Overview of error codes

Overview of error codes that activate the fault message output
Error Three- Event
code stage
1 No Control deviation:
Actual value re-
sponse has ex-
ceeded values for
TIM and LIM
2 No Device not in "Au-
tomatic" mode
3 No Binary input BIN1
or BIN2 active
4 Yes Limit for number of
total strokes ex-
ceeded
5 Yes Limit for number of
changes in direc-
tion exceeded
6 Yes Lower endstop
limit exceeded
7 Yes Upper endstop
limit exceeded
8 No Deadband limit
exceeded
9 Yes Case 1: Reference
stroke time for
partial stroke test
is exceeded.
Case 2: Start posi-
tion outside the
start tolerance

L. STRK≠OFF ... the stroke counter is reset
or the thresholds are in-
creased
O. DCHG≠OFF ... the counter for changes of
direction is reset or the
thresholds are increased.
F. ZERO≠OFF ... the deviation of the end-
stop disappears or the device

E. DEBA≠OFF ... the limit is undershot again
**.DEBA = Auto
1)
A. PST≠OFF Case 1: ... a partial stroke test
is successfully executed
within the reference stroke
time or the function is deac-
tivated.
Case 2: Move the actuator
into the range of the PST
start tolerance. Or increase
the PST start tolerance until
the actuator (PST start posi-
tion) is within the PST start
tolerance. Start the partial
stroke test again.
Possible causes
Compressed air failure, actu-
ator fault, valve fault (e.g.
blockade).
The device has been config-
ured or is in the manual mode
The contact connected to the
binary input was active (e.g.
packing gland monitoring,
overpressure, temperature
switch).
The total path covered by the
actuator exceeds one of the
configured thresholds.
The number of changes of
direction exceeds one of the
configured thresholds.
Wear and tear of the valve
seat, deposits or foreign bod-
ies in the valve seat, mechan-
ical misalignment, friction
clutch moved.
Wear and tear of the valve
seat, deposits or foreign bod-
ies in the valve seat, mechan-
ical misalignment, friction
clutch moved.
Increased packing gland
friction, mechanical gap in the
position feedback.
Case 1: Valve is stuck or
rusted. Increased stiction.
Case 2: Valve is present in
the safety position.
