Problem description |
Corrective action |
| After first start-up of the protective device there is a pending trip. | Two red LEDs are illuminated at the front of the HMI. They indicate a trip and an alarm. | With the factory default settings the protection relay is configured with an undervoltage protection. Adapt the settings of the undervoltage protection or remove this module from the device project settings (if you do not need it). If you have any problems with acknowledging the pending alarm, please refer to "Failure of a relay output". |
| The switchgears can not be operated by SCADA communication. | Set the switching authority of the device to "remote". | |
| Current and Voltage measurement. | The measured values of current and voltage have a big fluctuation. | Adjust the field parameters´ general settings to the connected grid frequency (50Hz or 60Hz). |
| Relay outputs do not react. | The contacts of the relay outputs do not open or close. This can be checked by simulating a fault and checking the relay output contacts with measurement equipment. | Check the following issues:
