    Before starting to work, you have to check the functioning and integrity of the system. § Check for visible defects on the AD375MA, this may or may not include any or all of the following mounting facilities, connectors and connections, mechanical parts, internal or external communication devices, power supplies or power supply lines, etc.

  • Page 6: Part I Introduction

    The AD375MA is a rugged, microprocessor-based, power-efficient shaft encoder for reliable and accurate water level measurement. The built-in digital technology determines the absolute water level from the reference level and the relative rotational movements at level increase or decrease.

    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.) External Power Even though the Shaft Encoder's have an internal lithium battery, the unit should only be operated if +12VDC (9.0V to...

  • Page 15: 4-20Ma Interface

    Operation 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. To conserve power, the data logger switches power to the 4-20mA circuit only when it wants to make a measurement.

  • Page 20: Part V Maintenance

    Maintenance 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.
