• 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ㄆㄇㄆㄓㄆㄏ㄄ㄆ
• 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.
