Circutor Computer 8d96 Manual [work] Full Jun 2026
: Never disconnect the CT secondary without first short-circuiting it to avoid dangerous overvoltages. Protection
: Visual indicators marking whether the system is experiencing capacitive or inductive load conditions. 2. Mechanical and Electrical Installation
Define how many of the 8 available relays are actually connected to capacitors. 4. Operational Modes
Clear visualization of electrical parameters. 8 Relay Outputs: Controls up to 8 capacitor banks. Compact Size: 96x96 mm DIN format for easy panel mounting.
The Computer 8d96 is equipped with built-in alarms to protect your capacitor bank and warn you of grid irregularities. Common alarms include:
Define your desired power factor. The default industry target is usually set between 0.95 and 0.98 Inductive. Avoid programming a value of 1.00 or a capacitive target, as this can induce resonance or overvoltage conditions in your electrical network. 3. C/K Factor (Response Sensitivity) circutor computer 8d96 manual full
The Computer 8d-96 is a member of Circutor’s Computer-8d series. These are that digitally read the power system's cosine phi (cos φ) — the power factor — and automatically connect or disconnect capacitors to improve it.
The Computer 8d96 is a reactive power regulator designed to measure the cos

What is your (e.g., 400/5, 1000/5)?
Check for welded contactor contacts keeping capacitors stuck on. Lower target power factor. Maintenance and Operational Safety : Never disconnect the CT secondary without first
calculations, resulting in the regulator cycling indefinitely or failing to engage capacitor steps. The current flowing through the CT must point from the source (Grid) to the load (Installation). Terminal Block Connections
Power supply and voltage measurement inputs.
C/K=Ic (Smallest Step)K (CT Ratio)C/K equals the fraction with numerator cap I sub c (Smallest Step) and denominator cap K (CT Ratio) end-fraction Example: If your smallest step is 10 kvar at 400V ( ), and your CT is 500/5 ( 4. Delay Times (Connection and Reconnection)
Units must be properly grounded before power is applied.
: While the standard 8d is suitable for most stable industrial loads, the 8df model is specifically designed for environments with fast load fluctuations, offering a significantly lower response time of 0.1 to 10 seconds . Mechanical and Electrical Installation Define how many of
Indicates the system cannot achieve the target power factor, even with all capacitor steps connected. Fix: You may need to add more physical kVAR capacity to your bank.

This dictates when the regulator activates or deactivates capacitor banks. Locate the target parameter (often displayed as cos ).
: Audit the contactors physically to ensure they open cleanly when their control relays drop voltage.
