2. Product introduction
2.1 Intended use
MP 204 is an electronic motor protector, designed for
the protection of an asynchronous motor or a pump.
It must always be installed in a cabinet.
MP 204 is designed for single- and three-phase
motors. In single-phase motors, the start and run
capacitors are also measured. Cos is measured in
both single- and three-phase systems.
MP 204 must only be installed according to the
technical specifications. See the installation and
operating instructions for the product.
2.2 Features
The motor protector consists of the following
components
a cabinet incorporating instrument transformers
and electronics.
an operating panel with operating buttons and
display for reading of data.
MP 204 operates with two sets of limits:
a set of warning limits
a set of trip limits.
If one or more of the warning limits are exceeded,
the motor continues to run, but the warnings will
appear in the MP 204 display.
If one of the trip limits is exceeded, the trip relay
stops the motor. At the same time, the signal relay is
operating to indicate that the limit has been
exceeded.
Some values only have a warning limit.
The warning can also be read by means of Grundfos
GO Remote.
2.3 Applications
MP 204 can be used as a stand-alone motor
protector.
MP 204 may also be incorporated in a Grundfos
Dedicated Controls system in which it functions as a
motor protector and data collection unit transmitting
measured values via Grundfos GENIbus to the
Grundfos CU 362 control unit.
Monitoring of MP 204 is possible via Grundfos
GENIbus.
The power supply to MP 204 is in parallel with the
supply to the motor. Motor currents up to 120 A are
passed directly through MP 204. MP 204 protects the
motor primarily by measuring the motor current by
means of a true RMS measurement. MP 204
disconnects the contactor if, for example, the current
exceeds the preset value.
The pump is protected secondarily by measuring the
temperature with a Tempcon sensor, a Pt100/Pt1000
sensor and a PTC sensor/thermal switch.

8.5 Wiring diagrams
8.5.1 Three-phase system
The wiring diagram, fig. 8, shows an example of a
three-phase pump with insulation measurement.
The connections to L1, L2, L3 and "5" can be made
with a cable of up to 10 mm
2
. A special fuse unit up
to approximately 50 A is therefore not required.
If larger backup fuses are used, the voltage to the
L1, L2 and L3 must be protected separately. We
recommend a maximum of 10 A or less.

9.2 Setting on operating panel
Press the and buttons simultaneously for a
minimum of 5 seconds to open the programming
mode. When the display shows three dots, the
buttons can be released.
The set value, e.g. "4.9 A", appears. The unit symbol
"A" is flashing.
Enter these values:
rated current
nominal voltage
trip class
number of phases.
Note: Insulation measurement is only possible of
earthed three-phase systems.
If no buttons are activated, the voltage appears after
10 seconds.
After an additional 10 seconds, the set voltage is
stored automatically, and the programming mode
ends. See fig. 16.
Note: Changes in rated current must be finished by
pressing to store the change.
9.2.1 Rated current
Set the rated motor current with the and
buttons. See the motor nameplate.
Press to store the setting and continue.
Press to cancel the change and finish.
The programming mode ends automatically after 10
seconds, and the change is cancelled. See fig. 16.
9.2.2 Nominal voltage
Set the nominal voltage with the and buttons.
Press to store the setting and continue.
Press to store the setting and finish.
The programming mode ends automatically after 10
seconds, and the change is stored. See fig. 16.
9.2.3 Trip class

For submersible pumps, manual setting of the trip
delay, class "P", is normally selected. The time is
factory-set to 10 seconds. It can be changed with
Grundfos GO Remote.
For other pumps, the required IEC trip class (1-45) is
to be set. Normally class 10 is selected. For trip
curves, see page 23.
Press to store the setting and continue.
Press to store the setting and finish.
The programming mode ends automatically after 10

9.3 Learning function
The learning function is factory-set to "Enabled".
After 2 minutes of continuous motor operation, "LRN"
appears on the display for approximately 5 seconds,
while the values are being stored in MP 204. See fig.
14, pos. 3.
If, for instance, a Pt sensor or capacitor has been
replaced, reactivate the learning function by pressing
the and buttons for a minimum of 10 seconds.
The dot in the right side of the display is flashing. MP
204 is waiting for current to pass through the unit for
a minimum of 120 seconds. Then the phase
sequence is measured and stored.
In single-phase systems, MP 204 measures the
capacity of the start and run capacitors and stores
the values as reference.
If a Pt100/Pt1000 sensor is installed, the cable
impedances to the sensor are measured and stored
as reference.
10. Grundfos GO Remote
The product is designed for infrared communication
with Grundfos GO Remote. MP 204 must be
configured using Grundfos GO Remote.
Grundfos GO Remote enables setting of functions
and gives access to status overviews, technical
product information, alarm logs and actual operating
parameters.
Fig. 17 Grundfos GO Remote communication
via infrared connection, IR
Grundfos MI 301
Separate module enabling radio or infrared
communication. Use the module together with an
Android or iOS-based smart device with Bluetooth
connection.
10.1 Infrared communication
When communicating via infrared light, Grundfos GO
Remote must be pointed at the operating panel.
10.2 Communication
If a Grundfos Communication Interface Unit (CIU) is
to be used, we recommend you to fit it according to
the wiring diagram and layout supplied with the
Control MP 204.
All variants can be extended with external
communication as an option.

11. MP 204 with GENIbus
If several MP 204 units are connected to the same
GENIbus, the connection is to be made as shown in
fig. 18.
Leave the screen as close to the conductive support
as possible.
If GENIbus has been in use, and bus communication
monitoring has been activated, MP 204 continues to
monitor the bus activity. If MP 204 does not receive
GENIbus telegrams, MP 204 presumes that the
GENIbus connection has been disconnected and
indicates a fault on the individual units.
Each of the units in the chain must be assigned an
identification number with Grundfos GO Remote.
For further information about GENIbus, see
Grundfos Product Center at www.grundfos.com.
Fig. 18 GENIbus
DANGER
Electric shock
Death or serious personal injury
- Ensure that the sensor and power
cables are separated when installing
GENIbus.
- Insulation between the cabinet and the
product must have a suitable insulation
resistance or the cabinet must be
connected to protective earth.
- All cables taken through the product
and the current transformers must be
insulated.
