ENCLOSED YOU WILL FIND

• Light-Sensing Timer

OPERATING DESCRIPTION:

Your Light-Sensing Timer is activated by changes in

surrounding light. For optimum performance, the

Light-Sensing Timer should be positioned in an area

exposed to a strong source of natural light. For indoor

applications, ideal positioning is in a lamp xture located within 4 ft. of a

window or other light source.

Once power is supplied to your Light-Sensing Timer, the control will turn on

at dusk (or when the surrounding light level becomes low enough) and then

turn oﬀ after the selected time period. Once the bulb automatically turns oﬀ,

it will remain oﬀ until the following night. At dusk on the following night, the

Light-Sensing Timer will once again turn on, then turn oﬀ after the user

selected time period. As long as power is supplied to the control, the

Light-Sensing Timer will continue to cycle on and oﬀ in this manner.

INSTALLATION (For use indoors or in enclosed xtures)

1. Turn "OFF" power to light xture.

2. Screw Light-Sensing Timer into light xture.

3. Screw bulb into Light-Sensing Timer.

4. Position control so that the photocell eye faces a strong source of light.

5. Turn "ON" power to light xture (middle setting for 3-way lamp).

Light-Sensing

Timer will begin to operate in 30 to 60 seconds.

OPERATING INSTRUCTIONS

•

Your Light-Sensing Timer has two adjustment features

a) Timing Adjustment - Adjust “Timer” knob as desired to a minimum

setting of approximately one hour to a maximum of approximately six

hours.

b) Sensitivity Adjustment - Adjust “Turn-On” knob to left

(counterclockwise)

for earlier (brighter) activation or right (clockwise) for later (darker)

activation.

•

Once the timing cycle begins, the lamp will remain on for one cycle

duration

regardless of light level.

•

To force on or extend the timing

cycle for additional one to six hours.

a) In dark conditions, turn oﬀ lamp for

approximately 60 seconds, then

turn on. After 15 seconds, light

bulb

will turn on and timing cycle will

begin.

b) In light conditions, completely

cover photocell eye until

light bulb turns on.

ADJUSTMENTS

•

After measuring the length of one

timing cycle, adjust knob according

to preference. Setting the “Timer”

knob to mid-range, will result in a

to 3

hour timing cycle.

•

To adjust the light sensitivity setting, set “Turn-On” knob to center

position.

If lamp turns on before the desired darkness level is reached (i.e. early

dusk),

adjust knob clockwise. If lamp turns on after the desired darkness level is

reached, adjust knob counterclockwise.

Note:

The Light-Sensing Timer requires a certain amount of surrounding

light during the day to reset. Some applications may require initial knob

adjustments to ensure re-set conditions are met so your Light-Sensing

Timer will operate properly. See troubleshooting section for details.

TROUBLESHOOTING

Problem:

Control turns on at dusk during the rst night of operation but

does not turn on at dusk during the second night (or second timing cycle)

of operation. This means the Light-Sensing Timer did not see enough light

during the daylight hours to reset. This problem usually occurs on cloudy

or overcast days when there is no sunlight.

Solution:

Move Light-Sensing Timer closer to a natural light source

and/or adjust the “Turn-On” knob clockwise. Repeat on subsequent nights

if necessary.

Problem: Light-Sensing Timer

does not turn on at all.

Solution:

Make sure power is supplied to light xture. Ensure light bulb is

not burned out. For 3-way lamp xtures, make sure the lamp switch is set

at the middle switch position. The Light-Sensing Timer should turn on after

photocell eye sees darkness or after photocell eye is completely covered.
