Load Control Arbitration
To take full advantage of automatic PnG configuration, review these simple rules about load
control arbitration.
After the room controllers are connected to the DLM Local Network and powered up they
automatically negotiate to determine which controller becomes the Master and the load numbers
for each relay on the DLM Local Network.
The Master is the controller with the most load relays and the highest serial number. The LMRC-211
and the LMRC-211-347 Room Controllers each have one load relays.
In a DLM local network with only LMRC-211 or LMRC-211-347 Room Controllers, the Room
Controller with the highest serial number is the Master, carrying Load 1. The next highest serial
number would have Load 2, and so forth.
Load Selection Procedure.
A configuration button (Config) allows access to our patented Push n' Learn™ technology to change binding relationships between sensors,
switches and loads.
Step 1 Enter Push n' Learn.
Press and hold the Config button (on any DLM device) for 3 seconds.
• The red LED on the Controller begins to blink. When you release the button, the red LEDs on other
communicating devices connected to the DLM Local Network begin to blink. They continue to blink until
you exit PnL mode.
• All loads in the room turn OFF immediately after entering PnL, then one load will turn ON. This is Load
#1, which is bound to switch button #1 and occupancy sensors as part of the Plug n' Go factory default
setting. All switch buttons and sensors that are bound to this load have their blue LED solid ON.
Step 2 Load selection.
Press and release the Config button to step through the loads connected to the DLM Local Network. As each load turns ON note the
devices (switch buttons and sensors) that are showing a bright solid blue LED. These devices are currently bound to the load that is ON.
The blue LED on the room controller or plug load controller connected to the load is also lit.
• To unbind a switch or dimmer button from a load, press the switch button while its blue LED is ON bright. The blue LED goes dim
to indicate the button no longer controls the load that is currently ON.
• To unbind an occupancy sensor, press the up () or down () adjustment button while its blue LED is ON. The blue LED turns
OFF to indicate the sensor no longer controls the load that is currently ON.
Pressing the switch or up () or down () button again while the load is ON rebinds the load to the button or sensor and the blue LED
illuminates brightly.
Step 3 Exit Push n' Learn.
Press and hold the Config button until the red LED turns OFF, approximately 3 seconds.
LEDs on a switch or sensor
don't light.
The wrong lights and plug
loads are controlled.
LEDs turn ON and OFF but
load doesn't switch.
Lamps do not dim, or
lamps drop out at low dim
levels.

TROUBLESHOOTING
1. Check to see that the the device is connected to the DLM Local Network.
2. Check for 24VDC input to the device: Plug in a different DLM device at the device location. If the
device does not power up, 24VDC is not present.
• Check the high voltage connections to the room controller and/or plug load controller(s).
• If high voltage connections are good and high voltage is present, recheck DLM Local Network
connections between the device and the room controller(s).
1. Configure the switch buttons and sensors to control the desired loads using the Push n' Learn
adjustment procedure.
1. Make sure the DLM local network is not in PnL.
2. Check load connections to room controllers and/or plug load controllers.
1. Make sure a 0-10V dimming ballast and rapid start sockets are installed per the ballast
manufacturer's recommendation. Shunted sockets are typically not acceptable.
2. Check wiring per ballast manufacturer's instructions.
