Installation and Operating Instructions

6.3 Setting the stop level

If you are using the same level for start and stop,
remember to set a stop delay. It will prevent the pump
from starting and stopping too frequently.

6.5 Stop delay
The stop delay is the time from when the stop level is
reached until the pump stops. The stop delay
prevents the pump from starting and stopping too
frequently and reduces water hammer in long pipes.
6.5.1 Setting the stop delay with Grundfos GO
Remote
1. Select Settings > Level control > Stop delay >
State
2. Select Stop delay time.
3. Set the Stop delay time.
6.6 Power-on delay
With this function it is possible to delay the startup of
the pump after the power supply has been switched
on. The purpose is to avoid disturbing the main power
network which could happen if several pumps start up
immediately when the power supply is switched on.
6.6.1 Setting the power-on delay with Grundfos
GO Remote
1. Go to Settings > Power-on delay.
2. Set the function to Enabled.
3. Set the time delay.
6.7 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.
6.7.1 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
pump type. See the installation and
operating instructions for the product.
