5 START-UP
5.1 ADJUSTING THE BALANCING SPRING.
The barrier is supplied already balanced for the exact length of
the beam indicated in the order.
(The barrier is balanced when, with the beam released, the beam
stays idle in the 45° position)
For any fine tuning of barrier balancing, proceed as follows:
)
Make sure that the operator is released: see chapter 6.
)
If the barrier tends to close, turn the spring pre-loading
ring-nut (Fig. ref.) clockwise; if it tends to open, turn it
anti-clockwise.

5.2 CONNECTION TO CONTROL BOARD
IMPORTANT: Before attempting any work on the control unit
(connections, maintenance, etc), always turn off power.
For the electrical connections, refer to the dedicated instructions
of the control unit.
Observing the indications in fig., install the raceways and
make the electrical connections from the control unit to the
selected accessories.
Always separate power cables from control and safety cables
(push-button, receiver, photocells, etc.).
5.3 ADJUSTING THE TRANSMITTED TORQUE
To set the hydraulic system for controlling transmitted torque, turn
the two by-pass screws (Fig. ).
The red screw controls closing movement torque.
The green screw controls opening movement torque.
To increase torque, turn the screws clockwise.
To reduce torque, turn the screws anti-clockwise.
The deceleration of barrier 60 SR is factory-set.
However, if small adjustments are required, turn the
adjusting screws B and B in fig. .
Turn clockwise to increase deceleration, anticlockwise
to reduce deceleration.
IMPORTANT: A / turn of the screw is sufficient for the
adjustment.
5.4 ADJUSTING THE TRAVEL LIMIT SLOW DOWN
)
Adjust the cams of the travel limit device as shown in Fig.
4 ref. a by loosening the two Allen screws. To increase the
slow down angle, take the cam close to the relevant travel
limit device. To reduce the slow down angle, take the cam
away from the relevant travel limit device.
)
Set the slow down time of the control unit by adjusting the
dedicated parameters.
)
Relock the system (see chap.7) and run a few operational
tests to verify correct registration of the spring balancing travel
limit devices and of the adjustment of transmitted force.
