6-1. Troubleshooting
The SVP is a precision instrument and requires the same level of care as any other field device.
Unlike an air-actuated control valve, the SVP contains many electronic components and
mechanical parts which must have proper settings and calibration. Poor SVP performance is
usually easy to correct by adjusting settings.
A Minor Failure indicates no immediate danger or serious trouble in the operation of
the SVP. The SVP will continue to operate normally. Connecting a Commstaff or HART
Communicator or requesting a self-diagnostic through the supervisory monitoring system
(model AVP100/102) is necessary to discover and determine Minor Failures.
A Major Failure indicates serious trouble in the operation of the SVP and, if no action is taken,
may lead to damage to the SVP itself. Should serious trouble occur during SVP operations, the
SVP will drive the valve to the fail-safe position. a Commstaff or HART Communicator, or the
supervisory monitoring system (model AVP102) are used to determine Major Failures.
