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

6.2 About password control

When performing centralized control using a Web browser or the TG-2000A software, it is possible to restrict operations to approved users by setting a password to perform operations or functions please refer to section 2,3 for function licence.

6.2.1 Password control when using a Web browser

(1) For general users

A general user is a user who enters through the [index.html] web page. This type of user can operate and monitor the operation status of air-conditioning units. The default password for general users is [guest].

(2) For administrators

An administrator is a user who enters through the [administrator.html] web page. This type of user can operate and monitor the operation status of air-conditioning units in addition to setting their schedules (optional), monitoring abnormality histories, setting the current timetable and changing passwords. The default password for administrators is [admin].

6.2.2 Password control when using the TG-2000A software

6.3 About LAN

6.3.1 LAN types

For the LAN cable, a 10BASE-T type is recommended. As for the category, from the point of view of availability and the development of mixed systems with optical cables, the use of category 5 is recommended.

(1) Main cable type

6.3.2 About the hub

For the hub, there are a variety of models including the 10BASE-T/100BASE-Tx automatic switching type (switching hub), the exclusive 10BASE-T hub and the exclusive 100BASE-Tx hub. When using the G-50A, please select a 10BASE-T type.

(1) What is a cascade connection?

The term cascade connection refers to a series of hierarchical connections where multiple hubs are interconnected using cables and where ports can be added.

(2) Cascade connection step restriction

As the number of cascade steps increases, the transmission delay increases, making it impossible to distinguish the signal (collision signal) to recognize other devices. To prevent this, restrictions for the number of connection steps apply as follows.

LAN cable standard 10BASE-5 10BASE-2 10BASE-T 100BASE-Tx

Maximum wire length 500m 185m 100m 100m

Communication speed 10Mbps 10Mbps 10Mbps 100Mbps

Cable specifications Standard coaxial cable Fine-core coaxial cable Twisted pair cable (T) Twisted pair cable (T)

(2) EIA/TIA568 (category)

For the twisted pair cable, there are classifications standards determined by EIA/TIA. For Ethernet, 5 and 3 are used. The categories are divided by communication speed used where a speed of 10 times that of category 3 can be used with category 5.

(3) Switching hub

The switching hub means the hub that controls traffics at exchanging packets (communication data) among plural networks, and send packets to a specified address. Different from ordinary hubs, it carries out one-to-one communications among respective ports, accordingly, even when one set of ports is communicating, other por ts can communicate freely. By this function, conflict of signals can be restricted, and network performance can be improved. Fig. 6-2 shows the differences between an ordinary hub and a switching hub. When communication is made from the personal computer at 192.168.1.2 to the personal computer at

192.168.1.3, in the case of an ordinary hub, communication is sent also to the personal computer at

192.168.1.1. While, in a switching hub, communication is sent to only the destination that you want to communicate.

6.3.3 LAN wire length

A 10BASE-T network connected to the G-50A may have a maximum wire length of 100m as detailed in chapter 4.1. Consequently, when the LAN wire length exceeds 100m, the use of hubs will extend the maximum length to 500m.

Notice

● Be sure to always use a hub.

● Restrictions apply to the number of cascade connections when using hubs. Please

observe these restrictions.

Notice

● By use of a switching hub, it is possible to add hubs exceeding the connection stage restrictions specified in the section 6.3.3, and to expand the distance.

Example: In the case where 2-stage cascade connection is made by 100 Base-TX

repeater hub or the like, by use of a switching hub, the hub can be connected to 2-stage cascade.

●

When to connect 2 switching hubs, there is logically no restriction in the number of cascade connection stages, cable length (between nodes) or so. However, if the load of network becomes extremely high, delay may result, causing network connection problems.

● As for the details of switching hub, refer to the operation manual attached to each switching hub.

7. Step 4:

Implementing annual/weekly schedules

With the G-50A main unit, weekly schedules can be implemented. However, when registering for a separate license (Annual/Weeky schedule), multifunctional weekly schedules and annual schedules can be performed. Please refer to section 2,3 for function licence.

(1) What is the weekly schedule?

This term refers to the operation schedule of each day of the week.

(2) What is the annual schedule?

Deviating from the weekly schedule, for special days (including commemoration days and holidays) a different schedule can be set for a maximum of 50 days up to 24 months (including this month) in advance. During the days set, the weekly schedule settings will not be implemented while the schedule set in the annual schedule will be implemented.

(3) What is the day schedule?

After setting the weekly and annual schedules, the day schedule can be used for sudden changes in the regular schedule. When the day schedule is set, the weekly and annual schedule settings will not be implemented. However, from the following day operations will be resumed according to the settings of the weekly and annual schedules.

7.1 Weekly schedule using the G-50A

The following explains the outlines the weekly schedule set using the G-50A. If the weekly schedule is set using the G-50A, setting is required to be performed using the G-50A for every G-50A unit.

1The timetable for start/stop can be set in increments of 10 minutes. 2For the daily operation schedule, up to 3 settings for each of the start and stop times for operation

can be set.

These settings can be set per group as P1, P2, and P3 as (1 type) of the operation prohibition schedule patterns at the local remote controller.

