using the relay output
terminal of the safety relay unit or the safety PLC.
Besides INTERLOCK terminals, it can also be connected to other I/O signals
such as LASER STOP terminals with the devices

the control specifications.
1)
Laser radiation warning light
To indicate the laser marker status, connect the output signals such
as ALARM OUT (Y15), LASER SUPPLY OUT (Y20) or LASING OUT
(No.40) to the light.
1!
Dust exhauster
Place the intake vent of the exhauster as close as possible to the
marking position of the work pieces.
ワㄐㄕㄊㄆ
• INTERLOCK terminals (X16, X17 and X18, X19) are connected to the operating coil of the internal contactor in the
controller. Connect INTERLOCK (+) and INTERLOCK (-) in the I/O terminal with the non-voltage contact (dry contact)
such as a relay 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 using
both INTERLOCK 1 (X16, X17) and INTERLOCK 2 (X18, X19) connected to safety PLC or safety relay unit to shut off the
laser power supply in accordance with the standards.
