3.6 Testing the product

When you have made all the electrical installations and completed

the startup wizard, you can test the system.

For emptying applications:

• Fill the pit with water and check that the pump starts

automatically at the defined level.

• 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.

• Test the high-level function by stopping the pump manually and

continue to fill the pit with water. Check that the control unit

indicates an alarm when the defined level is reached. Set the

pump to Auto and observe that the pump starts and stops

when the stop level has been 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 pump or two pumps.

The product can be configured for two purposes: emptying a

wastewater pit or filling a pit or tank. The product can be used for

network pumping stations, main pumping stations, commercial

buildings and municipal systems.

The control unit is only intended for use in control panels.

The product must not be exposed to aggressive solvents or oil-

containing liquids.

4.3 Features

The control unit features among others the following functions:

• manual and automatic control of the pump

• Bluetooth pairing with Grundfos GO Remote

• operating indication, such as power on and pump running

• alarm and warning indication, such as power phase missing

and high-water level

• motor and phase failure protection

• setting of stop delays matching the actual operating conditions

4.4 Application types

You can choose between two application types:

• Empty

• Fill.

You can set the application type with Grundfos GO Remote.

Description

1 High level

2 Not in use

3 Start level P1: start level for pump 1

4 Stop level

5 Dry-running level

The pump will start to empty the tank or pit when Start level P1 is

reached.

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 pit will rise. Eventually, the High level sensor will

register a high liquid level in the tank or pit. If set, the 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 pit falls

below the dry-running level, the dry-running protection will stop the

pump to ensure that it is not damaged mechanically.

5 Dry-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 will start to fill the second tank when Start level P1 is

reached.

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 will eventually

register 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 will stop the pump to

ensure that it is not damaged.

6.9 Dry-running protection

If the pump is running and the liquid level in the tank or pit becomes

lower than the dry-running level, the dry-running protection will stop

the pump to ensure that it is not damaged.

Dry-running protection is dependent on a feedback signal from a

level sensor installed in the tank or pit.

6.9.1

Setting the dry-running level with Grundfos GO Remote

1. Go to Settings > Level control > Dry-running level.

2. Set the dry-running level.

The dry-running level must be set to a value which

ensures that the pump is not damaged due to dry-

running. The specific level depends on the installed

6.11

Antiseizing

The Anti-seizing function prevents a pump from choking or seizing

up as a result of deposits buildup. Anti-seizing is used in pits that

have had no inlet flow for a long period. The Anti-seizing function

11

English (GB)

ensures that the pump starts as often as set in Anti-seizing > >

Interval. The pump will operate for the number of seconds

indicated by the user.

Remote

1. Go to Settings > Anti-seizing.

2. Set the function to Enabled.

3. Set the time interval.

4. Set the operating time.

6.12 Signal-detection time

The signal-detection time is the minimum time a level has to be

active before the control unit initiates an action, such as starting or

stopping a pump.

6.12.1 Setting the signal-detection time with Grundfos GO

Remote

1. Go to

Settings > Level control > Signal detection time.

2. Set the signal-detection time.

6.13 Setting the maximum number of restarts with

Grundfos GO Remote

If the pump is seized up as a result of deposits buildup, it will be

stopped automatically due to overheating, provided that the motor

protection has been set. When the motor has cooled down, the

control unit will unsuccessfully try to restart the pump and this

scenario will be repeated.

In order to prevent this, it is possible to set a maximum number of

restart attempts within a set interval.

1. Go to Settings > Max number of restarts.

2. Enable the function.

3. Set the interval within which the allowed number of restarts are

to be counted.

6.15 Motor protection

6.15.1

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

9.10 Code 69 (Winding temperature too high)

6.15.2

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

9.8 Code 48 (Motor is overloaded)

6.15.3 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.
