6.2 FINAL ADJUSTMENT OF THE LIMIT SWITCHES
To correctly adjust the limit switches, the control unit must be installed and correctly connected with all the
control and safety accessories.
The stopping and deceleration of the gate, during opening and/or closing, occurs when the cams inside the device activate the mi-
croswitches corresponding to the assigned function.
FCO = opening limit switch (screw 3)
FCC = closing limit switch (screw 2)
ROP = start of opening deceleration (screw 4)
RCL = start of closing deceleration (screw 1)
1. Prepare the operator for MANUAL operation, as described in section 8.
2. Loosen the screws and remove the limit switch unit cover (Fig. 20 ref.  ).
3. Set the sliding leaf in open position, at least 10 cm before the mechanical limit stop.
4. Loosen the central locking screw of the limit switch unit (Fig. 22 ref. ).
5. Turn the screw corresponding to the FCO opening limit switch (Fig. 21 ref. ) until the microswitch is engaged by the cam.
6. In chart 1, knowing the weight of the sliding leaf, choose the operating speed and calculate the corresponding MINIMUM STOP
SPACE S[mm].
7. Then, move the sliding leaf back in closing position according to the amount of identified STOP SPACE.
8. Turn the screw corresponding to ROP opening deceleration (Fig. 21 ref. ) until the microswitch is engaged by the cam.
9. Place the sliding leaf in closed position, at least 10 cm before the mechanical limit stop.
10. Turn the screw corresponding to the FCC closing limit switch (Fig. 21 ref. ) until the microswitch is engaged by the cam.
11. Move the sliding leaf back in opening position according to the amount of STOP SPACE identified in chart 1.
12. Turn the screw corresponding to RCL closing deceleration (Fig. 21 ref. ) until the microswitch is engaged by the cam.
13. In chart 2, knowing the weight and the operating speed of the sliding leaf, calculate the corresponding DECELERATION TIME t[s].
