When configuring a Safe ESD function and a Safe STOP function, the Safe ESD
function is always prioritised compared to the Safe STOP function when requested
simultaneously.
Seating configuration options
Seating of standard actuator controls should be configured as set forth in the tables

For actuators with electromechanical control unit:
Configuration Short description
SIL seating type
1 = No seating No seating by limit or torque switches during
safety operation
2: Forced torque seating Safety operation is stopped if both limit and
in end position torque switches trip simultaneously
3: Forced limit seating in Failure operation is stopped by limit switch trip-
end position ping
4: Limit seating with Failure operation is stopped by tripping the limit
overload protection switches and/or the torque switches (overload
protection).
