The FTT-TLS daylight-based control device is used in a LonWorks network to control the
artificial light as a function of the available daylight in the room. The natural light can be
detected from a LUXMATE® light sensor connected directly to the FTT-TLS, or from a
light sensor in the network. Three groups of luminaires can be controlled continuously
between 0 and 100% output according to a separately programmable characteristic for
each luminaire group.

1 Applications

The FTT-TLS daylight control module is used in a LonWorks® network to control the artificial
light as a function of the available daylight in the room. To do this, the natural light is detected
either from a local LUXMATE® LSD light sensor connected to the FTT-TLS, or from LonWorks®-
compatible light sensors in the network.

Using the three independently addressable local DSI output channels, three groups of
luminaires (continuous rows) can be controlled continuously between 0 and 100% output
according to a characteristic separately programmable for each luminaire group. Each
luminaire group can contain up to 100 LUXMATE® lamp drivers, e.g. digital electronic ballasts,
phase and reverse phase dimmers as well as electronic transformers.

20 different lighting scenes can be saved in the FTT-TLS for each of the three DSI channels,
and these can be programmed and run via the LonWorks® network. Three of these 20 lighting
scenes are reserved for daylight-based lighting control. The lighting in the other scenes,
however, does not vary with changing daylight levels.

In addition to the three DSI output channels and the sensor input, the FTT-TLS also has inputs
for connecting momentary-action switches and presence detectors (resp. ordinary switches),
which can be used for:

   •   switching the lighting on/off

   •   dimming up/down

   •   enabling/disabling daylight-dependence of the 3 automated scenes.

Each of the three DSI channels can also use the signals from LonWorks®-compatible
occupancy sensors in the network to control scenes.

In addition, the FTT-TLS daylight-based control device can also provide daylight-based control
of luminaires that are not connected directly to the local DSI outputs, but connected to the
network via other nodes.

3.2       Installation instructions

      •    The mains supply is connected unswitched to the L and N terminals. The FTT-TLS must
           be fused for currents greater than 16A.

      •    If required, more than one switch can be connected in parallel. All connected inputs
           must have the same phase angle. The lower terminals of the On/Off, Man/Auto, T↑ and
           T↓ inputs are internally connected to the L terminal. The current through the internal
           connection must not exceed 1A.

      •    The DSI signal is transmitted by functional extra-low voltage (not safety extra-low
           voltage). You must therefore use installation material designed for 230V~ 50Hz mains
           voltage installation.

      •    The LSD light sensor is connected directly to the FTT-TLS daylight-based control
           device. The LSD must be mounted with a clear view towards the window (refer to
           mounting instructions).

      •    Check that the DSI outputs are wired correctly and operating properly using the
           integral test button and status LED.

3.3                      Wiring diagram for controlling luminaires connected directly to the device

In this case the FTT-TLS daylight-based control device controls the luminaires connected to
the DSI outputs directly.

Addressing and configuration is performed using standard LON tools - supported by the FTT-
TLS plug-ins - via the Service pin.

The control characteristics for the daylight-dependent scenes, plus the control settings for the
static scenes can be set either using standard LON tools, from scene control panels or directly
at the FTT-TLS using the programming keys; see chapter 4.

3.4      Wiring diagram for controlling luminaires via the network

The FTT-TLS daylight control module can also control luminaires that are not connected
directly to the local DSI outputs, but connected to the FTT bus line via other nodes, by
forwarding group control settings over the LonWorks network.

Another alternative is for an FTT-TLS to also provide the sensor values from its connected
LSD for use by other FTT-TLS modules on the network.

Addressing and configuration is performed using standard LON tools - supported by the FTT-
TLS plug-ins - via the Service pin.

The control characteristics for the daylight-dependent scenes, plus the control settings for the
static scenes can be set either using standard LON tools, from scene control panels or directly
at the FTT-TLS using the programming keys; see chapter 4.

3.5       Additional connection options


Buttons and switches with various functions can be connected directly to the FTT-TLS (not
compulsory). They always control all 3 continuous rows.

      •    Switch ON/OFF: The lighting can be switched on and off via the On/Off input. A level
           switch can also be connected instead of a timer switch or presence detector.

      •    AUTOMATIC/MANUAL operation: The Man/Auto input is used for switching off the
           daylight-dependent lighting adjustment in automated scenes.

           When switching to manual mode (switch closed) all channels are initially set to full light
           output1; then the settings can be changed using the T↑ and T↓ dimmer switches, and
           these levels retained even when the daylight level changes.

           On switching back to automatic mode, the lighting is adjusted to the computed control
           setting.

      •    Dimming UP/DOWN: The lighting can also be dimmed up/down as well as switched
           using the momentary-action switches connected to the T↑ and T↓ inputs. If two
           switches are connected, then T↑ raises the light level, T↓ dims it down. If just one
           switch is connected, and the two terminals are bridged with a wire, then the light level
           is dimmed alternately up and down with this switch.

           A short flick on the T↑ or T↓ switch switches the lighting ON/OFF - just like the on/off
           input2.




1
  Using the plug-in, the FTT-TLS can also be configured so that the currently set light level is maintained when
switching to manual mode.
2
  When switching on in manual mode, one can configure the module to switch to a fixed light setting , or to the light
level previously set before switching off (memory function).

4 Programming daylight-based control

The FTT-TLS daylight control module uses “characteristics” to control three luminaire groups
(continuous rows) in a room, where each row can have its own programmable characteristic.
The characteristic is specified by two system points.

The control characteristics for each of the 3 luminaire rows and each of the 3 automated
scenes are programmed either directly on the FTT-TLS or using standard LON tools -
supported by the FTT-TLS plug-ins.


4.1       Programming the automatic daylight control system directly on the FTT-TLS
      •    Make sure that the FTT-TLS is being addressed.
      •    Use a control unit to call an automated lighting scene.
      •    Open the switch connected to the Man/Auto input (if present).
      •    Open all devices that exclude the light from the room.
      •    Program the system points as follows:




FTT-TLS_HB 000921_en.doc                                                                     10
4.2       Setting the daytime system points
The settings are performed in the room with sufficient daylight, preferably when light row I -
closest to the window - is dimmed to the minimum level.
                                                                                    I       II      III                Day

The settings are made at twilight when the daylight no longer has any real influence. If
necessary the twilight system points can actually be programmed during the day with the
light sensor covered.

    Note: Each of the 3 characteristics can also be programmed separately. One can also start with twilight system
point programming. The previous system point is overwritten each time the programming button is pressed.

5 LonMark® objects and network variables

The individual LonMark® objects are described below on the basis of standard network
variable types, SNVTs for short, in the FTT-TLS.


5.1   The node object (object number 0)
The node object is used for communicating with the node and its objects, and issues error
messages.

It has the following structure:



                                                      FTT TLS
                                                (Node Object Type # 0)

                                                    Mandatory
                                 nviRequest                              nvoStatus
                           nv1   SNVT_obj_request    network       nv2   SNVT_obj_status
                                                    variables

                                 nviTimeSet                              nvoAlarm
                           nv3   SNVT_time_stamp                   nv4   SNVT_alarm

                                                    Optional
                                                    network
                                                    variables
                                                                         nvoFileDirectory
                                                                   nv8   SNVT_adress




The variables nviRequest, nvoStatus and nvoAlarm are used for communicating with the node
and its various objects. These variables enable error/status and alarm messages to be
received from every single object.

The node object itself only recognises one alarm status, the internal com_error.

nviTimeSet is used for recording the time from LonWorks-compatible clocks. If an alarm
message occurs, it is recorded with the current time in SNVT_Alarm, so that each alarm
message contains the time the alarm occurred as well as its priority.




FTT-TLS_HB 000921_en.doc                                                                    12
5.2   The scene controller objects (objects 1 to 3)
There is a scene controller object for each DSI output channel, i.e. three for the node. These
objects are based on the "Scene controller" function profile of the LonMark standard.

A few network variables have been added, however, to increase functionality:

                                                      Scene Controller DSI X
                                                        (Object Type 3251)


                                                         Mandatory
                                  nviScene_0X                                  nvoOutput_0X
                            nv1   SNVT_scene              network        nv2   SNVT_switch
                                                         variables


                                   nviSetting_0X
                            nv3    SNVT_Setting

                                                           Optional
                            nv4
                                   nviDirect_0X            network       nv6
                                                                                nvoScenFb_0X
                                   SNVT_switch                                  SNVT_scene_config
                                                           variables

                                   nviScenCf_0X
                            nv5    SNVT_scene_config




                                   nviLightLevel_0X
                                   SNVT_lux



                                   nviOccupied_0X

                                                      nc95 - nciFadeTime_0X
                                                      nc96 - nciDelayTime_0X




_0X stands for 01, 02 or 03 for the corresponding controller number.

nviScene_0X is used for controlling the light scenes, each controller managing 20 different
scenes. Actual light scenes can also be learnt, and characteristic points programmed in
automatic mode.

The configuration variables shown in the lower section of the diagram are used when learning
light scenes for programming a fade time and a delay time for the light scene.

A master fade function is implemented with nviSetting_0X. Apart from On and Off, which are
used as rapid control commands for running the last scene or switching off the DSI output, the
light level can also be set as a percentage of the control setting at that moment with a
resolution of 0.5%. The fade time is implemented by the controller itself.

nviDirect_0X is used for direct adjustment of the controller using e.g. LonWorks-based
momentary action switches and rotary regulators. Here it is also possible to use a plug-in to
set the run time for the adjustment process.

The variable pair nviScenCf_0X and nvoScenFb_0X enable programming of light scenes by all
sorts of network management tools. Scenes can be programmed using nviScenCf_0X, or the
current setting for scenes displayed using nvoScenFb_0X.



FTT-TLS_HB 000921_en.doc                                                                            13
The reading from a LonWorks-compatible light sensor can be recorded in the nviLightLevel_0X
variable for each object to provide daylight correction over the network. This reading is
monitored on each controller for time-out, to prevent malfunctioning of the daylight
correction process if sensor signals fail to appear.

The nviOccupied_0X variable is used for each object for recording a LonWorks-based presence
detector signal in order to control the switch-on and switch-off scenes according to room
occupancy.

The DSI output value is constantly available on the network via the output variable
nvoOutput_0X. This can be used in visualisation systems for displaying the current value, or
for proportional control of other LonWorks actuators in sync with a DSI output.

This comprehensive range of parameters is configured using a plug-in for each controller.

Each controller can generate the following error messages for the node object (in the
variables nvoStatus and nvoAlarm): "Short circuit on DSI line", "Break on on DSI line" and

5.3   The DSI group controller (object 4)
Using the DSI group controller, light scenes from individual DSI controllers or all DSI
controllers can be run simultaneously using discrete switch sensors.

The group controller has the following structure:



                                                DSI GroupContr
                                                (Object Type #5)



                               nviScenCall_01                      nvoScenActive_01
                               SNVT_switch                         SNVT_switch

                               nviScenCall_02      Sender          nvoScenActive_02
                               SNVT_switch         section         SNVT_switch

                               nviScenCall_03                      nvoScenActive_03
                               SNVT_switch                         SNVT_switch

                               nviScenCall_04                      nvoScenActive_04
                               SNVT_switch                         SNVT_switch

                               nviScenCall_05                      nvoScenActive_05
                               SNVT_switch                         SNVT_switch




Each of the groups are controlled by the 5 network variables nviScenCall_01 ... _05 (format
SNVT_switch), with the associated group output variable nvoScenActive_01 ... _05 indicating




FTT-TLS_HB 000921_en.doc                                                                14
the last group enabled. This can be used to display the status conditions on a switch indicator
panel for instance.

The group parameters are also set using a plug-in.



5.4     The light sensor object (object 5)
The light sensor object is used for indicating the locally connected light sensor reading in the
LonWorks network. This means that other actuators and controllers throughout the network
can use this illuminance reading.

The sensor resolution can be set using a plug-in, allowing a range of different sensors to be
used.

The light sensor object has the following structure:



                                        LightSensor
                                    (Objekt Type # 1010)

                                                            nvoLSI_Value
                                                      nv1   SNVT_lux




It has a single network variable, nvoLSI_Value, with a value ranging from 0 to 65,535 Lux,
resolution: 1 Lux.

The light sensor object generates the following error messages in the node object (in the
variables nvoStatus and nvoAlarm): "short circuit" and "open circuit" in the sensor channel.

5.5         Generic actuators (objects 6 to 9)
Normally the FTT-TLS is operated using switches connected locally to the device. Using
generic actuators, however, it is also possible to control functions over the network.

The generic actuators have the following structure:

                           ActDimDown                                       ActDimUp                                        ActManAuto                                     ActOnOff
                         (Objekt Type # 3)                               (Objekt Type # 3)                                (Objekt Type # 3)                            (Objekt Type # 3)

       nviTasterDunkel                                   nviTasterHell                                  nviSwManAuto                                    nviSwEinAus
 nv1   SNVT_switch                                 nv1   SNVT_switch                              nv1   SNVT_switch                             nv1     SNVT_switch




The dim up/dim down functions are accessible simultaneously both from local momentary-
action switches and via the network, whereas the switch signals reach the device either locally
or over the network. In the latter case it is the plug-in that sets the parameter defining the
origin of these signals.


5.6         Switch objects (objects 10 to 13)
4 switch objects of type "Functional Profile Switch" are used to provide the positions of the
local switches to the network, so that other actuators or controllers in the network can be
controlled by these switches.

Their individual structures are shown below:

       SwDimDown                                          SwDimUp                                      SwManAuto                                            SwOnOff
   (Objekt Type # 3200)                              (Objekt Type # 3200)                          (Objekt Type # 3200)                               (Objekt Type # 3200)

                                 nvoTasterDunkel                                  nvoTasterHell                                  nvoSwManAuto                                      nvoSwEinAus
                           nv1   SNVT_switch                                nv1   SNVT_switch                             nv1    SNVT_switch                                 nv1   SNVT_switch




FTT-TLS_HB 000921_en.doc                                                                                                                                                                   16
6 Parameters and plug-ins
The FTT-TLS has numerous parameters that can be conveniently configured from the LNS
network management tool with the aid of graphical user interfaces (plug-ins).

There are six plug-ins in total for the FTT-TLS:

   •   a general plug-in with all basic parameters for DSI channels, momentary-actions
       switches, ordinary switches and the DSI group controller,

   •   a plug-in for each of the 3 DSI controllers for configuring and setting parameters for
       light scenes, daylight characteristics, run times, start-up characteristics etc., and also
       for monitoring the DSI control settings and assigned light sensor value for the DSI
       channel.

   •   a plug-in for the light sensors (internal and external) for setting the resolution and
       time-out parameters

   •   a plug-in for the momentary-action switches and ordinary switches for setting the
       parameters for presence detector operation and run times.

Most of the parameters influence how the FTT-TLS controller works, and any change in
parameters is downloaded over the LonWorks network to the FTT-TLS.
