- activation of the fault signal and led pump fault.
- Hand reset of the fault (rotary switch on position 0 - reset).
A 0.5A level is fixed for detect no load on the phase supervised. This
function allows to protect against overload on 2 other phases when
the phase supervised is cut:
- activation of the fault signal and led pump fault.
- Hand reset of the fault (rotary switch on position 0 - reset).
For control box with thermal relay
The protection against motor overload and missing phase is operat-
ing by a thermal relay. When the thermal relay goes into fault, the
faulty pump is stopped and electronic switch directly to another
available pump:
- activation of the fault signal and led pump fault.
- Hand reset of the fault (rotary switch on position 0 - reset).
Installation leakage detection
(installation pipes breaking)
When the pressure delivered by the booster is lower than 20 % of
the low pressure setting more than 60 seconds, all the pumps are
stopped.
- activation of the fault signal.
- Err-prs mentioned on the display.
- Hand reset of the fault by positioning all the switches on 0 – reset.
Test of the pumps
Mode run test (dip switch run-test position ON, FIG. 3, pos. 4) :
Every 6 hour the device performs test on a different pump. Every
pump runs 15 seconds. At the end of each pump test, the system
checks that the installation pressure is really higher than the high
pressure setting and that the current consumption of the motor is
higher than 0.5A (not with thermal relay). If the test is negative for
one of the pumps, the fault Err-Tst is displayed and the device acti-
vates the fault signal. To cancel an operating test fault, position the
rotary switch of the defective pump on 0-reset.
Lack of water protection
The detection of lack of water will be temporized (20s). This function
is operative whatever the operating mode of the control box is.
Fault signal
The fault transfer is activated when one of the following fault
appears:
- missing phase (mains supply or motor).
- magnetic circuit breaking (except control box with thermal relay).
- motor overload.
- motor current lower than 0.5A (except control box with thermal
relay).
- lack of water.
- leakage in the installation.
- pressure transmitter cable cut.
- run test failure.
6.2.2 Inputs/Outputs - FIG. 4
1 Pressure input (4 – 20mA): an analog input on the electronic part
allows the connection of a pressure sensor 4-20mA.
2 Remote control (Ext. Off): the remote control (contact NC) allows
the full stop of the booster pumps, an input ON/OFF is dedicated
to this input.
3 Lack of water: a pressure switch (contact NO) or a float switch
protects the booster against lack of water, an input ON/OFF is
dedicated to this sensor.
This function is active whatever the operating mode of the con-
trol box is.
6 seconds are needed to start again the booster after closing
the contact (water back).
4 Fault signal (SSM): an output fitted with a potential free contact
(Normally Open; 250V ; 5A) allows the transfer of the booster
faults.
For control box with thermal relay
5 WSK Contact: contact WSK allows an external connection of
WSK (Klixon) from motor, an input ON/OFF is dedicated to this
input.
6 RUN Signal: an output fitted with a potential free contact
(Normally Open; 250V ; 5A) allows the transfer of the booster run-
ning.
6.2.3 Signalling - FIG. 2
Booster information
1 Power ON: mains voltage signalling (fixed yellow LED).
2 Lack of water: lack of water signalling (fixed red LED).
3 Display: Display 3x7 segments
Permanent display of real pressure of discharge network.
Blinking display when changing value settings:
- high pressure setting (PHi).
- low pressure setting (PLo).
- delay for base load pump stop (dtp).
- setting of the pressure sensor range (Sen).
Fault display:
- Err-Prs: pressure fault < 20% of the low pressure setting
- Err-Sen: pressure sensor cable cut.
- Err-Tst: run test fault of the pumps.
Information per pump
4 Pump ON: pump operating indication (fixed green LED in mode
Auto and a blinking LED in mode Hand).
5 Pump alarm: pump fault indication (red LED that blinks 5 sec-
onds during the fault detection and then remains as fixed).
- No motor consumption.
- Magnetic circuit-breaking (motor short circuit).
- Over current protection (motor overload).
7. INSTALLATION AND ELECTRICAL CONNECTION
7.1 Installation
The control boxes are directly assembled on the boosters.
7.2 Electrical connection
WARNING! The electrical connection must be made accord-
ing to the local regulations by an electrical installation engi-
neer approved by the local utility.
To make the electrical connection, the corresponding installation
and operating instructions and attached electrical circuit diagrams
must be observed. General points to be considered are listed
below:
- the type of current and voltage of the mains connection must
comply with the details on the type plate and the circuit diagram
of the control unit.
- as protection measure, the booster must be earthed according to
the regulations (i.e. according to the local regulations and circum-
stances) ; the connections intended for this purpose are identified
accordingly (see circuit diagram).
- all other measurements, settings, etc., are specified in the installa-
tion and operating instruction and on the electrical connection
diagram of the control box.
Power supply cable
The electric supply cable shall be correctly dimensioned according
to the total booster power (see type plate).
Connecting the control box on a voltage different from the one
mentioned in the description (see chapter 5.2. technical data) is not
possible.
NOTE: for any further details an electric diagram is available
inside the control box.
WARNING! Do not forget to connect the earth terminal!
Pump supply cable
ATTENTION! The installation and operating rules in the instruc-
tions of the pumps shall be observed!
The electric supply cable shall be correctly dimensioned according
to the total booster power (see type plate).
