DESCRIPTION
The LMPO-200 is a daylight sensor specifically designed to be used in conjunction with an LMIN-104 Digital Interface Module or LMIO-301 DLM Photocell Input Module. The LMIN-104/LMIO-301 converts the 10 VDC signal from the photocell sensor to a digital signal that is shared across the DLM Local Network. The signal is forwarded as a BACnet object via a DLM network bridge to the segment network for load control via a DLM segment manager or BACnet- compatible Building Automation System (BAS).
INSTALLATION
Install the sensor on the roof of the building facing north. The sensor housing is equipped with a ½” NPT nipple and will thread into any suitable watertight box or fitting. Orient the housing so that the hood is above the lens to provide shielding.
WIRING
Connect the sensor to the LMIN-104 or LMIO-301 as shown.
DLM SYSTEM CONNECTION 
MAINTENANCE
At least once every two months wipe the lens clean with a non-scratching clean cloth. Check the housing for damage, and be certain that no moisture has penetrated the sensor, as this will likely render it inoperable.
