• INTERLOCK 1&2 IN on the interlock connectors are connected to the operating coil of the internal relay in the controller.
Connect INTERLOCK 1&2 IN to INTERLOCK 1&2 COM. 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.

• When constructing a system compatible to ISO 11553-1/ISO 13849-1, design the system for shutting off the laser power
with the following control in accordance with the standards.
• Redundant interlock system by using both INTERLOCK 1 and INTERLOCK 2 connected to safety PLC or safety
relay unit
• Redundant monitoring system by using both SHUTTER CLOSE 1 OUT and SHUTTER CLOSE 2 OUT connected to
safety PLC or safety relay unit
