Lack of water protection
The detection of lack of water will be temporised (10s). This function
is operative whatever the operating mode of the control box is.
- ctivation of the fault signal, the fault for burner and LED lack of
water".
- utomatic reset of the fault.
Fault signal
The fault transfer is activated when one of the following fault
appears:
- Missing phase motor.
- Magnetic circuit breaking (except control box with thermal relay).
- Motor overload.
- Motor current lower than 0.5 (except control box with thermal
relay).
- Lack of water.
- Too high pressure.
- Too low pressure.
- Leakage in the installation.
- Pressure transmitter cable cut.
Fault signal of burner
The fault transfer for burner is activated when one of the following
faults appears:
- Lack of water
- Too high pressure
- Too low pressure
- Pressure transmitter cable cut.
6.2.2 Inputs/Outputs - FIG. 4
1 Pressure input (4 – 20m ): an analog input on the electronic part
allows the connection of a pressure sensor 4-20m .
2 Lack of water (Lack of water): a pressure switch (contact NO) or
a float switch protects the system against lack of water, an input
ON/OFF is dedicated to this sensor.
This function is active whatever the operating mode of the
control box is. 6 seconds are needed to start again the system
after closing the contact (water back).
3 Filling: float switch allow the filling of tank.
4 Fault signal (SSM): an output fitted with a potential free contact
(Normally Open; 250V ; 5 ) allows the transfer of the system
faults.
5 Fault signal for Burner (SBM Burner): an output fitted with a
potential free contact (Normally Open; 250V ; 5 ) allows the
transfer of the system Faults to stop burner (High pressure alarm,
Low pressure alarm, lack of water and sensor error).
6 Fault signal dry (SBM Dry): an output fitted with a potential free
contact (Normally Open; 250V ; 5 ) allows the transfer of lack of
water default.
7 Electrovalves : n output 24V C allow the filling electrovalve
management.
6.2.3 Signalling - FIG. 2
System 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-LE : pressure fault < 20% of the low pressure setting.
- Err-Sen: pressure sensor cable cut.
Information per pump
4 Pump ON: pump operating indication (fixed green LED in mode
uto 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).
Information for filling
7 Filling ON: electrovalve operating indication (fixed green LED in
mode uto and a blinking LED in mode Hand).
Information for fault
9 Too high pressure: too high pressure fault indication.
10 Too low pressure: too low pressure fault indication.
7. INST LL TION ND ELECTRIC L CONNECTION
7.1 Installation
The control boxes are directly assembled on the system.
7.2 Electrical connection
W RNING! 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 system 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).
Power supply cable
The electric supply cable shall be correctly dimensioned according
to the total system 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.
W RNING! Do not forget to connect the earth terminal!
Pump supply cable
W RNING! 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).
W RNING! Do not forget to connect the earth terminal!
Voltage selector - FIG. 5
TTENTION! Check the voltage selected before first starting!
Position the voltage selection strap of the safety transformer in rela-
tion to the supply voltage:
- supply 230V: strap positioned on mark 230V
- supply 400V: strap positioned on mark 400V
Pressure sensor
Right connecting of the sensor to the terminals (FIG. 4, pos. 1)
according to the control box electric diagram:
- The sensor supply is connected to the terminal +24V.
- The sensor output is connected to the terminal In.
Use a shielded cable, connect one side of the shield to the earth
terminals of the control box.
W RNING! Do not apply external voltage to the terminals!
