14. F.A.Q
I can’t calibrate the
columns
o
Make sure that there are no obstacles whatsoever interposed
between RX and TX and that the conformity of the site does not pose
an impediment;
o
Make sure that TX is being tested (orange LED of optic in question
switched on and others turned off);
o
Make sure the connectors are securely attached and that the
configuration of the DIP is correct;
o
Make sure that there are no external light sources that interfere with
the correct reading of the signal (photocell gates, other barriers,
infrared, ...);
After precisely aligned
sensor (light LED
steadily on and
continuously BIP sound)
system remains in alarm
o
Make sure the connectors are securely attached and that the
configuration of the DIP is correct;
o
Verify that optic receiver senses the corresponding transmitter. To
do this, set the AND mode, if the barrier is no longer in alarm obscure
individually each ray finding one that does not generate the alarm
general, this ray is not aligned;
o
Make sure that there are no external light sources that interfere with
the correct reading of the signal (photocell gates, other barriers,
infrared, ...);
With fog or rain, the
system goes into alarm
o
Check that the function of disqualification from fog is active (see pag.
11);
o
Make sure that the structure is properly sealed and check that there
are not already present within disturbing elements as water, insects,
...;
o
Verify the accuracy of the alignment of each optic and in case re-
perform the procedure possibly making a complete scanning that
there are no light sources that can influence the calibration;
o
For a more precise alignment position a side of the column cover in
front of the lens in order to have two surfaces interposed between
TX and RX for doubling attenuation of the beam.
Repeated false alarms
If they are caused by the passage of animals, use either AND, or
increase the intervention time
o
Verify the accuracy of the alignment of each optic and in case re-
perform the procedure possibly making a complete scanning that
there are no light sources that can influence the calibration;
o
To prevent radio interference, use as a link between the wireless
transmitter and barrier a shielded cable with the shield to the negative of
terminal block;
