User manual CHAMBERLAIN 770EML

[. . . ] Review all safety warnings on Page one of your garage door operator owner's manual. Ensure that the door and all its operating gear is in good condition and works easily when it is manually operated. To protect small children, install the Protector SystemTM no higher than 4"-6" (100mm-150mm) above the garage floor. [. . . ] Figure 5 shows variations which may fit your installation requirements better. Make sure the wraps and brackets are aligned so the sensors will face each other across the garage door. Fasten the "C" wraps to the mounting brackets with square holes, using the hardware shown. Drill 3/8" (9, 5mm) holes in each track and fasten securely with hardware as shown. Use bracket mounting holes as a template to locate and drill (2) 3/16" (4, 8mm) diameter pilot holes on both sides of the garage door, 4"-6" (100mm-150mm) above the floor (but not exceeding 6" (150mm). Adjust right and left side bracket assemblies to the same distance out from mounting surface. Sensor Mounting Bracket with Square Holes Mounting Bracket with Slot Attach with concrete anchors (not provided) Center each sensor unit in a "C" wrap with lenses pointing toward each other across the door. Finger tighten the wing nut on the receiving eye to allow for final adjustment. Red indicator lights in both the sending and receiving eyes will glow if wiring connections and alignment are correct. If the indicator lights are blinking (and the invisible light beam path is not obstructed), alignment is required. Adjust sensor vertically and/or horizontally until the red indicator light glows. When indicator lights are glowing in both units, tighten the wing nut in the receiving eye unit. Place an object large enough to obstruct the sensor beam in the path of the door. The garage door opener will not close from a remote control if the indicator light in either sensor is blinking (alerting you to the fact that the sensor is misaligned or obstructed). You can operate the garage door opener by disconnecting the safety reversing sensor. Failure to test and adjust the safety reverse system may result in serious injury or death from a closing garage door. [. . . ] Les détecteurs peuvent être installès indifféremment de chaque coté de la porte du garage (Figure 1), à condition que le soleil n'éclaire jamais directement la lentille de l'oeil récepteur, mais les supports doivent être connectés et fixés de telle sorte que l'oeil récepteur et l'oeil émetteur soient placés l'un en face de l'autre tel qu'indiqué sur la figure 1. Ajustez les montages de support à le même distance de la surface de montage à gauche et à droite. A power door operator, in combination with a Garage Door must be installed and maintained according to all the Manufacturer's instructions, to meet the provisions of Machinery Directive, 89/392/EWG.
