With fog or rain, the
system goes into
alarm
o
Check that the function of disqualification from fog is active (see chap. 12);
o
Make sure the power of the heaters is higher than 20 Vac to the
terminal
block
of the barrier.
o
In case of very thick fog activate DISQ1 (see chap. 12);
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
o
If they are caused by the passage of animals, use either
AND, BEAM 1
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
Make sure the power of the heaters is higher than 20 Vac to the
terminal
block
of the barrier.
o
Use two different shielded cables for power and sync, connecting the shield
to the ground;
o
Check the correct sizing of the power cables;
o
If the system uses a switching power supply replace it with corresponding
linear to avoid electrical interference from the network, it is recommended
that the power supply
LAR22
.
o
If you can increase the intervention time;
The system goes into
disqualification even
without fog
o
Make sure the power of the heaters is higher than 20 Vac to the
terminal
block
of the barrier..
o
Verify the accuracy of the alignment of each optic and in case re-perform
