Error
code
Three-
stage
Event
Parameter setting
Error message disappears
when
Possible causes
1 No Remaining control
deviation
Always active ... the control deviation
disappears again.
Compressed air failure,
actuator fault, valve fault (e.g.
blockade).
2 No Device not in the
automatic mode
**. FCT
1)
=
nA or = nAB
... the device is switched to
the automatic mode.
The device has been
configured or is in the manual
mode
3 No Binary input BE1
or BE2 active
**. FCT
1)
= nAB and binary
function BIN1 or
BIN2 on "On"
... the binary input is no
longer active.
The contact connected to the
binary input was active (e.g.
packing gland monitoring,
overpressure, temperature
switch).
4 Yes The limit of stroke
number exceeded
L. STRK≠OFF ... the stroke counter is reset
or the thresholds are
increased
The total path covered by the
actuator exceeds one of the
configured thresholds.
5 Yes Limit of changes of
direction exceeded
O. DCHG≠OFF ... the counter for changes of
direction is reset or the
thresholds are increased.
The number of changes of
direction exceeds one of the
configured thresholds.
6 Yes Limit of the lower
hard end stop
exceeded
F. ZERO≠OFF
**.YCLS = do or up
do
... the deviation of the end
stop disappears or the device
is re-initialized.
Wear and tear of the valve
seat, deposits or foreign
bodies in the valve seat,
mechanical misalignment,
friction clutch moved.
7 Yes Limit of the upper
hard end stop
exceeded
G. OPEN≠OFF
**.YCLS
1)
= do or
up do
... the deviation of the end
stop disappears or the device
is re-initialized.
Wear and tear of the valve
seat, deposits or foreign
bodies in the valve seat,
mechanical misalignment,
friction clutch moved.
8 No Limit of deadband
adjustment
exceeded
E. DEBA≠OFF
**.DEBA
1)
= Auto
... the limit is undershot again
Increased packing gland
friction, mechanical gap in the
position feedback.
9 Yes Partial-Stroke-Test
exceeds reference
stroke time
A. PST≠OFF ... a Partial-Stroke-Test is
successfully executed within
the reference stroke time or
the function is deactivated.
Valve jams or has rusted,
increased friction
10 Yes General control
valve fault
b. DEVI≠OFF ... the position is again in a
narrow corridor between the
reference variable and the
model, or the function is
deactivated.
Actuator fault, valve fault,
valve jams, increased friction,
decreased compressed air
11 Yes Pneumatic
leakage
C. LEAK≠OFF ... the leakage drops below
the configured thresholds, or
the function is deactivated.
Pneumatic leakage
