Hello,
I'm working on a project and we are using Fisher DVC6200 SIS as the valve controller. For the blowdown valves the EPC has specified "energize to trip" valves. In the P&ID these valves are identified as "Fail Open".
Reading through the documentation Quick start guide (D103556X012), on page 42 there is a functionality described as "Energize to Trip (ETT) Digital Valve Controller and De-Energize to Trip (DETT) Solenoid Valve".
My question is the following: does the "Energize to Trip (ETT) Digital Valve Controller and De-Energize to Trip (DETT) Solenoid Valve" is the equivalent of "Energize to trip and Fail Open"?
Regards,
Cristobal
