| | Likely Cause | Remedial Action | | :--- | :--- | :--- | | Controller does not switch on | No or incorrect power supply; Blown fuse. | Check incoming AC supply voltage at the controller terminals; check and replace the protective fuse if necessary. | | Capacitors do not switch in | CT polarity reversed; Target PF already met; Load current too low. | Verify CT wiring and direction. Check if the actual PF is close to the target. Check if system load is above the minimum switching threshold. | | Power factor is over-corrected (leading) | Target PF set too low (e.g., 0.80); Incorrect CT ratio causing wrong measurement. | Increase the target PF (e.g., to 0.98 inductive). Verify and correct the CT ratio setting in the controller menu. | | Capacitor steps switch on/off rapidly (hunting) | Switching delays are too short; Load current is very close to the switching threshold. | Increase the correction and discharge delay times. Slightly adjust the switching sensitivity in the controller settings. | | Display shows "UC" or "OC" error | Under-capacitor current (UC): Capacitor not connected or step contactor failed. Over-capacitor current (OC): Capacitor failure or harmonic resonance. | Check wiring for that specific capacitor step. Inspect the capacitor's fuse or circuit breaker. For "OC", perform a harmonic analysis of the installation. | | Display shows "VA" | Measurement voltage is absent on at least one phase. | Check the measuring voltage fuses and wiring for a loose or broken connection. | | Display shows "OD" | Outputs are disabled. | Check the status of any active protection triggers, such as over-temperature or over-voltage. Check the "Auto/Manual" mode selector. |
Go to the step configuration menu (Step 1 through Step 16) and manually enter the kVAr value or ratio value (e.g., 1:1:1 or 1:2:4) for each connected stage. Set unused steps to "0" or "Off". 5.

Automatically senses the reactive power output of connected capacitor steps during commissioning. 2. Installation and Technical Wiring
Power factor correction involves adding capacitors or inductors to the system to compensate for reactive power, thereby improving the power factor.
The BR 5016 can automatically identify step sizes, making commissioning faster. C. Display and Parameters Real-time Monitoring: Displays The Epcos BR5016 stands out from entry-level controllers
Self-optimized switching minimizes switching operations to prolong capacitor life.
Wire the step outputs (Relay 1 to Relay 16) to the coils of the capacitor contactors. Use a common auxiliary supply phase to feed the common relay terminal.
Integrated interfaces (such as RS485 or Modbus) depending on the exact sub-model suffix. Intelligent Switching Programs | Check incoming AC supply voltage at the
Always isolate the switchgear panel from the main power source before touching the rear terminals of the BR5016.
: Allows for separate power factor targets for utility power and DG (Diesel Generator) mode.
