Glossary

Accumulator

The accumulator serves to compensate for
pressure losses in the piping system downstream
of the pressure booster system which may be
caused by the consumption of small quantities of
water. As a result, the frequency of starts of the
pressure booster system is minimised.

Braking resistor

Takes up the braking power produced during
generator operation.

Certificate of decontamination

A certificate of decontamination is enclosed by the
customer when returning the product to the
manufacturer to certify that the product has been
properly drained to eliminate any environmental
and health hazards arising from components in
contact with the fluid handled.

Dry running protection

Dry running protection devices prevent the pump
from being operated without the fluid to be
handled, which would result in pump damage.

The warranty relating to the operating reliability and safety of the pressure booster

system supplied is only valid if the equipment is used in accordance with its intended
use. (ðSection2.2,Page8)

2.9 Electromagnetic compatibility (EMC)

2.9.1 Interference emission requirements

The EN61800-3 EMC product standard is relevant for electric variable speed drives/
control systems. It specifies all pertinent requirements and refers to the relevant
generic standards for complying with the EMC Directive.

Frequency inverters are commonly used by operators as a part of a system, plant or
machine assembly. It should be noted that the operator bears all responsibility for
the final EMC properties of the equipment, plant or installation.

A prerequisite or requirement for complying with the relevant standards or the limit
values and inspection/test levels referenced by them is that all information and
descriptions regarding EMC-compliant installation be observed and followed.

In accordance with the EMC product standard, the EMC requirements to be met
depend on the purpose or intended use of the frequency inverter. Four categories
are defined in the EMC product standard:

Table4: Categories of intended use

Category Definition Limits to EN55011

C1 Frequency inverters with a supply voltage under 1000V installed in the

first environment (residential and office areas).

Class B

C2 Frequency inverters with a supply voltage under 1000V installed in the

first environment (residential and office areas) that are neither ready to
be plugged in/connected nor are mobile and must be installed and
commissioned by specialist personnel.

Class A, Group 1

C3 Frequency inverters with a supply voltage under 1000V installed in the

second environment (industrial environments).

Class A, Group 2

C4 Frequency inverters with a supply voltage over 1000V and a nominal

current over 400A installed in the second environment (industrial
environments) or that are envisaged for use in complex systems.

No borderline/

boundary

≤ 11 ≤5 C1 Class B

The EN61800-3 standard requires that the following warning be provided for drive
systems that do not comply with category C1 specifications:
This product can produce high-frequency interference emissions that may necessitate
targeted interference suppression measures in a residential or office environment.

2.9.2 Line harmonics requirements

The product is a device for professional applications as defined by EN 61000-3-2. The
following generic standards apply when establishing a connection to the public
power grid:

▪ EN 61000-3-2

for symmetric, three-phase devices (professional devices with a total power of up
to 1kW)

▪ EN 61000-3-12

for devices with a phase current of between 16A and 75A and professional
devices from 1kW up to a phase current of 16 A.

2.9.3 Interference immunity requirements

In general, the interference immunity requirements for a frequency inverter hinge on
the specific environment in which the inverter is installed.

The requirements for industrial environments are therefore higher than those for
residential and office environments.

The frequency inverter is designed such that the immunity requirements for
industrial environments and, thus, the lower-level requirements for residential and
office environments, are met and fulfilled.

The following relevant generic standards are used for the interference immunity test:

Design The fully automatic pressure booster system is equipped with vertical high-pressure

pumps (2) (all of which are speed-controlled) for pumping the fluid handled to the
consumer installations in the set pressure range.

Function Either two or three pumps (2) are controlled and monitored by motor-mounted

frequency inverters.
As the demand increases or decreases, pumps are started and stopped automatically.
As soon as the demand increases again after one pump has been stopped, another

5 Description

17 of 68

KSBDeltaSolo / KSBDeltaEco

pump which has not been in operation before is started up.
The stand-by pump is also included in the alternating cycle.
The standard setting is for the pressure booster system to start automatically as a
function of pressure; the actual pressure is measured by an analog pressure
measuring device (pressure transmitter).
As long as the pressure booster system is in operation, the pumps are started and
stopped as a function of demand (standard setting). In this way it is ensured that the
individual pumps operate only in line with actual demand.
The use of variable speed pumps reduces wear as well as the frequency of pump
starts in parallel operation. If a duty pump fails, the next pump is started up
immediately. A fault is output, which can be reported via volt-free contacts (e.g. to
the control station).
If the demand drops towards 0, the pressure booster system slowly runs down to the
stop point.

As standard, one of the pumps is on stand-by. The control system defines each of the
pumps as stand-by pump in alternation. This prevents stagnation of water in any of
the pumps. Via a parameter in the control system the stand-by pump function can be
disabled in order to operate the system without stand-by function.

