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.
9.3 Operation Amount Data Monitoring
When the operation amount data is monitored, it is possible to read the operation amount data for the
indoor unit provided for each G-50A.
<Description of function>
The system monitors the operation amount for the indoor unit from all the 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, subsidiary 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 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.
<Supplement> The G-50A retains the data for the last 62 day s.
<Caution>
Even if the operation amount data is monitored, it may not be executable in some cases due to the
following reasons:
• When the data has not accumulated due to a power shutdown for over 24 hours of the G-50A
• When the data has not accumulated due to setting the time/date of the G-50A and PC forward
by over 24 hours
• When the G-50A is replaced due to G-50A failure
When the operation amount data is monitored by the system (2000 units) for one month, it takes
approximately one hour.

• 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
