Quanta Flame Series 5002-01 Self Checking UV Scanner

The Quanta-Flame Series 5002 is intended for monitoring all gas, oil and coal-fired burners.  The control is the basis for industrial or commercial burner management systems using microprocessors, PLC or relay-based hardware. All essential circuits are supervised.

A Flame Status LED and Flame Relay LED provide useful diagnostic information on the front of the scanner.

Flame Relay LED: The Flame Relay LED (FRL) is a single color LED. When a flame of sufficient intensity is detected the 5002-01 control will activate the output signal. This output may be any one of the possible output forms described above. While the output is activated the FRL will illuminate. Should the flame signal fall below the minimum threshold, or should one of the internal circuits or sensing elements tests fail, the output will deactivate and the FRL will shut off.

Flame Status LED: The Flame Status LED (FSL) is a dual color LED that acts as a multi-functional indicator. When a flame is detected the FSL will illuminate with a red color. This light will vary in intensity proportional to the level of flame signal (flame strength) detected.  Every 10 seconds the self-checking mechanism will interrupt the light coming from the flame. This is done to verify that the UV sensing element is still functioning properly. When this check is being performed the FSL will momentarily turn to a yellow color (when flame present) or green color (when flame is not present). Should the UV sensing element fail to function, the scanner will lockout all the outputs to indicate the failure and the FSL will remain green without blinking for one minute. After one minute the control will automatically reset itself. The scanner’s microcomputer will then continue to check the sensing element every ten seconds. Should the sensing tube be in a permanent “runaway “condition then the scanner will immediately lockout again for another period of one minute.


The 5002-01 UV self-checking scanner is ideal for natural gas, landfill gas, refinery gas, and light oil fired burners. It interfaces with Preferred, Honeywell, Fireye, Siemens, Eclipse, and PCI flame safeguard microprocessors. The -C versions output a contact closure and a 4-20 mA signal to interface with PLC or DCS-based flame safeguard systems.
