4 Start-up
4.1 General
All electrical lines must have been installed properly before the start-up takes
place. All connections must be arranged so that there are no mechanical forces
acting on the device.
• Check that the defined safety measures for tank systems have been ob-
served.
• Check that the mechanical installation is correct in accordance with the ap-
plicable erection regulations for tank systems.
• Make sure that the device is protected from the effects of frost.
• Switch the supply voltage on. A small light diode flashes regularly and
briefly as a function control.
• This completes the start-up.
NOTICE! The probe was calibrated to the ordered installation dimension.
An on-site calibration is therefore unnecessary.
If for some reason a recalibration does become necessary, proceed as de-
scribed below.

Calibration
For the calibration, you need an infrared remote control of type EU04 (see ac-
cessories).

The calibration takes place in two stages:
1. Minimum filling level
w
Zero point calibration
1. Reduce the level in the tank to the lowest filling level.
2. Press and hold the "
MIN
" button.
Ê
The status LED flashes quickly. After 2 to 3 seconds, the LED lights up
permanently. This is how the device indicates that the zero point has
been stored.
3. Now release the button.
u
The zero point has been calibrated.
2. Maximum filling level

Calibration of the measurement range (end value)
1. Fill the tank to the highest filling level.
2. Press and hold the "
MAX
" button on the infrared remote control.
Ê
The status LED flashes quickly. After 2 to 3 seconds, the LED lights up
permanently. This is how the device indicates that the end value has
been stored.
3. Now release the button.
u
The end value has been calibrated.
u
The calibration process is complete.
