4.3 Controller

4.3.1 General description

The Fire RS extinguishing water booster set is operated via a

controller especially designed for this purpose. The controller is

for monitoring and for switching on both pumps automatically. The

controller is placed in a control cabinet being delivered separately

for wall mounting.

In case of small leakages the jockey pump starts automatically

when the pressure is lower than the pressure set on the pressure

switch for the jockey pump. If the stop pressure is reached the

jockey pump stops again.

As soon as the sprinklers are activated and water is consumed, the

pressure in the discharge pipe is reduced. If the pressure becomes

lower than the starting pressure set on the pressure switches, the

jockey pump will start automatically rst and then the main pump

via the corresponding pressure switches. The pressure switch for

the main pump must be set to a higher start pressure than the pres-

sure switch for the jockey pump. Both pumps are stopped manually

via the controller. For safety reasons, a redundant pressure switch

is connected in addition to the pressure switch for the main pump.

Manual pump operation is provided via a manual switch for com-

missioning, servicing and testing for both pumps. In case of dry

running the jockey pump will be stopped by the pressure switch

mounted at the suction manifold. A dry running for the main pump

is not possible, as the main pump should not stop for any reason

in case of re.

The controller is operated by means of the control panel and the

manual switches in the cabinet door.

switches, the jockey pump will start automatically first and then

the main pump via the corresponding pressure switches. The

pressure switch for the main pump must be set to a higher start

pressure than the pressure switch for the jockey pump.

Both pumps are stopped manually via the controller. For safety

reasons, a redundant pressure switch is connected in addition to

the pressure switch for the main pump.

Manual pump operation is provided via a manual switch for

commissioning, servicing and testing for both pumps.

In case of dry running the jockey pump will be stopped by the

pressure switch mounted at the suction manifold. A dry running

for the main pump is not possible, as the main pump should not

stop for any reason in case of fire.

4.4 Functions

4.4.1 Operating functions

Automatic operation of the main pump

Automatic operation is the normal operating

mode. For this mode, the selector switch for the

system must be set to “AUT”.

When the extinguishing water booster set is in automatic mode,

only the green “POWER SUPPLY” indicator light in the control

panel is on. All other alarm and status indicator lights should be

off.

As soon as the sprinklers are activated and water is consumed, the

pressure in the discharge pipe is reduced. If the pressure falls be-

low the cut-in pressure set on the corresponding pressure switch,

the main pump will start automatically. The “PUMP RUNNING” indi-

cator light will light up, and the AR3 digital output will be activated.

Furthermore, the “PUMP ON DEMAND” indicator light will light up,

and the AR2 digital output will be activated.

If the main pump set cannot start due to a fault, the yellow “START

FAILURE” indicator light will light up, and the AR5 digital output will

be activated. The alarm indication will be reset automatically, when

the fault has disappeared.

It is only possible to stop the main pump manually by setting the

selector switch to “0” and pressing [Stop].

For safety reasons, a redundant pressure switch should always

be connected in addition to the primary pressure switch.

See also section 12.1 Automatic operation.

Manual operation of the main pump

During start-up and for test purposes, the main pump can be

started manually by turning the selector switch for the main pump

to “TEST” and pressing [Start]. When [Start] is pressed, the start

relay is activated by bypassing the pressure switch in the discharge

line. The red “PUMP RUNNING” indicator light will light up, and the

AR3 digital output will be activated. In manual mode, the “PUMP

ON DEMAND” indicator light does not light up, and the AR2 digital

output will be deactivated. To switch off the pump press the [Stop]

button.

To restore automatic mode, the selector switch for the main pump

must be turned back to “AUT” position.

See also section 12.2.1 Jockey pump.

Dry run protection of the jockey pump

The jockey pump is protected against dry running by a pressure

switch placed in the suction manifold. In case of dry running the

jockey pump stops. After the dry running condition disappear the

jockey pump starts automatically again, if the request still exists.

Overpressure compensation

To protect the extinguishing water booster set against too high

pressure a safety valve has been installed in the discharge pipe

of the main pump being activated at 12 bar.

4.4.2 Monitoring functions

You will find an overview of the status and fault indications related

to the monitoring functions in section 8.2 Status indications and

section 8.3 Fault indications.

Controller power supply

The connection of the controller to the mains is monitored in

order to determine whether the phase sequence is correct. If it is,

the "POWER SUPPLY" indicator light is on, and the AR1 digital

output is activated.

Position of selector switch for main pump

The position of the selector switch for the main pump is

monitored. If this selector switch is not in position "AUT" the

yellow "MOTOR SUPPLY FAILURE/NON AUTO" indicator light is

flashing.

Start request of main pump

If, in automatic mode, there is a start request from either a

pressure switch (DI1 or DI2 open) or the level switch in the

priming tank (DI3 closed), the "PUMP ON DEMAND" indicator

light will light up, and the AR2 digital output will be activated.

