Function description

The inputs of the PDP20 F 4 mag are AND-linked. The result of the logic AND operation is
expressed via safety outputs O0 and O1.
A signal output (SO) indicates the state of the sensors.
Safety outputs
There is a high signal at safety outputs O0, O1 when all the input circuits I10 ... I41 are
}
closed.
If at least one of the input circuits is open or a sensor is partially operated, the safety
}
outputs will switch to a low signal.
