The Epcos Power Factor Controller BR 5016 Go to product viewer dialog for this item.
415 V AC (L-L) with a range of +20% to -30% at 50Hz. Capacity: 16-step control for 3-phase capacitors.
| | 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. |
Periodically check control and power terminal screws for tightness, as thermal cycling can loosen connections.
However, if you’ve just inherited an older system or are installing a replacement unit, you might find yourself searching for the instruction manual to decipher the wiring diagrams or parameter settings.
The BR 5016 can automatically identify step sizes, making commissioning faster. C. Display and Parameters Real-time Monitoring: Displays
