    What to do if an input signal does not turn off on my Mitsubishi Electric QX80?
    • K
      Kevin EllisAug 22, 2025
      If an input signal on your Mitsubishi Electric Controller doesn't turn off, it could be due to a few reasons. One cause may be leakage current from the input switch. To resolve this, connect an appropriate resistor to ensure the voltage across the input module terminals is less than the off voltage. A CR constant of 0.1 to 0.47 F + 47 to 120? (1/2W) is recommended. Another cause could be driving the system with a limit switch that has a neon lamp. The solution is the same as above, or you could create an independent display circuit. Lastly, leakage current from the wiring cable's line capacity could be the problem. The solution is the same as the first example; however, leakage current is not generated when the power supply is located in the input equipment side.

      If the input signal of your Mitsubishi Electric Controller doesn't turn OFF, several factors could be the cause. Here are some potential solutions: * If the issue is due to leakage current from the input switch, connect an appropriate resistor to lower the voltage across the input module terminals below the OFF voltage value. A CR constant of 0.1 to 47 F + 47 to 120 (1/2W) is recommended. * If it's due to a limit switch with a neon lamp, apply the same solution as above or create an independent display circuit. * For leakage current from the wiring cable's line capacity, use the same resistor solution. Note that leakage current isn't generated when the power supply is on the input equipment side. * If using a switch with an LED indicator, connect a resistor to lower the voltage be...
