Alternatively, I can generate a for a technical manual (safety, installation, operation, troubleshooting) that you could adapt once you confirm the exact Circutor model.
The device functions as an intelligent controller that monitors the network's

Websites like manualslib.com , manualmachine.com , or electricalpartmanuals.com often host scanned copies of the original 8D96 manual. Search for "Circutor Computer 8D96 wiring diagram manual full". Verify the PDF has at least 40-50 pages (the quick guide is only 2 pages).
setting. Check if a capacitor contactor is mechanically stuck in the closed position. Low Compensation
According to the manual and expert guides, the following are the key programmable parameters:
Connect to the secondary loop of the Current Transformer (CT). The CT must be placed on the remaining phase (e.g., L1) that is not supplying the voltage measurement inputs. This establishes the standard 90-degree phase shift required for precise calculation.
: The transformation ratio of your current transformer (e.g., 500/5 = 100).
Connect each terminal to the respective contactor coil of the capacitor steps.
You must define the sizes of your capacitor steps relative to the first step. For example, a 1:1:1:1 program means all steps are the same size. A 1:2:2:2 program means the first step is a base value, and subsequent steps are twice as large. 4. Connection / Reconnection Time
Accurately reads both inductive and capacitive power factors (consumer or generator states).
The Circutor Computer 8d96 is a digital power factor regulator designed for automatic capacitor bank switching. It measures the reactive power of an electrical installation and connects or disconnects capacitor steps to optimize efficiency and eliminate penalties on electricity bills.
The is part of the "Computer-8d" series of power factor regulators, which were historically produced in two sizes: the 96mm x 96mm Computer-8d-96 and the larger Computer-8d-144 for DIN 43 700 panel mounting. Manufactured by the Spanish company Circutor S.A., this regulator is designed for automatic power factor correction in electrical installations. It continuously monitors the grid's power factor (cos φ) and automatically connects or disconnects capacitor banks as needed.
