7-3 Circuit Diagram of Inputs
The XSTART and XFEH inputs are optocouplers with a current limiting resistor of
2.2kΩ giving a voltage of 24V in the input circuit.
For each signal X[IN] there is a separate reverse line X[IN]R via the plug
connector. From that, the following matching pairs of signals result :
The input signal STA (PIN 13) is connected to GND (PIN 12) for the “Cut on
Demand” operating mode.
For external control of cut mode, the connecting device (trigger switch, external
control) must be equipped with a 15 pin SUB-D connector.

Pin 1 - XSTART
Pin 9 - RXSTAR
Pin 2 - XFEH
Pin 10 - RXFH
