2.1.2 LED indication at Service Calls
If service calls occur, all four LEDs blink on and off to notice it. And then when press the [Go] button, distinguish a fault from the specific combination of ON/OFF and status color of the LED.
When entering this state, instruct the end user to turn off the power switch, wait a few seconds and the same service call appears, see the reference page to take the corrective action.
