Important safety instructions
VISATEC flash light systems should exclusively be utilised for professional
flash light systems by qualified personnel. Before starting up your flash
light equipment read carefully all the information in your operating
instruction. The safety instructions in the operating instructions must be
imperatively followed!
• Read and understand all instructions before using!
• Remove the transport protection and the packing material
• Close supervision is necessary when any appliance is used near children. Do not
leave the flash light appliance unattended while in use!
• Flash light contains, similar to sunlight, a specific portion of UV radiation! The
undesirable side effects on skin and eyes are considerably reduced by using flash
tubes or protecting glasses with UV safety measures! Nevertheless, taking pictures at
close distances with unprotected skin and eyes should be avoided! Also avoid eye
contact with the light source! The maximum daily UV radiation according to IEC
60335-2-27 / DIN 5031-10 is: 50 J/m2. This value should not be exceeded!
• With due allowance for heat radiation, the distance between the monolight and a
person or between the monolight and inflammable respectively heat sensitive
surfaces should be at a minimum distance of 1 m!
• Prior to replacing flash tubes, halogen lamps, protecting glasses or fuses, disconnect
the monolight and the lamp from the power supply! Prior to replacing the halogen
lamp or the flash tube, the monolight should cool down for 10 min.!
• VISATEC flash light systems should only be equipped with original VISATEC flash
tubes, original VISATEC combustible and packing material, original VISATEC
accessories, and also original VISATEC spare parts!
• VISATEC flash light systems, lamps and accessories meet an extremely high safety
standard! When connecting VISATEC units to accessories of other brands, integrated
safety measures may become ineffective! Due to different design features and
contact assignment of the products of other brands, the user himself/herself may
even be at risk. We offer no guarantee and accept no liability for damages which may
be caused by this type of usage!
• To avoid the risk of fire, electric shock or injury to persons utilise exclusively the
accessory recommended by the manufacturer!
• Check that the mains voltage corresponds to the information on the type plate of the
unit!
• The flash light equipment is designed for use in dry conditions and in an ambient
temperature from 0°C to 35°C! The flash light equipment has to be protected from
wetness, condensation, from dripping and splash water, humidity, dirt, sand, metal
chips and exposure to dust!
• Protect the flash light equipment from electromagnetic fields, shock and vibration!
• Protect the flash light equipment from heat and frost! If the monolight freezes
continuous loss of power output and serious technical damage can result!

- 3 -
• Sudden temperature differences can cause condensation water in the unit! In such
situations the equipment must stay for 1 hour in a well ventilated place to get
acclimatise to the new temperature before startup!
• Do not operate the units in an environment where there is a risk of explosion!
• The monolight should not be operated in or near water! Attention: high voltage!
• The monolight and the lamps should not be immersed in water or other liquids! It
could cause an electric shock!
• Remove the transport protection cap on the front side of the monolight before
connecting it!
• For safety reasons, never operate the monolight without the protecting glass in place!
UV-coated protecting glasses or UV-coated flash tubes must be utilised as a
protection against UV radiation for eyes and skin!
• Before operation the monolight has to be fastened on a stand or a suspension device!
The monolight must be locked by tightening the mounting screw!
• Only sand-filled fuses of the type indicated on the safety type plate may be used with
these monolight, as a protection for the halogen lamp! Sand-filled fuses can be
identified by their opaque fuse body! With incorrect fuse protection the halogen lamp
may burst!
• Filters or diffusors should not be fastened directly on the flash tube, halogen
modelling lamp or protecting glass!
• Do not operate appliance with a damaged earthed cable. Cables which are damaged
or twisted must be replaced!
• The unit must only be connected to an earthed socket, or an emergency power
generator and an earthed extension cable!
• If an extension cable is necessary, a cable with a current rating at least equal to that
of the appliance should be used. Cables rated for less amperage than the appliance
may overheat. When using a cable reel, it must be completely unrolled before use to
prevent overheating of the cable!
• The unit is suitable for operation with a motor generator provided that the voltage lies
within all the load conditions (including capacitive load) and within the tolerance limit
of 200-264 V respectively 95-135 V! From experience this means that only electronic
stabilised motor generators are to be utilised! When operating on unstabilised motor
generators, voltage peaks of 300 V and more have been observed! This can lead to
damages for which we assume no liability!
• Do not operate the lamps inside a bag or a box!
• The ventilation slots on the unit or on the lamp should not be covered!
• Pay attention when laying, clearing away or rolling up cables that the do not contact
hot surfaces or parts of lamps and that they will not be tripped over by persons!
• Do not touch the connection socket for mains cable and lamp outlets on the
monolight and do not poke in it with metal objects!
• Flash tubes, modelling light, halogen lamps and protecting glasses heat up to a high
operating temperature, this also applies to the front side of the monolight! Therefore
the attachments also assume also temperatures! Handle with care! Contact with hot
components can cause injuries!

