Power Input

Nominal supply voltage: 24 V DC

Allowable voltage fluctuation range: +20%, -15%

Typical operating current: 200 mA

Maximum power consumption: 3.5 W

Power connection adopts an 8-pin quick-disconnect (QD) connector.

Important Notice: Only 24 V DC power supply is applicable. AC power input will cause permanent irreversible damage to the device.

Output Interfaces

1. Relay Dry Contact Outputs

Flame Relay: SPST Normally Open (N.O.)

Operating logic: The contact closes when a valid flame is detected and opens under loss-of-flame or fault conditions.

Fault Relay: SPST Normally Closed (N.C.)

Operating logic: The contact opens in the event of internal scanner failure, power supply loss or hardware malfunction.

Contact Electrical Rating

Minimum switching load: 10 mA @ 5 V DC

Maximum switching load: 2 A @ 30 V DC; 2 A @ 230 V AC (resistive loads only)

2. Analog 4–20 mA Flame Strength Output

Optically isolated DC current signal referenced to the 24 V DC common potential.

Signal definition:

4 mA corresponds to the minimum identifiable flame threshold

20 mA corresponds to the maximum measured flame intensity

Maximum permissible loop load resistance: 750 Ω

Function: Transmits real-time flame intensity data to PLC or burner management systems.

Functional Notes (No External Control Inputs)

This flame scanner is not equipped with external discrete digital input terminals for remote reset or remote enable commands.

All configuration parameters are configured locally via front panel pushbuttons.

Built-in Internal Sensing Input (UV Sensor)

Integrated ultraviolet sensor with detection spectrum of 185–260 nm.

The internal sensing channel continuously captures flame flicker modulation signals; no external wiring is required for the optical sensor assembly.

1. Pre-commissioning Inspection & Mechanical Installation

Inspect the UV scanner lens for soot deposits, dust and contaminants. Wipe the optical viewing window with a lint-free cloth if contamination exists.

Secure the device onto mounting brackets and adjust its installation angle to guarantee an unobstructed line of sight toward the combustion flame zone.

Fit purge air piping where applicable to prevent continuous soot accumulation on the lens during long-duration operation.

Examine the 8-pin QD quick-disconnect connector; confirm no bent pins, cracks or risks of moisture ingress.

2. Wiring Verification & Power-on Check

Complete wiring in accordance with terminal definitions, covering the 24 V DC power supply, 4–20 mA analog signal loop, flame relay and fault relay circuits.

Double-check wiring polarity. Connection of an AC power supply is strictly prohibited, as it will cause permanent irreversible device damage.

Apply rated 24 V DC power and observe the status of the "Ready" LED. Allow roughly 10–20 seconds for internal self-diagnostic initialization.

Confirm no fault alarm LED activates upon power-up.

3. Optical Alignment & Signal Optimization (Aim Mode)

Maintain stable burner operation with a consistent target flame.

Press and hold the Target Flame Select button to activate aiming mode.

Gradually fine-tune the mounting angle of the scanner while monitoring the 4–20 mA output signal and flame strength LED indicators.

Adjust the orientation until the maximum stable flame signal (peak 4–20 mA reading) is achieved. Firmly tighten all mounting lock nuts to lock the position.

4. Target Flame Learning (Mandatory Procedure)

Keep the flame operating under steady normal combustion conditions.

Simultaneously press the Target Flame Select and Background Flame Select buttons to open the password entry interface.

Use UP/DOWN buttons to input the access code, then confirm by pressing both buttons again.

Press and hold the Target Flame Select button to launch the target flame learning sequence.

The Ready LED will flash throughout the learning process; release the button once the procedure finishes.

The scanner automatically records flame flicker spectrum, amplitude and threshold parameters for the target flame.

Note: Target flame learning must be completed prior to normal operational use.

5. Optional Background Flame Learning (For Complex Furnace Environments)

Carry out background flame learning if reflected radiation, residual furnace glow or interfering signals are present.

Re-enter programming mode after finishing target flame configuration.

Tap the Background Flame Select button to initiate background signal sampling.

The unit records non-target interference signals and automatically raises the flame detection threshold to avoid false flame detection.

Save all parameters by long-pressing the Background Flame Select button for 2 seconds.

6. FFRT (Flame Failure Response Time) Configuration

Access the parameter setting menu after flame learning.

Select the Flame Failure Response Time option via UP/DOWN navigation keys.

Adjust the response time within the adjustable range of 1 second to 4 seconds; the factory default setting is 1 second.

Configure a suitable delay compatible with the safety logic of the burner management system. Avoid setting an excessively long FFRT value.

Save configurations and exit the parameter menu.

7. Functional Simulation & Full Performance Test

Flame ON Test

Maintain burner firing status and verify operating conditions:

The flame relay contact closes; the 4–20 mA signal outputs a stable value within the 4–20 mA range; the HMI or PLC receives valid flame-on feedback signals.

Flame OFF Trip Test

Intentionally cut off fuel to extinguish the flame:

Verify the flame relay opens within the configured FFRT window; the 4–20 mA signal drops to the minimum 4 mA level; the burner management system receives loss-of-flame alerts and triggers safety interlock logic.

Restore fuel supply and re-ignite the flame, and confirm the scanner resumes normal flame detection automatically.

8. Interference & Stability Verification

Run the burner sequentially under low-fire, rated-load and high-fire operating modes.

Continuously monitor scanner output to ensure no intermittent false loss-of-flame alarms occur under variable load conditions.

Check for UV interference originating from adjacent lighting, plasma sources and other radiation equipment. Install shielding components if abnormal signal fluctuations appear.

9. Post-commissioning Lock & Document Recording

Exit programming mode once all parameters are validated.

Fit the protective cap over operation buttons to prevent unintended manual adjustment.

Document commissioning data including mounting angle, FFRT setting, steady-state 4–20 mA flame signal reading, commissioning date and all test results.

10. Safety Precautions

Do not start the learning sequence without a genuine combustion flame; incomplete flame sampling will lead to detection malfunctions.

Avoid frequent power cycling during parameter saving operations.

Regularly monitor purge air pressure to sustain lens cleanliness.

Replace the scanner unit promptly if fault LEDs remain illuminated after repeated power restarts.
