1. TRIOS SYSTEM INTRODUCTION
The Trios Concept
Trios is a multi-functional, stand-alone lighting control system that meets today’s demand for
energy efficient, flexible and user-friendly lighting solutions. When the light controller is combined
with the Philips range of sensors, potentiometer and/or standard push-button switches, Trios
becomes a versatile control system for indoor applications such as offices, schools, sports halls
and industrial sites.
A Trios system is easy to install, it does not require any complex adjustments and it can be used
to control any type of dimmable and non-dimmable lighting load. Philips sensors are simply
snapped into the light controller using telejack cables with modular plugs while its built-in
intelligence ensures that the correct lighting functions are obtained at all times.
Trios Multi-functionality
The most essential aspect of Trios lies in its multi-functionality. Energy savings of up to 70% are
possible when lights are controlled automatically by a light sensor and movement detector.
Infrared remote control can be added to enhance user-comfort by offering full light control from
anywhere in an office. Potentiometers and push-button switches can be used if conventional light
control is preferred.
Trios Flexibility
Individual Trios light controllers can be addressed by infrared remote control so that the lighting
installation in modular and open-plan offices can be easily adapted when partition walls are
relocated. This enhances the flexible use of office areas without the need for electrical re-wiring
when layouts change. Since the need for vertical switching wires to wall switches is eliminated,
the initial electrical installation costs are significantly reduced.
Trios Simplicity
of Installation Installing the Trios system does not require much time or expert knowledge.
Sensors are simply snapped into the light controller’s input socket using standard telejack cables
and plugs. Extension cables with telejack plugs and sockets are available to increase existing
cable lengths. Branching connectors are used to add more sensors to Trios. Commissioning
efforts are minimal because Trios can automatically identify the connected peripheral
configuration and choose the correct lighting functionality for that configuration.
Trios functionality
The Trios lighting control system includes a variety of functionality’s.
Manual control
Infrared Remote control. Lights can be switched and regulated with any number of hand-held or
wall-mounted transmitters. Up to four different lighting scenes can be stored with the hand-held
transmitter and recalled with the hand-held and wall transmitter.
Conventional light control.
Light switching (toggle on/off) with any number of push-button switches and dimming with an
electronic potentiometer.
TRIOS

Multi-functional push-button control.
Switching, dimming and presets for lighting scenes using standard push-button switches
connected to Trios via the push-button interface.
Manual control with Energy saving
Movement detector with infrared remote control. IR is used to recall stored lighting scenes and to
switch and regulate individual luminaire groups. The movement detector ensures that the lights
are automatically switched off when areas are unoccupied for longer than the defined delay time.
Lights are not automatically switched on when areas are re-occupied.
Light sensor combined with infrared remote control
IR is used to set reference levels for ‘constant lux’ and ‘daylight linking’ applications without
having to adjust the sensitivity of the light sensor. Lights are automatically regulated to maintain
the selected lux level when daylight levels change and are automatically switched off when
measured lux levels are too high. Lights are not switched on automatically when daylight levels
drop below the defined reference level.
Light sensor and movement detector with IR remote control.
Lights are automatically regulated to maintain the IR remote control selected lux level and
switched on or off when measured lux levels are too low or too high respectively. Lights
automatically switch off when areas are unoccupied but cannot automatically switch on when reoccupied, i.e lights have to be switched on by IR remote control
“Hands-free” control with Energy saving
Light sensor and movement detector with potentiometer. The potentiometer is used to set the
reference level for the light sensor. Lights are automatically switched and regulated to maintain
the selected lux level. The movement detector automatically switches lights off when an area is
unoccupied, and on when it is re-occupied.

2. TRIOS SYSTEM OVERVIEW
The range of multi-functional light controllers, sensors and potentiometers from Philips, the pushbutton switches from e.g. Busch & Jaeger and Merten, the special sensor cables and extension
cables, interlink cables and branching connectors from Philips or other suppliers are the
components that can be found in a Trios lighting control system.
Sensors, push-button switches and potentiometer are connected to the light controller to obtain
the desired lighting functionality. Sensor cables terminated with modular plugs at both ends and
extension cables with modular plugs and sockets are used to bridge the distance between the
sensor and light controller. Interlink cables terminated with modular plugs at both ends are used
to link various Trios light controllers, and branching connectors are used when more sensors
have to be connected to the light controller.
All the Trios light controllers are designed to switch inductive, capacitive and resistive lighting
loads upto 5A. The dimmable versions can regulate up to 150 luminaires simultaneously if they
are fitted with Philips HF-Regulating ballasts for fluorescent lamps. Incandescent lamps, high-volt
halogen lamps and low-volt halogen lamps can be regulated via the 100 VA electronic dimmers of
Philips or via other suitable dimmers with a 1-10Vdc control voltage interface.