- 4 -
• Do not come into contact with glass or metal whilst operating the flash light system!
• Let the unit cool completely after use and before packing!
• Always unplug appliance from electrical socket before cleaning and servicing and
when not in use! Never jerk cable to pull the plug from the socket. Grasp plug and pull
to disconnect!
• Dropped or damaged units or lamps must be checked by a specialist before
reconnection!

1. Application LOGOS
This mains supplied studio flash is designed for professional photography. For your own
safety, use a three-wire extension cable when required.
2. Start up
2.1 Mains voltage
The monolights LOGOS 800 and LOGOS 1600 are available in two different versions:
a) As a bi-voltage unit, of which the technical data are optimised for a mains voltage of
200 - 240 V. If this version is operated with a mains voltage of 100 – 120 V, a doubling
of the charging time results.
b) As an unit, which is exclusively designed for mains voltage of 100 - 120 V.
2.2 Earthed mains
Connect unit to current supply always using an earthed mains plug.
2.3 Start up
Flash tubes, modelling light, halogen lamps and protecting glasses heat up to a high
operating temperature! This also applies to the front side of the monolight! Therefore the
attachments also assume also temperatures! Handle with care! Contact with hot
components can cause injuries! For this reason, we recommend to touch the unit only on
the handle at the rear or on the stand adapter. The distance between the monolight and a
person or between the monolight and inflammable respectively heat sensitive surfaces
should be at a minimum distance of 1 m!
1.) Remove the grey plastic protecting cap by turning and releasing the unlocking slide at the
same time. Insert modelling lamp and flash tube as per instructions in chapter 8. Put on
the protecting glass as well as the desired light shaper and turn in any direction.
2.) Please check that the mains supply corresponds to the information on the label of the
unit. Connect unit to earthed mains.
3.) Switch on the unit with the mains switch (9). During charging, the digital flash energy
display (10) flashes, afterwards the value is indicated continuously. Additionally the green
control lamp of the ready display (5) is illuminated.
4.) Set the desired flash energy by means of the energy control keys “up / down“ (8).
5.) Switch photocell (17) on or off, depending on the exposure situation.
6.) If required, plug in synchronous cable in one of the sync sockets (1) or (2).

