Description of the LED function
1.
Chasing light (over all LEDs): The bootloader is active. No normal functions
are possible.
2.
All LEDs flash shortly every 6 s: An internal data error was detected and cor-
rected automatically! The module still works regularly. To acknowledge the error
the module has to be cycle powered.
Both yellow LEDs flash oppositely every 1 s: The nonvolatile stored parameters
are inconsistent! To acknowledge the error the data have to be saved with the SAVE
command or the corresponding button in the WPC. If the function of the module has
changed via the FUNCTION parameter, all parameters are deleted purposely and set
to default values. In this case the LEDs indicate no error, but a desired state. To
acknowledge please save.
