Page 8: Scope
DIN 7984 Safety Intended use Safety light grids of the PSEN op4H-SL Series are electrosensitive protective equipment of the 4. They are used to protect personnel and systems. The safety light grids are designed securing hazardous areas within buildings and securing access within buildings with a resolution of 24 mm. -
Page 9: Safety Regulations
In order to achieve the re- quired safety level for the overall plant/machine, define the safety requirements for the plant/machine and then define how these must be implemented from a technical and organ- isational standpoint. Operating Manual PSEN op4H-SL Series 1004305-EN-01... -

The protected area is covered by infrared light beams, which are emitted from the transmit- ter to the receiver. The protected field thus produced is able to detect an opaque object. The control and monitoring of the transmitted and received infrared rays is performed by microprocessors. Operating Manual PSEN op4H-SL Series 1004305-EN-01... -
Page 11: Automatic And Monitored Start
If an error occurs, the OSSDs remain in the OFF state. The state can be returned to the ON state only after a successful restart [ of the safety light grid. The safety light grid in the PSEN op4H-SL Series offers the following functions: Automatic start Monitored start EDM (when connected to a relay with positive-guided contacts) -
Page 12: Manual Restart
If a malfunction is de- tected, the safety light grid switches to a safe state and stops the connected machine. This check is carried out each time the OSSD is triggered and before restarting. Operating Manual PSEN op4H-SL Series 1004305-EN-01... -
