3.3 - Mapping the Up and Down movements to
their respective command buttons (
s
and
t
)
After completing the connections, supply power to the motor and carry out some
movements
(*)
to verify if the Up and Down movements of the roller shutter are
correctly matched to their respective symbols
s
and
t
found on the command
buttons. If not, change the connections on the push button panel by reversing the
Brown
and
Black
wires.
(*) Note
– When the Up and Down limit switches have not yet been programmed,
the roller shutter will never stop automatically but will interrupt its movement only
when the control button is released.
PROGRAMMING AND ADJUSTMENTS
4
4.1 - General warnings about performing the pro-
cedures
– All the programming and adjustment operations must be carried out with the Nice
TTU programmer (
Fig. 5
). Alternatively you can also use a two-button push button
panel, as long as this allows you to press the two buttons at the same time and al-
lows the buttons to return to their previous position, when they are released.
– The limit switch must be adjusted after installing the motor in the roller shutter and
connecting it to the power supply.
– Before starting any programming, move the roller shutter to an intermediate posi-
tion, away from the Up and Down limit switches.
– Scrupulously comply with the time limits indicated in the procedures.
– During programming the motor performs a certain number of
brief movements
,
as a “response” to the command sent by the installer. Count these movements
regardless of their direction. The movements are indicated in the procedures with
a number followed by the symbol
.
– The electronic system that controls the roller shutter’s movement at all times can
automatically stop the motor when the roller shutter reaches a certain position (or
“height”) programmed by the installer. The positions are shown in
fig. 6
as follows:
position “0” = UPPER
limit switch (roller shutter completely retracted);
position “1” = LOWER
limit switch (roller shutter completely extended).
4.1.1 - Report messages given by the motor
The motor repeats the report message on the status of the installation by perform-
ing some movements when a manoeuvre is commanded. To understand the signifi-
cance of these movements read
Table A
.
TABLE A
– Movement signals
No. of MOVEMENTS
Meaning
0 movements (START & STOP)
= 2 limit switches programmed.
1 movement (START & STOP)
= 1 limit switch programmed.
2 movements (START & STOP)
= no limit switch programmed.
