• Close the isolating valves, if fitted, and make sure that they
cannot be accidentally opened.

• Before starting work on the product, let the product and
pumped liquid cool off.

During assembly

• Lubricate and tighten screws and nuts according to
section 3. Torques and 4. Secondary materials.

After assembly

• If analog or digital inputs, the relay output or the CIM module
has been removed from the functional module, you must
check the communication with external units after service. See
section 7.14 Configuring the controller.

The installation and operating instructions for
this product and for the system which it is part of
must be available during service of the product.

Warnin g
Use personal protective equipment if there is a

risk of getting into contact with the pumped
liquid.

Observe local regulations.

Warnin g
Switch off the power supply and make sure that it

cannot be accidentally switched on. The power
supply must be switched off for at least five
minutes before you start working on the motor.

Check that other pumps or sources do not force
flow through the pump even if the pump is
stopped. This will cause the motor to act like a
generator, resulting in voltage on the terminals.

Caution

An installation with MGE motors must not be
megged as this may damage the built-in
electronic parts.

Motor windings may, however, be megged if the
terminal box has been removed.

Never measure between two terminals.

1. Disconnect the power supply.

2. Remove the terminal box.

See section 7.9 Replacing the terminal box.

3. Measure between terminals T1, T2, T3 and earth. As windings
are star-connected, fault in a winding will show when
measuring all terminals.

4. Replace the entire motor unit in case of fault.
See also measurement of winding resistances in section

8.4 Power module.

5. Fit the terminal box.
See section 7.9 Replacing the terminal box.

6. Switch on the power supply.

7. Start the pump.

7.14 Configuring the controller

Caution

English (GB)

The terminal box is configured from factory for the intended
application and pump type. The configuration file number appears
from the terminal box configuration label which is placed inside
the terminal box. See fig. 14.

Fig. 14 Position of configuration label

If the terminal box, functional module or power module is
replaced or mounted on another motor, it must be reconfigured.
Use PC Tool E-products for that purpose. To establish connection
to the motor, use Grundfos GO Remote MI 301 or PC Tool Link.

7.14.1 Connection to motor by means of Grundfos GO

Remote MI 301

Configuration can be done in three ways:

• Radio Scan

• Direct Connect

• IR Connect.

IR Connect

1. Switch on the power supply to the pump.

2. Connect the MI 301 to the PC.

3. Start the PC Tool. The first time the program is started, the
message "No COM port selected" will be shown. Click [OK].

Fig. 15 No COM port selected

4. Select "Preferences" in the main menu under "Files".

TM05 5967 4212

5. Open the dropdown menu "Select interface" and select
"MI 301". See fig. 16.

TM05 6928 0313TM05 7037 0413TM05 7132 0613TM05 6930 0313

If the power supply to the pump is interrupted
during configuration, the update will be lost.
This will, however, not damage the controller.
Start from the beginning.

Equipment

• PC Tool E-products, version 14.00.00 or newer

• MI 301 (PN 98046408) with USB cable.

Fig. 16 Selecting the user interface

6. Open the dropdown menu "Select port" and select the port
"PCTool-Link". See fig. 16. Click [Apply].

7. Point the MI 301 at the IR eye of the pump.
Distance: max. 20 cm. See fig. 17.

Fig. 17 IR connection via MI 301

8. Click [IR Connect]. See fig. 18. Wait while connection to the
pump is established (10-20 seconds).

Note

English (GB)

8.1 General information

1. Check the mains supply to the pump.

2. Read fault messages by means of Grundfos Eye,
Grundfos GO Remote, PC Tool or R100.

Make a copy of motor settings.

3. If possible, test if the motor can run without load. Remove the
coupling to the pump (if possible) and set the operating signal
to max. by means of PC Tool, Grundfos GO Remote or R100.

You can reset a fault indication in the following ways:

• When the fault cause has been eliminated and the pump is

switched on, the pump will revert to normal duty.

• If the fault disappears by itself, the fault indication will

automatically be reset.

The fault cause will be stored in the pump alarm or warning log.

Use a 100 Ω resistance and decide on the basis on the motor

Analog input, AI

It is possible to measure on the analog input to determine if its
function is correct.

During current state, a 292 Ω resistance in the input converts a
current signal (e.g. 0-20 mA) from the sensor to a voltage signal
for the processor.

Measure the voltage across the input and read the current in the
circuit by means of Grundfos GO Remote or PC Tool. The current
value must be equal to voltage divided with resistance.
Alternatively, a milliammeter can be connected in series with the
circuit.

Digital input, DI

See the settings of the input in PC Tool.
Connect the digital input to frame (GND) by means of an

ammeter. The value measured must now be approximately
12 mA. Check that PC Tool shows a corresponding value.

5 (+5 V) and the analog input. 5 V must now be read be means of
PC Tool.

within 20 seconds.

Change the setup of the input to current state and measure on
the input using an ohmmeter. The resistance must be 292 Ω.
In voltage state the resistance will be 122 kΩ.

Check if the relay reacts to the signals of the controller according

to the configuration of the controller.

Test the CIM module according to its manual.

Radio

If there are problems in the radio connection between
Grundfos GO Remote and the motor, remove the terminal box
cover. See section 7.1 Replacing the terminal box cover.
Replace the control panel if there is still no connection.
See section 7.4 Replacing the control panel.

Warning
The terminals of the power module are live.

Warning
Measuring equipment must be free of static

electricity or have same potential as the motor
before being used for measurement without
isolation cover.

If reading of fault codes does not provide a clear answer as to
whether the power module is functioning correctly, you can
proceed as described below.

1. Check that the voltage to the module is within the limit values
stated on the nameplate. Check all phases of a three-phase
motor.

2. If there are signs of moisture in the terminal box, take
necessary precautions to prevent similar faults.

3. Check the two status diodes of the power module
(the functional module must be connected) by looking under
the power module from the side. Status diode D54 must be
permanently on when connected to mains. Status diode D7
(three-phase model) or D19 (single-phase model) flashes
when the functionality is correct. See table below.

It may be necessary to dim the light as the diode
light is weak.

8.5 Winding resistance

As the motor is star-connected, the easiest way to measure the
winding resistance is to measure across two phases. Measure at
the coil temperatures stated in the table below. It may be
necessary to let the motor cool off if it has been running or if it
was stopped because of short-circuit or overload.
