5TE8 control switches
■
Overview
Two-way switches are used in control cabinets and distribution
boards for switching small loads on/off or over.
Group switches with center position permit the positions
open/stop/closed, for example to control counter-clockwise
rotation – Off – clockwise rotation.
Control switches in a range of contact versions have an integral
control lamp for the ON setting.
The auxiliary switch (AS) signals the contact position of the
switch. It has the same design as the auxiliary switch used for
the miniature circuit breakers (see Catalog LV10, chapter
"Miniature circuit breakers").

5TL1 On/Off switches
■
Overview
The new 5TL1 ON/OFF switches are used for the switching of
lighting, motors and other electrical devices. Rated currents
range between 32 A and 125 A. The new design of the
5TL1 ON/OFF switches allows them to be optically perfectly
integrated in the series of RCCBs and MCBs.
In addition, the 5TL1 device versions can be used as switch
disconnectors according to EN 60947-1 and serve as main
control switches for the disconnection or isolation of plants
according to EN 60204-1.

Configuration
For DC voltages up to 1000 V, the four poles need to be
connected in series. In contrast to normal flush-mounting
switches, these devices are also fitted with arcing chambers and
permanent solenoids to aid the positive quenching of the
electric arc in direct currents.
For this reason it is essential to comply with the polarity
specifications of the switches when connecting the conductors.
Suitable precautions should be taken during plant configuration
to ensure there can be no polarity reversal in DC operation.

Busbars for 5ST modular installation devices
■
Overview
Siemens has developed a rail-mounting concept which makes
the linking of switching devices just as easy as that of miniature
circuit breakers.
The arrangement of the terminals on the devices is adapted
to the bus mounting. With only two busbars, this saves
considerable mounting time.

5TT4 remote control switches
Switching Devices
■
Overview
Remote control switches are used in residential and non-
residential buildings, as well as the switchgear engineering
sector. They trip in the event of "current inrushes", i.e. pulses,
and then electromechanically save the switching position, even
in the event of a power failure.
All the devices have the VDE mark and can also be equipped
with an additional auxiliary switch. All devices have a switching
position indication and are operated manually. The switching
noise is particularly quiet and meets the requirements of
residential buildings.
Note:
Busbars to match the 5TT41 remote control switches can be
found on page 17.

More information
Mechanical storage
Remote control switches are used to switch lighting through the
use of several pushbuttons. This makes complex cross/two-way
switching unnecessary. With each pushbutton impulse, the
remote control switch changes its contact position from "OFF"
to "ON", etc. In the event of a power failure, the last switching
position is mechanically stored. Electromechanical remote
control switches have no standby loss.
Pushbutton malfunction
Pushbuttons can jam and then supply continuous voltage to the
remote control switch. All remote control switches are protected
against this type of malfunction through their design or through
PTC.
Central switching functions
Versions with central ON/OFF function allow the central
switching of all connected remote control switches. This type of
central switching can also be actuated using a time switch. All
remote control switches can be switched to the ON or OFF
switching state, regardless of their current switching state.
Contact sequences
1 – 2 – 1+2 – 0 or 1 – 0 – 2 – 0 means:
0: No contact closed
1: Only contact 1 closed
2: Only contact 2 closed
1+2: Contact 1 and contact 2 are closed
The contact positions are constantly changing with each
pushbutton impulse.
Note:
Synchronous switching of the contacts cannot be guaranteed
with parallel switching. Products with central/group switching
must be used for the mutual control of several remote control
switches.
Bus mounting
• All 5TT41 remote control switches can be bus-mounted with
each other. This saves time and space.
Note:
Busbars to match the 5TT41 remote control switches can be
found on page 17.

5TT4 remote control switches
Typical circuit for 5TT4122-0
with central On/Off switching
With the 2 pushbuttons "central ON" and "OFF", all remote control
switches can be switched on or off from a central point, e.g. at
the start and end of operation. A time switch with a one-second
pulse (e.g. 7LF4444-0) can also be used if desired. Once a
central on/off switching operation has been executed, the
remote control switches can also be switched on and off locally
at any time. Remote control switches with central ON/OFF
switching can also be used to quickly and easily set up a panic
circuit/panic lighting using conventional installation methods.
The input terminals on the remote control switch need to be
connected to the same phase (L1, L2 or L3) and over the same
residual current protective device. Otherwise residual current
protective devices may be tripped unintentionally, or short
circuits might occur.

