  • The error code is displayed as 0, 1, 2, 3, or 10.

RUN LED Light Blinking (0.5 seconds) & Temperature Not Changing

• The RTD module is corrected for its measurement circuit before it is delivered from the factory.
  • In this case, the module uses Yn.5.
    • Check Yn.5 that the module is set using the MapleLogic memory Monitor.
    • Check if the bit Yn.5 is used through the scan program or communication.

RUN LED Light Blinking (0.3 seconds) & Temperature Stops Around -250°c or -50°C
