The Honeywell C7061 A/F is a dynamic self-checking flame detector designed to sense ultraviolet (UV) radiation produced by the combustion of various fuels, including gas and oil. This device is crucial for ensuring the integrity of both the amplifier and the flame detector through a closed-loop, self-checking circuit. In the event of an improper response or simulated flame loss, the system initiates a safety shutdown and/or alarm.
Two versions of the detector are available: the C7061A for standard applications and the C7061F for installations requiring explosion-proof packaging. The C7061F's housing conforms to EExd IIC T6 classification, making it suitable for hazardous environments. Both models are designed for use with either the R7061 Dynamic Self-Check Ultraviolet amplifier and R4348 Flame Switch, or the R7861A Dynamic Self-Check Ultraviolet amplifier and 7800 SERIES Burner Programmers.
The C7061 A/F detector utilizes an oscillating shutter mechanism that periodically interrupts the UV radiation reaching the UV sensor. When used with the R7861 amplifier and 7800 SERIES, the shutter operates at 12 times per minute, providing a continuous self-check of the UV sensor tube. With the R7061 amplifier and R4348 flame switch, the shutter frequency is 60 times per minute. This dynamic self-checking ensures that any malfunction in the flame detection system, including the amplifier circuitry, results in a safety shutdown.
The detector's UV sensing tube detects ultraviolet radiation emitted by combustion flames. This signal is then sent to the flame safeguard control's amplifier, which pulls in the flame relay to allow proper system operation. The detector's ability to "see" the flame is critical, and its placement should be as close to the flame as physical arrangement, temperature, and other restrictions permit.
