Troubleshooting Guide:
This guide will assist in troubleshooting common issues that one could encounter under normal operation. Before
beginning any troubleshooting or service, please remove all sources of potential energy
(trapped nitrogen pressure or trapped line pressure) if possible.
ISSUE SOLUTION
1
Wellhead Pressure reading -5000PSI.
1) User is on wrong Valve tab.
2) “Y Cable” from Control case is not installed correctly.
3) 250’ Cable not plugged into Stainless Box or “Y Cable.”
4) Cable from pressure transducer not plugged into Stainless
Box.
5) Inspect cables for cuts that could damage wiring. If so,
contact your SPM ARC representative.
2 Bottle Pressure showing -250PSI.
1) User is on wrong Valve tab.
2) “Y Cable” from Control case is not installed correctly.
3) 250’ Cable not plugged into Stainless Box or “Y Cable.”
4) Inspect cables for cuts that could damage wiring. If so,
contact your SPM ARC representative.
3
Valve will not reach “Dome Ready”
state.
(
The system set point has been set but the
“Dome Ready” indicator will not illuminate.)
1) Hose from stainless box to Dome Valve is not connected.
2) Ensure all connections are leak free.
3) Nitrogen Bottle pressure is insufficient to supply required
dome set point. Verify that the Bottle Pressure warning is
not present on the user interface. If present, replace bottle.
4) If issue is still unresolved, contact your Weir ARC
representative.
4
System will not dump pressure when
reaching “Pop Off Set point.”
1) All conditions have not been met for a pop off event i.e. Pop
Off Filter Duration. Pop ‐ off Filter is an interval of time, in
milliseconds (rounded down to the nearest 5 ms). If the
wellhead pressure stays above the Pop ‐ Off Set point for Pop ‐
off Filter, the system triggers a pop ‐ off.
2) Nitrogen vent in bottom of Stainless Box is clogged.
3) If issue is still unresolved, contact your Weir ARC
representative.
5
Pressure sensors are not zeroed.
1) Contact management to enter password that allows zero
calibrations.
2) If issue is still unresolved, contact your Weir ARC
representative.
6
Box will not power up.
1) Check to make sure plug is inserted fully into outlet source.
2) If power circuit feeding box is GFCI protected, make sure the
circuit interrupter has not tripped.
3) Check circuit breaker that feeds box to ensure it is not
tripped.
4) If issue is still unresolved, contact your Weir ARC
representative.
