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 can not be
turned on at this time. When one of the channels is open, the laser main power supply is impossible to
start until the other channel is open, and then the two channels are closed before the laser main power
supply can be started.
If the interlock is closed (the stop button is also released) and there is no error alarm, press the start
(LASER) button to start the main power supply, and the ‘main power has been started’ pin of the external
interface will have a high-level output. When the security interlocking circuit is open or the error is
detected, the main power supply of the optical module will be turned off, and the ‘main power supply has
been started’ signal of the interface will become low level. The detected ‘error state’ is latched and the
on-board relay opens the manual reset loop with monitoring until the error is cleared, thus preventing the
laser from being restarted. If errors such as short circuit between interlocking channels or short circuit of
start (LASER) button are detected, the safety loop can not be reset before the error is cleared.
