TESTING THE AUTOMATION SYSTEM

Once installation is complete, affix the danger warning
decal on the top of the housing (Fig. 20).
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 may be triangular (A, fig. 21  - standard),
or personalised (B, fig. 21 - optional).
Insert it in the lock and turn it 1 revolution anticlockwise(Fig.
21).
- Open or close the barrier manually.

7. RETURNING TO NORMAL OPERATION

To prevent an accidental impulse from activating the
barrier, turn off the system’s electrical power supply before
engaging the lock system.

A)   triangular key (standard):

- turn the key clockwise until it stops, then remove it (A, Fig.

21).

B)   customized key (optional):

- turn the key clockwise until it stops.
- turn the key anticlockwise very slowly to the point where

it can be removed (B, Fig. 21).

5.5.

ADJUSTMENT OF TRANSMITTED TORQUE

Use the two by-pass screws
(fig. 18) 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.

5.6.

ADJUSTING DECELERATION

1)

The deceleration of barrier 620 SR is factory-set.
However, if small adjustments are required, turn the
adjusting screws 1 and 2 in fig. 19.
Turn clockwise to increase deceleration, anticlockwise
to reduce deceleration.
IMPORTANT: A 1/2 turn of the screw is sufficient for the
adjustment.

2)

The ideal setting of the limit switch cams (3 and 4, fig.
19) is when the microswitch is tripped at the same time
the mechanical travel limit is reached.
