5 INTERNAL MECHANICAL TRAVEL-LIMIT STOPS
(POSITIVE STOP
)
The S800H 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.

TRAVEL-LIMIT STOP
AT OPENING
TRAVEL-LIMIT STOP AT CLOSING
1) Hydraulically release the operator. (See chpt 7.1)
2) Close the leaf, manually taking it into its closed position.
3) Unscrew the cap (Fig.23 ref.A) of the closing travel-limit screw
(Fig.23 ref.
a
)
4) UNSCREW the travel-limit stop screw (Fig.25 ref.B) at closing
(Fig.25 ref.
a
), until the leaf begins to move.
5) Fasten the cap (Fig.23 ref.A) of the travel-limit stop screw.
6) Open the leaf, manually taking it into its opening position.
7) Unscrew the cap of the screw (Fig.23 ref.A) of the opening
travel-limit stop (Fig.23 ref.
b
).
8) UNSCREW the travel-limit stop screw (Fig.23 ref.
b
), until the
leaf begins to move.
9) Fasten 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.

17) Open and close the gate, checking and, if necessary,
adjusting the respective travel limit devices as described in
chapter 5.
18) As described in the instructions for the control unit, make the
electrical connections, taking care over encoder polarity.
19) Hydraulically shut down the operator as per instructions in
chapter 7.1.
BEFORE CARRYING OUT THE RELEASE AND SHUT-DOWN
OPERATIONS, MAKE SURE THAT YOU HAVE CUT POWER
TO THE OPERATOR AND THAT IT IS NOT MOVING
7 MANUAL OPERATION
6 FINAL OPERATIONS
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.
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
(Fig.24;25).
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.
