Grundfos NBE Series - Product Settings and Control Modes; Basic Settings: Setpoint, Mode, Speed, and Control Modes

7. Setting the product
You can set control functions via Grundfos GO, Grundfos GO Link
or the HMI 300 or 301 operating panel.
• If only one function name is mentioned, it refers to both
Grundfos GO and the operating panel.
• If a function name is mentioned in a parenthesis, it refers to a
function on the operating panel.
7.1 Setpoint
Pump variant Setpoint
NBE, NKE, NBSE, VLSE ●
NBE, NKE, NBSE Series
2000; VLSE with Delta ρ sensor
●
When you have selected the desired control mode, set the setpoint.
7.2 Operating mode
Pump variant Operating mode
NBE, NKE, NBSE, VLSE ●

Possible operating modes
Normal
The product runs according to the selected control
mode.
Stop The product stops.
Min.
The product runs at minimum speed. You can use the
minimum curve mode in periods in which a minimum
flow is required. When operating according to the
minimum curve, the pump is operating like an
uncontrolled pump.
Max.
The product runs at maximum speed. You can use the
maximum curve mode in periods in which a maximum
flow is required. When operating according to the
maximum curve, the pump is operating like an
uncontrolled pump.
Manual
The product is operating at a manually set speed, and
the setpoint via bus and setpoint influence function are
overruled.
User-
defined
speed
The product is operating at a speed set by the user.

7.3 Set manual speed
Pump variant Set manual speed
NBE, NKE, NBSE, VLSE ●
NBE, NKE, NBSE Series
2000; VLSE with Delta ρ sensor
●
The function is only available in the HMI 300 and 301 operating
panels.
Use this function to set the speed in percentage of the maximum
speed. When you have set the operating mode to Manual, the
product starts running at the set speed.
With Grundfos GO, you can set the speed via the Setpoint menu.
7.4 Set user-defined speed
Use this function to set the motor speed in percentage of the
maximum speed. When you have set the operating mode to User-
defined speed, the motor starts running at the set speed.
7.5 Control mode
Pump variant Control mode
NBE, NKE, NBSE, VLSE ●
NBE, NKE, NBSE Series
2000; VLSE with Delta ρ sensor
●
You can choose between the following control modes:
• Prop. pressure (proportional pressure)
• Const. pressure (constant pressure)
• Const. temp. (constant temperature)
• Con. diff. press. (constant differential pressure)
• Con. diff. temp. (constant differential temperature)
• Const. flow rate (constant flow rate)
• Const. level (constant level)
• Const. other val. (constant other value)
• Const. curve (constant curve).
