Fault indications and warning indications
Faults interrupt or prevent the electrical actuator operation.
Faults and warnings can be signalled via the two output contacts and/or via the local
controls.
Should local controls be available, the fault and warning signals are indicated by the
left indication light [1].
Figure 28: Fault indications and RESET

Red indication light: Fault, yellow: Warning
[2]
Push button RESET
In operation mode LOCAL (right indication light is blinking in blue), stored faults
(cause does no longer exist), may be reset using the push button RESET [2] (hold
it down for more than 1 second).
The tables below show the fault signalling via the indication lights of the local controls.
Table 12: Fault signalling via the red indication light
Signification (default)
Signal
Indication
Torque fault
→
Press push buttons OPEN or CLOSE to re-
set the fault (indication light) by operating the
device in the opposite direction.
Fault indication 1
1 blink
Thermal fault (motor protection tripped)
→
Cool down, wait.
Fault indication 2
2 blinks
Signal loss of analogue input (4 – 20 mA)
Fault indication 3
3 blinks
Operation mode DISABLED: Operation via the
local controls is disabled (Enable local controls
function).
Fault indication 4
4 blinks
Fault E2 (actual value of positioner)
→
Check wiring (for possible loss of signal) of
E2.
→
Read detailed fault indication via AUMA
CDT software (accessories).
Fault indication 5
5 blinks
Actuator is outside the permissible position
(potentiometer signal).
→
Set potentiometer again.
Fault indication 6
6 blinks
Fault of controls temperature
Fault indication 7
7 blinks
Collective signal: Internal error has occurred.
→
Read detailed fault indication via AUMA
CDT software (accessories) and contact
AUMA service.
Fault indication 8
8 blinks
Collective signal for all other faults
Fault indication 9
9 blinks
In case several faults have occurred, only the fault with the highest priority will be
signalled. Fault indication 1 has the highest, fault indication 9 the lowest priority.
