• 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 exceeds SP2, the output 2 provides a signal (upper value
exceeded, submersible pump ON).
• If the level is below SP3, the output 3 provides a signal (lower value
reached, submersible pump OFF).
