Short-Circuit Protection Feature (SCP)
RightSight photoelectric sensors provide short-circuit protection (SCP) on the output leads. This feature is intended to protect the sensor from damage in the event that the output load is shorted to ground. If this condition does occur, the SCP will activate and the orange and yellow LEDs will flash (for AC/DC models only the orange indicator will flash) until the source of the short isremoved(powermustberesetforAC/DC models). The SCP limits are set to 100mA over the entire voltage range.

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.
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 r emoving 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.
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

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.
