Do you have a question about the WS D-71272 and is the answer not in the manual?

The Burner Control CBR is a microprocessor-controlled flame relay designed for the safe and reliable operation of industrial burners. It offers a comprehensive set of features for monitoring, control, and safety, making it suitable for various thermal processing applications.

Function Description:

The CBR acts as the central control unit for a burner, managing ignition, flame supervision, and various safety-relevant functions. It supports both standard flame mode and FLOX® mode, which is a specialized combustion process. The device continuously monitors critical parameters such as temperature, air pressure, and gas supply to ensure safe operation. In case of any deviation or fault, the CBR initiates a safety shut-down and displays a corresponding fault code for diagnostics. It also includes features for manual operation, allowing for controlled start-up and shut-down procedures, as well as maintenance tasks. The CBR can be integrated into larger control systems via Profibus, enabling remote monitoring and control.

Usage Features:

Display: The CBR features a 7-segment display for showing operating status, fault codes, and parameter values. Three LEDs (green, yellow, red) indicate the most important operating states.
Operating Modes: Supports automatic operation, manual air purge, manual heating, and manual FLOX® mode.
Parameter Configuration: Various parameters can be configured to adapt the CBR to specific burner types and applications. This includes delay times for ignition, pre-purge, post-combustion, and minimum ON/OFF times for flame and FLOX® modes.
Password Protection: Access to device configuration levels is protected by dedicated passwords to prevent unauthorized changes.
Profibus Integration: Allows for seamless integration into a Profibus DP system, enabling remote monitoring, control, and diagnostics. The CBR supports up to 126 devices on a single Profibus segment.
Fault Diagnostics: The CBR provides detailed fault codes displayed on the 7-segment display, categorized by status, burner, control, and internal faults. Each fault code is accompanied by a description of the fault/cause and recommended check/resolution steps.
Manual Operation: Specific manual modes are available for air purge, heating, and FLOX® operation, allowing for controlled start-up and testing.
Safety Features: Includes safety shut-down mechanisms for gas supply interruption, combustion air supply interruption, UV sensor removal, and pressure switch issues, particularly relevant for FLOX® mode.

Maintenance Features:

Ground Connection Test: Essential for safety, the ground connection must be tested regularly.
Safety Shut-down Tests: Regular validation of safety shut-down functions in both flame and FLOX® modes is required. This involves simulating fault conditions (e.g., interrupting gas/air supply, removing UV sensor) to ensure the CBR responds correctly.
Temperature Measurement Validation: For FLOX® mode, regular validation of temperature measurements and associated fault shut-off/alarms is crucial. This involves comparative measurements using a dual thermocouple and checking the CBR's information display.
Reset Functionality: The CBR has a reset button to clear faults. However, frequent resets (more than 5 within a 15-minute interval) indicate a persistent issue that requires investigation.
Error Codes: The detailed fault codes facilitate troubleshooting and maintenance by pinpointing the exact cause of a malfunction.
Component Replacement: The fuse is replaceable, and other components can be serviced by qualified personnel.
Documentation: The manual provides comprehensive information for troubleshooting, parameter configuration, and maintenance procedures.
WS Service Department: In case of persistent issues or unsuccessful reset attempts, contacting the WS Service Department is recommended.
