General Description of the Miniature Unit KSA 5
A. Why miniature unit?
The anti-collision unit KSA-5 is 'a miniature unit. However, with respect to
image resolution and range it corresponds approximately to the ordinary types.
The device is miniaturized by the following measures:
1. Limited to only one visual indicator,
_
2. Gyrocompass terminal abolished, thus eliminating north-7
? .
stabilized image.
3. Manual Nerificitien of klystron tuning with omission of tuning amplifier.
4. Partial use of subminiature tubes.
I
5., Use of a statically focused picture tube.
6. Inclusion of a 10 ... 12 kw magnetron.
7. Low power consumption, less than 350 w on the secondary side of the trans- ?
former as a result of points 'l ... 6.
8., Practical compact structural form.
Theunitconsistsessentiallioftwoipprooin,of which one con?
tains the transmitter with the appropriate modulation and the major portion
of the receiver, while the other contains the picture tube with the appro-.
priate beam deflection, the remainder of the receiver, and the target-
measuring instruments. Since the individual devices contain within them-
! r? r
selves their appropriate power supplies, PLuM:7herl,housings are superfluous.
A pivot antenna and a miniature set of transformers are the only re-
maining parts of the unit. 1
The following structural advantages also result from these measurbs,:.
The transmitting and receiving device can, since it contains no control knobs, be
mounted on any free _space and must merely be accessible for repairs. Its location
should, as much as possible, be in a free space beneath the antenna, in order to avoid

The visual indicator, located opportunely on the bridge, can be mounted direc ly
against the front window wall. On the sides too no free space is required, since all
the control elements are located on the front plate and in case of repairs the entire
insert must be removed from its sheet-metal housing 17 the observer.
The transformer can be located anypiace on board; the antenna is outside the
premises in the open.

C. Mechanical Structure of the Unit and Its Breakdown
a) The antenna
The antenna is a normal parabolic reflector with a 220 v direct-current
motor and a 400 cps torque indicator It contains the usual tubular conductors or
cm elements, such as a swivel joint, a horn emitter, and a parabolic reflector, and
also contains the drive transmission .the one synchronizing contact, the prelim-
inary contact, the torque-indicator sensor, a cable terminal board, and two cable-
insertion glands. When assembled on board it is fed by only one cable (NKK,
stationary) from the device through one of the two glands. The wires are screWed
onto the terminal board. A diagram of the cable connections is to be found in the
cover of the junction box. The wires continuing on to the motor emerge again
awl
through the second gland, whereA are
connected to the motor terminal board. They
are already cabled at the factory.
b) The junction boxes
The two housings for the transmitting-receiving device and the visual
indicator are secured by means of vibration dampers to the given mounting angle
or mounting plate. We thus obtainAactlaccidumecumm an elastic suspension, so that
the 1101=210E11?11 rigid NICK ship's cabiing cannot be connected directly to the hous-
ings. To each of these two devices there thus belongs a small junction box,
which is rigidlyLbolted into the ship's wall and into which the rigid cables are

introduced. Their cable wires terminate in both boxes on ship clamps, thus
ensuring convenient assembly aboard ship. A cabIc?connection diagram is-i-eeer? \
,zte&on the cover of each junction box. Short flexible wires belonging to the ;
boxes, wires which sometimes carry on their tips a multiple plug socket, then
connect them with their instruments.
? The junction box of the transmitting?receiving device is merely a through?
switching or junction terminal box and contains no electrical structural ele?
ments. It is traversed by all the conductor wires, which are fed into the
device and arrive in the box as a single MKK cable, reaching two concentric
60J1 cables, which are screwed by means of sockets directly onto the housing
of the transmitting?receiving device. The multiple plug socket-alee:wW14- at the
end of the flexible junction?box cabling can be separated from the device by
means of a handle by releasing a fast?locking mechanism, so that after addit?
ional unscrewing of both concentric cables and separation of the tubular?con?
ductor train leading upwards the entire device is free, can be screwed off the
0
wall, and replaced, if necessary.
The junction box for the visual indicator, in contrast to the junction box
for the transmitting?receiving device, is not only a through?switching and
junction terminal box, but is also the central branching point of all the MKK
ship's cable belonging to the device. There are no other connections between
the individual devices other than through this box (see complete wiring diagram),
A cable coming from the transformer terminates in it, as well as a cable coming
directly. from the power supply (removed before the transformer). Another one goes
through the transmitting?receiving device junction box to the transmitting?re?
ceiving device, while still another goes to the antenna. The cable to the visual
indicator itself is flexible, is an integral part of the box, and is not -assembled,'
on board, as are the other cables mentioned above. It carries on its tip, just as
in the case of the other junction box, multiple plug sockets in an elbow casting
the plugs of which are located on the visual indicator itself. The elbow casting

of the multiple plug sockets is, to be sure, bolted to the rear wall of the
visual indicator from the inside. The counter?plugs sit securely on the Visual
indicator insert. If this insert is removed from its sheet?metal housing, the
multiple plugs can be used as an adapter connection, after disconnecting the
elbow casting and thus the flexible cable from the sheet?metal housing, and the
insert can consequently be put into operation outside the housing, The two con?
centric 60xicables coming directly from the sockets on the housing of the trans?
mitting?receiving device do not terminate directly on the housing of the visual
indicator, but in sockets on the junction box. From here on they are led to?
gether with the flexible cable through the multiple plug sockets to the housing
? of the visual indicator. Thus upon removal of the visual?indicator insert all
the lines are automatically disconnected. Moreover, the inclusion of the con?
centric cables in the flexible cable produces better conditions for the case
where the visual indicator is mounted on a swivel bracket.
? The visual?indicator junction box contains, in addition to the ship clamps
for the cab es and a ground terminal, a relay, an auxiliary antenna switch, and
5 safety
. The relay switches off the antenna motor on both lines
(+ and ?) and the t.Irque?indicator voltage on the phase V, both for the torque? ;
indicator sensor in the antenna and the torque?indicator receiver in the visual _
indicator. By means of the auxiliary antenna switch the antenna can be put into
its rotational motion without turning on the rest of the apparatus. Three safety
-s lie at any given time in the phase V from 115 v/400 cps., and, to be slime
in the line continuing on to the transmitting?receiving device,.in the one lead?
ing.to the. visual indicator, and in the one feeding the two above?mentioned torque
indicators. The other two protect the antenna motor in the plus and minus line
from 220 v onwards. The purpose and size of all the safety likritsmS" is engraved
in the insulating cover plate.

front cover is opened, the .receiver, together with its power supply, is visile
on the mid-section of the device. There is nothing on the cover apart from the
air-exhaust aperture of the ventilator. If the mid-section is pushed even fur- .
ther open, the transmitter mounted on the back of the rear wall becomes visible.'
While all the voltage-carrying parts (maximum voltage + 300 v) are covered to ?
protect them from contact, and the device continues to operate when the front
cover is opened, a safety contact interrupts the feed voltage for the entire
unit, when the mid-section is opened forwards, and short-circuits the high-
voltage present in the transmitter. The safety evices, which are located on
the underside of fthe mid-section, belong both to the transmitter as well as to
the receiver. receiver. Their rgiacesc and size can be read off a plate adjacent to the.
devices.
The majority of the linesleading from the rear portion, secured to the
wall, to the central, flappable portion go through spring contact and terminal
strips mounted on the central portion. Only the concentric I-F cable goes ,
directly from the 1.4.0 amplifier output to the socket on the outside wall of the
device. Thus it is possible, after removing the hinges, to separate the spring
contact strips from the terminal strips (in which case the spring contact trip
te,
remains hanging on the stationary rear portion on the flexible cable tre.e3, to
disconnect the I-F cable on the amplifier and to unscrew an external light
shutter on the duct leading the I-F cable through the casting of the mid-section;
it is also possible to quickly separate from each other the cover, the mid-
section, and the back of the rear wall.
The individual partial chassis, r=uch as the I-F amplifier located on the
right side of the mid-section, the amplifier power supply located on the left,
the high-voltage power supply located in the upper right part of the stationary
rear portion, and the pulse generator located below, can be conveniently removed
_
by their handles, after unscrewing the screws designated in red on the chassis.