3In addition, it is possible to set the schedule for the same day by combining the start/stop operation

prohibition schedule patterns. ( , , )

4As the contents of the set schedule can be saved to memory, copying schedule patterns to other

groups is easy.

The schedule functions when performed with the TG-2000A are similar to the settings performed with the Web browser, except for the possibility to store the two patterns [Summer Master] and [Winter Master]. The [Summer Master] and [Winter Master] set with the integrated software are stored, to enable transmission to the G-50A main unit in accordance with the user’s needs. By transmitting these data to the G-50A, they become the [G-50A Master data] and will be executed by the schedule of the G-50A main unit.

8. Step 5: Charging Function of Energy Charge Measuring

This step is to set the charging function of measuring instruments to be performed by TG-2000A. This setting is required to use the charging function by measuring instruments. Since this function is optional, license registration to the G-50A unit is essential to use the charging function by measuring instruments.

8.1 Outline

Before explaining the charging function by measuring instruments, each term used here is introduced.

(1) What is the standard charge?

This indicates the contracted standard charge of each measuring instrument (electric power, gas, city water, calorie meter). The standard charge is set in the unit of each tenant (charge block) for air conditioning energy charging. While for the direct reading of other measuring instruments, it is set in the unit of measuring instrument. In the case of electric power used for air conditioning, the standard charge represents the contracted charge of air conditioning system among the contracted electric power charge of whole building per tenant. The monthly charge is fixed.

[Example of calculation method of standard charge]

The contract charge of air conditioning among the contract electric charge of a whole building is calculated.

Standard charge (Yen) = × Contract electric capacity × Capacity unit price

This standard charge is divided in proportion with the air conditioning electric capacity per tenant (charge block).

Air conditioner electric capacity of control target

Total electric system capacity of whole building

Standard charge of charge block

In the case of the apportioned system, the standard charge is set in a unit of the charge block.

Standard charge of

measuring equipment

In the case of direct reading type measuring equipment,

the standard charge is set in

a unit of the measuring

equipment.

The standard charge can not be set in the case of the electric power manual input system. It shall be added separately.

Figure 8-1 TG-2000A standard charge setting screen

[RE: Apportioning of air conditioning power consumption] Since the watt-hour meter value of power consumption is apportioned by judging the operation status of the indoor unit from detailed communication between the indoor and outdoor unit, this value can not be applied to the business certificate legally defined. The same limitation is applied to the case of direct reading of measuring instrument unit. In order to employ this system, therefore, it is recommended to conclude an agreement or contract between the building owner and tenants stipulating that [The air conditioning charge should be collected through apportioned calculation based on the operation status (including the temporary processing measure at trouble)]. (1) This system does not measure the power consumption of each indoor unit directly. (2) As the system estimates the power consumption of air conditioning, the valued obtained herewith may not be applied to the certificate

of business transaction. (3) Even if the operation time of air conditioners is same, the power consumption differs depending on the operating status. (4) As air conditioners are powered even when they are stopping, the power consumption will be charged. (5) One watt-hour meter should be connected to one air conditioner. If connected to plural air conditioners, an error will be caused due to

the apportioning of total power consumption. (6) At the failure of PC, G-50A or PLC, the average apportioned value in the past may be adapted for temporary transaction as a solution. (7) As the power consumption and gas consumption is taken in the form of a pulse, the performance and accuracy are depending on that

of the measuring instruments employed. Under this circumstance, we are not liable for the performance and accuracy presented. (8) As the resultant air conditioning charge is rounded to the nearest whole number at a figure not shown here, please note that an error

generates between the air conditioning charge of watt-hour meters and that of the block total.

CAUTION

(2) What is charge?

This represents the charge of electric power, gas or water consumed by each air conditioner or tenant (In the case of using electric power count by PC direct connect (Watt Hour Meter (RS-485)), only electric power can be counted). The charge of such consumption can be calculated by the following 2 methods, and the output can be presented in printer output or file output in CSV format.

● Calculation for clearing day On the clearing day registered to TG-2000A, the monthly charge is calculated automatically. The standard charge is also added. The clearing day may be selected in two ways, from the clearing day specified or the end of the month. In the case of the clearing day specified, the day of 29

, 30thor

can not be specified, but the specifying the end of the month conducts clearing at the end of the

month. The result of clearing can be selected for printer output or file output.

● Calculation for specified date The charge may be calculated for any desired period covering 122 days from and including the former day. (The standard charge is not included.)

Month end specified

Specify when the end of the month is desired to select. This setting clears based on the operating record until the final day monthly.

Date specified

Specify when a fixed day is

desired for clearing. However,

(3) What is the time frame for charging?

The charge of one calendar day can be set with 5 charge units to 10 time frames divided. This setting can change the charge unit depending on the time frame in the morning, after noon, overtime or weekend. As the charging unit can be set to each measuring instrument individually

, sophisticated operation according to the types of measuring instruments can be performed. However, the setting of time frame should be applied collectively f or each measuring instrument.

In the case of electric power count by PC direct connect (RS-485WHM), charging unit (daytime, nighttime, weekday, weekend and seasons) can be set up.

(4) What is the seasonal charge?

The electrical power charge can be divided into the summer seasonal charge and normal charge. Because of this, the following management can be adapted for example; “As a ratio of using air conditioner rises in the summer (July ~ September) and electric power consumption of a whole building increases accordingly, higher power rate may be applied in this period.” The period of the seasonal charging may be applied by specifying the date of start and end respectively.

