a) Items to be obser

ved in selecting PC

b) Items to be observed in use

Please select a PC of desktop type.

• Since a program is required to always be operated under powered state depending on the functions to be used, it is recommended not to employ a note type PC but employ a desktop type PC. It is because that the note type PC tends to be filled with heat more easily than the desk top type PC.

• Some note type models can not be operated for a long time.

Please prepare a PC/operating environment with specification allowing TG-2000A to exhibit its function fully.

• Use the OS with the specified operating environment. With other OS than specified, TG-2000A may not possibly be operated.

• Use a business model PC. In the case of the personal use model if employed, TG-2000A may not be installed or trouble may be induced in its operation due to confliction with other application.

Recommend to install a UPS system on your PC.

• In order to prevent your data from being damaged or missed by the instantaneous stopping or failure of the power supply, it is recommended to install a UPS (Uninterrupted Power Source system) on your PC. Especially when using the power apportioned charging function, make sure to install the UPS without fail.

Do not place your PC unit at such places as below.

• Otherwise erroneous operation or malfunction will be caused.

A dusty place; a place where shock or vibration is applied; a place with unstable foundation; a place near heating equipment; a place near strong magnetic field like speaker; a place exposed to direct sunlight for a long time; a place likely causing falling down; a highly humid place; a place with abrupt temperature change; a place where heat is stagnated

c) F

or others

Regarding PC and its peripheral equipment;

• For the trouble of your PC or its peripheral equipment, ask the maker. Please note that our company is not responsible for such trouble.

Please do not clog the ventilation opening of your PC.

• If clogged, the internal temperature will r ise, and a fire or machine trouble may be caused. Use your PC under well ventilated condition.

Do not touch the ventilation opening of your PC.

• As the temperature of exhaust air through the ventilation opening is higher than the room temperature, a burn may be caused if touched.

When a note type PC is used, do not close its lid.

• Otherwise, the internal temperature rises due to the stagnated heat which may cause a fire, burn or machine trouble. Use the PC with the lid opened under well ventilated condition.

For the PC and its peripheral equipment, be sure to read their installation manuals or instruction manuals.

• Erroneous handling may cause a fire or trouble of the PC and its peripheral equipment.

Do not leave your PC unit or AC adapter being covered with clothes or bedclothes near or on a heating instrument.

• If placed, the internal temperature will rise possibly causing a fire, burn or machine trouble.

When smoke, abnormal odor or sound is generated from the PC unit, or the unit is heated to such extent that you can not touch it directly with your hand, pull out the plug of the power cord from the plug socket immediately.

• Continuing to use under such state may cause a fire, burn or electric shock. Consult your dealer or PC maker in such case.

Please observe the caution on handling of the hard disk, floppy disk and CD media.

• Do not give shock or vibration to the hard disk, floppy disk or CD under operation.

• Do not turn the power source off or restar t when the hard disk, floppy disk or CD is operating.

• Please do not move your PC being powered.

(3) Function list

By utilizing the software (TG-2000A) and collecting the data of each G-50A, the operation control can be performed for up to 2000 sets in a unit of each floor or block on the PC screen.Please refer to section 2,3 for function licence. Additionally by using PLC (Programmable Logic Controller), general equipment can be controlled in addition to the electric power apportioning function and energy saving control.

Switching start (Hi/Lo)/stop for whole building, or in a unit of block, floor or group when connecting with interlocked equipment (Lossnay). (However, ventilation mode can not be selected for interlocked equipment.) For whole building, or in a unit of block, floor or group, items for which local control is prohibited can be selected. (The items include start/stop, operation mode, set temperature, filter sign reset.) License registration allows you to use the annual/weekly schedule function. Two seasonal setting (for summer and winter) can be used. Through the license registration of G-50A unit, the power apportioning rate data per indoor unit can be output in CSV format. Further by inputting the WHM amount manually, the power consumed by each tenant can be calculated easily. By registering license to G-50A, the air conditioning charge can be calculated through the apportioning of power consumption based on the air conditioner operating record per tenant by using PLC (Electric power counting software: PAC-YG11CDA) and WHM with pulse oscillation device. Through the registration of license number to G-50A unit, the power consumption of air conditioner by each tenant can be calculated by using PS-485 watt-hour meter (only for the designated models). The abnormal history record can be stored up to 3,000 and operation history record can be stored up to 10,000 respectively. The history record may be output as a daily and monthly record in CSV format. The integrated operation time of each indoor unit group*1 can be observed. It can be output as a file in CSV format. (This function is only effective when registering the charging function for license.) The automatic display of the filter sign may be suspended. (for a whole system collectively) In this case, the state of the filter sign can be checked by manual operation. With the schedule by a group unit, a temperature of 12 ~ 16˚C can be set under heating mode. However, only the M-NET indoor units are objected, while K-control and A-control indoor units are not objected. This function is effective only for ME remote controller system. It is possible to control the set temperature range from the hand remote controller or the browser screen of general users. The range limits include the lower limit value at cooling and the upper limit value at heating. By the way, this function is available only in the ME remote control system. By installing the general purpose control software to PLC, it is possible to schedule the operation and stop of other manufacturers’ air conditioners and facilities, and monitor them and monitor their error. By registering the license number to G-50A, energy saving control is available. By setting the control contents per block from TG-2000A, energy saving rotation operation is carried out in unit of group. By registering the license number to G-50A, energy saving peak cut operation is available according to the electricity use amount. This control requires PLC (electric power amount count software) separately, and by connecting an electric power meter, energy saving operation can be made according to the electricity use amount.

* The above functions are subject to change for improvement without notice.

Operation time of minimum address unit is displayed in group.

Notice

●The operation prohibition settings to K control type are only operation/stop, operation mode, and temperature setting. Whether prohibition or permission on these 3 items cannot be set individually.

●

In the group controlling LOSSNAY, only operation/stop, and filter sign reset operation can be set for prohibition.

Figure 4-1 shows the wiring example of M-NET bus. When the centralized control system M-NET bus and indoor-outdoor transmission M-NET bus per one system are shown in relation with the wiring length limitation, the total wiring length in the following example can be expressed by the following equation. This represents the distance limitation to perform proper communication with other equipment on M-NET bus. If this distance is exceeded, M-NET signal can not reach the end equipment thus making the communication and control impossible.

[Caution for wiring connection work]

● The wiring connection work of the equipment delivered (MELANS equipment, air conditioning equipment, etc.) including power and earth lines.

● Install the transmission line and signal line apart from the power line and earth line. If not, the noise from the power/earth lines will mix into the transmission line or signal line causing to generate erroneous operation.

● In case of shielded line, provide one-point grounding at each transmission line. (Relay shielded line at the terminal block of each equipment.)

CAUTION

5. Step 2:

Selecting System Management Parts

5.1 M-NET system structure

There are cases in which other System Controllers (SC) besides model G-50A can be run on the G-50A system structure. In order to do so, the following outlines a number of rules to be observed for system management.

Figure 5-1 System controller concept

Disable the prohibit remote controller setting

G-50A

System

remote controller

Upper SC

Slave SC

SC enabling the prohibit remote controller setting

Power supply unit

(PAC-SC50KUA)

5.1.1 Concept of the system controller

The G-50A is always the host system of a self-controlling system structure. In addition, for a SC enabling the setting to permit prohibition of the local remote controller operation, please set up the system in such a way the setting is done with 1 SC unit for the remote controller in question.

(1) Significant system controller and insignificant system controller

When an air condition system is supposed, the system controller (SC) to control the entire operation system connection information is positioned as the significant SC. While, the insignificant SC means the SC to control sir conditioners by receiving the operation system connection information from the significant SC. Therefore, the initial settings including group setting and so forth may be made basically only on the significant SC, and there is no need to carry out the group setting on the insignificant SC. Priority of the significant SC is determined according to the functions of the SC (the number of units to control, the number of groups to control, etc.). G-50A is the most multifunctional type in the system, accordingly it always becomes the significant SC.

(Significant SC priority) G-50A > PAC-SF44SRA > PAC-YT34STA > PAC-YT40ANRA > PAC-SC30GRA > PAC-YV02LMAP

(2) SC enabling the prohibition remote controller setting

A SC able to set the prohibition of operation using a remote control, is called a “SC enabling setting of the remote controller operation prohibition.” Please make sure, the number of SC units enabling the setting of the remote controller operation prohibition, is one always one unit for every remote controller. Normally, in the G-50A system, the G-50A is the SC enabling the setting of the remote controller operation prohibition. However, in the case you want to disable operation of the remote controller using another SC (lower SC), please select “Disable the setting from this unit to prohibit remote control” during initial set-up. For details, please refer to the operation manuals of each SC.

5.1.2 Regarding power supply within the system

(1) Regarding power supply parts

Within the G-50A system, the parts serving to supply electricity are fixed for each transmission line. Please take care there is no electricity supply overload to any one transmission line.

Centralized control transmission line : supplied by transmission line supply unit Indoor/outdoor transmission line : supplied by outdoor unit K-control centralized transmission line : supplied by K-transmission converter (KA) Extended transmission line : supplied by relay port

Only for the Lossnay system, please use the power supply unit (PAC-SC50KUA, PAC-SF46EPA).

Figure 5-3 Electricity supply using a Lossnay system

(2) Definition of the supply connector in the outdoor unit

In the outdoor unit, the power supply to the centralized control transmission line is fixed at the location where the supply connector is packaged. When using the G-50A, it is recommended to connect the G-50A to the centralized control transmission line. Therefore, package the supply switching connector at the CN-41 side and please don’t supply power to the centralized control transmission line.

