SPEEDBOX
BEFORE INSTALLATION AND USE READ THE FOLLOWING INSTRUCTIONS CAREFULLY. THE MANUFACTURER DECLINES ALL RESPONSABILITY IN THE
EVENT OF ACCIDENT OR DAMAGE DUE TO NEGLIGENCE OR FAILURE TO OBSERVE THE INSTRUCTIONS DESCRIBED IN THIS MANUAL OR IN
CONDITIONS THAT DIFFER FROM THOSE INDICATED ON THE DEVICE.
OPERATION
SPEEDBOX is a wall-mounted automatic control device designed for the single and three-phase pump´s automation, with an
electronic system managed by a software responding to the rigorous requirements of efficiency and safety of the most
important pump manufacturers. It includes a frequency inverter that regulates the speed of the pump in order to keep
constant the pressure independently of the flow given.
The system incorporates an LCD screen where the parameters configuration is very Speedbox and intuitive. Once the
configuration parameters are set, the SPEEDBOX manages the start-up of the pump and the frequency inverter. It assures a
constant pressure and an important costs reduction because at any time the control will feed the system with the right and
necessary output, obtaining a maximum energetic efficiency. In order to establish the optimal pressure in the installation is
suitable to consider following criteria:
Hm: Max. water column height in m. It depends on the number of floors and it corresponds to the height from the pump to the
last floor. Every 10 m of height corresponds approximately to 1 bar (0.98) bar.
Pw: Available minimum pressure in last floor (usually 1.5 bar).
Pc: Pressure drop. It can be considered with a simplified criteria as 0.033 bar/m.
Prmin: Minimum resultant pressure. It is the sum of the previous pressures and it will be the operating pressure of the pump.
Example for a 5 floors building (15 m) with pump placed at level 0:
Hm =15 m @ 1.5 bar Pw = 1,5 bar

MASTER AND SLAVE OPERATION
The group MASTER-SLAVE is constituted by a device configured as SPEEDBOX MASTER - responsible of the group´s control -
and an SPEEDBOX configured as SLAVE controlled by the master device.
Due to the alternating sequence of operation, the SPEEDBOX configured as MASTER began the first cycle as MAIN device - its
pump is the first to start - but in the next cycle it becomes SECONDARY - its pump is the second to start - and so on.
Therefore, the fact that a device is configured as MASTER involves control of the group but this fact does not avoid its operation
alternately as SECONDARY device. Each Speedbox must be provided with its own pressure transmitter.

MAIN CHARACTERISTICS

Wall-mounted frequency inverter for the pump control.
n
Control and safety system against over-intensities.
n
Control and safety system against dry operation.
n
ART function (Automatic Reset Test). If the device has been stopped due to the action of the safety system against over-
n
current, the ART tries to connect the pump, with a programmed periodicity because the water supply could have been
restored
Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC mode keeping the
n
configuration parameters (see "CONFIGURATION" chapter).
External pressure transducer (4..20 mA) under demand.

M
Possibility of communication with another device Speedbox to operate in MASTER & SLAVE regime.
Control panel (Fig.1):
n
LCD screen, for alarm menu with permanent pressure indication.
n
START/STOP push-button to act by hand each one of the pumps
n
ENTER pushbutton to save data in memory.
n
ON/OFF pushbutton to change rom AUTOMATIC to MANUAL mode or vice versa.
n
MENU push-button
n
Keyboard for the access to programming menu.
n
Digital gauge.
n
Connections for detection of minimum water level in aspiration tank. This system is independent of the safety against dry
n
operation. Is optional.
Register of operational controls: infomation about operating hours, counter of starts, counter of connections to the power
n
supply.
Register of alarms: information about type and number of alarms since the starting up of the device.
