6.9.1 Setting the multipump settings with Grundfos GO Remote
1. Go to Settings > Multi pump settings.
2. Set Inter pump delay.
This is the starting delay between the pumps ensuring that they
do not start at the same time.
3. Set Max number of running pumps.
This is the maximum number of pumps that are allowed to run at
the same time.
4. Set Max run time.
This is the maximum period of time the pump is allowed to run
before it stops.
5. Set Pump pause time.
This is how long the pump must remain paused before it starts
again.
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 Automatic test run
This function prevents a pump from choking or seizing up as a
result of deposits buildup. The function is used in pits that have had
no inlet flow for a long period. The function ensures that the pump
starts as often as set in Automatic test run > Interval. The pump
operates for the number of seconds set by the user.
6.11.1 Setting the automatic test run function with Grundfos
GO Remote
1. Go to Settings > Automatic test run.
2. Set the function to Enabled.
3. Set the time interval.
4. Set the operating time.
6.12 Setting the limit exceeded function
Use this function to monitor an IO terminal or one of the internal
values, such as power, current or result pulse flow.
If a set limit is reached, a selected action can take place. You can
set two limit exceeded functions, meaning that you can monitor two
parameters or two limits of the same parameter simultaneously.
1. Go to > Settings > Limit 1 exceeded or Limit 2 exceeded.
2. Follow on-screen instructions.
6.13 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.
6.13.1 Setting the signal-detection time with Grundfos GO
Remote
1. Go to Settings > Level control > Signal detection time.
2. Set the signal-detection time.
6.14 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.
4. Set the maximum number of pump restarts which are allowed
during the set interval.
