Emergency Action - Samson 2479 Mounting And Operating Instructions

Malfunctions

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 flowing 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.
