Technical performance and structural features: LME ... for single-stage or two-stage gas burners in the start-up and during intermittent operation of monitoring and control. Flame monitoring via ion bar or flame detector QRA and auxiliary equipment AGQ3 or blue flame detectors QRC. LME, LGB, LMG, dimensions and installation specifications are identical, according to the time and mode of operation, each corresponding model common use. The controller is a microprocessor-based design, with a communication function for a single-stage or two-stage gas burner control for small and medium intermittent operation. 1. comply with EN298 standard burner control. 2. Strong exhaust burner conform EN676 standards. 3. undervoltage detection. 4. Start with the air pressure switch to monitor air pressure and runtime. 5. convenient remote reset. 6. The multiple color display error state and operation state information. 7. limited number of repeated cycles. 8. precise control order is due to the use of digital signal processing. To be shut down after the first 9.4 hours of continuous operation. UV flame detector auxiliary components: AGQ3.1A27AGQ3.2A27 Installation Notes: 1. The controller unit and other cables must be installed separately from the high-voltage ignition cables. 2. Do not confuse the hot and neutral lines. 3. Install switches, fuses, earthing, etc., must comply with local rules. 4. It is important to confirm the amount of current terminal can not exceed the maximum allowed. . 5. Do not burn the main power supply to the controller output terminals. . 6. From the mains power source with an all-polar switch will isolate the burner control, leaving at least 3mm contact gap. 7. Use a metric screw and washer relax under the protection of the chassis ground sleeve. . 8. In the case of not using the fan, a AGK25 must be connected to the terminal on the controller 3, otherwise the burner can not be reliably started. 9. For safety reasons, the neutral wire is connected to the bottom of the insert block neutral distributor or terminal 2. As shown below, the burning of components (fan, ignition transformer and valves) Figure 7435a14 listed, you must be connected to the neutral conductor. . 10. The connection between the two neutral wires and terminals at the bottom of the control unit is pre-wired.
