    ➢ When connecting this product to a measuring instrument, connect the shield wire of the output cable to the ground earth for the MS-95S. Noise may be included in the measurement data. ➢ Although this product is tested to meet EMC Directive compliance requirements, it may not fully satisfy...

  • Page 7: Signal Cable

    This product supports communication through the RS485 Modbus RTU. ➢ It is recommended to use the optional EKO converter cable when connecting the MS-95S to a PC. ➢ Depending on the USB-RS485 converter type, an additional termination resistor (120Ω) and/or pull- up/pull-down resistor (680Ω) is required for proper communication.
  • Page 8 EKO developed the MS-95S as an alternative. With an optical sensor design built around a new fisheye lens that observes the sky in 180°, the MS-95S employs a unique method to distinguish and record direct beam radiation from total sky radiation.
  • Page 9 In addition, because of seasonal variations in solar altitude, some sensors require data correction throughout the year. In contrast, the MS-95S is equipped with a fisheye lens with a viewing angle of 180°, allowing it to collect solar radiation from the entire sky. As a result, the solar radiation entering the sensor is contained within a single field of view.
  • Page 10 With multiple smart interfaces, the MS-95S can be used in applications in various fields such as agriculture, industry, construction, medicine, and solar energy. The digital output Modbus RTU / SDI-12 can be used in multi- sensor networks for on-site monitoring of large measurement systems.

    3. Sun Screen, Body The MS-95S have a sun screen to prevent any excessive body temperature increase generated by direct sun light. Weather resistant metals are used to reduce the effects and degradation caused by heat radiation, rain, and windblown dusts.
  • Page 13 Durable materials are used for the cable and connector, and pin terminals are attached at the end of the cable for easy connection with a data logger terminal block. * If longer cables, round terminals or fork terminals are required, please contact EKO Instruments or your distributor. [Also see [7. Specification, 7-4. Accessories List] for optional items.] The connector should be protected by the self-fusing tape when the sunshine duration sensor is used in areas with a risk of salt damage.

  • Page 14: Installation

    The sun screen can be removed by loosening the knurling screw and sliding it towards the spirit level direction. *When carrying the MS-95S with a sun screen attached, always hold the instrument from the bottom. Holding only the sun screen may lead to dropping the sensor as it comes off from the sun screen.

    2. Wiring Procedure Connect the output cable to the MS-95S: Insert the output cable into the connector port on the back of the sensor unit, and twist clockwise to fasten it. Make sure to tighten the connector all the way.
  • Page 17 5- 4. Co nn ec ti o ns The MS-95S is based on a digital Smart processing interface providing advanced measurement functions with 4 different industrial signal outputs (Modbus RTU, configurable SDI-12, 4-20mA and 0-1V with external shunt resistor 100Ω).
  • Page 18 The MS-95S has two analog outputs (4-20mA and 0-1V). The 4-20mA output is default, the 0-1V(0-10mA) output can be enabled through the ‘Hibi’ software which can be downloaded from the EKO website (MS-95S product page). See appendix A-1 to change the current output settings. The current output can be converted into a voltage output when a shunt resistor is used in series.
  • Page 19 The current output can be converted into a voltage output when a shunt resistor is used in series. The default output is 4-20mA. The 0-10mA (0-1V) output is disabled. The settings can be changed when the MS-95S is connected to a PC through the Hibi software, see appendix A-1 for instructions.
  • Page 20 2. Digital Output (Modbus RTU / SDI-12) The MS-95S can work in two digital output modes, respectively Modbus RTU and SDI-12. Modbus RTU output is set to default, SDI-12 output can be selected through the Hibi software. PC Connection (Modbus RTU) ➢...

  • Page 23 Figure 5-9. How to connect the MS-95S (SDI-12) The MS-95S can be configured within a multi sensor SDI-12 communication network. Up to 20 units of S- series sensors can be connected and be assigned with a unique address (*). For a multi sensor network the sensors need to be configured according to the recommended SDI-12 configuration standards as shown in figure 5-10.

    In this case, Appendix A-2 or A-3 communication format must be supported and programming is required. If only one MS-95S is connected, Hibi software can be installed on a PC for measurement setup and data acquisition. With the optional EKO converter cable, operation is possible simply by connecting the PC and MS-95S via USB.
