2. General description

The GRUNDFOS MAGNA Series 2000 is a complete
range of circulator pumps with integrated differential
pressure control enabling adjustment of pump
performance to the actual system requirements.
In many systems, this will reduce the power
consumption considerably, reduce noise from
thermostatic valves and similar fittings, and improve
the control of the system.

The desired head can be set on the pump control
panel.

English (GB)

Warning
Prior to installation, read these

installation and operating instructions.
Installation and operation must comply
with local regulations and accepted
codes of good practice.

8

3. Applications

English (GB)

The GRUNDFOS MAGNA is designed for circulating
liquids in heating and air-conditioning systems. The
pump can also be used in domestic hot-water
systems.

The pump range is primarily used in

• systems with a variable flow.
The pump range can also be used in

• systems with a co nstant flow where it is
desirable to optimise the setting of the pump duty
point,

• systems with variable flow-pipe temperature.

3.1 Pumped liquids

Thin, clean, non-aggressive and non-explosive
liquids, not containing solid particles, fibres or
mineral oil.

In heating systems, the water should meet the
requirements of accepted standards on water quality
in heating systems, e.g. the German standard
VDI 2035.

In domestic hot-water systems, it is advisable to
use GRUNDFOS MAGNA pumps only for water with
a degree of hardness lower than approx. 14 °dH.

Warning
The pump must not be used for the

transfer of inflammable liquids such as
diesel oil, petrol or similar liquids.

4. Installation

Arrows on the pump housing indicate the liquid flow
direction through the pump.

4.1 Positioning

GRUNDFOS MAGNA must be installed with the
pump head in horizontal position. See page 13.

4.2 Changing the control box position

Warning
Before any dismantling of the pump,

the system must be drained or the
isolating valves on both sides of the
pump must be closed as the pumped
liquid may be scalding hot and under
high pressure.

4.3 Insulation shells

Note

Caution

Note

It is recommended to fit insulation
shells to the pump.

• Insulation shells for pumps in heating systems
are supplied with the pump.

• Insul a t io n sh e l l s f o r pu m ps i n air-conditioning sys­tems are accessories and must be ordered sepa­rately. Please contact Grundfos.

The fitting of insulation shells will increase the pump
dimensions. See the dotted line on the dimensional
sketches on pages 8 and 9.

The insulation shells are only available for single­head pumps.

4.4 Twin-head pumps

Twin-head pumps are supplied fitted with a GENI
module on each control box. The modules are
connected via a cable. The modules determine the
operating mode of the pump, see section

7.9.1 Control of twin-head pumps.

Twin-head pumps mounted in
horizontal pipes must be fitted with an
automatic air vent (Rp 1/4) in the upper
part of the pump housing, see fig. 1.

The automatic air vent is not supplied with the pump.

.

4.6 Frost protection

If the pump is not used during periods of frost,
necessary steps must be taken to prevent frost
bursts.

Additives with a density and/or
kinematic viscosity higher than those/
that of water will reduce the hydraulic
performance.

5. Electrical connection

The electrical connection and protection must be
carried out in accordance with local regulations.

Warning
The pump must be connected to an

external mains switch with a contact
separation of at least 3 mm in each
pole.

Earthing or neutralisation can be used
for protection against indirect contact.

Megging must be carried out as
described in section 10. Megging.

If the pump is connected to an electric
installation where an earth leakage
circuit breaker (ELCB) is used as
additional protection, this circuit
breaker must trip out when earth fault
currents with DC content (pulsating
DC) occur.
The earth leakage circuit breaker must
be marked with this symbol:

English (GB)

Fig. 1 Automatic air vent

4.5 Non-return valve

If a non-return valve is fitted in the pipe system, see
fig. 2, it must be ensured that the set minimum
discharge pressure of the pump is always higher
than the closing pressure of the valve. This is
especially important in proportional-pressure control
mode (reduced head at low flow).

Fig. 2 Non-return valve

• The pump requires no external motor protection.

7. Functions

Most functions can be selected on the pump control panel. However, some functions can only be selected with
the R100 or via expansion modules.

On the pump control panel, see fig. 11, page 18:

• AUTO

ADAPT (factory setting)

Recommended for most heating installations.
During operation, the pump automatically makes the necessary adjustment to the actual system
characteristic. This setting ensures minimum energy consumption and noise level which reduces
operating costs and increases comfort.

• Proportional-pressure control
The pump head is changed continuously in accordance with the water demand in the system. The desired
setpoint can be set on the pump control panel.

• Constant-pressure control
A constant head is maintained, irrespective of water demand. The desired setpoint can be set on the
pump control panel.

• Automatic night-time duty
The pump changes automatically between normal duty and night-time duty depending on the flow-pipe
temperature. Automatic night-time duty can be combined with the above-mentioned control modes.

