Vertical Mounting / Linear Assembly
MUTUAL INTERFERENCE OR CROSS-TALK
When two emitter/receiver units are mounted together to obtain a greater protected height, the emitter and receiver units must
be mounted in a reverse transmitting position to prevent mutual interference or cross talk. Reception of two infrared emissions
will maintain the light curtain in a lockout condition. To go back to normal operation, switch off and on the light curtain power.
Two emitter/receiver units may be mounted together to obtain a greater protected height (see Figure 3-14). The units may be
mounted with the overlapping housings to maintain the resolution throughout the protected height.
