WARNINGS!
– The PVC power cable supplied is suitable for indoor installa-
tions.
The final connection of the automation to the electrical mains,
must be performed by a qualified electrician, in compliance
with local standards and the instructions in the section "Tasks
reserved for qualified technicians".
To perform the automation operation and programming tests, insert the
power plug of the control unit (supplied) in a mains socket (fig. 41). If
the socket is far from the automation, use a suitable extension lead.
INITIAL START-UP AND ELECTRICAL CONNECTION CHECK
STEP 8
CAUTION! The following operations described in this manual will be
performed on live electrical circuits and therefore manoeuvres may
be hazardous! Therefore proceed with care.
After powering up the control unit (fig. 41) perform the following opera-
tions, checking conformity of results:
• Immediately after start-up, the red led (fig. 42) flashes quickly for a few
seconds, after which the red and green leds light up alternately; then the
green led turns off and the red led continues flashing at regular intervals
every second (= control unit operating status OK).
CAUTION! - If the red led does not flash as described above, dis-
connect the Control unit from the power supply and carefully check
all connections (refer also to the paragraph "What to do if....").
• If the system is equipped with photocells, check the RX element to
ensure that the led is OFF (= operation OK) or ON (= obstacle present). If
the Led is flashing, this means that the signal is poor and subject to incor-
rect photocell alignment.
• If the system is equipped with a radio control keypad, check operation
with reference to the relative instruction manual.
