Test procedure with VEGAVIB/VEGAWAVE
Pushing the test key interrupts the circuit to the sensor and triggers
a restart of the sensor. In the process, the conditions fault signal, full
alarm (< 1 mA) and empty alarm (> 2.2 mA) are simulated one after
the other. Check if a fault signal is triggered when you push the test
key (red LED lights). The red LED does not light up when line monitor-
ing is deactivated.
After the test key is released, the sensor is again supplied with
voltage. During the warm-up phase of the sensor, the current briefly
increases, which can energize the relay and the yellow LED. This is
not relevant for the test assessment.
Once the sensor is ready for operation, a full alarm is simulated for
approx. 3 s, the yellow LED does not light and the relay is deener-
gized. For a positive test assessment, the time must be between 2 s
and 4 s. ①
Finally, an empty alarm is simulated by the sensor for approx. 1.5 s.
The yellow LED lights and the relay is energized. For a positive test
assessment, this time must be at least 1 s. ②
The test procedure is now finished, LED and relay return to the actual
operating condition. ③

Test process with VEGASWING
Pressing the test button interrupts the circuit to the sensor and
thereby initiates a restart of the sensor. This only simulates a fault
signal. Check whether the fault signal occurs when the test button is
pressed (red LED lights up). If the line monitoring is deactivated, the
red LED does not light up.
After releasing the test button, the sensor is supplied with voltage
again. After that, if the function is correct, the red fault LED must no
longer light up and the relays are energised or de-energised depend-
ing on the state of the sensor.
