2. ELECTRICAL SETUP (fig. 2a Standard system)
a
961 B-E operator
b
Microwave radar / Passive infrared sensor
c
T20E external key-switch (KEY command)
d
Emergency Closing/Opening pushbutton
e
CODIS programming unit (optional)
f
CODIS inhibition switch (optional)
g
24 Vdc electric lock
h
Junction box
If the operator is installed on the door, make the electrical
connections using a junction box and suitable commercially
available pipes/unions
(fig. 2b)
.
N.B.:
1) For installation of electrical cables use suitable rigid
or flexible piping.
2) Always keep the low voltage accessory connection
cables separate from the 230 V power cables. Use
separate sheaths to avoid any interference.
3. INSTALLATION
3.1 PRELIMINARY CHECKS
To ensure correct operation of the automatic unit the structure
of the existing door must meet the following requirements:
- length and weight as specified in Table 3 (section 1.1);
- max. doorpost depth as specified in Table 4;
- robust and rigid structure of the leaf;
- good condition of the existing hinges;
- smooth, uniform movement of the leaf with no abnormal
friction at any point of its travel;
- “neutral” position of the door during its entire travel. If the door
tends to close or open, check the alignment of the hinges.
- Presence of mechanical end stops.
3.2 MOUNTING THE OPERATOR
1)
Remove the protective casing (fig. 3) and the end covers
(fig. 4) from the operator.
Warning
: Before removing the end cover with the function
switch, remove the connector joining the switch to the 960MP
electronic control unit.
2)
As regards the mounting position of the operator (on the
lintel or on the door) and the type of arm to use (pushing,
pulling or sliding), refer to the relevant mounting table and
drill the holes required to mount the operator and the
pulling arm.
N.B.:
The two intermediate operator fixing holes are not in a
central position (see mounting tables). The holes are offset in
order to ensure that the operator is mounted with the correct
direction of rotation of the mechanism.
The mounting tables are the following:
Table A: LINTEL MOUNTING (PUSHING ARTICULATED ARM)
Outward opening
Table B: DOOR MOUNTING (PUSHING ARTICULATED ARM)
Inward opening
Table C: LINTEL MOUNTING (PULLING ARTICULATED ARM)
Inward opening
Table D: LINTEL MOUNTING (SLIDING ARM)
Inward opening
3)
Mount the operator using the six M6 screws and washers
provided.
Warning
:
- The structure of the lintel (or the door) at the operator
mounting position must not exhibit any significant
deformation.
- The operator must be mounted parallel to the floor.
N.B.:
If the sliding arm is to be used, the driving arm must be
mounted before the operator is fixed on the lintel (see section
3.3.3.).
3.3
MOUNTING THE DRIVING ARMS
3.3.1
MOUNTING THE PUSHING ARTICULATED ARM (fig. 5)
1)
Close the door.
2)
Free arms (1) and (2) by pulling apart the coupling (3)
manually as shown in fig. 5.
3)
Fit arm (1) on the operator transmission shaft by means of
the extension and the screw (4) provided (fig. 5). The arm
must be mounted perpendicular to the closed door.
N.B.:
If a greater distance between the operator and the arm
is required, use the higher extensions available as accessories
(see Table A/B).
4)
Mount plate (5) of arm (2) on the door or the lintel using the
two M6 screws and the washers provided (fig. 5). The
installation distances are given in Table A/B.
5)
Slacken the fixing screw (6) and assemble the two arms by
means of coupling (3) (fig. 5).
6)
Turn arm (1) until arm (2) is perpendicular to the closed
door or the lintel as shown in fig. 5 (a-b), sliding the spacer
(7) along arm (2).
7)
Tighten the fixing screw (6) between the two arms.
The length of arm (2) is given in the relevant mounting
tables. If necessary, cut off the section of the arm extending
beyond the articulation and then cover the ends using the
caps provided (fig. 5).
8)
Check manually that the door is free to open and close
fully and that it comes to rest against the mechanical end
stops. If the door does not close correctly, adjust the return
spring as described in section 10.
Important
: The two driving arms must never touch.
N.B.
: For 90
°
opening it is not necessary to install the mechanical
opening stop (microswitch no. 2 in OFF position - see section 5).
3.3.2
MOUNTING THE PULLING ARTICULATED ARM (fig. 6)
1)
Close the door.
2)
Free arms (1) and (2) by pulling apart the coupling (3)
manually as shown in fig. 6.
3)
Fit arm (1) on the operator transmission shaft by means of
the extension and the screw (5) provided (fig. 6). The arm
must be mounted parallel to the closed door.
N.B.:
If a greater distance between the operator and the arm
is required, use the higher extensions available as accessories
(see Table C).
4)
Mount plate (6) of arm (4) on the door using the two M6
screws and the washers provided (fig. 6). The installation
distances are given in Table C.
5)
Slacken the screws (7) and slide the attachment (8) along
arm (4) so as to position it at distance D given in Table C.
Having done this, tighten screws (7).
6)
Slacken screw (9) and assemble the two arms using the
coupling (3) (fig. 6).
7)
Turn arm (1) as shown in fig. 6(a) until it reaches a distance
of 83 mm from the lintel. Having done this, tighten the fixing
screw (9) between the two arms. If necessary, cut off the
section of the arm extending beyond the articulation and
then cover the ends using the caps provided (fig. 6).
8)
Check manually that the door is free to open and close
fully and that it comes to rest against the mechanical end
stops. If the door does not close correctly, adjust the return
spring as described in section 10.
Important:
The driving arms must never touch.
3.3.3
MOUNTING THE SLIDING ARM (fig. 7)
1)
Mount arm (1) on the operator transmission shaft by means
of the extension and the screw (2) provided (fig. 7). The
arm must be fitted pointing 45
°
outwards as shown in fig.
7(a).
N.B.:
If a larger distance is required between the operator and
the arm use the higher extensions available as accessories
(see Table D).
Warning
: Mount arm (1) on the transmission shaft before fitting
