User manual TOSHIBA RBC-SH-A1LE2

[. . . ] TCC-NET installation should follow Toshiba installation specifications. Terminals R1-R2 connect to fault monitoring or indication equipment according to the specified rating of the relay. The FDP2 is powered from the TCC-NET and requires no extra power supply.

TCC-NET RESISTANCE MODE TCC-NET D-BUS RELAY VOLTAGE MODE A B D1 D2 C R1 R2 Fault Reporting The FDP2-BMS Interface detects all indoor and outdoor faults occurring in TCC-NET compatible Toshiba air-conditioners and reports them by closing relay contacts R1-R2. [. . . ] The FDP2-BMS is connected on the TCC-NET network with or without a standard remote controller and detects any faults that can be displayed on the controller for up to 8 units. Red and Green LEDs Indicate Fault/No Fault state. A B To fault monitoring With SW1 OFF the inputs S1 to S6 operate in Resistance Mode, unit operation can be controlled by connecting fixed or variable resistors to inputs S1 to S3 and latching switch inputs to inputs S4 to S6. With SW1 ON inputs S1 to S6 operate in Voltage Mode. This mode is designed for interfacing the FDP2-BMS to BMS voltage outputs. Toshiba Remote Controller Control Functions HARDWIRED CONTROL. Unit control can be achieved through resistance inputs using potentiometer and volt-free contact inputs. Unit control can be achieved through 1-10V voltage inputs integrated with BMS control outputs. Multiple FDP2 Interfaces can be connected to form large groups of units. FDP2 interfaces can be supplied in custom configurations to suit specific applications. If an ON signal is applied to inputs S4 to S6 then this will override an OFF value sent from the master. The example below shows a setpoint override on a slave. S1=25oC From MASTER 18 8 Units max ADDRESS 1 ADDRESS 5 ADDRESS 9 ADDRESS 13 18 25 ADDRESS 2 ADDRESS 6 ADDRESS 10 ADDRESS 14 Address 0 (MASTER) 18 ADDRESS 3 ADDRESS 7 ADDRESS 11 ADDRESS 15 18 Address 0 is the FDP2 MASTER address. Address 1 to 15 are FDP2 SLAVE addresses that can be used to create large control groups. NETWORK INSTALLATION The D-Bus network requires a twisted pair cable connecting terminals D1 and D2 on each FDP2 as shown below. In addition the common terminal C on all devices must be connected together. If a shielded cable is used then the shield can be used for this purpose. The network must be installed as a point to point BUS configuration, Star and Ring connections must NOT be used. 8 Units max D-BUS Address 1-15 (SLAVE) Local Restore Mode SW3 D-BUS 16 FDP2 max Address 1-15 (SLAVE) With S6 closed (UNLOCKED) the remote controller on the master FDP2 is unlocked and all slaves operate to the master remote controller settings. S6 8 Units max SW3 enables Local Restore Mode on master and slave FDP2-BMS. [. . . ] The network must be installed as a point to point BUS configuration, Star and Ring connections must NOT be used. 8 Units max D-BUS Address 1-15 (SLAVE) Local Restore Mode SW3 D-BUS 16 FDP2 max Address 1-15 (SLAVE) With S6 closed (UNLOCKED) the remote controller on the master FDP2 is unlocked and all slaves operate to the master remote controller settings. S6 8 Units max SW3 enables Local Restore Mode on master and slave FDP2-BMS. In this mode the remote controller settings are saved when the FDP2 enters central/locked operation. When the remote USER RESTORE controller returns to local operation the saved settings are restored to the remote controller. [. . . ]
