After those retries, try a hard reset of the Dock at the breaker. If that does not work, create a work order to replace the charger.
SLOW_CHARGE_RECOVERY_ACTIVE. The Aircraft retries charging over a 24-hour recovery window and the Dock will try to restart its charger service. If the recovery window expires without a successful charge-start attempt, MAX_RETRY_ATTEMPTS_FAILED sets.The default action for an active slow-recovery alarm is to leave the Aircraft docked and allow recovery to continue. If the asset needs to be restored before the 24-hour recovery window expires, use SLOW_CHARGE_RECOVERY_ACTIVE to troubleshoot the underlying Dock or Aircraft charging issue.