5TT4 remote control switches
Switching Devices
Typical circuit for 5TT4152-0 with central ON/OFF switching and ON/OFF group switching
With the 2 pushbuttons central "ON" and "OFF", all remote control
switches can be switched on or off from a central point, e.g. at
the start and end of operation.
With the 2 pushbuttons group "ON" and "OFF", all remote control
switches assigned to a group can be switched on or off, e.g. in
a corridor. A digital 7LF44 time switch with a switching command
of 1 s can also be used for the "Central" or "Group" function.
Once a central on/off switching operation has been executed,
the remote control switches can also be switched on and off
locally at any time. The phase relations of ZA, ZE and GA, GE
and L can be different. If contact 1/2 is used as checkback
contact for the central "ON" and "OFF" function, as shown above,
terminal 1 of all remote control switches must be in phase.
Typical circuit: Glow lamp load and 5TT4920 compensator
The use of multiple illuminated pushbuttons, in particular
230 V AC glow lamps, could cause the remote control switch to
trip accidentally, or no longer drop out, due to the current used
by the lamps. This may also occur at high line capacities. By
connecting a 5TT4920 compensator in parallel to the coil, the
glow lamp load of the remote control switch is increased from
5 mA to 25 mA. Several compensators can be connected in
parallel. The power consumption of 230 V 5TG73.. glow lamps
for pushbuttons is: Low luminosity 0.18 mA – medium 0.9 mA –
high 1.35 mA; the power consumption of LED 5SG735. lighting
is approx. 1.5 mA.
To reduce capacitive coupling due to long cable lengths, we
recommend using shielded cables. Particularly in systems with
frequency converter controlled motors or with parallel cable
routes (e.g. cable support systems), the induced current may
impair the function of the devices.

5TT50 Insta contactors, AC/DC technology
Switching Devices
5TT5 Insta Contactors
■
Overview
The Insta contactors are the ideal switching device for
controlling AC/DC control voltage in industrial applications and
infrastructure.
In addition to their basic function, they can also be used for the
ON/OFF switching of single-phase and three-phase electrical
motors. The 5TT50 Insta contactors meet the requirements of
EN 60947 and are approved to UL 508.
The simultaneous switching of lamp loads at varying phases can
be achieved with a single contactor, whereby it is essential to
strive for/ensure a symmetrical load of the phases. Upstream
short-circuit detection devices must disconnect at all poles or
must be equipped with phase failure detection. Violations of the
specified capacitor load limits may cause excessive inrush peak
currents. The level of inrush peak currents is also affected by the
following factors:
• Length and cross-section of the installed supply lines
• Type of electronic ballasts
• Brand/make of lamp
• Insta contactors with O/I automatic function enable the testing
of a plant via manual switch without the need to apply a control
voltage
• Switching position indication for fast recognition of operating
states offers greater safety when checking the plant

More information
Mounting position of Insta contactors, AC/DC technology
The installation of the devices is permissible in the positions
shown in the following diagram (0° to 90°, 270° to 0°). There are
no restrictions when the devices are installed in these normal
mounting positions.
Heat dissipation
If several Insta contactors with AC magnet system are mounted
in series in a distribution board, there are no restrictions for the
types 25 A, 40 A and 63 A within the permissible ambient
temperature range up to 55 °C. For 20 A types within the
temperature range up to 40 °C, a 5TG8240 spacer must be
installed after every third Insta contactor, and in the temperature
range above 40 °C to 55 °C, after every second contactor.
Manual switching with O/I/Automatic function
The 5TT50... versions also offer manual switching. The knob
allows preselection of 3 positions:
• Knob in the "AUTO" position
Automatic mode normal protective function
• Knob in the "I" position
Continuous operation switched on manually
(without control signal; when a control signal is applied,
manual switching on is unlocked, i.e. the knob is automatically
reset to the "AUTO" position)
• Knob in the "O" position
Off switched off
(coil circuit interrupted)
System test without applying a control voltage
Insta contactors with O/I/Automatic function enable the testing of
a plant by manual switching without the need to apply a control
voltage.
Automatic resetting through control signal
When applying a control signal to the terminals A1 and A2, the
Insta contactors can be reset from continuous operation mode
("I" position) to automatic mode ("AUTO" position).

