Protection characteristics Fault and alarm reset button Fault/Alarm LED In normal state, this LED is off. In case of fault release, the red LED will flash quickly; in case of alarm, the red LED will be on constantly Normal LED As long as the controller is on and operates normally, the green LED always flashes Communication indicator The communication state indication is as follows: Profibus: OFF if no communication; ON if communication exists Modbus: OFF if no communication; flash if communication exists Device Net: Flash if no communication; ON if communication exists Curve LEDs Red LEDs exist behind the curve. In case of fault release, the corresponding LED will flash indicating the fault type; During the parameter setting process, the LED is always on and indicates the current item.
