SPEEDMATIC 1305-1309
OPERATION
SPEEDMATIC is a compact automatic control device designed for the 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 builders of pumps. 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 a LCD screen where the parameters configuration is very easy and intuitive. Once the
configuration parameters are introduced, the SPEEDMATIC 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 ideal
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 SPEEDMATIC MASTER - responsible of the
group´s control - and a SPEEDMATIC configured as SLAVE controlled by the master device.
Due to the alternating sequence of operation, the SPEEDMATIC 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 work alternately as SECONDARY device.

n
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
n
against over-intensities, the ART tries to connect the pump, with a programmed periodicity because the water
supply could have been restored

against dry operation.
Mode MASTER&SLAVE. Communication with another device SPEEDMATIC to operate in group.
n
For environment temperatures under 0ºC it is very important to take measures to avoid water freezing.
Register of operational controls: infomation about operating hours, counter of starts, counter of connections to the
