Troubleshooting

8.3.1 Problems with position feedback/indication E2 (from actuator)

8.3.2 Display hardly readable or illegible

8.3.3 Actuator does not run

8.3.4 Actuator does only operate from local

8.3.5 Actuator is not switched off by limit seating in direction CLOSE or OPEN

Ò Check
FEEDBACK E2
Value must correspond to the installed position transmitter.
Ò Check
I/O1 ANALOG OUT1
Value must correspond to wiring diagram.
Ò Check
I/O ANLOG OUT1 TYPE
Value must correspond to desired feedback.
Ò Check fieldbus configuration
Ò Check diagnostic indications
tion transmitter installed in the actuator):
The value in the upper line is the raw value in the end position CLOSED,
the value in the bottom line is the raw value in the end position OPEN
while the value in the middle line is the current position transmitter raw
value (it must change evenly throughout the complete stroke when the
output drive shaft is turning).
Ò For torque seating:
Set limit end position as close as possible to torque switching off point
Ò Check galvanically isolated 24 V DC supply of the position feedback
Ò Check AUMATIC 24 V voltage supply (e.g. when switching on, all LEDs
of the local controls must briefly light up, if necessary, check fuses).
Ò Change LCD contrast (for green display only). For this, change
CONTRAST(M011)
display) .
Ò Check motor voltage supply.
Ò Check AUMATIC 24 V voltage supply (e.g. when switching on, all LEDs
of the local controls must briefly light up, if necessary, check fuses).
Ò Check fault signals (status indication
Actuator cannot be operated when fault signals have occurred.
Ò Check setting of
I/O STACK 1 (M4106)