5TT5 Insta Contactors
■
Overview
The 5TT58 Insta contactors are equipped with an AC magnet
system and are ideal for use under harsh conditions. The
auxiliary switches can be mounted without tools. When
equipped with terminal covers, the devices can also be sealed.
Insta contactors without manual switch
Insta contactors are ideal for a wide range of uses in industry,
such as for motors where distribution technology plays a major
role, e.g. in installations for heat pumps and air conditioning
technology. In addition to their basic function, they can also be
used for the on/off switching of single-phase and three-phase
electrical motors.
Insta contactors with manual switch
Insta contactors with manual operation can be switched on and
off by hand.
• Extremely long service life of 3 million switching cycles
• Safe cable routing through the cable entry funnel
• Insulated right through to the cable entry funnel
• Auxiliary switches can be retrofitted on all versions – even on
the 20 A type
• Insta contactors with O/I/Automatic function enable the testing
of a plant by manual switch without the need to apply a control
voltage
• Switching position indication for fast recognition of operating
states offers greater safety when checking the plant

More information
Mounting position, Insta contactors, AC technology
The installation of the devices is permissible in the positions
shown in the following diagram (0° to 90°, 270° to 0°). There are
no restrictions when the devices are installed in these normal
mounting positions.
Heat dissipation
If several Insta contactors with AC magnet system are mounted
in series in a distribution board, there are no restrictions for the
types 25 A, 40 A and 63 A within the permissible ambient
temperature range up to 55 °C. For 20 A types within the
temperature range up to 40 °C, a 5TG8240 spacer must be
installed after every third Insta contactor, and in the temperature
range above 40 °C to 55 °C, after every second contactor.
Manual switching with O/I/Automatic function
The 5TT58...-6 and 5TT58...-8 versions also offer manual
switching. The knob allows preselection of 3 positions:
• Knob in the "AUTO" position
Automatic mode normal protective function
• Knob in the "I" position
Continuous operation switched on manually
(without control signal; when a control signal is applied,
manual switching on is unlocked, i.e. the knob is automatically
reset to the "AUTO" position)
• Knob in the "O" position
Off switched off
(coil circuit interrupted)
System test without applying a control voltage
Insta contactors with O/I/Automatic function enable the testing of
a plant by manual switching without the need to apply a control
voltage.
Automatic resetting through control signal
When applying a control signal to the terminals A1 and A2, the
Insta contactors can be reset from continuous operation mode
("I" position) to automatic mode ("AUTO" position).

5TT3 soft-starting devices
Switching Devices
■
Overview
Soft-starting devices are rugged electronic control devices for
soft starting of three-phase asynchronous machines. By means
of phase-angle control, two of the motor's three phases are
influenced in such a way that the current in these phases rises
constantly. The motor torque behaves in the same way during
start-up. This ensures that the drive can start without jolting. This
rules out damage to drive elements because the starting torque
does not rise abruptly on direct activation. This characteristic
permits a low-cost design of the drive elements.
A clear reduction in starting noise can also be witnessed.
On belt conveyor systems, sliding or tilting over of the goods
conveyed is avoided. After starting, the power electronics is
bypassed by means of an internal relay contact to minimize
losses in the device.

