SQEx 05.2 SQEx 14.2/SQREx 05.2
Description/cause
SIL sub-assembly fault has occurred.
Execution of PVST (Partial Valve Stroke Tests) is
required.
Maintenance is required.
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.
Due to insufficient mains quality, the controls cannot
detect the phase sequence (sequence of phase
conductors L1, L2 and L3) within the pre-set time
frame provided for monitoring.

Manual (Operation and setting).
Perform one of the following measures:
Issue operation command in direction OPEN.
Set selector switch to position Local control
(LOCAL) and reset fault indication via push
button RESET.
Execute reset command via fieldbus.
Perform one of the following measures:
Issue operation command in direction CLOSE.
Set selector switch to position Local control
(LOCAL) and reset fault indication via push
button RESET.
Execute reset command via fieldbus.
Test/connect phases.
Correct the sequence of the phase conductors L1,
L2 and L3 by exchanging two phases.
Check mains voltage.
For 3-phase/1-phase AC current, the permiss-
ible variation of the mains voltage is ±10 %
(option ±30 %). The permissible variation of the
mains voltage is ±5 %
Check parameter Tripping time M0172, extend
time frame if required.