- 8 -
3. Energy control
Use the "up / down" keys (8) to control the flash energy (flash intensity) within a range of
4 f-stops. A value of 10 indicates maximum intensity, 6 the minimum. Whole numbers
correspond to whole f-stop intervals, decimal places to tenth f-stop steps.
Brief pressure on the energy control keys "up / down" (8) changes the setting by a 1/10
interval, prolonged pressure by 1/1 f-stop interval. The energy display (10) then flashes
until charging or discharging have stabilized the new level of energy.
4. Modelling light
4.1 General
The LOGOS compact units are equipped with a very bright 150 W halogen modelling
lamp. The modelling light is switched on by the key "mod" (4). When switched on, the
green diode lights up.
In chapter 7 you can find the instructions how to set the different operating modes
(modelling light proportionality).
Attention: Please note, the voltage of the modelling lamp must correspond with the
mains voltage.
4.2 Proportionality
The brightness of the modelling light can be set proportionally to the flash intensity. To
assure proportionality also when units with different power output ratings are operated
together, the units have various proportionality levels. Proportionality is guaranteed if the
identical prop level has been set for all units. The higher the digit, the brighter the
modelling light. The proportionality levels of the LOGOS monolights are compatible with
those of the broncolor units.
The following operating modes are possible:
“P“ This level can be set if either only LOGOS 800 or only LOGOS 1600 are in use
(most intense proportional modelling light). That means, the modelling light is
proportional to the energy level 300J respectively 600J.
“P1“ weak proportional modelling light, applicable for all types of units
“P2“ recommended modelling light when using LOGOS 1600 (also in combination with
LOGOS 800)
“P3“ recommended modelling light when using only LOGOS 800
“P4/5“ If an unit is operated at a lower output level, the modelling light will be relatively
weak and yellowish. To counteract this problem, the LOGOS monolights are
equipped with two additional modelling light proportionality levels: “P4“ for 150 J

- 9 -
or less and “P5“ for 75 J or less. Thus the brightness of the modelling light can be
increased.
“HI“ The unit operates at full modelling light, independent of flash output.
“LO“ The unit operates at lower lighting level, independent of flash output, to reduce
power consumption and extend the service life of the halogen lamps.
Pressing the “mod“ key (4) for 1 second when the modelling light is on, will give direct
access to the “HI“ mode. To return to the previous mode briefly press the “mod“ key.
The halogen lamp can be plugged in; when exchanging, do not touch the lamp with bare
hands. Please note that the flash tube must be pulled out before exchanging the halogen
lamp.
4.3 Replacing halogen lamps
Attention: Prior to each exchange of the halogen lamp, the monolight must be fired
down and immediately afterwards disconnected from the mains! Before
exchanging the modelling lamp let the monolight discharge and cool down
for 10 min.! For your safety, only original flash tubes must be used!
The halogen lamps are plug-in.
To change the halogen lamp, pull the protecting glass straight along the lamp axis,
without tilting. Afterwards pull the flash tube straight along the lamp axis, so that the
halogen lamp can be replaced. Taking the service life into consideration, the halogen
lamp should not be handled with bare hands.To change the lamp, pull it also straight
along the lamp axis.
When inserting be sure that the halogen lamp and the flash tube are fully pushed in.
Then the protecting glass must be mounted.
5. Release
The flash release is enabled when 85 % of the selected energy is available. Please note,
however, that the ready indicator is activated only at 100 % charge (chapter 6). The
release is possible by means of a sync cable, photocell or the manual release key.
5.1 Photocell (cell)
The photocell can be switched on or off by using the “cell“ key (3). If it is activated the
green LED lights up. After a flash sequence, an active photocell will be blocked and the
green LED blinks. By pressing the "cell" key, the photocell is reactivated.
When releasing via the photocell, ensure that the receiving cell of the unit it not
obstructed by obstacles.
Because the photocell is also infrared-sensitive, the monolight can be wirelessly released
in a simple way by using a small flash unit with an infrared-permeable filter in front,
mounted onto the camera. The VISATEC flash trigger is available under article number
56.200.00.