Trios is an intelligent, multi-functional light controller that translates peripheral inputs into light
switching and regulating commands via a functional control program.
Light controllers are available in three functional versions; a non-dimmable (LRC1010 and
LRC1015) and dimmable version (LRC1020 and LRC1025) with fixed lighting functions for
standard solutions, and a dimmable version with programmable functions for tailor-made
solutions (LRC1030 and LRC1035). As an additional feature, the LRC1030/1035 has two control
outputs for the individual dimming of window side luminaries and corridor side luminaries in a
room. The programmable control functions are defined by a personal computer through menu
controlled programming software (the programming manual for the programmable light controller
version is included in Appendix A).
installations
Housing
To take account of the various installation practices, all three functional versions are available in
an installer box housing for screw mounting against a ceiling or wall and in a DIN-rail housing for
standard 35mm DIN rail mounting in mains distribution cabinets or similar.
The installer box version has been designed for various types of cable gland options. Its front
panel has four, 19mm wide slots with removable gates: 2 gates with open access holes for mains
connections and 2 with “knock-outs” for the control voltage connections. The access holes are
primarily dimensioned for standard PG 13.5 cable glands but the gates can also be removed for
other cable access solutions (e.g. HAF 3525 gates with pull-relief or HAF 3529 gates for 19mm
diameter pipes).

Connecting peripherals
The number of peripherals connected to a Trios light controller is limited to one potentiometer,
one light sensor, three movement detectors, three IR receivers and three push-button interfaces
for multi-functional push-buttons. Any combination is possible as long as the given maximum
numbers are not exceeded. The number of push-button switches connected to one light controller
is unlimited. Three-fold branching connectors (LCC8024) must be used when more than one
sensor is connected to a light controller.
The sensor cables can be extended by using one or more extension cables, which are available
in 5m (LCC8012) and 20m lengths (LCC8013). Extension cables have modular plugs and sockets
to simplify connections.
The maximum distance between a light sensor and a light controller is 125 meter
The maximum distance between a movement detector and a light controller is 125 meter.
The maximum distance between a IR receiver and a light controller is 30 meter
The sum of all sensor cabling must be less than 125m.
The maximum allowable potentiometer cable length is 30m
The maximum allowable cable length from a push-button to a controller is 125m.
The figure shows how peripherals can be connected to a single light controller.
Remark:
The maximum cable length’s in the drawing are different comparing to the text, the info in the text

3. Interlinked Trios light controllers
Infrared receivers, movement detectors and a light sensor can be connected to a group of linked
light controllers to allow for the use of lighting scenes, or simply to increase the controlled lighting
load. As shown in the diagram (fig2.4 a), each light controller is connected to the mains power
supply, switches and regulates its own lighting load and receives the same sensor signals via the
interlink cables.
Up to five Trios lighting controllers can be linked together via their sensor input sockets with 1m
long, LCC8011 interlink cables and LCC8024 3-fold branching connectors. If interlink cables
lengths are insufficient, sensor cable LCC8014 or extension cables can be used to increase the
distance between the light controllers. Sensors can be connected to any available input socket
within the group.
The number of infrared receivers, movement detectors and light sensors that may be connected
to a group of interlinked light controllers, is the same as for a single light controller. This also
applies to the distance between the sensors and light controller. If more than two light controllers
are interlinked, the allowable sum of cable lengths is reduced from 125m to 100m or 85m.
Up to 50 light controllers (fig.2.4 b) can be connected to (no more than) one potentiometer so that
large numbers of luminaries can be regulated simultaneously. Any number of light controllers can
be connected to one or more push-button switches. A typical application could be conventional
light control with multiple switch points in large industrial halls. The maximum cable length
between a light controller and push-button switch or potentiometer may not be more than 125 m
or 30 m respectively.

