Detection Sequence
Once a compliant load is attached to the output RJ45 connector,
the green “CONNECT” LED will illuminate.
Should the load be non‐compliant, then the LEDs will blink a
code signifying the cause for non‐detection.
Detection Failure Codes
1. Incorrect resistive signature – The green “CONNECT” and
red “FAULT” LEDs will blink 3 times.
2. Incorrect capacitive signature – The green “ON” LED will
blink 3 times.
3. Incorrect Voffset – The green “CONNECT” and green “ON”
LEDs will blink 3 times.
4. Unstable current measurement – The green “ON” LED will
blink 3 times.
5. Low voltage sensed during detection (overload) – The red
“FAULT” LED will blink 3 times.
After the LEDs blink 3 times the BL‐69551ENT will continue to
try to detect a valid load. Therefore, until the correct load is
applied, the LEDs will continue to blink. If there is an open
circuit connected to the output RJ45, then the LEDs will not blink
but the BL‐69551ENT will continue to try to detect a valid load.
Fault Sequence
Should there be a fault such as an overload or short circuit, then
the red “FAULT” LED will illuminate. The red “FAULT” LED
will illuminate for 2 seconds and then go off as the power supply
tries to re‐detect a valid load. If there is a problem in detecting,
the LED will indicate what is wrong with the load as per the
codes in the section above.
