8.4.1 Role of each item
(1)
Watt-hour meter with pulse oscillator (not required at using the electric power manual input method)
The watt-hour meter with pulse oscillator outputs pulses corresponding to the power consumption of air conditioners. The
pulse has unit (weight) such as 1kWh or 0.1kWh per 1 pulse for example. (TG-2000A recommends 1kWh or less per pulse.)
This watt-hour meter is essential when using the apportioning method or direct reading method.
RS-485 electric meter is needed for electric power count by PC direct connect (RS-485WHM). (1kWh or less per
pulse is recommended.)
(2) PLC (not required at using the electric power manual input method and electric power
count by PC direct connect)
The PLC (Sequencer) integrates the pulse output from watt-hour meters by dividing into the charging
time frame being set by TG-2000A.
In the case when the apportioning or
direct reading method is used, “Pulse
counting software: PAC-YG11CDA” is
required by PLC.
(3) G-50A
The G-50A monitors the operation information of indoor units required by charging for each 1 minute,
and holds the information in a unit of indoor unit dividing in the charging time frame. Such process is
conducted by G-50A regardless of the charging methods.
The information required for charging are as follows (Includes electric power count by PC direct connect (RS-485WHM)).
1 Operation time of indoor unit fan
2 Operation time of indoor unit auxiliary heater
3 Capacity saving amount (Time)
4 ON time of thermostat
In the case of the direct reading
method, the information collection by
G-50A is not necessary. However, the
license registration is required as the
charging function is used as same as
the other methods.

Add +1 at 1kW/pulse.
