There are 5 leds on the toppanel. The status of those leds depends on there blinking frequency and duty cycle.

explanation per led: [<frequency> <duty cycle>] The one in bold is the default value

powerled

main program

[1Hz 10%] led blinks short every second : main process is not yet started, if this stays for a long time there is something wrong to initialize.
[1Hz 50%] led blinks normal ones a second : main process is running and everything is ok, there is also communication
[4Hz 50%] led blinks normal but fast : main process is running and all ok, but there is no communication
[1Hz 90%] led is almost constant on but blinks off ones a second : addressmode

The status of the 3 voltage leds is the same but each for its own voltage channel

[1Hz 10%] led blinks short every second : There is commnication with the the processor who measures the voltage but the voltage level is to low
[1Hz 90%] led is almost constant on but blinks off ones a second : There is a voltage signal measured on the corresponding voltage channel and the voltage is higher than 50V
[4Hz 50%] led blinks normal but fast : There is a problem to communicate with the processor who measures the voltage.

The leds represent the address of the module in binary format see voltage 1-3 in bootloader mode for more info

[no 0%] led is off : bootloader is not yet started, if this happen for a long time there is something wrong to initialize.
[1Hz 50%] led blinks normal ones a second : bootloader is running and there is also communication
[4Hz 50%] led blinks normal but fast : bootloader is running but there is no communication yet

The leds represent the address of the module in binary format [V1 V2 V3]b ex. if V1 is off and V2 and V3 are on -> 011 = address E3

For all addresses above 7, module 8 operation is preformed.
