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.

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).
To start the sequence of configuration press MENU during 3"

By mean of keys pq we can choose the languages: "LANGUAGE ENGLISH", "LANGUE
FRANÇAISE", "LINGUA ITALIANA" and "IDIOMA ESPAÑOL".
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.
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.
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 pqto change NO by Y.
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.
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:
Input pressure: 2 bar.
n
Differential start: 0,3 bar
n
Final start pressure: 2 - 0,6 = 1,4 bar.

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.
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.
After pressing ENTER pushbutton, the system is ready to operate. Press AUTOMATIC
