FUNCTION CHECK
We recommend that you check the displayed litre values once per year to make sure that they
are correct.
For a simple check, pull the level probe up by its cable so that it hangs above the liquid.
In this status the display device should show 0 litres (+ tolerance).
Checking the level probe signal can be checked through menu item 22:
At 0 cm fill level approx. 3,7 - 4,3 mA
If the deviation is greater, we recommend an offset comparison of the probe, see device
menu "9.Offset probe" and, if necessary, adjustment via "10.Trim height".
New level probe:
If a new level probe has to be installed, first reset the system to the "default values" in
"9.Offset probe".
REPAIRS
If the measures explained above under TROUBLESHOOTING do not result in regular
START-UP, and if there is no dimensioning problem, the product must be sent to the
manufacturer for a check. Our warranty does not apply in cases of unauthorised interference.
If there are continuous fault messages or alarms (only with SmartBox
alarm level on the probe being reached or being undercut, check the connection line between
the signal part and the level probe to see whether it is interrupted or there is a short circuit; re-
install if necessary.
