User Manual of EM730 Series Inverter 1. After selecting the water supply macro, the status parameters that need to be paid attention to in water supply have been preset. They are: output frequency, setting Pressure, feedback pressure, output current, the shift key can cyclically switch the above state values. You can skip the set parameters by setting 0.00 through F12.33- F12.37 to reduce the length of the shift key switching cycle. The set pressure and feedback pressure units are bar, and the corresponding Hz+A lights are on at the same time. The set pressure Hz+A light flashes, and the feedback pressure Hz+A light is always on. 2.
After selecting the water supply macro, the rotary potentiometer becomes to adjust the given pressure. The setting is effective immediately. If you do not press the confirmation key, the power will not be saved. Press the confirmation key to save the set pressure value and update the F09.01 target pressure setting. The external LCD keyboard can adjust the given pressure through the up and down keys in the monitoring interface. After the given value is set, the power will be turned off by default to save the given value. 3.
After the rotary potentiometer changes the set pressure, in the running state, it will immediately switch to the output frequency display state if there is no operation for about 1.5 seconds. 4. Press and hold the confirmation key on the EM730 potentiometer for 3 seconds to lock the digital potentiometer's ability to adjust the given pressure. The keyboard displays Lock to prevent the set pressure from being changed by mistake. If the rotary potentiometer displays Lock, the potentiometer setting pressure has been locked. Press and hold the confirmation key for 3 seconds again to unlock the pressure setting of the digital potentiometer. The keyboard displays uLock.
The pump startup process is based on the acceleration time. Acceleration time 1 is used for acceleration at startup. F00.14 acceleration time 1 = 10s, F00.15 deceleration time 1 = 15s are preset at the factory, and P and I parameters are preset to accelerate the pump motor quickly. For faster acceleration, you can appropriately reduce acceleration time 1, but do not set acceleration time 1 too small. Sleep wake-up logic Sleep logic: When the feedback pressure is greater than the set pressure, the frequency starts to decrease.
When the output frequency is less than the sleep frequency (F09.45), then after the sleep delay time (F09.29, the constant pressure PID adjustment is performed throughout the process), the tube is sealed and the sleep state is entered (the factory value turns off the sleep state. If you need to sleep, please set F09.27=3). After entering the sleep state, the 343
