14. Disposal 20

Before beginning installation procedures, these in­stallation and operating instructions should be stud­ied carefully. Furthermore, the enclosed installa-

tion and operating instructions for the standard
pump should be studied carefully. The installation

and operation should also be in accordance with lo­cal regulations and accepted codes of good practice.

1. General

GRUNDFOS E-pumps are pumps fitted with frequency-controlled
standard motors for single-phase or three-phase mains connec­tion.
The pumps have a built-in PI controller and can be connected to
an external sensor enabling control of for instance pressure, dif­ferential pressure, temperature, differential temperature or flow in
the system in which the pumps are installed. The pumps can be
set to uncontrolled operation, i.e. the pump performance can be
set according to the demand.

The pumps are typically used as circulator pumps in large heating
or cooling water systems with variable demands.

The desired value (setpoint), e.g. the desired differential pressure
if a differential pressure sensor has been installed, can be set di­rectly on the pump control panel, via an input for external setpoint
signal or 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.

The pump incorporates inputs for external potential-free contacts
for start/stop and digital function. The digital function enables ex­ternal setting of max. curve or min. curve.
The pump incorporates an output for a potential-free fault, operat­ing or ready signal.

Furthermore, the pump has an input for bus communication. Via
the bus communication input, the pump can be controlled and
monitored by a building management system or another external
control system.

1.1 Twin-head pumps

Single-phase twin-head pumps do not require any external con­troller.

Three-phase twin-head pumps usually require an external con­troller. The GRUNDFOS Delta Control 2000 ME has been devel­oped for this application.

For further details about the setting and connection of three­phase twin-head pumps, see installation and operating instruc­tions for the Delta Control 2000 ME.

2. Installation

To ensure cooling of motor and electronics, the following must be
observed:

• Place the pump in such a way that sufficient cooling is en­sured.

• The temperature of the cooling air must not exceed 40°C.

• Motor cooling fins and fan bl ades must be kept clean.

When installed outdoors, the motor must be provided with a suit­able cover to avoid condensation on the electronic components,
fig. 1.

For further installation, see installation and operating instructions
for the standard pump.

2.1 Electrical connection – single-phase pumps

Note: The user or the installer is responsible for the installation of

the correct earthing and protection according to valid national and
local standards. All operations must be carried out by a qualified
electrician.

Never make any connections in the pump terminal
box unless the electricity supply has been switched
off for at least 5 minutes.

2.1.1 Mains switch

The pump must be connected to an external all-pole mains switch
with a contact separation of at least 3 mm in each pole according
to IEC 364.

2.1.2 Protection against electric shock – indirect contact

The pump must be earthed and protected against
indirect contact in accordance with national regula­tions.

Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.

2.1.3 Additional protection

If the pump is connected to an electric installation where an earth
leakage circuit breaker is used as additional protection, this cir­cuit breaker must be marked with the following symbol:

Note: When an earth leakage circuit breaker is selected, the total
leakage current of all the electrical equipment in the installation
must be taken into account.

The leakage current of the pump can be found in section

12.2 Leakage current.

2.1.4 Motor protection

The pump requires no external motor protection. The motor incor­porates thermal protection against slow overloading and blocking
(IEC 34-11: TP 211).

2.1.5 Overvoltage protection

The pump is overvoltage-protected through built-in varistors be­tween phase-neutral and phase-earth.

2.1.6 Supply voltage

1 x 200-240 V ±10%, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump

nameplate. Please make sure that the motor is suitable for the
electricity supply on which it will be used.

The wires in the pump 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.

2.1.7 Start/stop of pump

The number of starts and stops via the mains voltage must not
exceed 4 times per hour.
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, the input for ex­ternal start/stop must be used when starting/stopping the pump.
When the pump is started/stopped via an external on/off switch, it
will start immediately.

2.2 Electrical connection – three-phase pumps

Note: The user or the installer is responsible for the installation of

the correct earthing and protection according to valid nation al and
local standards. All operations must be carried out by a qualified
electrician.

Never make any connections in the pump terminal
box unless the electricity supply has been switched
off for at least 5 minutes.

