Can control the ignition device to automatically ignite, and automatically open the fuel valve at the same time. If the ignition does not ignite within the set time (6 seconds), the controller automatically closes the fuel valve; if the ignition is successful, the fuel valve is kept open and the fuel is normally supplied. When the flame is monitored, if a flame is detected, the fire indicator light is on, keep the fuel valve open, and the fuel is normally supplied; when no flame is detected, the fire indicator light is off and the controller automatically closes the fuel valve.

RXFZJ-102 explosion-proof ultraviolet flame detector is a non-contact flame detector. Please point the probe at the flame when installing. 80℃，用户在燃烧器或其他高温设备上使用时，探头前的监测通道必须通风冷却，探头的安装螺纹为M20×1.5。 The maximum temperature used by the probe is 80 ° C. When the user uses it on a burner or other high-temperature equipment, the monitoring channel in front of the probe must be ventilated and cooled, and the installation thread of the probe is M20 × 1.5.
According to relevant regulations, the monitoring sensitive distance is 0.8 meters (in the case of a detection channel of Φ18), but the monitoring distance will increase with the increase of the flame radiation intensity and the monitoring channel, but the maximum distance generally does not exceed 6 meters.
To improve monitoring sensitivity, the sensor cable should not be mixed with other power or signal lines.
防爆紫外线火焰检测器在出厂时已调试好，一般情况下安装即可使用。 RXFZJ-102 explosion - proof ultraviolet flame detector has been debugged at the factory, and it can be used under normal circumstances. If the probe is too far away from the monitor, and the distributed capacitance caused by the wiring is too large, a fire is displayed without a flame. Please open the template and slowly adjust the matching potentiometer in the middle of the template counterclockwise until the relay is released. The module is debugged well. After the commissioning is completed, close the module cover. Please pay attention not to overshoot when debugging, overshoot affects the monitoring sensitivity.
1. The burner has no fire, but the monitoring shows fire. This is the interference caused by the distributed capacitance gradually increasing after the monitoring line is damp. Please turn on the module and slowly adjust the potentiometer counterclockwise until the fire indicator (green) goes out. The relay Until release.
2. The burner has fire, but the monitor shows no fire. There may be two reasons. One is that the probe lens is covered by dust. Please clean the quartz lens of the probe. The other is the impedance matching potentiometer overshoot. Please open the module slowly clockwise. Adjust the potentiometer until the ignition indicator (green) lights up and the relay closes.
3. If the lens of the probe is accidentally broken during installation or use, do not replace it with ordinary glass sheets, because ordinary glass sheets cannot transmit ultraviolet rays generated by flames.
Note: In any case, customers are not recommended to adjust the sensitivity of the product by themselves. If adjustment is required, please contact our technicians for guidance.
