LED 1 and 2
The relays on the transceiver have LED’s. On the 2-pole transceiver, these are marked Relay 1, (1), and Relay 2, (2). When the corresponding LED is on, the relay is energized and should be closed. When the corresponding LED is off, the relay is not energized and should be open.
LED 3
When set up as a transmitter, LED 3, (3), blinks OFF and ON in 4 second intervals with a percentage of ON time as based on the outdoor temperature. The graph below illustrates the percent of time the LED is ON at various temperatures.
The warmer the outside temperature, the longer the LED stays ON. At 65° F or warmer, the LED is ON solid.
When the operation mode is receiver, LED 3 indicates when the PLC signal reception is established from the transmitting device. It blinks OFF-and-ON slowly then increasingly faster until it is ON solid. ON solid indicates that PLC reception is “locked in”.
NOTE: It can take 2-3 minutes for PLC signal reception when using a “fast” channel and 7-10 minutes when using a “slow” channel.

LED 4
LED 4, (4), responds to the power company’s control signal.
-
OFF when receiving an off-peak signal
-
ON solid if an override switch is enabled
-
blinking OFF and ON according to the type of signal being received from the control device.
This graph illustrates the time, in seconds, the LED is OFF-and-ON during various types of signal periods.
NOTE: Power company peak signal overrides anticipated-peak and/or set back signals.
