7. Setting the pump
All control of the twin-head pump is carried out by
the master pump except when the pump is running
single-pump operation.
The slave pump will not respond to commands
(unless when in single-pump operation) from the
control panel, the R100 nor from external signal
transmitters but only to commands from the master
pump. All setting and reading of data must therefore
be done via the master pump.
The green slave pump indicator light will flash on and
off 20 times per minute to indicate correct communi-
cation between master and slave pump.
For the setting of the pump, use:
• Control panel.
• R100 remote control.
• Bus communication (not described in detail in
these instructions. Contact Grundfos).
The following table shows the application of the indi-
vidual operating units and in which section the func-
tion has been described.
"–" = not available with this operating unit.
7.1 Factory settings
7.2 Control panel
Note: Only the control panel of the master pump is
active unless the pump is running single-pump oper-
ation.
The control panel, fig. 13, incorporates the following:
• Buttons, "+" and "–", for setting.
• Light fields, yellow, for indication of control mode
and pump head.
• Indicator lights, green and red, for operating and
fault indication, see section 6.7 Indicator lights.

7.2.1 Setting of control mode
Description of function, see section 6.2 Control
modes.
When the buttons "+" and "–" are pressed simultane-
ously, the light fields will indicate the selected control
mode:
If the buttons are pressed for more than 5 sec., the
control mode will change over to constant pressure
and proportional pressure respectively. This means
that constant curve duty is deactivated if selected by
means of the R100.