Master/slave configurations
If many luminaires have to be controlled by for example, infrared remote control and/or light
sensor, the regulating output of the ‘master’ light controller can be connected in parallel to the
potentiometer inputs of up to 25 ‘slave’ controllers. The ‘slave’ controllers (dimmable versions
only) pass the received control voltage directly to the regulating inputs of the ballasts. The ‘slave’
controllers act as amplifiers to increase the number of simultaneously regulated luminaries. Since
each ‘slave’ controller can regulate up to 150 Philips HF ballasts (ETC/R or HFR range), a single
‘master’ controller is therefore able to control a maximum of 3750 ballasts simultaneously. A
typical application could be daylight regulation in large, glass-roofed livestock enclosures (e.g.
chicken farms) containing a very large number of dimmable luminaries.
A Trios ‘master’/’slave’ configuration is only useful if the number of luminaires that have to be
controlled simultaneously is larger than the maximum number of luminaires that can be controlled
in a group of linked light controllers
As shown in the diagram the ‘slave’ controllers are switched by an external mains contactor. The
lights connected to the ‘slave’ controllers can only switch on after a power interruption if the
embedded application software in each ‘slave’ controller detects movement. Since movement
detectors are not connected, an active movement detector signal must be simulated by other
means. This can be done by short circuiting the movement detector pins of a telejack plug and
connecting this plug to each slave controller’s sensor input socket. The short circuit can be
realised by interconnecting pins 2 and 6 of a telejack plug with an electrical wire. The external
mains contactor can be switched by the ‘master’ light controller or by other means.
The type of peripherals connected to the ‘master’ controller determines the obtained lighting
functionality. The number and type of peripherals connected to the ‘master’ controller and the
allowable cable lengths, are the same as for a single light controller
TRIOS

Switching lighting loads via external mains contactors
Trios employs an ingenious switching method using a triac circuit in combination with a relay
contact to ensure that any type of lighting load can be switched up to 5A without generating
sparks or inrush-currents.
In some applications, e.g. sports halls and industrial complexes, Trios must switch large lighting
loads (> 5A) via high inductive external mains
Contactors.
Contactors can cause problems in Trios’ switching circuit when they have to be opened to switch
lights off (closing the contactor is never a problem). When inductive loads (cos phi « 0.5) are
switched off, Trios’ switching circuit re-triggers the triac and prevents the external contactor from
opening.
The problem can be alleviated by either placing a small resistive load parallel to the external
contactor (e.g. small lamp) or by simply adding a transient suppresser (i.e. a RC-unit or ‘sparksuppresser’) over the switched output of Trios as shown in the diagram
A suitable transient suppresser for most external contactors is one with a capacitor value of: C =
0.25µF and a resistor value range of: R = 22-470 Ohm.
Other types of transient suppressers can also be used but your choice depends on the
contactor’s specified coil consumption. If the contactor’s coil consumption( needed to close the
contactor) is higher than 50VA, a transient suppresser with a capacitor value of C = 0.1µF is
sufficient, otherwise a higher capacitor is needed (e.g. 0.25µF). The resistor value must be larger
or equal to 22 Ohm.
Regulating lighting loads
Dimmable Trios light controllers have a separate 1 - 10 V dc control interface to regulate the
output level of a lighting load. Because lamps cannot be regulated directly, they have to be
connected to Trios regulating output via dimmable ballasts or dimmers with a 1 - 10 V dc control
interface. Philips regulating ballasts and dimmers have a standardised dim-curve which relates
the light output level to the control voltage between 1 and 10 V dc (lighting levels increase with
increasing control voltages). Trios control voltage may produce different lighting levels when
dimmers and ballasts from other suppliers are used.
Control interfaces have two polarity sensitive terminals (plus and minus) that are either current
sinking (light controllers) or current sourcing (HF ballast and dimmers). Current sinking interfaces
absorb the current generated by one or more current sourcing interfaces. The number of ballasts
and/or dimmers that can be regulated simultaneously by a single dimmable light controller
therefore depends on the specified current sourcing of each connected ballast or dimmer.
TRIOS
training-manual 1. 2
11
Because Philips HF ballasts (ETC/R and HFR range) and dimmers (LRD8000 and 8010) source
0.15 mA and 0.5 mA respectively, a maximum of 160 ballasts or 50 dimmers can be regulated
simultaneously by a Trios dimmable light controller, which sinks up to 25 mA. The programmable
light controllers (LRC1030/1035) have two regulating outputs that can sink up to 20 mA each.
Trios light controllers and Philips dimmers have a double (4kV) isolation barrier between their
control interface and main parts. Philips HF regulating ballasts have a basic (2kV) barrier. This
means that signal wire cables can be used to connect the control interfaces of Philips dimmers to
the regulating output of Trios. For the connection of HF regulating ballasts to the regulating output
of a Trios light controller, mains type of wiring must be used. In order to avoid interference,
control cables must not be placed in the same cable duct compartment as the mains cables.

