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).
The probe signal can be checked with menu step "22. Test Current"
At 0 cm fill level
approx. 3.7 – 4.3 mA.
In the event of a considerable deviation, we recommend a replacement.
New probe.
New probe/ replacement of the operating medium
If the installation of a new probe is required and/or a change in the operating medium takes
place, then firstly, all of the “standard values” under menu step “9th zero point probe“ must be
reset to the
factory setting
!
It is also necessary to check, and if required, correct all further set values.
MAINTENANCE
See FUNCTION CHECK.
RESTORATION
If the actions described in TROUBLESHOOTING do not lead to a proper restart and if there is
no dimensioning problem, the product must be sent to the manufacturer to be checked. 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

install if necessary.
