4.3.5 Functional principle of diaphragm leakage
detection
Pumps with diaphragm leakage detection (MLS)
have a special dosing head flange for an
optoelectronic sensor. The pump is supplied with the
diaphragm leakage sensor (MLS) already installed.
The optoelectronic sensor contains:
• infrared transmitter
• infrared receiver.

Fig. 6

Diaphragm leakage sensor (MLS)

If the diaphragm leaks,
• the liquid enters the dosing head flange.
• the light refraction changes.
• the sensor emits a signal.
The electronics operates two contacts, which can be
used, for example, to trigger an alarm signal or to
switch off the pump.
4.3.6 Flow Monitor for dosing control
The pressure sensor (Flow Monitor pump option) is
used as a dosing controller and to monitor the
pressure for the whole power ranges.
The Flow Monitor for dosing control consists of a
pressure sensor integrated in the dosing head.
The pressure sensor is available as Flow Monitor
pump option. The pressure sensor is fitted to the
pump on delivery. Upgrades are not possible.
Note

Pressure control is primarily used to
protect the pump. This function is not
a substitute for the overflow valve.

4.3.7 HV variant for liquids which are more
viscous than water
All HV-variant pumps are equipped with springloaded valves, some have a larger nominal diameter
and adapters.

Note

Note that the HV-variant pump has
other dimensions and that other
connection line dimensions might be
required!

downwards and without loops.

Note

There is only a limited amount of time
available to change the tank, depending
on the pump type and dosing flow, e.g.
30 seconds at a dosing flow of 6 l/h!
If air has been sucked in, briefly
increase the stroke setting to 100 %
and switch the pump to continuous
operation.

Note

First see sections 5. Installation,
7. Start-up / shutdown and
7.2 Operating the pump. Only the
additional functions are described in
this section.

9.1 Menu levels
Menu levels used in the control unit
• First function level: for selecting and setting the
operating modes of the pump (Manual, Contact,
Analog), performing the batch and timer functions
and starting the pump.
• Second function level: for setting and viewing
additional functions, selecting and setting the
batch and timer functions and setting the access
code to protect the pump against unintentional or
unauthorised access to pump settings.
• Service level: for setting the pump type and the
unit of display for the dosing flow (l/h or gal/h) and
setting the inputs and outputs.
Saving user settings
The pump settings are automatically saved
approximately every 10 minutes and remain as they
are even after the power supply has been switched
off.

9.2 General functions of the control unit
9.2.1 Deaeration and suction
If the "Start/Stop" button is pressed for longer than
1 second, the pump switches to continuous
operation for as long as the button is held down
(e.g. for suction or deaeration).
This happens regardless of the selected operating
mode. (In batch or timer mode, the pump has to be
stopped first.)
9.2.2 Locking "run"
The pump can be locked to avoid manual stopping.
When activating this function (service level), the
pump starts running with the present settings and
cannot be stopped using the "Start/Stop" button.
It is still possible to acknowledge error messages
using the "Start/Stop" button.
Stopping the pump when the locking "run" is
activated
• If remote on/off is connected, use remote off.
• Disconnect the pump from the power supply.
Note

For "Batch manual", the "Run" button
should not be locked as the pump then
runs in continuous operation.

9.2.3 Two-stage tank-empty signal
This function is used to provide a warning when the
tank is almost empty and to switch off the pump
when the tank is empty. To use the pre-empty signal,
ensure that the suction line is equipped with two float
switches.

Pre-empty signal
The pre-empty signal can be an error signal or a preempty signal at socket 3. For a pre-empty signal,
relay 1 must be set to "Pre-empty signal". See
sections 6.1 Connecting the signal lines for DDI 209
and 9.7.1 Modifying the switch assignment.
When the contact of the corresponding float switch
closes,
• the error signal relay or pre-empty signal relay
switches on, but the pump is not switched off.
• The LED flashes red.
• The empty-signal symbol flashes in the display.

Fig. 37 Display: motor monitoring
• The pump is stopped.
• The red LED flashes.
For possible errors and their correction, see section
11. Fault finding chart.

