Function
The sensors are ultrasonic sensors that detect small or large gas bubbles depending on
the sensitivity level.
When the alarm of an external air sensor is enabled in UNICORN and air is detected, the
pumps pause and the text AIR is shown in red color in the Process Picture.
When the alarm of the external air sensor is disabled in UNICORN and air is detected,
the pumps continue but the text AIR is still shown in red in the Process Picture.
Four external air sensors can be connected to the system. Each sensor has a predefined
identity, 1, 2, 3 or 4, and must be connected in numerical order, see the separate instal-
lation instructions. Position the external air sensors depending on your goal, for example:
