Figure 60: Adjusting personnel sensor beam width
6.8.3 Adjusting the beam depth
Adjust the sensor by tilting the bottom of the sensor towards or away from the front wall of the
fume hood (Figure 61). This is to ensure that the sensors beam is at optimum angle from the
fume hood, to achieve the best field of coverage for the height of the fume hood.
The body of the Personnel Sensor can be tilted from 0° to 5° in three increments to achieve this.
