the set reaction time.
Limit value for torque warning in direction OPEN
exceeded.
Limit value for torque warning in direction CLOSE
exceeded.
SIL sub-assembly fault has occurred.
Execution of PVST (Partial Valve Stroke Tests) is
required.
Maintenance is required.
FQM fault
Description/cause
Collective signal 11:
Configuration error has occurred.
Collective signal 22:
Configuration error has occurred.
Collective signal 14:
Internal error has occurred.
Torque fault in direction CLOSE
Torque fault in direction OPEN
When connecting to a 3-ph AC system and with
internal 24 V DC supply of the electronics:
Phase 2 is missing.
When connecting to a 3-ph or 1-ph AC system
and with external 24 V DC supply of the elec-
tronics: One of the phases L1, L2 or L3 is
missing.
The phase conductors L1, L2 and L3 are connected
in the wrong sequence.
Only applicable if connected to a 3-ph AC system.
SAR 16.2 Control unit: electronic (MWG)
AC 01.2 Non-Intrusive EtherNet/IP
Remedy
Perform RESET or restart PVST.
Check movement at actuator.
Check parameter Reaction time M0634.
Check parameter Wrn torque OPEN M0768, re-set
if required.
Check parameter Wrn torque CLOSE M0769, re-
set if required.
Refer to separate Manual Functional Safety.
Checking and fault remedy are required. Refer to
FQM operation instructions.
