9.2.5 Verify Test Operation of Watt Hour Meter
Follow these steps to display the watt hour meter monitor.
Watt hour Meter Monitor Function
[Procedure]
1) Select the watt hour meter.
From the Charge Data Maintenance screen, select the
meter to monitor using the “
”
button.
2) Click [Present Value Monitor] button.
Click the [Present Value Monitor] button. The Watt
Hour Meter Current Integrated Value screen appears
for the selected meter.
3) Click [OK] button.
When finished viewing these values, click the [OK]
button.
When the [Monitor] button is clicked, the watt hour
meter integrated value is monitored again.
Changing the watt hour meter present value
1) Select the [Present Value Change] button, and set the
new value.
From the Charge Data Maintenance screen, select the
meter to monitor using the “
” button. Then, click the
[Present Value Change] button.
The Present Value Change screen, on which the value
can be changed, opens.
* Turn OFF the power breaker for the target watt hour meter's
measurement wire before starting.
* The data for charge calculation cannot be changed.
9.3 Operation Amount Data Monitoring
The indoor unit operation amount data saved in each AG-150A/G-50A, or the watt hour meter
(including all meters) cumulative value data saved in each PLC can be read out using the operation
amount and electric amount data monitor.
<Description of function>
The system monitors the operation amount for the indoor unit from all the AG-150A/G-50A units to
calculate the proportionally divided power charge at 4:05 and after every day. (Operation amount of
indoor unit: capacity save ratio, FAN operation time, thermo-ON time, auxiliary heater operation time)
The proportional division is not calculated properly when the system is unable to monitor because the
power of the PC that the integrated centralized control software (TG-2000A) operates on is turned off,
the PC is defective, or the LAN circuit or hub with the AG-150A/G-50A is defective. (The calculation
result is correct, however, as the forwarded calculation is executed after the repair on the next day or
at a later time, but the calculation result is displayed in red as an error (red).)
Because of the reasons shown above, the Operation amount data monitor function is used to monitor the
operation amount data as a guideline (cannot be monitored) with the date designated using the charge
data maintenance described in 9.2 or the charging remedy described in 9.5 when the maintenance of the
proportional division parameter value or the apportioned electric power is performed.

Note:
• This screen can be used to verify the connection to
the watt hour meters.
• The test operation integrated value may have a time
lag of 10 seconds to 2 minutes.
• This function cannot be used for Without WHM
connection proportionally divided electric charge.
• WHM test operation can be performed at the
Management screen also. Refer to section 8.5 of the
Management manual.