2.2.1 Mains switch

The pump must be connected to an external all-pole main s switch
with a contact separation of at least 3 mm in each pole according
to IEC 364.

2.2.2 Protection against electric shock – indirect contact

The pump must be earthed and protected against
indirect contact in accordance with national regula­tions.

Protective earth conductors must always have a yellow/green
(PE) or yellow/green/blue (PEN) colour marking.

Note: As the leakage current of 4 kW to 7.5 kW motors is
> 3.5 mA, these motors must be connected to especially
reliable/sturdy earth connections.

The leakage current of the individual motor size can be found in
section 13.2 Leakage current.

EN 50 178 and BS 7671 specify the following:

Leakage current > 3.5 mA:

The pump must be stationary and installed permanently. Further­more, the pump must be connected permanently to the electricity
supply or may be connected via an industrial type of plug (CEE).
The plug must comply with EN 60 309 or IEC 309.

• The earth connection must be carried out as duplicate conduc­tors.

2.2.3 Additional protection

If the pump is connected to an electric installation where an earth
leakage circuit breaker is used as additional protection, this cir­cuit breaker must be of the type:

• which is suitable for handling leakage currents and cutting-in
with short pulse-shaped leakage.

• which trips out when alternating fault currents and fault cur­rents with DC content, i.e. pulsating DC and smooth DC fault
currents, occur.

For these pumps an earth leakage circuit breaker type B m ust be
used.
This circuit breaker must be marked with the following symbols:

ELCB

2.2.6 Supply voltage

3 x 380-415 V ±10%, 50/60 Hz, PE.
The supply voltage and frequency are marked on the pump

nameplate. Please make sure that the motor is suitable for the
electricity supply on which it will be used.

The wires in the pump 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.

2.2.7 Start/stop of pump

The number of starts and stops via the mains voltage must not
exceed 4 times per hour.
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, the input for ex­ternal start/stop must be used when starting/stopping the pump.
When the pump is started/stopped via an external on/off switch , it
will start immediately.

2.3 Other connections – single-phase pumps

Note: For single-phase TPED pumps, see section 2.4 Other con-

nections – single-phase TPED pumps.
The connection terminals of external potential-free contacts for

start/stop and digital function, external setpoint signal, sensor sig­nal, GENIbus and relay signal are shown in fig. 8.

Note: If no external on/off switch is connected, short-circuit termi­nals 2 and 3 using a short wire.

Note: 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:

1. Inputs (external start/stop, digital function, setpoint and sen­sor signals, terminals 1-9, and bus connection, B, Y, A).

All inputs (group 1) are internally separated from the mains­conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied by protective extra-low volt­age (PELV), thus ensuring protection against electric shock.

2. Output (relay signal, terminals NC, C, NO).
The output (group 2) is galvanically separated from other cir-

cuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.

3. Supply voltage (terminals N, PE, L).

A galvanically safe separation must fulfil the requirements for re­inforced insulation including creepage distances and clearances
specified in EN 50 178.

2.4 Other connections – single-phase TPED pumps

The connection terminals of external potential-free contacts for
start/stop and digital function, external setpoint signal, sensor sig­nal, GENIbus, relay signal and communication cable are shown in
fig. 9.

Note: If no external on/off switch is connected, short-circuit termi­nals 2 and 3 using a short wire.

Note: 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:

1. Inputs (external start/stop, digital function, setpoint and sen­sor signals, terminals 1-9, and bus connection, B, Y, A).

cuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.

3. Supply voltage (terminals N, PE, L).

4. Communication cable (8-pin male socket).
The communication cable is connected to the socket in group

4. The cable ensures communication between the two pumps,
whether one or two pressure sensors are connected, see sec­tion 2.6 Signal cables.

The selector switch in group 4 enables changeover between
the operating modes “alternating operation” and “standby op­eration”. See description in section 3.2.1 Additional operating
modes – single-phase TPED pumps.

A galvanically safe separation must fulfil the requirements for re­inforced insulation including creepage distances and clearances
specified in EN 50 178.

