1 action
Some faults are intermittent. Restart the charger service to see if it resolves the issue. For steps, see Restart Dock Charger Service.
2 question
Did the alarm clear?
3 action
If the Aircraft can be charged normally and no new alarms show up, the Dock may be put back into service.
4 action
Flip the breaker to turn the Dock OFF. For steps, see Power Cycle Reset Tripped Dock Breaker.
5 action
Wait for a minimum of 30 seconds.
6 action
Turn the power back on.
7 question <=2026.15
Is the issue resolved?
8 question >=2026.15.1
Is the issue resolved?
9 action
The Aircraft and Dock may return to service.
10 action <=2026.15
If restarting the charger service is unsuccessful, wait 5 minutes and restart the charger service again. If the second restart is still unsuccessful, wait 30 minutes and restart the charger service again. If the third restart is still unsuccessful, wait 3 hours and restart the charger service again.
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.

11 question >=2026.15.1
SLOW_CHARGE_RECOVERY_ACTIVE means the Aircraft failed its first 5 charge-start attempts and is periodically retrying over a 24-hour slow recovery window. The default action is to leave the Aircraft docked and allow slow charge recovery to continue. Do not power cycle the Aircraft just to clear the retry counter while recovery is active. Do you want to wait for recovery or troubleshoot now to restore the asset? 12 action >=2026.15.1
Leave the Aircraft docked and allow slow charge recovery to continue for up to 24 hours. If charging starts and the charging alarms clear, return the Aircraft to service. If
MAX_RETRY_ATTEMPTS_FAILED sets, follow MAX_RETRY_ATTEMPTS_FAILED. 13 action >=2026.15.1
If the asset needs to be restored before the 24-hour slow recovery window expires, use SLOW_CHARGE_RECOVERY_ACTIVE to troubleshoot the underlying Dock or Aircraft charging issue.
