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;
Note: Remember to enable the optics once finished alignment.
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
Ensure that power on the terminal board is enough;
o
Use shielded cable for power supply; connecting the shield to the ground (is
recommended in case of persistent problem to connect power and alarm /
tamper with two separate, shielded cables);
o
Check the correct sizing of the power cables;
o
Make sure that there are no external light sources that interfere with the
correct reading of the signal (photocell gates, other barriers, infrared, ...);
o
For barriers with multiple devices positioned on the same line it is necessary
to turn off TX on which you are not performing the alignment operation; to
do this you must move the four DIP TX (Cap. 11) in the ON position,
making sure that the orange LED are off;
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
.
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
Make sure there is synchronism, led SYNC-RX Yellow On (see chap. 11),
otherwise the alarm will not be constant, then check the connections (see
Sec. 7) making sure that the terminal block is well inserted;
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, ...); to
do that you can check a masking activating DIP 10 (
antimasking
, see chap.
10 and 12);
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
.
