INSTALLATION
MANUAL
Manual Pressure Adjustment
(Manual Operation - Only for version with a display)
If the supply voltage is cut off, after a reconnection of the supply voltage and by pressing the two arrow keys below
the display at the same time, the pressure regulator will change to “Manual operation” mode. This operating mode is
indicated in the display by the letters “HND”.
The letters “HND” in the display will disappear after the arrow keys are released. The output pressure is shown on the
display, followed by the letters “HND” at the top right of the display.
Using the arrow keys, the output pressure can be changed (left arrow key or arrow pointing down => reduce the
output pressure, right arrow key or arrow pointing up => increase the output pressure).
This operating mode can be exited by pressing both arrow keys at the same time or by briefly cutting off the supply
voltage.
Operating Modes
Shutoff:
If the setpoint is set to less than 0.5%, the air will be released from the valve and the current supplied to the exhaust
valve will be switched off after 10 seconds.
Over temperature:
If the internal control electronics reach a temperature above 100°C, the control function will be restricted in order to
prevent any more overheating.
