EX-100A Monolight

INSTRUCTIONS

Thank you for your purchase of the Impact EX-100A Monolight. The
EX-100A Monolight is economical and lightweight, yet durable enough to
give you many years of trouble-free service and enjoyment. Please read
these operating instructions and safety precautions carefully before
operating this equipment.

Features

• Three-stop range – full power to 1/8 power, steplessly

• Buil t-in opt ical slave

• Modeling lamp can be set to proportional or full power

• Accepts Elinchrom-s tyle reectors and head accessories
(8-inch grid reector included)

• Tactile, “grippy” feel that resist s slipping, scratches, and shock damage

• Commonly available 1/8˝ mini-plug sync input

• Low 4.3V trigger voltage – safe for any camera’s circuitry

Power Requirements

This light comes in two models; one is designed for use with 110 /120 V AC power in the US
and the other for 220V AC power in Europe. Neither model can be used ou tside of its
nati ve power region. Both are supplied with a three-prong, grounded plug. Do not
attempt to defeat this safet y feature. If necessary, use only grounded extension cords
rated for six amps or greater.

Warning

There are no user-serviceable parts inside the unit. Only qualied service engineers
should access the inside of the case (Danger – high-vol tage parts inside). Avoid damage
to both the ashtube and modeling lamp. If the modeling lamp or ashtube become
cracked or damaged in any way, they should be replaced immediat ely. Do not use your
ash unit in an environment where moisture or ammable vapor is likely to come in
contact with the unit . Turn the power off and unplug the power cord when the unit is not
in use. Always remove the modeling lamp and replace the protective cap when
transporting the unit. Avoid s trong light falling onto the slave cell as it will prevent
efcient operation. If the uni t blows a fuse, a replacement fuse can be inser ted in the
pull-out compartment on the back of the unit . To ensure long life of the ash capacitors,
the ash unit should be powered up and red several times at least every t wo months .

All ima ges in this manua l are for illustrat ive purposes onl y. You r unit may differ s lightly from th e one pictured.

Preparing Your Monolight for Use

Mount on a stand

(1) Select a stand or support
system of suitable weight
and dimensions to ensure
stable operation of the unit.

Install Reector &
Modeling Lamp

(2) Remove the protective
cap by pressing in and
turning it coun ter­clockwise. Pull the cap of f
and set aside.

(3) Install the modeling
lamp by screwing it into the
threaded socket.

CAU TION: Do not touch the lamp with your bare hands. Oil residue from your ngers can
cause the surface of the lamp to heat unevenly and explode. Use white cotton gloves or a
clean cloth.

(4) Install the reector where t he protective cap was before. Align the two notches on
the re ector with the white guidelines on the ash unit, press the reector in and rotate
clockwise unt il it locks in place. Rotate the outer ring to secure the reector.

Note: Take care when tting or removing reectors or softboxes to not damage the
ashtube assembly. The ashtube is very delicate. Always switch off the unit and
disconnect the power before tting or changing lamps, ashtubes, reectors, or softboxes.

Power Supply

Plug the power cord into the back of the ash unit. Before plugging the power cord into
the wall socket, make cert ain that the power switch is set to the OF F (circle) posi tion.

Note: The EX-100A flash unit comes in two designs; one is designed for use with 110/120V
AC power in the US and the other for use with 220V AC power in Europe. Neither model can
be used outside of its native power region.

Power Switch

Turn the power swi tch to the ON (line) position.
The flash will sound a beep and then sound a
second beep indicating that ash power has been
reached and the unit is ready to re. The green
ready light will also be lit . We recommend
charging the flash unit for one hour prior to its
init ial use and after an ex tended period of
inactivit y (more than t wo weeks). If the unit is left
unused for a few mon ths, or the unit has been
used predominantly at low power settings, we
recommend that t he power be increased to t he
maximum and the unit lef t switched on (wi th the
modeling lamp OFF) for at least 30 minutes, with
several test ashes red, to help preserve the life
of the capacitors.

Flash Settings Changing the Fuse

Flash Output

The ash power output is variable over a three
f/stop range (f our f/stops) from full power to 1/8
power in a stepless gradation. Flash power is
adjus ted by rotating t he power-regulator knob on
the back panel of the unit. The EX-100A will sound
a beep and t he green indicator will light when the
unit has recycled and is ready to ash.

Lowering Flash Power

While raising the ash power requires no special
consideration, lowering the power does. Excess
power that has built up in the system’s capacitors
must be released. You must press the red test
but ton to manually “pop” the ash after a
power-lowering adjustment. T he EX-100A will
then recycle to the lower power you’ve selected.
A beep will sound and t he green indicator will
light when the unit has recycled and is ready to
ash again.

Caution: To avoid eye damage, do not look into the
strobe while ring. Do not re the ash in close
proximity to the face. Turn the unit off and unplug
the power cord when changing attachments.

Manually “pop” the ash when
reducing ash power. This will
ush the excess power in the
capacitors.
