the logic array generates valve operation output;

    wherein if the valve control output indicates that at least one valve associated with the first group of selected switches and at least one valve associated with the second group of nonselected switches are to be in an open position at the same time, the logic array will not send the valve operation output to the valves and will send an error message to the control unit.