- 10 -
5.2 Sync sockets
The synchronous cable, art. no. 54.104.00, may be plugged into the sync sockets (1) or
(2) to release flashes via cable.
The appliance has a synchronous circuit with a low onload voltage to preserve your
camera contact. The synchronous circuit may not be connected in parallel with products
of other manufacturers which operate with high synchronous voltage.
5.3 “Test“key
This “test“ key (5) allows manual release of the monolight LOGOS. The respective LED
lights up, when the flash voltage corresponds exactly to the selected value. During
charging and discharging, the LED goes out and the output display blinks.
6. Ready display visual / audible
6.1 The visual ready display is the green LED at the “test“ key (5). It lights up only when the
unit is at 100 % charge. After releasing the flash, this LED goes out until the unit is fully
charged again.
6.2 The audible ready signal "buzzer" sounds when the unit is at 100 % charge. It may be
switched on or off (chapter 7).
6.3 Audible fault signal
When the flash discharge fails, a warning signal of approx. 3 s duration will sound and
the display (10) of the monolight will flash.
7. Setting additional functions
The “aux“ key (11) is used to set the additional functions. With repeated actuation of the
key the following modes can be selected:
• Setting proportionality level of the modelling light LED “prop“ blinks (12)
• Define sequence (serial flashes) LED “seq“ blinks (13)
• Charging dimmer switch on / off LED “dim“ blinks (14)
• Buzzer switch on / off LED “buz“ blinks (15)
• Slow charge switch on / off LED “slow“ blinks (16)
• Setting appliance address / studio address LED “unit“ blinks (18)
• Return to standard display no LED blinks
After the setting has been performed, the standard display can be re-activated by
pressing the “aux“ key (11) or automatically after a waiting period of approx. 30 seconds.

- 11 -
To select the additional functions and appliance settings, choose the respective LED (eg
“charging dimmer switch on / off“). The digital display (10) will then show the actual
selected value which can be changed by the energy control keys “up / down“ (8). If a
setting is entered which deviates from the standard setting value or a function is
activated, the respective LED will remain lit as a reminder after the display returns to
standard (exception: functions “prop“ and “unit“).
If the unit is switched off and on again, it will be in the “standard display“ mode.
Previously set additional functions are retained.
7.1 Setting proportionality level of the modelling light (prop)
The proportionality level of the modelling light can be selected by briefly pressing the
energy control keys “up / down“ (8). With repeated actuation of the key the following
modes can be set, each shown respectively on the digital display (10): P, P1, P2, P3, P4,
P5, HI, LO.
7.2 Sequence (serial flashes) (seq)
This function allows to set a defined number of flash discharges from 1 to 50. By briefly
pressing the energy control keys “up / down“ (8), the required number of flashes can be
selected. With a long pressure on the energy control keys “up / down“ (8), the setting
changes in intervals of ten. Each release signal triggers the selected number of flashes.
A current sequence can be aborted by a long pressure on the energy control keys “up /
down“ (8) or by switching off and on again the unit.
7.3 Charging dimmer / boost function (dim)
The “dim“ function can be switched on or off (on/--) by briefly pressing the energy control
keys “up / down“ (8). When switching on the “dim“ function with the modelling light on
(green LED of the “mod“ key (4) lights up), the modelling light switches off while charging
takes place. This feature allows visual flash control, to fade out the modelling light during
flash sequences or to reduce the current load on weak mains.
If the “dim“ function is activated when the modelling light is switched off (green LED of
the “mod“ key (4) is off), the boost function will be activated. In this mode, the modelling
light remains on as a visual flash monitor during charging.
7.4 Buzzer switch on / off (buz)
The ready buzzer signals when the unit is at 100 % charge. The buzzer is switched on or
off (on/--) by briefly pressing the energy control keys “up / down“ (8). The warning signal
also functions with the buzzer switched off.
7.5 Slow charge switch on / off (slow)
In case of weak mains power supply lines, charging time may be extended to approx.
double the standard value. The slow charge mode is switched on or off (on/--) by briefly
pressing the energy control keys “up / down“ (8).

