•  If the level is below SP1, the output is switched� If the level is above SP1 or if 

there is a wire break, output 1 switches OFF (alarm message "overflow / wire 

break")�

•  If the level reaches SP2, output 2 switches (upper preset value reached; finish 

refilling)�

•  If the level is below SP3, output 3 switches (below lower preset value; start 

refilling)�

•  If the level is below 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")�
