Configuring the Sensor
All ClearSight RightSight models contain a single turn adjustment knob on the
top cover. This knob controls the sensitivity of the sensor to the light being
reflected back toward it by the reflector. The factory default setting is at
maximum sensitivity
1. Visually align the sensor on the reflector until the yellow output LED turns
ON (light operate models) or turns OFF (dark operate models). Also verify
that the orange margin LED turns ON.
2. To be certain that the beam is centered, it is required to sweep the sensor
in both the horizontal and vertical planes and determine at what position
the output indicator goes ON and then goes OFF. Set the sensor midway
between both positions. The visible red beam of the sensor will be visisble
on the reflector and can be used as an alignment aid.
3. Break the beam with the object to be detected and check if the output
indicator turns ON (dark operate models). If this does not occur, turn down
the sensitivity adjustment until it does. Restore the light beam by removing
the object and check if the indicator turns OFF again and that the orange
margin LED comes ON. If this does not occur, increase the size of the
reflector or decrease the distance between the reflector and the sensor.
In some applications it may be necessary to slightly angle the sensor and
reflector into the target to minimize false triggering of the sensor output.
Depending on the type of clear object to be sensed, a sensor with coaxial
optics like the ClearSight 10,000 or ClearSight 9000 models may be required.
