472-6 Construction of SystemThe following figure shows the construction sample of the system.ABCDABCDABCDBCDauw yqiotre1!No. Description Installation and control sampleq Laser marker head -w Laser marker controller -e PC for laser marker setting/monitoring -r Protective enclosure -t Laser protection shutter for work piecegatewayConstruct a control system which will separate (cut off) the laser beamsor shut off the laser power when it is opened.y Emergency stop button Construct a control system for shutting off the laser power source whenit is opened.u Safety switchi Door for the maintenanceo Safety relay unit or safety PLC, etc. Connect both INTERLOCK 1 (X16, X17) and INTERLOCK 2 (X18,X19) of the laser marker to the devices t to i using the relay outputterminal of the safety relay unit or the safety PLC.Besides INTERLOCK terminals, it can also be connected to other I/O signalssuch as LASER STOP terminals with the devices t to i depending onthe control specifications.1) Laser radiation warning light To indicate the laser marker status, connect the output signals such asALARM OUT (Y15) or LASING OUT (Y20) to the light.1! Dust exhauster Place the intake vent of the exhauster as close as possible to themarking position of the work pieces.ワㄐㄕㄊㄆ• INTERLOCK terminals (X16, X17 and X18, X19) are connected to the operating coil of the internal relay in the controller.Connect INTERLOCK (+) and INTERLOCK (-) in the I/O terminal with the non-voltage contact (dry contact) such as arelay or a switch. Do not connect with the voltage contact such as a transistor.ンㄆㄇㄆㄓㄆㄏㄆ• When constructing a system compatible to ISO11553-1/ISO13849-1, construct the redundant interlock system by usingboth INTERLOCK 1 (X16, X17) and INTERLOCK 2 (X18, X19) connected to safety PLC or safety relay unit to shut off thelaser power supply in accordance with the standards.ME-LPGS-SM-8
