A.q - Elkron EL250RT Notice D'installation Et D'utilisation

I cannot align the columns
After precise alignment of
the sensor (the LED
remains on, with a
continuous beep) the
system remains in alarm
The system goes into
alarm when there is fog or
rain

20 F.A.Q
Check that there are no obstacles of any kind located between RX and TX and the
conformity of the site does not present an impediment;
Make sure that the TX is in test phase (orange LED lit on the optics in question and
the others off);
Make sure there are no external light sources that may interfere with the proper
reading of the signal (photocells on gates, other barriers, infrared devices...);
For barriers with multiple devices positioned along the same line, the TXs not being
aligned must be turned off; to do this, the four TX DIPs must be set to the ON position
(Section 12), ensuring that the orange LEDs are off;
Make sure the connectors are properly inserted and that the DIP configuration is
correct;
Check that the power supply to the terminal block is sufficient;
Use the shielded cable for the power supply, connecting the sheath to ground (it is
recommended, in case of persistent problems, to connect the alarm and power
supply/tamper with two separate shielded cables);
Check that the power supply cables are the right size
Note: remember to reactive the optics once the alignment operation is finished.
Make sure the connectors are securely inserted and that the DIP configuration is
correct;
The ALARM LED is lit on the TX terminal column instead of the SYNC LED;
Check that there is synchronization, with the yellow SYNC-RX LED on (see chap. 12),
otherwise the alarm will not be constant; then recheck the connections (see section
8), making sure that the terminal block is properly inserted;
Determine which receiver optics are not picking up the corresponding transmitter. To
do this, set the AND mode; if the barrier is no longer in alarm, cover each beam
individually to find one that does not generate the general alarm: this beam is not
aligned;
Make sure there are no external light sources that may interfere with the proper
reading of the signal (photocells on gates, other barriers, infrared devices...);
Use shielded cable for the synchronization, connecting the sheath to the ground;
Check that the power supply cables are the right size.
Check that the fog disqualification function is active (see section 13);
Make sure the power supply to the heaters is more than 20 Vac in the terminal
block on the barrier.
In the case of very thick fog, activate DISQ1 (see section 13);
Make sure that the structure is well-sealed and check that no disruptive elements
(water, insects...) are present inside it;
Check that each of the individual optics is precisely aligned and repeat the procedure
if necessary, performing a full scan and ensuring there are no light sources that may
affect the calibration;
For a more precise alignment, position one side of the column cover in front of the
lenses so as to have two surfaces interposed between TX and RX to double the beam
attenuation.
