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 1-6,553 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.

PLACEMENT GUIDELINES
The LMLS-400 switches or dims electric light in
response to daylight. It is important to select a location
where the daylight is representative of the daylight
throughout the controlled zone. The photosensor must
not directly view either the daylight source (window) or
the electric lights, but instead should see the light from
both, reflected from the work surfaces.
When the primary source of daylight is a window
(sidelighting), the LMLS-400 is typically ceiling mounted
within the daylit zone which extends 12 feet or less in
from the window. Figure 1 shows a typical placement
location for a sidelit application.
IR COMMUNICATION
If the photosensor is mounted at ceiling heights greater
than 20’, communication with the photosensor must
be through another IR enabled DLM device such as an
occupancy sensor or a wallswitch.
Infrared signalling can be affected by high ambient light
such as direct sunlight, floodlights, and some halogen or
fluorescent lamps, as well as plasma screens.
Be sure to point the remote at a DLM IR enabled device
that is within range. To test, see if you can put the local
network into Push and Learn™ (PnL) mode using the
remote from your current position.
• Ifnotsuccessful,moveclosertotheIRenabledlocal

• Ifstillnotsuccessful,theIRlensesontheDLMdevices
may be dirty. Clean the lenses with a soft material such
as an eyeglass lens cleaning cloth.
WARNING: Do not use the DLM Local Network
to control loads other than lighting if the
load is not in view of a person at all control
locations. Do not use DLM to control any
load that might be dangerous or cause a
hazardous situation if accidentally activated.

CONNECT THE LMRJ CABLE
The LMLS-400 receives power and communicates with
other DLM devices through a LMRJ cable that plugs into
the RJ45 socket on the end of the unit.
LMRJ cable
WARNING: Never connect the DLM Local
Network to a computer’s Ethernet port;
never connect an Ethernet cable to a DLM
device – DLM is not compatible with Ethernet.
MOUNTING THE PHOTOSENSOR
In most applications, the unit will be mounted through
a ceiling tile, with only the lens being visible from inside
the room; the remainder of the unit will rest on top of
the tile. The alternate mounting approach permits the
unit to be affixed to hard surface. In these surface-mount
applications, an accessory plastic mounting bracket is
required. An accessory for mounting the unit to a J-Box
is also available. The device has an adjustable head to
accommodate multiple mounting methods and building
materials or fixture walls.

OPERATION
The LMLS-400 communicates with all other Lighting
Management devices connected to the DLM Local
Network. It is dependent on a DLM Room Controller
(LMRC-100 series for On/Off switched loads, LMRC-200
and -300 series for On/Off switched loads and dimming
capable loads), DLM Switches for override control, and
DLM Occupancy Sensors for motion detection.

