INSTALLATION
Fix the barriers so that they are aligned and wire the terminal block.
Both on the receiver (RX) and on the transmitter (TX) check that all the dip switches are in the OFF position and power the
modules.
ALIGNMENT (SIGNAL LEVEL CONTROL)
Control the red LED on the receiver module, if it is off and the buzzer does not sound (to enable the buzzer, set dip switch 9 to
ON) the barriers are aligned. If the LED is on and the buzzer sounds, follow the procedure below:
On the receiver, set dip switch 8 to ON and then dip switch 7 to ON,
NOT BEFORE 7 AND THEN 8.
Note: this is the procedure to follow even if you only want to check the signal level with aligned modules.
A signal value will be shown on the display, then orient the receiver's optical unit in the direction of the transmitter and vice
versa until the LED on the receiver module is off and the buzzer stops ringing.
The values are to be considered optimal if included between 2.6 to 3.6 V, if the LED goes off even below 2.6 V it means that the
barriers are communicating, if possible, however, try to reach a value between 2 anyway, 6 and 3.6 V.
For vertical adjustments, act on the adjustment screw, while for horizontal adjustments, rotate the bracket (see IMAGE 1). If
necessary, use the viewfinder to help you (see IMAGE 2).
Once the modules are aligned, set dip switch 8 to OFF and dip switch 7 to OFF, NOT BEFORE 7 AND THEN 8.
FREQUENCY CHANGE:
To change the frequency which by default is 1 (dip switches 1,2 and 3 in OFF),
follow the procedure below:
First on the RX module and then on the TX module, using the dip switches 1,2 and 3
set the frequency, see the table on the side for the 8 possible combinations.
First on the RX module and then on the TX module confirm the frequency
by setting dip switch 7 to ON and after a second repositioning it in OFF.
ATTENTION: NEVER LEAVE DIP SWITCH 7 ON.
SENSITIVITY ADJUSTMENT:
Turn the trimmer located on the right side of the receiver to adjust the sensitivity.
