2.
Continuously press OK until the indicator light for the start level
for pump 1 starts flashing.
3.
Set the start level for pump 1 by using
the Up and Down buttons.
4.
Continuously press OK until the display stops flashing.
The settings have now been stored.
6.4 Setting the stop level
6.4.1 Setting the stop level with Grundfos GO Remote
The settings apply to analog sensors. For digital sensors, the
setting is automatically activated.
1.
Go to Settings > Level control > Stop level
2.
Set the stop level.
If you are using the same level for start and stop,
remember to set a stop delay. This will prevent the
pump from starting and stopping too frequently.
6.4.2 Setting the stop level with the operating panel
The settings apply to analog sensors. For digital sensors, the
setting is automatically activated.
1.
Press and hold OK until the display starts flashing.
2.
Press OK once.
The current stop level is indicated on the display.
3.
Set the stop level using the Up and Down buttons.
4.
Continuously press OK to confirm all other settings and to exit
the setup.
If you are using the same level for the start and stop
level, remember to set a stop delay. This will prevent
the pump from starting and stopping too frequently.
6.5 Setting the high level
6.5.1 Setting the high level with Grundfos GO Remote
For analog sensors:
1.
Go to Settings > Level control > High level.
2.
Set the high level.
For digital sensors:
1.
Go to > Settings > IO modules
2.
Select which terminal to configure.
6.5.2 Setting the high level with the operating panel
The settings apply to analog sensors
1.
Press and hold OK until the display starts flashing.
2.
Press OK four times. The current high level is indicated on the
display.
3.
Set the high level using the Up and Down button.
For digital sensors, enable or disable the setting.
1.
Press OK once to complete the setting.
6.6 After-run delay, high level
If the water level reaches the high level switch, due to either a
defective analog or digital level switch, the pump is only controlled
by the high level switch. To avoid too many starts and stops, an
after-run delay can be set which allows the pump to partly empty
the pit. The after-run delay should be set so that the pump stops at
the normal stop level to avoid dry running.
In case of an error, the product reports error 165 (Signal
fault) or error 205 (Level switch inconsistency) on the
display or in Grundfos GO Remote.
6.6.1 Setting the after-run delay, high level
1.
Go to Settings > Level control > After-run delay, high level.
2.
Select Enable or Disable.
3.
Set a delay time.
6.7 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.
6.7.1 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.
6.8 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.
6.8.1 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.
6.9 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
pump type. See the installation and operating
instructions for the product.
6.9.2 Setting the dry-running level with the operating panel
1.
Press and hold OK until the display starts flashing.
2.
Set the dry-running level using the Up or Down button.
3.
Continuously press OK to confirm all other settings and to exit
the setup.
6.10 Using the same level switch for the start and stop
level
1.
Set one digital input to Start pump 1 or Stop. All other digital
inputs must be disabled.
2.
Set a stop delay.
This will prevent the pump from starting and stopping too
frequently.
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
