What are the adjustment methods and techniques for setting the zero point and range of the control card during the debugging process?
FAT, try them one by one. Dear OP, at least 25% is required; try them one after another
When it is necessary to adjust the zero point of the control card, the key is to check whether the output current corresponds to the actual movement of the valve. For example, when adjusting the valve over a range of 0% to 30% of its travel, an output current of 4 mA corresponds to a valve opening of 0%, while an output current of 20 mA corresponds to a valve opening of 100%. Ensuring that the valve opens and closes in the correct direction, one first determines the zero point and then adjusts the range. By repeatedly fine-tuning the zero point and the range, it is ensured that the valve operates linearly and stably, which in turn guarantees that the valve’s zero point and range remain accurate and reliable during use.
