Fireye 85UVF1-1QD Flame Monitor

1. Power Parameters: Adopts 120V AC power supply, with a power frequency of 50/60Hz. The operating current is small, approximately 0.2A, with low power consumption. It can adapt to the power supply environment of industrial sites and operate stably.

2. Detection Range: Specifically detects within the ultraviolet spectrum range, with high sensitivity to ultraviolet radiation generated during flame combustion, enabling effective identification of the presence of flames. It is insensitive to ultraviolet radiation from non-flame light sources such as sunlight and incandescent lamps, having strong anti-interference ability.

3. Response Time: The response speed is fast. The time from detecting flame abnormality to outputting a signal does not exceed 1 second, enabling quick response and timely triggering of safety protection mechanisms.

4. Output Signal: Equipped with 1 SPDT (Single Pole Double Throw) relay output, with a contact capacity of 10A @ 250V AC. It can directly control external equipment such as fuel valves and alarm devices, with stable and reliable output signals.

5. Environmental Adaptability: The operating temperature range is -40℃ to 85℃, allowing normal operation in extreme high and low temperature environments; the relative humidity is 0% - 95% (non-condensing), adaptable to humid environments. The shell protection level reaches NEMA 4X (IP66), with good dustproof and waterproof performance, suitable for installation in outdoor environments or industrial sites with much dust and water vapor.

6. Installation Parameters: The installation method is threaded installation, with an interface size of 1/2 inch NPT, facilitating connection with observation holes of various combustion equipment. The monitoring distance can be adjusted according to actual needs, and good detection results can usually be maintained within the range of 0.3 meters to 3 meters.

1. High-Precision Flame Detection: Adopts advanced ultraviolet sensors and signal processing technology, capable of accurately identifying the ultraviolet characteristics of flames. Even in complex industrial environments, it can accurately distinguish between flame and non-flame light sources, avoiding false alarms and missed alarms, with high detection accuracy.

2. Wide Range of Environmental Adaptation: Has excellent environmental adaptability, able to work stably in environments with extreme temperatures, humidity, much dust, and water vapor, not overly affected by harsh environmental factors, ensuring the continuity and reliability of flame monitoring.

3. Rapid Fault Response: When detecting abnormal situations such as flame extinction and insufficient flame intensity, it can quickly output signals through the relay, promptly notifying the control system to take corresponding safety measures, such as cutting off fuel supply and activating alarm devices, minimizing safety risks.

4. Self-Inspection Function: Built-in perfect self-inspection mechanism, which can conduct real-time self-inspection on key components such as sensors and circuits. If a fault is found in itself, it will output a fault signal, facilitating maintenance personnel to detect and handle it in time, ensuring the normal operation of the monitor.

5. Easy Integration: Compact structural design, simple installation method, and standard output signals, enabling convenient integration with various industrial control systems, PLCs (Programmable Logic Controllers), etc., without complex adaptation adjustments, reducing the difficulty of system integration.

1. No Output Signal

• Causes of Fault: Power supply not connected or abnormal power supply voltage; loose wiring, open circuit, or poor contact; internal circuit faults of the monitor, such as relay damage.

• Solutions: Check the power connection to ensure normal power supply and that the voltage meets the 120V AC requirement; recheck the wiring, fasten loose connectors, and repair open circuit parts; if there is an internal circuit fault, contact professional maintenance personnel for repair or replace the monitor.

2. False Alarm of Flame Abnormality

• Causes of Fault: The monitor lens is blocked by dust and oil, resulting in decreased detection sensitivity; there are strong ultraviolet interference sources nearby, such as arc welding and ultraviolet germicidal lamps; sensor aging, leading to performance degradation.

• Solutions: Clean the monitor lens to remove obstructions; keep away from strong ultraviolet interference sources or take shielding measures to reduce interference; if the sensor is aging, replace the sensor or the entire monitor.

3. Flame Extinction Not Detected

• Causes of Fault: Improper installation position of the monitor, not aligned with the flame; damaged ultraviolet sensor, unable to detect flame ultraviolet rays; detection sensitivity set too low.

• Solutions: Adjust the installation position to ensure the monitor can clearly observe the flame; check the sensor, replace it if damaged; appropriately increase the detection sensitivity according to the actual situation (adjustment needs to refer to the product manual).

4. Equipment Unable to Start

• Causes of Fault: Power supply faults, such as fuse blown; incorrect power wiring; damaged internal power module of the monitor.

• Solutions: Check the power circuit and replace the blown fuse; recheck the wiring and correct wiring errors; if the power module is damaged, contact the manufacturer for repair or replace the equipment.
