Faults during commissioning
Table 19:
Faults during operation/commissioning
Remedy
Description/cause
Faults
Change speed.
Speed setting is incorrect.
Actuator operation is either too fast
or to slow.
Set speed reduction and/or adapt parameter.
Speed reduction switched off or incorrectly set be-
fore reaching end positions.
Actuator suddenly stops in end posi-
tions.
Replace position indicator.
Incorrect position indicator selection when placing
the order.
Mechanical position indicator stops;
however, the actuator continues oper-
ation. This can cause the position in-
dicator to break.
Open blanking plugs with screwdriver.
●
Position indication disc jams at the top (end
position OPEN):
Briefly turn the spindle shaft with slotted
screwdriver clockwise.
●
Position indication disc jams at the bottom (end
position CLOSED):
Briefly turn the spindle shaft with slotted
screwdriver counterclockwise.
In relation to the actuator stroke range, the position
indicator has been incorrectly set. This causes the
position indicator to be pressed to the end stop and
the slip clutch is activated. The position indication
disc jams in the event of high speeds.
The position indication disc jams at
the upper or lower edge of the posi-
tion indicator and does no longer
move in the event of a change of dir-
ection.
Operate the actuator sufficiently in opposite direc-
tion.
Open blanking plugs with screwdriver.
Press down the end position indication ring using
a screwdriver and approach again the end position,
ensuring that the end position indication ring is
pushed to the end position by the position indication
disc.
The setting range of the position indication disc is
larger than the actual stroke range of the actuator.
The yellow position indication disc
stops before the end position indica-
tion ring.
Advance electronic end position switch by the
overrun margin or adapt the parameters to an ex-
tended speed reduction curve in the “Speed
red.pr.end pos.” [speed reduction prior to end pos-
ition] section.
Overrun due to excessive speed.
Actuator exceeds the end position.
Adapt the speed reduction prior to setpoint position
parameters to an extended speed reduction curve
in the positioner menu or adjust optimally the
parameters for the positioner.
Overrun due to excessive speed.
Actuator repeatedly corrects the set-
point position during positioning.
10.2.
Fault indications
Faults interrupt or prevent the electrical actuator operation. If a fault occurs, the
FOX-EYE indication light is quickly flashing in red.
Warnings have no influence on the electrical actuator operation. They only serve
for information purposes. The FOX-EYE remains white.
Collective signals include further indications. The FOX-EYE remains white.
Faults and warnings may exclusively be read via AUMA Assistant App or AUMA
CDT software.
