ENGLISH
WARNING! Do not forget to connect the earth terminal!
Voltage selector - FIG. 5
ATTENTION! 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.
WARNING! Do not apply external voltage to the terminals!
Remote control signal
An input ON/OFF (FIG. 4, pos. 2) is dedicated to the remote control
(NC), it allows the full stop of the booster pumps.
The control box is delivery with a strap on this input.
This input is only operative for automatic mode.
Lack of water protection
An input ON/OFF (FIG. 4, pos. 3) protects the booster against lack of
water, a pressure switch (Normally Open) or a float switch shall be
connected to this input.
WARNING! Do not apply external voltage to the terminals!
Fault signal
A contact (Normally Open FIG. 4, pos. 4), free potential, to allow a
remote transfer of the alarms.
WARNING! A 250V maximum external electrical supply may
be connected on this contact. This dangerous voltage
remains inside even if main switch is off.
For control box with thermal relay
WSK
An input (FIG. 4, pos. 5) allows an external connection of WSK
(Klixon) from motor.
Run signal pump
A contact (NO, FIG. 4b, pos. 6), free potential, allows the remote
transfer of the pump running signal.
WARNING! A 250V maximum external electrical supply may
be connected on this contact. This dangerous voltage
remains inside even if main switch is off.
8. COMMISSIONING
We recommend that the booster is first commissioned by the SALM-
SON customer service. Ask your dealer, the nearest SALMSON agent
or contact our central customer service department.
Before switching on for the first time, check that the customer's
wiring has been done correctly, particularly the earthing.
ATTENTION!
Tighten all the supply terminals before starting the unit!
Check the position of the voltage selection strap before
switching on!
8.1 Rotation direction of the motors
Check the rotation direction of the pump complies with the direc-
tion shown by the arrow on the pump identification label. Use mode
"hand operation" to check.
- if all the pumps run in the wrong direction, reverse 2 of the phases
of the mains supply cable.
WARNING! Before changing over the phases, switch off the
installation main switch.
- if only one pump runs in the wrong direction in standard operat-
ing, change over 2 of the phases in the motor terminal box.
WARNING! Switch off the installation main switch before
changing over the phases.
8.2 Setting description
WARNING! For changing parameters, the control box must
be open and the installation main switch must be on!
Configuration under voltage must be made according to the local
regulations by a qualified person.
- Position all rotary switches on 0 – reset.
- Set the range of the pressure transmitter used with the poten-
tiometer (FIG. 3, pos. 3). The display shows the limit value being set.
- Set the high pressure detection limit with the potentiometer
(FIG. 1, pos. 5 "PHi"). The display shows the limit value being set.
- Set the low pressure detection limit with the potentiometer
(FIG. 1, pos. 6 "PLo"). The display shows the limit value being set.
This value shall always be at least 0.2 bars lower than the high
pressure detection limit for sensors 0 – 6 ; 0 – 10 ; 0 – 16 and 0 - 25
bars and 0.4 bars lower than the high pressure detection limit for
sensors 0 – 40 bars.
- The dip-switch (FIG. 3, pos. 5 "Ext.off") shall be positioned on "REM".
The position "FLUX" shall not be used.
- Set the delay for pump stop with the potentiometer
(FIG. 3, pos. 2). The display shows the limit value being set. The
value mentioned is the delay for stopping the main pump, it can
be set from 5s to 180s, it determines automatically and proportion-
ally the stop delay of the extra pumps from 3s to 30s.
- Set the current detection limit of each motor with dedicated
potentiometers (FIG. 1, pos. 7 "I>" or thermal relay) in positioning
the arrows on nominal current as mentioned on the motor name-
plate and add 10 % (for the thermal relay it is 0,58*In).
- The run test mode for all the booster pumps is available in the
control box. To activate this test, position the dedicated dipswitch
(FIG. 3, rep 4 "run-test") on " ON ", otherwise position the dipswitch
on "OFF".
9. MAINTENANCE
WARNING! Before performing any maintenance or repair,
switch off the main switch of the installation!
The control box shall be kept clean.
