Diehl Hydrus - Optical Pushbutton Functions

An optical pushbutton (see item 12) is positioned on the front panel of the
HYDRUS. By using the pushbutton the individual display loops are shown.
To save battery life, the display turns o if no control actions are taken for
4 minutes. By pressing the optical pushbutton the display becomes active
again and the current status appears in the display for about 2 seconds.
If there is a fault, an error message appears, E -- 7 -- A (air in the pipe),
for example.
