13.2.3 Reuse of communication interface modules
You can reuse a communication interface module in a CIU unit
used together with Grundfos MAGNA Series 2000 in MAGNA3.
Before you use the CIM module in the pump, reconfigure the
module. Contact your nearest Grundfos company.

13.2.4 Auto detection of CIM modules
If a pump in a system with multiple pumps is replaced with a
newer version (model D), the new pump automatically detects if
the existing pump(s) and/or BMS system are older and adjusts
itself accordingly.
Auto detection in twin-head pumps happens if one of the pumps
is replaced and paired with a newer model than the existing one,
i.e. MAGNA3 model D. The new pump automatically detects the
model version of the existing pump. If the old pump is an older
model, the new pump will adjust itself making it compatible with
the old system.
Auto detection can be manually overruled if the system is
controlled by a SCADA system. However, when integrating a
newer model with an older setup, we recommend that you choose
compatibility mode.
For more information on how to manage auto detection directly
on the pump, see section "Multipump profile selection", page 50.
13.3 Counterflanges
Counterflange kits consist of two flanges, two gaskets and bolts
and nuts, making it possible to install the pump in any pipe. See
MAGNA3 data booklet, Accessories section, for the right
dimension and product number.
