RealTime Control Systems FDP2-BMS 9410-2-A6 Interface Installation and Operating Instructions

The FDP2-BMS 9410-2-A6 is a monitoring and control interface for Toshiba Digital Inverter, SHRM and SMMS range of air-conditioners. It provides the ability to control various unit operating parameters through resistance or voltage inputs, and reports faults by closing relay contacts. The FDP2-BMS can be used in single or multi-unit applications, and supports multiple configurations for different needs.

FDP2 Model 9410-2-A6
The FDP2-BMS Inputs S1 to S6 allow individual
control of various unit operating parameters. Each
input corresponds to a specific unit setting shown
in the table to the right. If an input is left
unconnected then the corresponding setting will
remain at a preset value.
S1 to S6 cables should be 0.5 to 1.0 mm2 multi-stranded screened twisted
pair. The screen should be earthed at one end only. The maximum
distance from the FDP2 to the input source is 200m.
The configuration switch SW1 changes the inputs S1 to S6 between
Resistance and Voltage modes.
Basic Cable Installation
Cabling should be a minimum 0.75mm2 throughout. Terminals TCC-NET
A/B connect to the Toshiba TCC-NET. 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.

FDP2 Description
RESISTANCE MODE
TCC-NET
A
D-BUS
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.
The FDP2-BMS is a monitoring and control interface for the Toshiba Digital
Inverter, SHRM and SMMS range of air-conditioners.
TCC-NET
Fault Reporting
To fault monitoring
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.
Control Functions
HARDWIRED CONTROL. Unit control can be achieved through resistance
inputs using potentiometer and volt-free contact inputs.

With SW1 ON inputs S1 to S6
operate in Voltage Mode. Voltage
ranges between 1V and 10V can
be used to modulate each input.
This mode is designed for
interfacing the FDP2-BMS to BMS
voltage outputs.
Each control input has a defined control range under voltage and
resistance mode as outlined in the following tables. Default settings are
applied if the input remains unconnected. These are indicated in the table
by the symbol .

It is recommended that volt-free contacts or switch mechanisms connected to S4, S5 and S6 have gold

ADDRESSING
The FDP2 has the facility to create control groups using multiple FDP2s
connected together on the D-Bus network. In standard configuration up
to 16 FDP2 devices can be connected together. Each FDP2 is assigned
a D-Bus address using the configuration switches SW4 to SW7. Unit
addresses are shown below.
Connecting additional FDP2-BMS or FDP2-F controllers as slaves allows
larger groups of units to be controlled from the master.
With no inputs connected the FDP2-BMS slave will duplicate the settings
of the FDP2 master. If one or more slave inputs S1 to S6 are connected
then each input on the slave will override the corresponding value sent
from the master. For example if S1 on a slave is connected, then the units
attached to the slave will be sent the local S1 setpoint rather than the
master setpoint. Similarly slave inputs S2 and S3 will override the
corresponding values from the master. 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.

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. Terminal D1 must be
connected to all other D1 terminals. Terminal D2 must be connected to
all other D2 terminals. 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.

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.
When operating in this mode, a 15 second delay will occur when
unlocking the keypad to allow the previous user settings to be restored.
Local Restore operation is shown in the following figure.

Frequently asked questions

The FDP2-BMS is connected to the Toshiba TCC-NET network using a minimum 0.75mm2 cable. Terminals TCC-NET A/B connect to the Toshiba TCC-NET, and terminals R1-R2 connect to fault monitoring equipment. The FDP2-BMS is powered by the TCC-NET and requires no extra power supply.

The FDP2-BMS operates in two modes: Resistance Mode and Voltage Mode. In Resistance mode, control is achieved using fixed or variable resistors. In Voltage Mode, control is achieved using voltage ranges between 1V and 10V.

The FDP2-BMS offers a number of standard configurations that can be set using switches SW1 to SW7. It can also be supplied in custom configurations to suit specific applications.
