Multiblitz XENOLUX 250 Instrucciones De Uso página 10

3. Assembly
The units have a mounting bracket (14) provi-
ded with a 5/8-inch socket (15) with clamp
screw (16). The socket accepts the 5/8-inch
studs of lighting stands. For stands with studs
of different diameter, use an MA-151 adapter.
After slackening the handwheel (4), the entire
flash head can be tilted up or down with grip
(1). To lock it in place, tighten handwheel (4).
4. Preparing the unit for operation
Fit halogen tube (see item 13 of these instruc-
tions). Carefully remove the tube from its sepa-
rate packing and insert it into the unit. Connect
the power cable to socket (26) at the bottom of
the unit and plug it into an AC wall outlet.
Switch the unit on using the red master switch
(8); the red LED above button (8) lights up.
Display (2) blinks while the capacitors are char-
ging. As soon as display (2) is permanently lit,
the unit is ready to fire.
5. Power supply
The units are factory-set for operation on
220-240 V / 50-60 Hz AC. Before connecting
for the first time, check to make sure that
you power supply coincides with the volta-
ge given on nameplate (25).
6. Switching on the modeling light
Once the unit has been switched on with the
red master switch (8), you may switch on the
halogen modeling light using the silver button
(7). The LED above the switch will light up red.
The brightness of the modeling light varies in
proportion to the flash output selected.
XENOLUX 250 and 500 come with a 150w /
250w halogen tube, XENOLUX 1000 and 1500
with a 650w halogen tube. These two types of
halogen tube are freely interchangeable in
XENOLUX 250, 500, and 1000 units.
7. Controlling output in 1/10 f-stops
Use knob (9) to vary flash output from approx.
6% to 100% (five f-stops can be set). The dis-
play (2) shows the output selected in 1/10
f-stop increments; reproducibility is ± 1%.
Flash and halogen light are controlled porpor-
tionally and have a fixed relationship. When
switching from high to low output, the excessi-
ve energy is dissipated internally, with the dis-
play (2) blinking during this period.
8. 100% modeling light
Button (5) serves to set the halogen light to full
power regardless of the flash output selected
with knob (9).
Halogen 100%: LED above button (5) lights up
red.

9. PROP. X focusing light
The total output of the halogen tube can be
reduced with switch (6). As a result, proportio-
nality of the focusing light is guaranteed within
the Xenolux system even when flash units of
different power are used.
Example:
Combined use of Xenolux 1500 and 1000.
Focusing light of Xenolux 1500: Full output of
650 W, switch (6) NOT depressed.
Focusing light of Xenolux 1000: Switch (6)
depressed, LED lights red, 650W halogen tube
has reduced output.
This guarantees proportionality even with flash
units of different power.
Switch (6) depressed, red LED lit – Reduced total
output of halogen tube.
The control range available through knob (9) re-
mains unchanged even in the reduced mode.
10. Visual and acoustic firing monitor
The unit offers visual and acoustical confirma-
tion of flash firing, which can be activated with
button (11).
Switch (11) depressed / LED above switch (11)
lights red:
After firing, the halogen modeling light will go
out and come on only when the unit has
recharged. In a multiple-flash setup it is there-
fore easy to check whether all units have fired.
Switch (11) in opposite position / LED above
switch (11) does NOT light: An acoustic signal
can be heard after recycling; the optical moni-
tor is deactivated.
11. Synchronization
Plug the sync cable into terminal (24) at the
bottom of the unit and connect it to the came-
ra. Further flash units are triggered via the sla-
ve cell (3) which also serves as an infrared
sensor. It can be switched on or off with but-
ton (12).
Slave cell ON: LED above button (12) lights up
red.
Switch (13) serves to reduce the sensitivity of
the photocell.
Switch (13) depressed, LED lights red = reduced
sensitivity.
This setting is useful, for example, near flickering
fluorescent tubes that might fire the flash units
uncontrollably.
Switch (13) released, LED NOT lit = high sensi-
tivity of photocell.
XENOLUX units come with a small white cap that
can be slipped onto the photocell if necessary to
shield the cell completely from external light.
12. Changing reflectors
All reflectors are attached by means of a stan-
