MOTOR AND RACK FITTING
Operator K500 comes with a base plate for vertical adjustment.
Such adjustment proves to be useful to set a 1mm clearance between the drive gear and
the rack.
The base plate is provided with three brackets that can be used to fasten the equipment
to the floor. As an alternative, it is possible to obtain the special to type plate for type K500
(code ACG8108) to be secured directly to the floor.
In addition, it is possible to install the equipment K500 complete with base plate, directly
over the installation plate, as suitable for operator K5 (code ACG8101).
The base plate for operator K500 features four holes for floor securing, through four
expansion studs.
The rack shall be fitted over the motor support, at a certain distance from it.
Its height can be adjusted thanks to the holes In the rack.
The height is adjusted to prevent the gate from resting on the driving gear of the K as it
moves (Fig. 5, 6).
To fix the rack on the gate, drill some Ø 5 mm holes and thread them using an M6 screw tap.
The driving gear needs some 1 mm clearance from the rack.

LIMIT SWITCH FITTING
In order to determine the travel of the moving part, place two cams at the ends of the
rack (Fig. 9).
Move the cams on the rack teeth to adjust their opening and closing travel.
To fix the cams to the rack, tighten the screws issued.
N.B: In addition to the electric stop cams mentioned above, you must also install strong
mechanical stops preventing the gate from sliding out of the top guides.
MAINTENANCE
To be carried out exclusively by skilled persons after the power supply to the motor has
been interrupted.
Periodically, when the gate is standstill, clean and keep the guide free from stones and dirt.
