It is normal and intentional that you cannot log in as an administrator with the GM/A in the supplied state, but only as a user at first and then as an administrator?
The double login (enabling of the administrator by a user) is absolutely necessary for reasons of compliance with EN 50131 and VdS 2252. The EN standard and the VdS directive both call for compliance with so-called access levels. There it is demanded that only the system engineer may change the system. The system operator must “activate” the system engineer (administrator) for this purpose, however.
Tip: The double login can be avoided for commissioning purposes by creating a new user and a new user group with administration rights.
