7.10 External forced control
The pump incorporates inputs for external signals for
the forced-control functions:
•
start/stop of pump (terminals 1 and 2)
•
min. curve duty (terminals 3 and 4).
During forced control, the light fields or indicator
lights on the pump will show which function is active.
Functional diagram: Start/stop input
Functional diagram: Min. curve input
The min. curve input is only active if the start/stop
input is short-circuited.
7.11 Deactivating the control panel
To be set with the R100.
The buttons on the pump control panel can be
deactivated to prevent unauthorised persons from
operating the pump.
7.12 Bus communication
The pump has a serial communication port which
enables communication with the Grundfos Control
MPC Series 2000, a CIM/CIU communication
interface, a building management system or another
type of external control system.
If a CIU unit is installed in the system, it is possible to
establish communication between the pump and a
main network via one of the following protocols:
•
LON
•
Profibus DP
•
Modbus RTU
•
BACnet MS/TP.
For further details, see the installation and operating
instructions for the CIM and CIU.
Via the bus signal, it is possible to remote-set pump
operating parameters, such as desired head,
temperature influence and operating mode. At the
same time, the pump can provide status information
about important parameters, such as actual head,
actual flow, power input and fault indications.
The pump head and control mode can only be set via
the bus signal. The pump control panel or the R100
can only set the pump to max. curve and to stop.
However, an R100 is required if a number is to be
allocated to the pump. See sections
.
7.13 Remote control
The pump is designed for wireless communication
with the Grundfos R100 remote control. The R100
communicates with the pump via infrared light.
During communication, the R100 must be pointed
at the pump control panel. When the R100 is
communicating with the pump, the red indicator light
will flash rapidly.
The R100 offers additional setting options and status
displays for the pump. See section
.

Note
When the pump is controlled via a bus
signal, the number of settings available
on the pump control panel or via the
R100 will be reduced.
