Loading...What to do if there is an invalid value in offset/gain setting and the error channel number cannot be identified on Mitsubishi Controller?
Perform the offset/gain setting again for all of the channels that use the user range settings. If the error occurs again, the module may be malfunctioning. Please consult your local Mitsubishi representative, explaining a detailed description of the problem.
What to do if I encounter a hardware error of the module in Mitsubishi I/O Systems?
To resolve a hardware error with your Mitsubishi I/O Systems module, first, switch the power off and then on again. If the error persists after this, it may indicate a module failure. In such a case, it's recommended to consult with the Mitsubishi office for further assistance.
How to solve scaling lower limit value equal to or greater than the scaling upper limit value on Mitsubishi Controller?
Set CH scaling upper/lower limit value so that the scaling upper limit value is greater than the scaling lower limit value.
What to do if the channel where no thermocouple is connected is set to conversion enable in Mitsubishi I/O Systems?
If the channel where no thermocouple is connected is set to conversion enable, check the channels which are set to conversion enable and the channels where thermocouples are connected, and set to conversion enable correctly.
What to do if wire disconnection of the cold junction temperature compensation resistor (RTD) is detected in Mitsubishi I/O Systems?
If a wire disconnection of the cold junction temperature compensation resistor (RTD) is detected, check the wiring status of the cold junction temperature compensation resistor (RTD).
What to do if conversion is made with another thermocouple set after setting of the offset/gain value in Mitsubishi I/O Systems?
If conversion is made with another thermocouple set after setting of the offset/gain value, make offset/gain setting again after changing the thermocouple.
How to fix moving average count setting value issues in Mitsubishi I/O Systems?
To correct the moving average count setting value, reset it to within the range of 2 to 60 times.
Why is the RUN LED flashing or off on my Mitsubishi Controller?
The RUN LED might be flashing or turned off if the mode is set to the offset/gain setting mode. Reset switch 4 of the intelligent function module switch setting for GX Developer to the normal mode.
Why is the ERR LED on or flashing on my Mitsubishi Controller?
The ERR LED on your Mitsubishi Controller may be lit or flashing because: - An error is being generated. Confirm the error code and take corrective action described in Section 8.1. - Intelligent function module setting switch 5 is set to "other than 0". Using GX Developer parameter setting, set intelligent function module setting switch 5 to "0".
What to do if the input signal is not turned OFF on my Mitsubishi MELSEC Q?
If the input signal on your Mitsubishi Controller isn't turning OFF, it could be due to leakage current from the input switch. To resolve this, connect an appropriate resistor to lower the voltage across the input module terminals below the OFF voltage value. For AC input, it's recommended to use a CR constant with 0.1 to 47 F + 47 to 120 (1/2W). Another cause might be a limit switch with a neon lamp, in which case you can apply the same resistor solution or create an independent display circuit. Finally, leakage current from the wiring cable's line capacity could be the issue. The same resistor fix applies here, but note that leakage current isn't generated when the power supply is located on the input equipment side.
