9-2-3 Collecting Operation Data
This function is used to collect the operation data of the outdoor and indoor units via M-NET, and record the data in the flash
memory on the control board. When the memory is full, it is overwritten from the first segment.
The settings for checking the status of operation data collection, for starting/ending data collection, and for continuing/stop-
ping error-data collection are made, using the switches on the control board. The items to be set are shown in the table below.
The data collection setting is enabled by default, and the setting for error data collection during an error is disabled by default.
*When setting the switch SW4 on the control board, make sure the outdoor unit is energized.
Also use Section [5-1 Dipswitch Functions and Factory Settings] as a reference.
The procedure for making the operation data settings is shown below.
1. Operation procedure
(1) Status Confirmation
1) Confirm the current status of operation data collection by setting the switches on the control board following the table shown
above.
Switch setting: SW6-10: OFF
SW4: 28
Check the status on the maintenance LED display (LED301).
* For details, refer to Section [9-4-1 Maintenance LED Display Content List]

Œ
When “Err” is displayed, go to step (3) and the later steps.
Œ
When “F-Er” is displayed, it indicates an error in the flash memory on the control board.
Refer to Section [9-4-2 Troubleshooting]
(2) Setting Start and End of data collection
1) Set the switches on the control board by following the table shown above.
Switch setting: SW6-10: ON
SW4: 817
2) Press SWP3 (ENTER).With each switch operation, the setting can be alternately switched ON and OFF.
3) After conducting step (1), check that the operating condition is stable.
Data collection start: OFF (Enabled)
Data collection end: ON (Disabled)
Setting procedure is now complete.
(3) Settings for error-data collection during an error
Stops or continues error-data collection when an error occurs.
1) Referring to the table above, set the control switches.
Switch setting: SW6-10: ON
SW4: 818
Stop collecting error-data when an error occurs: OFF
Continue collecting error-data when an error occurs: ON
2) To set the switches, press SWP3 (ENTER). Each pressing of SWP3 (ENTER) toggles between ON and OFF. Error data in
the 6000's and the 7000's will be collected, regardless of the SW4 (818) settings.
(4) Restarting data collection
1) If “Err” is shown, it indicates that data collection is being suspended for some reason, even though data collection is enabled.
To restart, it is necessary to set the switches on the control board. Referring to (2)-1) and (2)-2), set the switches on the control
board from OFF (original setting) to ON, and then to OFF again, and make sure the switches settings are indicated as being
ON, following the instructions in (1)-1).
