Applications (environmental conditions)

When specifying and using the actuators within safety instrumented systems, make
sure that the permissible service conditions and the EMC requirements by the
peripheral devices are met. Service conditions are indicated in the technical data
sheet:
Enclosure protection
Corrosion protection
Ambient temperature
Vibration resistance
If the actual ambient temperatures exceed an average of +40 °C, the lambda values
have to be incremented by a safety factor. For an average temperature of +60 °C,
this factor is specified to 2.5.
For environmental tests, actuator and actuator controls were subjected to the following
standards:
Dry heat: EN 60068-2-2
Damp heat: EN 60068-2-30
Cold: EN 60068-2-1
Vibration test: IEC 60068-2-6
Induced seismic vibration (earthquake): IEC 60068-3-3
Enclosure protection test IP68: EN 60529
Salt spray test: EN ISO 12944-6
Immunity requirements: EN 61326-3-1
Emission: EN 61000-6-4
