AUMA ACVExC 01.2 Series User Manual

●
If the setting range was limited for the positioner (parameter Limit setting
range M0845 = Function active)
For actuator controls in SIL version, we DISADVISE using the automatic deblocking
function.
Unexpected starting of actuator!
When using automatic deblocking with level-controlled operation command evaluation,
unexpected starting of actuator into the wrong direction might occur when trying to
eliminate a double-sided torque fault (torque faults in directions OPEN and CLOSE
are present at the same time).
→
Use automatic deblocking only in combination with edge controlled operation
command evaluation (parameter Com. eval. REMOTE M1709).
Characteristics
In case of torque switch tripping in intermediate position (i.e. prior to reaching the
end position), the actuator automatically attempts to reach the end position by
operation into the opposite direction and executing the actual operation command
once again.
The torque fault signal is suppressed during automatic deblocking. Should torque
switching trip again once automatic deblocking is complete, the actuator is switched
off and actuator controls signal a torque fault.