4. Daylight linking
Daylight linking can be divided into two principles:
G
G
Daylight switching
Daylight regulating
Daylight switching (LRC1010/1015)
Production halls and large warehouses often have windows on the roof to increase the
contribution of daylight in working areas. The amount of natural light during the day is usually
sufficient for some luminaires to remain off. In these applications, a light sensor and nondimmable Trios light controllers (LRC1010 or LRC1015) are ideal to automatically switch selected
luminaires off when measured ambient lux levels are sufficiently high or on when they are too
low.
Luminaires in daylight switching application have non-dimmable HF ballasts and cannot maintain
a constant lux level. As a result, lux levels change abruptly when Trios automatically switches the
lights on and off. The daylight level at which Trios automatically switches lights on is defined by
the reference level in Trios and by the sensitivity of the connected light sensor. Since the
reference levels are fixed in non-dimmable light controllers, the only way to change the lux level
at which Trios automatically switches lights on, is to change the factory adjusted sensitivity of the
light sensor. As with daylight regulation, automatic switch on is only possible when movement
detectors are connected to Trios. This is to prevent lights from automatically switching on at night
when areas are unoccupied.
It is important to note that it is not possible to use dimmable light controllers in daylight switching
applications because their programmed switch-off levels are too low (1.5 x reference level).
Daylight switching applications need relatively high switch-off levels to prevent ambient lighting
levels from dropping below the default reference level immediately after switch off (lights will
otherwise automatically switch back on). It is therefore essential to use non-dimmable Trios light
controllers in daylight switching applications. They are programmed to automatically switch lights
off if the measured ambient lighting level remains higher than 2.2 times the default reference level
for more than 15 minutes
TRIOS
training-manual 1. 2
13
Luminaires connected to non-dimmable light controllers switch on automatically when the light
sensor’s output signal drops below 4Vdc (= reference level) and off when the output signal is
above 8.8Vdc (2.2 x reference level) for more than 15 minutes. The ambient lighting levels
required to generate these control signals are determined by the light sensor’s sensitivity.
Example:
In a daylight switching application with non-dimmable luminaires and light controllers, the light
sensor’s default sensitivity of 22mV/lux causes the lights to switch on automatically when the
ambient lighting level drops below 600 lux. If the requirement for the application is that lights must
switch on automatically when ambient lighting level drops below 500 lux which, in this example, is
assumed to be equal to the installed lighting capacity, the following steps must be followed:
1. Create a lighting level equal to the new switch-on level of 500 lux. Since this is equal to the
installed lighting capacity, it can only be obtained when the lights are switched on at night or
when they are switched on during the day with closed curtains.
When the ambient lighting level is 500 lux, the light sensor’s LED indicator will not be at maximum
brightness because the generated control voltage is lower than Trios’ reference level of 4Vdc (the
light sensor’s control signal drops below 4V dc when the measured light level drops from 600 lux
to 500 lux
2. Change the light sensor’s sensitivity so that it generates a control voltage of 4Vdc at 500 lux
The sensitivity must be increased to decrease the automatic switch-on level from 600 lux to 500
This is done by turning the linear potentiometer clockwise until the LED indicator is fully on
The potentiometer must be turned less than 180° at a time with a 5 second interval between each
increment. If, after an increment, the LED indicator remains on (the control voltage is then above
4Vdc), the sensitivity must be reduced again by turning the potentiometer counter-clockwise in
smaller increments. This process is repeated until the LED indicator just reaches its maximum
brightness.
Once the correct sensitivity is obtained, the lights will switch on automatically when ambient
