The regulator installed in your Powerlogic PFC Capacitor Bank pre-configured with your equipment, following settings have to be defined:
-
Target cos φ setting
-
Current transformer ratio value (allows to display the measured value correctly)
Important
-
If supplied by a summing CT (installation with several CTs), the sum of the ratios of the different CTs must be taken into consideration.
-
For an installation equipped with a generator set, the capacitor bank must be taken out of circuit, by breaking the supply to the controller, before switching to the generator set.
Simple Commissioning of PowerLogic PFC Controller
Before configuring the controller, make sure that the jumper on KL terminals is removed.
Go to SETUP 100:
-
Setup CT ratio (Ct), cos φ (CP1).
-
If the controller display is showing PFC OFF, set the PFC parameter to ON, before launching Ai.
-
Launch Automatic Initialization (Ai) by pressing Ai from OFF to ON.
The Ai automatically detects the capacitor steps connected and checks if the phase connection (angle between voltage and CT position) is correct. The Ai sequence switches the steps on and off several times. It will take several minutes to complete this process, and later the relay will stabilize.
During this sequence, the controller will display Ai.
Minimum Requirements to Launch an Ai
Following are the minimum requirements to launch an Ai:
-
Voltage must be within tolerance
-
CT must be connected
-
Capacitor protection must be closed
-
Input current not too low
For a Successful Ai Step Detection
-
Current loading shall be significant
-
Load variation shall not be significant
Successful Ai Sequence Information
-
If phase wiring is swapped (incorrectly wired), the controller automatically corrects the phase angle internally and moves to normal mode. Auto is displayed.
-
Final check of step detection:
-
Go to and check if the status of all steps are correct as per the PFC bank configuration (FIX OFF= Step not detected. AUTO= Step detected).
-
If necessary, change the OUT status to expected value.
-
Unsuccessful Ai Sequence [“Abrt” (abort) error]
If unsuccessful, run the Ai again. If the Ai aborts again, the phase connection (angle between voltage and CT position) cannot be detected. The control will move to PFC off mode and phase connection must be set manually. See PowerLogic™ VL series PF Correction Controller User Manual.
