3. General description
Grundfos MGE 71, MGE 80 and MGE 90 are
frequency-controlled permanent-magnet motors for single-phase
or three-phase mains connection. The motors incorporate a PI
controller.
The motors can be connected to a signal from an external sensor
and a setpoint signal enabling control in closed loop. The motors
can also be used for an open-loop system in which the setpoint
signal is used as a speed control signal.
The motors are only intended for machines with a square torque
characteristic, such as ventilators and centrifugal pumps.
The motors incorporate a control panel which is available in
various versions. See section 8. User interfaces for further
information.
Detailed motor settings are made with the wireless Grundfos
R100 remote control or Grundfos GO Remote.
Furthermore, important operating parameters can be read via the
R100 or Grundfos GO Remote.
The motors incorporate a functional module. The functional
module is available in various versions with different inputs and
outputs. See section 6.5 Functional modules for further
information.
As an accessory option, the motors can be fitted with a Grundfos
CIM module. A CIM module is an add-on communication interface
module. The CIM module enables data transmission between the
motor and an external system, for example a BMS or SCADA
system. The CIM module communicates via fieldbus protocols.
3.1 Radio communication
This product incorporates a radio module for remote control
which is a class 1 device and can be used anywhere in the EU
member states without restrictions.
For use in USA and Canada, see page 35.
This product can communicate with the Grundfos GO Remote
and other MGE motors of the same type via the built-in radio
module.
In some cases, an external antenna may be required.
Only Grundfos-approved external antennas may be connected to
this product, and only by a Grundfos-approved installer.
3.2 Battery
A Li-ion battery is fitted in the FM 300 functional module.
The Li-ion battery of the FM 300 module complies with the
Battery Directive (2006/66/EC). The battery does not contain
mercury, lead and cadmium.
Note
Some variants of this product and products sold
in China and Korea have no radio module.
