The CIU unit is used as an interface for the following:
• Configuration of pump parameters required for
water level control.
• Online monitoring of pump pit and pump values.
• Manual water level control (forced start/stop).
• Obtaining of measured and logged data that is
very useful for pump service and pit optimisation.
The CIU unit is not used for water level

control in the pump pit.

3. Applications

The CIU unit is designed for use together with
Grundfos DP, EF, SL1, SLV and SEG AUTO
pumps.
Communication between the CIU unit and the pumps
can be established via the main network interface in
the CIU unit or with the Grundfos R100 remote
control.
The following CIU units are available:
• CIU 902 (without CIM module)
• CIU 202 Modbus unit
• CIU 252 GSM/GPRS unit
• CIU 272 GRM unit
(GRM = Grundfos Remote Management).
The CIU unit incorporates one or two modules:
• Multi-purpose IO module with I/O functionality,
IR communication interface and powerline
communication.
• CIM 2XX module (optional).
For further information about the CIM module fitted,
see installation and operating instructions for the
relevant CIM module.
If a CIM module is fitted in the CIU unit, sensors
connected to the digital input of the IO module can
be remotely monitored by a centrally located SCADA
system.
When the CIU unit is used, the internal
alarm relay in the pump should not be

used. The CIU unit takes over the alarm
function.
If the IO module is used in a manner not
specified by Grundfos, the protection

provided by the IO module may be
impaired.
