LEDs
PROBLEM
POSSIBLE SOLUTION
Fuse Blows
- Check fuse rating.
- Check for shorting between
the enclosure and the
input power.
Don’t know
if LEDS are
“ON”
850nm LEDs will have a faint red glow
when “ON”.
940nm LEDs are covert.
Aim the LEDs directly at an IR sensitive
camera to see the lights or wait for the
LEDs to warm up (two minutes).
LEDs are
not “ON”
- Cover the photo sensor to
activate power to the LEDs
( up to 30 seconds delay
for activation ).
- Adjust the photocell’s
variable resistor towards the “ON”
position.
- Adjust power to the LEDs.
LEDs are
not turning
“OFF” when
sufficient
ambient
light is
present
- Make sure the photo
sensor is not covered or
hidden behind any object.
- Adjust the photocell’s
variable resistor towards
the “OFF” position.
The LEDS will stay “ON”
or “OFF” if the adjustments
are at full turn.
