Display layout

1. When switched on the display will show an arrow symbol in the top right corner equivalent to the active navigation buttons on the control board.
   The arrows illustrate that it is possible to scroll up and down between the menus. Scrolling to the right makes it possible to enter a value. Set the value scrolling up (+) or down (-) to set the value higher or lower accordingly. Confirm by pressing ok.

2. A letter combination for easy reference in connection with service work will appear in the top right corner of the display.

Modes

3.1 Power On
The very first time the unit is switched on, we recommend setting the date and time in the Setup menu, settings, and display EP. If the date and time is not set, date and time will count from the pre-set default date and time.

Set date and time using navigation buttons.

Confirm by pressing OK button.

3.2 Standby
The start-up display will look as the one below.

Display for SB model with High- and Low-pressure – Select either HP or LP using arrows up & down.
3.3 Run Mode
3.3.1 Single Booster with high and low pressure
The following screen displays will appear when the unit is in Run Mode. Screen display for High-pressure unit in Run Mode. Scroll down to return to STANDARD pressure. Screen display STANDARD pressure. Scroll up to choose HP and scroll down to choose LP.

Screen display for Low-Pressure unit in Run Mode. Scroll up to return to STANDARD pressure.
Please note that you will remain in HIGH or LOW-pressure Run Mode until otherwise is selected.
3.4 Power Off

When the unit is off the display will only show a small dot in the top right corner.
In Off mode, it is possible to access all menus without the pump running by pressing the OK button on the panel.
Dot is equivalent to the OK confirm button on the panel.
3.5 Error/Warning

In case of an error, “ ERROR” will appear on the display screen.
Press the OFF button to switch of the unit.
If the error remains when the unit is switched ON again, please Press the right arrow to see the current error.
In case of a warning, “WARNING” will appear on the display screen. When a warning is detected the machine will either stop or run with limited performance until the cause of the warning has been improved (eg. inlet pressure). To see a further error/warning list and possible causes and remedies go to section 5.2.
