3.1 Official Circutor Website

Go to -> www.circutor.com -> Support -> Technical Documentation -> Search "Computer 8d-96". Look for file names containing "M98118101". As of 2025, the manual is still available in English, Spanish, French, and Portuguese.

1.1 What Is the Circutor Computer 8d-96?

The Circutor Computer 8d-96 is a reactive energy regulator primarily used to control capacitor banks. Its main function is to measure the power factor (cos φ) of an electrical network and automatically connect or disconnect capacitor steps to maintain a target power factor—typically 0.98 inductive to 0.98 capacitive. The Ultimate Guide to the Circutor Computer 8d-96:

The “8d” in the name refers to 8 relay outputs for controlling up to 8 capacitor steps. The “96” denotes the standard 96mm x 96mm DIN-size front panel, a common form factor for panel-mounted industrial meters and controllers.

Section B: The Front Panel Interface

The manual dedicates pages to the 7-segment display and four keys: PROG, ENTER, UP, DOWN. Manualslib

• Default screen: Rolls through V, A, kW, kVAR, cos φ.
• Programming mode: Hold PROG for 3 seconds. You will see a code (P.000). The default password is often 0000 or 1000.
• CT/PT Ratio setup: Page 16-20 (typical). Here you enter your external transformer ratios. If you have 1000:5 CTs, you must program this number. If you get incorrect power readings, your CT ratio is wrong—this is the first place to check.

Q5: What is the lifespan of the 8d-96?

The manual states 10+ years typical, but electrolytic capacitors in the power supply may fail after 8–12 years. Periodic inspection recommended.

Step 6: Set P15 (C/k ratio). This is critical.

C/k = (CT primary current) / (Capacitor step kvar × 1000 / (√3 × line voltage))

Example: CT = 1000:5A, 6 steps of 25 kvar each@400V → C/k ≈ 0.40. The manual provides a lookup table to avoid math errors.

Q4: My manual is in Spanish. Is English available?

Yes. Search for “Computer 8d-96 User Manual English” and look for “Idioma: EN” on the cover page.
