STARTUP
Before starting the device please read the previous sections, espe-
cially “Hydraulic Installation” and “Electrical connection”.
Follow next steps:
1. Set the power supply voltage.
- Press
during 3 seconds.
- The voltage value is displayed on screen, LED V lights up and display
is flashing.
- By mean of and is adjusted the power supply voltage. See
Note 1.
- Press for validation.
2. Set the pump rated current intensity value.
- Press during 3 seconds.
- The current intensity value is displayed on screen, LED A lights up and
display is flashing.
- By mean of and
is adjusted the rated current reflected in the
characteristics plate of the motor. See Note 2.
- Press for validation.
3. Start the device by pressing .
4. Set the cut-in (start) pressure:
- Press during 3 seconds.
- The start pressure value is displayed on screen, LED START lights up
and display is flashing.
- By mean of and is adjusted the start pressure from 0,5 to 11,5
bar
(+ version=11 bar)
.
- Press for validation.
5. Set the cut-out (stop) pressure:
- Press during 3 seconds.
- The stop pressure value is displayed on screen, LED STOP lights up
and display is flashing.
- By mean of and is adjusted the stop pressure from 1 to 12 bar
(+ version=12 bar)
.
- Press for validation.
6. The unit is ready to operate but more optional adjustments can be set
through basic and advanced MENUS. See the next chapter.
Remark 1: it is important to introduce exactly the power supply
voltage specified on the nameplate of the pump.
Remark 2: it is important to introduce exactly the rated current
specified on the nameplate of the pump.
