5. After mounting the bracket base, attach the photoeye and bracket clamp. Tighten the two bracket
clamp screws (ITEM B) to secure the photoeye, but leave them loose enough for the photoeye to
swivel using the ball joint during the alignment process.
6. Sensitivity Adjustment - Adjust sensitivity using potentiometer R1
(shown to the right) at the top left of the circuit board. Use the
markings as a guide based on the distance between the sensor and
reflector:
• 5-20 ft: Point the dial at the 5-20 ft marking
• 20-30 ft: Point the dial at the 20-30 ft marking
• 30-60 ft: Point the dial at the 30-60 ft marking
If you have trouble aligning the sensor or if you are concerned
about rain, snow, or fog obstructing the IR beam, you can increase the sensitivity by adjusting the
potentiometer clockwise.
Configuration - After setting sensitivity, check DIP switches SW1 and SW2, and jumper JP1 to ensure
proper setup (refer to Configuration Table on PAGE 9 and Wiring Diagrams on PAGES 10-12).
Adjusting sensitivity and configurations might be harder once the photoeye is aligned, as the back
cover may not be easily accessible.
Stealth Mode – Enable Stealth Mode by turning ON Position 2 on DIP switch SW2. In Stealth Mode,
LEDs turn off after 30 seconds if the sensor is aligned and unblocked, but turn on when obstructed,
turning off again after 30 seconds. This mode is helpful for hiding the sensor from passers-by and
vandals, especially at night. It can be used in any setup and doesn't affect other functions.
After final adjustments are made, replace the back cover ensuring the gasket is present, and tighten
the screws.
