Troubleshooting of the Mitsubishi Tension Controller LE 30 CTA
The Mitsubishi Tension Controller LE 30 CTA has a self-diagnosis function that detects and displays various errors and alarms on the LCD display. The errors and alarms are classified into two types: E-type and A-type. E-type errors indicate serious problems that require immediate attention and may cause damage to the controller or the machine. A-type alarms indicate minor problems that do not affect the operation of the controller but may affect the quality of the product or the efficiency of the machine.
The following table shows some of the common errors and alarms that may occur and their possible causes and solutions:
Error/Alarm CodeDescriptionPossible CauseSolution
E01Power supply voltage errorThe power supply voltage is too high or too low.Check the power supply voltage and correct it if necessary.
E02Output short-circuit errorThe output terminal is short-circuited.Turn off the power supply and check the wiring of the output terminal. Remove any short-circuit and replace the controller if damaged.
E03Output overcurrent errorThe output current exceeds the rated value.Turn off the power supply and check the wiring and load of the output terminal. Reduce the load or replace the controller if damaged.
E04Output overheat errorThe output circuit is overheated.Turn off the power supply and check the ventilation of the controller. Improve the ventilation or replace the controller if damaged.
