If electronic safety switching devices are used for pressure limiting, the setting
may deviate from the standard specifications (see EN 378-2) due to the
increased precision.
Notice
When using safety valves for pressure relief, the operator is responsible for:
► dimensioning of the piping,
► safe discharge of refrigerant when the pressure relief device is triggered.
The safety devices for pressure limiting according to EN 378-2 are the minimum
requirements. Before commissioning, the requirements specified in the local
operational safety regulations must therefore be compared with those of EN
378-2.
The specified test intervals must be observed to ensure proper functioning of the
safety devices for pressure limiting. They are specified in the respective opera-
tional safety regulations.
