Faults during commissioning

Table 20:
Faults during operation/commissioning
Fault
Mechanical position indicator cannot
be set.
In spite of correct setting of mechan-
ical limit switching, actuator operates
into the valve or actuator end position.
Actuator operation is too fast or too
slow.
Actuator suddenly stops in end posi-
tions.

SQRV 14.2 Control unit: electronic (MWG)
Description/cause
Reduction gearing is not suitable for actuator swing
angle.
The overrun was not considered when setting the
limit switching.
The overrun is generated by the inertia of both the
actuator and the valve and the delay time of the
actuator controls.
Operating time setting is incorrect.
Velocity reduction switched off or incorrectly set
before reaching end positions.
Faults interrupt or prevent the electrical actuator operation. In the event of a fault,
the display backlight is red.
Warnings have no influence on the electrical actuator operation. They only serve
for information purposes. The display remains white.
Collective signals include further indications. They can be displayed via the
Details push button. The display remains white.
Description/cause
Instead of the valve position, a status text is dis-
played.
Collective signal 02:
Indicates the number of active warnings.
Collective signal 04:
Indicates the number of active signals.
Collective signal 03:
Indicates the number of active faults.
The actuator cannot be operated.
Collective signal 07:
Indication according to NAMUR recommendation
NE 107
Actuator is operated outside the normal operation
conditions.
Corrective action
Remedy
Set gear stage of the reduction gearing.
The control unit might have to be exchanged.
Determine overrun: Overrun = travel covered
from switching off until complete standstill.
Set limit switching again considering the over-
run. (Turn handwheel back by the amount of
the overrun)
Modify operating time.
Modify velocity.
Remedy
For a description of the status texts, refer to Manual
(Operation and setting).