5.1.3 Selecting the power supply unit

G-50A is driven by DC12V from the Power supply unit : PAC-SC50KUA. To communicate with the air conditioner, it is necessary to connect to the M-NET transmission line in addition. First determine whether G-50A is connected to the centralized control transmission line or to the indoor/outdoor transmission line.

Figure 5-4 Caution for power supply

Figure 5-5 Connection of centralized control transmission line

To connect with the indoor/outdoor transmission line, connect the DC12V output (TB3) of PAC-SC50KUA to G-50A only. For the M-NET terminal (TB2) of G-50A, connect the indoor/outdoor transmission line. Never connect M-NET line to the M-NET terminal (TB2) of PAC-SC50KUA. Allow the wiring length of DC12V up to 10m maximum. Please observe the following restrictions also.

- Connect the power supply connector to CN40 on the one

- outdoor unit only.

- To use the power consumption apportioning function,

- do not install on the indoor/outdoor transmission line.

To connect with the centralized control transmission line, leave the power supply connector of the outdoor unit being connected to CN41.

● As G-50A works to back up each data, recommend to install it on the centralized control transmission line.

● If G-50A is installed on the indoor/outdoor transmission line, communication can not be performed even with air conditioners in other systems at power failure if occurred on the connected outdoor unit. To use the power consumption apportioning function, therefore, be sure to install it on the centralized control transmission line.

CAUTION

(1) Connecting to the centralized control transmission line

The Power supply unit : PAC-SC50KUA is required.

(2) Connecting to the indoor/outdoor transmission line

To connect G-50A to the indoor/outdoor transmission line, use the DC12V output terminal (TB3) of PACSC50KUA only to supply DC12V from this terminal to G-50A. For the M-NET terminal of G-50A, connect the indoor/outdoor transmission M-NET line.

*The M-NET terminal (TB2) of PAC-SC50KUA is not used. Never connect the M-NET line.

When connecting G-50A to the indoor/outdoor transmission line, the quantity of indoor units connectable to the refrigerant system decreases. The quantity of indoor units connectable is decreased by 2 sets per 1 set of the system controller (including G-50A) connected to the indoor/outdoor transmission line. [Example : In case of BIG Y Series (PUHY-P400YMF)] The quantity of indoor units connectable to an outdoor unit counts for 16 sets. When connecting the system controller (like G-50A) to the indoor/outdoor transmission line, the connectable quantity will be 14 sets. (16 sets –2 sets = 14 sets)

Remarks

Together with G-50A, other system controllers can be connected to the centralized control transmission line. The G-50A of one set and other system controllers up to 4 sets can be connected to the centralized control transmission line. When connecting the Lossnay remote controller to the centralized control transmission line, that up to 16 sets can be connected when one set of G-50A is connected without other SCs. The table below converts the receiving capacity of each system controller into that of Lossnay for your reference.

5.1.4 When managing a K-control model

When managing a K-control type device, a separate K- transmission converter, model PAC-SC25KAA, is required.

(1) System controllers able to control a K-control type device

A K- transmission converter unit only accepts communication with a upper controller with bearing address [000]. Consequently, since the G-50A is fixed (address [000]) as the upper controller, even if multiple system controllers are included in a single system, control of K-control type de vices is only conducted using the G-50A.

5.1.5 Synchronized settings

The Lossnay with built-in heater and humidifier and which has been set for synchronization starts and stops operation synchronized with an indoor unit that has been set for synchronization. Furthermore, it is also possible to operate the Lossnay or the OA Processing unit independently using the ME remote controller that controls the indoor unit in question. Synchronized operation of two or more OA Processing unit in addition to a Lossnay unit using one indoor unit is impossible.

(2) Concerning the address of the K- transmission converter (PAC-SC25KAA)

The address of the K- transmission converter is [200 + the smallest address of the K- models]. The address of the K- transmission converter expresses the borderline of the M-NET type device and the K-control models. As a case example, in the case the number of G-50A units is 38 units and the address of the K transmission converter is [220], the addresses from [20] on and after are all interpreted as K-control type devices and are started up according to K-control. In other words, care has to be taken the addresses of K-control models are set after those of the addresses of the M-NET type devices, while fitting addresses should be set for the K -transmission converter.

●● OA Processing unit can be controlled as an indoor unit by setting the DIP

switches. In the case of OA Processing unit is to be controlled as an indoor unit, please set DIP switch 3-1 of the OA Processing unit to ON.

●● Synchronized operation of two or more Lossnay units with built-in heater and

humidifier in addition to a Lossnay unit using one indoor unit is impossible. With one OA Processing unit, synchronized registration of maximally 16 indoor units can be performed.

CAUTION

Optional: PAC-YG10HAA

5.2 External input/output
