Fireye 85UVF1-1CEX Commissioning Steps

Perform lockout and tagout procedures prior to all commissioning work. Verify mechanical installation of the flame scanner, ensure the optical axis is accurately aimed at the primary combustion flame root of the burner with a clear and unobstructed optical path. Check instrument cooling air supply to guarantee adequate and stable airflow for scanner heat dissipation and quartz lens contamination prevention. Inspect all wiring for power supply, flame relay contacts, fault relay contacts and optional 4-20mA analog output, and fully fasten all explosion-proof cable glands to meet site explosion-proof requirements.

Energize the flame scanner and observe front-panel LED indicators. Wait for the device to complete power-on self-diagnosis and confirm no internal fault codes are displayed. If any fault alarm occurs, cut off the power supply, troubleshoot hardware defects and wiring abnormalities, and resume commissioning only after faults are eliminated.

Start the burner and maintain stable combustion under normal load conditions. Fine-tune the installation angle of the scanner, monitor the flame intensity LED and 4-20mA analog output signal in real time, and optimize the aiming position to ensure the flame signal amplitude stays within the standard and stable operating range.

Enter the configuration password by simultaneously pressing the Target Flame Select and Background Flame Select buttons, and confirm access to the system configuration menu via the corresponding password LED indicator. Set the Flame Failure Response Time (FFRT) in accordance with burner safety specifications, and save all parameters to the device’s non-volatile memory.

Complete target flame learning under stable actual combustion conditions. Press the Target Flame Select button to trigger the automatic flame learning routine. The scanner collects real flame spectral characteristics and amplitude data, and automatically calibrates the internal flame ON/OFF threshold values within the valid two-minute learning window.

Perform background flame learning if the furnace exists thermal background radiation or interference from adjacent burners. Under the no-flame furnace state, activate the background learning function to enable the scanner to effectively distinguish valid target flames from background interference, ensuring accurate flame identification. Save all settings and exit the configuration menu after calibration completion.

Conduct flame loss simulation testing. Cut off the burner fuel supply to trigger flame extinction, and verify device response performance. Confirm the flame relay de-energizes and the fault relay acts accurately within the preset FFRT time, with fault signals correctly transmitted to the BMS burner management system. Reignite the burner and confirm the scanner resumes normal flame detection status.

Check real-time operating parameters after commissioning. Verify that the 4-20mA analog output is linearly consistent with actual flame intensity, and check the device event log for abnormal trips or warning records. Confirm the interlock logic between the flame scanner and upper BMS system fully complies with safety design standards.

Perform repeated start-stop tests and variable load tests. Operate the burner under low-fire, high-fire and fluctuating load conditions to verify stable and reliable flame detection performance, without false flame signals or erroneous flame failure tripping.

Record all final configuration parameters after successful commissioning. Keep the scanner quartz lens clean at all times and ensure continuous and stable cooling air supply during long-term operation. Regularly perform device function verification using a professional UV test lamp for daily maintenance.

Fireye 85UVF1-1CEX

Input:

Power input: Rated for 24VDC power supply with a typical operating current of 200mA; requires continuous clean and dry purge air to cool the lens and prevent dust contamination.

Optical input: Detects ultraviolet flame radiation within the 295–340nm wavelength range through a quartz lens, capturing effective optical signals from burner combustion flames.

Local operation input: Equipped with two onboard physical buttons, supporting target flame learning, background flame learning and system parameter configuration.

External signal input: No reserved digital or analog signal interfaces for external process signal acquisition.

Output:

Relay contact output: Integrated SPST flame relay dry contact closes when valid flame is detected; independent SPST fault relay dry contact triggers under hardware failure or power loss conditions to realize safe interlock with BMS burner management system.

Analog output: Isolated 4–20mA DC analog signal output, linearly corresponding to real-time flame intensity, with a maximum load resistance of 750Ω for remote flame data transmission.

Visual indication output: Multi-functional status LEDs intuitively display flame existence, device fault status and configuration operating mode for on-site inspection.

Data storage output: Built-in non-volatile memory automatically saves calibrated flame threshold parameters and device fault event records.
