LCE-211-120

LCE-211-277

DESCRIPTION

The LightSaver

LCE-211 controller provides control of exterior lighting.

The LCE controller automatically turns lights off when daylight

contributes enough light to the space, and turns lights on as artificial

lighting is needed — conserving lighting resources and energy costs.

An ON/OFF time delay provides a “cushion” of time that eliminates

on/off light cycling due to brief variations in daylight (i.e., clouds passing

or windshield reflections). The LCE-211 works with the LS-071C

photocell, which reads the ambient light levels.

OPERATION

Note: The controller has one normally closed (NC) contact and one

normally open (NO) contact. The operations described below

assume that the NC contact will be used.

Turning Lights On:

When the daylight level drops below the setpoint, the LED on the front

of the controller module will turn off. After a time delay of approximately

one minute elapses, the lights will turn on.

Turning Lights Off:

When the daylight level rises above 110% of the setpoint, the LED on

the front of the controller module will turn on. After approximately one

minute has elapsed, the lights will turn off.

Fail Safe Operation:

When power to the controller is restored following a power interruption,

the lights will turn on. The contacts will close for one minute before the

controller resumes normal control.

INSTALLATION

1. Mount the controller in an electrically rated panel. In dry locations,

use at least a NEMA 1 enclosure. For exterior locations, use either a

NEMA 3R or NEMA 4 enclosure.

2. The maximum wire distance to the LS-071C Photocell is 250 feet

using 18AWG cable. Use 2-conductor cable, Belden 8461 or

equivalent.

3. The LS-071C has a watertight enclosure, but it is recommended that

it be mounted in a protected location, such as under the eaves of a

roof.

≠ CAUTION: INSTALLATION MUST BE PERFORMED ≠

BY A QUALIFIED ELECTRICIAN ONLY.

FOLLOW PROPER SAFETY PROCEDURES AND

BUILDING CODES THAT APPLY.

LCE CONTROLLER MODULE ADJUSTMENTS

The following adjustments must be made to the LCE controller to

ensure proper operation.

Setpoint dials:

The setpoint is the threshold value which, when the daylight level drops

below this point, triggers the control signal to turn lights on.

The setpoint should be selected based on the design requirements of the

application. Review construction plans or check with engineering

consultants to determine the proper setpoint. If neither of these sources is

available, use the following typical design conditions as guidelines:

• Building entrance 5 footcandles

• Open parking lot

– lighting for cars .5 - 2 footcandles

– lighting for pedestrians .8 - 4 footcandles

With a small screwdriver, turn the setpoint dials on the LCE Controller to the

determined value. When viewing the setpoint dial, refer to the .2 to 20

footcandle ranges.

LED:

The LED turns off when the light level falls below the setpoint, and

remains off until the daylight level rises above 110% of the setpoint.

Note

: Although the LED can turn on before the time delays are

satisfied, the lights will not turn on or off until the time delays

are satisfied.

TROUBLESHOOTING

The controller will not turn off lights:

1. Verify that the LCE module is powered up.

2. Verify that the photocell is connected properly.

The controller will not turn on lights:

1. Verify that the photocell wiring has not shorted.

2. Verify that the photocell is not exposed to any sources of artificial

light.