In manual mode, the "PUMP ON DEMAND" indicator light does

not light up, and the AR2 digital output remains deactivated.

Operation of main pump

It is possible to monitor whether the main pump is running via an

additional pressure switch built into the discharge line. If the start

relay for the motor is activated and the contact in the DI4 digital

input is closed, the "PUMP RUNNING" indicator light will light up,

and the AR3 digital output will be activated.

If there is no signal from the pressure switch to the DI4 digital

input on the pressure side, although the start relay has been

activated by the motor, the "START FAILURE" indicator light will

light up, and the AR5 digital output will be activated.

Power supply to the motor of the main pump

The power supply to the motor is monitored by means of a phase

monitoring relay. If there is a voltage failure on the motor

terminals when the start relay is activated, the yellow "MOTOR

SUPPLY FAILURE/NON AUTO" indicator light will light up, and

the AR4 digital output will be activated.

Operation of jockey pump

If, in automatic mode, there is a start request from the pressure

switch for the jockey pump (DI5 open) and the start relay for the

motor is activated, the "JOCKEY RUN" indicator light will light up.

Motor failure of the jockey pump

If the motor of the jockey pump is overheated, the red "JOCKEY

ALARM" indicator light will light up.

7. Operating conditions

7.1 Pumped liquid

The sprinkler pump is suitable for pumping clean and non-

aggressive fire extinguishing water not containing additives.

7.2 Maximum operating pressure

The maximum operating pressure of the extinguishing water

booster set is limited to 12 bar by a safety valve. However, some

of the CR pumps are designed for a maximum pressure of 10 bar

only. These pumps are equipped with a bearing flange in order to

withstand a higher operating pressure.

7.3 Minimum inlet pressure

The minimum inlet pressure "H" in m, required during operation to

avoid cavitation in the pump, can be calculated by means of the

following equation:

H = pbx 10.2 – NPSH – Hf– Hv– Hs

If the value determined for H is positive, the pump can be

operated at a maximum suction lift of "H" metres. However it is

assumed that there is a positive inlet pressure, as the

extinguishing water booster set will be connected to the water

supply network directly.

If the value determined for H is negative, a minimum inlet

pressure of "H" metres is required. The value calculated for H

must be available at the suction port of the pump.

The maximum permissibleinlet pressure must not exceed 8 bar.

However, the actual inletpressure + pressure when the pump is

operating against a closed valve must always be lower than the

maximum operating pressure.

For some of the CR pumps the maximum permissible inlet pres-

sure is lower than 8 bar.These pumps are equipped with a bear-

ing ange in order to withstand a higher maximum inlet pressure.

7.5 Minimum owrate

Warning

The CR booster pumps are not allowed to run against a

closed valve as this may cause an unacceptable

temperature increase or the formation of steam.

This may cause damage to the CR booster

pumps.

The curves below show the minimum ow rate as a percentage of

the nominal ow rate in relation to the liquid temperature.

7.6 Temperatures

Liquid temperature

The main pump and jockeypump are designed for liquid

temperatures up to a maximum of 120 °C. Ambient tem-

perature

The maximum permissible ambient temperature for the extinguish-

ing water booster set is +40 °C. This is determined by the electric

motor and the controller.

7.7 Relativeairhumidity

The relative air humidity must not be too high to prevent condensa-

tion of moisture in the air.This can lead to damage of the controller

or the electric motor.If humidity is a problem, install room heating

incorporating a hydrostat.

If the ambient temperatureexceeds the above temperature values

or the pump is installed at an altitude exceeding the above altitude

values, the motor must not be fully loaded due to the risk of over-

heating. Overheating may result from excessive ambient tempera-

tures or the low density and consequently low cooling effect of the

7.8 Effect of ambient temperature and altitude on

motor output

If the ambient temperature exceeds the above temperature

values or the pump is installed at an altitude exceeding the above

altitude values, the motor must not be fully loaded due to the risk

of overheating. Overheating may result from excessive ambient

temperatures or the low density and consequently low cooling

effect of the air. In such cases, it may be necessary to use a

of 70 °C must not be loaded more than 89 % of the rated output. If

the pump is installed 4750 metres above sea level, the motor

must not be loaded more than 89 % of the rated output.

In cases where both the maximum temperature and the maximum

altitude are exceeded, the derating factors must be multiplied

(0.89 x 0.89 = 0.79).

9. Delivery, transport, storage

Check the extinguishing water booster set care-

fully for transport damage and missing parts on

delivery, and transport and store them correctly

before installation.

9.1 Delivery

The entire sprinkler pump system is delivered from factory in an

open wooden box or in a closed box made of wood/plywood de-

signed for transportation with forklift or pallet trucks.

