Chapter 1 Start Here… Congratulations on your purchase of a Sondar Ultrasonic Level Meter 600 Series. This quality system has been developed over many years and represents the latest in high technology ultrasonic level measurement and control. It has been designed to give you years of trouble-free performance, and a few minutes spent reading this operating manual will ensure that your installation is as simple as possible.
About the SLM600 Series Functional Description The Sondar SLM600 Series is a highly developed ultrasonic level measurement system which provides non- contacting level measurement for a wide variety of applications in both liquids and solids. Easy calibration and maintenance free “fit and forget” performance mean that you can install the SLM600 Series rapidly and with confidence.
Product Specification Physical Dimensions overall 105 (dia). x 248.5 (height) mm electronics housing 105 (dia). x 172 (height) mm transducer housing 55 (dia) x 76.5 (height) mm mounting 2” NPT Weight Nominal 1 kg Case material/description Polypropylene Cable entry detail 1 x PG11 at rear (fitted with gland) Environmental IP Rating (electronics housing)
Chapter 2 Installation Power Supply Requirements The SLM600 operates from a DC supply of 20 –30V and will typically draw less than 0.08A. All electronic products are susceptible to electrostatic shock, so follow proper grounding procedures during installation. The compact one-piece construction of the SLM600 can be mounted easily using the integral nose thread (2”NPT).

Outdoor and Open Vessel Installation The SLM600 can be simply mounted on a bracket, suitable for the application and secured using the thread located at the top of the transducer (2”NPT). Care should be taken to ensure that the SLM600 is not installed in direct sunlight, in order to avoid errors in the measurement of ambient temperature.

Stand Pipe Installations When mounting the SLM600 to a standpipe care should be taken to ensure that the standpipe is of sufficient dia with reference to its length, see the table below for details: D(mm) Length(mm) L(mm) D(mm) When using a standpipe, fixed to the top of a vessel, ensure that the open end of the standpipe is clear of any obstructions such as weld seams, gaskets etc.
Cable Entry The SLM600 Series has a single PG9 cable entry, fitted with a suitable gland, to ensure moisture protection is maintained. Terminal Connection Details The SLM600 Series comes in both 2 wire and 3 wire versions the terminal connections for both are as detailed below.
There are no user serviceable parts inside your SLM600, if you experience any problems with the unit, then please contact IS Technologies Co., Ltd. for advice. To clean the equipment, wipe with a damp cloth. Do not use any solvents on the enclosure.
Chapter 3 How To Use SLM600 Series Operating the Controls Display Whilst in the Run Mode, the 3-digit LCD display will show the current level reading in centimetres, it will also display a flashing “0” when a fault condition (Loss Of Echo) is detected. When in the Program Mode the display is used to read information on the Menu Options and the values entered.
Program Mode This mode is used to set up the SLM600 or change information already set, this is achieved by using the 4 push buttons located either side of the display. Entering a value for each of the menu options that are relevant to your application provides all the programming information.
