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.

it is delayed the start in order to protect
the pump.
- rc2: alarm is activated and the pump is stop-

Remark 3:
By choosing “no” (normally open) it will operate as an auxiliary
pressure control element in the suction of the pump. It will restart
when the suction pressure reaches the configured PStart.
Example:
- PStop: 0,9 bar
- PStart: 1,2 bar