Once the error has been corrected,
• press the "Start/Stop" button to acknowledge the
error.
9.2.6 Remote on/off
The pump can be switched off remotely (e.g. from a
control room).
• If switched off remotely, the pump does not
respond to any input signals or to operator input.
Exception: The pump can still be stopped and
deaerated manually.
• "Stop" lights up in the display.
• The yellow LED lights up.
• When switched on remotely, the pump returns to
the state it was in before it was switched off. If, for
example, the pump was previously in "Stop"
mode, it returns to this mode once it is switched
on.
9.2.7 Memory function
Contact signals, which cannot be processed
immediately, can be stored and subsequently made
available to the pump for processing. A maximum of
65,000 contact signals can be stored.
• Without memory: If the pump is running when a
contact signal is received, the signal is ignored.
The pump performs the current dosing, then it is
again ready to receive new contact signals, i.e. it
rejects excess contacts.
• With memory: If the pump is running when a
contact signal is received, the signal is stored in
the memory. First, the pump performs the current
dosing, then it processes the contact signals from
the memory.
The contents of the memory are deleted:
• by switching off the power supply
• by switching the operating mode.
The contents of the memory are not deleted:
• by actuating the remote on/off contact
• by pressing the "Start/Stop" button
• by continuous operation.
Note

The memory function can be enabled
and disabled in the second function
level.

9.2.8 Flow Monitor
The pump can be equipped with a pressure sensor
(Flow Monitor pump option).
Based on the pressure measured by the sensor and
on the motor position, an indicator diagram is
created. Possible dosing faults or the exceeding of
the permissible counter-pressure are detected
reliably and indicated by the display or the error
message output.

The following errors are recognised:
• Pressure exceeded (the pump is stopped and
restarts automatically when the pressure
decreases).
• Dosing error (the pump doses 30 % to 100 % less
due to a leaking discharge valve or suction valve,
a clogged suction line or an air bubble in the dosing head).

Caution

Depending on the operating conditions,
it may be impossible to detect dosing
errors which are caused by leaking
suction valves!

The dosing controller and dosing control functions
can be switched on and off independently of each
other. It is always possibly to display the pressure
that has been measured during operation whenever
the pressure sensor is connected.
Note

For information about operating the
pump with the Flow Monitor, see
section 9.10 Flow Monitor.

9.3 Signal outputs
The control unit has the following signal outputs,
e.g. in order to return a signal to the control room.
9.3.1 Current signal output
Note

To use the control signal output, see
section 9.9 Current signal control
0-20 mA / 4-20 mA.

The current flow rate of the pump is output as a
current signal.
• Current output 0-20 mA in the following mode:
– Current control 0-20 mA.
• Current output 4-20 mA in the following modes:
– Current control 4-20 mA
– Manual
– Contact
– Batch dosing with manual/contact start
– Timer with manual/contact start.

Note

The current output is linear between
4 (0) mA at flow rate = 0 and 20 mA at
maximum flow rate Qmax. (default
setting) or the corresponding weighting
value pair.

9.3.2 Error signal
Used to return various error states to the control
room.
9.3.3 Stroke signal / pre-empty signal / pulse
input
Depending on the relay setting, the contact output
receives a signal in these cases:
• for each complete stroke of the pump, or
• a pre-empty signal input, or
• each pulse input at the pump.
To set the relay, see section 9.7.1 Modifying the
switch assignment.

9.6 Calibration
The dosing flow display is set by default for an
operating counter-pressure of 3 bar. Calibration can
be used to set the pump flow to the actual operating
conditions.
Calibrate the pump under normal operating
conditions with the discharge line connected and at
operating counter-pressure.

Note

The dosed volume must be gauged in
litres during calibration, e.g. by drawing
the dosing medium from a gauged tank.
(For an alternative for pumps with Plus3
system, see section 9.6.1 Calibrating
pumps with Plus3 system (internal
calibration)).

Due to the small stroke volume of the
DDI 0.4-10, calibration is essential for
a precise dosing flow.
Before calibrating the DDI 0.4-10,
deaerate the pump and then let it run
for 15 minutes at operating counterpressure with full stroke rate.

"OFF CAL" appears in the display.
1. Press the "Up" button.
– "ON CAL" appears in the display.
2. Press the "Start/Stop" button.
– Calibration is started. The LED flashes green
and "Run" flashes in the display.
• 200 strokes are performed by default. The
number of strokes performed appears in the
display.
• Press "Start/Stop" to stop at any stroke value.
– The LED lights up red.
3. Press the "Start/Stop" button.
– The current calibration value is displayed
(not with replacement circuit boards!).