The pressure booster system is designed with integrated electronic dry running
protection.
A digital lack-of-water indicator can be connected to the corresponding contacts.

During commissioning and after every power failure, the pressure booster system fills
the piping system slowly, to prevent any damage to the piping by surge pressure.

5.6 Noise characteristics

Pressure booster systems are available with different numbers and sizes of pumps.
Therefore, the expected total sound pressure level in dB(A) needs to be calculated.
Refer to the pump's operating manual for the noise characteristics of the individual
pumps.

Calculation example:

Number of pumps Expected total sound pressure level

in dB(A)

Single pump . . . . . dB(A)

2 pumps, total +3 dB(A)
3 pumps, total +4,5 dB(A)
4 pumps, total +6 dB(A)
5 pumps, total +7 dB(A)
6 pumps, total +7,5 dB(A)

Example Single pump 48 dB(A)
4 pumps, total +6 dB(A)

54 dB(A)

The expected total sound pressure level of 54dB(A) for this configuration may
develop when all four pumps are running under full-load conditions.
Refer to the pumps' operating manual for the noise characteristics of the individual
pumps.

6 Installation at Site

6.1 Installation

Install pressure booster systems either in the technical equipment room or in a well­ventilated, frost-free, lockable room used for no other purpose. No harmful gases are
allowed to enter the place of installation. An adequately sized floor drain (leading to
a sewer or equivalent) must be provided.

The pressure booster system is designed for a maximum ambient temperature of 0°C
to +40°C at a relative humidity of 50%.

NOTE

Do not install pressure booster systems next to sleeping or living quarters.

The anti-vibration mounting of the pressure booster system provides adequate
insulation against solid-borne noise. If expansion joints (KSB accessory) are used for
damping vibrations, their fatigue strength (endurance limit) must be given due
consideration. Expansion joints must be easily replaceable.

6.2 Checks to be carried out prior to installation

Place of installation

WARNING

Installation on mounting surfaces which are unsecured and cannot support the
load

Personal injury and damage to property!

▷ Use a concrete of compressive strength class C12/15 which meets the

requirements of exposure class X0 to EN206-1.

▷ The mounting surface must have set and must be completely horizontal and

even.

▷ Observe the weights indicated.

NOTE

The anti-vibration mounts of the pressure booster system provide adequate
insulation against solid-borne noise.
Thanks to level-adjustable feet (KSB accessory) the pressure booster system can also
be installed in a horizontal position on uneven floors.

For pressure booster systems with Movitec 2, 4, 6, 10 and 15, level-adjustable feet are
available as accessories.

Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawings.

6.3 Installing the pressure booster system

WARNING

Top-heavy pressure booster system

Risk of personal injury by pressure booster system tipping over!

▷ Pressure booster systems awaiting final installation must be secured against

tipping over.

▷ Firmly anchor the pressure booster system.

6 Installation at Site

20 of 68

KSBDeltaSolo / KSBDeltaEco

Remove all packaging before installing the pressure booster system. Connect the
pressure booster system's inlet line and discharge line to the corresponding site
distribution lines.

NOTE

In order to avoid transmission of piping forces onto the pressure booster system
and transmission of solid-borne noise, we recommend installing length-limited
expansion joints.

Allow sufficient space for maintenance and repair work.

ü All structural work required has been checked.
ü The dimensions of the concrete foundation are correct, and the concrete has set

firmly.

1. Mark out the anchoring holes on the floor as shown in the outline drawing.

2. Drill the holes (max. diameter: 12mm).

3. Insert plug fixings of appropriate size.

4. Set the pressure booster system down in its correct installation position.

5. Use suitable bolts to firmly anchor the pressure booster system.

6.4 Installing the piping

Make sure that piping is installed without transmitting any stresses or strains. The use
of length-limited expansion joints (see accessories) is recommended.

CAUTION

Air pockets in suction line

Pressure booster system cannot prime!

▷ Lay piping with a continuously rising slope (as shown).

Suction lift operation

Incorrect Correct

NOTE

For suction lift operation install suitable swing check valves at the suction line ends
which are submerged in the fluid handled. Take into account the head losses
caused by these swing check valves.
Do not exceed the maximum suction lift of the pumps.

6.4.1 Fitting an expansion joint

DANGER

Sparks and radiant heat

Fire hazard!

▷ Take suitable precautions to protect the expansion joint if any welding work is

carried out nearby.

6 Installation at Site

21 of 68

KSBDeltaSolo / KSBDeltaEco

CAUTION

Leaking expansion joint

Flooding of installation room!

▷ Regularly check for cracks or blisters, exposed fabric or other defects.

ü The expansion joint has a length limiter with solid-borne sound insulation so as

to be able to absorb reaction forces.

