a mechanical switch, e.g. a float switch, is to be connected, the line

monitoring must be deactivated because only the switching condi-

tions "open" or "closed" can be delivered.

When level switches VEGASWING/VEGAVIB/VEGAWAVE in two-wire

version are connected, a function test can be carried out. The test key

is recessed behind the front plate of the signal conditioning instru-

ment. Press the test key for at least one second with a suitable object

(screwdriver, pen, etc.).
Pushing the test key interrupts the circuit to the sensor and triggers a

restart of the sensor. The statuses fault signal, full signal (1.2 mA) and

empty signal (2.1 mA) are thus simulated. Check if a fault signal (red

signal lamp) is triggered when the test key is pressed and then a full

signal and subsequent empty signal (yellow signal lamp) after the key

is released. Please note that when line monitoring is deactivated, the

red signal lamp does not light up.
Note:

Keep in mind that downstream connected devices are activated dur-

ing the function test. This allows you to check the correct function of

the measuring system.

6.3 Function chart "Point level"

The following chart provides an overview of the switching conditions

depending on the set mode and the level.
Note:

The switching conditions in the tables are only valid if the mode

switch on the sensor is set to "Max.".
