06 . Slightly loosen the travel limit mechanical stop screw and manually open
the door until it reaches the maximum
Opening
position ( fig. 28 ) .
07 . Move the travel limit mechanical stop up against the carriage .
Then tighten the travel limit mechanical stop screw fully down ( fig. 29 ) .
Note – During normal operation the carriage stops a few centimetres
before the mechanical stop.

. To re-block the door, close it manually until it clicks firmly into place.
STEP 6
After installing all devices in the system – each in the position specified in STEP
4 – connect each device to the control unit as follows .
CAUTION! – Incorrect connections can cause faults or hazards; there-
fore ensure that the specified connections are strictly observed.
01.
Use a screwdriver to loosen the screw on the control unit cover and
extract the cover ( fig. 30 ), to access the terminals for electrical connec-
tions of the control unit .
02. Use the same screwdriver to open the slots required for routing the elec-
tric cables (
fig.
31) from the various devices in the system .
03. Then connect the electric wires of the system devices to the control unit
using the terminal board with five terminals (
fig. 32
) .
CAUTION – The section of electric cable connecting terminals 3
and 5 must only be removed if photocell installation is envisaged.
For correct connections, proceed as follows:
• To connect a pair of photocells with safety function
One or more pairs of photocells with a safety function must be installed on the
system . If several pairs of photocells are installed, these must be connected in
series , and the chain must be connected to terminals 3 and 5 on the control
unit . The connect the power supply to terminals 2 and 3 (see example in fig.
33 and fig. 34 ) .
During the Closing manoeuvre, activation of these photocells causes shutdown
of the manoeuvre and immediate inversion of movement .
• To connect a NO type pushbutton used for manoeuvre control
An “ NO ” type pushbutton can be installed on the system, i .e . “ normally open ”
to control manoeuvres in “ step-step ” mode (for details on this mode, see
STEP 9 ) . Connect this pushbutton to terminals 3 and 4 on the control unit .
Note
– If several pushbuttons are installed to control manoeuvres, connect
these in parallel as shown in the example in fig. 35 and fig. 36 .
• To connect safety devices other than photocells
As well as photocells, the system can also be equipped with other safety devic-
es with different types of contact . These are:
– devices with “
normally open ” contact (“ NO ”);
– devices with “ normally closed ” contact (“ NC ”);
– devices with constant resistance 8,2 KΩ .
These devices can be connected to terminals 1 and 2 on the control unit; also
mo re than one device can be connected to the same terminals as described
below:
A
) – to connect a series of “
NO
” type devices, use a “parallel” connection lay-
out as shown the example in fig. 37 .
B ) – to connect a series of “ NC ” devices, use a connection layout “in series” as
shown in the example in fig. 38 .
C ) – to connect a series of devices with constant resistance 8,2 KΩ , use
a “parallel” connection layout, positioning the resistance (8,2KΩ) on the last
device, as shown in the example in fig. 39 .
D
) – to connect a series of devices with different contact types (“
NO
”, “
NC
” and
constant resistance 8,2 KΩ ), use a connection layout in series and in parallel
as shown in the example in
fig. 40
.
Note – Only the safety devices with an output with constant resistance
8,2 KΩ guarantee safety category 3 against faults according to the
standard EN 954-1.
Activation of these safety devices stops the manoeuvre in progress and a brief
inversion of movement .
• Powering devices other than those specified in this chapter
As well as those mentioned, the system can also be equipped with other safety
devices such as a universal relay receiver . These devices must be connected
to terminals
2
and
3
on the control unit .
Caution! – There is a 24 Vdc power
voltage on terminals 2 and 3 with delivery of a current of 100 mA. The
total absorbed current of the various devices connected to these termi-
nals must not exceed this value.
WARNING – On completion of connections, secure all cables using special
clamps and refit the cover on the control unit.
STEP 7
WARNINGS!
– The PVC power cable supplied is suitable for indoor installations.
The final connection of the automation to the electrical mains, must be
performed by a qualified electrician, in compliance with local standards
and the instructions in the section “
Tasks reserved for qualified techni-
cians”.
To perform the automation operation and programming tests, insert the power
plug of the control unit
(supplied) in a mains socket (
fig. 41
) . If the socket is
far from the automation, use a suitable extension lead .
POWER SUPPLY CONNECTION
STEP 8
CAUTION! The following operations described in this manual will be
performed on live electrical circuits and therefore manoeuvres may be
hazardous! Therefore proceed with care.
After powering up the control unit ( fig. 41 ) perform the following operations,
checking conformity of results:
• Immediately after start-up, the red led ( fig. 42 ) flashes quickly for a few sec-
onds, after which the red and green leds light up alternately; then the green
led turns off and the red led continues flashing at regular intervals every second
(= control unit operating status OK ) .
CAUTION! - If the red led does not flash as described above, discon-
nect the Control unit from the power supply and carefully check all
connections (refer also to the paragraph “ What to do if.... ”).
• If the system is equipped with photocells, check the RX element to ensure
that the led is OFF (= operation OK ) or ON (= obstacle present ) . If the Led is
flashing, this means that the signal is poor and subject to incorrect photocell
alignment .
• If the system is equipped with a radio control keypad, check operation with
reference to the relative instruction manual .