a
To be sure, both concentric cables mut be disconnected from the I?F amplifier;
this can be done easily by means of the accompanying special keys; the high?
voltage conducting line must be soldered tightly onto the high?voltage power
supply.
On the middle of the receiver side the klystron is mounted, together with
certain accompanying structural elements, such as those belongi!ethe mixing
center, directly on the latter or on the casting chassis. Its flappin?
sulating.cover plate contains an insulating punch key for mechanical tuning of
the klystron. On the rear portion of the transmitter side the testing circuit
was mounted, together with its large structural elements, such as the testing
tube with its heating transformer, the magnetron with its heating transformer,
high?voltage. coupling capacitors and feedback resistance, in part directly on
the casting chassis or on small stationary brackets located in the housing.
Also located on the bracketfor the testing tube is a socket for connecting
an oscillograph measuring cable for the possible measurement of the magnetron?
'voltage pulse. The testing circuit touches the chassis in only one place with
its ground band, and to be sure also touches the magnetron itself. The short?
term currents of approximately 5 amp flowing in this line could otherwise., as
chassis currents, give rise to disturbances.

_1n addition, everything possible was done to separate power supply of
Fi3ST CF
receiver and transmitter (different cables and emission).- The receiver space
? is "hermetically" sealed. Only two 115 V power cables (supply for reflector voltage
' and anode voltage of the seaway interference eliminator coming from the viewer
and a crystal current measuring cable) enter and leave the receiver space. The
cables leave and enter the space through condenser leads.
The cast plate of the center piece contains two large openings for
structural elements which do not belong on its front side electrically, i, et,
in the receiver space. Therefore the openings are shielded on the front side
with a socket and a cap. The pipe carries the ventilating motor with propeller
'and a relay group with a rectifier set is located behind the cap. Relays avoid
instantaneous full-operation of the cold unit, permit it after approximately 3
minutes and turn-on series resistance into the primary lines of high-voltage anode
'transformers and magnetron filament transformers when changes in impulse width
'occur. The adjustable series resistance for high-voltage is located under the
cap. Rectifiers deliver 24 volt DC voltage as circuit voltage for all 24 v
relays. (This includes allrelays except for the one located in the high-voltage
circuit of the viewer). The ventilating motor, on the other hand, is fed by
another-24 v DC rectifier. It is located on the receiver circuit chassis. Its
voltage, produced by the receiver circuit, is the only one not utilized in the .
receiver space and transferred out of it. These transfers therefore are made by
condenser leads. Resistors which are located on the line to the motor and serve
for voltage reduction, have been distributed to both lines (elimination of radio
interferences in motor).
-------5 All lines entering or leaving the transceiver, i.e. all lines which after
passing the junction box run together in a KKK-ship cable to the viewer junction
ox, run through a box marked with cable entry, which in turn is mounted on the
?-large housing as a small box. The interior of the box is divided into single

"E'Ir
pulses picked-up by internal lines, thus preventing them from entering the circuit
as interference voltages. Counterparts for multiple connector sockets of the
, flexible junction box cable are located on its bottom side.
d) The Viewer
The viewer can be easily removed from its sheet metal housing by handles
mounted on the front plate after releasing the quick-opening lock on the side.
It consists of a chassis in front of which the supporter for the front plate is
mounted. The front plate is mounted on the supporter. The electronic tube section
is left of the insert and the low-voltage circuit right. The high-voltage circuit
.for the picture tube is located on the top. A transparent insulant cap protects
it against dust. The picture tube socket with the mechanical deflection unit is
located in the middle. Operational devices are accessible on the front plate.
Both circuits may be easily removed after unscrewing the 4 screws marked
in red. Both chassis are electrically connected via spring and terminal strips.
f The high-voltage clip on the picture tube must be stripped when removing the
high-voltage circuit section. The electronic tube section can be opened to the
: side after unocrewing two screws. Cable connections to the mounting chassis
remain undisturbed because additional parts such as push-button switch, control
potentiometer, deflection coil, etc. are organically part of the tube section.
The picture tube socket is connected via an enclosed adapter,. This set-up
guarantees continuing operation of the tube section even when taken out (indivi-
dual parts are accessible when trouble shooting). Proper utilization of space is
provided.
In big repairs the tube section can be removed easily by unscrewing the
4
hinges, detaching the coaxial IF cable (the last IF amplifying section is mounted
Hon-the tube section as an encased little box) and removing the anode cap of the
7iid-ilieep tube. Furthermore, all other cables run through two spring and terminal

