ABB solutions to manage
the lighting circuits, according to a precise
value of ambient light.
T Line twilight switches and TWA astronomical twilight switches
Saving and efficient use of energy for public lighting.
To control the automatic activation of
a lighting circuit to variations in natural
light, an environment, and thus to ensure
an efficient use of energy, ABB offers a
full range of performance and twilight
switches predisposed to solve the most
common to more complex application
situations in the control of lighting
circuits.

The constant investment to research and development, make
ABB a point of reference in the production of cutting-edge
products that fully reflect the installation requirements of even
the most demanding customer. ABB’s goal is to provide the
market with innovative products in terms of design, energy
saving, safety, functionality and environmental impact. The
high performance, highest reliability, quiet operation and a
compact design, are among the main characteristics that
distinguish “T Line” twilight switches and “TWA” astronomical
twilight switches.
T Line twilight switches command
lighting circuits according to the
scheduled level of the ambient light
detected by a dedicated sensor.
Since they are energy-efficient, they
are particularly useful in public places
(garden, parking lots, entrances,
courtyards, etc…).
T Line twilight switches range allow to switch ON and switch
OFF lighting devices according to a scheduled level of the
ambient light. They are used in combination with a sensor to
detect if the ambient light is higher or lower than the set level.
A switching delay prevents them from operating unnecessarily
when the light intensity suddenly changes (e.g. lighting,
moving vehicles, etc..).
The control automated of lighting
provides more than 15% of energy
savings
The basic version T1 in one channel, is preset a 10 lux from
factory and is equipped with 2 signaling LEDs that indicate the
set point value and display the status of the contact. The
operating instructions are printed on the side of the product.
The advanced version T1 PLUS, switches feature a setpoint
that can be adjusted for 4 different scale values:
The advanced version T1 PLUS, switches feature a setpoint
that can be adjusted for 4 different scale values:
- 2…40 Lux
- 20…200 Lux
- 200…2000 Lux
- 2000…15000 Lux
This make them ideal for daytime applications where the lux
values to detect is very high. T1 PLUS allows also the possibility
to adjust the relay tripping in a time ranging from 15-90 sec.
for switching ON and 20-120 sec. for switching OFF. They are
equipped with 2 signaling LEDs that indicate the setpoint value
and display the status of the contact.
The TWP version is designed for installation on the pole /
wall, with photocell inputs and integrated cabling including
cable gland seals to ensure a high protection degree. Thanks
also to the high quality, TWP provides excellent resistance
to atmospheric agents and a long service life. TWP is also
equipped internally with a preset sensor of 10 Lux. TWP is the
ideal solution to management the external light systems such
as the public ones, more precisely, in cases where there is a
need of having to control the lighting of public or private roads,
gardens, courtyards to the decline of solar radiation during
precisely the twilight.

High performance and long-term reliability
The twilight astronomical switches TWA-1 and TWA-2,
respectively, in 1 and 2 channels, they automatically control
lighting circuits depending on the time of sunrise and sunset,
greatly increasing energy efficiency.
More than 30% of energy saving, thanks
to the automatic shut-off lighting when
not needed.
The programming is in fact based on a mathematical
algorithm able to calculate the time of the rising and setting
of the sun in a certain location for each day of the year. Once
powered the device, simply insert date, time, geographical
coordinates and time zone because it is ready to work.
The installation of these devices is particularly useful
when using a twilight switch with external probe is not
recommended because it may be subject to malfunctions
caused by air pollution, excessive brightness or vandalism.
TWA-1 and TWA-2 are also indicated for the control of public
lighting, shop windows of shops, neon signs, monuments,
facades and illuminated fountains.
The twilight astronomical switches TWA-1 and TWA-2, can
be programmed directly on your PC using the software
Handytimer. Once created, the program can be transferred
to the programming key and copied into multiple devices,
avoiding any errors in reprogramming.
Minimal configuration:
– Operating system Microsoft Window 95, 98, 2000, NT, Millennium, XP
– Memory 15 Mb of free hard disk space
1a - Connect the USB cable to the programming interface device
and to your PC
1b -Insert CD, install the HANDYTIMER software with easy step by step
instruction
1c -C reate the required program
2a - Insert the DT-VK memory key into the programming interface device
2b -C opy the program on the DT-VK memory key

Crepuscolari Linea T | 9
Twilight switches T1
Operating principle
The diagram shows an example of the installation of the
T1 twilight switch in the lighting system of a commercial
establishment. When the external light falls below a certain
level (e.g. during the evening when the shop is closed), the
device switches on the window lights and the shop sign.
The lights can be switched off late evening to reduce power
consumption thanks to the AT1 switch timer.
Installation example
As shown in the diagrams, one of the possible applications
is the installation of a T1 twilight switch in the lighting system
of a commercial establishment. When the external light falls
below a certain level (e.g. when the shop is closed), the
twilight switch switches on the window lights and the sign.
The lights can be switched off late evening to reduce power
consumption thanks to the AT1 switch timer which keeps the
circuit open until the next morning. When the external light
returns to above the threshold value, the twilight switch relay
returns to the open position.

