Description
The Bollfilter BK2200 Main PCB Module (Part Number: 60580018) is the central control logic unit for the Boll & Kirch automatic backflushing filter series. This module serves as the command center for the entire filtration process, monitoring differential pressure across the filter elements and automatically triggering the backflushing sequence when contamination reaches a preset threshold. It is a critical component for ensuring continuous fluid flow and protecting sensitive downstream equipment in maritime and industrial applications.
Technical Parameters
- Model: BK2200 Main Control Module
- Part Number: 60580018
- Component Type: Central Processing PCB
- System Compatibility: Boll & Kirch BK2200 Automatic Filter Series
- Input Power: Typically 24 VDC or 110-230 VAC (depending on the specific filter configuration)
- Origin: Germany
Application Areas
- Marine Propulsion: Filtering lube oil and fuel oil for main and auxiliary engines.
- Cooling Systems: Managing sea water and fresh water filtration to prevent heat exchanger fouling.
- Industrial Process: Maintaining fluid cleanliness in heavy-duty hydraulic and lubrication systems.
Product Usage Instructions
- Safety: Always disconnect power to the filter unit before accessing the control cabinet.
- Installation: Ensure the PCB is firmly seated in the mounting rails. Verify that all terminal block connectors are securely latched to prevent intermittent signal loss due to vibration.
- Configuration: The module utilizes DIP switches or a keypad interface (depending on the specific version) to set pressure thresholds. Configure these according to your system’s required differential pressure setpoint (measured in bar).
- Diagnostic Status: Observe the status LEDs on the board. A steady signal usually confirms normal monitoring mode, while a flashing sequence indicates an active backflushing cycle or a system alarm (e.g., motor overload or high-pressure lockout).
Product Description
The 60580018 acts as the intelligent interface between the pressure sensors and the backflushing actuator. It continuously tracks the differential pressure (\Delta P) across the filter media. When the \Delta P exceeds the defined limit, the module initiates the cleaning sequence: it activates the gear motor to rotate the cleaning arm and opens the backflush valve to discharge contaminants. This autonomous operation is vital for preventing system downtime and manual maintenance interventions.
Protection & Environmental Parameters
- Enclosure: Designed for integration within the filter’s integrated control box (usually IP54 or higher).
- Conformal Coating: The board is protected with an industrial-grade coating to prevent oxidation and short-circuits caused by the humid and oily environments common in ship engine rooms.
- Operating Temperature: 0°C to +60°C.
- Humidity: 10% to 95% relative humidity, non-condensing.
Frequently Asked Questions
- How do I identify if the Main PCB is faulty? Common symptoms include the filter failing to trigger a backflush cycle even when the differential pressure is high, or “Motor Overload” alarms that persist after the filter has been mechanically inspected.
- Is the 60580018 field-repairable? Due to the complexity of the integrated circuits and the critical nature of the filtration system, component-level repair is not recommended. Replacement with a new, factory-programmed module is standard practice.
- Do I need to re-calibrate the system after replacing the board? Yes. After installing a new 60580018, ensure the differential pressure sensor input is calibrated correctly so the module triggers cleaning cycles at the appropriate contamination level.
- What precautions should I take against vibration? Ensure the control cabinet door is sealed and that internal cabinet mounting screws are tightened to damp the vibrations typical of large machinery installations.