Overview
Switching on loads
The increased making currents of different loads and thus the
risk of contacts welding is often underestimated.
Resistive load:
The resistive load, e.g. electric heating, does not increase the
making current.
Incandescent lamps:
The cold coiled filament in incandescent lamps or halogen
lamps causes a 6 to 10-fold making current for approx. 10 ms.
Uncorrected fluorescent lamps:
When switched on over several periods, the heating current of
the coiled filament and the operational current produce a 2 to
2.5-fold inductive current.
Fluorescent lamps with parallel compensation:
When switched on, the capacitor causes an extreme, up to
13-fold, current for approx. 10 ms.
Fluorescent lamps in duo connection:
The series capacitor results in compensation. In spite of this, an
increased making current is produced over several periods, just
as for uncorrected fluorescent lamps.
Selecting contacts for lighting systems
A wide range of different contacts are used for modular
installation devices:
• Contactor contacts with a > 3 mm contact gap, as in
Insta contactors, AC technology
• Switching relay contacts with m contacts (contact gap
> 1.2 mm but < 3 mm)
• Manually operated contacts with > 3 mm contact gap, as for
5TE8 switches
• Relay contacts with contacts (contact gap > 0.5 mm), as are
used on PCBs with electronic devices.
The selection tables in the Technical Specifications will help you
to find the correct switching device for the different lighting
installations.
Switching off loads
If a contact with current flowing through it opens, this always
ignites an electric arc above 24 to 30 V. This arc depends on
voltage, length of isolating distance, speed of contact, actuating
angle and amperage. The principle of the so-called zero cutoff
is that after no more than 1½ half-waves, the electric arc is
quenched in the zero point. There are no further quenching aids
or current limiters, as is the case with miniature circuit breakers.
Switching off direct currents
When switching direct voltages, there is no zero passage of
current for the arc to be interrupted. To be able to switch
significant currents despite this, contacts are connected in
series to increase the isolating distance.
Some switching devices are provided with planning data for
switching direct currents. Compliance with these planning data
is essential. If the data values are exceeded the electric arc is
not reliably quenched and there is a risk of fire.
Safe separation
When operating 230 V and safety extra-low voltage SELV –
voltage of bell transformers or transformers for permanent
load – on a device, it is essential to ensure "safe separation".
At least 8 mm of creepage and air clearances and a withstand
voltage of more than 4 kV is needed for this. If these conditions
– 8 mm or 4 kV – are not fulfilled, the term "electrical separation"
as "not SELV" is used instead of the term "safe separation".

Overview
Today, time switching is a matter of course.
In fact, it is now hard to imagine many process sequences and
energy saving processes without time switching. It could also be
argued that time switching satisfies a basic need in the electrical
installation sector.
New-generation digital time switches have a wider variety of
functions than their predecessors and are easier to operate,
thanks to better possible solutions.
They can be used to switch systems or devices or for functions
such as: Irrigation plants, hothouses, garden systems,
swimming pools, filter systems, canopy controls, break signals,
bell chimes, shop-window lighting, illuminated advertising,
sports-hall lighting, traffic-light controls, street lighting,
illuminated signs, office lighting, stairway and entrance lighting,
object lighting, preheating of industrial furnaces, injection-
molding machines, ovens, heating systems, air-conditioning
systems, fans and ventilation systems, heating and circulating
pumps, and sauna systems.
The devices have the VDE mark and are UL approved
(not 7LF4444).

More information
Mini digital time switch
The Mini digital time switch with a width of only 1 MW and its
hourly, daily and weekly program is ideal for replacement and
installation in distribution boards with limited space.
The Mini digital time switch can be used flexibly as it can also be
operated in battery mode with all its functionalities. Furthermore,
the actuator of the clock can be removed from its enclosure for
easy programming over the 5-way joystick prior to mounting.
Top, Profi, Astro and Expert digital time switches
Whether you are using text-assisted programming directly on the
device or user-friendly programming on the PC, the Top, Profi,
Astro and Expert digital time switches will make your work
quicker and easier.
Simple operation:
Four programming keys offer user-friendly assistance with a text
menu.
Display that is easy to read:
If you have to change the setting on the digital time switch inside
a dark control cabinet, the integrated backlit display and
illuminated control elements ensure that you retain an overview
of what is what.
Straightforward commissioning:
You can start programming immediately. Profi, Astro and Expert
are supplied with the time, date and automatic daylight savings
for Central Europe already set.
Clear contrast:
In order to retain an overview even if lighting is poor and
temperatures extreme, the display contrast can be adjusted,
practically down to the finest detail.
User-friendly programming:
Operating and programming a digital time switch has never
been so simple, straightforward and user-friendly.
1-channel time switches allow input of up to 56 switching
programs, 2-channel time switches allow up to 28 programs per
channel and 4-channel time switches up to 84 programs per
channel. This means that the Profi, Astro and Expert time
switches are ideally equipped for even the most complex of
tasks.
Each entry required is clearly indicated so no prolonged
studying of the operating instructions is required. A particularly
practical feature is that the digital time switch can be
programmed when not connected to a supply voltage.
The Profi, Astro and Expert digital time switches offer more than
reliable switching. Numerous integrated, easy-to-use functions
ensure that these problem solvers are as simple to operate as
they are versatile.
A data key enables easy programming of the Profi, Astro and
Expert digital time switches at a PC, simplifies the setting of time
switch programs and saves enormous amounts of time. This
prevents human error and enables simple copying of complete
time switch programs to different time switches.
Astro function:
The Astro and Expert time switches have one key strength: the
Astro function. The exact time of sunrise and sunset is available
for every location and every day in the year. For example, this
means that connected exterior lighting only switches on when it
gets dark – on short winter days as well as summer days, when
it is light for much longer. The advantages are clear:
• Cost-savings, because electricity is only used when the
lighting is really needed, and because this prolongs the
service life of the lighting itself. Particularly in the case of dusk-
dependent lighting controls
• Safety and convenience, because the light is always switched
on when it is dark
• Ease-of-use, because the digital time switch does not have to
be reprogrammed throughout the year
• Simplest possible installation, as the Astro digital time switch
works in the distribution board. No further need for laborious
cable laying to the light sensors. This means that it is not
necessary to lay cables across the lightning protection zones.
The compact 2-WM range is also ideally suited for subsequent
installation or replacement.
It goes without saying that the Astro and Expert digital time
switches do not just switch at dawn and dusk; complex,
combined programs are also possible. You always have the
choice between astronomically calculated and individually set
switching times, or a combination of both.

