8 Malfunctions
The malfunctions listed in Table 4 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 re-
pair 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 9.1.
