In case of group assembly, after pressing AUTOMATIC in the MASTER device, the AUTOMATIC LED LIGHT of the SLAVE device will
start to flash intermittently, indicating that communication between both devices is ready. If this does not happen verify the
connection (fig 5).
The SPEEDBOX is configured by default as
SINGLE
. In case of individual assembly just confirm
SINGLE
by pushing
ENTER
. In case of group assembly (M-S), we will choose respectively
SLAVE
and
MASTER
in each unit pushing
q
. In case of assembly of more than 2 devices, we will change
“SLAVE” by “SPEEDC” pushing
q
twice - see instructions of our station
SPEEDCENTER.
This will be the system operating pressure. Use keys
pq
for modify the initial value (2 bar).
WARNING ! The input pressure must be al least 1 bar lower than the maximum
pressure of the pumps.
NOTE
: In case of group assembly, all the system operates at the pressure set in the MASTER
device, so that the configuration of set pressure in the slave device is superfluous.
EXTERNAL LEVEL SENSOR
. If the installation does not have level probe press
ENTER
to validate NO.
If the installation has a level probe, use keys
pq
to change NO by Y.
The range of lecture of the pressure transmitter installed must be adjusted.
If the range is within 0-10 bar confirm by mean of
ENTER.
If the range is within 0-16 or 0-25 bar change it by mean of
pq
and then confirm
with
ENTER.
ROTATION SENSE
. Using the
START/STOP
pushbutton verify the rotation sense. By
mean of keys
pq
(0/1) we can change it. Press
ENTER
for validation.
MINIMUM FREQUENCY
. Using
p
we can increase the lower frequency value, within
15-48 Hz for 3-phase pumps and 30-48 Hz for single-phase pumps.
*The minimum frequency value will be used as frequency stop in installations where the
automatic detection of Speedbox do not act due to leaks in the system. See hydraulic
installation.
By mean of keys
pq
input the nominal current intensity value in A of the pump
enabling the thermal protection. This value is located over the characteristics plate of
the motor. Press
ENTER
for validation.
WARNING: this value is linked with the flow detection system, it is very
important to enter the exact current consumption indicated on the
nameplate.
By mean of keys
pq
we can choose the languages: “LANGUAGE ENGLISH”, “LANGUE
FRANÇAISE”, “LINGUA ITALIANA” and “IDIOMA ESPAÑOL”.
To start the sequence of configuration press
MENU
during 3”
CONFIGURATION.
Using
pq
we can change the values and press
ENTER
for validation. Whenever we want to quit the configuration
sequence press
MENU
. After every
ENTER
it will appears automatically the different screens that constitute the configuration sequence.

The default value is 0,5 bar. This value of pressure is substracted to the system setpoint, resulting the
final pressure to which the system will set in motion the pump when the hydraulic network has a
demand. Use keys pq to modify the initial value. It is recommended to maintain this value between
0,3 and 0,6 bar. Example:
n
Input pressure: 2 bar.
n
Differential start: 0,3 bar
n
Final start pressure: 2 - 0,6 = 1,4 bar.
