User manual TOSHIBA BMS-IFLSV3E INSTALLATION MANUAL

[. . . ] · After the installation work, perform a trial operation to check for any problem. Explain how to use and maintain the unit to the customer. Ask the customer to keep this Installation Manual. WARNING · Ask an authorized dealer or qualified installation professional to install or reinstall the TCB-IFMB640TLE. [. . . ] If connected with incorrect polarity, the unit will not work. · The TCC-LINK signal lines have no polarity. Power cables/Earth wires/Signal wires Connect power cables, earth wires, and signal wires to the specified terminals on the terminal block. Connect the shield wire of the TCC-LINK communication wire to the earth on the air conditioner side. Do not connect the shield wire to the terminal block. Connect the shield wire of the RS-485 communication wire to the earth on the host system side. Do not connect the shield wire to the terminal block. It should be open and insulated. Secure each cable with a cable clamp.

Length of stripped power cable Length of stripped RS-485 communication wire REQUIREMENT Disconnect the appliance from the main power supply. This appliance must be connected to the main power supply by a circuit breaker or switch with a contact separation of at least 3mm. Fasten the screws to the terminal with torque of 0. 5Nm. 6 (EN) SW1 SW2 SW3 SW4 1 2 3 4 ON L N TCS-NET Relay Interface Installation Manual Wiring Connection The following describes a connection example when using two or more TCS-NET Relay Interface units. Terminator resistor setting (See "6 Setting" for the setting method. ) · Set the RS-485 terminator resistor to "Resistor set (120 ohm)" for No. 1 (relay interface address SW1=1) TCSNET Relay Interface unit, and set to "open" for other units. · Set the TCC-LINK terminator resistor to "open" as it is set on the air conditioner side. Shield earthing · The shield of RS-485 signal wires should be connected at closed end, and the terminal end should be open and insulated. The shield earth of the RS-485 signal wires should be single-point earth at the host system. The shield earth of the RS-485 signal wires should be single-point earth. · The shield of TCC-LINK signal lines should be connected at the closed end, and the TCS-NET Relay Interface terminal end should be open and insulated. Earth is connected on the air conditioner side. TOUCH SCREEN CONTROLLER INTELLIGENT SERVER TCC-LINK U1 and U2 have no polarity. The shield of TCC-LINK cable should be open and insulated. It is not connected to the terminal block. TCC-LINK terminator resistor is set on the air conditioner side. [. . . ] Set these switches to zero (0) or "all OFF". RS-485 terminator resistor select switch Set "Resistor set (120 ohm)" only when the relay interface address SW=1, and set "open" for other relay interfaces. SW1 SW4 TCC-LINK terminator resistor select switch The TCC-LINK terminator resistor is set on the air conditioner side. Reset switch When performing an address setting with SW1, push this reset switch after the address setting to read the set value. Relay interface address set switch 1-8 0, 9-F Relay interface address Not used TCC-LINK U1 FG 2 ON LED5 SW6 LED4 ON 1 SW3 SW2 SW3 SW4 SW5 Test switch (0 usually) Test switch (all OFF usually) Test switch RS-485 terminator resistor select switch ON ON U2 LED3 1 2 4 3 RS-485 B A SW7 LED2 LED1 SW1 SW2 ON SW5 1 2 3 4 1 2 3 4 1 2 3 4 Resistor Set SW6 Open Bit1: pull-up resistor select.