lighting levels drop below 500 lux (i.e. when the control signal drops below 4Vdc). If the ambient
lighting level remains above 1100 lux (2.2 times the reference level = 8.8Vdc) for more than 15
minutes, Trios will switch the lights off automatically.
TRIOS
training-manual 1. 2
NOTES:
-
If a light sensor plus a movement detector are connected to a Trios controller, lights can be
switched on automatically when movement is detected and daylight levels are insufficiently
high.
-
Automatic switch On is also possible if the light sensor is connected to the Trios controller
(eventually combined with a potentiometer) and if the movement detector input has been
short circuited.
14
TRIOS
training-manual 1. 2
15
Example:
The sensitivity of the light sensor is 22mV/lux and the average reflection coefficient of the area is
30%, the light sensor must measure reflected light below 182 lux (4000mVdc/(22mVdc)) or above
400 lux (8800mVdc/(22mVdc/lux)) before Trios can generate a switch-on or off command
respectively The corresponding ambient lighting levels in the area are 600 lux (182lux/0.3) and
1320 lux (400lux/0.3) respectively. If the automatic switch-on level is too high and should instead
be 500 lux (e.g. the installed capacity of the lighting installation), the sensitivity of the light sensor
must be increased. Lux levels can only be adjusted by potentiometer or IR remote control in
daylight regulation or constant lux applications (with dimmable light controllers and luminaires). In
daylight switching applications with non-dimmable light controllers (e.g. industrial halls), the
automatic switching level can only be changed by changing the sensitivity of the light sensor.
TRIOS
training-manual 1. 2
16
Although it is possible to calculate the required sensitivity to obtain 500 lux (see formulas above),
it is impossible to find the corresponding setting for the potentiometer without additional aids. The
light sensor’s LED indicator must therefore be used when sensitivities are changed.
Daylight regulation and Constant lux (1020/25;1030/35)
Trios becomes very powerful when the light sensor is combined with manual light control in multitask areas like open-plan offices, schools and sporting facilities. With Trios, any lighting level can
be obtained by potentiometer or IR remote control without interrupting automatic light control. The
selected lighting level automatically creates a new reference level for Trios so that energy is
saved for all lighting levels.
The light sensor is used for two types of indoor applications;
- a ‘daylight regulation’ application where artificial light control is directly linked to the
available daylight, and
- a ‘constant lux’ application where an over-installed capacity is eliminated and a
constant lux level is maintained throughout the lighting installation’s life-time.
Daylight regulation:
A dimmable light controller automatically reduces the artificial lighting level when daylight levels
increase and/or automatically switches them off when daylight levels are sufficiently high.
The purpose of daylight regulation is to maintain a defined lux level (reference level) in an area
for optimal working conditions. When the defined lux level cannot be maintained due to increasing
daylight levels, Trios will automatically switch the lights off if the measured ambient lighting level
is 1.5 times higher than the reference level for at least 15 minutes
Since the light sensor’s output signal is limited to 10Vdc, it is possible that Trios cannot generate
a switch-off command if its switch-off level is higher than 10Vdc i.e. if its reference level is higher
than 6.7Vdc. In this case, the lights will remain at their minimum output level and will not switch
off automatically.
Constant Lux level:
A light sensor can also be used to reduce the energy consumption of initially over-designed
lighting installations. When it is combined with a dimmable light controller, the over-design
capacity is eliminated by obtaining the desired lux level immediately after installation. As the
installation’s output deteriorates due to lamp ageing, Trios automatically increases the lighting
level to maintain the desired lux level.
Constant lux applications can only be realised with dimmable light controllers and dimmable
ballasts. The lux level that is required for the application can be defined by potentiometer, IR
remote control, RC5 encoded push-button switches or by changing the sensitivity of the light
sensor.
TRIOS

