Computer 8d-96 Manual — Circutor

Circutor Computer 8d-96 is a robust, digital power factor regulator designed for automatic reactive energy compensation in both single-phase and three-phase industrial installations. It is characterized by its compact 96x96 mm DIN size and true RMS measurement capabilities. Key Features Capacitor Step Control : Capable of controlling between 1 and 8 capacitor steps. Measurement Accuracy

| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | No power supply voltage. | Check auxiliary supply or measurement voltage inputs. | | Current reads 0 | CT circuit open or CT ratio incorrect. | Verify CT wiring and check programmed CT ratio in SETUP. | | Negative Power | CT polarity reversed. | Swap incoming CT wires on the terminal block or correct via software if supported. | | Incorrect PF | Voltage/Current phase mismatch. | Ensure L1 voltage is paired with L1 CT, etc. |

: Ensure the facility is drawing power, or verify the CT secondary wires on Terminals 5 and 6 are not open-circuited. 2. Over-compensation (Capacitive Reading) Cause : Target cos

The 8d-96 may have a manual refresh mode for harmonics. Pressing the UP and DOWN together might lock/unlock the harmonic display. The manual calls this "Peak Hold" or "Data Freeze."

Uses the FCP (Fast Computerized Program) system to minimize switching operations and maximize device lifespan. Display: Features an LED display for visualising and the status of connected capacitor stages. Installation and Wiring

: Microprocessor-controlled digital sampling of voltage and current. Technical Data Circutor Computer 8d-96 is a robust, digital power

C/K=Istep 1KCTC/K equals the fraction with numerator cap I sub step 1 end-sub and denominator cap K sub CT end-sub end-fraction For a 12.5 kvar step at 400V ( ) using a 400/5A CT (

Proper operation depends heavily on the correct physical relationship between the voltage measurement points and the current transformer (CT) placement. Measurement Accuracy | Symptom | Probable Cause |

Connect the common terminal to the control circuit of the capacitor contactors. Outputs 1 through 8 are assigned to the respective capacitor steps. 3. Programming and Setup

: Requires single-phase current measurement via a transformer and direct voltage connection to the other two phases.