Application environments
The installation of the T1 twilight switch with an AT

etc.).

Twilight switches T1 PLUS
Operating principle
The diagram shows an example of the installation of the T1
PLUS twilight switch in the lighting system of a greenhouse.
When the external light exceeds a certain level (e.g. during
the warmest hours of the day, i.e. early afternoon), the device
activates the shading system, e.g. roller blinds. Thanks to the
option to advance or delay the activation-deactivation time,
the T1 PLUS can also maintain the roller blinds closed in the
case of passing clouds.
AUXILIARIES
N
external sensor
Installation example
As shown in the diagrams, one of the possible options is to
install a T1 PLUS twilight switch in the lighting system of a
greenhouse. When the external light exceeds a certain level
(for example during peak hours in the early afternoon) the
twilight switch activates the roller blinds, protecting the plants
in the greenhouse against burning by the strong sunlight.
When the external light returns to below the threshold value,
the twilight switch relay opens the blinds to allow the sunlight
to pass through.
Application environments
The installation of the T1 PLUS twilight switch is particularly
useful in settings and situations where lighting control is
required for locations where there are consistently high
brightness values, thus guaranteeing substantial savings in
energy consumption (greenhouses, arcades, photovoltaic
plants, etc.).

Twilight switches T1 POLE
Operating principle
The diagram shows an example of the installation of the
pole mounted T1 POLE twilight switch for motorway lighting
systems.
When the external light falls below a certain level, 10 lux for
example, the device switches on the lights present in tunnels,
service areas, near to junctions, etc. The lights are then
switched off by the T1 POLE in the morning when the 10 lux
value is exceeded.

Installation example
As shown in the diagrams, one of the possible applications is
the installation of a T1 POLE twilight switch in the motorway
lighting system. When the external light falls below a certain
level (for example at sunset), the pole-mounted twilight

Astronomical twilight switches TWA
Operating principle
The installation of an astronomical twilight switch in a system
is a particularly useful addition for settings and situations in
which light sources, or other environmental conditions, can
cause changes in the brightness level and falsify the reading.
In these cases, the TWA-1 and TWA-2 astronomical switches
can control the lighting system according to the sunrise and
sunset times of the geographic zone in which the system is
installed.

Example of installation
Atmospheric pollution is one of the causes of a reductions in
the level of environmental light. Dust deposits on the external
probe of a traditional twilight switch can compromise the
operation of the device, preventing it from automatically
switching off the controlled lighting system in the presence of
external light. As shown in the example, this problem can be
resolved by installing a TWA-1 astronomical twilight switch
that controls the lighting system according to the level of light
calculated from the preset longitude and latitude parameters.

Application environments
The installation of the TWA-1 and TWA-2 astronomical
twilight switches is particularly suitable for applications in
which the operation of a twilight switch with external probe
can be falsified or compromised by external agents (such as
environmental pollution, overexposure to light, vandalism, etc.).

FAQ and problem solving
Why factory calibrated to 10 Lux?
Public lighting plays a crucial role in the social life and
represents a mandatory investment for local administrations,
without any direct economic return. They must, therefore, try
to optimize such investments and how they are managed,
while ensuring an efficient service. Because they are factory
calibrated to 10 Lux, the standard value for street lighting,
ABB twilight sensors are immediately ready for application in
public lighting and do not require any adjustment.
Once the twilight sensors have been installed, do they
require any special maintenance over time?
Yes, at least once a year you need check the operating state
of the circuit-breakers and clean the sensors.
Can the twilight sensor be installed near the lights that it
controls? When the lamp switches on in the evening, with
the light on will the twilight sensor switch it off again?
It is always better to avoid the problem by distancing the
twilight sensor from the lights, thus ensuring that the twilight
sensor will be located in a shadow cone and avoiding the
lamps being activated by mistake.
Can more than one sensor be connected with models T1
and T1 PLUS?
No, one sensor must always be used for each device.
Can different types of sensors be connected with models
T1 and T1 PLUS?
No, the only sensor allowed is the LS-D type.
When must an astronomical time switch be used?
When the length of the connection between the device
and sensor exceeds 100 m, or when the connection is too
complicated (e.g., switchboard installed in a cellar).
When the sensor cannot be installed away from light sources
(amusement parks, camp sites, etc.). When external agents
prevent the sensor from functioning correctly, e.g. pollution or
vandalism.
