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 10.1.

We recommend removing the regulator from 
the pipeline before repairing it.

SAMSON's After-sales Service department 
can support you in drawing up an inspection 
and test plan for your plant.

Contact SAMSON's After-sales Service de-
partment for malfunctions not listed in the ta-
ble.
