corresponding LED will indicate the error. The significance of the LEDs is described
on the bottom label of the unit.
When the unit is running on accumulator power the LED indications will switch to
blinking to consume less power. See the tables below for all supported indications.
Note that the individual visual error indications can be disabled by configuration.
Furthermore, all visual error indications can be disabled with a specific configuration
