3 function chart, Green = relay energized, Red = relay deenergized – VEGA VEGAVIB 55 - double relay (DPDT) User Manual
Page 19: Red (flashing) = failure

according to the "Function chart" (max. - max. detection or
overfill protection, min. - min. detection or dry run protection).
We recommend connecting according to the quiescent current
principle (replay contact deenergizes when reaching the
switching point), because the relay takes on the same (safe)
condition if a failure is detected.
Control lamp for indication of the switching condition.
