EMERGENCY RELEASE

To be undertaken after disconnecting power supply.
To open the gate manually, in case of power failure, you should turn RIB key clockwise.
To restore electric working you have to turn the lever anti-clockwise (Fig. 4).
In order to carry out the manual operation of the gate leaf the followings must be
checked:
- That the gate is endowed with appropriate handles;
- That these appropriate handles are placed so to avoid safety risks for the operator;
- That the physical effort necessary to move the gate leaf should not be higher than 225
N, for doors/gates for private dwellings, and, 390N for doors/gates for commercial and
industrial sites ( values indicated in 5.3.5 of the EN 12453 norm) .
MOTOR AND RACK INSTALLATION
The base of the K5 is equipped with 2 anchors so that it can be cemented to the ground.
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 rack must not be welded, but simply fixed to the gate with threaded screws.
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 5 mm should be made to fix the rack into the gate, and they
should be threaded using a M6 type screw tap.
The pinion must have a clearance of 0,5 to 1 mm with respect to the rack.
LIMIT SWITCH ADJUSTMENT
The gate stops thanks to the two cams, which are placed at each end of the rack (Fig. 7).
The regulation of the opening and closing stroke can be obtained by displacing these on
the rack.
To fix the cam, screw the screws (fig.7 - point 1).
N.B.: In addition to the above-mentioned limit switch it is compulsory to install solid
mechanical stops, which prevent the gate from sliding off the upper guide bearings.
MAINTENANCE
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.