FiRsT ItO OF TEA:
The front plate can be separated from the rest of the insert-1ov,
after removing the red marked screws. Wires running to bearing disks - illumi-
nation lamp and control panel - lighting switch are interrupted at a spring-terminal
strip. The engraved bearing disc is stored in rolls on its back side. One of them
is shaped as a friction wheel and connected over a gear drive with the drive knob
marked "azimuth". The little illumination lamps are well Shielded so that no inter-
. el 047-Nti"-SS
ference is. created ilk the disc on the screen. ai instimieffect may be regulated.
The range indicator drive knob marked 'distance" is connected via an intermediate
clutch and a slipAW clutch with the range indicator aggregate on the basic chassis.
In addition there is a semipermeable mirror located in the image field opening
which is connected with thefillotter addition.
The plotting device may be mounted on the front plate panel with the aid
of a clasp hook and a claw lock. The glass surface which serves for writing,
can be illuminated. Little bulbs which are inserted in a circular cast fastening
ring can be turned an by means of a switch incorporated in the lower edge of the
device. Current is supplied by two contacts which upon mounting automatically
restore connection with the rest of the installation and which are located left
and right in the upper section.
In similar manner, an observation tube can be mounted on the front plate
instead of the plotting device. The observation tube is kept in place on the top
by a quick-opening lock and displays aj5t,hb,!rAece at the end which conforms to
the face and eliminates 3hA-shots: -111;;TU3;e- is shaped in such manner that in ,

The tube can be pulled out after loosening the front sipport strip (upper screw with
right and left thread). The cast mounting of the picture tube becomes visible.
The mounting has 4 coils just before the tube neck constriction. They serve for
center. correction. Farther to the rear, on the east, are mounted the turn
indicator and a change gear which% transmits the turns to the internally visible
deflection coil. Its collecting rings and brushes are visible from the outside.
:The second and the adjustable synchronization contact With its can is also located
there. The deflection coil can be turned against the turn indicator with a snail-
shaped socket-head mom cap screw which is located at the rear :theft in a
metal block. The entire gear part can be pivoted somewhat for adjustment purposes
; against he chassis after unscrewing a clamping screw. The turn indicator itself
; has sHmULetal shielding and a flywheel disc on its axis which is supposed to prevent
; any gear-chatter marks on the screen. The line ends of the turn indicator are
connected on a terminal board on the lower side of the chassis. In addition, there
are some high-load resistors there some of which belong organically to the tube
' *lotion, also the synchronizing relay, some control potentiometers, push-button
switch and on an insulating ledge frame condensers and resistors which belong
to a. sweep range in pairs.