OPERATING MODES
Plug n’ Go
The default operating mode for the LMLS-400 is
Plug n’ Go™ (PnG). Upon initial power up, the system
automatically takes inventory of the devices on the DLM
Local Network and allows immediate operation of devices
in the most energy efficient manner. When only one
LMLS-400 is found, it is automatically assigned to Load 1.
Based on the attributes of the room controller, the LMLS-
400 will configure itself to Switching or Dimming Mode.
Push n’ Learn
Push and Learn™ (PnL) mode provides for remote load
binding and configuration within the room, without
requiring direct access to the Room Controller(s). While
the LMLS-400 must be configured through the use of a
configuration tool (e.g., LMCT-100), the CONFIG button at
the back of the product can be used to force the system
into or out of PnL mode, and/or to step to the next load in
sequence, when configuring devices other than the
LMLS-400.
Confirmation of Load Binding
To provide a confirmation of load bindings after
installation, a quick press using a paper clip on the USER
button sequences through three states:
1st press - all controlled loads forced ON at 100%
2nd press - all controlled loads forced OFF at 0%
3rd press - exit load binding confirmation mode and
resume normal control. (Confirmation mode cancels
automatically after 5 minutes if no further action is taken
after the 1st or 2nd press.)
Test Mode
In Test Mode, time delays are reduced to 5 seconds (to
create near-immediate reactions to changes in measured
light levels), and the ramp rate increases to 20%/second
(to cause the changes to be immediately visible).
To activate Test Mode, press and hold the USER button
for 2 seconds or use a configuration tool. If not cancelled
by the user, the controller automatically exits Test Mode
after 5 minutes.
User Override of Levels Set by Daylighting
Control
The electric light levels of loads
configured for daylighting control can
be adjusted from DLM wall switches,
within limitations established by
LMLS parameters that are set using
the Advanced Settings screen of the
LMCT-100.
The light level can always be reduced (by turning off loads
in a switched zone, or by lowering the level of loads in a
dimmed zone) without restriction. When a load is dimmed
down from its daylighting-permitted level, the new level
set becomes the maximum electric light level for that load
(a “cap” level), regardless of daylight contribution, until the
load is turned off and back on again, or until the level is
adjusted upwards. If a load has been dimmed, a single tap
on the top of a controlling switch’s rocker will return the
level to the maximum allowed by daylighting at that time,
and cancel the level restriction (“cap”) set by the earlier
user adjustment.
Increasing the light level above that set by daylighting is
possible only if Allow Override is set to Yes (the default is
No). For switched modes, this means that the loads can
be turned on even when the present ambient light level is
above the On Setpoint. In the case of dimmed mode, a load
will turn on and adjust to its daylighting-permitted level,
but a subsequent tap on the top of a controlling switch will
increase the level to maximum. In either mode, the affected
loads will be temporarily removed from daylighting control,
and be placed in an “override” state. The levels of the
overridden loads can be changed or adjusted, and they will
not return to daylighting control unless they are turned off
and back on again (for example, by a cycle of occupancy).
If the Override Time parameter is changed from its default
(Infinity) to a fixed time (e.g., 1 hour), all loads presently
overridden will return to automatic daylighting control after
the selected time period lapses.
Any loads not affected by the switch actions causing the
override will continue to be controlled by daylighting;
overrides occur on a load-by-load basis.
If any daylighting loads are presently overridden, the blue
LED in the sensor head will flash once every four seconds.
To provide the ability to set arbitrary light levels in Dimmed
applications, a switch with a dimming control rocker (e.g.,
LMDM-101 or LMSW-105) should be used.
Scene Control and Daylighting
Setting a new light level using a scene switch is possible,
provided Hold Off is set to No (default). Such a light level
change is not considered an override. If daylighting control
is active when the new scene is selected, daylighting
control suspends until the new scene is displayed, and then
resumes, with the new light level established by the scene
as the maximum electric light level (“cap” level), on a load-
by-load basis, until a subsequent user action changes the
level. Any daylighting loads not included in the scene will
continue to operate as before the recall.
Optionally, daylighting control can be temporarily disabled
for any loads on which a scene has been recalled. If Scenes
Stop DL is set to Yes, daylighting control for a load affected
by a scene will not resume until the level of the load is
changed by another user action, or the load is turned off
and on again.

