Figure 14. Installation of Multiple Systems
WARNING: Multiple Pairs of Sensors
Do not connect multiple pairs of sensors to one Interface Module (for example, IM-T-9A/-11A) or
otherwise parallel OSSD outputs. Connection of multiple OSSD safety outputs to a single device could
result in serious injury or death.
WARNING: Scan Code
In situations where multiple systems are mounted closely together, or where a secondary emitter is in
view (within ±5°) and within range of an adjacent receiver, the adjacent systems must be configured for
different Scan Codes (one system set for Scan Code 1 and the other for Scan Code 2). If not, a receiver
may synchronize to the signal from the wrong emitter, reducing the safety function of the light screen.
This situation is discovered by performing the trip test. Failure to follow these instructions could result in
serious injury or death.
