Hedler DF15 User manual

Thank you for choosing a Hedler light unit and your
con dence in the Hedler light system. Please, read
the following technical informations carefully
before using the light unit.
Codes are given in <Brackets>.
TECHNICAL DESCRIPTION
Light units of the HEDLER DF range are designed for professional use, they are assembled by applying precision methods and tested individually
for function and quality. The focusable daylight HEDLER DF15 is provided with an integrated U-bracket and a friction brake and a 5/8” Quick-
Lock light stand attachment. After loosening the hex key screws by approx. 2 turns, the U-bracket can be moved back and forth in its keyway
for gravity adjustment and it is turnable for right and left hand use.
The focusable daylight HEDLER DF15 uses AC of 230 - 250 V and the modern metal halide 150 W SE T bulbs, which can be re-ignited after 2 - 3
minutes while the cooling down has started by switching-off the light unit. As a special feature, the HEDLER DF15 does not have a fan, which
means it suits ideal for original sound recording.
On its front side, the aluminium housing holds the Fresnel lens with its protective grid. AdditionalIy there are the Uni-Adapt studs and the
QuickFit adapter for attaching re ectors. Interchangeable re ectors with bayonet ring can be attached in the following way: place the rim of the
ring into the guide grooves of the upper studs and the round opening over the cone-shaped bolt, and lock it by a turn to the left. To attach the
rotatable 4-Leaf barndoors or a MaxiSoft folding re ector, place the rim of the ring into the guide grooves of the upper studs, and then push
the complete re ector towards the QuickFit´s cone-shaped bolt until the ring locks in the bolt´s groove. Detach the re ector by lifting the
QuickFit´s handle, moving the lower side of the re ector away from the light unit´s housing, and then lifting the re ector´s ring out of the guide
grooves of the upper studs.
On the opposite side of the housing, one will  nd the ergonomically incorporated handgrip, the cable and the main switch. Additionally you will
 nd on the backside of the housing the focusing turning knob, which allows to adjust precisely and intuitively the size of the light beam from
spot- to  oodlight setting.
In addition to the parabolic re ector, bulb socket and ignitor, the housing accomodates the electronic ballast, which supplies stabilized voltage to
the bulb, ensures  icker-free light of constant intensity and a colour temperature of app. 6000 K. Besides that, it will extend the average bulb life
by app. 20 percent and reduce the power consumption by about 12 percent. Ignition is effected by 1 x 5 KV symmetrically, faulty bulbs will be
detected and switched off automatically. RF interference reduction meets all applicable EN 61000-3-2 standards.

BULBS
To replace the bulb: please, make sure that the housing and the bulb of the DF15 has off before interchanging the bulb, otherwise there is a risk
of burning! Always disconnect the DF15 from the power supply before interchanging the bulb. Unscrew the socket screw of the cover plate
guard. The cover plate guard is located on the housings upper side, its socket screw is located at the  ange which faces towards the housings
backside. To unscrew the socket screw, use the socket wrench which was delivered with the DF15. After loosening the socket screw completely
remove the cover plate guard.
Turn the focusing knob until the DF15 has its maximum spot light position. Pull the defective bulb out of the socket, after doing so push the new
bulb carefully into the socket, oberving instructions by the bulb manufacturer.
After pushing the bulb into its socket, replace the cover plate guard. Make sure that its lug is located correctly into the housings notch. Afterwards
install the socket screw into the hosuings thread and tighten it hand-tight. Please, before taking the HEDLER DF15 in operation, make sure that
the cover plate guard is mounted correctly!
FRESNEL LENS
To replace the Fresnel lens: please, make sure that the housing of the DF15 has cooled off before interchanging the Fresnel lens, otherwise there
is a risk of burning! Always disconnect the DF15 from the power supply before interchanging the Fresnel lens. Unscrew the four socket screws
of the housings front plate and remove the front plate with the Fresnel lens. Unscrew the securing screws of the Fresnel lens and replace the
defective one with an original Hedler Fresnel lens only. After replacing the Fresnel lens tighten its securing screws hand-tight. Attach the front
plate at the housing and tighten the front plates four securing screws. Please, before taking the HEDLER DF15 in operation, make sure that the
front plate is mounted correctly!
FOCUSING the HEDLER DF15
To focus the HEDLER DF15s light beam turn the focusing knob anti clock-wise (increased  oodlight characteristic) or clock-wise (increased
spotlight characteristic) to adjust the light beams size.
ACCESSORIES
It is recommended to use light units of the Hedler range only in combination with an original HEDLER 4-Leaf barndoor or one of the HEDLER
accessory re ectors. This permits adjusting the light beam to the requirements of any situation. In addition to the re ectors MaxiNorm, MaxiSun,