A synchronization process between antenna and deflection coil can set in
during the first antenna rotation which can last for one antenna rotation only.
A transformer ratio of 1 : 18 is incorporated between antenna main axis receiv-
ing selsyn/and deflection c oil transmitting selsyn. Consequently, the trans-
mitting selsyn makes 18 rotations during an antenna rotation and runs through
an equal amount of identical angular positions,. The receiving selsyn goes through
the same angular positions as the receiving selsyn. Thus, antenna and deflection
coil rotate with the same angular speed and remain in a stationary angular re- .
lationship to each other. In a turned-off position, however, the antenna can
shift by multiples of a selsyn. When the installation is turned on, the selsyns
among themselves assume the identical angular position and continue to run with
the same angular speed. However, there is'a different angular relation now
between the antenna and the deflection coil. In order to avoid this, a cam has
been incorpor,ted on the main antenna axis and on the cogwheel of the deflection
444.-zrz--,,,. ?
coil. EachAoam actuates one contact per rotation. If these contacts are not
actuated simultaneously, the cvnchronizing relay arrests the receiving selsyn
during the moment when the viewer's cam runs up. Only after the antenna cam
also reaches its contact, it will be released again. Both have to reach their
contacts simultaneously after one revolution and then can keep on running. The
antenna is mounted on board of ship in such manner that its synchronizing con-
tact is opened when the emission is measured as being between 90? and 108?
against the ship forward direction. The contact in the viewer is shut-down when
the scanning beam sweeps between 91? and 107? measured against the upper position.
This results in a forward oriented picture i.e. all targets located ahead of the
ship appear on the screen above the center point, those located on the starboard
side to the right, those boated on the portside to the left and those astern below

! the identical can. (the beginning of the actuation applies) if the antenna
FIRS-Ts L:'/E Cis TEC
emits forward. This contact shorts on each revolution a line with respect to
ground; this line is terminated at the other end on a RC cambination. This
combination forms electrically the forward mark guiding voltage which is added
to the picture as a. bright line. In a correctly functioning synchronization .
this mark has to be written from the center point up. If the synchronization
does not materialize then the picture and the forward mark can rotate on the
screen. In spite of this, targets which coincide with the forward mark, mean
obstacles located, inthe path of the ship, eventhough the forward mark may be
. trace* somewhere on the side.
d) Pulse Functions of Transmitter and Pulse Width Switching.
.1:257-(-Frt-
The impulse generator in the transmitter generates with its
generator four trigger impulses per circuit period from the 400 cps voltage by
means of quadruple switching even if the circuit frequency may change
same. Positive trigger impulses are transmitted via a cathode stage into a con-
centric 60 o?hhi cable which at its end in the viewer is sealed with 6o.0 On the same
chassis, this impulse travels through a continuously-adjustable transit time
'circuit to the exciter part. Here, the worn-out impulse is. again rejuvenated
in a blocking oscillator stage and then guides via a separator stage the excite-
blocking oscillator. The length of the 0.5/us- Lapulse is determined here with the
aid .of a. transit time circuit. In a 0.1p-impulse, the guidance is performed with
a video relay from the viewer, the transit time circuit is turned off and
replaced by &amen condenser. Switching is coupled with the range switch (from
'3. an-0.5 ys).. When switching the impulse width from 0.5 to 0.1 is, the second
-relayaocated below the shielding cap of the transceiver center section. is .
- activated and turns on a resistor in the primary lint to the high voltage trans-

former. Small impulse width means smaller resistance in the line, thus the heat-
ing voltage increases secondary in time because smaller Impulse width means less
, additional heating. The modulation stage is a circuit of the "hard tube pulsar"-
. negative
type. The modulation stage 'passes A impulses to the magnetron cathode of 5.5 kv
and makes it oscillate during the duration of the applied impulse voltage.
0 The Composite Section
Because the same antenna is used i;tor sending and receiving, an electro-
yf-
nic switching is provided in the tubular-eonduc-tor.,(cailled Idnposite section).
It consists of two outer steam tubes one of which is located in a tie line towards
Ur magnetron. The second tube, preionized by DC voltage, is located in the tUbular
?conductor lanot&on which leeds from the main line to the receiver. If the travs-
miter is emiting, the two tubes spark and Ass cause a short in their t4SSImp

