Indication on display Description/
Standard controls cause of fault
Thermal fault Motor protection tripped.
Torque fault CLOSE Torque fault in directions
CLOSE or OPEN
Torque fault OPEN
Torque fault in directions
CLOSE and OPEN (simultan-
eously).
Wrn range act.pos. Current position feedback sig-
nal range is outside the per-
missible range.
Both limit switches (OPEN and
CLOSED) are operated simul-
taneously.
Possibly defect at actuator
mechanics.
Phase fault One phase of power supply is
missing.
Controls are not supplied with
mains voltage
Incorrect phase seq The phase conductors L1, L2
and L3 are connected in the
wrong sequence.

The integrated SIL module signals a SIL fault via an output contact (
or SIL failure outputs). Only these signals may be used in a safety-related
system.
For the signal behaviour of the
<Installation> chapter.
Once a SIL fault occurs, the system has to be checked immediately and the
installation has to be put in a safe state, if required.
If the SIL module output contact (
a SIL fault, the exact fault can be determined via the indication in the standard controls
display. For details on all fault indications and warning indications on the standard
controls display, refer to Manual (Operation and setting) AUMATIC AC 01.2.
The SIL module output contact serves as collective signal for the faults listed in the
table below.
Impact on safety function
→ Remedy
For version SIL motor protection" = active:
Remedy
→ Cool down, wait.
For SIL seating" = "Limit seating with overload protection"
configuration:
Remedy
→ Execute operation command in opposite direction.
→ Verify torque switching setting.
→ Check whether foreign object prevents the valve from closing.
→ Possibly problems with the valve.
For configurations SIL seating" = Limit seating with overload
protection", SIL seating" = Forced limit seating in end posi-
tion", or SIL seating" = Forced torque seating in end position":
Remedy
→ Verify reduction gearing settings within the actuator.
→ In case of possible defect at the actuator: Contact AUMA service
Remedy
→ Test/connect phases.
In case of wrong phase sequence, the actuator is operated into the
wrong direction during safety operation.
Remedy
→ Correct the sequence of the phase conductors L1, L2 and L3 by
exchanging two phases.

The Safe ESD safe function cannot be executed.
If the fault is triggered during safety operation, operation is
stopped.
The Safe ESD safe function cannot be executed.
If the fault is triggered during safety operation, operation is
stopped.
The Safe ESD safe function cannot be executed.
If the fault is triggered during safety operation, operation is
stopped.
The Safe ESD safe function cannot be executed.
The Safe STOP safe function is indirectly executed as the motor
is no longer supplied with power.
