How to handle a PERR error on a switch valve?

2010-08-17View Original

Thread Content

I’m not sure what’s going on. The travel distance of both valves is 1, but when this error occurred, the valves on site were already open; yet the PV value remained at 0, with only this error being displayed. How is this problem usually resolved?

It should refer to an overflow in the on-site response switch signal – either two 0s or two 1s. Check the response signal; one of them should be incorrect
