Fault codes and troubleshooting methods for the Chuanyi HVP11 intelligent valve positioner: Compiled based on the WeChat official account “Instrument News”. Fault Code, Cause of Fault, Solution ~ Alarm due to interrupted feedback signal: Check the feedback rod and feedback potentiometer. ~1 Alarm when the signal exceeds the upper or lower limits: Check the installation angle and value of the feedback rod. ~2 If the installation angle does not meet the requirements, adjust it to the allowable range. ~3 Air leakage: Check the actuator, air supply lines, IP unit, etc., to identify and fix any leaks. ~4 If the 6-step self-check fails, it is a problem with the piezoelectric valve; in case of an IP unit fault, replace the IP unit. ~5 Motherboard failure: Replace the motherboard
It was a product from 5 years ago; it had a high failure rate, and most units were replaced with different models. I don’t know how the product is now. My standard is roughly: for 30 units over 3 years, no more than 2 units may fail due to defects in the product itself.
I haven’t used CHUANYI products yet, but I think they should be good
