6.1 General notes on commissioning
Compensation unit with controller
The controller is congured as a compensation system component (see connection dia-
gram) by default. The following settings need to be congured or checked:
Target cos phi according to electricity supplier specications.
Primary and secondary current in the main circuit according to the transformer tted.
If required, set the measuring voltage transformer data.
If no stage powers have been programmed, the controller will switch to the Commis-
sioning menu after initialization. Next, stage power programming can be performed in
the settings menu, or using the learning process.
NOTE
You can start the learning process from the "Learning mode activate" submenu in the
Commissioning menu, using the Enter/Input buttons.
If the "Learning mode" window is not displayed, please check the following:
is Menu on set for "Learning mode" in the "Extras" menu?
The settings are saved on an EEPROM so that they are not lost in the event of a power
failure.
Switch on a sucient number of inductive consumers (e.g. motors) before switching
the compensation system on. A transformer current of at least 15 mA needs to be ow-
ing in the secondary circuit for the controller to be activated. Below this limit, the error
message "No transformer current" will be displayed.
Check the transformer connection (is the transformer ratio too high?).
If all connection conditions are OK, the instantaneous power factor cos phi should be
displayed after initialization, e.g. Normally, when no capacitors are connected, cos phi
lies in the range of 0.6 to 0.9 inductive, (e.g. cos phi 0.80 ind).
