9-2 Operation Data Collection and Storage Functions
Operation data of the units collected on the outdoor unit can be recorded in the flash memory of the control board. These data
canalso be exported to and recorded in a USB memory stick.
See Section [9-2-2 Storing Data on a USB Memory Stick] for information on storing data on a USB memory stick.
See Section [9-2-3 Collecting Operation Data] for information on the collection of operation data.
9-2-1 Preparation
A USB memory stick and a portable battery charger are required to store data on a USB memory stick (not supplied).
Prepare a USB memory stick and a portable battery charger as described in Section [9-1-3 Necessary Materials].
9-2-2 Storing Data on a USB Memory Stick
Store operation data recorded in the flash memory on the control board in a USB memory stick.
The content of the stored file can be confirmed using the maintenance tool.
Operation data should be stored in a dedicated mode (Store Mode).
1. Procedure
(1) Preparation of a USB memory stick
1) Since the size of the saved file containing operation data is 50 MB, prepare a USB memory stick with 50 MB or more available
memory. A USB memory stick which has other data in it may also be used. However, it is recommended to clear the remaining
data in advance to prevent any malfunctions.The saved file is named "MNTXXX.MT." XXX represents a serial number from
000 to 100. Since files named "MNT101.MT" or more cannot be created, unnecessary folders and files should be deleted.
(2) Storing data on a USB memory stick
Data can be stored to a USB memory stick either with the main power to the outdoor unit turned on (Method 2) or off (Method
1). For safety reasons, it is recommended to store the data on a USB memory stick with the main power to the outdoor unit
turned off (Method 1). If turning off the power is not feasible, take appropriate measures to ensure safety.
[Method 1 (recommended)] Storing data on a USB memory stick with the main power to the outdoor unit
turned off
<Starting up the unit in the data storage mode>
Œ
Turn off the main power to the outdoor unit.
Œ
Connect a USB memory stick to the USB port (CNUSB) on the control board.
Œ
With SWP3 (ENTER) being held down, connect the portable battery charger to the XA connector (CN601) for the PCB, and
supply power to the control board. Wait for five seconds until the USB memory stick is recognized.
Œ
[USB] will appear on the monitoring LED301. If "USB" does not appear, refer to Section 1.(1) in [9-4-2 Troubleshooting].
Œ
When [USB] has appeared on the LED, lift the finger off SWP3 (ENTER).
The unit is now in the data storage mode.
<Storing data>
Œ
Press SWP3 (ENTER). If the data storage process has properly started, the progress (0-99) will be shown on the monitoring
LED 301.
Œ
[End] on the LED indicates successful completion of the data storage process.
*It takes approximately five minutes for the data storage process to be completed.
<Ending the data storage mode>
Œ
When done storing data, disconnect the portable battery charger from the control board.
Œ
Then disconnect the USB memory stick from the control board.
Œ
Turn the main power to the outdoor unit back on.
Œ
If the data collection process needs to be started, check the operation data collection status by following the procedures ex-
plained in [9-2-3 Collecting Operation Data]and making the necessary settings.
