OPERATION
Adjusting the duration time: The length of time that
the light remains switched on after activation can be
adjusted from 5 seconds to 5 minutes. Rotating the
TIME knob from + to – will reduce the duration time.
Note: Once the light has been triggered by the PIR
sensor, any subsequent detection will start the timed
period again from the beginning.
Adjusting the LUX control level: The LUX control
module has a built-in sensing device (photocell) that
detects daylight and darkness. The (R) position indicates
that the light will work day and night. The (ƒ) position
indicates that the light will only work at night. You can
control when the light comes on at a desired light level
by adjusting the LUX knob.
Adjusting the sensitivity: The sensitivity refers to
the maximum distance which the PIR sensor can be
triggered by body movement. Turning the SENS knob
from + to – will decrease the sensitivity.

SYMPTOM POSSIBLE CAUSE
Lights will not come on. 1. Light switch is turned off.
2. Fuse is blown or circuit breaker is turned off.
3. Daylight turn-off is in effect.
4. Incorrect circuit wiring, if this is a new installation.
5. Light control aimed in wrong direction.
Lights come on in day- 1. Light control may be installed in a relatively dark
light.
2. LUX dial is turned toward daylight (R).
Lights come on for no 1. Light control may be sensing small animals or auto-
apparent reason.
2. Sensitivity (SENS) dial is set too high.
Lights stay on continu- 1. A lamp head is positioned too close to the light control
ously.
2. The light control may be picking up a heat source

Least Sensitive
Note: If fixture is mounted higher than 8 ft. (2.4 m),
aiming the sensor down will reduce coverage distance.
The detector is less sensitive to motion directly towards it.
SOLUTION
1. Turn light switch on.
2. Replace fuse or turn circuit breaker on.
3. Recheck after dark.
4. Verify wiring is correct.
5. Re-aim light control to cover desired area.
1. The fixture is operating normally under these condi-
tions.
2. Turn LUX dial toward night (ƒ).
1. Re-aim light control.
2. Reduce sensitivity.
1. Reposition the lamp head away from the light control
or nearby objects.
2. Reduce sensitivity.
1. Reposition the lamp head away from the light control
or turn LUX dial toward night (ƒ).
2. Reposition light control.
