Installation and Operating Instructions

6.7.2 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.
6.8 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.
6.9 "Multipump settings"
The control unit enables start and stop of the two
pumps alternately. The pump with the lowest number
of running hours is always started first. The function
ensures that the running hours of the pumps are the
same.
It is possible to set a time delay before the next pump
is started.
6.9.1 Setting "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 which are
allowed to run at the same time.
6.10 "Antiseizing"
The Antiseizing function prevents a pump from
choking or seizing up as a result of deposits buildup.
Antiseizing is used in pits that have had no inlet flow
for a long period. The Antiseizing function ensures
that the pump starts as often as set in Antiseizing >
interval. The pump will operate for the number of
seconds indicated by the user.
6.10.1 Setting the "Anti-seizing" function with
Grundfos GO Remote
1. Go to Settings > Anti-seizing.
2. Set the function to Enabled.
3. Set the time interval.
4. Set the operating time.
6.11 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.
6.11.1 Setting the signal detection time with
Grundfos GO Remote
1. Go to Settings > Level control > Signal
detection time.
2. Set the signal-detection time.
6.12 Setting the maximum number of
restarts with Grundfos GO Remote
If the pump is seized up as a result of deposits build-
up, 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.