[RE: Apportioning of air conditioning power consumption] Since the watt-hour meter value of power consumption is apportioned by judging the operation status of the indoor unit from detailed communication between the indoor and outdoor unit, this value can not be applied to the business certificate legally defined. The same limitation is applied to the case of direct reading of measuring instrument unit. In order to employ this system, therefore, it is recommended to conclude an agreement or contract between the building owner and tenants stipulating that [The air conditioning charge should be collected through appor tioned calculation based on the operation status (including the temporary processing measure at trouble)]. (1) This system does not measure the power consumption of each indoor unit directly. (2) As the system estimates the power consumption of air conditioning, the valued obtained herewith may not be applied to

the certificate of business transaction. (3) Even if the operation time of air conditioners is same, the power consumption differs depending on the operating status. (4) As air conditioners are powered even when they are stopping, the power consumption will be charged. (5) One watt-hour meter should be connected to one air conditioner. If connected to plural air conditioners, an error will be

caused due to the apportioning of total power consumption. (6)

At the failure of PC, G-50A or PLC, the average apportioned value in the past may be adapted for temporary transaction as a solution. (7) As the power consumption and gas consumption is taken in the form of a pulse, the performance and accuracy are

depending on that of the measuring instruments employed. Under this circumstance, we are not liable for the

performance and accuracy presented. (8)

As the resultant air conditioning charge is rounded to the nearest whole number at a figure not shown here, please

note that an error generates between the air conditioning charge of watt-hour meters and that of the block total.

CAUTION

8.2 Selection of Charging Function

The G-50A system provides the following 3 methods to calculate the charge by measuring instruments. For the objective models that can be charged by each method, please refer to Table 4-3.

(1) Manual input of electric power consumption

This method is only applicable to the charging of electric power consumed by air conditioners . Without using a watt-hour meter, this method calculates electric power consumption in a ratio of each tenant (charge block) by using the daily operation amount and the set capacity of the air conditioner. Utilizing the electric power apportioned charging calculation tool of the integrated software, the reading value of the watt-hour meter of the outdoor and indoor units is input manually to calculate the air conditioning charge. As the standard charge can not be set by this method, it should be added by the user.

(2) Watt-hour meter pulse counting (Apportioning method)

This method is only applicable to the charging of electric power consumed by air conditioners . By apportioning the electric power measured by the watt-hour meter connected to the air conditioner and the daily operation of the air conditioner, the electric power consumption per tenant (charge block) can be calculated by this method.

(3) Measuring instrument pulse counting (Direct reading method)

This charging method covers the Free Plan LOSSNAY for which the above apportioning method is not available, the air conditioning electric power of A-control models, the general electric power of lamps and plug sockets, and the charge of city water. In such cases, you are kindly requested to install a measuring instrument for each charging block for charging in a unit of measuring instruments.

(4) Electric power count by PC direct connect (RS-485WHM)

This charging method is only applicable to the charging of electric power consumed by air conditioners. By apportioning the electric power measured by the watt-hour meter connected to the air conditioner and the daily operation of the air conditioner, the electric power consumption per tenant (charge block) can be calculated by this method.

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.

(4) TG-2000A

By collecting charging information from PLC and G-50A, the TG-2000A conducts the apportioning calculation of these data during AM 4:00 ~ 7:00 once a day. As the electric power consumption collected from PLC represents the integrated value, TG-2000A takes a difference with the electric power consumption of the previous day and holds the data converted in the daily power consumption. On the clearance day, the daily apportioning data is added and the standing charge is also added for clearing.

8.4.2 Apportioning calculation method of outdoor unit

The apportioning calculation method when a watt-hour meter is installed on the power source line of outdoor unit is shown here taking Figure 8-10 as an example.

(1) Decision of outdoor unit apportioning calculation method

The calculation method differs depending on the processing ways of electric power consumed by the crankcase heater which is the waiting electric power of the outdoor unit. The processing methods include the mode 1 ~ mode 3 required to be set on TG-2000A. Mode 1: Apportioning including crankcase heater portion Mode 2: Apportioning calculating crankcase heater portion separately (Default value) Mode 3: Apportioning not including crankcase heater portion

(2) Decision of apportioning standard data

The apportioning standard data of the indoor units used by each tenant (charge block) can be selected from the following two methods. (Selection by TG-2000A) These data are integrated by G-50A for each indoor unit per charging time frame and collected by TG-2000A once a day. 1 Standard data 1: Capacity saving amount (default) ⇒ Integrates power consumption corresponding

The standing charge is only added at calculation on the clearance day, and printed out after summing up the air conditioning charge. Printing out is not available for the calculation of specified day.

CAUTION

(3) Apportioning by apportioning standard data

To calculate [Power consumption per indoor unit], multiply the operation time by the standard data being calculated for each indoor unit per charging time frame with each capacity. Sum up this [Power consumption per indoor unit] for the indoor units inside the watt-hour meter to obtain [Indoor unit total power consumption]. Using a ratio of these two data, calculate [Daily power consumption by indoor unit] once a day.

