[. . . ] After the installation a final test of the full function of the system and the full function of the safety devices must be done. This drive cannot be used with a gate incorporating a wicket door unless the drive cannot be operated with the wicket door open. Make sure that people who install, maintain or operate the gate drive follow these instructions. Keep these instructions in a safe place so that you can refer to them quickly when you need to. [. . . ] pOST FIXING BRACKET 5 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 and achieve the best dimension for your opening angle, as precisely as possible and suitable for all circumstances. If the post is not wide enough, an extension piece must be fitted to it (figure 5B). If the post is too thick, cut out part of it to make it thinner (figure 5D)or offset the gate (figure 5C). 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 on a relatively large steel plate that covers several bricks and then weld the hinge plate to it. An angle plate attached over the corner of the post is also a good means of fixing the operators. ACCESSORY TIP 1: For round posts an accessory fitting can be mounted that simplifies the setting of the A/B dimension (model 207917). ACCESSORY TIP 2: For gates swinging outwards a special fitting can be ordered. 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 as possible in order to prevent any unwanted to and fro movement. The more smoothly the gate leaf runs, the more sensitive the force adjustment must be. Note down any materials you still need and obtain them before starting to install. [. . . ] A permanent connection is formed from the distributor box via an appropriate cable. ACCESSORY TIP: Extension cable LA400-JB40 Contains: (1) 12m cable with terminals (1) Distribution box IP65 (2) Strain relief PG 13, 5 (1) Mounting material INIATIAL OPERATION Check functionality in a disengaged state with the hand on the gate. Initial electrical operation is only possible with a suitable control unit that can be purchased as an accessory. Ensure at all times that mechanical and electrical safety instructions applying to the given installation are complied with. [. . . ]