CONFIGURATION
The configuration process
establishes the appropriate
parameters for operation. This
is done through the use of an
LMCT-100 configuration tool.
If no configuration steps are
taken, the sensor will use its
default values for setpoints.
The LMCT-100 Wireless IR Configuration Tool is a
handheld tool for setup and testing of WattStopper
Digital Lighting Management (DLM) devices.
It provides wireless access to occupancy and
daylighting sensors for setup and parameter changes,
WattStopper Push n’ Learn™ (PnL) technology for
load configuration, switch and dimmer assignment
and operating parameter changes. The LMCT-100’s
display shows menus and prompts to lead you through
each process. The navigation pad provides a familiar
way to navigate through the customization fields. The
LMCT-100 allows modification of the system without
requiring ladders or tools; simply with a touch of a few
buttons.
Operation
The LMCT-100’s IR transceiver allows bi-directional
communication between DLM devices and the
LMCT-100. Simple menu screens let you see the
current status of the system and make changes. It can
change any of the DLM occupancy sensor parameters
such as sensitivity, time delay and more. With the
LMCT-100 you can also change load configurations,
without any new wiring.
For systems including the LMLS-400 Daylighting
sensor the LMCT-100 can also set or change the
daylight level parameters. The LMCT-100 can change
dimming system options such as scene assignments,
ramp rates and other options not available through
the standard user interface.
Batteries
The LMCT-100 operates on
three standard 1.5V AAA
Alkaline batteries or three
rechargeable AAA NiMH
batteries.
The battery status displays in the upper right corner
of the display. Three bars next to BAT= indicates a full
battery charge. A warning appears on the display when
the battery level falls below a minimum acceptable
level.
To conserve battery power, the LMCT-100
automatically shuts off 10 minutes after the last key
press.
Navigation
You navigate from one
field to another using
(up) or (down) arrow
keys. The active field is
indicated by flashing
(alternates between yellow
text on black background
and black text on yellow
background).
Once active, use the Select button to move to a menu or
function within the active field.
Value fields are used to
adjust parameter settings.
They are shown in “less-
than/greater-than” symbols:
<value>. Once active,
change them using(left)
and(right) arrow keys.
In general thekey
increments and thekey
decrements a value.
Selections wrap-around if
you continue to press the
key beyond maximum or
minimum values. Moving
away from the value field
(using /keys) overwrites
the original value.
The button takes you to the main menu.
The button can be thought of as an undo function.
It takes you back one screen. Changes that were in
process prior to pressing the key are lost.
Home Menu
The Home (or Main) menu
displays after the power-
up process completes. It
contains information on the
battery status and six menu
choices.

CALIBRATION
Calibration establishes a relationship between the
workplane illuminance and the light level measured by
the sensor. This can be done Automatically or Manually.
Automatic Calibration
Automatic Calibration can be started by the
LMCT-100, or by pressing and holding the user
pushbutton located in the sensor head.
1. Complete all wiring and turn power on to the connected
room controller.
2. Press and hold the user button for at least 2 seconds
then release, or activate automatic calibration from the
LMCT-100.
3. Blue LED will start flashing once every 4 sec.
4. Daylighting controlled loads will automatically turn ON
for 2 minutes to allow controlled lamps to warm up and
reach a stable full output.
5. Remove any objects that may affect the LMLS-400 light
level reading (ladder or temporary objects).
6. Lights will cycle eight times for automatic setpoint
selection.
7. The photosensor is in Test Mode when the blue LED
starts flashing once per second. For the next 5 minutes
the sensor will be in Test Mode.
8. Verify the setpoints automatically selected by the photo
sensor with the LMCT-100. If the automatic selected
setpoints are not acceptable, proceed to manual
calibration.

switch and after hours
interaction.
Light Level
Present light level measured
at the LMLS-400.
Allow Override
Determines if overriding the
photosensor is permitted or
not.
Available choices: Yes or No.
Override Time
Override Time selects the

control has been disabled
due to an observed external
user or system action,
before automatic control
resumes.
Range: Infinity or 1 to 24 hours.
Hold Off
The Hold Off setting selects
the behavior of daylighting
loads when they are turned
ON, by a switch or occupancy
sensor.
IfHoldOff=<No>(default),
the loads can always be turned on to their previous level,
and then will begin to adjust based upon daylight.
IfHoldOff=<Yes>,thesensorwilllimittheloadstothe
level presently allowed by daylight contribution. This
means that the loads may not initially turn ON (if the
ambient light level is high - above the ON or Dimming
Setpoint), but will become active for daylighting control,
and will turn ON or dim up as daylight contribution
drops.”

• Usethepushbuttononthephotosensorface
to manually test load control (see SENSOR
PUSHBUTTONS on page 3). If the lights do not switch
on and off, check Zone Setup to rebind the loads.
If the lights do switch on and off, use the Zone Settings
screen to verify that the On and Off setpoints are
correct (if Switched / Bi-Level / Tri-Level) or Day and
Night setpoints are correct (if Dimmed). Place the
photosensor in Test Mode to quickly verify daylighting
operation; shine a flashlight into the sensor, or cover
the sensor, to simulate major light level changes.

• ThereisaninternalfailureintheLMLS-400sensor.
Try unplugging the sensor from the DLM network,
then plug it back in and wait for ten seconds. If the red
