Does anyone know what's wrong here? My current job task is to control the HVA converter(10HVA24-N1-BNC-10KV, Ultravolt) through NI-9263, so as to output 0-10kV voltage to control DMA. However, we have encountered challenges in utilizing these products.
We used pin 1 of HVA converter as the reference voltage pin, and we provided it with a voltage of 10V by NI-9263 ao1. Pin 2 was assigned as the voltage output control pin, and we applied a stepped voltage ranging from 0-10V (such as 1, 3, 4, 6, 8V) by NI-9263 ao2. Additionally, we connected pins 6 and 3 together as the signal ground terminal. Furthermore, the power supply voltage of pin 8 and pin 9 is 24V, provided by a switching power supply that can provide up to 35W. (We assumed the HVA converter only absorbes 1W ).
We connected pin 11 to pin 1 as enable input for convenience , which required more than 2.4V for enable. And all the voltage output signal return grounds were the return of each ao in NI-9263.
Despite these efforts, when measuring the product's output voltage using a voltage divider, we consistently obtained a reading of 0V, which should be 0-10kv corresponding to 0-10V of ao output. Additionally, the feedback voltage measured at pin 4 was also approximately 0V.