7LF4 digital time switches
Switching Devices
7LF, 5TT3 Timers
PC programming:
The Profi, Astro and Expert digital time switches support plug-in
data keys, thus providing you with even more security and
convenience.
For example, you can read a program out from a digital time
switch via the data key, copy the program to the PC and save
and edit it there – or you could just transfer it to another clock.
You can also work with several data keys. Programs can then be
changed in a matter of seconds.
A backup copy ensures faster service. If the time switch has
been manipulated, the data key can be used to retransfer the
saved program to the clock without any problem.
Thanks to the standard operator interface, based on MS Office,
there is no need for laborious program training.
Pulse function on a 1-channel device:
Up to 84 start times and one pulse time can be programmed on
the time switch using the pulse function. The pulse duration can
be selected between 1 s and 59 min 59 s.
Random function:
If the random function is activated, the set switching times are
shifted at random within a range of ± 30 min.
Operating hours counter:
Particularly in commercial applications, it is often necessary to
determine the operating life of the switched load, e.g., lights. The
operating hours counter displays the total ON duration per
channel and the date of the last reset.
Holiday function:
The start and end dates of the holiday period are set in the
holiday program. If the holiday program is activated, the digital
time switch does not carry out any programmed switching
commands during the relative period but, depending on the
respective input, is set to "CONTINUOUSLY OFF" or
"CONTINUOUSLY ON" during the holiday period. Once the
holiday period has elapsed, the digital time switch again begins
to perform switching automatically in accordance with the
programmed switching times.
Control input:
The follow-on time that can be set in the control input enables the
relay to be switched in addition to and in parallel with the
switching program. The follow-on time can be set within the
range 0 min ... 23 h 59 min, and begins as soon as the voltage
on the control input drops.
1 h test:
The "1H TEST" function can be used for simulating switching.
If "1H TEST" is activated, the switching outputs are switched for
one hour. Once this period has elapsed, the digital time switch
again begins to perform switchings automatically in accordance
with the programmed switching times.
PIN code:
Input and programming can be disabled using a four-digit
PIN code.
Week programs:
Programs that are designed to be repeated regularly every
week, e.g. light control, heating control. A week program
comprises an ON/OFF time and assigned ON/OFF days.
Year programs:
Programs that are only to be executed within a defined period of
validity. They overlap with the week programs of the same
channel according to an OR operation. The period of validity is
specified by entering the start/end date. Validity from start date
00:00:00 to end date 24:00:00. The start date must be prior to
the end date. Within their period of validity, these programs act
as week programs. Outside their period of validity, these
programs have no influence on the switching behavior.
Exception programs:
Have a higher priority than week and year programs. Week and
year programs of the same channel will not be executed within
the period of validity of an exception program. However, within
the period of validity other exception programs will be executed.
The different exception programs overlap according to an OR
operation.
Cycle function:
On the year time switch, channel 1 has an additional option for
"cyclic switching". The term "cyclic switching" means that within
a specific period, the time switch is switched on for a specific
duration (ON time). The cycle time can be set between
2 seconds and 2 hours. The ON time can be set between one
second and one hour.

