Error message
disappears if...
Possible
causes
1 no Remaining control
deviation
always active ... the control
deviation has
disappeared again.
Compressed air
missing, actuator
fault, valve fault
(e.g. blockage).
2 no Device not in
automatic mode
47. FCT= nA
or = nAB
... the device is
switched to automatic
mode.
The device is
configured or is in
manual mode.
3 no Binary input BE1
or BE2 active
47. FCT= nAB
and binary function
BIN1 or BIN2 at “on”
... the binary input is
no longer activated.
The contact
connected to the
binary input became
active (e.g. stuffing
box monitoring,
overpressure,
temperature switch).
4 yes Limit
Stroke number
exceeded
L. STRK¸OFF
... the stroke counter
is reset or the
thresholds are
increased
The sum of the
distance covered by
the actuator exceeds
one of the set
thresholds.
5 yes Direction change
limit exceeded
O. DCHG¸OFF
... the direction
change counter is
reset or the
thresholds are
increased
The number of
changes of direction
exceeds one of the
set thresholds.
6 yes Lower limit stop
limit exceeded
F. ZERO¸OFF
39.YCLS = do or up
do
... the deviation of the
stop disappears or
the device was
re-initialized.
Wear of the valve
seat, deposit or
foreign matter in
the valve seat,
mechanical
misadjustment, friction
clutch misadjusted.
7 yes Limit
of upper limit stop
exceeded
G. OPEN¸OFF
39.YCLS = up or up
do
... the deviation of the
stop disappears or
the device was
re-initialized.
Wear of the valve
seat, deposit or
foreign matter in
the valve seat,
mechanical
misadjustment, friction
clutch misadjusted.
8 no Limit
Dead zone
adaptation
exceeded
E. DEBA¸OFF
34.DEBA = Auto
... the value has
fallen below the limit
again.
Increased stuffing box
friction, mechanical
batches of the
position feedback.
9 yes Partial stroke test
exceeds reference
step time
A. PST¸OFF
... a partial stroke test
is performed
successfully within
the reference step
time or the function is
deactivated.
Valve jams or is
rusted in place,
increased friction
10 yes General control
valve malfunction
b. DEVI¸OFF
... the position is back
within a narrow
corridor between
guide value and
model, or the function
is deactivated.
actuator fault, valve
fault, valve jams,
increased friction,
compressed air drop
11 yes Pneumatic leakage C. LEAK¸OFF ... the leakage falls
below the set
thresholds, or the
function is
deactivated.
