2. While the door is closing, obstruct any of the light beams on the Monitored Light Curtain (the green LED on the Monitored Light Curtain Receiver
will blink when the invisible light beam is obstructed). The door should stop and reverse.
TEST THE PHOTOELECTRIC SENSORS (IF PRESENT IN THE APPLICATION)
1. With the door in the full open position place a solid object in the path of the photoelectric sensors and press the close button. The operator should
not move.
2. Remove the solid object and press the close button. The door should close.
3. While the door is closing, obstruct the photo beam by moving a solid object in the path of the photoelectric sensors, the door should stop and
reverse.
TEST THE EDGE SENSORS (IF PRESENT IN THE APPLICATION)
1. With the door in the full open position place a solid object on the ground in the door way. Press the close button. The operator should stop and
reverse off of the solid object.
MAINTENANCE
Periodically, check the following:
• Examine the optical sensors, ensuring they are clear of dirt and dust. If necessary, clean the front surface with a soft towel. Never use
solvents, cleaners or mechanically abrasive towels to clean the Monitored Light Curtains because this can damage the optical sensors. Avoid
direct, high-pressure water spray to clean the Monitored Light Curtains. Do not scratch the surface of the optical sensors when cleaning the
Monitored Light Curtains.
• Check the mounting brackets, make sure they are securely fastened to the mounting surfaces. Tighten if necessary.
• Check that the Monitored Light Curtain cables are secured properly.
