Mitsubishi Electronics TG-2000A operation manual Apportioning method when computer crashes

Note:

•“Recovery day” is the day the system was recovered from a HDD failure and is the day normal operation was restarted.

•When charge is not apportioned normally for the day before the remedial apportioning start day, change the remedial apportioning start day to the day after the day normally charged before the backup day.

11)Watt hour meter integrated value setting

The value at 24:00 hours of the day before backup is displayed at the watt hour meter integrated value of each watt hour meter. The watt hour meter integrated value does not have to be corrected.

Note:

•When a value is not displayed in the watt hour meter integrated value field, there is no data in the database. Since a setting error is possible, check the remedial apportioning start day.

•Normal charge apportioning is necessary for the day before backup.

When setting of the remedial apportioning screen is complete, perform Section 9.5.2 “(3) Calculate remedial apportioning” .

9.5.5 Apportioning method when computer crashes

The following describes the apportioning method when the computer crashes and the charging data is abnormal and apportioning (un-apportioned) cannot be performed.

Note:

•Whether or not un-apportioning of charging data was generated by a computer crash can be checked at the “Charging data maintenance” screen.

•When the charging data is not apportioned, this remedial apportioning is unnecessary.

This is described with the time serial example below.

Count (1 month)

1)Computer down time chec k

Check the time the computer was shut down at the “Charging data maintenance” screen. When nothing exists in the charging data, the numbers are displayed in gray.

2)Operation amount backup monitoring

Monitor backup of the operation amount from the day the computer crashed to the day it was recovered. Set the start day as the computer crash day and the end day as the day before recovery day.

Note:

•Operation amount backup monitoring can be performed for the recovery day also.

3)Start remedial apportioning.

Start remedial apportioning by clicking the ]Remedial apportioning] button in the initial window.

Note:

•Begin remedial apportioning from the day after the settlement-of-accounts day. However, except when it is different from the normal settlement -of-accounts term. Remedial apportioning can begin two days after the recovery day. (Only when the day after the recovery day was normally charged.)

4)Settlement -of-accounts term setting

Set the settlement-of-accounts term (start day and end day) at the remedial apportioning setting screen. The initial value is the settlement-of-accounts term of the previous month.

5)Total air-conditioning charge setting

Set the settlement -of-accounts term total air-conditioning charge.
