1. Pressure sensor: boiler pressure is controlled by pressure sensor. When the pressure is lower than the set value of the pressure controller, the output signal of the pressure controller is connected; when the pressure is higher than the set value, the signal is disconnected; after the signal is disconnected, it is connected again when the pressure drops to the set value of return difference. (Note: the product has been set before delivery. If you need to change it, please contact our after-sales service engineer.)
2. Pressure controller: the overpressure protection of the boiler is output by the detection signal of the pressure controller. When the operating pressure of the boiler exceeds the rated working pressure, the pressure controller outputs the signal to stop the operation of the boiler.
3. Water level signal: the controller uses the water level electrode to measure the water level. When using, pay attention to the insulation at both ends of the water level electrode, and do not get damp. When the resistance at both ends of the water level electrode is lower than 100k, the controller thinks that the water surface is higher than the electrode; when the resistance at both ends of the water level electrode rises above 500K, the controller thinks that the water surface is lower than the electrode.
4. Liquid level floating ball control (customized function, please specify when ordering): for the use of pure water or deionized water (the conductivity is very low, which causes the water level electrode to detect the water level failure, we use the floating ball water level monitoring. The boiler water level is controlled by triggering the float switch by the liquid level.)
5. Remote control: the remote control can realize the single machine operation of the equipment, or the host can give the switch start signal to realize the remote start of the equipment, and implement process monitoring and alarm output reminder during the operation process.
6. Alarm protection: after the controller is turned on, it will continuously detect the pressure sensor, water level electrode and its own circuit, and immediately alarm and shut down the boiler for protection in case of any fault. The controller automatically displays the fault point, and the buzzer in the machine sends out an alarm.
