3. Connect the tester to the test point of the first
RX
expansion board
in the lower section
using the small (red-black) cable supplied.
4. Move jumper MODE on the
RX
expansion
board
to position
TEST
.
5. Manually adjust the optics of
the first
RX
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
transmitter barrier (
TX
) installed
frontally.
6. Repeat the alignment operation in the same way for all the remaining
RX
expansion boards
.
7. After completing all the alignment operations, move the jumper of the
base
TX
board
to position
OFF
.
8. Move all the jumpers of the
TX
expansion boards
to position
OFF
.
9. Move all the jumpers of the
RX
expansion boards
to position
NORMAL
.
10. Models with two lenses: verify that the barrier generates an alarm signal when
each assembly with two lenses is covered.
Models with one lens: verify that the barrier generates an alarm signal when each
assembly with one lens is covered.