5. Changing the reference level in Trios.
Trios controller LRC1010
The Trios-reference level (fixed 4V) and the light sensor sensitivity setting together define at
which lux level the lights will switch ON.
The lights will switch OFF at 2.2 times the reference level (=2.2 x 4 Volt = 8.8Volt)
Since the reference level is fixed, the only possibility to change the level at which Trios will switch
the lights ON and OFF is to change the light sensor sensitivity. (see paragraph daylight
switching).
Trios controller 1020/25; 1030/35
Also in these controllers the reference level and the light sensor sensitivity setting together define
at what lux level lights will switch ON.
The lights will switch OFF at 1,5 times the reference level. The reference level in the dimmable
controller is not fixed, but it can be changed by IR commands or with a potentiometer.
If the controllers default reference level (=4Volt) does not produce correct lux levels, it can be
changed with IR transmitters, RC5 pushbutton interfaces or with a potentiometer.
Artificial lights are simply dimmed up or down until the desired lux levels are reached.
This desired lux level, which is a combination of artificial and daylight, is reflected back to the light
sensor. The sensor’s output value is the new (temporary) reference level. (The value will be
stored as the new temporary reference level 5 seconds after the last IR command was given.)
This temporary reference level remains valid until a new IR command or potentiometer
adjustment is generated.
The initial light sensor sensitivity (factory adjustment) has to correspond to the applications
installed light level, other wise it has to be adjusted to adapt to this level.
TRIOS
training-manual 1. 2
It is possible to store 4 preset light-levels in the Trios (dimmable)controller.
This can be done with the IRT8030 handheld transmitter.
To recall these presets, the IRT8030 or the IRT8050 wall transmitter can be used.
NOTE: If you would like to store one of Trios’ four preset memories, the store command should
not be executed on the IRT8030 transmitter earlier than five seconds after the new reference
level has been selected (by the channel keys). Otherwise an incorrect reference level will be
stored.
18
TRIOS
training-manual 1. 2
19
Changing the reference level by potentiometer
When a LPS 100 potentiometer is combined with a light sensor, the reference level in Trios is
always equal to the potentiometer’s control voltage.
Slow light reactions when reference levels are changed.
When reference levels are changed by adjusting the potentiometer, the balance between the light
sensor’s output signal (A) and the potentiometer’s selected reference level (B) is lost temporarily.
Trios’ control program corrects this imbalance by regulating the lights up or down until the
balance is restored (C). It takes some time to change lux levels with a potentiometer because the
result is unknown immediately after each adjustment. The lux level corresponding to the
potentiometer adjustment is only known once Trios restores the balance.
Due to these reaction delay times, a potentiometer in combination with a light sensor should not
be used in applications where a user is able to adjust lux levels. Potentiometers are however,
very useful when the constant lux level in an application must be fixed during normal conditions
and when it has to be easily changed if working conditions change. If for example, 500 lux must
be maintained in an administration office, a dimmable light controller and light sensor can be used
together with push-buttons for manual switching and a potentiometer for defining constant lux
levels. To prevent users from changing reference levels, the potentiometer should be placed
outside the office within easy reach (e.g. in an installation cabinet). In this type of application, a
potentiometer is ideal to obtain the required lux level quickly and accurately during commissioning
without having to climb a ladder to change the light sensor’s sensitivity.
TRIOS
training-manual 1. 2
20
IR remote control for commissioning and for light control
The light controller’s reference level is continuously updated when IR remote control is used.
This can be done by recalling presets or by dimming.
Since the reaction to IR commands are immediate, the desired (reference) lux level is obtained
quickly and efficiently. IR remote control is therefore an ideal commissioning tool for installers or
facility managers who use it to define or adapt an application’s constant lux level. If this lux level
is subsequently stored in the preset memory of Trios (using the IRT8030 hand transmitter), a user
can switch the lights with the IRT8050 wall transmitter (in four different presets) without being
able to change the pre-defined lux levels. If the user is permitted to change lux levels, the
IRT8030 hand transmitter or RC5-encoded push-button switches can be used for maximum
flexibility in light control.
Reference levels can be defined at any time of day The power of this concept is that a reference
level can be defined and stored in Trios at any time of day without worrying about the effect of
daylight levels. Since reference levels are derived from light sensor measurements (= daylight
level + artificial light level) immediately prior to storing, a stored reference level will always obtain
the desired lux level on a working surface.
Recalling preset reference levels
When a transmitter or RC5-encoded push-button switch is used to recall preset 1 then the
associated artificial light output is depending on the amount of daylight at the moment of recalling.
Trios’ control program automatically selects the correct artificial light output based on the inputs of
the light sensor. If for example 500 lux is stored in preset 1, the associated artificial light output is
much lower during daytime than at night (when it is dark).
Working principal of Trios 1030/35.
Preset 1.
If the reference level stored under preset 1 is not sufficient (e.g. 500 lux), lights can be dimmed
up or down until the desired light level is reached (e.g. 750 lux). This is then the new reference
level (daylight + artificial light) at which the artificial lights will regulate.
If a movement detector is installed and lights switch off because no movement is detected; the
lights will automatically switch back on in preset 1 if movement is detected again. This means that
daylight regulation is active.
If lights are switched off manually, they can only be switched back on manually by pressing one
of the four preset buttons.
Preset 2
Preset 3
Preset 4 are adjustable light level presets without daylight regulation possibilities.
E.g. if preset 2 is 500 lux and daylight is increasing the artificial light output remains at 500 lux,
unless the lights are dimmed manually. This means there is not automatic daylight regulation.
If daylight regulation is required preset 1 has to be selected and lights will regulate to the
reference level stored under preset 1.

