Redundant system architecture
Installation, commissioning and operation
Status indications on SIL functions
SIL fault signal via standard controls display (for troubleshooting support)
Status signals via output contacts (digital outputs) of standard controls
Signal via fieldbus of standard controls
Internal actuator monitoring with control via standard controls
Partial Valve Stroke Test (PVST): execute
Proof test (verification of safe actuator function)
Safe ESD safety operation “Safe OPENING/CLOSING”: check
SIL fault signal “Actuator monitoring”: check
Safe ESD reaction for “Motor protection (thermal fault)” signals: check
Safe ESD reaction to “Limit seating with overload protection” (limit and/or torque
evaluation): check

for actuators with electromechanical control unit
Safe ESD reaction to “Forced limit seating in end position” (limit evaluation) – for
actuators with electronic control unit and limit switches: check
