MC 315 ATEX Weight Indicator | PAVONE | Made in Italy
  • The use in areas with danger of explosion is safe thanks to the low energy used by the weight indicator and the low working temperatures. The power can be supplied by an AL-AX certified power supply or by an AL-BX certified battery power supply located in a safe area or inside an ATEX certified container for hazardous areas.

  • On the side of the instrument there is a square silver plate where you can find a list of the abbreviations of the ATEX regulation, the model of the instrument, the related options that are available (e.g. Fieldbus, Analog, etc.), the serial number and the voltage of supply.

  • On turning on the instrument by pressing the ON button for some seconds, you will be able to read the firmware code that is shown on the display. This code is essential in case you need assistance from one of our technicians.

  • MC315 provides two RS485 serial ports and, through the optical fiber connected to the external S318 module, it provides additional RS485 and RS232 serial ports, an analogue output and the main Fieldbuses on the market such as Profinet, Ethernet IP, etc.

Connections

  • By opening the weight instrument, we can see the motherboard where the terminal blocks for the connections are housed. Let's see them closely.
  • In the first terminal block you can find the 5 Vdc power supply and the two RS485 serial ports mounted directly on the board from left to right. The two RS485 are connected to two wires and allow to connect up to 32 instruments to a Master unit.
  • On the side you find the two connectors for the optical fiber with two different colors and a letter printed above to distinguish them:
    • grey connector with the letter R is the receiver
    • black connector with the letter T is the transmitter
  • To the right of the fiber connectors, you find the terminal block dedicated to the logic outputs. Starting from the first terminal, you find Output 1 up to Output 6 and lastly the common of all the outputs.
  • The logic outputs are connected to Photorelè and provide a clean contact. They also have an operating logic configurable from a special menu.
  • The next terminal block is the smallest and is dedicated to the two logic inputs: the first terminal is Input 1, the second Input 2 and the third the common. To activate a logic input, the voltage must be brought from 7 to 24 Vdc while the common must be connected with the negative of the same power supply.
  • The last terminal block is used to connect up to four 350Ω load cells simultaneously. The supply voltage of the load cells is 3.3 Vdc and is protected against temporary short circuit.
  • From left to right, the connection is as follows: - Exc, + Exc, + Sens, - Sens, - Signal, + Signal.
  • The cell screen must be connected to terminal 1.
  • The last two terminals are used for the second load cell in case of special software that includes the dual channel function.
  • The working range of the instrument is from -3.9 mV / V to 3.9 mV / V.
