Install the Protector System

Introduction
Be sure power is NOT connected to the door operator BEFORE installing the safety reversing sensor.
To prevent SERIOUS INJURY or DEATH from closing door:
l
Correctly connect and align the safety reversing sensor. This required safety device MUST NOT be
disabled.
l
Install the safety reversing sensor so beam is NO HIGHER than 6" (15 cm) above floor.
IMPORTANT INFORMATION ABOUT THE SAFETY REVERSING SENSORS
The safety reversing sensors must be connected and aligned correctly before the door will move in the
down direction.
The sending sensor (with an amber LED) transmits an invisible light beam to the receiving sensor (with a green
LED). If an obstruction breaks the light beam while the door is closing, the door will stop and reverse to the full open
position, and the door operator lights will flash 10 times.
NOTE:
For energy efficiency the door operator will enter sleep mode when the door is fully closed. The sleep mode
shuts the door operator down until activated. The sleep mode is sequenced with the door operator light bulb; as the
light bulb turns off the sensor LEDs will turn off and whenever the door operator lights turn on the sensor LEDs will
light. The door operator will not go into the sleep mode until the door operator has completed 5 cycles upon power up.
When installing the safety reversing sensors check the following:
l
Sensors are installed inside the building, one on either side of the door.
l
Sensors are facing each other with the lenses aligned and the receiving sensor lens does not receive direct
sunlight.
l
Sensors are no more than 6 inches (15 cm) above the floor and the light beam is unobstructed.
