We recommend executing the automatic initialisation (AI) for commissioning. This identifies the
connection of the controller (phase between voltage and current) and automatically determines the
correct phase correction angle (SETUP/206).
The CX plus performs a connection type identification of the measuring voltage (L-L / L-N) depending
on the set nominal voltage. With the aid of these data, the control starts automatically.
The nominal voltage and, if necessary, the current transformer factor must also be entered for other
mains voltages.
!
CAUTION
If the connection of measuring voltage and current results in a phase not equal to 0° (connection
voltage = L-N) or not equal to 90° (connection voltage = L-L), execute the automatic initialisation
(AI) first or manually set the phase correction angle (SETUP/206) correctly. Otherwise, the
calculation of the powers, of the COS-PHI and of the stage sizes is incorrect and the control does
not work correctly or not at all.
The CX plus can be adjusted to the system conditions and be optimised in the setup menu at any time.
NOTE: The menus 200 to 700 are hidden in the quick START menu. In order to show these menus,
change to the EXPERT setup.
