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.
R
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.

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.
