3.4.6 If the device is in Shutdown
When the device is in Shutdown an internal failure
has occured.
If the internal failure is re-solved, the actuator shut-
down status can be manually reset.
1 Normally the SHUTDOWN_RESET parameter is
inactive. For reseting the shutdown status param-
eter SHUTDOWN_RESET must be set to Reset.
2 When this reset is completed succesfully, the
SHUTDOWN_STATUS parameter will be FieldQ
operational and SHUTDOWN_RESET parameter
will return to inactive.
If you do not want to manually reset the device, you
can set the device to Auto-Recovery as described in
4.2.3.3.
If the problem persists, please contact your local
FieldQ representative.
3.4.4 If the "Open" or "Closed" feedback is
lost.
1 Check if the actuator/valve unit is working correctly.
2 If it is safe to cycle the actuator, perform the
initialization procedure (see §3.2).
3 If it is not safe to cycle the actuator, perform the
following procedure:
1 Go to Transducer block.
2 In case the "Open" position is lost:
Set sub parameter OPEN_END_POSITION of
parameter CFG_SWITCH_POINTS to:
"set to current position".
3 In case the "Closed" position is lost:
Set sub parameter CLOSE_END_POSITION of
parameter CFG_SWITCH_POINTS to:
"set to current position".
Note:
- If the problem is persistent, increase the endstop
offset (see 4.2.3.2).
3.4.5 If the initialization can not be started
via the push buttons.
1 Ensure the device is "Out Of Service".
2 Ensure that the buttons are enabled in the trans-
ducer block (parameter
BUTTONBOARD_ENABLE, index 34).
Remark:
Setting the device to default will always enable the
push buttons as long as the device is in "Out Of
Service" (see §3.4.1).
3 Ensure that the unit is not in Shutdown. See
Transducer block parameter
SHUTDOWN_STATUS, index 32. If the device is in
Shutdown see 3.4.6
