Level control relay for tank filling, with indication of “High Level”, “Lack of Water”, “Pump in Service” and “Thermal Shooting”.
The indications and how the level control relay for tank filling reacts (gun and disarm), allows protection against spillage in deposits and against lack of water. In addition, being a modular DIN-rail relay simplifies its installation. Advantage over 11-pin relays that require their docking station. Not only can it be used in standard electric switchboxes, it can also be used in modular boxes.
- Control of level in conductive liquids, through three probes (minimum, maximum and mass), with maximum level protection. Protection against spillage in deposits.
- Control of filling in tanks.
- Alarm by minimum level. Protection against lack of water in tanks.
- Indication of “Pump in Service” and “Thermal Shooting”.
Power the relay ( green led light on – A.1)
The “S1” contact will arm when the liquid level reaches the upper level probe (terminal S) (green LED lights up – “N.A.” high level).
The “S1” contact disarms when the liquid level drops below the lower level of the probe (terminal I) – turns off the green LED “N.A.” and lights red LED “F.A.” (lack of water).
