Possible causes
1 No Control deviation:
Actual value re‐
sponse has excee‐
ded values for TIM
and LIM
Always active ... the actual value response
falls below the value for LIM
Supply pressure PZ missing,
actuator fault, process valve
fault (e.g. blockage).
2 No Device not in "Au‐
tomatic" mode
**. FCT
1)
= nA or = nAB
... the device is changed to
"Automatic" mode.
The device has been config‐
ured or is in the manual mode
3 No Digital input BIN1
or BIN2 active
**. FCT
1)
= nAB and digital
function BIN1 or
BIN2 to "On"
... the digital input is no longer
activated.
The contact connected to the
digital input was active (e.g.
packing gland monitoring,
overpressure, temperature
switch).
4 Yes Limit for number of
total strokes ex‐
ceeded
L. STRK≠OFF ... the stroke counter is reset
or the thresholds are in‐
creased
The total path covered by the
actuator exceeds one of the
configured thresholds.
5 Yes Limit for number of
changes in direc‐
tion exceeded
O. DCHG≠OFF ... the counter for changes of
direction is reset or the thresh‐
olds are increased.
The number of changes of di‐
rection exceeds one of the
configured thresholds.
6 Yes Lower endstop lim‐
it exceeded
F. ZERO≠OFF
**.YCLS = do or up
do
... the deviation of the endstop
disappears or the device is re-
initialized.
Wear and tear of the process
valve, deposits or foreign bod‐
ies in the process valve, me‐
chanical misalignment, fric‐
tion clutch moved.
7 Yes Upper endstop lim‐
it exceeded
G. OPEN≠OFF
**.YCLS
1)
= do or
up do
... the deviation of the endstop
disappears or the device is re-
initialized.
Wear and tear of the process
valve, deposits or foreign bod‐
ies in the process valve, me‐
chanical misalignment, fric‐
tion clutch moved.
8 No Deadband limit ex‐
ceeded
E. DEBA≠OFF
**.DEBA
1)
= Auto
... the limit is undershot again Increased packing gland fric‐
tion, mechanical gap in the po‐
sition feedback.