6. IRT 8030 Infrared remote control
The advantage of IR remote control from an installation point of view is that vertical switching
wires to wall switches are no longer needed. This reduces the initial electrical installation costs
and eliminates future re-wiring costs when partition walls are moved. The user is offered both
flexibility and comfort; lights can be switched and regulated from any point in the room, groups of
luminaires can be controlled independently in both open-plan and modular offices and predefined lighting scenes can be recalled.
Functionality
Four presets can be selected with the four large keys on the front of the transmitter. The fifth
large key is the “all off ” command. This transmitter has five different infrared channels for
individual control of a maximum of five different control circuits. As this function is normally
required only during installation or adaptation of the lighting installation, the necessary keys are
located behind a hinged cover.
A preferred setting of the lights can be stored in the memory of the controller(s).
For incidental changes of system parameters, the transmitter can be switched temporarily into a
“teach mode”. The IRT8030 can then be used as a Trios programming tool, thus offering the
same (programming) functionality as the Trios programming tool IRT1090 and as included in the
remote control transmitter IRT8050.
For an overview of the key allocation refer to figure 1: key functions of the IRT8030

For an overview of the key allocation in “teach mode” refer to figure 2:
key functions of the IRT8030 in “teach mode”.
Operating instructions
General information
The allocation of keys is such that the most common functions can be operated with the large
upper keys and the less common functions with the keys under the hinged cover.
Dimming and switching of individual control circuits and the programming functions in “teach
mode” require a “two-step” operation: First the required channel or parameter must be selected,
then the required operation can be executed or the selected value entered.
The following paragraphs give a short description of the various control functions. Obviously
these descriptions are only relevant provided that this function is supported by the corresponding
control system. For details on specific functions please refer to the documentation on the relevant
control system.
Selecting presets (light scenes)
One out of four presets can be selected directly using one of the four large keys on the front of
the transmitter. Lights can be switched off simultaneously with the fifth large key.
Controlling individual lighting control circuits in Helio and Trios
First the required channel must be selected, then the required operation can be executed.
Channel selection is achieved with the “Select” key. An LED indicates the selected channel.
When the “Select” key is momentarily pressed (less than 1/2 sec.) the led shows the (last)
selected channel. When the key is pressed continuously or repeatedly, the next channels are
selected. This action can be continued or repeated until the required channel has been selected.
If no further keys are pressed the LED’s stay on during 5 seconds after the last key release.
TRIOS
training-manual 1. 2
23
With the "#I" and "$O” keys the selected channel can be switched and /or regulated, as
allowed by the corresponding controller(s). During the actual transmission of infrared signals, the
LED flashes for verification of the selected channel. After transmission the LED is switched off.
Programming presets
The procedure to be followed is:
1. adjust individual control circuits as described before
2. press the “store” key
3. press the wanted preset key
Recall installer presets
At any time the user can revert to the pre-programmed presets as set by the installer, by pressing
the “Recall” key.
Programming Operational Mode, Group Address and Channel Address
For programming the group, or channel, addresses or the operational mode of a controller, the
transmitter must be set in the “teach mode”. This is done by pressing the "#I" and "$O” keys
(under the cover) simultaneously until (after about 3 seconds) a flashing LED (2 flashes per
second) indicates the “teach mode”. The functions of the keys in “teach mode” are shown in
figure 2.
First the parameter to be programmed (group, channel or mode) must be selected, and then the
required value can be entered.
Parameter selection is done with the “Select” key. An LED indicates the selected parameter.
When the “Select” key is momentarily pressed (less than 1/2 sec.) the led shows the (last)
selected parameter. When the key is pressed continuously or repeatedly, the next parameters are
selected. This action can be continued or repeated until the required parameter has been
selected. If no further keys are pressed the LED’s stay on during 5 seconds after the last key
release.
The value required is programmed by pressing the appropriate upper key (0-9 / A-G). The
transmitter sends the codes that set the appropriate address or mode of the controller.
During the transmission of the programming instructions, the infrared indicator LED will flash
rapidly. When finished it returns to slow flashing. Also the function indicator LED will flash, thus
showing the actual function. After programming is completed, the transmitter can be reset to
normal operation by pressing the "#I" and "$O” keys again until the LED’s will switch off.
The transmitter will revert to normal operation automatically 1 minute after the last key press.
NOTES:
1. When transmitting in “teach mode”, the infrared radiation pattern of the IRT8030 is
reduced to a narrow beam, in order to achieve selective programming of luminaires or
controllers. Therefore the transmitter must be pointed directly at the receiver and the
distance from transmitter to receiver must be less than 3 meters. (See figure 3)
2. All commands of the Trios teaching mode are transmitted in the “general” group, in order
to assure proper reaction regardless the group address of Trios.
IR channel addresses
It is important in some IR remote control applications that a single transmitter is used to control
several clusters of luminaires independently. In a large, multi-task office for example, the
luminaires along a window, above a desk and above a meeting table have to be controlled
separately to obtain the required lighting level for a specific task. This is done by connecting each
luminaire cluster to its own Trios light controller and by giving each light controller a channel
address. The channel control keys on the transmitter can then be used to control each luminaire
cluster separately. Maximum 5 different addresses are possible.
TRIOS
training-manual 1. 2

