UNIT DESCRIPTION
The LMLS-400 is a closed loop photosensor that measures the
ambient light level in order to automatically switch or dim one
zone of lighting. It is part of the Digital Lighting Management
(DLM) system and sends light level signals to control loads
connected to DLM switching or dimming room controllers. The
LMLS-400 has photodiodes with an extended range of 1-1,553
footcandles (fc), and photopic correction to mimic the human
eye, for precise measurement of visible light.
The LMLS-400 operates on Class 2 power supplied to a DLM
local network by one or more DLM room controllers. Plug n' Go
automatic configuration assigns the photosensor to control load 1.
Loads may be reassigned using an LMCT-100. Following a manual
or automatic setup process, the LMLS-400 monitors the ambient
light in the controlled space and works with the room controller(s)
to maintain the design light level. The LMLS-400 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 Photosensor Viewing
Port views the daylight and electric light combined.
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-400 will not
operate properly until the configuration and calibration is
successful.
a. Select the LMLS-400 to be configured, from the
Daylighting menu.
b. Use Zone Setup to select the operating mode for
the controlled zone (Switched, Bi-Level, Tri-Level, or
Dimmed).
c. Assign individual loads to the LMLS-400 controlled zone.
d. Calibrate the LMLS-400 either automatically or manually.
If manual calibration is chosen a light meter will be
required.
e. Adjust Zone Settings and Advanced Settings to meet
specific sequence of operation requirements.
f. Use Test Mode to verify the LMLS-400 operation.
