65UV5 Simplicity Integrated Flame Scanner with Internal Flame Relay
DESCRIPTION
The Fireye 65UV5 flame scanner is a microprocessor based flame scanner utilizing an ultraviolet tube-type sensor and an electro-mechanical self-checking shutter mechanism. The Fireye 65UV5 flame scanner incorporates an internal flame relay with a fixed ON/OFF threshold thereby eliminating the need for an external flame amplifier. The 65UV5 scanner is available with a one-second or four second flame failure response time (FFRT) depending on the model selected. The “E” versions are one second FFRT, the non-”E”versions are four seconds FFRT. The Fireye 65UV5-1004QD, -1004EQD flame scanner provides an analog 4 to 20 mA output referenced to flame signal strength. The Fireye 65UV5 flame scanner is powered from a 24 Vdc power source provided externally and includes an integral 8 pin quick disconnect connector. A color-coded internal LED indicates flame status and alarm condition. This can be viewed through a viewing port on the rear cover. The 65UV5 housing has a NEMA 4X / IP66 rating. The unit is suitable for use in Class 1, Div. 2 hazardous environment groups A, B, C & D or Ex II3 G/D Ex nA IIC T4A. 65UV5 CEX models are wired directly via a terminal rail located within the CEX housing. Suitable glands must be used to terminate the cable at the housing. Note: The 65UV5-1000, -1000E scanners became obsolete in 2008, and were replaced by the enhanced capability of the 65UV5-1004 and -1004E scanners. The 65UV5-1004QD and -1004EQD models with electrical quick-disconnect have replaced the original models equipped with ten feet of captive cable.
