Description
The Fireye EUVS4 is a self-check UV amplifier module used with the Fireye Flame-Monitor system to enable self-checking ultraviolet flame scanning. It installs into the amplifier guide channels of the EB700 chassis after scanner selection, processing the ultraviolet signal into a supervised flame signal suitable for burners that fire continuously.
Paired with the 45UV5-1007, 45UV5-1008, and 45UV5-1009 self-check scanners, the module exercises the safety checking circuit during operation and produces a 560 VAC measurement across terminals S1-S2 with no flame present. It carries UL Listed, Factory Mutual, and Industrial Risk Insurers approvals for dependable continuous-duty monitoring.
Frequently Asked Questions
What is the primary difference between the EUVS4 and the standard EUV1 amplifier?
The EUVS4 is a self-checking amplifier, whereas the EUV1 is a non-self-checking (standard) ultraviolet amplifier. The EUVS4 is specifically designed for continuous operation (burners that remain on for 24 hours or more). It works in tandem with self-checking scanners to periodically "shutter" or block the UV sensor for a fraction of a second to ensure the system hasn't failed in a "flame-on" state. Standard amplifiers like the EUV1 should only be used on burners that cycle at least once every 24 hours.
Which flame scanners are compatible with the EUVS4 module?
The EUVS4 is designed to be used exclusively with Fireye self-checking ultraviolet scanners. Specifically:
45UV5 Series: Models 45UV5-1005, -1007, -1008, and -1009.
55UV5 Series: Models 55UV5-1007 and -1009.
Can I hot-swap the EUVS4 module while the Flame-Monitor system is powered?
No. You must always remove power from the wiring base before replacing or installing the flame amplifier module. The EUVS4 is installed in the third set of guide channels in the EB700 Flame-Monitor chassis. Forcing the module into the chassis or plugging it in while energized can damage the gold-plated edge connectors or the internal microprocessor.
What does it mean if my system locks out with a "Flame Failure" during continuous firing?
When using the EUVS4, a "Flame Failure" during a long run-cycle often indicates a Self-Check Failure. This happens if the amplifier fails to detect the simulated "darkness" when the scanner’s shutter closes. Common causes include:
- A faulty shutter mechanism in the 45UV5 scanner.
- Worn-out UV tubes that have become "leaky" (detecting background radiation or failing to clear during the check).
- Electrical noise interference on the scanner wiring (ensure S1 and S2 leads are run in a separate grounded conduit).
