Cause

If the old charger is not deleted after the replacement, it will be displayed as offline or faulty. In this case, you need to unbind the old charger from the plant.

Procedure

1. On the home screen of the app, select the target plant.
2. On the Device screen, choose : > Delete Device in the upper right corner of the target device card.
3. Tap Unbind Device or Delete Device as required.
   • After a device is unbound, the running data of the device and its downstream devices is stored in the database. The default data retention period is six months. To change the retention period, contact the system administrator.
     • If a device is rebound to a plant within the data retention period, the device inherits the retained data.
     • If a device is not bound to a plant within the data retention period, the data will be automatically deleted.
   • After a device is permanently deleted, the running data of the device and its downstream devices is deleted immediately. When the device is rebound to the plant, the running data of the device is not restored.