- 12 -
7.6 Studio / appliance address (unit)
The monolights LOGOS are also available as versions with built-in RFS Interface (Radio
Frequency System). For remote control respectively flash release via radio, an individual
appliance address and a studio desk top (remote control channel) can be assigned to
each RFS unit by means of the function “unit“ (18).
To carry out the settings, dial the LED “unit“ using the “aux“ key (11). The digital display
(10) shows the letter “U“, followed by an appliance number between 1 and 8. By briefly
pressing the energy control keys “up / down“ (8), the required value can be selected.
When pressing again the “aux“ key (11), the digital display (10) shows the letter “C“,
followed by a studio number between 1 and 8. By briefly pressing the energy control keys
“up / down“ (8), the required value can be selected.
8. Flash tube
The flash tube is coated to ensure an optimal colour temperature. For your security, only
original VISATEC flash tubes must be used. For safety reasons, never operate a unit
without protecting glass in place.
If the monolight LOGOS 800 is used for longer flash sequences, we recommend to
employ the flash tube for LOGOS 1600 / SOLO 1600B - Art. no. 54.301.00.
8.1 Replacing the flash tube
Attention: Prior to each exchange of the flash tube, the monolight must be fired
down and immediately afterwards disconnected from the mains! Before
exchanging the flash tube, let the monolight discharge and cool down for 10
min.!
The flash tubes are plug-in.
1.) To replace the flash tube, discharge the unit by flashes, disconnect it from power
supply and let it cool off for ten minutes (to discharge the flash capacitors).
2.) Remove the protecting glass.
3.) First pull out the ignition cable and then the flash tube (do not touch the flash tube
with bare hands).
4.) Insert the new flash tube.
5.) Re-insert the ignition cable.
6.) Replace the protecting glass.
7.) Connect the unit to the power supply, now it is ready for use again.

- 13 -
9. Protecting glass
For your security, only original VISATEC protecting glasses must be used!
For safety reasons, never operate the monolight without protecting glass in place.
10. Fuse
The fuse (7) is located on the rear of the unit. Sand-filled fuses with value 3.15 AF may
only be used (sand-filled fuses can be identified by their opaque fuse container). Using
wrong fuses is dangerous; it may cause the halogen lamp to burst. Original VISATEC
replacement lamps are therefore delivered with the correct fuse.
11. Basic settings ex work
The basic settings ex work can be viewed and in some instances changed with the
following procedure:
When the unit is switched on, simultaneously press the "mod" and "aux" keys for
approx. 5 seconds (the LED array "prop" / “seq“ / "dim" / "buz" / “slow“ / "unit" blinks to
indicate that you are in the programming mode).
Additionally the LED of the “mod“ key is lit. The digital display shows the function
number 0. The other function numbers can be selected by pressing the energy control
keys “up / down“ (8).
By briefly pressing the “aux“ key, the digital display shows the actual value respectively
the actual setting within the selected function number. The LED of the “mod“ key does
not light up in this mode. Within the function numbers 1 and 7, the settings can be
changed with the energy control keys “up / down“ (8). Concerning the function numbers
0 and 2 – 6, the different pairs of these multiple digit values can be shown by means of
the energy control keys “up / down“ (8).
Return to normal operation by pressing (1 s) the “aux“ key, by switching the unit off and
on again or automatically after a period of 20 seconds.

6 Production date of the unit: Figure group in the display: XXxx = year
7 Reduction of the modelling light: Setting ex works: "off" (--)
The activation of this function is recommended on power mains with
great fluctuations. The voltage for the modelling lamp is reduced (light
output ./. 1/3 f-stop), which results in a longer service life of the
halogen lamp. If this function is activated, the digital display shows the
value “on“.
12. Protective facilities / Fault indication
12.1 Cooling fan
The cooling of flash tube, modelling lamp and internal electronics is effected by a cooling
fan. It also runs when the modelling light is turned off. The cooling works on two levels,
the fan runs smoothly when small flash sequences are effected. With longer flash
sequences, the cooling fan switches to the higher level.
12.2 Display “th“
If excessively high temperatures build up inside despite the fan cooling, the charge mode
will be blocked and a long audible signal will be generated. The modelling light is blocked
as well for about 6 minutes. The digital display shows the indication "th" during the
cooling period. The cooling process is accelerated by the fan which is still in operation.
Attention: Do not switch off the unit during the cooling period! If the unit is
switched off too early, only a small number of flashes can be effected until
the next blockout, when switching on again the unit, despite a long break,
because the processor could not completely pursue the cooling process.

