LEGRAND Wattstopper Mode D'emploi page 7

Photocell Mode 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.

PHOTOCELL MODE
You must select "Photocell" in the Operating Mode drop-down in
LMCS in order to put the LMIN-104 into Photocell Mode.
Once in that mode, you should choose the Footcandle Range
for the photocell in LMCS. Once set there are two additional
parameters.
• Minimum Time to Update – The minimum period of time
before the LMIN-104 sends the current light level to the bridge.
A smaller number will give you more accurate readings, but will
increase the amount of messages sent on the DLM network.
• Minimum Change of Value to Update – The minimum change
of light level (in foot candles) before the LMIN-104 sends the
current light level to the bridge. A smaller number will give
you more accurate readings, but will increase the amount of
messages sent on the DLM network.
The Blue LED for Input 1 will blink when input data from the
photocell is transmitted on the DLM network.
Photocell Mode
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 LMIN-104.
• Check wiring to terminal 5.