4. Use the "Up" and "Down" buttons to enter the
calibration value (gauged volume in ml).
• Press the "Menu/Info" button (confirm the setting
and move on to the next menu item), or
• press the "Start/Stop" button (confirm the setting
and close the second function level).
The calibration process does not
change the setting for the assignment/
weighting of the current input and
output for the flow rate.
If a current input or output is used,
check after calibration to determine
whether a new current weighting is
required.

without gauging the dosed volume during
calibration
If you do not gauge the dosed volume, you can
determine the "calibration value" from the following
dosing capacity curves in order to adjust your pump
to the operating counter-pressure.
The curves represent 200 strokes:
• Dosing medium with a viscosity similar to water
• Pumps without Plus3 system.

Select the current control used
(0-20 mA / 4-20 mA) before weighting.

Note

Weighting can be set independently of
the current input value that is currently

corresponds to the set current input
value [mA] always appears in the
display.

The set weighting is saved in the pump.
The values are retained, e.g. when the
power supply is switched off, and are
also active when current weighting is
called in the second function level.

Note

Even for current input/current output assignments
that are already weighted in the second function
level (see curve 3a), subsequent weighting can be
set or weighting can be shifted here. The value for
the maximum flow rate Qselect mA max. at mAmax. is

9.9.2 With calibrated pump
When calibrating the pump for your application and
using current signal control and/or current output,
proceed as follows:
1. Calibrate the pump.
2. Determine the maximum flow rate Qcal by taking a
reading on the pump: Qcal is the maximum
adjustable flow rate after calibration, e.g. in
manual mode, or the displayed flow rate in
continuous operation (press and hold down the
"Start/Stop" button for longer than 1 second).
3. To set the current input/current output weighting,
see section 9.9.3 Setting the weighting.

Note

For unweighted assignment (curves
1a and 2a, see fig. 50) select the
following reference points:
L: mAmin. = 0 (4) mA / Qselect mA min. =
0 l/h
H: mAmax. = 20 mA / Qselect mA max. =
Qcal.

Note

Qcal is not updated automatically when
the pump is re-calibrated. This protects
the user-defined value pairs. After
calibration, new weighting may be
required!

9.9.3 Setting the weighting

Note

The setting options for weighting
depend on the selected current signal
control. The parameters for 0-20 mA
and for 4-20 mA are independent of one
another. The weighting parameters are
modified and saved according to the
set operating mode.
Select the current control operating
mode used later (0-20 mA / 4-20 mA)
manually or via contact signal before
weighting. (Weighting of the control
output for manual control mode or
contact signal control is the same as
current weighting 4-20 mA.)

2. Use the "Up" and "Down" buttons to enter the
maximum current input mAmax. > mA min.
(e.g. mAmax. = 16 mA).
3. Press the "Start/Stop" button.
– The current value for the mAmax. assigned flow
rate QmA max. appears in the display (the
default value is Qmax.).

4. Use the "Up" and "Down" buttons to enter the
desired value for flow rate QmA max. at mAmax.
(e.g. QmA max. = 8 l/h).
• Press the "Menu/Info" button (confirm the setting
and move on to the next menu item), or
• press the "Start/Stop" button (confirm the setting

Result of weighting
In the example, the following values were entered as
reference points Ld and Hd:
Ld: mA min. = 6 mA, Qselect mA min. = 2 l/h
Hd: mAmax. = 16 mA, Qselect mA max. = 8 l/h.
The curve for current input/current output now
passes through Q = 0 at < 6 mA, from Q = 2 l/h at
6 mA to Q = 8 l/h at 16 mA, and through Q = 8 l/h at
> 16 mA (curve 1d).
In the same way, it is possible to enter a current
weighting with a negative gradient. In order to do
this, the value pair for reference point L must first be
entered with the smaller mA value followed by
reference point H.

In the example, the following values were entered as
reference points Le and He:
Le: mA min. = 2 mA, Qselect mA min. = 12 l/h
He: mAmax. = 16 mA, Qselect mA max. = 2 l/h.
The curve for current input/current output now
passes through Q = 0 at < 2 mA, from Q = 12 l/h at
2 mA to Q = 2 l/h at 16 mA, and through Q = 2 l/h at
> 16 mA (curve 1e).

