LONWORKS GATEWAY

No. 6 and No. 7,8 are all for power supply. Therefore, only one of two combinations should be used. When DC 12V is used for the power, Connect No. 6 to the power (not necessary to use No. 7,8.) When DC 12V is NOT used for the power, Connect No. 7, 8 to the power (not necessary to use No. 6.)

Installation order

Installation Manual 11

ENGLISH

Installation order

1. Install the product according to the setting of the central controller address of the indoor unit and the DIP S/W of PI485. (Set the DIP switch No. 4 to ON.) (Refer to the PI485 installation manual for details.)

2. Connect BUS_A and BUS_B (485 communication line) while paying attention to the connecting polarity. (Refer to the next page.)

3. LON (TP/FT-10 line‡Lonworks Gateway communication line connection) TP/FT-10 communication line does not have polarity. Connect the 2 communication lines to BMS.

4. PWR (Power supply) You can select either one of the two for the power supply.

Use DC 12V power adapter Connect to No. 6 in name of each part.

When separate DC12 can be supplied Connect 12V and GND to No. 7 and 8 terminals.

5. When you press the service switch after connecting to the Lonworks system, the service LED is turned on and the neuron ID is automatically transmitted to the Lonworks system.

6. Check whether the service LED is in normal condition (OFF condition) within 10 minutes. If the service LED is in normal condition, the installation has been done normally.

7. When using the fire detection port, connect the two terminals of the fire diction sensor to F1 and F2. (Fire detection sensor must be used for DC output of 12V or below.)

8. After the installation, connect the LAN cable between the PCs to use the web server so that you can check whether the LG product has been installed normally. – Refer to the remote diagnosis function part (page 16) for details.

When connecting the signal line to the terminal of Lonworks Gateway, always use a manual driver. (Careful attention is required not to damage the terminal block and PCB.)

[Wiring sequence]

1. Connect 485 communication line

- Pay attention to BUS A and BUS B polarity (Refer to the G/W manual for DIP S/W information for 485 G/W.)

2. Connect the Lonworks communication line (TP/FT-10)

- No polarity.

3. Power supply (Select one from No. 1 or 2)

Use DC 12V adapter

- Connect to No. 6 jack from name of each part.

Supply DC 12V to installation site

- Connect 12V and GND to No. 7 and 8 terminals.

4. Interface with simple central controller

- Set the DIP S/W No. 2 of the simple central controller to ON and configure the setting according to the rotary S/W address. (Refer to setting part when connection to simple central controller (page 20) for details.)

5. Connect fire detection sensor

- When the signal of DC 12 or below is transmitted in case of a fire, the indoor unit and ventilation product that is connected to BNU-LW will all be turned off.
