The terminal layout for current transformers (CTs) and voltage references is precise. Incorrect wiring can lead to the controller displaying negative power factor or failing to switch capacitors. The manual provides detailed pinouts for both the measurement inputs and the relay outputs.
Once you download the PDF, it spans approximately 40-60 pages. You do not need to read every page. Focus on these five critical sections. --- Epcos Power Factor Controller Br 5016 Manual Pdf
The manual describes three distinct modes accessible via the Mode button: The terminal layout for current transformers (CTs) and
The Epcos BR 5016 (now produced under the TDK brand) is a digital power factor controller. Its primary job is to monitor the reactive power in an electrical network and switch capacitor steps in or out to maintain a target power factor (usually close to 1.0). This is the section most users bookmark
While you wait for the PDF to download, here is a generic overview of the setup process:
This is the section most users bookmark. To enter programming mode, press the Prog button for 3 seconds. The manual lists the following parameters (abbreviated):
| Code | Parameter | Typical Setting | Explanation |
| :--- | :--- | :--- | :--- |
| C/F | Current transformer ratio | e.g., 2000/5 | Must match your physical CT. |
| U | Nominal voltage | 400V or 480V | System line-to-line voltage. |
| C-- | Target Cos φ | 0.92 to 0.95 | The manual warns: setting 1.00 may cause hunting. |
| t-- | Switching delay | 15 to 60 seconds | Time before controller reacts to changes. |
| P no | Number of steps | 1 to 16 | Set to the actual number of capacitor stages. |
| P5 | Sequence type | 1:1:1 or 1:2:4 | Linear or binary stepping. |
