Fault 51 Analog processing
Error: 51.1 (3301hex | 13057dec) Description: Current at analog current input too small | ||
|---|---|---|
| Response: Analog input – 4 mA limit undershot | |
Cause | Measure | |
Input current at analog input below 4 mA. | – Check the wiring. – Check the parameterization of the analog input. | |
Error: 51.2 (3302hex | 13058dec) Description: Voltage/current changeover faulty | ||
|---|---|---|
| Response: Output stage inhibit | |
Cause | Measure | |
The hardware configuration for switching between voltage input and current input on the basic unit does not match the parameterization of the analog input. | – Check the position of the switch for the current/voltage configuration or – Check the parameterization of the analog input. | |
