5. LED DIRECTIONAL AND POWER
ADJUSTMENTS
If the LEDs need to be adjusted for beam
spread, the Camera/LED Array Assembly does
not need to be removed from the housing. The
adjustment can be done by hand.
The EX3xN can be powered while making
adjustments, but make sure the power cable is
not pinched or chafed during this procedure.
Cover or adjust the photo-cell to turn the LEDs
"ON" (850nm LEDs will have a slight red glow
while 940nm LEDs are covert). Adjust the LED
power if they are too bright.
Refer to Figure 5-1 on page 15.
In some cases it may be necessary to bend the
LEDs slightly for better beam spread. Do not use
your fingers for this function. Use a flat wooden
object and gently push the outside row of LEDs
inwards or outwards. The camera should be
"ON" while this adjustment is in progress.
