ELECTRICAL CONNECTIONS

Warning!
– Incorrect connections could cause failures and hazardous situations.
– A single-pole mains disconnection device with a contact gap of at least 3 mm
must be used when making the electrical connections (e.g.: disconnecting
switch, plug and socket, etc.). The connection devices are not supplied with
the product.
– The connections indicated in this manual must be fully respected; if in doubt,
do not try to experiment but consult the relevant technical specifications which
are also available on the web site www.niceforyou.com .
Refer to the electrical layout in Fig. 8 for the connections. The tubular motor
power supply cable has 4 wires:
– Brown: = Up electrical phase;
– Black: = Down electrical phase;
– Blue: = Common (normally connected
to the Neutral);
– Yellow-Green: = Ground (protective
electrical bonding).
Once the connections have been made the up and down movement of the
roller must be verified, because at this point the movements depend on the
side in which the motor has been installed in the roller. If necessary the direction
of each movement can be modified by inverting the Brown and Black wires
(the two electrical phases of the motor are completely interchangeable in as
much that each rotates in a specific direction).

4.1 – PROGRAMMING WARNINGS
• Signals emitted by the motor
– the motor executes 1 very brief interruption at the start of the manoeu-
vre and then resumes movement = only 1 limit position is memorised
– the motor executes 2 very brief interruptions at the start of the manoeu-
vre and then resumes movement = no limit position is memorised
– keeping the control key pressed ("hold-to-run" mode) the movement is
started but is interrupted after a short interval without completing the
manoeuvre = the tubular motor has entered "emergency" mode and the inter-
vention of a specialist technician is required to eliminate the fault
4.2 – LIMIT POSITION PROGRAMMING
Limit positions "0" and "1" (fig. 9) are the standard positions that the roller shut-
ter/ awning takes up at the end of the Up ("0") or Down ("1") manoeuvre.
The programming of the limit switch positions can be performed in three differ-
ent ways. The most suitable choice must be made by evaluating the presence
or absence of devices on the roller shutter/awning that limit or "block" its move-
ment. Roller shutters for example have opening stop "caps" that limit roller
shutter maximum opening, and/or "burglar-proof springs" that prevent roller
shutters from being lifted when fully closed.
Therefore "0" and "1" positions can be programmed differently, depending on
the presence or absence of these mechanical stops (caps and/or springs), via
one of the following 3 procedures.
CAUTION! – Perform only one of the 3 procedures below. If the system is
already programmed with one of these procedures and a different proce-
