AUMA SQ 05.2 Manual

●
Actuator with electromechanical control unit
●
One of the following safety functions:
- Safe ESD function “Safe CLOSING” (Safe ESD in direction CLOSE)
- Safe ESD function “Safe OPENING” (Safe ESD in direction OPEN)
●
Configuration of “SIL seating”
= “Forced limit seating in end position”
Also valid for combination of Safe ESD with Safe STOP.