Overview
Today, time switching is a matter of course.
Making energy savings by means of time switching has become
a matter of course. Nowadays, many process sequences would
be inconceivable without time switching.
If the minimum switching interval is sufficient, mechanical time
switches are always used. The press-down tabs can be set to a
minimum interval of 15 minutes, without the need to use a tool.
They can be used to switch systems or system components or
for functions such as: Irrigation systems, greenhouses, public
gardens, swimming pools, filtering installations, canopy
controls, church bells, shop window lighting, advertising
lighting, gym lighting, traffic signal controls, street lighting,
illuminated signs, office lighting, lighting of stairwells and
entrances, object illumination, preheating of industrial furnaces,
spraying machines, ovens, heating systems, air-conditioning
systems, fans and ventilation systems, heating and circulation
pumps and sauna systems.
All devices have the VDE mark and are approved to UL.

More information
Mechanical time switches with day disk
Synchronous time switches without power reserve
The control gear is driven by a synchronous motor so it is
dependent on the power supply frequency. If this frequency is
unstable, the devices cannot be used. In the event of a power
failure, the time switch will stop.
Quartz-clock time switches with power reserve
A quartz electronic circuit supplies the drive with a stabilized
frequency so that the time switch is not dependent on the power
supply frequency. In the event of a power failure, the time switch
continues to operate on its power reserve.
Automatic setting function
This makes installing the 7LF5301-4 and 7LF5301-5 time
switches quick and easy. These time switches self-adjust during
commissioning in fast mode to the correct time and correct day
within the Central European zone. The relevant daylight-saving
adjustment is also made automatically. Another advantage is
that, once the supply voltage is reconnected following a power
failure, the correct time and day are reset using quartz precision.
Precision quartz clockwork
Accuracy: The internal precision clockwork has an accuracy of
1 min. per year. Until now, this level of accuracy and automatic
operational safety was only possible using digital time switches.
Optimization of power consumption due to minimum make and
break cycles of 15 minutes: it is possible to set the switching
times in 15-minute patterns, with a switching interval of at least
30 minutes.
Mechanical time switches with week disk
LED display
Adjustment data for Central Europe are stored in the switch and
an LED display provides information about the current status.
So, all you have to do is unpack, snap on, connect, and set the
desired switching times, all without the need for tools. This saves
time and money.
Clear design
The clear design aids understanding. Switching times can be
easily identified.
As regards the weekly time switch, a minimum switching interval
of 240 minutes results in a switching step of only 120 minutes.

Typical circuit for 7LF6111 timer in 4-wire circuit,
L-momentary, resettable
Usual circuit for new installation with separate cable routing for
pushbuttons and lights. The additional DI switch allows external
switching to continuous light or a time switch can also be used
for this purpose. An additional attic circuit is also available,
which operates independently of the timer, but on the same
electrical circuit. The timer can be restarted before the set time
expires.
te = Runtime
Typical circuit for 7LF6111 timer in 3-wire circuit,
N-momentary, resettable
Can only be used with a limited number of wires. The timer can
be restarted before the set time expires. While this 3-wire circuit
with N-momentary contact is technically possible, it does not
comply with DIN VDE 0100-460. However, it is used in legacy
systems for replacement purposes.
te = Runtime
Typical circuit for 7LF6112 timer for fans up to 200 VA
The switch switches the light on immediately, e.g. in a toilet. After
a delay of approx. 1 minute, the fan is switched on. When the
light is switched off, the fan continues to run for the time set at
the timer.
te = Runtime
Typical circuit for 7LF6115 energy-saving timer with advance
warning
The timer is connected in the same way as the 7LF6111 timer in
a 4-wire or 3-wire circuit. The energy-saving timer switches on if
pressed once and switches off when it is pressed again. If it is
not switched off manually, it is automatically switched off after
the set time, max. 60 minutes. 20 and 40 seconds before expiry,
the light flashes briefly twice (50 ms) to warn of the impending
tripping. This allows time to reset the switch while the light is still
on. Prior to the warning time, a push of the button ends the timing
interval.

