3. General description
Grundfos E-pumps have standard motors with integrated
frequency converter. The pumps are for single-phase or three-
phase mains connection.
The pumps have a built-in PI controller and can be set up for an
external sensor enabling control of the following parameters:
•pressure
• differential pressure
•temperature
• differential temperature
•flow.
From factory, the pumps have been set to control mode
uncontrolled. The PI controller can be activated by means of
R100.
The pumps are typically used as circulator pumps in large heating
or cooling water systems with variable demands.
3.1 Settings
The desired setpoint, can be set in three different ways:
• directly on the pump control panel
• via an input for external setpoint signal
• by means of the Grundfos wireless remote control R100.
All other settings are made by means of the R100.
Important parameters such as actual value of control parameter,
power consumption, etc. can be read via the R100.
3.2 Twin-head pumps
Twin-head pumps do not require any external controller.

When the pump is switched on via the mains, it will start after
approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for
external start/stop when starting/stopping the pump.
When the pump is switched on via an external on/off switch, it will
start immediately.
5.2.9 Connections
As a precaution, the wires to be connected to the following
connection groups must be separated from each other by
reinforced insulation in their entire lengths:
Group 1: Inputs
• start/stop, terminals 2 and 3
• digital input, terminals 1 and 9
• setpoint input, terminals 4, 5 and 6
• sensor input, terminals 7 and 8
• GENIbus, terminals B, Y and A
All inputs (group 1) are internally separated from the mains-
conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied with protective extra-low voltage
(PELV), thus ensuring protection against electric shock.
Group 2: Output (relay signal, terminals NC, C, NO)
The output (group 2) is galvanically separated from other circuits.
Therefore, the supply voltage or protective extra-low voltage can
be connected to the output as desired.
Group 3: Mains supply (terminals N, PE, L)
Group 4: Communication cable (8-pin male socket) - only
TPED
The communication cable is connected to the socket in group 4.

5.4.1 Preparation
Before connecting the E-pump to the mains, take the issues
illustrated in the figure below into consideration.
Fig. 10 Mains-connected pump with mains switch, backup
fuses, additional protection and protective earthing
5.4.2 Protection against electric shock - indirect contact
EN 61800-5-1 specifies that the pump must be stationary and
installed permanently when the leakage current is greater than 10
mA.
One of the following requirements must be fulfilled:
• A single protective earth conductor having a cross-sectional
area of min. 10 mm2copper.
Fig. 11 Connection of a single protective earth conductor
using one of the conductors of a 4-core mains cable
(with cross-sectional area of min. 10 mm2)
• Two protective earth conductors of the same cross-sectional
area as the mains conductors, with one conductor connected
to an additional earth terminal in the terminal box.
Fig. 12 Connection of two protective earth conductors using
two of the conductors of a 5-core mains cable
Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.
5.4.3 Backup fuses
For recommended fuse sizes, see section 21.1 Supply voltage.
5.4.4 Additional protection
If the pump is connected to an electric installation where an earth
leakage circuit breaker (ELCB) is used as additional protection,
the circuit breaker must be of a type marked with the following
symbols:
This circuit breaker is type B.
The total leakage current of all the electrical equipment in the
installation must be taken into account.
The leakage current of the motor in normal operation can be seen
in section 21.3 Leakage current.
During start and at asymmetrical supply systems, the leakage
current can be higher than normal and may cause the ELCB to
trip.
5.4.5 Motor protection
The pump requires no external motor protection. The motor
incorporates thermal protection against slow overloading and
blocking (IEC 34-11, TP 211).
5.4.6 Protection against mains voltage transients
The pump is protected against mains voltage transients in
accordance with EN 61800-3 and is capable of withstanding a
VDE 0160 pulse.
The pump has a replaceable varistor which is part of the transient
protection.
Over time this varistor will be worn and need to be replaced.
When the time for replacement has come, R100 and PC Tool E-
products will indicate this as a warning. See section
18. Maintenance and service.
5.4.7 Supply voltage and mains
3 x 380-480 V - 10 %/+ 10 %, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump
nameplate. Make sure that the motor is suitable for the power
supply of the installation site.
The wires in the terminal box must be as short as possible.
Excepted from this is the protective earth conductor which must
be so long that it is the last one to be disconnected in case the
cable is inadvertently pulled out of the cable entry.
Fig. 13 Mains connection
TM00 9270 4696
Warning
The pump must be earthed in accordance with local
regulations.
As the leakage current of 11-22 kW motors is greater
than 10 mA, take extra precautions when earthing
these motors.

5.4.8 Start/stop of pump
When the pump is switched on via the mains, it will start after
approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for
external start/stop when starting/stopping the pump.
When the pump is switched on via an external on/off switch, it will
start immediately.
5.4.9 Connections
As a precaution, the wires to be connected to the following
connection groups must be separated from each other by
reinforced insulation in their entire lengths:
Group 1: Inputs
• start/stop, terminals 2 and 3
• digital input, terminals 1 and 9
• setpoint input, terminals 4, 5 and 6
• sensor input, terminals 7 and 8
• GENIbus, terminals B, Y and A
All inputs (group 1) are internally separated from the mains-
conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied with protective extra-low voltage
(PELV), thus ensuring protection against electric shock.
Group 2: Output (relay signal, terminals NC, C, NO)
The output (group 2) is galvanically separated from other circuits.
Therefore, the supply voltage or protective extra-low voltage can
be connected to the output as desired.
Group 3: Mains supply (terminals L1, L2, L3)

The communication cable has a master end and a slave end as
shown in fig. 20.
Fig. 20 Master end and slave end
On pumps with factory-fitted sensor, the master end and the
sensor are connected to the same terminal box.
When the power supply to the two pumps has been switched off
for 40 seconds and switched on again, the pump connected to the
master end will start up first.
5.7.1 Connection of two sensors
The sensor signal is copied to the other pump through the red
wire of the communication cable.
If, optionally, two sensors are connected (one sensor to each
terminal box), cut the red wire. See fig. 21.
Fig. 21 Elimination of copied sensor signal
5.7.2 Elimination of alternating operation and standby
operation
If alternating operation and standby operation are not desired, but
the copied sensor signal (one sensor signal to two pumps) is
desired, cut the green wire. See fig. 22.
Fig. 22 Elimination of alternating operation and standby
operation
5.7.3 Elimination of TPED function
If alternating operation and standby operation as well as the
copied sensor signal are not desired, remove the communication
cable completely.
6. Modes
Grundfos E-pumps are set and controlled according to operating
and control modes.
6.1 Overview of modes
1) In this example the pump is equipped with a differential
pressure sensor. The pump may also be equipped with e.g. a
temperature sensor in which case the description would be
constant temperature in control mode controlled.
6.2 Operating mode
When the operating mode is set to Normal, the control mode can
be set to controlled or uncontrolled. See section 6.3 Control
mode.
The other operating modes that can be selected are Stop, Min. or
Max.
• Stop: The pump has been stopped.
• Min.: The pump is operating at its minimum speed.
• Max.: The pump is operating at its maximum speed.
Figure 23 is a schematic illustration of min. and max. curves.
Fig. 23 Min. and max. curves
The max. curve can for instance be used in connection with the
venting procedure during installation.
The min. curve can be used in periods in which a minimum flow is
required.
If the power supply to the pump is disconnected, the mode setting
will be stored.
The remote control R100 offers additional possibilities of setting
and status displays. See section 8. Setting by means of R100.

6.2.1 Additional operating modes - TPED pumps
The TPED pumps offer the following additional operating modes:
• Alternating operation
Pump operation alternates every 24 hours. If the duty pump
stops due to a fault, the other pump will start.
• Standby operation
One pump is operating continuously. In order to prevent
seizing-up, the other pump is started 10 sec. every 24 hours. If
the duty pump stops due to a fault, the other pump will start.
Select the operating mode by means of the selector switch in the
terminal box. See figs 5, 9and 15.
The selector switch enables changeover between the operating
modes "alternating operation" (left position) and "standby
operation" (right position).
The switches in the two terminal boxes must be set to the same
position. If the switches are positioned differently, the pump will
be in standby operation.
Twin-head pumps can be set and operated in the same way as
single-head pumps. The duty pump uses its setpoint setting,
whether it is made by means of the control panel, via the R100 or
via bus.
If the power supply to the pump is disconnected, the pump setting
will be stored.
The remote control R100 offers additional possibilities of setting
and status displays. See section 8. Setting by means of R100.
6.3 Control mode
The pump can be set to two control modes, i.e.
• controlled
• uncontrolled.
In control mode controlled, the pump will adjust its performance
to the desired setpoint for the control parameter (pressure,
differential pressure, temperature, differential temperature or
flow).
In control mode uncontrolled, the pump will operate according to
the constant curve set.
Fig. 24 Pump in control mode controlled (differential pressure
control) and in control mode uncontrolled
The pumps have been factory-set to control mode uncontrolled.
See section 6.4 Factory setting.
6.4 Factory setting
TPE, NKE, NKGE and NBE, NBGE pumps
The pumps have been factory-set to uncontrolled operation.
The setpoint value corresponds to 100 % of the maximum pump

8. Setting by means of R100
The pump is designed for wireless communication with the
Grundfos remote control R100.
Fig. 31 R100 communicating with the pump via infra-red light
During communication, the R100 must be pointed at the control
panel. When the R100 communicates with the pump, the red
indicator light will flash rapidly. Keep pointing the R100 at the
control panel until the red LED diode stops flashing.
The R100 offers setting and status displays for the pump.

8.1 Menu OPERATION
The first display in the menu is this.
8.1.1 Setpoint
Setpoint set
Actual setpoint
Actual value
Set the desired setpoint in this display.
In control mode controlled, the setting range is equal to the
sensor measuring range, e.g. 0 to 25 m.
In control mode uncontrolled, the setpoint is set in % of the
maximum performance. The setting range will lie between the
min. and max. curves.
If the pump is connected to an external setpoint signal, the value
in this display will be the maximum value of the external setpoint
signal. See section 12. External setpoint signal.
Setpoint and external signal
The setpoint cannot be set if the pump is controlled via external
signals (Stop, Min. curve or Max. curve). The R100 will give this
warning: External control!
Check if the pump is stopped via terminals 2-3 (open circuit) or
set to min. or max. via terminals 1-3 (closed circuit).
See section 10. Priority of settings.
Setpoint and bus communication
The setpoint cannot be set either if the pump is controlled from an
external control system via bus communication. The R100 will
give this warning: Bus control!
To override bus communication, disconnect the bus connection.
See section 10. Priority of settings.
8.1.2 Operating mode
Set one of the following operating modes:
•Max.
•Normal (duty)
•Min.
• Stop.
The operating modes can be set without changing the setpoint
setting.
8.1.3 Fault indications
In E-pumps, faults may result in two types of indication: alarm or
warning.
An alarm fault will activate an alarm indication in the R100 and
cause the pump to change operating mode, typically to stop.
However, for some faults resulting in alarm, the pump is set to
continue operating even if there is an alarm.
A warning fault will activate a warning indication in the R100, but
the pump will not change operating or control mode.
Alarm
In case of alarm, the cause will appear in this display.
Possible causes:
• No alarm indication
• Too high motor temperature
• Undervoltage
• Mains voltage asymmetry (11-22 kW)
• Overvoltage
• Too many restarts (after faults)
• Overload
• Underload (11-22 kW)
• Sensor signal outside signal range
• Setpoint signal outside signal range
• External fault
• Other fault.
If the pump has been set up to manual restart, an alarm indication
can be reset in this display if the cause of the fault has
disappeared.
Note
The indication "Warning" only applies to three-phase
pumps.

English (GB)
19
Warning (only three-phase pumps)
In case of warning, the cause will appear in this display.
Possible causes:
• No warning indication
• Sensor signal outside signal range
• Relubricate motor bearings (only 11-22 kW), see section
18.2 Relubrication of motor bearings
• Replace motor bearings. See section 18.3 Replacement of
motor bearings
• Replace varistor (only 11-22 kW), see section
18.4 Replacement of varistor (only 11-22 kW).
A warning indication will disappear automatically once the fault
has been remedied.
8.1.4 Fault log
For both fault types, alarm and warning, the R100 has a log
function.
Alarm log
In case of alarm faults, the last five alarm indications will appear
in the alarm log. "Alarm log 1" shows the latest fault, "Alarm log 2"
shows the latest fault but one, etc.
The example above gives this information:
• the alarm indication Undervoltage
• the fault code (73)
• the number of minutes the pump has been connected to the
power supply after the fault occurred, 8 min.
Warning log (only three-phase pumps)
In case of warning faults, the last five warning indications will
appear in the warning log. "Warning log 1" shows the latest fault,
"Warning log 2" shows the latest fault but one, etc.
The example above gives this information:
• the warning indication Relubricate motor bearings
• the fault code (240)
• the number of minutes the pump has been connected to the
power supply since the fault occurred, 30 min.
8.2 Menu STATUS
The displays appearing in this menu are status displays only. It is

8.2.7 Lubrication status of motor bearings (only 11-22 kW)
This display shows how many times the motor bearings have
been relubricated and when to replace the motor bearings.
When the motor bearings have been relubricated, confirm this
action in the INSTALLATION menu. See section
8.3.11 Confirming relubrication/replacement of motor bearings
(only three-phase pumps). When relubrication is confirmed, the
figure in the above display will be increased by one.
8.2.8 Time till relubrication of motor bearings (only 11-22 kW)
This display shows when to relubricate the motor bearings. The
controller monitors the operating pattern of the pump and
calculates the period between bearing relubrications. If the
operating pattern changes, the calculated time till relubrication
may change as well.
The displayable values are these:
• in 2 years
• in 1 year
• in 6 months
• in 3 months
• in 1 month
• in 1 week
•Now!
8.2.9 Time till replacement of motor bearings (only three-
phase pumps)
When the motor bearings have been relubricated, a prescribed
number of times stored in the controller, the display in section
8.2.8 Time till relubrication of motor bearings (only 11-22 kW) will
be replaced by the display below.
This display shows when to replace the motor bearings. The
controller monitors the operating pattern of the pump and
calculates the period between bearing replacements.
The displayable values are these:
• in 2 years
• in 1 year
• in 6 months
• in 3 months
• in 1 month

8.3.1 Control mode
Select one of the following control modes (see fig. 24):
• Controlled
•Uncontrolled.
How to set the desired performance, see section 8.1.1 Setpoint.
8.3.2 Controller
E-pumps have a factory default setting of gain (Kp) and integral
time (Ti). However, if the factory setting is not the optimum
setting, the gain and the integral time can be changed in the
display below.
• The gain (Kp) can be set within the range from 0.1 to 20.
• The integral time (Ti) can be set within the range from 0.1 to
3600 s. If 3600 s is selected, the controller will function as a P
controller.
• Furthermore, it is possible to set the controller to inverse
control, meaning that if the setpoint is increased, the speed
will be reduced. In the case of inverse control, the gain (Kp)
must be set within the range from -0.1 to -20.
Note
If the pump is connected to a bus, the control mode
cannot be selected via the R100. See section
13. Bus signal.
