Grundfos CUE
30
Copy of Settings
The Grundfos Local Control Panel (GLCP) can be used
to copy the settings made on one CUE to another CUE.
The function includes two different possibilities:
• Make a copy of the setup from the present CUE to
t
he Grundfos Local Control Panel
• Make a copy of the setup stored in the Grundfos Lo-
cal Control Panel to the CUE
Both functions must be used in the correct order to copy
a set
up from one CUE to another.
A setup can be used for more than once, when it is
loaded
into the Grundfos Local Control Panel.
The copy can only be performed between units of the
same size
and firmware version.
Pipe fill (PC Tool)
The pipe fill function is used for filling empty pipes with
water in a controlled manner. With pipe fill disabled the
speed will go to maximum speed when filling the pipes
in pressure controlled systems where pipes are empty
at start up, and when the pipes are filled the high speed
will give pressure spikes in the system, before the
speed is reduced properly to fit the actual need in the
application.
The pipe filling function can be used to avoid these
pressu
re spikes, by introducing a pipe filling sequence
before the system is turned into normal operation.
The pipe filling function can limit the speed of the pump
duri
ng fill mode operation; this will decrease the pres-
sure spikes at full pipes. A time limit or a filled pipe
pressu
re can be used to deactivate the pipe fill function
and turn the CUE into normal operation.
The following parameters are used in fill mode:
Pipe fill
• Activate or deactivate the function
Pipe fill speed
• The maximum speed used during pipe filling (hori-
zontal piping)
Pipe fill time
• The time it takes to fill the pipes, the CUE turns into
no
rmal operation when the pipe fill time has passed
Pipe fill rate
• If a vertical pipe system is being filled a pipe fill rate
in
scale of the used transmitter can be used to limit
the pipe filling rate Example: [0.3bar/sec] (vertical
piping)
Filled setpoint
• The setpoint where the pipe fill function is deacti-
vated and the CUE turns into normal operation.
