UNIT DESCRIPTION
The LMIO-301 photocell input module is an accessory for a
networked Digital Lighting Management (DLM) installation
that allows an LMSM segment manager to read ambient
light levels for use in controlling exterior lighting or interior
lighting installed in brightly day-lit spaces such as atriums.
The LMIO-301 works in conjunction with either the LMPO-
200 exterior or LMPS-6000 skylight low voltage photocell
heads.
OPERATION
The LMIO-301 operates on Class 2 power supplied to a DLM
local network by one or more room controllers or an LILM
panel. It transmits light levels over the segment network
as read from one of the remote analog LMPO or LMPS
photocell sensors. The LMIO-301 converts the analog signal
from the photocell sensor to a digital signal that is shared
across the network. The segment manager controls the
lighting based on user-defined setpoints and time delay
settings.
APPLICATION
The LMIO-301 photocell input module is an ideal solution
for any application where exterior lighting needs to be
controlled based on actual ambient exterior light levels
such as parking, site and landscape lighting. Applications
with large expanses of skylight, clearstory or atrium glazing
can also benefit from controlling lighting based on ambient
light entering the building through the glazing.
When controlling outdoor lighting, the LMPO-200 photocell
head mounts on the roof of the building facing North. The
LMPO-200 photocell head is waterproof and has a built in
hood to shield the lens from direct sunlight.
The LMPS-6000 photocell head is designed for indoor
applications with direct exposure to extremely high light
levels as would be present adjacent to the glass in an
atrium, skylight or clearstory.
For full operational details and more features
of the Digital Lighting Management (DLM
System), see the DLM System Installation Guide
available at www.wattstopper.com

TERMINAL CONNECTIONS
1-10V Photocells: connect the photocell
output to terminal 10 (Input 2).
0-5V Photocells: connect the photocell
output to terminal 9 (Input 1)
MOUNTING AND WIRING
Installation shall be in accordance with all applicable
regulations, wiring practices, and codes.
To be connected to a Class 2 power source only. • Class 2
Device Wiring Only – Do Not Reclassify and Install as Class
1, 3 or Power and Lighting Wiring. • Wire connections shall
be rated suitable for the wire size (lead and building wiring)
employed.
The LMIO-301 is UL2043 Plenum rated.
All connections to the LMIO-301 are Class 2 low voltage.
If code requires that the LMIO-301 be mounted in an
enclosure, it can be mounted inside a 4” x 4” junction box,
inside a 21/8” deep (or deeper) 1-gang wall box, in a 3” or 4”
octagonal box, or on a din rail inside a building automation
panel.
Attach the LMRJ Cable
The DLM local network uses free topology low voltage
wiring. The LMIO-301 can connect anywhere on the DLM
local network.

ADJUSTMENTS
The LMIO-301 is equipped with a Configuration button. This
button is provided for convenience in initiating DLM local
network PnL mode; there are no binding functions needed
for the LMIO-301.
The inputs may be configured using its DIP switches for
different light input levels on each of the photocell input
terminals. Input 1 is claibrated for connection of 0-5VDC
photocells. Input 2 is calibrated for 1-10VDC from photocells
such as WattStopper LMPO and LMPS models.

If you connect, reconnect or
change the photocell while
the LMIO-301 is powered,
toggle DIP switch #8 to On
then Off. This initializes
sampling on the input and
communication with the DLM
Local Network.
LED INDICATORS
The LEDs signify when input 1 or input 2 is activated, when
the 24VDC output is overloaded and when PnL is active.
Blue LEDs
Input 1: Blinks when Data from Input 1 transmits to the
DLM Local Network.
Input 2: Blinks when Data from Input 2 transmits to the
DLM Local Network.
24V Overload: Blinks (1x/sec) when terminal 5 (24VDC)
output exceeds 5mA and the LMIO-301 shuts off the
output. LED goes OFF when the overcurrent condition
is removed.
Red LED
Config: intermittent flashes indicate DLM system local
network activity. Blinking at regular intervals of 2x/
second indicates the local network is in PnL.
TROUBLESHOOTING
The blue LED for 24V Overload is blinking (1x/sec).
This means that the 24VDC output from terminal 5
exceeded 5mA. The output has been shut OFF. The LED
turns OFF when the overcurrent condition is removed.
• Make sure only one photocell is connected to the
LMIO-301.
• Check wiring to terminal 5.
Do not connect
more than one
photocell to the
LMIO-301.
