DISPLAY/PRESSURE READINGS
The actual outlet pressure is displayed during normal operation. See „Parameters/Display“ section.
Other displays:
Hnd indicates that the Manual mode has been selected.
SOF Internal error of pressure control. Replace valve or contact our Product Support.
Err
Internal overflow.
AEr Autozero overflow. Contact our Product Support.
PUSHBUTTONS
To enter the Manual mode, press and hold both pushbuttons simultaneously during power up. "Hnd" appears in the display.
Use the UP button to increase the outlet pressure and the DOWN button to decrease it. The actual outlet pressure is
displayed.
Quick presses on the buttons allow you to make slight changes in the pressure rating.
Longer presses allow you to make quick pressure changes.
Press both pushbuttons simultaneously to exit the manual mode.
