Filling control relay in tanks with alarm by minimum level.
Protection of electric pumps against lack of water in tanks.
Timing adjustment (100 – 550 secs.) and Sensitivity 〔9 – 43〕/100 KΩ


  • Control of level in conductive liquids, through three probes (minimum, maximum and mass), with possibility of timing for the probe of minimum
  • Tank fill control
  • Protection against spillage in tanks
  • Sensitivity and timing adjustment


MODE A – Power the relay (green LED lights up – A.1)

The “S1” contact will arm when the liquid level reaches the lowest level of the probe (terminal 6) (the red led – “F.A.” No water).

The “S1” contact disarms when the liquid level reaches the maximum level of the probe (terminal 5) – switches off the red led – “F.A.” No water).
