Installation Guide
Mount the transmitter and receiver facing each other. Keep the distance between 0.3 m and 15 m. Align the units for optical synchronization. Use the metal housing for stable mounting. Connect the 24 VDC supply. Wire the NPN OSSD outputs to your safety circuit. Check the ON status when all beams are received. For series connection, up to 2 units can be used. Set the switch to prevent interference.
Setup & Maintenance
No special tools are needed for setup. The optical synchronization simplifies wiring. The indicator shows power and output status. Clean the front cover with a soft cloth. Do not use solvents. Check the beam alignment after shock or vibration. Regular inspection helps keep the safety function. The response time is fast at max. 4.5 ms. The unit has reverse-connection and short-circuit protection.