(4) Processing on clearance day

On the clearance day, sum up [Daily power consumption by indoor unit] for each tenant (charge block) and add the standing charge to calculate the monthly electric charge.

8.4.3 Apportioned calculation of indoor unit

Figure 8-10 shows an example of apportioning method when a watt-hour meter is installed on the indoor unit power source line.

(1) Decision of indoor unit apportioning mode

First decide to carry out the apportioning of indoor unit or not. When a watt-hour meter is not connected to the power source line of indoor unit, set to [No apportioning]. No apportioning: The electric power consumption of indoor unit will not be apportioned. Apportioning : The electric power consumption of indoor unit will be apportioned by “Integrated time

× Fan capacity When “Apportioning” is selected, [Power consumption per indoor unit] is integrated for each charging time frame per indoor unit by dividing it into [Auxiliary heater power consumption] and [Fan power consumption]. For the models without auxiliary heater, [Fan power consumption] = [Power consumption per indoor unit] is applied. For the auxiliary heater and fan operation time, G-50A collects it from the indoor unit in a cycle of 1 minute.

(2) Apportioning calculation of indoor unit

[Power consumption per indoor unit] integrated for each indoor unit per charging time frame is summed up for the indoor units in the watt-hour meter system to obtain [Total power consumption of indoor units]. Using a ratio of these two data, [Power consumption] per charging time frame collected from PLC or RS-485WHM is apportioned once a day.

(3) Processing on clearance day

On the clearance day, sum up [Daily power consumption by indoor unit] for each tenant (charging block) and add the standard charge to calculate the monthly electric charge.

8.4.4 Manual input of electric power consumption

The calculation method of manual input not connecting watt-hour meter is given below. With this method, calculation is performed by employing the reading value of watt-hour meter without using watt-hour meter or PLC itself.

Using “Charging ratio support software,” enter the reading value of watt-hour meter, and apportion it for each tenant.

PC for centralized control (Integrated software)

(1) Standard charge

This method can not process the standard charge as its sole function is to calculate air conditioning charge based on the operation data. The standard charge should be added by the user additionally.

(2) Air conditioner charge

The air conditioning charge of each tenant can be calculated by using “Charging ratio support software (EXCEL)” locating in the Integrated software install CD-ROM. For the parameters required to calculate the charge, use “Apportioning parameters” and “Charging ratio” explained in the Items 8.4.2 and 8.4.3. By employing the file prepared by the integrated software based on these parameters (CSV file) and the manual input of the electric power consumption of indoor/outdoor units, the air conditioning charge per charge block (tenant) can be calculated by using a calculation software like “Charging rate support software.”

(3) Apportioning parameters of outdoor unit

As explained in the item 8.4.2, calculate the value by using the indoor unit rated capacity for each indoor unit per charging time frame, and total the value multiplied by the unit price for the charging blocks, and then calculate a ratio to the total of all blocks.

(5) Charging ratio support software

By using “Charging ratio support software” (EXCEL) provided with the integrated software, the charge apportioning and bill preparation for each tenant can be performed. Through the reading of the operation time data file prepared by TG-2000A from the menu screen of the charging ratio support software, automatic calculation will be carried out. By inputting the reading value of each watt-hour meter manually, apportioning calculation will be performed. A bill can be automatically prepared by merely selecting the tenant name.

For the data file of operation amount, CSV

file created on the clearance day automatically or that output from the air conditioning charge confirming screen can be used. The file output can be changed freely. (Default value: C:¥TG-2000A¥Chr¥Chargefile¥)

8.4.5 In the case of measuring instrument pulse counting (direct reading) method

The measuring instrument pulse counting (direct reading) method is explained here. For this method, charging is practiced only by the measuring instrument value collected by PLC. Therefore, a measuring instrument is required to install for each charge block (tenant). It is required to prepare PLC, the pulse counting software and the license registration of all G-50As

(1) Standard charge

The standard charge is calculated by referring the contract rate of electricity, gas and city water and set to TG-2000A for each measuring instrument.

(2) Unit price

For the unit price, the electricity may be set in 2 types (Electricity 1 and Electricity 2), and gas, city water and calorific amount be in 1 type. However, the time frame is set to all measuring instruments collectively.

(3) Charge

In this method, the charge may be calculated by multiplying the values of the measuring instruments provided by the unit price and further adding the standard charge.

In the case of the measuring instrument pulse counting method, the operation information of air conditioners is not required, but the license registration to G-50A is essential.

8.5 Output of Charging Data

Thanks to the use of TG-2000A, the apportioned result and power consumption can be output per each watt-hour meter, unit price

8.6 Charging Method

As shown below, the charging in this system can be set as follows. Divide the time frame 0:00 ~ 24:00 into 10 charging frames, and assign 5 charging unit prices to each charging frame respectively for setting. Please note that each setting is common within the system.

Charging can not be made without this setting.

In the case of electric power count by PC direct connect (RS-485WHM), charging unit (daytime, nighttime, weekday, weekend and seasons) can be set up. Setting will be different from Figure 8-15.

8.7 Caution for Using Charging Function

Please observe the following points when using the charging function.

(1) Caution for each control/setting

●● When using the charging function (power apportioned charging), make sure to conduct clearing

process before setting or modifying the system composition, monitoring display setting, and charging system setting. When any item has been modified, the setting of the charging system should be modified or identified.

