SIL motor protection
Tripping of the motor protection (thermal fault) stops or prevents safety
operation
Active
Motor protection has no impact on the safety operationInactive
Information "SIL motor protection" = "inactive" configuration is only set if explicitly required.The
version does not meet the Ex approval requirements.
3.3. 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
sheets:
●
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 test, 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
