Malfunctions
Themalfunctionslistedinsection8.1 are
caused by mechanical faults and incorrect
regulatorsizing.Inthesimplestcase,the
functioning can be restored following the
recommended action. Special tools may be
required to rectify the fault.
Exceptional operating and installation condi-
tions may lead to changed situations that
may affect the control response and lead to
malfunctions. For troubleshooting, the condi-
tions, such as installation, process medium,
temperature and pressure conditions, must
be taken into account.
SAMSON's After-sales Service can support
you in drawing up an inspection and test
plan for your plant.
Tip
8.2 Emergency action
Plant operators are responsible for emergen-
cy action to be taken in the plant.
We recommend removing the regulator from
the pipeline before repairing it.
In the event of a regulator malfunction:
1. Closetheshut-offvalvesupstreamand
downstream of the regulator to stop the
processmediumfromowingthrough
the regulator.
2. Perform troubleshooting (see sec-
tion8.1).
3. Rectify those malfunctions that can be
remedied based on the instructions pro-
videdhere.ContactSAMSON'sAf-
ter-sales Service in all other cases.
