Configuration Short description
SIL seating type
1: No seating No seating by limit or torque switches dur-
ing safety operation
2: Forced torque seat- Safety operation is stopped if both limit and
ing in end position torque switches trip simultaneously
3: Forced limit seating Safety operation is stopped by limit switch
in end position tripping
4: Limit seating with Safety operation is stopped by tripping the
overload protection limit switches and/or the torque switches
(overload protection).

Table 7: Configuration options for motor protection assessment
Configuration Short description
SIL motor protection
Active Tripping of the motor protection (thermal fault) stops or prevents safety
operation
Inactive Motor protection has no impact on the safety operation
"SIL motor protection" = "inactive" configuration is only set if explicitly required. The
version does not meet the Ex approval requirements.
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