9.2 Transport

Warning

When lifting the entire extinguishing water boost-

er set, never use the lifting eyes of the individual

components or the manifolds. Use only suitable

lifting equipment in proper condition. See also

the weight specications on the nameplate.

When lifting, the lifting point should always be above the centre of

gravity of the sprinkler pump system.

9.3 Storage

Store the extinguishing water booster set in such

a way that corrosion and damage are avoided.

In order to prevent water, dust, etc. from entering the sprinkler

pump, all openings must be covered appropriately until the pipes

are installed. If this is not complied with, the costs involved in

dismantling the sprinkler pump to remove foreign bodies after com-

missioning are considerable.

Turn the pump shaft manually once a month to prevent the

mechanical shaft seal from seizing up.

10. Installation

Warning

The extinguishing water booster set must be

installed and connected in accordance with local

regulations and by qualied personnel.

Installation of the extinguishing water booster

set must be carried out in accordance with the

following instructions. If these instructions are

not followed, malfunctions can result which can

cause damage to the sprinkler pump system.

10.1 Mounting

10.1.1 Installation site

Warning

Installation and operation in a potentially

explosive environment are not permissible.

Warning

The control cabinet must be placed so that water

from the pump or pipework cannot pose any dan-

ger.

Warning

The permissible oor loading must not be

exceeded. The weight of the sprinkler pump

system is stated on the nameplate.

In case of an installation on a foundation also

consider the weight of the foundation.

The extinguishing water booster set Fire RS EN CR with its

associated control is only suitable for indoor installation.

It must be installed in a well ventilated, dry and frost-free location.

Especially the control cabinet should not be exposed to direct solar

radiation.

even and solid surface, for instance a concrete oor or founda-

tion.

Allow sufcient clearance around the extinguishing water booster

set to enable inspection, repair and assembly work.

10.1.2 Foundation

We recommend that you install the extinguishing water booster set

on a concrete foundation which is heavy enough to provide perma-

nent and rigid support for the entire system. The foundation must

be capable of absorbing any vibration, normal strain or shock.

As a rule of thumb, the weight of the concrete foundation should

be 1.5 times the weight of the extinguishing water booster set.

The concrete foundation must have an absolutely level and even

surface. In the foundation, install appropriate anchorage dowels to

fasten the sprinkler pump system.

When setting up the foundation, make sure that the foundation is

200 mm larger in length and width than the dimensions of the base

frame.

The minimum height of the foundation (hf) can be calculated as fol-

lows, if the mass of the foundation is assumed to be 1.5 times the

total mass of the sprinkler pump system:

values stated on the nameplate.

The electrical connection must be made in accordance with the

wiring diagram in the control cabinet.

Procedure

• The connection to the mains supply must be fitted with a fuse

of the correct size, in accordance with local regulations, and

connected to the main switch in the control cabinet. PE must

be connected using the PE terminal block.

• Pressure switch 1 for the main pump must be connected to

terminals 6 and 7 in the control cabinet, and pressure switch 2

for the main pump to terminals 8 and 9.

• The pressure switch for the jockey pump must be connected to

terminals 2 and 52 in the control cabinet.

• The pressure switch for dry running protection of the jockey

pump must be connected to terminals 53 and 54 in the control

cabinet. If this pressure switch should not be used, put a

cable/bridge between terminal 53 and 54

• The additional pressure switch for the "Pump running"

indication is to be connected to terminals 12 and 13. If no

additional pressure switch is used, put a cable/bridge between

terminal 12 and 13.

• If there is a level switch for measuring the filling level in the

priming tank, it must be connected to terminals 10 and 11.

• If status and alarm indications are to be transmitted to a

building management system, terminals 31 to 40 must be used

for this purpose.

11. Commissioning

11.1 Preparations before start-up

Before start-up the following have to be done:

1. Check that all screw connections are fitted securely.

2. Check that all pipes are installed correctly.

3. Check that all electrical connections inside and outside the

controller are correctly connected and fitted securely.

4. Check that all fuses in the control cabinet are switched on.

5. Check that all safety devices are installed.

6. Make sure that any storage tank and pump priming tank are

filled with enough water.

7. Set pressure values on the three pressure switches, see

pressure switch operating manual. The value of the pressure

switches for the main pump should be 0.5 bar higher than the

value of the pressure switch for the jockey pump.

11.2 Start-up

Warning

During electrical installation, make sure that the

power supply cannot be accidentally switched

on.

Warning

Start-up must be carried out by authorised

personnel. The control cabinet of the controller

must remain closed during start-up. Danger of

death through electric shock!.

Caution

The sprinkler pump is not allowed to run against

a closed valve as this may cause an

unacceptable temperature increase or the

formation of steam. This may cause damage to

the sprinkler pump.

Caution

Before switching on the extinguishing water

booster set it must be filled with water.

In case of dry running the main pump will not

stop.
