10.1 Faults during commissioning
Table 9: Faults during commissioning
RemedyPossible causesFault description
Exchange reduction gearing.Reduction gearing is not suitable for
turns/stroke of the actuator.
Mechanical position indicator
cannot be set.
Determine overrun: Overrun = travel covered
from switching off until complete standstill.
Set limit switching again considering the
overrun (turn handwheel back by the amount
of the overrun).
The overrun was not considered when setting
the limit switching.
The overrun is generated by the inertia of
both the actuator and the valve and the delay
time of the controls.
Fault in end position
Actuator runs to end stop alt-
hough the limit switches work
properly.
Exchange reduction gearing.Reduction gearing is not suitable for
turns/stroke of the actuator.
Position transmitter RWG
Measurement range 4 – 20 mA
or maximum value 20 mA cannot
be set.
Check setting, if required, reset end positions.
→ Check switches and replace them, if requi-
red.
Switch is defective or switch setting is incor-
rect.
Limit and/or torque switches do
not trip.
For RESTRICTED: A release must be initia-
ted externally via bus or input signal. Refer
to parameter Enable LOCAL MODE.
For EMERGENCY STOP: Release EMER-
GENCY STOP button.
RESTRICTED signifies that the local con-
trols of the AUMATIC have not been released
yet.
EMERGENCY STOP signifies that the
EMERGENCY STOP mode has been activa-
ted via the EMERGENCY STOP button (opti-
on),
Push buttons do not react
The controls may not be operated
via the local controls.
Display indicates: RESTRIC-
TED or EMERGENCY STOP.
Switch check
The red test buttons [1] and [2] are used for manual operation of the switches:
1. Turn test button [1] in direction of the TSC arrow:Torque switch CLOSED trips.
The indication light for torque fault CLOSED on the local controls is illuminated.
2. Press push button OPEN to reset the fault (indication light) by operating the
device in the opposite direction.
3. Turn test button [2] in direction of the TSO arrow: Torque switch OPEN trips.
The indication light for torque fault OPEN on the local controls is illuminated.
4. Press push button CLOSE to reset the fault (indication light) by operating the
device in the opposite direction.
If the actuator is equipped with a DUO limit switching (option), the intermediate
position switches (LSA and LSB) will be operated at the same time as the torque
switches.
1. Turn test button [1] in direction of the LSC arrow: Limit switch CLOSED trips.
2. Turn test button [2] in direction of the LSO arrow: Limit switch OPEN trips.
10.2 Fault indications and warning indications
Faults interrupt or prevent the electrical actuator operation.
Warnings have no influence on the electrical actuator operation.They only serve
for information purposes.
Fault and warning indications are shown in the display.
