MANA DT SMA
POLITEC | INSTALLATION MANUAL - VER.3.1
Make sure that there are no external light sources that
interfere with the correct reading of the signal (gate
photocells, other barriers, infrared etc.), to do this it is
possible to check masking by activating DIP 10.
Check the correct sizing of the power cables.
The system goes into alarm with fog
and rain
Check that the fog disqualification function is active.
Make sure that the power supply of the heaters is greater
than 20 Vac at the barrier terminal board.
In case of very thick fog activate DISQ1.
Make sure that the structure is well sealed and check that
there are not already disturbing elements inside (water,
insects etc.).
Check the alignment accuracy of each individual optic and,
if necessary, carry out the procedure by performing a
complete scan, making sure that there are no light sources
that can influence the calibration.
For more precise alignment, position one side of the
column cover in front of the lenses in order to have two
surfaces interposed between TX and RX to double the
attenuation of the beam.
Repeated false alarms
Check the alignment accuracy of each individual optic and,
if necessary, carry out the procedure by performing a
complete scan, making sure that there are no light sources
that can influence the calibration.
Make sure that the power supply of the heaters is greater
than 20 Vac at the barrier terminal board.
Use the shielded cable for synchronism by connecting the
braiding to the earth.
Check the correct sizing of the power cables.
If possible, increase the intervention time.
The
system
goes
into
disqualification even in the absence
of fog
Make sure that the power supply of the heaters is greater
than 20 Vac at the barrier terminal board.
Check the alignment accuracy of each individual optic and,
if necessary, carry out the procedure by performing a
complete scan, making sure that there are no light sources
that can influence the calibration.
