The power supply of Rosemount 1700 is 24V DC and cannot be used.

1700 series, analog output. Use the calibrator to power 24V and connect it to pins 9 and 10 of the flow meter, but only 2 small lights flash on the flow meter and there is no display on the display. Is the power supply insufficient? Does it have to be 220V AC? ? ? Flowmeter 1700 series, integrated. DCS requires a 4-20m A 1,2 point signal from the flow meter.
Sorry for posting this post to insult all seniors. I didn't find the manual (on CD) beforehand. After reading the manual, it seems that the 24V power supply needs to be preheated. The power consumption is relatively large, or something. In short, it takes about ten minutes to preheat. I'm so sorry. This is my first time using it, please understand.
The main reason is that although the test instrument can reach 24V voltage, its power is not enough to carry some equipment on site. We have encountered such a problem before. Let’s see if you have a PLC cabinet or other active power supply.
