3.1.1 Sensor Interface
This interface is to connect the amplifier and distance controller.
When installing the amplifier, the shield of the amplifier should be have good
conduction with the laser head (sensor and nozzle). There a wiring terminal on the shield
of the amplifier. User can connect the terminal to the laser head. The metal sheet should
still have a good conduction with the machine. Or the capacity sensor will not work
normally.