●● About the time setting

Since the change of time affects the power apportioned calculation of air conditioning charge, do not practice it frequently in waste. (Suppress the frequency of time adjustment to once a month or the like.) For the time setting, use the time setting function of TG-2000A. Never attempt to conduct to change the setting by Web browser or “Property of clock and time” of Windows.

(2) Caution for air conditioning charge

●● To use this charging function (power apportioned charging), it is recommended to conclude an

agreement between the building owner and tenants stipulating that the air conditioning charge shall be collected by the apportioned charging based on the operation records (including temporary measure taken at trouble).

●● To prevent the stopping of integrated software or the destruction of data at power failure or

instantaneous power stoppage, recommend to install an uninterrupted power source system. (Recommended Model: Mitsubishi Electric FERQUPS-A series)

●● It is recommended to keep the result of air conditioning charge in other way than storing in the

centralized control PC. (for example to print on paper)

●● The registration of charge license to G-50A unit is required for all units registered to the centralized

control PCs. Without the registration, the air conditioner charging function does not operate normally. (All of the G-50A requires Web monitor license registration.) Please refer to section 2,3 for function licence.

(3) Calculation of air conditioning charge

●● The calculation method of air conditioning has originally been developed by us where the

apportioning parameter is calculated judging from the operation state of the air conditioner. For this reason, it differs far from the system installing a watt-hour meter on the power supply site of each air conditioner. If plural outdoor units are apportioned with one watt-hour meter, the calculation will be carried out regarding the plural units as a one large outdoor unit. Here the COP of each outdoor unit will not be taken into consideration.

●● When trouble is occurred on the system, such measure will be taken as to forward the apportioning

calculation to the next day or not to conduct the apportioning calculation. To modify the apportioning data, use the function “Data maintenance of charging.”

●● In the case of the power consumption PC direct reading (RS-485WHM) system, the corresponding

power consumption can not be apportioned or counted when a WHM generates trouble. Please use the function of [Maintenance of charging data] in such case.

●● Since the air conditioning charge is calculated in a unit of charging block, the indoor units not

registered to the charging block will not be reflected to the air conditioning charge.

●● As the resultant air conditioning charge is rounded off at a figure not shown here, please note that an

error will be induced between the air conditioning charge of watt-hour meters and that of the total blocks.

9. Step 6: Energy Saving/Peak Cut Control

Here the energy saving control or peak cut control to be performed by G-50A is set. This setting is essential in conducting the energy saving control or peak cut control. As this function is optional, the license registration to G-50A is necessary to use. A different license should be applied to the energy saving control and peak cut control respectively, the license for your desired usage should be registered.

Notice

●● For PLC, the pulse counting software (Ver. 1.01 ~ ) used for the power apportioning

function can be applied. (Pulse counting software: PAC-YG11CDA, etc. installed)

●● For the pulse counting software used at peak cut control, employ that Ver. 1.01 or

later.

●● For the peak cut control, use one set of watt-hour meter for each G-50A.

●● The peak cut control license contains the function of energy saving control.

●● Peak cut control is not available in RS-485WHM system.

[Re: Energy saving/peak cut function]

●● During the use of the peak cut function, any damage such as the exceeding of

power consumption than the contract demand should induced due to the trouble of G-50A or PLC, such damage will not be indemnified, for which your kind understanding is requested.

For the block with temperature difference between set and inlet temperature exceeding the set, the energy saving control set at level 0 is not applied. The integrated software sets the following energy saving items and energy saving time to G-50A per outdoor unit and the set G-50A conducts the energy saving operation for the outdoor unit. Connecting the watt-hour meter (PLC) allows conducting energy saving operation meeting the power consumption. The control object and detail are same as that of the energy saving rotated control. One set of the watt-hour meter can be set for each G-50A. During the energy saving control, the energy saving mark is displayed on the air conditioner group icon of Web, integrated software. Daily power consumption and control level can be monitored by the integrated software. G-50A can hold the data for 3 days max. including that of today, yesterday and the day before yesterday. Monthly power consumption can be monitored by the integrated software (for 62 days max.). The integrated software monitors from PLC for display and storing.

(1) Energy saving control for indoor unit

For the energy saving control for the indoor unit, select the time portion to be applied to the energy saving control items listed in Table 9-2 from 0/3/6/9/15/30 minutes. By dividing those items by the group numbers in the operation block evenly, the energy saving control is applied to the groups starting from that with smaller group number in order. When “30 minutes stopping” is being applied to save energy, ON/OFF operation can not be performed by any controller.

Notice

●● In the case of the block setting stepped across from TG-2000A to G-50A, only the unit

controlled by the G-50A is set as the block on the G-50A. Here each G-50A applies rotation control to each group inside the block.

●● When the fan/thermostat OFF control is selected, Free Plan models and A-control

Slim models are provided with the thermostat OFF (capacity saving control) command, while K-control models with the fan mode switching. As the mode display of the local remote controller does not change, energy saving control can be performed without the perception of occupants.

●● Setting of the energy saving ineffective temperature difference allows not applying the

level 0 control to the block with the temperature difference between inlet and set temperature exceeding the set value.

