Precautions
For dealing with display on the maintenance LED and other problems, refer to Section [9-4 Maintenance LED Display and
Troubleshooting].
1. Storage of data in a USB memory stick
Take extra care regarding electric shock during the work on the control board, such as the insertion of the USB memory stick.
Before starting in Normal Mode, remove the USB memory stick from the control board.
Storing data in the USB memory stick may take a long time resulting in OS and communication errors. These errors affect
neither storing process nor unit operation. If an error occurs, refer to [9-4-2 Troubleshooting].
After normal startup, set the operation status of the air-conditioning units to the original status.
USB memory sticks may become unusable due to unexpected damage or memory shortage. It is recommended to take extra
USB memory sticks to the site.
If only the OS is operated due to problems with the OC, collect data also from the OS by following the same operation proce-
dure as for OC. Refer to Section [9-2-2 Storing Data on a USB Memory Stick].
2. Collection of operation data
The collection of operation data does not start immediately after power-on, but does after ten minutes.
When the operation data are being collected from AE-200 or the Maintenance Tool, the function to collect outdoor unit (OC)
data with a USB memory stick will not be available for use.
