Lamtec 659R60 F200K 2 IR-1 Flame Detector

LAMTEC TYPE 659R60 | 0200000 F200K 2 IR-1 FLAME DETECTOR

The Lamtec Type 659R60 (Model: F200K 2 IR-1) is a state of the art high integrity compact flame scanner for continuous monitoring of single and multi-burner combustion systems. This device integrates the optical flame sensor and the evaluation/switching amplifier in a single, sturdy cylindrical container, delivering fail-safe performance for industrial boilers, power plants and marine engineering. It distinguishes background radiation from active combustion dynamics using an Infrared (IR-1) spectral arrangement, giving dependable trip warnings in case of a flame-out.

• Testing Devices: Lamtec FFP30 Flame Scanner Testing Device.
• Cabling Options: LiYcY standard control cables (-40 °C to +80 °C) or high-temperature silicone-insulated cabling with optional stainless steel protective armor tubes.
• Burner Systems: Compatible with industrial burners utilizing gas, light oil, heavy fuel oil (HFO), or mixed-fuel setups.

Applications

• Marine steam boiler combustion monitoring
• Large-scale thermal power station utility boilers
• Industrial water-tube and fire-tube boilers
• Chemical plant processing furnaces and waste incinerators
• Multi-burner systems requiring independent flame discrimination

Expert’s Guide

1. Optical Alignment is Critical: When mounting the 659R60 on marine boiler windboxes, ensure the sighting tube is purge-aired correctly using clean instrument air. Even minor soot or oil mist buildup on the front lens quartz glass will attenuate the IR spectrum and trigger false low-signal trips.
2. Frequency Tuning: Take advantage of the internal digital frequency evaluation stages. If erratic boiler flicker causes unstable relay behavior at high firing rates, adjust the frequency filter switch to block background mechanical modulation frequencies.
3. Loop Testing: Utilize the 4–20 mA diagnostic port during initial burner commissioning. A stable baseline reading above 10 mA during high-fire operation confirms proper optical alignment, whereas erratic fluctuations indicate unstable flame root attachment.

Frequently Asked Questions

What is the primary function of the Lamtec 659R60 F200K flame detector?

The unit continuously monitors burner combustion via an infrared sensor and cuts off fuel supply lines instantly through a safe relay output if a flame failure occurs.

Can this scanner withstand high ambient temperatures near industrial burners?

Yes, the housing is designed to handle high radiant heat environments, and when paired with proper cooling/purge air adapters and correct cabling, it operates reliably up to demanding thermal thresholds.

How do I verify if the scanner is correctly powered and reading a flame?

You can verify operation via the onboard status LEDs or by connecting a multimeter to the 4–20 mA output terminals to check real-time signal intensity.
