MOTOR AND RACK INSTALLATION
The rack must be fixed at a certain height with respect to the motor base.
This height can be varied thanks to the slots on the rack.
The height needs to be adjusted so that the gate does not rest on the reduction unit traction
gear (Fig. 5, 6).
Holes with a diameter of 7 mm should be made to fix the rack into the gate, and they should
be threaded using a M8 type screw tap.
The pinion must have a clearance of 1 to 2 mm with respect to the rack.
LIMIT SWITCH ADJUSTMENT
To adjust the assembly: release nuts G, after establishing the direction of movement of
cam H for opening and closing, position the two limit switches, F, by turning knobs P and
judging by sight.
After checking for correct operation of the two microswitches, precisely adjust their positions
so that the gate will stop in the desired position during opening and closing. Then fasten
nuts G.
N.B. The standard limit switch is used for gates of a max. Iength of 13 meters.
If the gate is longer, «Special» limit switches for gates of up to 18 meters can be supplied
(code ACG7089).
MAINTENANCE

Clean the sliding guide of stones and dirt periodically only when the gate does not move.
ALWAYS USE AN OPEN/CLOSE PUSH BUTTON WHICH IS DESIGNED TO
PREVENT THE POSSIBILITY OF SIMULTANEOUSLY SENDING THE OPPOSITE