The connection terminals of external potential-free contacts for
start/stop and digital function, external setpoint si gn al, sensor sig ­nal, GENIbus and relay signal are shown in figs. 10 and 11.

Note: If no external on/off switch is connected, short-circuit termi­nals 2 and 3 using a short wire.

Note: 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:

1. Inputs (external start/stop, digital function, setpoint and sen­sor signals, terminals 1-8, and bus connection, A, Y, B).

All inputs (group 1) are internally separated from the mains­conducting parts by reinforced insulation and galvanically
separated from other circuits.
All control terminals are supplied by protective extra-low volt­age (PELV), thus ensuring protection against electric shock.

2. Output (relay signal, terminals NC, NO, C).
The output (group 2) is galvanically separated from other cir-

cuits. Therefore, the supply voltage or protective extra-low
voltage can be connected to the output as desired.

3. Supply voltage (terminals L1, L2, L3).

A galvanically safe separation must fulfil the requirements for re­inforced insulation including creepage distances and clearances
specified in EN 50 178.

3. Setting the pump

3.1 Control modes

E-pumps can be set to two control modes, i.e:

• controlled-operation or

• uncontrolled-operation.
In controlled-operation mode, the pump will adjust its perform-

ance to the desired setpoint for the control parameter (pressure,
differential pressure, temperature, differential temperature or
flow). Figure 18 shows a differential-pressure controlled pump as
an example of controlled operation.

In uncontrolled-operation mode, the pump will operate accord­ing to the constant curve set.

If one sensor is connected, it is connected to t he master pu mp to
the left of the flow direction.

If two sensors are connected, one sensor is connected to the
master pump (to the left of the flow direction) and the other to the
slave pump, see fig. 17.

The pumps have been factory-set to uncontrolled operation, see
section 3.3 Factory setting.

3.2 Operating modes

The following operating modes can be selected:

•Stop,

•Min.,

TM02 6012 4702TM02 6013 4702TM02 6014 4702

• Normal (controlled or uncontrolled operation),

•Max.
The operating modes can all be set on the pump control panel.

Fig. 19

The min. curve can be used in periods in which a minimum flow is
required.

The max. curve can for instance be used in connection with the
venting procedure during installation.

If the electricity 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 5. Setting by means of R100.

3.2.1 Additional operating modes – single-phase TPED
pumps

The single-phase 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 st ops due to a fault, the other
pump will start.

The operating mode is selected by means of a selector switch in
each terminal box, see fig. 9.

H

The selector switches enable changeover between the operating
modes “alternating operation” (left position) and “standby oper-
ation” (right position).

The switches in the two terminal boxes must be set to the same
position. If the switches are positioned differently, “standby oper­ation” is selected.

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.

Note: Both pumps should be set to the same setpoint and control
mode. Different settings will result in different operation when
changing between the two pumps.

If the electricity 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 5. Setting by means of R100.

3.3 Factory setting

Note: For single-phase TPED pumps, see section 3.4 Factory

setting – single-phase TPED pumps.
The pumps have been factory-set to uncontrolled operation. The

setpoint value corresponds to 100% of the maximum pump per­formance (see data sheet for the pump).

Other pump settings are marked with bold-faced type under each
individual display in sections 5.1 Menu OPERATION and

5.3 Menu INSTALLATION.

3.4 Factory setting – single-phase TPED pumps

The pumps have been factory-set to uncontrolled operation and
the additional operating mode “alternating operation”.

The setpoint value corresponds to 100% of the maximum pump
performance (see data sheet for the pump).

Other pump settings are marked with bold-faced type under each
individual display in sections 5.1 Menu OPERATION and

5.3 Menu INSTALLATION.

4. Setting by means of control panel

At high system temperatures, the pump may be so
hot that only the buttons should be touched to avoid
burns.

The pump control panel, fig. 20, incorporates the following:

• Buttons, “+” and “–”, for setpoint setting.

• Light fields, yellow, for indication of setpoint.

• Indicator lights, green (operation) and red (fault).

5. Setting by means of R100

The pump is designed for wireless communication with the
GRUNDFOS remote control R100.

