Assembly
Your spotlight can be suspended from a carrier bar by means
of a DIN/BBC spigot in accordance with the standards DIN
15560-101 (an accessory for the manually controlled model).
This spigot socket provided for the sections HB and HS of DIN
15560-102. It may also be mounted on a tripod (manual model).
These accessories are available as an option .
You should avoid placing the spotlight close to inflammable
materials; the minimum distance is shown on the index plate.
Do not exceed the maximum angles of inclination stated on the
index plate. ALWAYS use the safety cable by passing it into
the safety ring or into the suspension yoke.
Assembly of the accessories.
Consult the list of accessories.
The front door comprises two slides to receice the various
accessories; the first one (exterior) is provided for the 4-leaf
barndoor which is supplied with the spotlight; the second one
(interior) is provided for the colour filter frame or the diffusing
scrims. These various accessories are fixed to the spotlight by
two lateral channels and a channel inthe base of the door. A
retaining catch, situated on the upper part of the door, prevents
the accessories from accidentally falling during the manoeuvering
of the spotlight (see page 10).
Remark:
The weight of the accessories shall not be more than 25% of the
weight of the luminair.
4-leaf barndoor.
The 4-leaf barndoor, which is supplied with the spotlight, is
made up of four blades and of a metal ring.
In order to fit this, release the retaining catch by pulling it laterally
and pivoting it through 180°.
Insert the 4-leaf barndoor into its slide; check that it is properly
engaged into the three channels. Lock the retaining catch
again. The frictional force of each blade may be situated at each
end of the blade.
Metal or cardboard filter frame.
Cut out the colour filter and place it in the filter frame. Release
the retaining catch and insert the filter frame into the interior
slide; check that it is properly engaged into the three channels.
Lock the retaining catch again.
Metallic diffusing scrims.
ADB supplies two types of metal diffusing scrims : the square
scrim and the orientable half-moon scrim; each type is available
with attenuation of 25% or 50%. These accessories permit the
luminous intensity of the spotlight to be attenuated without
altering the colour temperature of the lamp.
Release the retaining catch and insert the scrim into the interior
slide; check that it is properly engaged into the 3 channels. Lock
the retaining catch again.
The "half-moon" diffusing scrim may then be oriented in such a
manner as to obtain the desired light effect.
Outrig filter frame.
This filter frame is used especially on the 2 and 5 kW spotlights
in order to increase the service life of the colour filters. Please
consult the fitting instructions supplied with the outrig filter
frame.
Adjustments
Adjustment of the focussing
The focussing is adjusted either by hand or using a pole, by
turning the yellow colour head, which is situated on the side of
the spotlight. Turn the head in a clockwise direction to disperse
the light beam. Turn in an anticlockwise direction to concentrate
the light beam.
Adjustment of the friction of the optical carriage.
The frictional force of the optical carriage on its two translation
shafts may be adjusted in accordance with the wishes of the
operator.
Disconnect the equipment from the mains; open the front door
and place the optical carriage as close as possible to the lens
by means of the focussing head.
The adjusting screw is situated on the left hand side of the
optical carriage. Adjust the frictional force by means of a
screwdriver; when the desired adjustment has been obtained,
retighten the lock-nut.
Azimut (horizontal) positioning.
For the "manual" type of spotlight, the azimuth positioning is
simply carried out manually. For the "pole operated" type of
spotlight, the positioning is carried out by turning the blue colour
head, which is situated on the side of the spotlight. Turn the
head in the desired direction of rotation of the spotlight.
Elevation (vertical) positioning.
For the "manual" type of spotlight, the elevation positioning is
simply carried out by hand, by releasing the clamping lever
situated on the side of the spotlight (see Fig. 1). When the
desired inclination has been obtained, retighten the locking
lever.
For the "pole operated" type of spotlight, the positioning is
carried out by turning the white colour head, which is situated
on the side of the spotlight. Turn the head in a clockwise
direction to incline the spotlight downwards. Turn the white
head in an anticlockwise direction to raise the spotlight again.
Do not exceed the maximum angles of inclination given on the
index plate.
Maintenance
Cleaning and replacing the mirror.
We recommend that the mirror should be cleaned each time
you replace the lamp. Disconnect the spotlight. Allow the
spotlight to cool. Open the front door of the spotlight. Bring the
optical carriage as close as possible to the lens. Carefully
remove the lamp. Clean the mirror using a clean, non-fluffy cloth
impregnated with alcohol.
Cleaning and replacing the lens.
It is essential to clean the lens regulary, in order to maintain the
optimum output from your equipment. Disconnect the spotlight.
Open the front door of the spotlight. Allow the spotlight to cool.
Raise the three tabs for fixing the lens and turn them through
90°. Remove the lens; clean both sides of the lens using a clean,
non-fluffy cloth impregnated with alcohol, replace the lens and
refix it by means of the fixing tabs. Close the front door again.
