Test mode

The level probe can be changed to test mode at any time. With this it is easy to check the installation of
the level probe. In the test mode the analogue outputs will perform according to the diagrams below.
Activation Test Mode:
Connect the grey wire (ETW) with the supply voltage (+) and hold it > 18 seconds. During the test mode the
LED is flashing with 0,4 Hz frequency and the output pulsates accordingly.
With release of the grey wire (ETW) the test mode is stopped and the level probe returns to the previous
adjusted state.
