4.4.4 Analog Interface XP4
The analog interface, an 8-core Harting interface, is used to control the output power of the laser by
analog in AD mode, and can also monitor the output light and power feedback signals of the laser. The
interface definition is shown in Table 9 below.

4.5. Introduction to Safety Interlock
Raycus‟ product is designed with a safe interlocking loop, which is a two-channel system with
output monitoring and manual reset. When the safety interlocking circuit is open, the safety circuit will
disconnect the working power of the optical module, that is, the main power supply of the optical module.
To start the main power supply, you must close the two interlocking channels (24 pin interface :17 and 20
feet short ,18 and 19 feet short). Otherwise, the main power will be turned off and the laser cannot be
turned on at this time. When one of the channels is open, the laser main power supply is impossible to