1. Install the expansion joint in the piping free of twist or distortion. Never use the
expansion joint to compensate for misalignment or mismatch of the piping.

2. Tighten the bolts evenly and crosswise during assembly. The ends of the bolts
must not protrude from the flange.

3. Do not apply paint to the expansion joint. Protect it from any contact with oil.

4. The position of the expansion joint within the pressure booster system must
allow easy access and inspection and it must, therefore, not be insulated along
with the piping.

5. Expansion joints are subject to wear.

6.4.2 Installing a pressure reducer

NOTE

A pipe length of approximately 600 mm must be provided on the inlet side to
accommodate a pressure reducer, if necessary.

NOTE

A pressure reducer must be installed

- if the inlet pressure fluctuation is too high for the pressure booster system to
operate as intended or

- if the total pressure (inlet pressure plus shut-off head) of the pressure booster
system exceeds the design pressure.
The maximum pump discharge pressure at zero flow point is reached in manual
mode.

A minimum pressure gradient of 5 metres is required for the pressure reducer to
fulfill its function. The pressure downstream of the pressure reducer (downstream
pressure) is the basic parameter for determining the pump head.

For example:

The inlet pressure fluctuates between 4 and 8 bar. A pressure reducer is needed
upstream of the pressure booster system on the inlet side.
Min. inlet pressure (p

inl

)=4bar
Min. pressure gradient=0.5bar
Downstream pressure=3.5bar.

6.5 Installing unpressurised inlet tanks

Installation and location of an unpressurised inlet tank together with the pressure
booster system are governed by the same rules applicable to the pressure booster
system.

Install the closed PE inlet tank (under atmospheric pressure) available as a KSB
accessory as described in the installation instructions supplied with the tank.

CAUTION

Contamination in the pressure booster system

Damage to the pumps!

▷ Clean the tank before filling it.

6 Installation at Site

22 of 68

KSBDeltaSolo / KSBDeltaEco

The tank must be connected mechanically and electrically to the pressure booster
system prior to commissioning of the system.

6.6 Fitting the dry running protection device

Install the dry running protection device supplied together with the pressure booster
system as a separate, non-fitted accessory, or supplied at a later date for retrofitting,
in accordance with its operating instructions and connect it to the switchgear and
controlgear assembly.
The switchgear and controlgear assembly is provided with the requisite inputs.

For a multiple pump system:

1. For information on connecting the external dry running protection device, refer
to the circuit diagram.

For a single-pump system:

1. Remove the front cover to access the terminal strip.

can be in fault (standstill) or warning (operational) status. The user can also find
previous messages in the history.

Messages

All monitoring and protective functions trigger warnings or alerts. These are
signalled via the amber or red LED of the LED traffic light function.

A corresponding message is output on the control panel display. If more than one
message is output, the last one is displayed. Alerts have priority over warnings.

Pending messages If a message has occurred and been acknowledged but has not gone, this message

will be listed in the Pending Messages menu. All current messages can be displayed in
the Diagnosis menu under Pending Messages (2-1). Active warnings and alerts can
also be connected to the relay outputs.

Acknowledging and resetting messages

NOTE

Depending on the combination of settings, the frequency inverter could
conceivably restart automatically after acknowledgement/reset or when the cause
of the malfunction or fault has been eliminated.

Acknowledgement You can acknowledge the message once the cause has been rectified. Messages can

be acknowledged separately in the Diagnosis menu. A message can also be
acknowledged via a digital input. Digital input 2 is defaulted for this purpose.

Overview of warnings and alerts (ðSection10,Page52)
Messages can be acknowledged as follows:

Table16: Acknowledgement types for messages

Property of message Type of acknowledgement

Self-acknowledging Message self-acknowledges if condition for message has gone.
Self-acknowledging

(configurable)

Users can choose between self-acknowledging and acknowledging manually.

Partially self­acknowledging

Alerts that are partially self-acknowledging carry out self-acknowledgement in
increasingly large intervals after the alarm condition has gone. If the alert occurs
repeatedly within a specific time window, no additional self-acknowledgement is
carried out.

As soon as the alarm condition of a pending alert no longer exists, the time interval is
started. When this interval expires, automatic acknowledgement takes place.

If the alert occurs again within 30seconds after the time interval has started, the
interval is extended by one increment. Should this not be the case, the previous
(shorter) time interval is reverted to and corresponding action is taken again in
30seconds. The time intervals are 1second, 5seconds, 20seconds, and endless (i.e.
manual acknowledgement is required). When the 20-second interval is extended, self­acknowledgement no longer takes place.

Non-self-acknowledging Must be acknowledged manually.

Time stamp If a message is not acknowledged and its condition comes and goes several times in

this time window, the first occurrence of the message is always used for the Message
Come time stamp. The Message Condition Gone time stamp, however, always shows
the last time the message condition was no longer active.
