Troubleshooting

3.4.1 "Factory default settings", using the
button board.
To set the control module to its factory default set-
tings, do the following;
1 Connect power according chapter 2 and observe
that the Status LED is either on or flashing.
2 Disconnect the power.
3 Press both reassignment buttons.
4 Reconnect power.
5 Status LED goes on.
6 Release the reassignment buttons.
7 Observe that the Status LED indicates that the unit
is in its "Init Default" state (flashing)
3.4.2 If auto initialization (Auto Calibration)
procedure has failed
If the auto initialization (Auto Calibration) has failed,
the status LED on the module will flash and the status
of the AUTO_INITIALIZATION parameter will indicate
a possible error:
Table 3.4 Status of the initialization procedure:
Error Solution
Undetermined bad Check air-pressure at the ac-
repeatability tuator and/or actuator sizing.
Running,
Aborted Operator: restart
Undetermined Difference between open
and close position too small.
Check proper stroking of the
actuator/valve unit.
Time Out It takes too long before end-
positions are found. Check
air-pressure at the actuator
and/or actuator sizing.
Range Error Difference between open and
closed end position is too
small. Check air-pressure,
check proper valve rotation.
No Valid Data Not initialized, start initializa-
tion
Assembly error The configuration of the mod-
ule and actuator do not match
and is incorrect. Check the
actuator and module function
for matching configurations.

To solve this:
1 Check table 3.4 and try the suggested solution to
solve the problem.
2 Check Actuator assembly code (see Installation &
Operation Manual Bettis Q-Series Valve Actuator,
DOC.IOM.BQ.E)
3 Repeat the initialization (calibration) procedure
(see §3.2).
4 When the actuator does not move within 10 sec-
onds, the auto initialization (calibration) will fail.
To solve this either;
- Perform the "default setting" procedure (see
- Set the limit switch points individually by the
3.4.3
1 Go to Configure/Manual Setup/Switch Points/
Change Switch Points
2 To set the "Open" position;
Set sub parameter OPEN_END_POSITION of
parameter CFG_SWITCH_POINTS to:
"set to current position".
The "Closed" position will change automatically.
3 To set the "Closed" position;
Set sub parameter OPEN_END_POSITION of
parameter CFG_SWITCH_POINTS to:
"set to current position".
The "Open" position will change automatically.
Note:
- If "Shutdown" is activated (see 4.2.3.3), check if
"SHUTDOWN_ACTION" matches with new posi-
tion feedback setting.
