Product Description for Fireye 65UV5-1004E

Description: The Fireye 65UV5-1004E is an advanced ultraviolet (UV) integrated flame scanner, designed for high-performance combustion control and safety systems. This microprocessor-based device is an upgrade from previous models and is engineered to detect the presence or absence of a flame by sensing its UV emissions. It incorporates the sensor, processor, flame relay, and an analog output into a single, compact unit, providing a fast and reliable solution for industrial burners.

Application Scenarios: In a multi-burner environment, such as a large-scale industrial heating furnace, the rapid and reliable detection of a flame failure is critical for safety. A factory with an older burner management system was experiencing issues with flame-out incidents that were not detected quickly enough, leading to the risk of dangerous fuel accumulation. By retrofitting their system with the Fireye 65UV5-1004E scanners, the plant achieved a new level of safety. The “E” designation signifies a one-second Flame Failure Response Time (FFRT), a significant improvement over the four-second response time of earlier models. This allowed the system to shut off the fuel supply almost instantly upon a flame failure, mitigating the risk of explosions and protecting the facility’s assets and personnel.

Main Parameters Value/Description Product Model: 65UV5-1004E Manufacturer: FIREYE Product Category: UV Integrated Flame Scanner Sensor Type: Ultraviolet (UV) tube-type sensor, optimized for UV emissions from fossil fuel flames. Input Power: 24 VDC, a standard low-voltage supply for industrial controls. Flame Failure Response Time (FFRT): 1 second, providing rapid and safe response to flame-out. Output Signals:

• Internal Flame Relay: SPDT (1 N.O., 1 N.C.) with fixed ON/OFF threshold.
• Internal Fault Relay: SPST (1 N.O.).
• Analog Output: 4-20 mA DC current, referenced to flame signal strength. Self-Checking Mechanism: Electromechanical shutter for continuous sensor verification. Mounting: 1″ BSP female pipe mount, with a 3/4″ BSP female cooling air connection. Environmental Rating: NEMA 4X / IP66, for protection against dust, water, and corrosion. Hazardous Classification: Ex II 3 G/D Ex nA IIC T4A, suitable for use in certain hazardous locations.

Technical Principles and Innovative Values:

• Innovation Point 1: Rapid Flame Failure Response Time (FFRT): The “E” in the model number denotes a one-second FFRT, a key innovation for high-risk applications. This is a crucial safety enhancement that allows the system to react much faster to a flame-out condition, reducing the time for unburned fuel to accumulate in the combustion chamber. This rapid response time is critical for meeting stringent safety standards in modern industrial environments.
• Innovation Point 2: Integrated Analog Output for Diagnostic Insight: Unlike previous models, the 65UV5-1004E includes a 4-20 mA analog output. This innovation provides a continuous signal proportional to the flame’s intensity. This is a powerful diagnostic tool, allowing operators to monitor the health of the flame, identify a deteriorating burner condition (e.g., a dirty fuel nozzle), and perform predictive maintenance before a complete flame failure occurs.
• Innovation Point 3: Enhanced Self-Checking and Diagnostics: The 65UV5-1004E features an improved electromechanical self-checking shutter. This mechanism periodically blocks the sensor’s view of the flame, allowing the internal microprocessor to verify the entire signal chain. The unit also includes internal LED indicators for both flame status and fault conditions, providing local, at-a-glance diagnostics that simplify troubleshooting and reduce maintenance time.

Application Cases and Industry Value:

In a petroleum refinery, a critical crude oil heater required a high degree of flame safety and reliability. The refinery’s existing flame scanners lacked an analog output, making it impossible to remotely monitor flame signal strength. This meant that a weak or flickering flame could go unnoticed until a trip occurred, causing an unscheduled shutdown. By installing the FIREYE 65UV5-1004E scanners, the refinery gained valuable insight. The 4-20 mA output was integrated into their Distributed Control System (DCS), allowing operators to remotely trend flame signal strength over time. When one scanner’s signal began to slowly degrade, the team was able to schedule a burner inspection during a planned downtime, where they found and replaced a partially clogged fuel nozzle. This proactive maintenance, enabled by the 65UV5-1004E, prevented a costly trip and demonstrated its value in moving from a reactive to a predictive maintenance strategy.

Related Product Combination Solutions:

The FIREYE 65UV5-1004E is an integral part of a comprehensive burner management system and works in conjunction with:

• FIREYE Burner Controls: The 65UV5-1004E‘s flame relay and fault relay outputs are wired to the burner control (e.g., Fireye’s Nexus or E-Series), which manages the ignition and fuel valves.
• Programmable Logic Controllers (PLCs): The 4-20 mA analog output can be wired to a PLC’s analog input module, allowing for advanced monitoring, data logging, and integration into a plant-wide SCADA system.
• Control Room Indicators: The analog output can be used to drive a dedicated panel meter or display in a control room, providing a continuous, real-time indication of flame signal strength to operators.
• Fuel Valves and Actuators: The burner control, in response to the 65UV5-1004E‘s flame status signal, will operate safety shutoff valves and fuel control valves.
• Cabling and Connectors: The 65UV5-1004E uses a specific 8-pin quick disconnect connector, and compatible cables are essential for a reliable electrical connection in a hazardous environment.

Installation, Maintenance, and Full-Cycle Support:

The FIREYE 65UV5-1004E is designed for secure, professional installation on a sight pipe using its 1″ BSP thread. Its rugged, IP66-rated housing is built to withstand harsh industrial environments. Due to its self-checking shutter, routine maintenance on the scanner itself is minimal, primarily involving a visual inspection of the lens for cleanliness and ensuring proper cooling air flow.

The on-board LED and the analog output provide clear diagnostic information, allowing technicians to quickly identify a failed unit. While the 65UV5-1004E is a robust and long-lasting product, it is a legacy model. We provide comprehensive support, including access to a network for sourcing reliable, tested, and often new-old-stock or refurbished units, as well as expert technical assistance for installation, configuration, and troubleshooting to ensure your burner systems remain safe and reliable.
