User manual CHAMBERLAIN SUB300

[. . . ] Installation where the space between the gate and driveway is more than 12cm The difference between this option and the others is that the U-rail has to be fitted directly underneath on to the gate frame. If the space is extremely large, the level has to be balanced out by putting something (flat steel bar) underneath between the motor arm and the SUB100S arm. The underground drive ought generally to be installed as close to the pivotal point as possible. These safety alert symbols mean Caution ­ a personal safety or property damage instruction. [. . . ] Can be used if the box cannot be installed so that the pivot points are below one another. BEFORE YOU BEGIN Planning and precision are vital for the mounting of an underground opener, in order to ensure that unforeseen circumstances do not limit or prevent proper operation later. Wind can slow the gate down or distort it, causing a marked increase in the force required to move it. O Weight of gate: The specified weight of the gate only gives a rough indication of the output required from the drive. The function which the gate is expected to perform is also important in this connection. O Temperature: Low outdoor temperatures can make it more difficult or impossible to set the gate into motion (e. High outdoor temperatures may cause the temperature cutoff (at about 135°C) to be triggered earlier. O Operating frequency/duty factor: The drives have a maximum duty factor of around 30-50% (e. The drive is not suitable for systems with a high cycling rate (continuous operation) and such use would mean that the guarantee becomes invalid. Please remember that you will require some additional material not included in the assembly kit delivered, such as empty piping, cables, screws, plugs, etc. In order to avoid undesirable oscillation, the wing should be stable and the hinges should have as little play as possible. The more easily the gate moves, the finer should the force adjustment be made. The pivot point of the gate can be found on the mounting box = pivotal point of the arm (SUB 110 and SUB 180) (figure 5-8). Mount the arm which will later be welded to the gate and don't forget the bearing ball. SUB 100S is a special arm with rails with which the drive does not have to be positioned directly beneath the pivot point. Check the overall dimensions to ensure that you will have enough room to dig out a hole for the motor housing. The opening angle of the gate has an important influence on the position of the motor housing (figures 5-7). The piping for the electrical wiring and the drainage should be borne in mind in this connection (figure 1). The top of the motor housing should be slightly higher than the concrete surrounding it. You should aim at a strength rating of at least MG2a according to DIN standards (normal strength). Once the motor housing has been set in place, the gate can be mounted on top of it. The arm with the facilities for switching to manual operation must be welded on to the gate. [. . . ] Caution: The motor is very powerful and can cause damage to the box and the gate system if it is not switched off at the correct time. Turn the end stop so that the bolt and the fitting meet the connecting arm accurately. turn the end stop so that the connecting arm is accurately met at right angles (90°). eLECTRICAL CONNECTIONS We recommend the use of the CB1 , GOC1A or CB11 (available mid 2005) controllers.