●● Operation control from Web browser or TG-2000A provides the screen display of [ON]

for 1 minute maximum but not allowing to run the air conditioner.

●●

The capacity saving control is a control to suppress the maximum value of the outdoor unit. Therefore, no energy saving effect can be obtained under the setting to 80% if the operation is conducted with the capacity below 80%.

●●

In the case of the energy saving control, capacity saving control is applied to the outdoor unit individually. For this reason, be careful that the control will be applied to the indoor unit being not targeted if the group setting is made by stepping over the refrigerant system.

●●

In the case of capacity saving control to the outdoor unit, control for a short time may not provide a normal effect. Control for 30 or 15 minutes is recommended.

●●

For Multi S, set to “No control” so that the capacity saving control will not be applied to the outdoor units.

9.2.2 Peak cut control

(1) Explanation of function

Connecting the watt-hour meter (PLC) allows conducting the energy saving control of Table 9-2 divided into 5 levels (Level 0 ~ Level 4) by estimating the power consumption for 30 minutes. Meantime, the control level is judged with an interval of 1 minute, and the control of higher level is applied in accordance with the measured power consumption for the past 30 minutes and estimated value.

[How to obtain the estimated value] Estimated value (kW) = Power consumption in the past 5 minutes (kWh)

× 6 (Power consumption for 30 minutes) × 2 (kWh → kW <30 minutes> converted) ----- 1

In Figure 9-5 for example, it is assumed that the control at the energy saving level 1 is being conducted in accordance with [Power consumption for the past 30 minutes]. In this occasion, the estimated value after 30 minutes is calculated from [Power consumption for the past 5 minutes] by Equation 1, it reaches the region of energy saving level 2. In this case, the energy saving control set at the energy saving control level 2 will be carried out. By making the energy saving ineffective temperature difference effective, under the control of Level 0, when the temperature difference between the set and inlet temperature is exceeding 3°C~9°C (able to set in a unit of 1°C), It is possible not to allow conducting the energy saving control set at Level 0 in consideration of comfort. (The control set at Level 1 ~ Level 4 will be conducted regardless of the temperature difference.)

By setting the target demand value and [Stopping control for 30 minutes] of the energy saving control item, the peak cut control can be practiced as an application of the level control above.

CAUTION

Notice

● When status is monitored, only the air conditioning group under energy saving control will have icons displayed as shown in the Table 9-5.

● Power saving control of outdoor units will not make the energy saving symbol displayed with air conditioning group icon, since it is unknown whether the outdoor unit has energy saving operation at that point in time.

Figure 9-7 Peak cut status history daily report example

9.4 Energy Saving Control System Design Flow

Following is the outline of the system design flow for energy saving control execution.

(1) Determine the license type.

If you try to have a peak cut control by calculating power consumption from a watt-hour meter, you will need to have a separate PLC (with a pulse count software installed). A peak cut control license will be required for this. If you do not implement a level control, you don’t need to arrange a PLC, or to decide a demand level. In this case, you will need to have an energy saving control license. If you do a peak cut control, you will set the Watt-hour meter in increments of G-50A. The control level will be set at 5 steps. As a concept, you will consider the target contract demand based on the current contract demand, and determine the value for the final level (Level 4). Then, you determine the figure at each level leading up to Level 4. [Example] Level 0: ~ 200 kW

Level 1: 200kW ~ 500 kW Level 2: 500kW ~ 800 kW Level 3: 800kW ~ 1000 kW Level 4: 1000kW ~

(2) Select the energy saving control method.

As an energy saving control method, you choose either [energy saving control using indoor units] or [energy saving control using outdoor units], or both. [Example] Use both indoor unit energy saving control and outdoor unit energy saving control.

(3) Confirm the energy saving area.

The energy saving control of indoor units is done through a rotation control of the group operation based on the unit of operation block. The energy saving control of outdoor units is done by rotating the operation of the outdoor unit in numerical order of the address. The control order is sequenced from a smaller number given to the group. First, you confirm the order of control within the operation block. [Example] In the figure shown on the right, Group 1 to Group 6

belong to the same operation block (Office A). In this case, Group 1 and Group 2 on the window side will be controlled consecutively. Compared with the Group 5 and Group 6 side of the room, the temperature in the window side goes up temporarily (in summer). By rearranging the groups you can provide energy saving control without too much sacrificing comfort. In this case, Group 4 should become Group 2, Group 5 should become Group 3, Group 2 should become Group 4, and Group 3 should become Group 5. By doing so, you can avoid two window side units having energy saving control at the same time and improve the comfort level.

(4) Determine the control details.

Determine the energy saving control details for each operation block and outdoor unit. If you set both indoor unit energy saving control and outdoor unit energy saving control within a particular level, both controls will be multiplied. [Example]

Level Level 4 1000 ~ kW Level 3 800 ~ 1000 kW Level 2 500 ~ 800 kW Level 1 200 ~ 500 kW Level 0 ~ 200 kW

Step 7: Selection of Measuring Instruments

(1) Measuring instruments

Use measuring instruments with recommended pulse signals shown in the Table 10-1 below. We also recommend using a watt-hour meter shown in the Table 10-2 below.

●● Make sure pulse unit is set in the measuring instruments. If not, consumption will

not be correctly measured, and charging functions and peak cut control will not work correctly.

