6) Include/Not include standard charge setting
When the settlement-of-accounts term is one month, [Include] or [Not include] standard charge can
be selected. Set whether or not the standard charge is to be included.
7) Remedial interval setting
Set the apportioning interval. The apportioning start day is the computer crash day and the
apportioning end day is the recovery day.
8) Watt hour meter integrated value setting
The value at 24:00 hours of the day before the computer crashed is displayed in the watt hour meter
integrated value of each watt hour meter. The watt hour meter integrated value does not have to be
corrected.
When setting of the remedial apportioning screen is complete, perform Section 9.5.2 “(3)
Calculate remedial apportioning”.
9.5.6 Remedy when watt hour meter fails (monitoring impossible)
The following describes the remedy when a watt hour meter fails and the charging data is abnormal and
is not apportioned.
1) Recovery from watt hour meter failure
Locate and remove the cause of the watt hour meter failure. The cause of the failure may be an open
transmission line, CT failure, or failure of the watt hour meter itself.
2) Wait until the day after the settlement-of-accounts day.
After recovery, continue normal operation until the day after the settle-of-accounts day.
3) Start remedial apportioning.
Start remedial apportioning by clicking the “Remedial apportioning” icon in the initial window. This is
described by the time series example below.
Note:
• When the settlement-of-
accounts term is one month and includes a standard charge, set the
total air-conditioning charge including that standard charge.
• When there is one power charge, the total air-
conditioning charge does not have to be set. This
item cannot be set.
Note:
•
When the charge for the day before the apportioning start day is not apportioned normally,
change the apportioning start day to
the day after the first day charged normally before the
computer crashed.
Note:
• When a value is not displayed in the watt hour meter integrated
value field, there is no data in
the database. Since there may be a setting error, check the remedial start day.
• The charge for the day before the computer crashed must be apportioned normally.
Note:
• Operate normally up to the day after the settlement-of-
accounts day because remedial
apportioning is performed for one month.
Note:
• Perform remedial proportioning from the day after the settle-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.)
