Identification and Status
To indicate the status of a drawing, a box with the
numbers 0 to 9 is shown in the bottom-right of the
drawing. The number that is crossed-out is the status
number of the drawing. For example, in the illustration
below, the status is 1.
A sticker is used on the units themselves to identify
them and to indicate their status. For example, in the
illustration below, the top line is the 12-digit number
that identifies the unit type.
The first four digits of the number on the second line
represent a date code (year, week); the next four digits
represent the serial number for that week.
The number in the grey area indicates the status of the
unit. The last two digits represent the number that will
be given to the next status. However, if these two
digits are contained in a box, then this is the current
status. For example, in the illustration above, the
current status of the unit is 01.
Line 1 3922 407 00000
Line 2 123456AA0101
Line 3 VR/0123456789
Line 1
This is the code number of the printed circuit board
assy. (PCB)
Line 2
This is the serial number of the PCB. The first 6 digits
and the 2 letters are for internal use. The last four digits
reperesent the date of the manufacturing: wwyy.
Example:
123456AA1402 means the PCB is manufactured in
week 14 of the year 2002.
Line 3
This is the status of the PCB.
The digit after the first slash is the status. If there is no
number before the slash, it means that the status is
less than 10, a 1 before the slash means the status
is between 10 and 19, a 2 before the slash means
between 20 and 29 etc.
Example:
- VR4567891012 means status 4
- VR3/78901234 means status 37.

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.
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
comply with recognized codes pertaining to X-ray emission.
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.
Handle the cathode ray tube only when wearing shatterproof
goggles and after discharging the high voltage completely.
Earthing
The rear of a CPU has two separate screw terminals for
protective earth (PE) and video earth (VE).
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.
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.
WARNING
THE UNIT MUST ALWAYS BE CONNECTED TO
PROTECTIVE EARTH.

4-2 Technical Manual LDK 100 - Camera Head Adjustments
Introduction
This camera is factory tested and adjusted for operational
use. Under normal circumstances, the internal automatic
calibration procedures do not need to be started and the
internal potentiometers do not need to be adjusted.
There are two situations that might require some
realignment of the camera:
a. When a lens is fitted.
b. When a printed circuit board has been replaced.
When a lens is fitted the following alignment procedures
should be carried out in the order given:
1. Run the internal 3200K calibration procedure.
2. Adjust the white shading via the menu system.
3. Adjust the flare.
4. Adjust the back focus (see lens manual for this
adjustment).
If a printed circuit board is replaced, refer to table 3-1 to
see which adjustments must be carried out to realign
the camera. For a particular board, carry out the
procedures in the order given.
If it is discovered that the camera is misaligned, the
following procedures are given as a guide for competent
service personnel, who have a thorough knowledge of
the camera and have the use of calibrated equipment,
to realign the camera.
If no improvement can be achieved or an adjustment is
out of range, please contact your local supplier or the
nearest Thomson Multimedia Broadcast Solutions
Service Centre.
The camera head adjustment procedures are designed
as separate units. Within a numbered procedure do not
change the position of switches or jumpers unless
instructed to do so in the procedure.
These adjustment procedures are for the Camera
Head. However, for practical purposes the Triax Adapter
is used together with the camera head to facilitate some
measurements. Other adapters can be used for these
measurements.
