4. Manually adjust the optics of the
first
TX
expansion board
in
order to display the maximum
voltage value on the tester, i.e.
approx 4 Volts
(voltage values
beyond 4 Volts are to be
considered optimal).
Some multimeters might display
a voltage that is up to 50% lower.
It is very important to direct the
lens towards the
centre
of the
receiving barrier (
RX
) installed
frontally.
Note: It is important to ensure all the
red leds on the RX optics electronics
are switched off. In the event of some
or all of the leds being on, direct the
TX optics until they switch of.
5. Remove the jumper test from the first
TX
expansion board
in the lower section.
6. Repeat the alignment operation in the same way for all the remaining
TX
expansion boards.
Aligning the receiver assembly (receiver)
1. Move the test jumper on the
base
TX
board
to position
ON
.
2. Insert the jumper test in one of the central
TX
expansion boards
to position
ON
.
