The Westfalia Separator AG C7-623 control unit is an advanced electronic system designed for the automatic ejection control and condition monitoring of mineral oil separators. This unit is primarily intended for use with OSA, OSB, and OSC series separators, ensuring efficient and safe operation in various industrial applications.

Function Description

The C7-623 control unit serves as the central brain for managing the separation process. Its core function is to trigger total ejections of the centrifuge bowl at preset intervals, with or without prior product displacement. This precise control is crucial for maintaining high clarifying efficiency and minimizing desludging losses, especially when the separable solids content in the product fluctuates.

For OSC separators, the unit offers flexible ejection modes, including partial ejections, total ejections, and preselectable partial ejections followed by a total ejection. This adaptability allows for optimization based on specific process requirements.

A key feature of the C7-623, particularly when integrated with UNITROL systems, is its comprehensive monitoring capabilities. It incorporates two basic monitoring systems: the Water Content Monitoring System (WMS) and the Sludge Space Monitoring System (SMS). These systems continuously assess critical parameters, providing real-time data to ensure optimal performance and prevent potential issues.

The unit also supports series operation for two-stage HFO (Heavy Fuel Oil) treatment, demonstrating its versatility in complex separation processes. Software assignment to specific separator types is performed at the factory, often requiring a password for configuration, which ensures tailored functionality and security.

Usage Features

The C7-623 control unit is designed for user-friendly interaction, providing clear and concise information about the separator's operational status and any malfunctions. The illuminated four-line LC display presents relevant process data, making it easy for operators to monitor the system at a glance.

The control system extends beyond the main unit, encompassing all complete line fittings with electrical components that are controlled or monitored by the C7-623. This integrated approach ensures seamless operation and comprehensive oversight of the entire separation process.

Standard components controlled or monitored by the unit include:

• Dirty oil connection: Manages the inflow of the product to be separated.
• Water connection: Controls the supply of water for various process steps.
• Operating water connection: Specifically manages water used for operating the separator.

For UNITROL centrifuges, additional components are integrated:

• Circuit and water discharge valve: Regulates the flow of water within the system and its discharge.
• Water sensor: Monitors water levels or presence, crucial for process control.
• Pressure switch for the bypass line (in SMS function): Detects pressure changes in the bypass line, contributing to sludge space monitoring.

Optional extras enhance the unit's functionality and adaptability:

• Multi-purpose thermometer PT 100: Provides minimum/maximum temperature monitoring in the dirty oil, safeguarding against thermal issues.
• Level switch for monitoring water discharge: Ensures efficient and controlled water discharge.
• Process-dependent control of an external feed pump: Allows the unit to manage an external pump based on process needs.
• Level switch for monitoring the sludge tank: Prevents overfilling or underfilling of the sludge tank.
• Minimum and maximum level switch for controlling a sludge pump: Automates the operation of a sludge pump based on tank levels.
• Klaxon for audible alarm: Provides an audible alert in case of critical events or malfunctions.

The standard C7-623 unit is configured for single operation of purifiers or clarifiers. However, for two-stage HFO operation, series operating mode can be pre-selected after entering a password, requiring appropriate cabling of MPI (Multi Point Interface) interfaces.

Maintenance Features

The C7-623 control unit is designed with maintenance in mind, providing features that facilitate troubleshooting and upkeep. The clear display of operating and malfunction conditions, along with relevant process data, aids in quickly identifying issues.

The instruction manual provides detailed information on special functions and error messages, enabling maintenance personnel to diagnose and resolve problems efficiently. The modular design of the control system, with its integrated components, simplifies the process of identifying and replacing faulty parts.

The unit's ability to monitor various parameters, such as water content, sludge space, and temperatures, allows for proactive maintenance. By detecting deviations from normal operating conditions, potential failures can be anticipated and addressed before they lead to significant downtime.

The inclusion of optional features like the klaxon for audible alarms further supports maintenance by immediately alerting personnel to critical events, ensuring a rapid response. The overall design emphasizes reliability and ease of service, contributing to the longevity and consistent performance of the separation system.
