ELECTRONIC REGULATOR For automatic electronic level measurement These automatic electronic regulators are mainly designed to start and to stop submerged or other types of pumps and, in general to break electric circuits directly or via electrovalves, for example. Three probes are in- stalled in the well or the tank and can be located up to 1,000 meters away from the control unit. This equipment also features "water shortage" protection and automatic tank refill. supply voltage: 220 V AC (110 V optional) MAIN CHARACTERISTICS • Probe voltage : 10 V under 1 mA max. current • Fluid resistance : 0 to 5.6 K ohms • Maximum distance between low- and high-level probes: 2 m, providing that drill 0 is under 100 mm » Probe material (low, high and common) : AISI 316 stainless • PVC solid wire, 1 mm2 area • Operating principle: Relay makes when all 3 probes are submerged and breaks when the fluid level reaches the lowest probe • Direct motor start under 5A - 270 V possible (without relay) • Tropicalized material • Types AT 5A & AT 5B: for mounting on octagonal plates • Types AT 10A, AT 1 OB & AT 20A: for panel mounting or instal- lation on DIN bars in a cabinet • These 3 models can also be mounted on walls or any other surface by means of 2 screws. • Types AT 5A, AT 1 OA & AT 20A standard sensitivity. Recom- mended to control submerged pumps, because they operate smoothly under high humidity and have outstanding operating reliability. Distance between control unit and probes can cover • Types AT 5B & AT 10B high sensitivity. Recommended for use in narrow drill holes where distance between high and low le- vel probes is over 2 m, and for use in slightly conductive fluids (organic solvents, hydrocarbons, food products, etc.) • Operating conditions: fluid resistance up to 70 K ohms Wiring diagrams DIRECT PUMP Position of contacts when the probes ate submerged ' Position of contacts when the probes are submerged DIRECT PUMP Position of contacts when the probes are submerged

DATA SHEET REGULASONDE ELECTRONIC REGULATOR For automatic electronic level measurement OPTIONAL ACCESSORIES PROBE ELECTRICAL CABLE Probe for electronic regulator Electrical cable for installation of probes Material Weignt Dimensions Maximum temperature DESCRIPTION The Regulasonde electronic regulator works with 3 or more probes (for AT100A) and allow level control of two or more levels (for AT100A). It’s important to know that the « common » probe must be placed at a lower level than the low level probe. It is important to highlight that when working in a tank or metal cistern, it is possible...
