Alignment of Wired Infrared Safety Sensors
TO AVOID POSSIBLE SEVERE OR FATAL
INJURY, KEEP PEOPLE AND OBJECTS
CLEAR OF THE MOVING DOOR ARM.
IMPORTANT:
THE SAFETY SENSOR SENDS AN INVISIBLE BEAM OF LIGHT FROM THE
SENDING UNIT TO THE RECEIVING UNIT ACROSS THE PATHWAY OF THE DOOR. THE
OPENER WILL NOT OPERATE UNTIL THE SAFETY SENSORS ARE CONNECTED TO THE
OPENER AND PROPERLY ALIGNED. IF THE INVISIBLE BEAM OF LIGHT IS OBSTRUCTED,
AN OPEN DOOR CANNOT BE CLOSED BY THE TRANSMITTER OR A MOMENTARY
ACTIVATION OF THE WALL STATION UP/DOWN BUTTON. HOWEVER, THE DOOR MAY
BE CLOSED BY CONTINUOUSLY HOLDING YOUR FINGER ON THE WALL STATION
UP/DOWN BUTTON (CONSTANT PRESSURE) UNTIL THE DOOR TRAVELS TO A
FULLY CLOSED POSITION.
The safety sensors must be aligned by moving the sending and receiving units until the alignment
lights turn on. The wing nuts on the sensors can be loosened and the sensors slid in and out as
required.
If you have difficulty aligning sensors, check
that both brackets are mounted at the same
height. (See Section 11) and re-mount as
necessary. Additional minor adjustments can
be made by slightly bending mounting
brackets.
Once alignment lights come on, tighten all
wing nuts and mounting screws.
Note: The Red LED (on the Transmitter module) will be ON whenever the sensors are powered.
The Green LED (on the Receiver module) will be ON steady when the sensors are properly aligned.
If the Green LED is unsteady, flashes or dims, realign the sensors or check for obstructions.
