What is the status of the four small LEDs supposed to be on Pinsound Plus?

Question

Hi

I have a insound plus installed in a getaway. There are some LEDs for the voltages. Three are on, on the left it seems like there should be another on, but it isnt on (the on for GND).

Is there a fourth LED or not? Do I have a problem?

Please print a manual that explains these things. The installation sheet available is really not sufficient.

Answer 1

They are 3 (three) LED for the differents voltages rails.

Obviously 0V/GND is the ground, so no voltage difference here... The TP (test point) is used for manual voltage measurement.

Theses LED are used for advanced diagnosis, as installation is plug an play.

so this means that 3 LED on means that all is OK. Thank you :)
