LED displays
LED | Color | Description | |
---|---|---|---|
Run | green | On | Normal operation |
Off | Watchdog-timer overflow has occurred. If no process data is transmitted to the bus coupler for 100 ms, the green LEDs go out | ||
Error | red | On | The respective channel is affected by a short circuit or broken wire. The resistance is in the invalid range of the characteristic curve. |
Off | The resistance is in the valid range of the characteristic curve. |
