      ATV320 drive

      Environment:
      All 

      Cause:
      LI6 status is not showing up on register 5202 logic input status.

      Updating Firmware on Obsolete 16 bit SCADAPacks (including SCADAPack Plus, SCADAPack Light and Micro 16 controllers)

      This Technical Note describes the hardware requirements for updating firmware on obsolete SCADAPack models that include the 5203 & 5204 CPU boards (SCADAPacks from 2004 and earlier). The 5203 contains 2 RS-232 communication ports and the 5204 contains 1 RS-485 port and 1 RS-232 communication port. Both hardware boards where manufactured as part of SCADAPack, SCADAPack Light, SCADPack Plus and Micro 16 models.
       

      Board Layout

      Older versions of the 5203/5204 board has a place for 4 40-pin integrated circuits. These are labelled as U13, U14, U15 and U10 from left to right. There are also 2 jumper pins J3 and J4. These components determine the flash and RAM that is currently installed on the SCADAPack. In order to update the firmware on a 5203/5204 board to the latest released version, the SCADAPack must have 1024 bytes of RAM (OS & APP) installed.


       

      Determining Installed RAM

      U15 & U10 along with the jumper pins J3 and J4 determine how much RAM is installed. These chips can range from 128K - 512k each. Refer to to the table below to determine how much RAM is installed.
       
      Total RAM OS RAM (U10) Jumper J4 APP RAM (U15) Jumper J3
      256k 128k Right 128k Right
      640k 128k Right 512k Left
      1024k 512k Left 512k Left
      512k 512k Left 0 Left
      640k 512k Left 128k Right

      If jumpers J3 and J4 are currently in the "Right" position, then you will need to update one or both of the RAM chips in U15 and U10. Contact your Schneider Electric Telemetrey & Remote SCADA Solutions Sales representative for part numbers and pricing or email SalesTRSS@Schneider-Electric.com
       

      Firmware vs. Installed RAM

      If the RAM installed is less than 1024K (i.e. anything but 1024k), then firmware version 1.65 is the highest that can run on the controller. Please contact Technical Support at trss-support@schneider-electric.com to obtain firmware version 1.65.

      If you are updating a SCADAPack with the latest version of Realflo, IEC-61131 programming environment or simply updating the firmware, then ensure you have both U15 and U10 chips installed and they are both 512K


       

      How can EM422EM-E-KBTS and EM422EM-E-KMTS be used for three phase monitoring?

      For three-phase installations, two additional sensors are required.
      EM422S-12C190A: Clamp-type sensor, suitable for 90A cables up to 12mm diameter.
      EM422S-16C120A: Clamp-type sensor, suitable for 120A cables up to 16mm diameter.

      Can EM422EM-E-KMTS or EM422EM-E-KBTS measure three phase ?

      In three-phase installations, two additional sensors may be required.

      Ecomind Sensors that can be purchased separately:
      EM422S-12C90A: Clamp-type sensor, suitable for 90A cables up to 12mm diameter.
      EM422S-16C120A: Clamp-type sensor, suitable for 120A cables up to 16mm diameter.
