3.6 Testing the product
When you have made all the electrical installations and completed
the startup wizard, you can test the system.
For dewatering applications:
• Ensure the pit is filled with water and check that the pump starts
automatically at the defined level.
• If possible, test the dry-running function by starting the pump
manually and wait while the pit with the pump is emptied. Check
that the control unit indicates an alarm and stops the pump
when the defined level is reached.
For filling applications:
• Start by draining the tank to be filled. When the tank is empty
and the start level is reached, the pump must start. When the
tank is full and the stop level is reached, the pump must stop.
• Test the high-level function by stopping the pump manually and
continue to fill the tank without the pump with water. Check that
the control unit indicates an alarm when the defined level is
reached.
• Test the dry-running function by starting the pump manually and
wait while the tank with the pump is emptied. Check that the
control unit indicates an alarm and stops the pump when the
defined level is reached. If the pump is placed in a well, this test
may not be possible since the pump cannot empty the well.
Alternatively, pull the dry-run level switch up to simulate a dry-
run situation. The same can be done with a pressure level
sensor.
4. Product introduction
4.1 Product description
The level-control unit switches the pump on and off according to the
liquid level measured by float switches or a pressure sensor. When
the start level is reached, the pump starts, and when the liquid level
has been lowered to the stop level, the pump is stopped by the
control unit. An alarm is indicated in case of for example high-water
level in the tank or sensor failure.
Basic settings are configured via the operating panel and advanced
settings are configured with Grundfos GO Remote. Furthermore,
you can read important operating parameters with Grundfos GO
Remote.
4.2 Intended use
The product is designed to control one or two pumps.
The product can be configured for the following two purposes:
• dewatering in groundwater supply
• filling a tank.
The product can be used for the following applications:
• groundwater supply
• irrigation systems
• small waterworks
• network pumping stations
• main pumping stations
• commercial buildings
• municipal systems.
The product must not be exposed to strong solvents or oil-
containing liquids.
4.3 Features

Pos. Description
1High level
2Start level P2: start level for pump 2
3Start level P1: start level for pump 1
4Stop level
5Dry-running level
The pump starts to empty the tank or well when Start level P1 is
reached.
A second pump starts when the liquid level reaches Start level P2.
The pump stops when the liquid level is lowered to Stop level.
If the inflow of liquid exceeds the capacity of the installed pump, the
level in the tank or well starts to rise. Eventually, the High level
sensor registers a high liquid level in the tank or well. If set, the
8
English (GB)

signal from the High level sensor can be used to activate an output
relay which can then be used to give a visual or acoustic alarm or
send a signal to a SCADA system.
If the pump is running and the liquid level in the tank or well falls
below the dry-running level, the dry-running protection stops the
pump to ensure that it is not damaged mechanically.

5Dry-running level
In the filling application, the pump is installed in a tank or well from
where it pumps the liquid. The liquid is pumped into a second tank
where the level sensors are installed.
The pump starts to fill the second tank when Start level P1 is
reached.
A second pump starts when the liquid level reaches Start level P2.
The pump stops when the liquid level reaches Stop level.
If the pump for some reason does not stop at Stop level and the
liquid level keeps rising, the High level sensor eventually
registers this. If set, the signal from the High level sensor can be
used to activate a relay output which can then be used to give a
visual or acoustic alarm or send a signal to a SCADA system via a
communication interface.
If the pump is running and the liquid level in the tank falls below the
dry-running level, the dry-running protection stops the pump to
ensure that it is not damaged.

6.17 Motor protection
Make sure that all settings are entered according to the
pump and system requirements to avoid malfunction.
6.17.1 Overheat protection
The control unit offers thermal protection for the connected motors.
Two types of thermal-protection sensor can be connected to the
control unit: a PTC sensor (analog) and a thermal switch (digital).
Under normal running conditions, the sensor will act as a short
circuit, but when its temperature limit is reached, it will open and tell
the control unit that the temperature is too high, and the pump is
stopped. When the temperature has dropped to the sensor-trigger
level, the pump will return to normal running conditions. It will not be
possible to start the pump manually as long as the temperature is
too high.
Related information
8.13 Code 69 (Winding temperature too high)
6.17.2 Overload protection
The pump is protected by a motor-protection relay. The nominal
current draw must be set manually on the motor-protection relay.
See the specific documentation for the relay on how to set the
trigger level. If the current exceeds the trigger level, the relay will
switch off the pump and the controller will give an alarm. The alarm
has to be manually reset directly on the motor protection relay.
Related information
8.11 Code 48 (Motor is overloaded)
6.17.3 Moisture protection
When a moisture sensor is installed in series with the temperature
sensor, the control unit needs to know how to determine whether
there is a high temperature or moisture in the pump. If the
temperature is too high, normally the temperature sensor will go
back to its normal stage when the temperature has dropped to its
trigger level. If there is moisture in the pump, then the moisture
sensor will keep the series connection open until the pump is
opened and serviced.
To determine which sensor has been active, a cool down
time must be entered. This is the time that will normally pass until
the temperature has dropped enough for the temperature sensor to
return to its normal stage. If the cool down time is exceeded, the
control unit will assume that there is moisture in the pump, and it
will send a moisture alarm.
