47 / 98 page  29 SECTION 10 Installation !WARNING Install the sensor system so that it is not affected by reflective surfaces. Fail- ure to do so may hinder detection, resulting in serious injury. 10-1 Reflective Surface Interference A reflective surface adjacent to the detection zone can deflect the optical beam and may cause an obstruction in the zone not to be detected. The reflective surface may be part of the machine, mechanical guard or work- piece. Therefore, a minimum distance (d) must exist between the reflective object and the center line of the detection zone. The Test procedure (Appen- dix B) must be used to test for this condition. In this picture, the interruption is clearly detected. The reflective object is out- side of the beam angle. Operating range R: is the effective working distance of the MS4800 system, from the transmitter to the receiver. EAA: is the effective aperture angle of the Safety Sensor. it is ±2,5° for MS4800 system distance d: is the minimum distance to a reflective surface. This distance must be bigger than: dmin MS4800 system = tan(2,5°)×R Be aware that reflective surface interference may also appear above and below the sensing field. Operating range R Transmitter Receiver Interruption Approach direction Reflective surface EAA d = distance to reflective surface |
