User manual CHAMBERLAIN HC300MLS-ML2

[. . . ] The full protection against potential squeeze or entrapment must work direct when the drive arms are installed. Any entrapment possibility by the moving wing between wing & walls must be secured with safety edges or IR-sensors. Please remove any locks fitted to the gate in order to prevent damage to the gate. After the installation a final test of the full function of the system and the full function of the safety devices must be done. [. . . ] gATE STOPS A SWING GATE NEEDS A FIXED GATE STOP IN BOTH THE OPEN AND CLOSE POSITIONS. Operating a gate without fixed limit stops results in poor performance. It is often dangerous, leads to premature wear and voids your warranty! pOST FIXING BRACKET Choosing the correct location for the post fixing bracket has a decisive impact on the subsequent functioning of the system. It determines the distance between the motor's centre of motion and the gate's centre of motion and hence the opening angle. Do not underestimate the effect that these dimensions have on correct functioning and running. Try to achieve the best possible dimension for your opening angle that is suitable for all circumstances. If the post is not wide enough, an extension piece must be fitted to it. If the post is too thick, cut out part of it to make it thinner or offset the gate. To obtain ideal dimensions, it may be necessary to shorten or lengthen the supplied hinge plate. In the case of gates that are to be custom made, if the gate hinges are fitted on the posts appropriately, it is possible to influence dimensions A and B. Before the final mounting dimensions are determined, you should always check whether or not there is any possibility that the corner of the drive mechanism will hit the post as the gate swings. iNSTALLATION: The drive mechanism exerts considerable force against the post. Usually, acceptable mounting dimensions are obtained if the supplied hinge plate is welded directly onto the post. In the case of thick stone or concrete posts, the hinge must be welded to a base plate and attached so that the plugs cannot work loose during operation. Heavy-duty plugs where a threaded rod is bonded into the masonry stress-free are more suitable for this purpose than steel or plastic straddling plugs. In the case of brickwork pillars, bolt a relatively large steel plate that covers several bricks on to it and then weld the hinge plate to it. An angled plate attached over the corner of the post is also a good means of fixing the operators. The gate must run evenly and smoothly and must not stick at any point. Remember that the ground level may be several centimeters higher in winter. The gate must be stable and as free of backlash in order to prevent any unwanted movement. The more smoothly the gate wing runs, the more sensitive the force adjustment must be. [. . . ] Push the released drive onto the fittings and secure it by using the supplied bolts and rings. 80 cm long and is laid in a curve to the controller or a watertight distribution box located above ground. An approved cable is permanently installed from the distribution box onwards. The capacitor can be connected inside the distribution box or in the controller. [. . . ]
