SPEEDMATIC ALT
BEFORE INSTALLATION AND USE READ THE FOLLOWING INSTRUCTIONS CAREFULLY.
THE MANUFACTURER DECLINES ALL RESPONSIBILITY IN THE EVENT OF ACCIDENT OR DAMAGE DUE TO
NEGLIGENCE OR FAILURE TO OBSERVE THE INSTRUCTIONS DESCRIBED IN THIS MANUAL OR IN
CONDITIONS THAT DIFFERS FROM THOSE INDICATED ON THE DEVICE.
OPERATION
The
SPEEDMATIC ALT
pumps - single or 3-phase pumps - with an electronic system managed by a software responding to the rigorous requirements of
efficiency and safety of the most important builders of pumps. Both pumps are managed by the same inverter (frequency
converter) acting in alternated operating sequence - never simultaneously - in each operating cycle. This system guarantees the
supply in case of failure of one of the electric pumps and also increases its life utility. The type of pump, single phase or 3-phase it
is easily selected by configuration.
The system incorporates a LCD screen where the parameters configuration is very easy and intuitive. Once the configuration
parameters are introduced, the
SPEEDMATIC ALT
manages the start-up of the different system pumps and the 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 starting pressure of the pumps.
Example for a 5 floors building (15 m) with pumps placed at level 0:
Hm
=
15 m
@
1.5 bar
Pw
= 1,5 bar
Pc
=
15 x 0,033 bar
@
0,5 bar
Prmin
=
1,5 + 1,5 + 0,5 =
3,5 bar
