• 1 copy operating instructions photoelectric safety sensors, reference no. 704857. If one of the above-mentioned components is missing or damaged, please contact one of the ifm branch offices. 4 Functions and features transmitter (T) receiver (R) P = protected area; I = protected area width (range) H = protected area height The OY95xS safety light grids are multi-beam optoelectronic protective devices to IEC 61496 and consist of one transmitter and one receiver. -
Page 8: Function
5 Function The protected area (P) is generated between the transmitter and the receiver and is defined by the protected area height (H) and the protected area width (range) (I). The protected area height is the height protected by the safety light grid. It depends on the design (→... -

Application example: A = hazardous area S = minimum safety distance 6.3 Installation of the safety light grids These versions of OY95xS safety light grids are suitable for access prevention for entire bodies. They must not be used for the protection of hands or body parts! The minimum safety distance (S) is determined using the following formula: S = 1600 (t + t... -
Page 12: Fixing And Optical Alignment
6.5 Fixing and optical alignment Correct alignment of the transmitter and the receiver is decisive for the proper function of the photoelectric safety sensors. ► Install the transmitter and the receiver using the supplied mounting accessories so that they are exactly opposite each other. 6.5.1 Optical alignment T = transmitter;... -
Page 13: Distance Of Reflective Surfaces
6.6 Distance of reflective surfaces Reflective surfaces close to photoelectric safety sensors can disable the safety function of the system. The minimum distance (D) depends on the protected area width (I) taking into consideration the projection and receiving angles. The minimum distance (D) between reflective surfaces and the protected area (P) must be observed. -

Page 18: Operating Modes
8 Operating modes The different operating modes of the OY95xS series safety light grids can be set via the respective connections on the 8-pole plug of the receiver. Operating modes Connections pin 4 pin 5 pin 6 A Automatic K1_K2 SEL_A SEL_B L + L... -
Page 19: Automatic Operation
8.1 Automatic operation If the safety light grids are used in the automatic mode, monitored start is not possible. The safety light grids automatically return to operation with clear protected area, the outputs (OSSDs) are activated. Verify if this is compatible with the risk analysis of your machine. In the automatic mode the OSSD1 and OSSD2 outputs follow the status of the safety light grids: Protected area clear... -
Page 20: Connection Of External Feedback Contacts
8.3 Connection of external feedback contacts External feedback contacts can be integrated in the automatic or manual operating mode. The feedback contacts have to be connected in series between the operating voltage and K1_K2 (→ 8 Operating modes / table, fig. B and D). 8.4 Internal test function Type 4 safety light grids continuously perform internal tests. -

Page 24: Operation
10 Operation 10.1 Switching state of the outputs The safety light grids have two outputs (OSSDs) on the receiver; the status depends on the condition of the protected area. Any short circuits between the outputs or between an output and the operating voltage (24 V DC or 0 V DC) are detected by the safety light grids as a fault. -
Page 25: Functional Test Of The Safety Light Grids
10.2 Functional test of the safety light grids Check the proper function of the safety light grids before work starts. For the functional test an opaque test object has to be used. ► Interrupt the light beams with the test object.
