Reactive Factor Controller CX plus

SETUP (setup menu)
100 Quick START setup
Contains all the important settings for commissioning from the setup menus 200 to 400. This menu is
always visible. No further settings are necessary for the commissioning of the control in case of a
connection to a 400 V mains and in case of a connection of measuring voltage and current, where a
phase of 0° (connection voltage = L-N) or 90° (connection voltage = L-L) results.
NOTE:
At first, however, the current transformer factor must be set in order to correctly calculate and
display the current, the powers and the step sizes.
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 step 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.
