Proof UV flame detectors

FZWJ-306B-proof UV flame detectors for gas, flame monitor fuel industrial burners, which monitors only the ultraviolet light sensitive to light and high temperatures in the furnace no response, immunity to interference. First, the features: automatic ignition control ignition device, the ignition and automatically open the fuel valve. Does not ignite within the set time, the controller automatically turns off the fuel valve and the police, such as the successful ignition of the fuel is maintained normal supply. Second, the main technical parameters: 1, Power: 200V ± 10% 50 / 60Hz 2, flame detection: Uv sensor 3, the detection response time: ≤0.2 seconds 4, spectral response range: 190 / 280mm 5, the sensor and the controller connection : ≤20 m 6, detect objects: gas, oil three, four external connection diagram, terminals as shown in Figure The following figure (internal) 1: Power FireWire 2: neutral wire 2,3,4: UV probe 5,6 : Contact Firearms AC220V 6,7: fuel solenoid valve connected to AC220V 8,9: passive normally open contact, when a flame flip. 9.10: passive normally closed contact, when a flame flip. Note: If sending DCS control leads from the terminal, when a fire through 8,9, 9,10 pass without fire. V. Installation 1. Open the top cover when connecting the power cable, control cable connection according to the figure in the corresponding terminals. (The power cable is connected) 2, followed by the UV probe connected to the connection terminals 2,3,4, and fixed tight (Received). 3, probe mounting. FZWJ-306B UV flame detector is a non-contact type flame detectors. When a user installation, set the probe aligned flame. Highest temperature probe used is 80 ℃, when the user uses the burner or other hot equipment, the probe must be ventilated before the monitoring channel cooling, the product with mounting brackets, mounting screw probe is M20 × 1.5. According to relevant regulations, monitoring sensitive distance of 0.8 meters, (in detection channel for the next Φ18 case), but the distance will be monitored with increasing radiation intensity and flame monitoring channels increased, but the maximum distance can not be more than two meters. 2. In order to improve monitoring of the sensitivity of commissioning, the sensor cables should not be mixed with other power line or signal line. FZWJ-306B-proof UV flame detector at the factory has been debugged, in general, the installation can be used. If the probe is too far away from the monitor, the distributed capacitance caused by the wiring is too large, in the absence of flame Show fire, open the template clockwise slowly adjust the template matching middle potentiometer until the green light is off, the relay releases So far, the module debugging good, good debugging, the cover module cover. Please note that debugging Do not overshoot, overshoot impact monitoring sensitivity. Sixth, troubleshooting 1, the burner without fire, but has shown a fire monitor, which is distributed capacitance increases moisture monitor the line after a disturbance, open explosion-proof box, then open the module clockwise slowly adjust the potentiometer, until the green light is off, the relay released. 2, the burner fire, and monitors showed no fire, there may be two reasons, first, the probe lens is covered with dust, please clean the probe quartz lens, and second impedance matching potentiometer overshoot, turn counterclockwise slowly template adjust the potentiometer until the green indicator light, relay so far. 3, if you do not accidentally break the probe lens in the installation or use, do not use ordinary glass instead, because ordinary glass can not be produced by a fire of ultraviolet rays through.
