SPEEDMATIC 1314 - 1307 - 1314 MASTER - 1307 MASTER
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.
CLASSIFICATION AND TYPE
According to EN-60730-1 the SPEEDMATIC is a device of independent assembly, type 1B with software of class A.
Control circuir for an alternate current motor with cos
Class of disconnection 1Y (electronic disconnection).
MAIN CHARACTERISTICS
n
DN inlet port G2" male and DN outlet port G2" Female.
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
against over-intensities, the
supply could have been restored
n
Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC mode keeping
the configuration parameters (see "CONFIGURATION" chapter).
n
Inside pressure transducer.
n
Volt-free contact for monitoring the alarms displayed in screen originated by irregularities or problems of the
system.
n
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
APP function ( Adaptability to the peaks of pressure). The system analyzes periodically the elasticity of the
hydraulic net, allowing to work the SPEEDMATIC with or without expansion tank and without modifying internal
parameters of the device. Nevertheless, is highly recommended their use, in order of getting a better pressure
stability.
n
Connections for detection of minimum water level in aspiration tank. This system is independent of the safety
against dry operation. Is optional.
n
Mode MASTER&SLAVE. Communication with another device SPEEDMATIC to operate in group.
n
AIS function (Anti-Ice System). If temperatures under 5 ºC are detected it will start periodically the pump avoiding the
freezing of the water inside the pump.
For environment temperatures under 0ºC it is very important to take measures to avoid water freezing.
n
Register of operational controls: infomation about operating hours, counter of starts, counter of connections to the
power supply.
n
Register of alarms: information about type and number of alarms since the starting up of the device.
