Page 109: Accessing Acp Lonworks
Installing ACP Lonworks Accessing ACP Lonworks User may control the functions of the ACP Lonworks using LG ACCS program of the ACP Lonworks in the computer connected to the ACP Lonworks through network. LG ACCS (Advanced Centralized Control System) is the ACP Lonworks function control program developed in Java language.
Page 110 Installing ACP Lonworks - If the following page is displayed, install Java according to the figure. - Click ‘here’. - Click ‘Agree and Start Free Download’.
Page 111 Installing ACP Lonworks - Click ‘Run’. - Install by clicking ‘Install’. CAUTION • It is recommended to install with 7 or later which is the current Java version. (Lower Version may not run properly.)
Page 112 Installing ACP Lonworks - When the program is installed, the following screen is displayed. At this time, press Run. If you don’t want to see this message again, check in “I always trust the contents of this poster”. - Click “Run” button. - When the program installation is completed, the log in screen is displayed as follows.
Page 113 Installing ACP Lonworks - When the program is run properly, the following screen is displayed.
Page 114: Input Indoor/Outdoor Unit And Ventilation Equipment Information
- When ACP Lonworks is connected to AC Manager, register information using AC Manager. - If ACP Lonworks is not connected to AC Manager, use LG ACCS program of the ACP Lonworks to register the information.
Page 115: When Acp Lonworks Is Not Connected To Ac Manager
When ACP Lonworks is not connected to AC Manager When ACP Lonworks is not connected to AC Manager, you can input the information of the indoor unit and ventilation equipment using LG ACCS (Advanced Centralized Control System) pro- gram of the ACP Lonworks.
Page 116 Installing ACP Lonworks - Click 'installation status' button. "Click" - Click 'automatic search' button. "Click" - When you click 'yes' button, the ACP Lonworks searches the address of the installed indoor units. "Click"...
Page 117 Installing ACP Lonworks <Screen during the search> <Screen after completing the search> NOTE Searching the installed indoor units • When you press 'yes', it searches the indoor units with the hexadecimal address of 00~FF and the ventilators with the hexadecimal address of 00~FF.
Page 118 Installing ACP Lonworks - Click ‘save’ button. "Click" Group setting When all of the information of the installed indoor units is displayed through automatic search, you need to set the groups. Group is the combining of the indoor units with the common attributes for convenient control. For example, you can make the groups of 1st grade and 2nd grade, or 1st floor and 2nd floor.
Page 119: Verifying And Checking The Acp Lonworks Installation
Check the connection of indoor unit air conditioner First, you need to check if the indoor unit air conditioner is connected by running LG ACCS of the ACP Lonworks. Check the ACP Lonworks status according to the following flowchart.
Page 120 ACP Lonworks status monitoring after executing lock all and temperature lock Run LG ACCS of the ACP Lonworks to select all indoor units, and execute lock all function. Afterwards, execute temperature lock function again, and monitor the status of the ACP Lonworks.
Page 121: Connecting With Lonworks Bms
Installing ACP Lonworks Connecting with Lonworks BMS After connecting with Lonworks BMS(Lonworks Building Management System), press Service Switch of ACP Lonworks. Then Service LED will be turned on and the Neuron ID will be sent to Lonworks BMS. Check that Service LED is changed to normal condition(LED OFF) within 10 minutes. If Service LED is change to normal condition, it is installed normally.

When GUI cannot be operated in LG ACCS, which is the operation program of the ACP Lonworks - When GUI cannot be operated in LG ACCS, which is the operation program of the ACP Lon- works, close Explorer window, and run new Explorer to access again.
Page 123 NOTES When the ventilation equipment is displayed as a network error state (code 242) in LG ACCS of the ACP Lonworks When the ventilation equipment is displayed as a network error state (code 242) as followed, in LG ACCS, which is the web server program of the ACP Lonworks, please check the following categories.
Page 124 NOTES It is installed by interfacing AC Ez and the ACP Lonworks, but some indoor units are not recognized, or not properly performing the central control commands. - It is the case of incorrect setting of AC Ez. Set all AC Ez to Slave mode. - If the indoor unit to control with AC Ez is in another physical line as in the following figure, the AC Ez cannot recognize the corresponding indoor unit.
Page 125 PI485 Main PCB Wrong connection When the image of LG ACCS is broken and you cannot see the screen such as the temperature well - Close LG ACCS, and rerun. ※Cautions - If PC is used for a long period of time, or several application programs are used at the same time, PC performance may be degraded and may affect the ACP Lonworks UI.