9.10 Flow Monitor
9.10.1 Application notes
Dosing of degassing media (H2O2, chlorine
bleaching agents)
• For a robust operation, set the number of
permissible error strokes to a value higher than
10.
Dosing of antiscalent (viscosity higher than
20 mPa s), in particular for DDI 0.4-10 with Plus 3
• Use spring-loaded valves for high-viscosity
media.
Dosing of viscous media
• For media with a viscosity higher than 20 mPa s,
spring-loaded suction and discharge valves are
recommended.
• Dosing media with a viscosity higher than 100
mPa s on request.
For batch or timer operation
• Set the number of permissible error strokes to a
value lower than the number of working strokes.
• If, while the pump is stopped, the pressure in the
discharge line falls below the minimum pressure
of 2 bar (e.g. in the event of a leak in the
pressure-loading valve), increase the number of
permissible error strokes so as to prevent
unnecessary error messages.
Ensuring the counter-pressure by a pressure-loading
valve:
• Check the counter-pressure 2 to 3 weeks after
start-up.
– If it is below 2 bar, the pressure-loading valve
has to be re-adjusted.
– If the volume flow is not constant (as, for
example, in the case of contact or analog
control), even small volume flows should not
fall below the minimum pressure or minimum
pressure difference of 2 bar.

9.10.2 Setting the Flow Monitor
In order for the pressure sensor (if installed) to
function as a dosing controller, the dosing controller
must be switched on.
To allow the pump to switch off in the event of
overpressure and to set the cut-off pressure of the
pump, the pressure control function must be
switched on and set.
If no pressure sensor is connected, the pump
determines the pressure from the motor current.

Note

For applications with high
requirements in terms of precision, the
pressure control function must be used
with a pressure sensor.

Switching on dosing controller
Menu item "flow" is open.
• "flow OFF" appears in the display.
1. Press the "Up" button.
– "flow ON" appears in the display.
– The dosing controller is activated.
Switching on pressure control function

When you are setting the cut-off
pressure, be aware that the pressure
measured in the dosing head is higher
than the system pressure. It is
advisable to display the measured
pressure first, see section Displaying
the pressure that has been measured.
The set cut-off pressure should be
higher than the measured pressure in
the dosing head.

9.10.3 Dosing controller function
The pump software monitors the dosing process and
emits a pulse for each dosing stroke. For each
stroke, the "flow" display is momentarily turned off.
• When switched on, the electronics detects
whether the dosing controller is activated.
– "flow" appears in the display.

Dosing error (after start-up operation)
If, after seven successive strokes or after the number
of strokes which have been defined by the user, the
dosing controller does not emit a signal, this is
recognised as an error:
• The error signal relay switches on, but the pump
is not switched off.
• The LED flashes red.
• "flow" and "ERROR" flash in the display.

Warning
When dosing dangerous media,
observe the corresponding safety
precautions!
Risk of chemical burns!
Wear protective clothing (gloves and
goggles) when working on the dosing
head, connections or lines!
Do not allow any chemicals to leak from
the pump. Collect and dispose of all
chemicals correctly!
Warning
The pump housing must only be
opened by personnel authorised by
Grundfos Alldos!
Repairs must only be carried out by
authorised and qualified personnel!
Switch off the pump and disconnect it
from the power supply before carrying
out maintenance work and repairs!

Note

If possible, rinse the dosing head,
e.g. by supplying it with water.

10.3.1 Switching off the pump
1. Switch off the pump and disconnect it from the
power supply.
2. Depressurise the system.
3. Take suitable steps to ensure that the returning
dosing medium is safely collected.
10.3.2 Unscrewing the priming chamber valve
(Plus3 system)
When using the Plus3 system, unscrew the priming
chamber valve (3c) as follows:
1. Remove the cover (L) from the priming chamber.
2. Remove the valve tube (R) with the valve (3c).
3. Unscrew the valve (3c) from the valve tube.

•

At least every 12 months or after 4,000 operating
hours. When dosing crystallising liquids, more
frequently.
In the event of a fault.

10.2.1 Cleaning the valves and diaphragm
• Clean the diaphragm and valves and replace, if
necessary (for stainless-steel valves: inner valve
parts).

Caution

In the event of a diaphragm leakage, the
dosing liquid may leak out of the hole in
the intermediate flange between the
pump and the dosing head. The parts
inside the housing are protected from
the dosing liquid for a short time
(depending on the type of liquid) by
the housing sealing. It is necessary to
check regularly (daily) if liquid is
leaking out of the intermediate flange.
For maximum safety, we recommend
the pump version with diaphragm
leakage detection.

