11. TROUBLESHOOTING GUIDE – LEDs
PROBLEM
Fuse
Blows
Don't
know if
LEDS are
"ON"
LEDs are
not "ON"
LEDs are
not turning
"OFF"
when
sufficient
ambient
light is
present
POSSIBLE SOLUTION
- Check the fuse rating.
- Check for shorting between the
housing and the input power wires.
- 850nm LEDs will have a faint red
glow when "ON". 940nm LEDs are
covert.
- Aim the LEDs directly at an IR
sensitive camera, or use a mirror to
see the lights through the EX30
camera, or wait for the LEDs to
warm up (two minutes).
- 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.
- Make sure the photo sensor is not
covered or hidden behind any
object.
- Adjust the photocell's variable
resistor towards the "OFF" position
(up to 30 seconds delay). The LEDS
will stay "ON" or "OFF" if the
adjustments are at full turn.
