The corrections that must be made if the AG-150A/G-50A fails or is replaced when using the power
apportioning billing function are explained in this chapter.
Clearing the charge comparison data when AG-150A/G-50A is replaced
Clear the charge comparison data in the replaced AG-150A/G-50A following section 9.6 "Maintenance of
charge data during AG-150A/G-50A, PLC fault or replacement".
[Procedure]
→ Refer to section 9.6.
Target: Only AG-150A/G-50A that has failed or been replaced.
Example of "Charging data maintenance" when AG-150A/G-50A fails (for power apportionment
billing (manual electric amount input)
An example of the corrections is given below.
[Procedure]
1) Select the [Charging Data Maintenance] button
From the initial window, click the [Charging
Data Maintenance] button in the Maintenance
group.
2) Select the AG-150A/G-50A to be corrected.
Select the replaced AG-150A/G-50A from
"Select from AG-150A/G-50A".
3) Select the indoor unit icon.
The "Unit Apportioning Data Maintenance"
screen opens when the icon for the indoor unit
to be corrected is clicked.
4) Correct the apportioning parameters.
Correct the apportioning parameter for the
fault period to "0". The value will change to
blue when corrected.
* The correction target period is from the date of fault
occurrence to the day before recovery.
5) Correct the indoor units connected to the replaced AG-150A/G-50A.
Correct the contents of the apportioning parameters (only fault period) of the indoor units managed
by the replaced AG-150A/G-50A to the contents shown in step 4).
6) Select the methods for correcting the fault period from the following methods.
The apportioning parameters for the fault period are processed with a special method, so select the
correction method that matches the system. As an example, the following plans are given.
Plan (1): Correcting using the average value for the week before the fault
The average value of the week before the fault is used as the apportioning parameter for one
day. The apportioning parameters multiplied by the number of days in the fault period are
calculated and input as the apportioning parameters for the day before the fault was recovered.
Plan (2): Correction method using only correct period
The apportioning parameters for all indoor units within the fault period are not used. Instead
only the correct period is used. Thus, the apportioning parameters for all indoor units during
the fault period are set to "0".
7) Correct the apportioning parameters according to step 6).
Correct the apportioning parameters for the corresponding indoor unit and date using the fault
period correction method decided above.
8) Select Recalculate.
If the account has already been settled, select Recalculate and recalculate the account for the
corresponding month.
Appendix 3: Correcting the Power Apportioning Bill When AG-150A/G-50A Fails or Is Replaced
Note:
• The power apportioning charges for the fault period cannot be calculated if the AG-150A/G-50A is
replaced, so special corrective measures must be taken when a fault occurs.
