5.3. ADJUSTMENT OF STROKE END DECELERATION
1)
Position microswitch SW6 according to the amount of
deceleration required:
OFF: SHORT (1.5 sec).
ON: LONG (2.5 sec).
For beams up to 4 m long, a short deceleration is
recommended. For beams from 4 to 7 m, a long
deceleration is recommended.
2)
Adjust the stroke limit cams by loosening the two Allen
screws, as shown in Figure 17. To increase the
deceleration angle, move the cam toward the limit
switch. To decrease the deceleration angle, move
the cam away from the limit switch.
3)
Re-lock the system (see paragraph 6), and carry out a
few test cycles, in order to check whether the
positioning of the limit switches, the balancing of the
spring, and the transmitted torque are correct.
5.4 TESTING THE AUTOMATION SYSTEM
Once installation is complete, affix the danger warning
adhesive on the top of the housing (Fig. 18).
Carry out a thorough functional check of the barrier unit
and all accessories connected to it. Give the page entitled
“End-user guide” to the customer and demonstrate how
to operate the barrier correctly, drawing the customer’s
attention to the points of potential danger.
6. MANUAL OPERATION
If the barrier needs to be operated manually as a result of
a power failure or malfunction, use the unlock device as
follows.
The key provided can be triangular (standard) or
personalised (optional).

OPERATION OF WARNING LIGHT
(*) Warning light connected between terminals 8 and 10.
(**) Warning light connected between terminals 9 and 10.
5.2. ADJUSTMENT OF TRANSMITTED TORQUE
Use the two by-pass screws (fig. 8) to regulate the hydraulic
transmitted torque adjustment system.
The red screw adjusts torque during closure.
The green screw adjusts torque during opening.
Turn the screws clockwise to increase torque.
Turn the screws anticlockwise to reduce torque.
