Troubleshooting Guide

Problem Possible Cause Solution
The light cycles on
and off.
□ Photocell has not had time to calibrate
for differences between daylight /
darkness. It will think its own light
is sunlight and turn off after a short
period of time.
□ Apply power to the xture for at least an
hour before nightfall.
□ Heat or light from the lamp heads
may be turning the motion sensor on
and off.
□ Reposition the lamp heads away from the
motion sensor.
□ Heat is being reected from other
objects and may be turning the motion
sensor on and off.
□ Decrease the “Sensitivity” setting or
reposition the motion sensor.
□ Electronic interference on the same
circuit is overriding the sensor.
□ Install the light xture on a circuit without
motors, transformers, or uorescent bulbs
(ceiling fan, garage door opener, uores-
cent lighting, GFI outlets, etc).
□ “Smart Meter” nearby. Motion sensor
false triggered by transmission used
by smart meter.
□ Move xture away from the meter.
The light turns
off too late in the
Dusk-to-Dawn
setting.
The light xture may be installed in a
relatively dark location.
Relocate the light xture or use the 3 hour or
6 hour setting.
The light stays on
longer than the
time set.
The timer resets each time motion is
detected. If motion reoccurs before the
timer elapses, the light will remain on
because the timer has re-started.
The light xture is operating normally.
Sensitivity
changes without
any adjustment
made.
Sensitivity will vary depending on weather
conditions. Infrared sensors detect a
change in ambient temperature. Sensor
is less sensitive when body temperature
and the ambient temperature are about the
same (summer).
Adjust sensitivity setting accordingly.