IR group addresses
If IR remote control is used in multi-user areas like open plan offices, it is essential to limit light
control to defined areas. This is done by giving Trios light controllers’ in each sector a group
address. A transmitter with address A will only control the luminaries connected to light controllers
with the same address and will not interfere with light controllers with other address numbers.
A maximum of 7 groups (each having a maximum of 5 channels) is possible.
The figure gives a typical example of an open-plan office sub-divided into seven sections with
independent light control in each section. Using the IR functions, lighting scenes can be
customised for different tasks in each office section
Transmitters also have a General Group address (ALL GROUPS) enabling them to control all the
light controllers irrespective of their group address. Transmitters set to the General address are
especially useful for night cleaning or night patrol purposes when lights anywhere in the building
have to be controlled by a single person.
The Trios teach mode is used to define the channel and group address in the light controllers by
IR remote control.
Presets Lighting levels that are needed more often can be stored in the light controller’s preset
memory with a transmitter. The transmitters preset keys are used to recall predefined lighting
levels ( single-channel applications) or predefined lighting scenes ( multi-channel applications)
quickly and efficiently when lights have to be adapted for specific tasks. The figure shows an
example of four preset lighting levels stored in a light controller with a channel 1 address.

Changing channel and group addresses of Trios light controllers
The Figure illustrates how to change the channel and group addresses of light controllers in an
office with multi-channel control.
Changing the channel address
If the light controllers are interlinked, as in this example, first disconnect the interlink cables.
Connect an infrared receiver to the controller that needs to be addressed.
To change the channel address, point the transmitter to the IR receiver and press the required
channel address key (1 - 5). Trios will confirm a successful programming action by a double state
toggle of the output.
Repeat this procedure for all light controllers that need to be addressed.
Finally re-connect the interlink cable and the sensor.
Changing the group address.
The group addresses of the light controllers have to be set to group address (B).
If the light controllers are interlinked and connected to an infrared receiver, the group address of
all controllers can be changed at ones. To change the Trios light controllers group address, point
the Trios programming tool towards the IR receiver and press the required group address key (A G). Trios will confirm a successful programming action by a double state toggle of the output.
Communication between programming tool and light controller.
In order to communicate with each other, the light controller and the Trios programming tool must
have the same group address. Normally the programming tool is (factory)set to the “general”
group. Therefore all Trios controllers will react (irrespective of its own group address A-G). The
reaction of Trios can be tested by using the ‘ALL OFF’ and ‘Preset 1’ key on the programming
tool.

Manual / Remote control
There are four manual control possibilities with TRIOS light controllers:
- IR remote control with IRR8124 receivers and IRT8030/IRT8050 transmitters,
- multi-functional control with push-button switches and push-button interface,
- basic toggle switching with push-button switches and
- dimming with LPS100 potentiometers.
The manual control options can be used separately or combined with other types of sensors, like
movement detectors, light-sensors and potentiometers.
In the following sections a detailed description is given of the functionality of all possible sensor
combinations.
Since IR remote control and RC5 encoded push-button switching are functionally the same, no
distinction is made between the two when they are discussed in combination with other
peripherals. The push-button interface however has four extra toggle functions

Trios controller with only a light-sensor, or a light-sensor in combination
with a potentiometer
If the peripherals connected to a Trios light-controller consists of only a light sensor, or a light sensor in
combination with a potentiometer, special care must be taken.
The light controller will not switch On if only a light sensor is connected. Therefore the movement detector
input (pin 2 and 6 of the telejack plug) has to be short circuit.
