Malfunctions
9 Malfunctions
The malfunctions listed in Table 5 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 can help
during troubleshooting. Further information
is available in Chapter 11.1.
We recommend removing the regulator from
the pipeline before repairing it.
Tip
SAMSON's After-sales Service can support
you in drawing up an inspection and test
plan for your plant.

DANGER
!
Risk of bursting in pressure equipment.
Regulators and pipelines are pressure equip-
ment. Improper opening can lead to bursting
of the regulator.
− Before starting any work on the regulator,
depressurize all plant sections affected as
well as the regulator.
− Drain the process medium from the plant
sections affected as well as from the regu-
lator.
− Wear personal protective equipment.
WARNING
!
Risk of personal injury due to residual pro-
cess medium in the regulator.
While working on the regulator, residual
process medium can escape and, depending
on its properties, may lead to personal in-
jury, e.g. (chemical) burns.
Wear protective clothing, safety gloves and
eye protection.
