8.3 Troubleshooting
8.3.1 Problems with position feedback/indication E2 (from actuator)
Ò
Chec
k
FEEDBACK E2 (M4101) parameter, page 31):
Value must correspond to the installed position transmitter.
Ò
Check
I/O1 ANALOG OUT1 (M410A) parameter:
Value must correspond to wiring diagram.
Ò Check
I/O ANLOG OUT1 TYPE (M410A) parameter:
Value must correspond to desired feedback.
Ò Check fieldbus configuration
Ò Check diagnostic indications
D7 or D8 (depending on the type of posi-
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
8.3.2 Display hardly readable or illegible
Ò Chec
k 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
LCD
CONTRAST(M011)
parameter (the higher the value the darker the
display)
.
8.3.3 Actuator does not run
Ò Chec
k 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
S1 or diagnostic indication D2 ).
Actuator cannot be operated when fault signals have occurred.
8.3.4 Actuator does only operate from local
Ò Chec
k setting of
I/O STACK 1 (M4106). The setting must corre-
spond to wiring diagram.
Ò Check
NOT READY IND. (status indication S3) indication.
8.3.5 Actuator is not switched off by limit seating in direction CLOSE or OPEN
The actuator is set to torque seating.
Set actuator to limit seating:
Ò Set par
ameter
CLOSED POSITION (page 45) to LIMIT.
Ò Set parameter
OPEN POSITION (page 45) to LIMIT.
