UNIT DESCRIPTION
The LMLS-500 is an open loop photosensor that measures
daylight in order to automatically switch or dim up to three zones
of lighting. It is part of a Digital Lighting Management (DLM)
system and sends light level signals to control loads connected
to DLM switching or dimming room controllers. The LMLS-500
has a photodiode with an extended range of 1-6,553 footcandles
(fc) and photopic correction to mimic the human eye for precise
measurement of visible light.
The LMLS-500 operates on Class 2 power supplied to a DLM
local network by one or more DLM room controllers. Once set
up, the LMLS-500 uses switching or dimming setpoints and other
control parameters to manage the light levels throughout the day
regardless of changing daylight contribution.
Sensor Installation and Configuration Overview
1. Mount the photosensor so that the Daylight Viewing Port
directly views the daylight entering the space through
a window or a skylight. See Placement Guidelines and
Mounting the Photosensor.
2. Complete all wiring and turn ON power to the room
controller.
3. Use the LMCS-100 or LMCT-100 configuration tool to
complete the configuration process. The LMLS-500 will not
operate properly until the configuration and calibration is
successful.
a. Select the LMLS-500 to configure and select Zone
Setup.
b. Choose the desired number of zones (1-3), then select
the operating mode for each zone (Switched, Bi-Level,
Tri-Level, Dimmed).
c. Assign individual loads to each of the configured zones.
d. Calibrate the LMLS-500. Use a light meter to measure
the light level at each zone with the lights ON and OFF to
determine the relationship between the light level at the
task and light level at the LMLS-500.
e. Adjust Zone Settings and Advanced Settings to meet
specific sequence of operation requirements.
f. Use Test Mode to verify the LMLS-500 operation.