Further functions:
With the R100 remote control:

• Constant-curve duty
The pump runs at a constant speed, on or between the max. and min. curves.

• Temperature influence
The pump head varies depending on the liquid temperature.

Via expansion modules:
GENI module

• External analog control of head or speed via a signal from an external 0-10 V sig nal transmitter.

• External forced control via inputs for:

- Max. curve

- Min. curve.

• Bus communication via GENIbus
The pump can be controlled and monitored by a Grundfos Control MPC Series 2000, a building
management system or another type of external control system.

• Control of twin -head pumps
The control of twin-head pumps is described in section 7.9.1.

• External start/stop
The pump can be started and stopped via the digital input.

• Fault, ready and operating indication via signal relay
The pump controls an external fault, ready and operating signal relay via a potential-free output.
The function of the signal relay is set with the R100.

7.3 Automatic night-time duty

To be set on the control panel or with the R100, see
section 8. Setting the pump .

Once automatic night-time duty has been activated,
the pump automatically changes between normal
duty and night-time duty (duty at low performance).

Changeover between normal duty and night-time
duty is dependent on the flow-pipe temperature.

The pump automatically changes over to night-time
duty when the built-in sensor registers a flow-pipe
temperature drop of more than 10-15 °C within
approx. 2 hours. The temperature drop must be at
least 0.1 °C/min.

Changeover to normal duty takes place without a
time lag when the temperature has increased by
approx. 10 °C.

Automatic night-time duty cannot be
used in air-conditioning systems.

7.5 Max. or min. curve duty

To be set on the control panel, with the R100 or via
GENI module, see section 8. Setting the pump.

The pump can be set to operate according to the
max. or min. curve, like an uncontrolled pump, see
fig. 6.

This operating mode is available, irrespective of the
control mode.

Fig. 6 Max. and min. curves

The max. curve mode can be selected if an
uncontrolled pump is required.

The min. curve mode can be used in periods in
which a minimum flow is required. This operating
mode is for instance suitable for manual night-time
duty if automatic night-time duty is not desired.

7.6 Temperature influence

To be set with the R100, see section 8. Setting the
pump.

When this function is activated in proportional- or
constant-pressure control mode, the setpoint for
head will be reduced according to the liquid
temperature.

It is possible to set temperature influence to function
at liquid temperatures below 80 °C or below 50 °C.
These temperature limits are called T
setpoint is reduced in relation to the head set
(= 100 %) according to the characteristics below.

Fig. 7 Temperature influence

In the above example, T
selected. The actual liquid temperature T
causes the setpoint for head to be reduced from

.

The temperature influence function requires:

• Proportional- or constant-pressure control mode.

TM03 0551 0205TM00 5547 4596

• The pump must be installed in the flow pipe.

• System with flow-pipe temperature control.
Temperature influence is suitable in:

• systems with variab le flo ws (e. g. tw o- pipe
heating systems), in which the activation of the
temperature influence function will ensure a
further reduction of the pump performance in
periods with small heating demands and
consequently a reduced flow-pipe temperature.

• systems with almost constant flows (e.g. one­pipe heating systems and underfloor heating
systems), in which variable heating demands
cannot be registered as changes in the head as
is the case with two-pipe heating systems. In
such systems, the pump performance can only
be adjusted by activating the temperature
influence function.

operation", which is described below.

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 will start at a
fixed frequency and run for a short period. If the
duty pump stops due to a fault, the other pump
will start.

In air-conditioning systems, standby
operation is recommended to avoid
critical condensation inside the pump.

Operating the pump

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 on the
control panel, with the R100 or via bus.

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.

2. Generel beskrivelse

GRUNDFOS MAGNA Serie 2000 er en komplet serie
af cirkulationspumper med integreret differenstryk­regulering hvorved pumpens ydelse tilpasses anlæg­gets aktuelle behov. Dette vil i mange anlægstyper
føre til en væsentlig energibesparelse, reduktion af
støj i ventiler og lign. samt forbedring af anlæggets
regulering.

Den ønskede løftehøjde kan indstilles direkte på
pumpens betjeningspanel.

3. Anvendelse

GRUNDFOS MAGNA er udviklet til cirkulation af
medier i varme- og airconditionanlæg. Pumpen kan
desuden bruges til cirkulation i brugsvandsanlæg.

Pumpeserien bruges primært i

• anlæg med variabelt flow.
Pumpeserien kan også bruges i

• anlæg med konstant flow hvor man ønsker at
kunne indstille pumpens driftspunkt optimalt,

• anlæg med variabel fremløbstemperatur.

3.1 Pumpemedier

Rene, tyndtflydende, ikke-aggressive og ikke-eksplo­sive medier uden indhold af faste bestanddele, fibre
eller mineralsk olie.

I varmeanlæg bør vandet opfylde kravene i gængse
normer for vandkvalitet i varmeanlæg, f.eks. den
tyske VDI 2035-norm.