- 15 -
12.3 Display “A1“
The unit is equipped with an automatic afterglow blockout. If the flash tube exhibits (e.g.
at the end of its service life) afterglow, this blockout will block further charging to prevent
consequential damage. This status is also discernible by the ready display, which is no
longer green. The blockout can be cancelled by switching the unit off and on again.
12.4 Display “A2“
This indication is shown, when the unit is overcharging. Switch off the unit and switch it
on again after a few minutes. If this fault continues to exist, please contact an after-sales
service centre.
12.5 Acoustic flash monitoring
At the end of their service life, flash tubes often have triggering interruptions. This fault is
indicated by an audible, intermittent signal. The signal disappears when the flash tube
flashes properly again or the unit is switched off.
12.6 Monitoring of the modelling light
If the monolights LOGOS are connected to 200 V – 240 V mains voltage, after previously
having been operated on 100 V - 120 V mains voltage, they will release an audible signal
and the modelling light will blink at a safely reduced voltage. This function serves as a
reminder that the modelling lamp must be exchanged, and also to protect against
damage of the lamp. Switch the unit off and on again to return to standard operation.
13. Mounting
The stand adapter is located below the housing. The adapter is designed for standard
broncolor® bolts (12 mm) and Manfrotto®pins (16 mm). Make sure the unit is firmly
attached to the stand before operating. The click-stops of the locking handle can be
adjusted by pulling it out.
If the unit should be suspended without bracket on a broncolor®bolt, the enclosed
locking pin must be screwed into the lower part of the stand adapter. This is not required
for stand mounting.
Attention: A safety cable must be installed whenever the unit is suspended.

- 16 -
14. Umbrella holder
Diffusing and reflex umbrellas are used in conjunction with the umbrella reflector (art. no.
53.457.00). The umbrella bar is inserted into the special holder in the stand adapter.
15. Accessories
The monolight LOGOS is equipped with an interlocking VISATEC bajonet, which permits
a 360° rotation of the mounted light shapers. For this reason, the whole range of
VISATEC accessories assortment is at your disposal. You will find the complete overall
view in the VISATEC system catalogue.
15.1 Mounting of barn doors
The barn doors are attached onto the fastening braces on the reflector.
16. Service / repair
Your VISATEC monolight is a precision device which will work for many years without
malfunction if you take proper care of it. If nevertheless malfunctions do arise, please do
not attempt to open the unit to repair it yourself. Even when the unit is switched off,
dangerous voltages may remain within the interior of the device. Always leave service
and repairs to the VISATEC after-sales service.

18. VISATEC LOGOS RFS / LOGOS plus
The monolights LOGOS are also available as unit versions with integrated 8 channel
RFS Interface (Radio Frequency System). Each channel (studio) can control up to 8
units. This interface allows remote control respectively flash release by radio via
transmitter RFS as well as by means of a transceiver RFS via PC or Macintosh
computer. When controlling via screen, 4 storage spaces for different lighting situations
are at your disposal.
18.1 Modification to LOGOS RFS
There is the possibility, to modify LOGOS monolights later on with a RFS interface. The
modification will be made by the customer service centre of our VISATEC agency in your
country.
18.2 LOGOS plus
Because of the laws in some countries, the use of the VISATEC radio system is not
allowed. Therefore the LOGOS monolights are also available in the version LOGOS Plus
(that means with cable remote control). Besides the cable connection between the
monolight and the computer, the applications with RFS is almost identical.
Attention: There is no camera transmitter available for LOGOS plus!