7LF, 5TT3 Timers
Typical circuit for 7LF6116 energy-saving timer
The timer is connected in the same way as the 7LF6115 timer in
a 4-wire or 3-wire circuit. The energy-saving timer switches on if
pressed once and switches off when it is pressed again briefly
(less than 1 second).
Resetting is possible by pressing a second time for longer
(more than 1 second). If it is not switched off manually, it is
automatically switched off after the set time, max. 60 minutes.
te = Runtime
Lighting in ancillary rooms and corridors
In rooms subject to less frequent use (basements, ironing rooms,
attics, heating oil storerooms) there is a risk of the lighting re-
maining on unnecessarily for lengthy periods. In such cases, the
7LF6115 and 7LF6116 energy-saving timers can considerably
reduce energy costs while increasing user-friendliness.
Occupants leaving a room can switch off the light by push-
button, just like an installation with remote control switch. In the
event that occupants are unable to switch the light off, or simply
forget, it will go out automatically after a pre-set time.
The 7LF6115 and 7LF6116 energy-saving timers can also be
used in corridors, e.g. as replacements for remote control
switches. In this case they combine the familiar functionality of a
remote control switch with the energy-saving features of a
stairwell lighting timer.
Typical circuit for 7LF6110 timer in 3-wire circuit,
L-momentary contact, not resettable
Circuit for new installation with shared cable routing for push-
buttons and lights. The timer can only be restarted after the set
time expires.
te = Runtime
Typical circuit for 7LF6113 energy-saving timer with advance
warning
The timer is connected in the same way as the 7LF6111 timer in
a 4-wire or 3-wire circuit. 20 and 40 seconds before expiry, the
light flashes briefly twice (50 ms) to warn of the impending
tripping. This allows time to reset the switch while the light is
still on.
te = Runtime
Typical circuit for 7LF6114 energy-saving timer with advance
warning
The timer is connected in the same way as the 7LF6111 timer in
a 4-wire or 3-wire circuit. When pressed, the lighting timer
switches on for the set runtime, up to 10 minutes. If the switch is
pressed for more than one second, the light is switched on for
four times the set time, i.e. up to 40 minutes. The last press of the
pushbutton is definitive. 20 and 40 seconds before expiry, the
light flashes briefly twice (50 ms) to warn of the impending
tripping. This allows time to reset the switch while the light is still
on. The timing interval restarts each time the button is pressed.

Typical circuit for 5TT1303 ECG control switch
The device is fitted with a direct voltage input for the control of
an ECG. When the pushbutton is actuated, the power supply is
released and the ECG is brightened for up to 10 minutes,
depending on the setting of the timer.
On expiry of this time, the ECG is dimmed according to the set
dimmer level, if pressed again it brightens again. If no requests
are made for 30 minutes (no buttons pressed), the lighting is fully
deactivated. In addition to these functions, the dimming time
and brightness period can also be controlled using a separate
pushbutton or time switch over the control inputs B1 and B2.
Switching the ECG and the fluorescent lamp as little as possible
extends the service life.
Hall lighting in nursing homes
At meal times, from 5 to 7 p.m., the light in the corridors can be
permanently switched on using a time switch (contact B1).
Between 7 p.m. and 10 p.m., the lighting is dimmed using
switch B2. Simply press the corridor pushbutton again to return
the lighting to the bright setting at any time. After 10 p.m., the
light is switched off. It can be switched back on at any time by
pressing the corridor pushbutton.
Corridor lighting in hospitals
During the day – i.e. during peak periods, lunch times, visiting
times, shift changes, doctor's rounds – the light is switched on.
During quiet periods, i.e. afternoons and nights, the light is
switched to a dimmed state. A patient can switch the light back
to the bright setting at any time by pressing the corridor
pushbutton. In emergencies, the nurse can use a B1 switch to
switch to "emergency operation", i.e. permanently bright (no time
limit of brightness period).

