ENGLISH
OPEN-A
Terminals "16-19". Any device (e.g. push-button, remote control,
etc.) can be connected to this circuit.
By closing a contact, the circuit generates a pulse for total
opening and/or closing of the gate. Its operating mode is set
by dip-switch 3 – see the relevant paragraph.
N.B. : an OPEN-A pulse during the pedestrian stage always has
priority over that stage
N.B. : to install several pulse generators, connect the contacts in
parallel.
Photocells
Terminals "17-19". Any safety device (e.g. photocell, sensitive
strip, etc.) can be connected to this circuit. By opening a
contact, the circuit protects closing motion. The status of this
input is signalled by the FTO LED. It also has an effect on opening
motion, depending on how dip-switch 4 was set – see relevant
paragraph.
N.B. : If safety devices are not connected, fit a jumper at input.
To install several safety devices, connect the NC contacts in
series.
STOP
Terminals "18-19". Any device (e.g. push-button, remote control,
etc.) can be connected to this circuit.
By opening a contact, the circuit stops gate movement. The
status of this input is signalled by the STOP LED. The set cycle will
restart only if a successive opening or closing pulse is received.
N.B. : If STOP devices are not connected, fit a jumper at input.
To install several STOP devices, connect the NC contacts in series.
6. FITTING DECODING/RP RECEIVER CARDS
Installation procedure: turn off power and fit the module in
container M5 inside the control unit. Then observe the radio-
receiver instructions to store data on the remote-control. After
the necessary data has been stored, the remote-control
activates OPEN-A like any other command device.

photocells covered
command active
9. PROGRAMMING
Programming of work times, deceleration and electronic clutch
is executed during self-learning. At this stage, leaf movement is
at slow speed.
Important: the self-learning procedure must be executed with
back-up batteries (optional) disconnected.
Procedure:
1) Release the leaves, take them to about midway through
opening travel, and then lock them.
2) Power up the control unit (power ON is signalled by the POWER
LED).
3) Turn switch S2 to PROG: the flashlight goes on at steady light
to signal programming.
4) Press the push-button connected to the OPEN-A terminals or
the remote-control, if already programmed. The first operation
the automation performs must be CLOSING. First, the leaf
connected to M2 closes, and then the one connected to
M1.
5) If the leaves move to open, touch the two RESET pins with a
screwdriver – the control unit will immediately stop the
movement generated by the automation.
6) Cut power to the control unit, reverse polarity of the two
cables powering the motors which had supplied opening
drive, and repeat the operation at point 1.
7) After the OPEN-A command is given, the leaves move to close,
until they reach the closing gate stop.
8) After about two seconds, the leaf connected to M1 restarts
opening automatically, and after another two seconds, the
leaf connected to M2 also restarts until it reaches the opening
gate stops.
9) The control unit begins counting pause time. After the required
time has elapsed, press the OPEN-A command again, and
the leaf connected to M2 restarts closing. After the set time
difference has elapsed, the leaf connected to M1 restarts too
until it reaches the closing gate stops.
10)Programming is now finished. Turn switch S2 back to OFF –
the flashlight goes off.
10. OPERATION OF ELECTRONIC CLUTCH
This is a very important device for safety. Its setting does not alter
through time, as the device is not subject to wear or setting
changes.
It is active both at closing and opening. When it operates it
reverses motion direction without inhibiting automatic closing if
enabled.
If it operates twice in succession, it moves to STOP position,
disabling any automatic command.
This is why: if the clutch operates twice, this means the obstacle
is still present and any further manoeuvres could be dangerous,
thus obliging the user to give an opening or closing command.
In that case the control unit executes an EMERGENCY proce-
dure as follows: full opening at slow speed up to the opening
gate stop, followed by automatic closing to enable the gate
stops to re-synchronise independently.
