9. TROUBLESHOOTING GUIDE – LEDs
PROBLEM
POSSIBLE SOLUTION
Fuse
Blows
- Check the fuse rating.
- Check for shorting between the
housing and the input power wires.
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, or use a mirror to
see the lights through the
EX80/82DXL B/W camera, 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
(up to 30 seconds delay). The LEDS
will stay “ON” or “OFF” if the
adjustments are at full turn.
