Construction of interlock system
For operating this product, construct the protective enclosure enclosing the range of the laser radiation for protecting
the exposure caused by the reflection of the laser radiation from the marking object or the surrounding objects, and also
construct the interlock system. The following figure shows the construction sample of the interlock system.

• Interlock input is connected to the operating coil of the internal relay in the controller unit.
Connect interlock inputs 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.

• For LP-Sxxx-SF/LP-Sxxx-LS1 type, when making a system compatible to ISO 11553-1 / ISO 13849-1, construct the
redundant interlock system by using interlock 1 and 2 connected to safety PLC or safety relay unit to shut off the laser
power supply in accordance with the standards.
• When primary AC power supply of the system is performed as a safety measure, process AC power cable to set the
switch as follows.