Fig. 25

Fig. 26

The R100 communicates with the pump via infra-red light. The
transmitter and the receiver are incorporated in the pump control
panel, fig. 25.

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.

The R100 offers additional possibilities of setting and status dis­plays for the pump.

The displays are divided into four parallel menus, fig. 26:

5.1 Menu

When communication between the R100 and the pump has been
established, the first display in this menu will appear.

5.1.1 Setpoint setting

In this display, the setpoint is set.
In controlled-operation mode, the setting range is equal to the

sensor measuring range, e.g. 0 to 25 m.
In uncontrolled-operation mode, the setpoint is set in % of the

maximum performance. The setting range will lie between the
min. and max. curves.

Select one of the following operating modes:

• Stop,

• Min. (min. curve),

• Max. (max. curve).
If the pump is connected to an external setpoint signal, the set-

point in this display will be the maximum value of the external set­point signal, see section 7. External setpoint signal.

If the pump is controlled via external signals (Stop, Min. curve or
Max. curve) or a bus, this will be indicated in the display if set­point setting is attempted.

In this case, the number of possible settings will be reduced, see
section 9. Priority of settings.

fault has disappeared.

5.1.4 Alarm log

If faults have been indicated, the last five fault indications will ap­pear in the alarm log. “Alarm log 1” shows the newest/latest fault.

The example shows the fault indication “Undervoltage”, the fault
code and the number of minutes the pump has been connected to
the electricity supply after the fault occurred.

The time cannot be displayed for three-phase pumps as the soft­ware does not support this function.

5.2 Menu STATUS

The displays appearing in this menu are status displays only. It is
not possible to change or set values.

The displayed values are the values that applied when the last
communication between the pump and the R100 took place. If a
status value is to be updated, point the R100 at the control panel
and press “OK”.
If a parameter, e.g. speed, should be called up continuously,
press “OK” constantly during the period in which the parameter in
question should be monitored.

The tolerance of the displayed value is stated under each display.
The tolerances are stated as a guide in % of the maximum values
of the parameters.

5.2.1 Display of actual setpoint

Select one of the following operating modes:

• Stop,

• Min.,

• Normal (duty),

• Max.
The operating modes can be selected without changing the set-

point setting.

5.1.3 Fault indications

If the pump is faulty, the cause will appear in this display.
Possible causes:

• Too high motor temperature

• Undervolta ge

• Overvoltage

• Phase failure (three-phase pumps only)

• Mains supply failure (three-phase pumps only)

• Too many restarts (after faults)

• Overload

• Sensor signal outside signal range (only 4-20 mA)

5.2.4 Display of actual speed

Tolerance: ±5%

The actual pump speed will appear in this display.

5.2.5 Display of input power and power consumption

Tolerance: ±10%

This display shows the actual pump input power from the mains
supply. The power is displayed in W or kW.

The pump power consumption can also be read from this display.
The value of power consumption is an accumulated value calcu­lated from the pump’s birth and it cannot be reset.

5.2.6 Display of operating hours

Furthermore, it is possible to set the controller to inverse control
(if the setpoint is increased, the speed will be reduced). In the
case of inverse control, the gain (K

) must be set within the range

p

from –0.1 to –20.

Setting the PI controller:

For most applications, the factory setting of the controller con­stants K

8. Bus signal

The pump enables serial communication via an RS-485 input.
The communication is carried out according to the GRUNDFOS
bus protocol, GENIbus protocol, and enables connection to a
building management system or another external control system.

Via the bus signal, it is possible to remote-set pump operating pa­rameters, like setpoint, operating mode, etc. At the same time,
the pump can provide status information about impo rtant parame­ters, like actual value of control parameter, input power, fault indi­cations, etc.

Contact GRUNDFOS for further details.
Note: If a bus signal is used, the number of settings available via

the R100 will be reduced.

TM00 7669 1696

9. Priority of settings

The start/stop and digital inputs will influence the number of pos­sible settings.

By means of the R100, the pump can always be se t to ma x. curve
duty or to stop.

If two or more functions are activated at the same time, the pump
will operate according to the function with the highest priority.

The priority of the settings is as shown in the following tables:
