MF input (Multi-function input)
In the menu external input select: Zero, Teach, Stop laser.
NPN type: Grey MF wire connected to the negative terminal of the power supply (0V) is more than 20ms and disconnected for triggering once.
PNP model: The grey MF wire is connected to the positive electrode of the power supply (24V) for more than 20ms and disconnected for triggering once.
Note 1. Check whether the cables are correctly connected before switching on the power. In particular, the white line (analog output line) must not touch other lines.
Note 2. The blue wire (0V) and the shielded wire (mode is not grounded) are connected in the internal circuit.
However, please use the blue wire (OV) to connect the negative terminal of the power supply, and the shielded wire (analog ground) is used to simulate the output.