More information
Stairwell lighting
This is required in DIN 18015-2 "Electrical installations in
residential buildings; Nature and extent of minimum equipment".
What is less known is that 100 lux is required according to
EN 12464-1 "Lighting of work places" for interior areas and
corridors, section 5.3. This means that approx. 60 W
incandescent lamps, 25 W energy-saving lamps or 25 W
fluorescent lamps need to be used. It is hard to see why lower
requirements should apply to stairwells in residential buildings
than stipulated in EN 12464-1.
4-wire circuit, L-momentary contact
4 wires are installed within the building. The timing interval is
started by pressing phase L. During the runtime, the timer can
be reset at all times.
3-wire circuit, L-momentary contact
3 wires are installed within the building. The timing interval is
started by pressing phase L. No resetting is possible during the
runtime as the pushbutton input and output are exposed to the
same potential during this period. The glow lamps are switched
off during the runtime.
3-wire circuit, N-momentary contact
3 wires are installed within the building. The timing interval is
started by pressing the N conductor. During the runtime, the
timer can be reset at all times. However, this switching no longer
corresponds to DIN VDE 0100 and is now only used in legacy
systems.
Safety through warning prior to switch-off
DIN 18015-2 "Electrical installations in residential buildings:
Nature and extent of minimum equipment" stipulates that the
automatic lighting-off control in stairwells of appartment blocks
must be equipped with a warning function to prevent sudden
darkness in the building. This contribution towards safety is
offered by 4 device versions. The 7LF6113 stairwell lighting
timer, the 7LF6114 lighting timer and the 7LF6115 energy-saving
timer warn of an impending switch-off by flashing, the 5TT1303
stairwell lighting timer ECG warns of an impending switch-off by
dimming, allowing sufficient time for the light switch to be
pressed again.
Manual switches
All timers have a manual switch for the function "Automatic/ON".
This allows the operator to switch to continuous light in the event
of moving house or emergencies.
Useful continuous contact
Pushbuttons should never jam. For this reason, all our timers
have a safeguard to prevent this type of malfunction. Even
better, this feature can be used (e.g. by caretakers of properties)
to switch to a continuous light in the event of moving house or
emergencies.
Setting accuracy
The electronic remote control switches offer a high degree of
accuracy. The runtime can be set precisely to +30 seconds
using the push-to-lock knurling wheel setting. The factory
settings ensure that the limit values of 1 and 10 or 60 minutes
can be reliably set.
Short-circuit strength
Stairwell lighting timers are primarily used for the switching of
incandescent lamps, which may occasionally be subject to short
circuits. A key feature of all devices is their high short-circuit
strength without the contacts welding.
Switching of fluorescent lamps
In order to extend their service life as far as possible, fluorescent
lamps should only be switched using a stairwell lighting timer if
the switching frequency is not excessive. Using electronic
ballast (ECG) to operate them is more gentle on the device and
saves energy. The 5TT1303 stairwell lighting timer ECG switches
the electronic ballast and warns of the impending switch-off by
dimming.
Switching of energy-saving lamps
The switching of energy-saving lamps depends greatly on the
lamp type used. Standard energy-saving lamps are generally
unsuitable for warning by flashing or dimming prior to switch-off.
The 7LF6110 and 7LF6111 stairwell timers and the 7LF6116
energy-saving timers without warning of impending switch-off
are suitable for the use of standard energy-saving lamps
(e.g. OSRAM DULUX EL).
For applications with warning of impending switch-off (7LF6113
and 7LF6114 stairwell lighting timers or 7LF6115 energy-saving
timers) we recommend the use of special energy-saving lamps
such as OSRAM DULUX EL FACILITY or OSRAM DULUX

Setting aids
The period of the flashing of the green LED 1 when set for a
timing interval is 1 s 4 %, and can therefore be used as a
setting aid. This is particularly useful in the lower time setting
range and for long delay times because of the accuracy of the
multiplication factors between the individual time ranges.
Example:
Delay time to be set: 40 min.
Using the fine setting, this delay time can be set within the
setting range 3 ... 300 min. However, in this case it takes a long
time to check the time and requires several operational
sequences in realtime. To speed up the setting process, the
setting range is switched to 0.03 ... 3 min. In this case, the
required value corresponds to a delay time 0.4 min (= 24 s). The
timing interval is triggered and the potentiometer is set to
24 flashing periods of the yellow LED 2. The device is then set
back to the setting range 3 ... 300 min and the setting process is
completed.
Time operation interruption/time addition
For the functions AV, EW, IE, BI, the timing interval can be
interrupted at any time by activating B1 (+) and continued again
by removing the control voltage (time addition).
Control input B1
The functions RV, IF, AW, AV/RV can be controlled using the
control input B1 (+) with potential against terminal A2. The
auxiliary voltage of terminal A1 – or any other voltage within the
range 12 ... 240 V AC/DC – can be used for this purpose. The
operation of parallel loads (e.g. contactors) from B1 (+) to A2 is
also permissible.
If voltage is simultaneously applied to the control input B1 (+)
and A1 for the IF function, this triggers an output pulse with the
set time interval t1.
