OTOR 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.

IMIT 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).
M
AINTENANCE
To be undertaken only by specialized staff after disconnecting
power supply.
Clean the sliding guide of stones and dirt periodically only when the
gate does not move.
