APPENDIX B
VALVE PROVING SYSTEM
The S7800A1167 display is required to set up this feature.
Valve Proving System feature provides a systematic way of
testing the valve seat integrity to assure the valves are indeed
in the closed state when the system is off line—in Standby.
At commissioning time, the Valve Proving System may be
scheduled to occur at one of five different times: Never, Before,
After, Both, and Split.
• Never—Device Default as received; in this case Valve
Proving does not occur.
• Before—Valve Proving occurs prior to ignition trials.
• After—Valve Proving occurs after the Run state; before the
internal Safety Relay dropout state.
• Both—Valve Proving occurs at both times Before and After
noted above.
