What to do if an input signal does not turn off on my Mitsubishi Electric QX10-TS?

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.
