In its standard configuration, when the mini receiver is first energized, a red light on the circuit board will begin to flash slowly. This indicates the receiver is waiting for a signal. When valid bits of information are received, the light will begin flashing more rapidly. There may be occurrences where the light will switch from a fast flash back to a slow flash. After several minutes, the mini receiver will synchronize with the transmitter, and the light will illuminate continuously to indicate complete information is being received. This red light monitors power line carrier (PLC) communication as follows:
Slow Flash: Mini receiver is waiting for PLC communication.
Fast Flash: Mini receiver is receiving partial PLC communication.
Continuous Illumination: Mini receiver is receiving complete PLC information
There is also an amber indicator light on the circuit board. This light is used to indicate whether the relays are open or closed. It will also indicate if a peak override has been initiated. The amber light monitors the status of the relays as follows:
No Illumination: relay(s) open
Flashing: override enabled
Continuous Illumination: relay(s) closed
These lights can only be seen when the mini receiver enclosure is open. They are not accessible to the user in normal operation.
