About This Manual
Servicepolicy
Intendedaudience
The LDK 20(S) is a sophisticated camera containing
state-of-the-art electronic components which are
designed to provide long-life operation without the
need for maintenance. With this in mind, the service
policy of Thomson Multimedia Broadcast Solutions
endeavourstoensurethathelpwillbequicklyonhand

Structure of this manual
The manual is divided into five sections:
Section 1: Safety Information.
Contains important safety information and should be
read before carrying out any work on the camera.
Section 2: Installation.
Purpose of this manual
Givesinstructionsontheintegrationofthecamerainto

Safety Summary
Cautions and Warnings
This informaton is intended as a guide for trained and
qualified personnel who are aware of the dangers involved
in handling potentially hazardous electrical/electronic
equipment. It is not intended to contain a complete list of
all safety precautions which should be observed by
personnel in using this or other electronic equipment.
When performing service, be sure to read and comply with
the warning and caution notices appearing in the manuals.
Warnings indicate danger that requires correct procedures
orpracticestopreventdeathorinjurytopersonnel.Cautions
indicate procedures or practices that should be followed
topreventdamageordestructiontoequipmentorproperty.
Theinstallation,maintenanceandserviceofthisequipment
involves risks both to personnel and equipment and must
be performed only by qualified personnel exercising due
care.
WARNING
THE CURRENT AND VOLTAGES PRESENT IN THIS
EQUIPMENT ARE DANGEROUS. ALL PERSONNEL
MUST AT ALL TIMES FOLLOW THE SAFETY
REGULATIONS.
Personnel engaged in the installation, operation,
maintenance or servicing of this equipment are urged to
become familiar with First Aid theory and practises.
ALWAYS DISCONNECT POWER BEFORE REMOVING
COVERS OR PANELS.
ALWAYS DISCHARGE HIGH VOLTAGE POINTS
BEFORE SERVICING.
During installation and operation of this equipment, local
building safety and fire protection standards must be
observed.
NEVER MAKE INTERNAL ADJUSTMENTS, PERFORM
MAINTENANCE OR SERVICE WHEN ALONE OR WHEN
FATIGUED.
Before connecting the equipment to the power supply of
the installation, the proper functioning of the protective
earth lead of the installation needs to be verified.
IN CASE OF AN EMERGENCY ENSURE THAT THE
POWER IS DISCONNECTED.
ANY INTERRUPTION OF THE PROTECTION
CONDUCTOR INSIDE OR OUTSIDE THE APPARATUS,
OR DISCONNECTION OF THE PROTECTIVE EARTH
TERMINAL, IS LIKELY TO MAKE THE APPARATUS
DANGEROUS. INTENTIONAL INTERRUPTION IS
PROHIBITED.
Whenever it is likely that safe operation is impaired, the
apparatus must be made inoperative and secured against
any unintended operation. The appropriate servicing
authority must then be informed. For example, safety is
likely to be impaired if the apparatus fails to perform the
intended function or shows visible damage.
FOR SAFETY REASONS THE CPU MUST BE MOUNTED
IN A 19-inch RACK WHICH HAS SAFETY COVERS
ACCORDING TO IEC65.
This product has been designed and tested according to
EN60065.
WHEN TWO CPUs ARE MOUNTED ABOVE EACH
OTHER THE MINIMUM DISTANCE BETWEEN THEM
MUST BE 50MM OR THE RACK MUST BE FORCE-AIR
COOLED.
USE ONLY FUSES OF THE TYPE AND RATING
SPECIFIED.
CAUTION
To prevent risk of overheating, ventilate the product
correctly.
Connect the product only to a power source with the
specified voltage rating.
Only connect a Triax cable from the LDK 6 camera
family to an LDK 6 CPU. Never connect it to any other
base station.
Never connect the Triax cable from a camera to a
CPU of a different family; never connect the LDK
family to the TTV family.
Do not allow system ground currents to exceed 1.5A
in the outer shield of the triax cable or 0.2A in other
cable shields.
It is strickly prohibited to short circuit the inner and
outer shields of a triax cable used to connect a
camera to a base station.

Earthing
The rear of a CPU has two separate screw terminals for
Symbol Colour
Explanation
protective earth

(VE).
Red
High voltage terminal at which a
voltage, with respect to an other
terminal, exists or may be
adjusted to 1000V or more.
VE
Metal
strap
PE
Yellow/Black Live part.
These are normally connected by a metal strap. The
protective earth terminal is internally connected to the
protective earth conductor of the power cable. If required,
the central earth connection wire of the studio can be
connected to terminal PE.
Yellow/Black This marking indicates that the
operator must refer to an
explanation in the Instruction
Manual, or that a specific
component must be replaced by
the component specified in the
documentation for safety
reasons.
In normal circumstances the connection between the
protective earth and the video earth should not be broken.
The metal strap may be removed only if the studio (or OB
van) is equipped with separate protective and video earth
systems. Under these circumstances the video earth
terminal must be connected to the central functional earth
potential (video earth) of the studio. This earth potential
should have functional protective and noiseless earth
(FPE) qualities as stated in the VDE regulation 0800/part2.
A low impedance interconnection of both earth conductors
must be provided at the central studio earthing point.
White/Black
Protective earth (ground)
terminal.
Cathode ray tubes
Components marked
on the circuit diagram are critical
for safety and include those specified to comply with X-ray
emission standards for units using cathode ray tubes and
those specified for compliance with various regulations
regarding spurious radiation emission.
WARNING
THE UNIT MUST ALWAYS BE CONNECTED TO
PROTECTIVE EARTH.
When servicing units that use cathode ray tubes (CRTs),
the cathode ray tubes themselves, the high voltage circuits
and related circuits are specifically chosen so that they
complywithrecognizedcodespertainingtoX-rayemission.
Mains Lead Wiring for UK Users
The wires in the mains lead are coloured in accordance
with the following code:
Consequently, when servicing, replace the cathode ray
tubes and other parts with specified parts only. Do not
attempt to modify these circuits as any unauthorized
modification can increase the high voltage value and
cause X-ray emission from the cathode ray tube.

if you wish to change to a different type of lens or the
lens is not supplied with your camera, back focus,
white shading and auto iris adjustment procedures
may have to be performed.
Internalsignals
Set jumper X3 to position BC to get the nominal
sawtooth. This is used for checking amplitudes.
Set jumper X3 to position AB to get a small sawtooth
(approximately 25% nom.). This small sawtooth is
used for checking painting or colour temperature
ranges.

• Back Focus Adjustment
To inject an external test signal first set jumper X3 to
position CD (test input). Connect the external test
signal to connector X4-1/2. The nominal value of this
signal is 700 mV without sync.
To adjust the back focus of the lens refer to the