●● Power and gas consumption is counted by pulse. We will take no responsibility for

measurement results since they depend on performance and accuracy of measuring instruments.

Step 8: General Purpose Equipment Control

TG-2000A can control and monitor system equipment. By using general-purpose control functions, you can control and monitor other manufacturer’s air conditioning units, lighting fixtures and other system equipment as well as water level of a water or fire tank with a flooding/low level alarm on the TG-2000A monitor screen. System equipment is controlled by PLC. “General-purpose control software: PAC-YG21CDA” needs to be installed in PLC. (For PAC-YG21CDA Ver.1 series, no licensing registration needed for G-50A.)

●● Operation and monitoring of general purpose system equipment cannot be

controlled if the PLC or other equipment fails. Take this into consideration, and make sure you provide a circuit for a switch for an emergency stop/start. Do not use it for monitoring the system affecting human life. In case you do, incorporate an alternative safety mechanism.

11.1 Outline

PLC will be used to control general-purpose equipment, along with a DI board (DC input unit) and a DO board (transistor output unit). One icon will be shown on the TG-2000A monitor screen to represent one system equipment, and you can operate (one shot pulse output), monitor the status, and monitor for error (level input). Therefore, you will be using two terminals on DO board and two terminals on DI board for one system equipment. For status monitoring, you can choose the name of the status, and for error status, you can choose the name of the error and its icon color.

11.2 System Design Method

System design method for general-purpose control is outlined below.

11.2.1 Listing up of general-purpose equipment

General-purpose equipment needs to be listed up. Control and monitoring of general-purpose equipment will be done through contact control using PLC. Therefore, the equipment to be controlled should have the following signal specifications. TG-2000A can only operate or only monitor the equipment, in that case, unused terminals should remain unconnected.

11.2.2 Determine the control items.

After you determine the equipment to be connected, define the control items for each equipment. For instance, whether you want to operate the instrument (ON and OFF) and monitor it, including error monitoring, or just watch for failure (malfunction). For ON and OFF, status output signal from the instrument changing the icon status (color) is the basic

mechanism.

*When the system instrument does not provide the output of operation status, connect to the input of operation status by installing a self-

holding circuit.

The error signal from the system instrument will turn this to the error status display.

If the status is OFF, operate and send the ON signal from the system instrument. The status will change to ON.

11.2.3 PLC assignment

After you determine the control items of the connected instrument, assign PLC terminals. General-purpose control PLC needs to have one DI board and one DO board mounted regardless of the control items. (There are certain restrictions about the mounting location and others. Refer to 12.3 for details.) Table 11-3 shows the general-purpose control PLC terminal assignment. Since each terminal in PLC has a pre-determined function, keep the terminal un-connected (open) where the signal is not to be used.

11.2.4 Required materials

Members required for general-purpose control are listed in the Table 9-3.

Step 9: Determining Number of PLC Units

This chapter talks about how to determine the number of sequencers (PLC).

12.1 PLC Standard Configuration

G-50A uses PLC (Programmable Logic controller) to provide measuring instrument charging function (pulse count system), general-purpose control function and other functions. The PLC to be used is “MELSEC-Q series” by Mitsubishi Electric, and Figure 12-1 shows the standard configuration of G-50A system. In the standard configuration, “power supply unit”, “CPU Unit”, “Ethernet Unit” are mounted in the slots above the base unit. Two open slots should be mounted with boards (DC input unit and transistor output unit) necessary to realize various functions. Model names of MELSEC-Q series products are listed in the Table 12-1 below.

12.2.1 Restriction on the number of units

To carry out measuring instr ument charging function or energy saving peak cut control, you will need to have the standard configuration explained in the previous chapter plus a DC input unit. One DC input unit can support 16 contacts, so you can connect up to 16 measuring instruments. Since one PLC has two open ports, you can connect 32 watt-hour meters to 2 DC input units. In case 33 or more watt-hour meters have to be connected, add one more PLC unit.

12.2.2 Terminal connection diagram

Connection to DC input unit (QX40) terminals is shown in the Figure 12-3. Since DC input unit is non-voltage input, you need to prepare an external DC24V power supply (DC12V is cannot be used).

When performing general-purpose functions, you will need the standard composition explained in 12.1, DC input unit, and transistor output unit. DC input unit and transistor output unit each supports 16 contacts. One system instrument uses two contacts, so, up to 8 general-purpose units can be connected. When you connect 9 or more generalpurpose instrument, you will need to add one more PLC unit.

they do not perform properly. Please mount the units referring to the diagram above.

CAUTION

12.3.2 Terminal connection diagram

Figure 12-5 shows the connection to terminal boards in DC input unit (QX40) and transistor output unit (QY40P). Since DC input unit and transistor output are non-voltage, you have to provide a DC24V power supply (DC12V is unacceptable) and a DC24V or DC12V power supply for transistor output unit separately. If the facility instrument side has a level input, you have to prepare a pulse-level conversion circuit separately, as shown in the figure 12-6.

