AUTOMATED SYSTEM S700H
1 DESCRIPTION
These instructions apply to the following models:
S700H SB - S700H CBAC / 100° - 180°.
FAAC S700H is an automated system in a hydraulic enbloc (CLASS III), permitting vehicle access through swing leaf gates which,
when installed invisibly in the ground, does not alter the appearance of the gate.
The model with a hydraulic shut-down facility does not require installation of an electrical lock, as it guarantees mechanical
shut-down of the leaf up to 2 m when the motor is not operating. The model without a hydraulic shut-down facility always requires
one or more electrical locks to ensure the leaf is mechanically shut down.
The S700H automated systems were designed and built to automate swing leaf gates. Do not use for any other purpose.

5 INSTALLING THE AUTOMATED SYSTEM
5.1 PRELIMINARY CHECKS
To ensure a correctly operating automated system, the structure
of the existing gate or gate to be built must satisfy the following
requirements:
1) Individual leaves must not weight more than 800 kg.
2) Maximum length of single gate: 2 mt CBAC, 4 mt SB
3) A strong and rigid leaf structure.
4) Smooth, uniform gate movement, without any irregular friction
during the entire travel.
5) Distance “A” between lower edge of gate and ground as
shown in Fig. 7.
6) The distance between the gate leaves - in the opening and
closing positions - and the existing structures, must respect
current legal regulations
We advise you to carry out the metalwork jobs before installing
the automated system.
The condition of the structure directly influences the reliability and
safety of the automated system.

6 POSITIVE STOP - (INTERNAL MECHANICAL TRAVEL-LIMIT STOPS)
The S700H operator is supplied standard with internal opening
and closing mechanical stops. This is to facilitate the installation
operations because there is no need to construct the mechanical
stop elements.
The mechanical travel-limit stops (POSITIVE STOP) can be adjusted
in the last 30° of the operator’s MAXIMUM travel, at both opening
and closing.

OPERATIONS, MAKE SURE THAT YOU HAVE CUT POWER
TO THE OPERATOR AND THAT IT IS NOT MOVING
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.
Fig.21
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
th at 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.

9.1 OIL LEVEL CHECK
Check oil level periodically by unscrewing the filling plug (Fig.1

top up.
Topping-up operations must be done only with FAAC HP OIL.
OPENING BLEED
SCREW
CLOSING BLEED
SCREW
Fig.24
The presence of air in the hydraulic circuit causes the automated
system to operate incorrectly, i.e. a faulty movement of the leaf
and too much noise while operating.
Procedure to avoid this problem:
1) Command the gate to open.
2) While the leaf is moving, loosen the opening bleed screw
(Fig.24 ref.a)
3) Using the bleed screw, allow the air to come out from the
hydraulic circuit until non-emulsified oil appears.
4) Tighten the bleed screw before the operator finishes the
opening cycle.
5) Command the gate to close.
6) While the leaf is moving, loosen the closing bleed screw
(Fig.24 ref.b)
7) Using the bleed screw, allow the air to come out from the
hydraulic circuit until non-emulsified oil appears.
8) Tighten the bleed screw before the operator finishes the
closing cycle.
9) Repeat these operations several times.
10) Top up oil level, referring to the instructions in this chapter.
9.2 BLEEDING OPERATIONS
THE S700H OPERATOR IS SUPPLIED WITH THE HYDRAULIC
CIRCUIT ALREADY AIR FREE. DO NOT BLEED. BLEEDING
IS ONLY NECESSARY IN THE EVENT OF MAINTENANCE OF
THE HYDRAULIC SYSTEM OR TOPPING-UP OIL LEVEL.
9 MAINTENANCE
Run a functional check of the system at least every 6 months,
with special attention to the efficiency of the safety and release
devices (including the thrust force of the operator), and to perfect
operation of the gate hinges.
Also, periodically check quantity of oil inside the tank.
The safety devices installed on the system must be checked
every 6 months.
