Preparation for automatic commissioning

Required parameters during the auto commissioning process are:
- Type of connection. The type of connection defines the way of CT connections for
RVT. There are total eight different types of connection for CTs, which depends
on how many current measurements and how these CTs are connected. Detailed
description on the type of connections can be found in paragraph 4.3.1.2.
- CT Scaling: Current Transformer ratio (for instance a 250A / 5A CT has a CT
scaling of 50). More info can be found in paragraph 4.3.1.2.
- Target cos j (in paragraph 4.3.1.3.)

Automatic commissioning

- if you have a short-circuit on the CT's secondary winding do not forget to open it
after having connected the current input of the PF Controller
- if a transformer is used for the voltage measurement, the Vscaling value needs to
be changed accordingly (see paragraph 4.3.1.)
Notes: when the icon
the display, this means that the RVT is locked. The set Mode access is denied and
commissioning cannot be performed until the RVT is unlocked (see description in
paragraph 4.3.1.1.)
