Fixing The Rack
N.B.: The BH30 gearmotor may be used with racks with a teething module of 4.
• Unlock the gearmotor (see User Guide) and move the gate into the open position.
• Place the rack on the pinion, then fasten the entire length of the rack, sliding the gate to allow access to the fasteners.
• To ensure that subsequent sections of rack are aligned correctly and maintain the correct tooth pitch, we recommend installing the rack sections with
connector pieces.
• Ensure that there is a clearance of at least 1 - 2 mm between the pinion and the rack. If necessary, adjust the height of the gearmotor or, if possible, of the rack.
• Manually check that the gate slides smoothly and without impediment.
• Fasten the gear motor definitively.

Fastening the micro-switch mechanical limit switch or magnetic limit switch
• Move the gate into the fully open position and then into the fully closed position, and fasten the limit switch
brackets onto the rack, ensuring that they are turned the right way around.
• With mechanical limit switches: R = RIGHT; L = LEFT (fig. 1).
• With magnetic limit switches, the arrows must point towards the middle of the rack (fig. 2).
ATTENTION: the magnet can be adjusted by a maximum of 8 mm by loosening the two screws.
ATTENTION: between magnet and limit switch bracket there must be a distance of 10 mm at most.
• Perform a few open/close manoeuvres then adjust the positions of the limit switch brackets so that the gate
stops 40 to 80 mm before the mechanical stop. The stopping distance depends on the weight of the gate,
friction, the control unit used and weather conditions.
• The gate must not come into contact with the mechanical stops when opening and closing.
