How to change the feedback for the Metso locator NDP1510
Thread Content
Besides adjusting up and down
What’s the problem? Please explain in detail!
4 milliamps when on, 20 milliamps when off; the corresponding feedback is 100% at 4 milliamps and 0% at 20 milliamps. However, the feedback I get is 0% at 4 milliamps and 100% at 20 milliamps
If I correct the reaction, the feedback is correct; but it becomes a 4-millimeter safety shutdown and a 20-millimeter safety activation
In the case of the forward and reverse action of a valve, it is usually sufficient to set the signal direction; feedback is based on the valve’s opening degree and no configuration is required. The valve position for 4MA fully closed is the same as that for 20MA fully closed – both are 0
Just change the forward/reverse action of the valve position output in the system configuration
