17.3.15 Priming and venting (10/16)
See the installation and operating instructions of the pump.
The general setting of the CUE is now completed, and the start-
up guide is ready for setting the direction of rotation:
•
Press OK to go on to automatic or manual setting of the
direction of rotation.
17.3.16 Automatic setting of the direction of rotation (11/16)
The CUE automatically tests and sets the correct direction of
rotation without changing the cable connections.
This test is not suitable for certain pump types and will in certain
cases not be able to determine for certainty the correct direction
of rotation. In these cases, the CUE changes over to manual
setting where the direction of rotation is determined on the basis
of the installer’s observations.
Information displays.
•
Press OK to continue.
The pump starts after 10 seconds.
It is possible to interrupt the test and return to the previous
display.
The pump runs with both directions of rotation and stops
automatically.
It is possible to interrupt the test, stop the pump and go to manual
setting of the direction of rotation.
17.3.17 Setpoint (15/16)
Set the setpoint according to the control mode and sensor
selected.
Warning
During the test, the pump will run for a short
time. Ensure no personnel or equipment is in
danger!
Note
Before setting the direction of rotation, the CUE
will make an automatic motor adaptation of
certain pump types. This will take a few minutes.
The adaptation is carried out during standstill.
The correct direction of
rotation has now been set.
• Press OK to set the
setpoint.
See
Setpoint (15/16)
on
page 26.
The automatic setting of the
direction of rotation has failed.
• Press OK to go to manual
setting of the direction of
rotation.