13.2.1 Setting method for connecting G-50A to exclusive LAN

This is a setting method to establish G-50A system with exclusive LAN wiring

(1) Setting of IP address

In the case that LAN wiring is newly provided for G-50A system, allocate the IP address of G-50A from [192.168.1.1] in sequence. For example, assign [192.168.1.1] for the first G-50A, [192.168.1.2] for the second G-50A, and so and so in sequence. In addition, set a PC for monitoring on the Web to monitor G-50A and set the initial setting tool and the like also to the network address in the same system. In case of G-50A exclusive LAN, it is recommended that the IP address of each component is set within the following IP address range. As the default value of IP address for G-50A is [192.168.1.1], the address from the second G-50A must be changed.

(2) Setting of subnet mask

Set [255.255.255.0] (default value) typically.

* Some models among hubs are provided with exclusive port for connecting between hubs. For G-50A and PC for monitoring, connect to the regular port.

13.2.2 Setting method for connecting G-50A to existing LAN

(1) Case of central monitoring by Web browser

In the case of installing G-50A system in the existing LAN wiring, consult your network administrator who manages the LAN system to set IP address, subnet mask, and gateway address. Meantime, gateway address can be set only with the initial setting tool.

(2) Case of centralized monitoring by TG-2000A

In the case of using the peak-cut function and charging function by means of TG-2000A, the separation of system by a router is recommended. This is a means to secure the reliability of each component, as various signals are being transmitted on a LAN system in the environment that many PCs for clerical work are installed on the existing LAN system. Communications with G-50A and PLC are possible by making a router convert the address by assigning an IP address corresponding to the IP address form on the backbone LAN also to G-50A and PLC to access to them by the use of the address. G-50A installed in the downstream of a router is required to register the address of the router as a gateway address, but PLC-related devices are not required to.

Notice

● Since the transmission speed of analog line is slow, the use of ISDN line or PHS line is recommended.

● ADSL system is of analog originally. In ADSL system, however, data are transmitted, separated for data communications and for telephone communications by the use of a device called splitter to separate data side from telephone side. An ADSL modem is connected to the data side of ADSL. But telephone from outside is not connected with the modem, because dialup connection is not possible with the modem. Connection to telephone from outside in ADSL system is now under consideration.

In order to use analog line, fit up the router with a modem. (Refer to Table 13-7 for recommended modem card)

In order to accept data to arrive on analog line in remote locations on ISDN line at site, fit up the router with a modem card. (Refer to Table 137 for recommended modem card)

(1) Setting of dialup router

Set the dialup router so as to connect received call (data communication) via public telephone line to the LAN side. And then, set an IP address to be assigned to the dialup router and PC in remote locations. The IP address of the dialup router is recommended to be [192.168.1.254] and the IP address of a PC to be assigned to the telephone line in remote locations is recommended to be [192.168.1.211]. Also, the IP address of the PC to be assigned to LAN must be set to [192.168.1.*] so as not to be the same IP address as used in the system at site.

(2) Network setting of G-50A

Set the IP address, subnet mask, and gateway address of G-50A by means of the initial setting tool2. As for gateway address, set the IP address of the dialup router.

IP address: 192.168.1.101 Sub-net mask: 255.255.255.0 Gateway: No setting

As the IP address of telephone line is [192.168.1.211], set the IP address of PC to [192.168.1.211] so as to avoid competing against each other.

Example: 192.168.2.1

* The IP address of dialup router is recommended to be set to [192.168.1.254]. For setting method for IP address, refer to Instruction Manual for Dialup Router. * In case of using a dialup router without modem function, a modem (for analog and for ISDN) is required to be connected between the dialup router and public switched phone network.

Figure 13-5 Setting example of remote monitoring system

In case of setting to the same system, data communications are not available by way of the dialup line, because telecommunications data are input from the LAN port of the PC.

A gateway address can not be set only from the initial setting tool. (Other addresses can be set from G-50A.)

13.4.1 Preparations before performing abnormal mail transmission

(1) Making a contract with an Internet provider to transmit mails at the side of a customer

Contact with an Internet provider. (Except for the case that a private LAN system in an own company’s building and the like is provided with a mail server.) After the contract, a provider contract document specified an access point, user ID, authorized pass word, etc. is sent to the customer. This contract document is necessary for the setting of G-50A and dialup router.

(2) Obtaining information on IP address for a mail server

The IP address of a mail server may be described in the provider contract document, but it seems that most of providers don’t open any IP address. In such a case, obtain information on the IP address of the mail server in the following procedures. Connect to the access point by using the function of dialup of a PC for monitoring to establish an environment where the Internet is available. Then, execute MS-DOS Prompt (Command Prompt in Windows 2000/XP) in the state of provider being connected. And then, input [Name of Mail Server (name of SMTP server) for PING transmission1] in the MS-DOS Prompt to execute, and information on the IP address of the mail server is available.

(3) Abnormal mail transmission license registration

To use abnormal mail transmission, it requires license registration. Please refer to section 2,3 for function licence.

13.4.2 Setting to perform abnormal mail transmission

(1) Setting of dialup router

Set the telephone number of provider’s access point, ID for connection, and pass ward obtained at the time of contract with a provider to the dialup router.

(2) Network setting of G-50A

Set the IP address, subnet mask, and gateway address of G-50A by means of the initial setting tool. Set the IP address of a dialup router to gateway address.

(3) Mail setting of G-50A
