  • Page 3: Introduction

    HyQuest Solutions Pty. Ltd. 1. Introduction The Hyquest Solutions Absolute Shaft Encoder model AD375MA is a low power, microprocessor controlled shaft encoder designed for field operation to enable measurement of water level. The internal CMOS circuitry enables the encoder to output measured levels in absolute format as a 4-20mA and SDI-12 signal at the same time.

  • Page 4: Installation

    The encoder is readily adapted to float pulley wheels with beaded or borehole floatline, tape chain and sprockets and gear drives. Provided on the base of each encoder are two threaded holes for levelling screws. Model AD375MA Issue 3 July, 2017 Page 4...
  • Page 5 Float and counterweight should pass each other and should have adequate clearance from the sides of the Borehole. Model AD375MA Issue 3 July, 2017 Page 5...
  • Page 6 A +12V power source must be connected to the SDI-12 / Power port as shown on page 8, to provide power to the AD375MA electronics. Once external power is connected, press the “Scroll” button and step to the “Battery Voltage”...

  • Page 12: Maintenance

    HyQuest Solutions Pty. Ltd. 3. Maintenance The AD375MA (as well as AD37.5MA, AD150MA and AD100MA) Shaft Encoders require no maintenance, however all connected mechanical equipment should be periodically checked for cleanliness and ease of operation. Internal 3.6V Lithium AA batteries should be replaced every 2 years.
  • Page 13 Screwless Terminals The plug in terminal block shown is a screwless terminal that keeps a constant tension on the wire that is inserted. (The mating socket on the front panel of the AD375MA is sealed with a waterproofing gasket.) 1. Use a small flat blade screwdriver and push-in on the orange groove.
  • Page 14 HyQuest Solutions Pty. Ltd. 4-20mA Interface The 4-20mA interface in the AD375MA is optically isolated from the 0V and +12VDC on the right hand end of the connector. The 4-20mA circuitry must be powered by the loop. Batt +12V + 4-20mA...

  • Page 15: Lcd Screen

    There are 7 LCD screens available. Some screens display internal data and some allow parameters to be changed. The screens are: LCD SCREEN DESCRIPTION AD375MA S/W 5.1 Display model, S/W Rev and present river level Level: 9.392 m Battery Voltage Display internal and external battery voltage.
