User manual CHAMBERLAIN BAS300

[. . . ] This unit should not be installed in a damp or wet space. the force , as measured on the closing edge of the door , should not exceed 150N (15kg). If the closing force is adjusted to more than 150N, The Protector SystemTM must be installed. After installation and adjustment, ensure that your garage door reverses on contact with a 50mm high object placed on the floor. [. . . ] Remove the mechanical door locks in order to use the mechanical door locking system. ⷠA good earth connection must be available for connecting the drive. The BAS drive can be installed in counterbalanced up-and-over doors of different designs. C) Up-and-over door with single leaf and ceiling running rails. This accessory allows manual operation of the garage door from outside in case of power failure. The bearing (sheet metal angle) in which the revolving rods to the side of the door are guided, must be fixed extremely rigidly and must be lubricated with grease later after the installation has been completed. On the drive side the revolving rods are fitted with sleeves and are only pushed onto the drive. A small screw with an internal hex head in the sleeve secures the rod from slipping out. It is strongly recommended that the side arms are first fixed before the revolving rods are cut to the required dimension. Motor operated by a capacitor which requires a special controller. Do not lay low voltage cables in parallel. Whether the bent or straight telescopic door drive arms are used depends on the amount of space available at the side. Where the drive arm is attached to the frame depends on the door type and the amount of mounting space available. As close as possible to the point at which the door turns (swings) is ideal. This attachment should be welded to be as stable as possible since high forces are transferred to it. Straight telescopic arms operate alongside the door arms which turn the door (the arm which turns the door does not cross the path of the telescopic drive arm). There is sufficient space on the door frame to fix the drive arms to the side, top or bottom. Bent telescopic arms are fitted over the door arms which turn the door and are attached if insufficient space is available at the side to avoid contact. Both types of telescopic arm may only be pulled out to 80% of their full path (max. In the case of small doors it may be necessary to shorten the telescopic arms. The telescopic arms must be lubricated before assembly so that they function smoothly. Once the side telescopic arms are mounted the exact length of the revolving rods can be established. [. . . ] Unlatching: In a recess at the back of the plastic cover is an unlatching key. Take it out and push it into the marked opening which is also on the back of the drive. By turning it clockwise through about 180° the drive is unlatched. Latching: With the unlatching key pushed in turn it clockwise until you feel a solid resistance. [. . . ]
