JMT (Joint Matching Test)

This is necessary for every independent BMS.

The case where a JMT is not necessary is where previously a successful JMT has been carried out and the BMS system has not been updated by software or hardware changes. In the case that the

BMS has updated their system by either changes, a following JMT will be required.

ACP BACnet Diagnosis

Use of LG’s ACP BACnet setup-tool is for confirming the operation/state of connected A/C units & address ID’s, prior to connection with the BMS system.

BMS Engineering

Creating of the Points. This is NOT to be done by LG since it is directly related to the BMS side. The

BMS engineer is to carry out the engineering of the Point, however LG is responsible for providing the method of how the Points are calculated.

Commission

First step, only using LG’s ACP BACnet, without connecting BMS. This is to be carried out by LG engineering staff with the use of the ACP BACnet set up tool.

Discrepancy of operation of Gateway by BMS

In the case that the BMS maker feels that the ACP BACnet is not functioning correctly via the BACnet

Protocol, a test with the use of LG’s ACP BACnet Client software can confirm this. (This test is generally not required)

Initialization at the Start Up

The system is designed to automatically recognize the connected air conditioners. Therefore, a period of approximately one minute will be required to recognize all the air conditioners after the system is turn on. During this period, the following error PDU may be returned when an object corresponding to an air conditioner is accessed.

ErrorClass = Object; ErrorCode = Unknown_Object

If an attempt is made to read the Object List property of the Device object from an air conditioner during the above period of recognition, the following error PDU will be returned, unless the air conditioner has been recognize:

ErrorClass = Device; ErrorCode = Configuration_In_Progress

Communication error response of ACP BACnet, please refer to refer to ACP-BACnet Error

Response Table on page 95.

Clock Setting

The Timesynchronization service allows clock settings by the local time.

Furthermore, the UTCTimesycchronization allows clock settings by UTC


Report Function

Event Notification

1) Registration of Event Notification Destination

It is possible to use the AddListElement service to register notification destination information on the Recipient List property of the Notification Class object.

2) Deletion of Event Notification Destination

The RemoveListElement service can be used to delete notification destination information from the Notification Class object.

3) Event Notification Destination in Memory

The registered event notification destination is stored in the memory. When the system is turned on, the event notification destination will be initialized with the stored information. The Event notification destination will be stored five seconds after the registration or deletion.

COV(Change of Value) Notification

A request for COV registration is accepted through the SubscribeCOV service.

1) Setting of Confirmed or Unconfirmed COV

This item is supported according to the BACnet Specifications.

2) Setting of the desired lifetime of the subscription

This item is supported according to the BACnet Specifications.

When COV notification is made at the time of status change, the difference between the registered time and present time will be calculated. If the difference is greater than the registered lifetime of the subscription, the subscription will be judged expired and deleted. Therefore, if a clock time change is made, the lifetime of the subscription may differ from the value that has been set.

3) Memory after Interruption of Power Supply to System

This item is not supported. Registration information is not stored in the memory, and will be lost when the power is turned off. According to the BACnet Specifications, It is not required to guarantee preservation of subscriptions across power failure.

NOTES 81

NOTES

Troubleshooting

During the use of the ACP BACnet, if unexpected problem occurs, please find the solution by studying the following list. If there is no solution, please access www.lgservice.co.kr to report the problem.

When Tx or Rx LED of CH1~4 port is not blinking during the product installation

When Tx or Rx LED of CH1~4 port is not blinking during the product installation, run it after setting the indoor and outdoor unit groups.

When GUI cannot be operated in Web GUI, which is the operation program of the ACP BACnet

1. When GUI cannot be operated in Web GUI, which is the operation program of the ACP BACnet, close Explorer window, and run new Explorer to access again.

2. Close all iexplorer.exe process in Task Manager, and access to the ACP BACnet again.

• After running Task Manager, you can select ‘Task Manager’ in the popup menu window displayed by clicking the right button of the mouse on the menu bar of the window.

82 NOTES

When the ventilation equipment is displayed as a network error state (code 242) in LG

Web GUI of the ACP BACnet

When the ventilation equipment is displayed as a network error state (code 242) as followed, in Web

GUI, which is the web server program of the ACP BACnet, please check the following categories.

• Check if the BUS-A and BUS-B of RS-485 cable are incorrectly connected.

• Check if there is a communication defect between the remote controller and the indoor unit.

• Check if the PI485 DIP switch is incorrectly set.

• Check if the indoor unit address for the central control is not set.

The CH242 (network error) keeps occurring and disappearing in the ACP BACnet controller.

Case of incorrect connection of RS-485 communication line

If each communication line is connected altogether as in the following figure, the communication line must be separated.

PI485 PI485 PI485 PI485

LON N/A SVC

ACP BACnet

Duplicate setting of the indoor unit address

It is the case of two or more indoor units are set with the same address. It may be the case of several indoor units having the default address 00 by not setting the central control address from the beginning for some indoor units.

In such case, assign unique address to each indoor unit not to have indoor unit with a duplicate address.

NOTES 83

It is installed by interfacing 16 room central controller and the ACP BACnet, but some indoor units are not recognized, or not properly performing the central control commands

• It is the case of incorrect setting of the simple central controller (16 room central controller)

DIP switch.

Set all simple central controllers to Slave mode, and reset the power.

• If the indoor unit to control with simple central controller is in another physical line as in the following figure, the simple central controller cannot recognize the corresponding indoor unit.

Therefore, the connections need to be modified to have the simple central controller to be in the same RS-485 communication line with the indoor unit to control.
