STARTUP (diagram C)
Before starting the device please read the pre-
vious sections, especially “Hydraulic Installation”
and “Electrical connection”.
Follow next steps:
1. Start the device by pressing .
2.
(only DGplus and DGM2)
Set the pump rated current intensity value:
- Press during 3 seconds.
- The current intensity value is displayed on screen
and LED A is flashing (factory setting 16A).
- By mean of and is adjusted the rated cu-
rrent reflected in the characteristics plate of the
motor. See Note 1.
- Press for validation.
3. Set the cut-in (start) pressure:
- Press during 3 seconds.
- The start pressure value is displayed on screen
and LED START is flashing.
- By mean of and is adjusted the start pressu-
re from 0,5 to 7 bar.
*If it is higher than 3 bar, it
is advisable to use a small expansion tank.
- Press for validation.
4. Set the cut-out pressure (only if it has been set on
ADVANCED MENU the pressure dependent operation
mode):
- Press during 3 seconds.
- The stop pressure value is displayed on screen
and LED STOP is flashing.
- By mean of and is adjusted the stop pressu-
re from 1 to 8 bar.
- Press for validation.
In pressure dependent mode is compulsory the
installation of a pneumatic tank.
5. The unit is ready to operate but more optional
adjustments can be set through basic and advanced
MENUS. See the next chapter.
Note 1: it is important to introduce exactly the
rated current specified on the nameplate of the
pump. If a new pump is installed this process
should be repeated.
