If there is more than one device on this contact (PHO1), they must
be connected in series.
It is possible to connect normally closed contact devices to the “
PHO1
” input (terminal 16,18). These devices operate during the
closing cycle.
In particular:
- in closing phase, an immediate inversion of the motion.
- in opening phase, they have no effect.
- if the access is closed, they have no effect.
- if the access is open, they inhibit the closing commands.
If there is more than one photocell, the receivers and the transmitters
must be alternated (see picture 1).

If there is more than one device on this contact (PHO2), they must be connected in series.
If there is more than one photocell, the receivers must be alternated (see picture 1)

The activation of the self-test, without having properly connected the photocells to the control unit, will cause a
malfunctioning of the system.
Press button P2/RAD for 2 seconds to know the state of self-test (activated or deactivated): if the red led “RAD” turns on, it
means that the self-test is disabled; if the red led “RAD” and the yellow led “SET” turn on, it means that the self-test is active.

11B - OPENING SAFETY DEVICES
Depending on the regulation of trimmer “
OBS
” (see paragraphs 4B, 8), the control unit could be more sensitive (and invert the
motion more easily) in case of impact of a wing against an obstacle. However, a too sensitive regulation of the trimmer, together
with a worsening of the condition of the system caused by the passage of time, could cause unexpected interventions in the
points where the motors absorb more current.
11D - OBSTACLE DETECTION BY POWER ABSORPTION
The control unit has a self-test function of the safeties connected to the “
PHO1
” and “
PHO2
” input. It switches off the transmitter
to check the commutation of the corresponding receiver contact before the execution of each manoeuvre. To activate this
self-test function proceed as follows:
- connect the positive of the photocell transmitter power to the terminal “
+TX
” (terminal 20) instead of the terminal “
+VA
”
(terminal 19).
- make the programming procedure, as follows.

DEACTIVATION
In the “
START
” input (terminals 12, 13) it is possible to connect a normally open contact (for example, key selectors, or
switches) to manage the automation. The commands can be set by dip switches 2, 3 and 7 (see paragraph 4A, 5). There are 2
micro switches in the selectors; each one has its own function.
Picture 1 shows the terminals in which is possible to connect a micro switch for the starting command.
A selector can also issue a starting command with both the contacts connected in parallel (see picture 2).
10 - CABLE COMMANDS CONNECTABLE
!
If there is more than one stop contact, they must be connected in series (see picture 2).
!
If there is more than one pedestrian opening contact, they must be connected in parallel (see picture 2).
!
If there is more than one opening contact, they must be connected in parallel (see picture 2).
Keeping the opening contact closed (“STR” terminal, for example with a relay), the control unit perform the
opening, and the automation doesn’t accept closing commands (neither automatic, nor by wire), as long as the
contact will be opened again.
!
The pedestrian opening is a partial opening (or total opening, if the installer wants it) of the wing opened by “
MOT1
” (terminals
24, 25). To activate the pedestrian opening function, it is necessary to make the pedestrian opening programming procedure
(see paragraph 7). The pedestrian opening can be managed by a channel of the transmitter (see paragraph 3B) and/or by wire,
connecting a normally open contact to “
PED
” input (terminals 13,15).
Picture 1 shows the terminals in which it is possible to connect a micro switch for the pedestrian opening command.

In the “

every function. Picture 1 shows the terminals in which it is possible to connect a stop button. To restart the functions, it is
necessary to deactivate the stop command.

It is possible to connect normally close contact devices to the “
PHO2
” input (terminal 17,18). These devices operate during opening
and closing cycles depending on the setting of
DIP4
“PHO2”
(see paragraph 4A)
DIP4 SET TO ON (Internal photocell):
- in
closing phase
they continue the movement as soon the
device has been cleared
- in
opening phase
they continue the movement as soon the
device has been cleared
- if the
access is closed
they inhibit the opening commands.
- if the
access is open
they inhibit the closing commands.
DIP4 IN OFF (safety edge in opening):
- in
closing phase
they have no effect
- in
opening phase
an immediate inversion of the motion
for 2 seconds
- if the
access is closed
they inhibit the opening commands.
- if the
access is open
they have no effect
