7 Malfunctions
The malfunctions listed in Table 10 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 for repair work.
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 department
can help during troubleshooting. Further in-
formation is available in section 9.
SAMSON's After-sales Service department
