Status Light on newer style Power Injectors

Has anyone seen any official information to describe or explain the meaning of the LED on the newer style Power Injector?

In some cases we have seen it blinking.

AFAIK the led is merely just an indication of power. I’ve seen them flicker a few times as well, but it was because the outlets they were plugged into were bad.

we’ve seen them blink in a VERY steady patter when connected to a bad SM

so - this remains an unknown?

Solid = normal +24VDC operation
Flash = short or continuity between the + and -