I brugsvandsanlæg anbefales det kun at bruge
GRUNDFOS MAGNA pumper i vand med en hård­hedsgrad under ca. 14 °dH.

Advarsel
Pumpen må ikke bruges til transport af

brandfarlige væsker så som dieselolie,
benzin og lign.

4. Installation

Pilene på pumpehuset angiver mediets strømnings­retning gennem pumpen.

4.1 Placering af pumpen

GRUNDFOS MAGNA skal installeres med
pumpehovedet i horisontal position. Se side 13.

4.2 Ændring af kontrolboksposition

Advarsel
Før enhver demontering af pumpen

skal anlægget være tømt for væske,
eller afspærringsventilerne på begge
sider af pumpen skal være lukkede da
pumpemediet kan være brændende
varmt og under højt tryk.

4.3 Isolationsskaller

Bemærk

Forsigtig

Bemærk

12 mm

7 mm

Det anbefales at montere isolations­skaller på pumpen.

• Isolationsskaller til pumper i varmeanlæg er med­leveret.

• Isolationsskaller til pumper i airconditionanlæg er
tilbehør og skal bestilles separat. Kontakt ven­ligst Grundfos.

Montering af isolationsskaller øger pumpens dimen­sioner. Se den stiplede linje på målskitserne på 8 og

9.

Isolationsskaller leveres kun til enkeltpumper.

4.4 Dobbeltpumper

Dobbeltpumper leveres med et GENI-modul
monteret på kontrolboksen på hvert pumpehoved.
Modulerne er forbundet via et kabel. Modulerne
bestemmer pumpens driftsform, se afsnit

7.9.1 Dobbeltpumpestyring.

Dobbeltpumper i vandret rørledning
skal altid monteres med en automat­udlufter (Rp 1/4) i pumpehusets øverste
del, se fig. 1.

Udlufteren er ikke medleveret.

.

Fig. 1 Automatudlufter

4.5 Kontraventil

Hvis der er monteret en kontraventil i rørstrengen, se
fig. 2, skal pumpen indstilles så pumpens minimale
afgangstryk til enhver tid overstiger ventilens lukke­tryk. Vær især opmærksom ved proportionaltryk­regulering (reduceret løftehøjde ved lavt flow).

Tilsætning af væsker med massefylde
og/eller kinematisk viskositet større
end vands vil forårsage reduceret
hydraulisk ydelse.

5. El-tilslutning

El-tilslutning og beskyttelse skal foretages i henhold
til de lokale forskrifter.

Advarsel
Pumpen skal tilsluttes en ekstern net-

spændingsafbryder med en bryde­afstand på min. 3 mm i alle poler.

Der kan vælges jording eller nulling
som beskyttelse mod indirekte berø­ring.

Megning skal foretages ifølge afsnit

10. Megnin g.
Hvis pumpen tilsluttes en elektrisk

installation hvor der bruges fejlstrøms­afbryder, skal denne være af typen
HPFI eller PFI som afbryder når der
registreres en fejlstrøm med DC-ind­hold (pulserende jævnstrøm).
Den skal være mærket med dette sym­bol:

• Pumpen kræver ikke ekstern motorbeskyttelse.

• Kontrollér at forsyningsspænding og frekvens
svarer til værdierne på typeskiltet.

5.1 Forsyningsspænding

7. Funktioner

Langt de fleste funktioner kan indstilles direkte på pumpens betjeningspanel. Enkelte funktioner kan dog kun
indstilles med R100 og via udbygningsmoduler.

På pumpens betjeningspanel, se fig. 11, side 18:

• AUTO

ADAPT (fabriksindstilling)

Anbefales i hovedparten af alle varmeanlæg.
Under drift tilpasser pumpen sig automatisk til den aktuelle anlægskarakteristik.
Pumpens energiforbrug og støjniveau minimeres hvilket reducerer driftsomkostningerne og øger komfor­ten.

• Proportionaltrykregulering
Pumpens løftehøjde ændres løbende i forhold til vandbehovet i anlægget. Det ønskede sætpunkt kan
indstilles direkte på pumpens betjeningspanel.

• Konstanttrykregulering
Pumpens løftehøjde holdes konstant, uafhængigt af vandbehovet. Det ønskede sætpunkt kan indstilles
direkte på pumpens betjeningspanel.

• Automatisk natsænkning
Pumpen skifter automatisk mellem normaldrift og natsænkning afhængigt af fremløbstemperaturen.
Automatisk natsænkning kan kombineres med ovennævnte reguleringsformer.

Yderligere funktioner:
Med fjernbetjeningen R100:

• Konstantkurvedrift
Konstant pumpehastighed på eller mellem maks.- og min.-kurve.

• Temperaturføring
Pumpens løftehøjde varieres afhængigt af medietemperaturen.

Via udbygningsmoduler:
