Thank you very much. Two valves failed on our boiler and I had to install two of these on an emergency basis. Your videos were very helpful and helped us get up and running sooner. I was pretty stressed because I hadn't set up a positioner exactly like this. Thanks again.
It's not ATVP but ATYP, short for 'Actuator Type'. 1-A for single acting. VTVP is actually VTYP for 'valve type'. Rot for rotary type of valve. PFA: positioner failed action. Set as failed OPEN by the demonstrator. Despite the short form used, I find them intuitive.
