N.B.: the fixed buzzer sound has a maximum duration of 3 minutes.To obtain a good alignment it is
necessary to complete a FULL rotation on the horizontal axis of the RECEIVER optic, thus performing
the SCANNING of the optical signal.This operation is very useful to understand if the alignment of the
optics is taking place directly on the same axis and not through reflection, therefore deceptive,
because the signal value is much lower, despite having reached the hypothetical maximum alignment
signal.
•
The partial or total misalignment condition is signalled by the infrequent flashing of the LEDs and
by the non-continuous whistle of the buzzer.
•
After calibration, tighten the horizontal adjustment screw, and exit the test function by pressing
the TEST button on the TX and RX optics for 3 seconds.
•
Repeat all the operations on each beam of the barriers that make up the system.
At the end of the operation, remove the screen which acts as an attenuator, making sure to have
found the optimal value.
N.B.:If the barriers work with optical synchronism,
to be absolutely certainty that the alignment of the
optics is correct (and therefore there are no false
alignments due to other infrared sources, such as
gate photocells), cover the TRANSMITTER optic with
your hand: if the RECEIVER continues to give a
continuous beep, it means that it sees another
infrared source that must be turned off and
eliminated.
