16.16 Release of the local controls (option)
Operation of the actuator with the push buttons
OPEN-STOP-CLOSE-RESET of the local controls can be disabled or
released via the digital input RELEASE (see wiring diagram ACP).
Disable local operation: no signal at input RELEASE
Release local operation: connect signal at input RELEASE
To be able to operate the push buttons, the selector switch of the local
controls must additionally be in position LOCAL.
In combination with a fieldbus interface the release of the local controls is
done via the bus. See operation instructions AUMATIC AC 01.1 Profibus DP
or AUMATIC AC 01.1 Modbus.
17. Faults and warnings
17.1 Faults
Faults interrupt or prevent the electrical operation of the actuator. Faults are
indicated in the status indication (page 25) and can be called up there.
Depending on the fault and the setting of the AUMATIC a signal is sent by
the fault relay (see page 30, parameter "
ALARM CONTACT
").
Additional information can also be called up via the diagnosis indication
(page 48).
17.2 Warnings
Warnings have no influence on the electrical operation of the actuator. They
serve only information purposes.
Warnings are indicated in the status indication (page 26) and can be called
up there. Additional information can also be called up via the diagnosis
indication (page 48).
Depending on the setting of the AUMATIC warnings are signalised by the
fault relay (see page 30, parameter "
ALARM CONTACT
").
17.3 Problems with position feedback/indication E2 (from actuator)
.
Check parameter "
FEEDBACK E2
" (
M4101
):
Value must correspond to the installed position transmitter.
.
Check parameter "
I/O1 ANALOG OUT1
" (
M410A
):
Value must correspond to wiring diagram.
.
Check parameter "
I/O1 ANALOG OUT1 TYPE
" (
M410B
):
Value must correspond to required feedback.
.
Check diagnosis pages
D7
or
D8
(depending on the type of position
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)
.
Check galvanically isolated 24 V DC supply of the position feedback
17.4 LCD badly or not readable
.
Check AUMATIC 24 V voltage supply (e.g. all LEDs of the local controls
must briefly light up, if necessary, check fuses).
.
Change LCD contrast parameter "
LCD CONTRAST
" (
M011
) (higher value
= display is getting darker) or see page 19.
17.5 Actuator does not run
.
Check motor voltage supply.
.
Check AUMATIC 24 V voltage supply (e.g. all LEDs of the local controls
must briefly light up, if necessary, check fuses).
.
Check fault signals (status
S1
or diagnosis page
D2
). Actuator cannot be
operated when fault signals have occurred.
