GJD Mini Opal - Testing and Adjustment; Driving a Piezo Buzzer from the A Connection; Walk Test; Dusk Adjustment

DRIVING A PIEZO BUZZER FROM THE A CONNECTION
This conguration can be useful as a temporary measure during your
walk-test. The piezo buzzer will sound every time a detection takes
place.

WALK TEST
The walk test iterates through the following adjustments until the
correct area is covered.
TIP: The eld of view of the mini Opal is affected by the cover.
Always perform the walk test with the cover tted removing the cover
each time you need to make adjustments.
1. Adjust the aim of the sensor, loosen the top and side plastic
wing-nuts and swivel the bracket. Tighten the wing-nuts again
and replace the cover.
2. Congure the eld of view by blanking lens area as necessary.
You may want to blank parts of the eld using the vertical
curtains or by cutting the foil sticker to size. Apply the sticker
to smooth, rear side of the lens.
3. Adjust the range between 8 and 30 metres using the PCB
mounted pot.

DUSK ADJUSTMENT
Adjust the lux level for the day-night setting using the lux PCB
mounted pot.
The S output is factory set to start operating at dusk. That is, when
the light level falls below 5 lux. If the ambient night-time light levels
are higher than 5 lux then the S output will remain inactive and your
lights will not turn on.
• If the light level in your installation is about 5 lux at night (lights
do not operate), increase the light level at which the S output
starts to operate, by turning the lux pot clockwise towards
24HR.
• To set the S output to detect continuously, day or night,
independent of light level, turn the lux pot all the way to
maximum, marked 24HR.
