    User’s & Technical Manual – ANALOG LIQUID LEVEL SENSOR ALLS6000 CONTROL UNIT ALLS6000 The ALLS6000 is a complete unit with built-in electric connection terminals, electronic board, air flow regulator, adjusting level knobs, a calibration button and air pipe connectors, in light green box, suitable for electronic devices, and DIN rail mounting.
  • Page 12 10 The unit must not be installed in height lower than the (HL). AIR PIPE CONNECTIONS At the bottom of the ALLS6000 there are 2 pipe connectors of 4-6 mm. Polyurethane or nylon pipes are suitable for these connectors.
  • Page 13 3-4 bubbles/sec. AIR GAUGE SENSOR The ALLS6000 has a single, monolithic silicon diaphragm, piezoresistive strain gauge sensor chip, providing a highly accurate and linear output directly proportional to the applied pressure. On-Chip Temperature Compensated & Calibrated, this Silicon Pressure Sensor is laser trimmed for precise span and offset, bias equalized with the Atmospheric pressure.

  • Page 14: Electrical Section

    ANALOG LIQUID LEVEL SENSOR ALLS6000 ELECTRICAL SECTION POWER SUPPLY (Terminals #4 - #5) The ALLS6000 includes an integrated power supply circuit. The maximum power consumption is approximately 0.5W in total operation, with all indicators and relay activated. Connect the power source with the terminals (4) and (5). The polarity is not important, as the internal power circuit includes electronic components for non-polarity connection.

  • Page 16: Operating Philosophy - Level Description

    ANALOG LIQUID LEVEL SENSOR ALLS6000 10. OPERATING PHILOSOPHY – LEVEL DESCRIPTION The ALLS6000 operating philosophy is based on a desirable working region and four critical liquid levels (fig. 14), which can be calibrated from the user to meet his application needs. The levels and their functionality are described below.
  • Page 17 User’s & Technical Manual – ANALOG LIQUID LEVEL SENSOR ALLS6000 The user can program the (DL) at a desirable level following the calibration process, without changing the other two level values. The Differential Level (DL) you select each time is stored in the unit’s memory as a percentage of (HL).
  • Page 18 Notice that with these example’s steps, for every (TL) you select with the potentiometer, the (DL) will be 12,5% less. PRESELECTED VALUES The standard version ALLS6000-S1 can control the liquid level in tanks with height from 10cm to 100cm and has the below preselected values and parameters. ...
