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 Light Curtains because this can damage the optical sensors. Avoid direct, high-pressure water
spray to clean the Light Curtains. Do not scratch the surface of the optical sensors when cleaning the Light Curtains.
• Check the mounting brackets, make sure they are securely fastened to the mounting surfaces. Tighten if necessary.
• Check that the Light Curtain cables are secured properly.

2. While the door is closing, obstruct any of the invisible light beams on the Light Curtain (the green LED on the Light Curtain Receiver will blink when
the invisible light beam is obstructed). The door should stop and reverse.
TEST THE PHOTOELECTRIC SENSORS (PRIMARY ENTRAPMENT PROTECTION)
1. With the door in the full open position place an obstruction in the path of the photoelectric sensors and press the close button. The operator should
not move.
2. Remove the obstruction and press the close button. The door should close.
ALIGN THE LIGHT CURTAINS
The Light Curtain transmitter and receiver must be aligned. When properly wired and aligned the amber and green LEDs will be ON. The amber LED is
located on the Light Curtain Transmitter and the green LED is located on the Light Curtain Receiver. If the amber and green LEDs are not on, refer to
