8.3.11 Confirming relubrication/replacement of motor
bearings (only three-phase pumps)
This function can be set to these values:
• Relubricated (only 11-22 kW)
• Replaced
• Nothing done.
When the bearing monitoring function is Active, the controller will
give a warning indication when the motor bearings are due to be
relubricated or replaced. See section
When the motor bearings have been relubricated or replaced,
confirm this action in the above display by pressing [OK].
Relubricated cannot be selected for a period of time
Note
after confirming relubrication.

8.3.12 Standstill heating (only three-phase pumps)

The standstill heating function can be set to these values:
• Active
• Not active.
When the function is set to Active, a low voltage will be applied to
the motor windings when the pump is not operating. The applied
voltage will ensure that sufficient heat is generated to avoid
condensation in the motor.

9. Setting by means of PC Tool E-products

Special setup requirements differing from the settings available
via the R100 require the use of Grundfos PC Tool E-products.
This again requires the assistance of a Grundfos service
technician or engineer. Contact your local Grundfos company for
more information.

10. Priority of settings

The priority of settings depends on two factors:
1. control source
2. settings.
1. Control source
Control panel
R100
External signals
(external setpoint signal, digital inputs, etc.)
Communication from another control system via
bus
2. Settings
• Operating mode Stop
• Operating mode Max. (max. curve)
• Operating mode Min. (min. curve)
• Setpoint setting.
An E-pump can be controlled by different control sources at the
same time, and each of these sources can be set differently.
Consequently, it is necessary to set an order of priority of the
control sources and the settings.
If two or more settings are activated at the same
Note time, the pump will operate according to the function
with the highest priority.