TM03 6264 4506

10.2 Maintenance intervals

•

Spring-loaded DN 4/DN 8 valve:
– Unscrew the valve cover.
– Dismantle the inner parts (as shown in fig. 70).

Caution

The O-rings must be correctly placed in
the specified groove.
Observe the flow direction (indicated
by an arrow)!
Only tighten the valve by hand.

chemicals correctly!
Note

If possible, rinse the dosing head,
e.g. by supplying it with water.

10.4.1 Resetting the diaphragm
When replacing the diaphragm, it must be at the
back dead point (end of suction stroke). As the
stroke usually ends at the front dead point, reset the
diaphragm as follows:
• With the pump stopped (LED lights up red), press
the "Up" and "Down" buttons simultaneously.
– The diaphragm is reset.
10.4.2 Switching off the pump
1. Switch off the pump and disconnect it from the
power supply.
2. Depressurise the system.
3. Take suitable steps to ensure that the returning
dosing medium is safely collected.

See fig. 72 or 73.
1. Loosen the four screws (1q + 2q) on the dosing
head (2).
2. Remove the dosing head (2).
3. Unscrew the diaphragm (Q) counter-clockwise.
– For pumps without Plus3 system:
Replace the sealing diaphragm (3q),
intermediate ring (4q) and support disk (5q).
4. Screw in the new diaphragm (Q).
5. Replace the dosing head (2) and cross-tighten
the screws (1q + 2q).

11. Fault finding chart
Fault

Cause

1. Dosing pump does
not run.

a) Not connected to the mains.

Connect the power supply cable.

b) Incorrect mains voltage.

Switch off the pump. Check voltage and
motor. If the motor is faulty, return the
pump for repair.

c) Electrical failure.

Return the pump for repair.

2. Dosing pump does
not suck in.

3. Dosing pump does
not dose.

Remedy

a) Leaking suction line.

Replace or seal the suction line.

b) Cross-section of the suction line too
small or suction line too long.

Check with Grundfos Alldos
specification.

c) Clogged suction line.

Rinse or replace the suction line.

d) Foot valve covered by sediment.

Suspend the suction line from a higher
position.

e) Buckled suction line.

Install the suction line correctly. Check

f) Crystalline deposits in the valves.

Clean the valves.

g) Diaphragm broken or diaphragm
tappet torn out.

Replace the diaphragm.

h) Empty dosing tank.

Fill the dosing tank.

a) Air in the suction line and dosing
head.

Fill the dosing head and suction line.

b) Viscosity or density of medium too
high.

Check the installation.

c) Crystalline deposits in the valves.

Clean the valves.

d) Valves not correctly assembled.

Assemble the inner valve parts in the
right order and check or possibly correct
the flow direction.

e) Injection unit blocked.

Check and possibly correct the flow
direction, or remove the obstruction.

f) Incorrect installation of lines and
peripheral equipment.

Check the lines for free passage and
correct installation.

g) Empty dosing tank.

Fault

Cause

Remedy

4. Dosing flow of the
pump is inaccurate.

a) Dosing head not fully deaerated.

Repeat the deaeration.

b) Degassing medium.

Check the installation.

c) Parts of the valves covered in dirt or
incrusted.

Clean the valves.

d) Counter-pressure fluctuations.

Install a pressure-loading valve and a
pulsation damper, if necessary.

e) Suction lift fluctuations.

Keep the suction level constant.

f) Siphon effect (inlet pressure higher
than counter-pressure).

Install a pressure-loading valve.

g) Leaking or porous suction line or
discharge line.

Replace the suction line or discharge
line.

h) Parts in contact with the medium are
not resistant to it.

Replace with resistant materials.

Dosing diaphragm worn (incipient
tears).

Replace the diaphragm. Also observe
the maintenance instructions.

Variation of the dosing medium
(density, viscosity).

Check the concentration. Use an
agitator, if necessary.

5. Loud, piercing
noises.

a) At dosing capacities lower than 10 %
of the maximum dosing capacity of
the pump, resonance noises may
temporarily occur at the stepper
motor.

The resonance noise of the stepper
motor does not indicate an error.

6. Liquid leaks out of
the hole in the
intermediate flange
between the pump
and the dosing
head.

a) A diaphragm leakage has occurred.

Replace the diaphragm.

Note

For further error signals for the control unit, refer to the relevant section.
