The unit comprises a set of microswitches used to operate various
functions so as to render the system more suitable to user needs
and safer in the different ways of usage. All functions are activated
by placing the dip-switch in the “ON” position while they will not be
activated if the corresponding dip-switches are “OFF”; some func-
tions do not have an immediate effect and only have sense in certain
conditions like.

ATTENTION: some of the programmable functions are

linked to safety aspects, very carefully evaluate the effects of
a function and see which function gives the greatest possible
level of safety.

When servicing a system, before you modify a programmable func-
tion, ascertain the reason why, during installation, certain choices
were made and then verify if, with the new programming, safety will
be impaired.

5) Programming

4.1) Operating modes

In the manual operating mode, the OPEN input enables an opening
movement, while the CLOSE input enables a closing movement. The
STEP-BY-STEP input enables an alternating opening and closing
movement. Movement stops as soon as the input command stops.
During an opening or closing manoeuvre, movement will stop also
when the command input or the signal from the safety devices is
disabled. During both opening and closing manoeuvres, the activa-
tion of the STOP command will cause the movement to stop imme-
diately. When a movement is stopped, stop the input command
before giving a command to start a new movement.
When one of the automatic modes (“Semiautomatic”, “Automatic” or
“Aut Close Always”) is operational, a command impulse to
the OPEN input causes an opening manoeuvre. A command impulse
to the STEP-BY-STEP input begins an alternating closing and opening
manoeuvre. A second impulse to the STEP-BY-STEP input or to the
same input the started the movement will cause it to stop.

Both in the opening and closing phases, the activation of the STOP
command will cause an immediate stopping of movement and a
short reverse run. If a continuous signal rather than an impulse is
maintained in a command input, a “prevalence” condition will be
generated causing the other command inputs to be disabled

(this

is useful if you need to connect a clock or a Night/Day selec-
tor switch

If an automatic operating mode has been chosen, the opening
manoeuvre will be followed by a pause and then a closing manoeu-
vre. If PHOTO triggers during the pause, the timer will be reset with
a new pause time; if, on the other hand, STOP is activated during
the pause, the closing function will be cancelled and the system will
switch to the STOP mode.
PHOTO will have no effect if it is triggered during the opening
manoeuvre, however if PHOTO is triggered during the closing
manoeuvre, the movement will reverse, pause, and then start to
close again.

5.1) Programmable functions

With the FUNCTIONS dip-switch you can select the various functioning modes and add the functions required according to this table:

Switch 1-2

Off Off

= “Manual” movement, i.e. hand operated

On-Off

= “Semiautomatic” movement

Off-On

= “Automatic” movement, i.e. automatic closing

On-On

= “Aut always close” movement
