General errors and warnings

TypeKeyDescription
warningalert_stateThe battery reports that it is currently in an alert state. The alert state is defined by Tennet as an event of a larger frequency deviation, an alert state is activated when the frequency deviation is higher than 50 mHz for 15 minutes, higher than 100 mHz for 5 minutes, or instantaneously higher than 200 mHz. Consult the FCR handbook for more information about the alert state. This warning is not supported by the Alfen battery.
warningrecovery_stateThe asset reports that it is currently in a recovery state. Recovery state is defined by Tennet as an event after which the battery must have the awarded/contracted amount of FCR fully available again which can take up to 2 hours. During this time, FCR functionality shall be disabled. This warning is only supported by the ATEPS battery with FCR module. battery.
warningreserve_modeThe asset reports that it is currently in reserve mode. The transition to reserve mode is initiated once the state of charge thresholds are reached or exceeded, while the system is in alert or emergency state. For more information about reserve mode consult Tennet’s explanatory note.
