System setup

The values corresponding to 4mA and 20mA must be adjusted in the menus 4042 and 4043.

Menu Description

Comments

404X

Water level nominal

This value corresponds to the 20mA value of the transducer.

404X

Water level minimum

This value corresponds to the 4mA value of the transducer.

This can be adjusted from the USW or from the display.

The 4mA value can be adjusted negative. This is to be able to stop the
regulation (see the description of ‘Water level regulation’ on page 10).
