Fireye 85UVF1-1QD Integrated Flame Scanner

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The Fireye 85UVF1-1QD Phoenix Series Flame Scanner is an integrated, microprocessor-based combustion safeguard designed to detect ultraviolet emissions from gas, oil, or multi-fuel flames. By combining UV sensing electronics, signal processing, and onboard flame relay/analog outputs into a single NEMA 4X explosion-proof housing, it eliminates the need for an external flame amplifier module inside the main burner control panel.

Sourcing the 85UVF1-1QD as New Surplus is an essential risk-mitigation strategy for power plants, refineries, chemical facilities, and industrial boiler operations. A failing flame scanner halts burner operation instantly, leading to unprogrammed steam loss or total process shutdowns. Maintaining factory-fresh, unused spare units in plant inventory ensures immediate replacement without waiting on long manufacturer lead times or running the risk of installing unreliable, thermally degraded second-hand units.

Installation & Configuration Guide

1.Pre-Installation (Prep & Safety):LOTO, gas shutoff, and safety protocols.

Isolate main power to the burner control system and lock out fuel supply valves following strict plant lock-out/tag-out (LOTO) procedures. Ensure the burner sights are cool and clear of combustible gas mixtures before installation. Put on ESD wrist protection when handling quick-disconnect cable harnesses.

2.Removal:Disconnecting quick-disconnect cable and mounting adapter.

Unscrew the locking collar on the 12-pin quick-disconnect cable assembly and pull the cable straight out from the scanner housing. Unscrew the scanner from the 1-inch NPT sight pipe union adapter on the burner housing and set the old unit aside.

3.Installation (Clone & Seat):Physical alignment, sight pipe mounting, and cable seating.

Inspect the glass lens and threads on the new 85UVF1-1QD for cleanliness and structural integrity. Thread the scanner firmly onto the 1-inch NPT sight pipe swivel mount, aligning the optical line-of-sight directly with the primary combustion zone (intersection of fuel and air). Plug in the 12-pin quick-disconnect connector and hand-tighten the threaded locking ring to maintain the NEMA 4X environmental seal.

4.Power-On & Testing:24 VDC power check, signal verification, and gain setup.

Re-energize the 24 VDC control circuit and observe the onboard diagnostic LEDs. Light the burner pilot/main flame and measure the 4–20 mA analog output signal across the BMS terminals to confirm strong flame signal amplitude (typically >10 mA). Adjust internal gain/flicker settings if necessary using the Fireye software configuration tool or manual setup procedures to prevent background discrimination false triggers.

Firmware/Software Versions & Upgrade Notes

• Software Configuration: The 85UVF1-1QD supports communication with Fireye Wizard software via an RS-485 interface for remote monitoring, gain adjustment, and flame frequency tuning.
• Sight Pipe Purge Air: Ensure a continuous supply of clean, dry instrument air (3–5 SCFM) is piped to the sight pipe fitting to keep the scanner lens cool and free of soot accumulation.
• Wiring Caution: Never connect 120 VAC or 230 VAC line voltage directly to the 85UVF1-1QD terminals. This unit operates strictly on a 24 VDC class 2 power supply; overvoltage will destroy the internal microprocessor board.

Frequently Asked Questions (FAQ)

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

Why choose New Surplus over a refurbished Fireye flame scanner?

Flame scanners mounted on burner fronts are subjected to continuous ambient radiant heat, vibration, and thermal cycling. Refurbished or pulled units often contain aged UV photodiode sensors and dried-out electrolytic capacitors that lead to nuisance flame-outs, false trips, or unrepeatable 4–20 mA signals. Our New Surplus 85UVF1-1QD scanners offer factory-fresh optical sensors, clean internal circuitry, and uncompromised safety reliability.

How do you verify the condition of the 85UVF1-1QD scanner?

Our technical team performs thorough inbound quality inspections on every scanner. We verify pristine optics, untouched quick-disconnect pins, un-marred NPT threads, and confirm that the housing remains in clean, anti-static protective packaging.

What is the difference between 85UVF and 85IRF Fireye scanners?

The 85UVF series utilizes solid-state ultraviolet sensors optimized for gas and light oil flames where UV radiation is abundant. The 85IRF series uses infrared sensors suited for heavy oil, coal, or dirty combustion applications where UV light is blocked by particulate matter or moisture.

Can the 85UVF1-1QD be installed in hazardous locations?

Yes. The Phoenix 85UVF1-1QD features a heavy-duty cast aluminum enclosure rated for Class I, Division 2, Groups A, B, C, D hazardous locations, as well as ATEX/IECEx intrinsically safe environments when installed according to OEM control drawings.

What warranty is provided with this New Surplus Fireye unit?

We back this New Surplus Fireye 85UVF1-1QD flame scanner with a full 1-year replacement warranty. If any functional or electrical defect arises under standard operating conditions within 12 months, we replace the unit directly from our stock.
