SECURING SCREWS
5.4.1 OPERATOR WITHOUT MECHANICAL EMERGENCY RELEASE
1) Take the gate to its open position.
2) Consulting the instructions in chapter 8.1, hydraulically release
the operator, using the key (Fig. 1 ref.
r
) on the release screw
(Fig. 1 ref.
f
)
3) On the operator, unscrew the plug (Fig.16 ref. A) of the screw
of the closing travel limit device (Fig. 16 ref.
a
).
4)
Back off the closing travel limit screw (Fig.6 ref. B) by
one turn (IMPORTANT FOR CORRECT COUPLING OF THE
PINION-GROOVED BUSH DURING INSTALLATION).
5) Turn the operator pinion with the supplied wrench (Fig. 1
ref.
r
),
in the
gate closing direction
as shown in Fig. 16, up to
the internal stop point of the piston, and remove the key.
8) Using the handles, insert the operator in the bearing case as
shown in Fig. 18 A,
9) Close the gate.
10) Raise the operator with its handles (Fig. 18 ref. B), inserting
the pinion in the grooved bush of the bearing case. To facilitate
the operation, slightly rotate the operator until coupling takes
place.
11) Insert and screw the fastening screws with groover and washer
as shown in Fig. 18 B ref.
a
, in order to secure the operator to
the bearing case. (TO FACILITATE THE OPERATION, SUPPORT THE
MOTOR FROM THE CENTRAL PART)
12) Open the gate and check if the opening travel-limit stop
is correctly positioned; if necessary, adjust the travel-limit stop,
referring to the instructions in chapter 6.
13) Close the gate and check if the closing travel-limit stop is
correctly positioned; if necessary, adjust the travel-limit stop,
referring to the instructions in chapter 6.
14) Hydraulically shut down the operator as per instructions in
chapter 8.1.
15) As described in the instructions for the control board, make
the electrical connections, taking care over encoder polarity.
16) Secure the cover of the bearing case with the supplied
screws.
6)
Without moving the pinion,
insert the supplied wrench on the
operator as shown in Fig. 17, and make sure that it indicates 0
(ZERO) on the operator’s plastic panel (Fig. 17 ref.
a
). If necessary
rotate the pinion with this.
(IMPORTANT FOR CORRECT COUPLING
OF THE PINION-GROOVED BUSH DURING INSTALLATION).
NOTE: if necessary, lightly screw the closing travel-limit screw
7)
Remove the adjustment wrench, screw the plug of the travel
limit screw and grease the pinion.
IMPORTANT: REMOVE THE ENCODER BEFORE YOU
BEGIN MECHANICAL INSTALLATION
