Even if the anemometer turns at a speed exceeding the
threshold adjusted with the wind trimmer, the motors con-
nected to it do not carry out the “up” command (
▲
).
Check the power voltage on the connection wires between sensor and
motor, it should be around 24±5 Vdc. If you measure a different value,
check the connections, see whether the motor is switched on and run-
ning; if multiple motors or control units are connected to the same sen-
sor, make sure that the wires are connected properly according to their
colour coding or control unit terminals.
Though the connections are OK and the voltage reading on
the connection between sensor and motor is approximately
24±5 Vdc, when the anemometer turns the “up” manoeuvre
(
▲
) is not carried out.
The threshold adjusted with the wind trimmer must be exceeded for at
least 3 seconds, rotate the anemometer at a suitable speed, otherwise
try to adjust the wind trimmer to the minimum value.
The wind response test has been carried out successfully,
unlike the sun response test.
The sun protection “down” manoeuvre is ordered only when the pro-
grammed threshold is exceeded for at least 2 minutes. Try switching the
motor off and back on again, then repeat the test. You could also try to
set the sun trimmer to the minimum value. If the problem persists, check
that the sun sensor hasn't been disabled (see table A, No. 4) with a
switch connected to the terminals of the grey wires. Check if a “sun-off”
command has been sent to the motors with ERGO4 and PLANO4 trans-
mitters.

5) Diagnostics
All sensor conditions are suitably indicated by a two-colour led “C” on the lower part of the sensor. Indications concerning the said conditions are list-
ed in table A below.
NOTES
• If both the wind threshold (No. 2) and the sun threshold (No. 3) are exceeded, only the red led lights (wind overrides)
• The “anemometer inoperative warning signal” function (No. 5), indicates that the sensor has not detected wind in the past 24 hours.
• The “sun sensor inoperative warning signal” function (No. 6), indicates that the sensor has not detected any variation in the light intensity in the past
24 hours.
• To check if a fault has really occurred simply rotate the blades of the anemometer (No. 5) or change the light intensity of the sensor (No. 6), cover-
ing it with the hand for example. If the warning signal persists, this probably means that there is a fault.
1.
No threshold exceeded and no warning signal: led off.
2.
Wind threshold exceeded: red led on.
3.
Sun threshold exceeded: green led on.
4.
Sun sensor disabled: green led flashing at intervals of 1 second.
5.
“Anemometer inoperative” warning signal: red led flashing at intervals of 0.25 second.
6.
“Sun sensor inoperative” warning signal: green led flashing at intervals of 0.25 second.
