1 Introduction A special feature of Mitsubishi Electric Corporation’s “Central Controller G-50A” and "Central Controller GB-50A" are that a PC connected to a LAN can be used to monitor the operation condition of air conditioners, perform air conditioner operations, and make initial settings. This document explains the procedures for making initial settings for the Central Controller G-50A using the web browser.
2 Setting the Operating Environment Given below is an explanation of the PC settings and web browser settings that are required for using a web browser to monitor air conditioner units and perform operations. 2-1 Setting the PC IP Address You need to set an IP address on the PC that will enable you to connect to the G-50A using a web browser. For instance, if the G-50A IP address is [192.168.1.1], the PC IP address will need to belong to the same system (for example [192.168.1.101]).
(4) In the [Internet Protocol (TCP/IP) Properties] dialog, click [Use the following IP address] and enter the IP address (for example, “192.168.1.101”) that you want to set in the IP address field. You normally set [255.255.255.0] as the subnet mask. Note: Ask your LAN administrator to provide the IP addresses and subnet mask. (5) Click the [OK] button to close this dialog, and then close the other open dialogs to complete the network setting.
2-2 Setting the Web Browser Perform the necessary web browser settings to enable the web browser to connect to the G-50A. Note: The settings and screen images used as examples in this manual are based on Internet Explorer 6.0. 2-2-1 Not connecting to the Internet If the PC you use for monitoring air conditioners and performing operations is not going to be connected to the Internet, use the procedure given below to set the web browser environment settings.
2-2-3 Connecting to the Internet using a proxy server (Using an existing LAN) If the PC you use for monitoring air conditioners and performing operations is going to access the Internet via proxy server by connecting to an existing LAN such as a LAN within your company, use the procedure given below to set the web browser environment settings. By performing these settings, your PC will connect to a proxy server only when connecting to the Internet.
3 Performing Operations Given below is an explanation of how to connect to the G-50A and how to make various settings for the G-50A. Note: If the G-50A is restarted due to circumstances like a power interruption, wait until the screen on the G-50A main unit displays the normal operation screen (it takes several minutes before the normal operation screen is displayed) before using a web browser to access the G-50A.
4 Initial Settings 4-1 Setting the Current Date and Time Click [Initial Settings] in the menu, and [Date and Time] screen will appear on the screen. Enter the current date and time, and then press the [Save Settings] button to send the current date and time to G-50A. Note: If the user logs in as a building manager, the operations may be prohibited. Note: If the system is connected to the TG-2000A, make all settings and changes from the TG-2000A so that the data in TG-2000A and G-50A will match.
4-2 Setting the Basic Information and External Input Functions Display the page needed to perform the G-50A basic setting by clicking [Initial Settings]-[Basic System] in the setting menu pane. On this page, you perform the basic setting such as the G-50A unit name, network setting and M-NET setting. Click [Save Settings] to send setting data to the G-50A. After the setting data are sent to the G-50A, a message will appear asking whether or not to restart the G-50A.
4-2-2 M-NET Setting In M-NET Setting, set the G-50A M-NET address, whether or not a K-Control unit is present and which machines send the prohibited controller command. (1) Enter the G-50A M-NET address in the [M-NET Address] field. Normally you should enter [0]. (2) When K-Control air conditioners are connected, click [Used] in the [K-Control Units] field and enter the M-NET address of K transmission converter in the [K Converter Address] field.
4-2-3-1 Settings for when the G-50A is connected to a dedicated LAN (1) Enter the G-50A IP address in the [IP Address] field. If the LAN wiring has been newly set up, allocate IP addresses to the G-50A units in a sequential order starting with [192.168.1.1]. For example the first G-50A unit will receive an IP address of [192.168.1.1], the second G-50A unit will receive an IP address of [192.168.1.2] and so on.
4-2-3-2 Settings for when the G-50A is connected to an existing LAN When connecting the G-50A to an existing LAN, consult with the network administrator who is responsible for the LAN before setting the IP address, subnet mask, or gateway address. [Example of a Permanent LAN System] Backbone LAN Gateway IP: 10.130.1.250 Gateway IP: 10.130.2.250 Receive from the LAN administrator. G-50A IP Address Subnet Mask G/W Address Receive from the LAN administrator. Web Monitor PC Web Monitor PC :10.130.1.
(4) Selecting [ON/OFF/Prohibit/Permit (Pulse signal)] makes it possible to use pulse signals to run multiple units, stop multiple units, prohibit local operation and permit local operation. In this mode, it is possible to freely operate the remote control except during the pulse signal input. 1 2 3 4 5 6 7 8 9 Run Stop Prohibit Permit DC12V :Pulse generator Connection to G-50A (CN2) 0.5 - 1.0 Seconds Contact ON Run Contact OFF Contact ON Stop Contact OFF Run Stop 0.5 - 1.
4-3 Group Setting Display the page needed to register the group of air conditioners to be connected to the G-50A and to set the group name by clicking [Initial Settings]-[Groups]. On this page, you perform the basic setting such as the G-50A unit name, network setting and M-NET setting. Click [Set to G-50A] to send setting data to the G-50A. Note: If the user logs in as a building manager, some of the operations may be prohibited.
(2) To register remote controllers in a group, click on the [Remote Controller Registration] field to display the [Select Unit Addresses] screen, and click on the numbers corresponding to the units to be registered. The ones that are selected will be shown with a yellow-green background. To cancel the selection, click on them again. Deselected items will be shown with a gray background. Note: A maximum of 2 remote controls can be registered in one group.
4-4 Interlocked Setting To interlock the operation of LOSSNAY with the run/stop status of the indoor units, click on [Initial Settings]-[Interlocked LOSSNAY] in the menu to bring up the Interlocked LOSSNAY screen, and enter the interlock conditions. Click [Save Settings] to send setting data to the G-50A. Note: If the user logs in as a building manager, the operations may be prohibited.
4-5 Block Setting By performing block settings, multiples of air conditioner groups can be collectively monitored or operated from the Web or TG-2000A. It also enables energy-save/peak cut controls. Bring up the Block Setting screen by clicking [Initial Settings]-[Blocks] in the menu, and register the groups in the block to utilize these features. Click [Save Settings] to send setting data to the G-50A. Note: If the user logs in as a building manager, some of the operations may be prohibited.
