System LED |
Device Status |
Potential Error Cause |
Corrective Action |
| Off (not illuminated). | Other LEDs are also off. | Either no supply voltage or the power supply is faulty. | Please check the supply voltage. If it is OK, send the device to be repaired. |
| Undefined (not flashing). | Other LEDs are showing a random pattern. | The CPU board is faulty. | Send the device to be repaired. |
| Constant red or flashing red. | The HMI shows an error number. | Fatal system error. | Get in contact with the manufacturer. The Service-Team will provide a tool for error analysis. |
| Flashing green, switch to constant green within 30 seconds. | No error. The device is in its start-up phase. When the System LED switches to constant green, the protection functions are active. | No action necessary. | |
| Flashing red/green. | The device is up and running. The protection functions are working. | The device is operating and all protection functions are working. But the internal self-supervision module has detected a previous problem in the system. The issue has been recorded within an integrated fault memory. | Please refer to chapter “Self-supervision Error Codes”. You can quit the System LED by selecting <Operation/Reset/ SSV.Ack System LED>. |
| Constant green. | The device´s HMI is not operable. There are no Softkeys shown on the panel. Instead the panel shows „Startup“ or just the device type (e.g. EDR-5000) without any Softkeys. | The device is starting up. The protection functions are already working, but the HMI is still starting up. If this is not finished after 5 minutes, the device is probably busy with handling Ethernet packets (Connector X100). | Check if the following action makes the device´s HMI operable: Unplug the Ethernet (Connector X100). Is the HMI now operable, there is an error on your Ethernet network (e.g. an Ethernet storm). Please check your network traffic. |
| The HMI is not operable. A normal page of the HMI is visible: Either there are Softkeys visible or the LED status page is being displayed. | The device is busy with handling Ethernet packets (Connector X100). The protection functions are working. | Unplug the Ethernet (Connector X100). Is the HMI now operable, there is an error on your Ethernet network (e.g. an Ethernet storm). Please check your network traffic. Should this action not change the device´s behavior, please read the next entry of this table. |
|
| The HMI is not operable. A normal page of the HMI is visible: Either there are Softkeys visible or the LED status page is being displayed. There is no Ethernet connector (Connector X100). | Some of the device´s system parts are not working. The protection functions are working. | Leave the device connected to the supply voltage. Get in contact with our service-team. You will be supplied with a tool for error analysis. |
