1. Selecting a Computer

Selecting a desktop

• Depending on the function, it is recommended to use desktop as opposed to a laptop computer as there is a tendency for heat to build up in a laptop.

Computer based UPS recommended

• It is recommended to use a UPS to protect data from momentary power outages or power cuts.

Use a computer/operating environment with specifications capable of running the PAC-YG31CDA function.

• Run the function using the specified OS. There is a possibility that the function cannot be used when running an OS other than specified.

• Use a business model computer. There are cases when it is not possible to install or run the application with other application on a computer or laptop intended for personal use.

2. Precautions for General Usage

Do not place the computer in any of the following locations.

• An error or accident may occur when using in the following environments.

place where there is: a lot of dust, a likelihood of shock o vibration, instability, a heater or speaker nearby, direc exposure to sunlight, a likelihood of dropping, a possibilit that the computer may be exposed to moisture or high temperature, or where it may be exposed to sudden temperature fluctuations or heat.

Ensure to read the computer/peripheral instruction manual.

• A fire or accident may occur due to improper use of the

equipment.

void covering the computer or AC adapter with a cloth or blanket, or locating them on or near heater.

• There is a possibility of internal temperature build-up, fire or

burning under the above situations.

Do not close the lid when using a laptop.

• There is a possibility of an internal temperature build-up, fire or burning. Use in an area with sufficient ventilation.

Do not touch the computer air vent.

• The air emitted by the ventilator is hot and may result in burning if exposed to the skin.

Cut the power or disconnect the power cabl immediately if smoke, or an abnormal smell or nois emanates from the computer.

• Using the computer in the above circumstances may result in fire, burning, or electric shock. Please consult the maker o the equipment/computer.

Do not tamper with the computer fan.

• Tampering with the computer fan may result in a temperature build-up, fire, or accident.

Use the hard disk, floppy disk, or CD media as indicated.

• Do not expose the hard disk, floppy disk, or CD to shock or vibration during use.

• Do not cut the power or reboot the computer while the hard disk, floppy disk, or CD is in use.

• Always turn OFF the power when moving the computer.

3. Other Precautions

Precautions relating to the computer and peripheral equipment

• Please consult the maker regarding damage to the computer or peripheral equipment. We will not be held responsible fo damage occurring at the user’s site.

2.3 Restrictions

The following restrictions apply to the BACnet IF program.

(1) System configuration limits

Number of units Note

G-50A Max. 10 units G-50A Ver. 2.50 or higher Indoor unit Max. 50 units/G-50A Max. 500 units (including all IC, KIC, AIC, LC*1 , and FU)

[Symbol] IC: Indoor unit, LC: LOSSNAY, FU: OA processing unit, AIC: “A” controller,

KIC: “K” controller

*1 It cannot manage, when being set up so that LOSSNAY may be interlocked with an indoor unit.

Checking the G-50A version Check the centralized controller G-50A version. Update if it is not the applicable version.

Method 1: Using the initialization tool The version can be monitored from the Basic Setting window. Method 2: Using the G-50A main unit

Press the [↑][↓] buttons for two seconds or longer to open the Initialization Mode

Menu window. Then［］button to open the second menu window. The version will

appear at the lower right. * If the integrated centralized control software TG-2000A has already been installed, the G-50A version can be confirmed with Operation Manual TG-2000A.

Updating the G-50A Update by the Update Program CD (for G-50A).

(2) Correspondence at the time of abnormalities

・For the period under reboot of PC, failure of G-50A, etc., neither each control nor a function may operate normally.

(3) Operation at the time of a power failure

・If a power failure occurs, the power supply of a PC will also fall. When the power restores, it is necessary to turn on and start a power switch again. Use of UPS is recommended in the place where a power supply state is unstable.

(4) Function description

・The function/specifications may partially change and improvements may be made without any notice.

Note: ・The BACnet license number must be registered in each central controller G-50A to use this software

BACnet IF.

・Make sure that the license number corresponding to use is registered in the central controller G-50A.

3.3 Group Configuration

In BACnet IF, a G-50A number + group number is a unit for management. The instance number of BACnet consists of G-50A number + group number + member numbers. For details, it is "Chapter 4.3 Relation between object and management item" reference. Below, a group number and G-50A number are explained.

1) G-50A number This is set up with a Setting Tool program.

The ranges of the G-50A number are 1-10.

2) Group number

Two or more sets IC (Indoor Unit) are set up as one group.

The ranges of the group number are 1-50.

3) Member number

This corresponds to each function (operation and monitoring of air conditioning). The ranges of the member are 1-99.
