Start of the learning function

First time activation

With this function Shuttle

learns if there are any distur-

bances in the well or tank that could appear as a true echo.

Disturbances can result from inlet pipes, the pump installa-

tion, a slanted bottom, etc.

Shuttle

stores the levels of the false echoes, which will

practically eliminate the chance of locking on a false echo.

Shuttle

will look for a maximum of 15 echos.

Shuttle

starts to investigate the tank / well for disturbances.

The investigation is ﬁnished when all segments in the bar

graph are lit.

Note: According to the number of disturbing elements,

this process may take several minutes.

Select the function with the arrow keys.

Note: Only this selection is available if the learning

function settings have been erased earlier or the

function has never been activated before.

In this example, Shuttle

has found two false echos

➀ (the inlet) and ➁ (from the

pump intallation) and also

the correct echo from the

bottom of the well / tank.

Select the level closest to

the correct level +/- 15 cm

(➂).

If none of the echoes are

from a true level meas-

urement, but are all false

echoes (e.g. a slanted well

bottom), select 'nf'

(= none found).

➀

➁

➂

Shuttle

now reverts to normal read-out.

Note: If 'nf'was selected as explained above, Shuttle

will normally indicate system error until a varying

echo from a true level surface is detected.
