Troubleshooting Guide
Problem Possible Cause Solution
The light will not
come on.
□ The light switch is turned off. □ Turn the light switch on.
□ No power, the fuse is blown or
circuit breaker is turned off.
□ Replace the fuse or turn the circuit breaker
on.
□ Daylight turn-off (photocell) is in
effect. When the “ON-TIME” setting
is in the 1, 5, 20 minutes position,
light xture only operates after
dark.
□ Recheck after dark. Photocell picking up
too much light. If there are any other light
sources nearby - especially if they are below
this xture - they could be triggering the
photocell in the xture.
□ The circuit wiring is incorrect (if
this is a new installation).
□ Verify the wiring is correct.
□ The motion sensor is aimed in the
wrong direction.
□ Re-aim the motion sensor to cover the
desired area.
□ The outside air temperature is
close to the same as a person’s
body heat.
□ Increase the “Sensitivity” setting.
The light comes on
during the day.
The motion sensor maybe installed in a
relatively dark location.
Relocate the light xture.
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 reected from other
objects and may be turning the
motion sensor on and off.
□ Decrease the “Sensitivity” setting or reposi-
tion 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, uorescent
lighting, GFI outlets, etc).
□ “Smart Meter” nearby. Motion sen-
sor 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.
