1. Check that lamps and fixtures
work. Compare wiring to the wiring
diagram in this manual. Check that
the power is on.
2. If installing during daylight,
remember that the sensor will
provide 5 minutes of Test Time after
power is turned on. After 5 minutes,
the sensor will switch to Automatic
Mode and will not work during
daylight if the photocell control is
turned to the night only position
(moon symbol).
If you require 5 more minutes of
Test Time, turn the power off for
at least 10 seconds and back
on again.
If you require the sensor to operate
both day and night, turn the center
control knob counterclockwise to
the sun and moon symbol.
3. Check that lights from another
source, such as adjacent porch
lights, garden lights or street lights
are not in the sensor’s view. The
sensor’s photocell may detect the
light and deactivate “daylight”.
If you desire the sensor to operate
in higher ambient light levels, turn
the photocell control (center knob)
toward the sun symbol.
4. Was sensor wired hot? If so
circuitry may have been damaged.
1. Check if sensor is being “tricked”
by reflected light. If lights controlled
by the sensor shine or reflect into
the photocell (located behind the
lens) the unit will go on briefly, see
its own light, and turn off “thinking”
that it is daytime:
Problems:
Lights reflect into photocell, or
Lights shine directly into photocell
Solution:
Adjust photocell control (center
knob) slightly counterclockwise, to
allow operation at higher ambient
light levels. Alternatively, move the
lights or reflectors or mask the lens
in the direction of the lights and/or
reflections.
2. Check if “R” lamps, non-reflec-
tor “A” lamps or self-ballasted PL
lamps are being used in a non-
enclosed lampholder. If so, switch
to reflector PAR floodlight lamps
or Quartz floods so the sensor is
not affected by stray light. If using
PAR floodlights, consider using
lower wattage, energy saving
lamps.

Lights Do Not Turn On
Lights Turn Off Too Quickly
