8 MANUAL OPERATION
8.1 HYDRAULIC RELEASE OF THE OPERATOR
If the gate has to be moved manually due to a power cut or
fault of the automated system, use the hydraulic release device
with the release key (Fig.21 ref.
b
):
1) Remove the cover from the bearing case.
2) Turn the release screw (Fig.21 ref.
a
) inserting the triangular
recess of the supplied key (Fig.21 ref.
b
):
- To RELEASE, turn the screw anti-clockwise by at least one
turn. (DO NOT COMPLETELY UNFASTEN THE SCREW TO AVOID OIL
COMING OUT.
- To
SHUT-DOWN
again, turn the screw clockwise up to the
mechanical stop point.

8.2 MECHANICAL EMERGENCY RELEASE
(OPTIONAL)
For the S700H operator, a manual mechanical emergency
release is available as an optional item.
If the gate has to be moved manually due to a power cut or fault
of the automated system, use the release key device.
The device is inserted on the gate support bracket (fig. 22 ref.
a
) and enables you to release the system from both inside and
outside the premises.

7 FINAL OPERATIONS
1) Place the encoder in its seat on the motor.
2) Connect the motor (Fig.1 ref.
h
) and the encoder (Fig.1
ref.
i
) to the control unit, following the specific instructions.
3) Secure the cover of the bearing case with the supplied
screws.
4) Where specified by current legal regulations, place at least
two signs with the words “Danger: Automatic motion” on both
sides of the automated system.
To avoid excessive voltage drops, we recommend
that the length of the motor cables with a
section of 2.5 mm, should not exceed 20 m.
The maximum total length of the BUS cables must not
exceed 100 m.
4) Unscrew the travel-limit stop screw (Fig. 20 ref.B) at closing
(Fig.20 ref.
a
), until the leaf begins to move.
5) Fasten the lock-nut of the travel-limit stop screw.
6) Open the leaf, manually taking it into its opening position.
7) CREW the cap of the screw of the opening travel-limit stop
(Fig.20 ref.
b
).
8) UNSCREW the travel-limit stop screw (Fig.20 ref.
b
), until the
leaf begins to move.
9) CREW the cap of the travel-limit stop screw.
10) Open and close the gate to check if the travel-limit stop is
correctly adjusted.
11) Shut-down the operator again, following the instructions in
chapter 7.1.
