Page 9: Mounting Distance
1.4 Mounting distance Do not use the sensor system with mirrors in a retro-reflective configuration. When using more than 1 set of E3T-ST□/FT□ in adjacent areas, the emitter of one E3T-ST□/FT□ may interfere with the receiver of the other, causing the safety functions to stop working properly. Install and configure them so that mutual interference does not occur. - Page 10 Infrared LED E3T-ST1□(M)F+E39-S63 E3TT-ST2□(M)F+E39-S63 E3T-ST3□(M)F+E39-S63 E3T-FT1□F+E39-S64 E3T-FT2□F+E39-S64...
