• If the level is below SP1, output 1 switches. If SP1 is exceeded or if
there is a wire break, output 1 switches off (alarm).
• If the level reaches SP2, the output 2 provides a signal (upper preset
value reached, finish refilling).
• If the level is below SP3, the output 3 provides a signal (below lower
preset value, start refilling).
• If the level is above SP4, the output is switched. If the level is below
SP4 or if there is a wire break, output 4 switches off (alarm message
"below min. value/wire break").
