STATUS-NOT-SET | Setting-the-dry-running-level-with-Grundfos-GO-Remote-(ta)--RKTgTY.dita
5.8.1 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.
STATUS-NOT-SET | Setting-the-dry-running-level-with-the-operating-panel-(ta)--NwmwMs.dita
5.8.2 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.
STATUS-NOT-SET | Using-the-same-float-switch-for-the-start-and-stop-level-(ta)--QBdH3w.dita
5.9 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.
STATUS-NOT-SET | Multipump-settings-(co)-yqTZmrI.dita
5.10 "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.
STATUS-NOT-SET | Setting-multipump-settings-with-Grundfos-GO-Remote-(ta)--YyGSI4.dita
5.10.1 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.
STATUS-NOT-SET | Antiseizing-(co)-y6bB-8s.dita
5.11 "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.
STATUS-NOT-SET | Setting-the-Anti-seizing-function-with-Grundfos-GO-Remote-(ta)--Aj9ouE.dita
5.11.1 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.
STATUS-NOT-SET | Signal-detection-time-(co)-ywYVQsg.dita
5.12 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.
STATUS-NOT-SET | Setting-the-signal-detection-time-with-Grundfos-GO-Remote-(ta)--r4bS1s.dita
5.12.1 Setting the signal detection time with Grundfos GO
Remote
1. Go to Settings > Level control > Signal detection time.
2. Set the signal-detection time.
STATUS-NOT-SET | Setting-the-maximum-number-of-restarts-with-Grundfos-GO-Remote-(ta)--QrsAGY.dita
5.13 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.

STATUS-NOT-SET | Overheat-protection-(co)-yTqZohk.dita
5.14.1 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.

STATUS-NOT-SET | Overload-protection-(co)-ynryFSE.dita
5.14.2 Overload protection
The pump is protected by an external 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 lever. 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.

STATUS-NOT-SET | Moisture-protection-(co)-yNwmwMs.dita
5.14.3 Moisture protection
When a moisture sensor is installed in series with the thermal
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.
