 Trouble shooting:
-Look for the failing phase, which will be the phase that is not showing VE.Bus Error Code 1. And check the LEDs on that phase to find out what the reason was for the shut down.
+__ Diagnosing by LEDs__
+Look for the failing phase, which will be the phase that is not showing VE.Bus Error Code 1. And check the LEDs on that phase to find out what the reason was for the shut down; which is typically Overload, Low battery or Temperature. The other units will indicate a VE.Bus error, indicating that they miss one unit.
+Note that, due to the automatic restart, it is required to look at the LEDs while the issue is still present and the system is switched off.
+__Diagnosing on a GX Device__
+The GX Device will indicate the VE.Bus Error #1 as well as the alarm status for each of the phases:
+{{ :ve.bus:vebus_alarm_status.png?nolink |}}
+Note that, due to the automatic restart, it is required to look at the LEDs while the issue is still present and the system is switched off. Uploading the data to VRM will show a log; see GX manual, section VRM for details; both for systems with internet connection and systems without.
 __Diagnosing on VRM__
 First make sure that Automatic alarm monitoring is enabled; that is necessary to create the Overload and Temperature errors in the log. You will see Overload and Temperature alarms occurring at the same time as VE.Bus Error 1.
-Note for split- and three-phase systems: VRM, nor the GX device, will indicate on which phase the overload or the temperature alarm occured. To find out on which unit the error occurs, go to system after it has switched off. And look on the LEDs. The unit with the overload or temperature alarm, will have the corresponding alarm LED lit continuously. The other units will indicate a VE.Bus error, indicating that they miss one unit.
+Note for split- and three-phase systems: VRM as well as the GX device indicate on which phase there is an Overload, Low battery or Temperature alarm.
 __Recovery:__ auto-restart once the error is gone.
