LS-102
Description
The LS-102 daylighting controller is a single-zone on/
off switching, closed loop photosensor for interior lighting
applications. The LS-102 will signal a lighting control device
to automatically turn off or turn on the designated interior
lighting based on the amount of daylight present. It has
an advanced digital multiband photosensor, an onboard
microcontroller, and an LCD display. The LS-102 has a 100°
optical cone that cuts off unwanted light, eliminating false
triggering.

OPERATION
ON, OFF, AND DEADBAND SETTINGS
The LS-102 is a self-contained 24 VDC device with an
extended range of 1-1400 footcandles that requires a low
voltage power pack to operate. When the user adjusts the
setpoints, the device will turn lighting systems off when the
ambient light levels exceed the OFF setpoint, and will turn
lighting systems back on when natural light levels have fallen
below the ON setpoint. Because of its automatic calibration
feature, many applications require little or no adjustment of
the settings. The LS-102 can be paired with a low voltage
wall switch to enable manual override or with an occupancy
sensor to enable its ‘hold on while occupied’ feature.
The LS-102 features automatic setpoint calculations. The
device initiates a procedure to select an appropriate value for
the on setpoint. As part of the process, the controlled load is
first turned on for a brief interval to warm up the lamps, and
then switched off. This process is repeated several times.
At the completion of the calibration, a new value for the on
setpoint will have been selected. Other adjustable settings
include deadband and time delay settings. If desired, the
deadband can be adjusted to a value of 25, 50, 75, or 100
percent above the setpoint. The time delay can be adjusted to
3, 10, 20, or 30 minutes.
The LS-102 daylighting controller can be used to control
any type of lighting: incandescent, fluorescent, compact
fluorescent, or HID. The sensors work in peripheral offices,
skylit areas, cafeterias, warehouses, and any other indoor
areas with natural light access.
