HYDRAULIC CONNECTIONS

Before proceeding with hydraulic connection it is essential to install a non-return valve in every pump´s
inlet.
To achieve an installation with the best possible efficiency, both pumps should have the same electric
power.
The SPEEDMATIC SET ALT control device must be connected in vertical position (Fig.2), the inlet port (
1 ¼" male) directly to the main pump discharge and the outlet port ( 1 ¼" male) at the main network.

ELECTRIC CONNECTION

The manufacturer declines all responsibility in the event of accident or damage due to wrong electric
Use cords type H07RN-F with section enough to the power installed.
Power supply SPEEDMATIC SET ALT 21110: S > 1.5 mm .
Motor supply: S > 1 mm .
Check the power supply to be 220/240 V. Dismount the cover 1 of the electronic circuit and carry out
the connections according to the indications located on the connection strip base
Do the power supply connection (being sure there is a good earth connection): L1 N
connection by mean of magnetothermic switch in OFF mode.
The earth conductor must be longer than the others. It will be the first one to to be mounted during the
assembly and the last one to to be disconnected during the dismantling.
Do the pumps connection ~1x230 Vac.
Do the connection of auxiliary devices:
Alarm monitoring: the SPEEDMATIC SET ALT has a volt-free contact with 1 A of maximum
intensity for the transmission of diferent types of signal (optical, acoustics, etc) when detects
some failure that previously has been displayed in the LCD screen. For its connection to see Fig.
2.
Min. level control: there is an input for the stop of all the pumps as soon as is disconnected the
external switch of minimum level. See Fig. 2.
WARNING!. Wrong connections could spoil the electronic circuit.
STARTUP
Be sure that every pump is correctly primed.
Connect the SPEEDMATIC SET ALT to the electric supply with the magnetothermic switch, FAILURE led
light will be ON. Wait for 15 seconds while the SPEEDMATIC SET ALT is doing the autotest. Once it
finishes, led light FAILURE is OFF and led light LINE is ON. The LCD screen will show message
"SPEEDMATIC SET ALT " and inmediately the state display:
Verify if the MANUAL mode is activated (AUTOMATIC led light OFF). In case of being in AUTOMATIC go to