ord that it appears that through line transformation they smoothly
_
pass the main line tram the sender to the antenna. The receiver is blocked
off and the high transmitting voltage can not damage the sensitive mixed crystal
'nibs mixer head. Roth tubes darkeu if the transmitter ceases to supply energy.
The passage to the receiver is free. Instead of the electronic short circuit of
the blocking tube, the real short circuit of the metal end plate appears. It
effects a short circuit in the main line by its position and lip transformation.
Thus the magnetron is separated fram the antennm part of the ttbUINFW-MaCtor and
the line from the receiver to the antenna appears as &smooth continuous part.
f) Receiver Characteristics
5 Receiving signals which reach the end of the tubular conductor (called
mixer head) leading to the receiver wind up on the mixed crystal. The auxilliary
oscillations .of the klystron are fed to the mixer head with the aid of a directional
-coupler. Their frequency must be either 35 megahertz above or under the frequency

Its main section is located in the transceiver, the rest in the viewer. Both
sections are connected with each other by a concentric 60 ohn cable. It is termi-
nated on its viewer end in the IF -unplifier chassis with 60 ohm. After rectification,

The sweep in the viewer is activated by the trigger Impulse traveling

in a mall bifilar to an impulse transformer wound on a coil form and artifically
-delayed in a rectifier -condenser-tesistance combination. Thus it is fed to the
sweep multisvibrator. The sweep multi-.vibrator generates, if not influenced, after
every trigger impulse an impulse which is samewhat longer as needed for the longest
sweep range. During normal operation, however, its back flank is decided before-
hand by a reverse control circuit. The reverse control circuit is activated at the
moment when a determined current flows through the deflection coil. Thi current

In order to put the installation into operation,. the push button marked
"stand?by" is pressed. This sets the transformer into operation and all tubes
are being heated. A large portion of the. required DC voltage is being blocked
for approx. 3 minutes by a thermal time relay. Subsequently to this, the in?
stallation is ready for operation. Upon pressing the band button, the direct?
ional antenna begins to rotate and the set is operational.
Tuning the Screen Picture
Basic brightness(0)is tuned until a scanning line barely appears on the
picture screen around the center point. By c-ollt-ealliilg the contraAt (in

)
may be moved for approximately ? 10 mm.
If a subsequent adjustment of the tuning becomes necessary, it may be performed
by pressing the button "fine tuning". The instrument should under normal cir?
cumstances indicate maximum deflection of approximately 491A. Pressing the
button "modulation current" transforms the instrument and it should indicate
approx. 38,,.481A modulation current.
Mark Brightness
The button "mark brightness" controls the brightness of the forward mark
I'cs
and the variable range circle. Both marks are turned?off on left leflaeti-on.
Range Indicator
The variable measurement circle can be focused on the desired target by
operating the "range" button. The distance can then be read on the meter.
Every distance range can be continuously expanded to the double distance
by meant of the "beam" button. Thus the possibility of adjustment to a de?
? sired map scale exists.'

In case the azimuth of an object should be measured it is necessary to
turn-up the dial illumination knob ()
a until the grade scale located on the
edge of the bearing disc becomes clearly visible. Then the picture center point
is brought under the center point marked on the bearing disc with the aid of the
double knobs (?-)$) 4, This position must be checked before every measurement*
. because the earth's magnetic field can cause a picture displacement. The
bearing line on the bearing disc is now focused on the target to be measured by
means of the 'azimuth' knob. The value is indicated on the scale dial above the
zero Mark. The mark is mounted horizontally above the picture center point on
the edge of the picture frame. The measured angle is in reference to the forward
direction of the ship.

* The voltage fails when the door contact is interrupted in opening the
rear section of the instrumrnt. (See 115 V, 400 cps -1 Loops).
Stablized in Phase V with the Si 2 in junction box H 5 and in Phase U
with the Si 6 in the S.E. (Transceiver).
Phase V circuit II branches off from Phase V in the transceiver and con?
nected directly through in stand?by.
A small resistor is located in the 0.75
and 1.5 meters per second range and in the other ranges larger series resistors
are in the line. (Switched over with relay Rs 4 and Rs 5; see 115 V, 400 cps ?
Loops).

1) Power-Supply Voltage 7-V is available from the mains operated power supply
when the converter is in operation, i.e., when the stand-by key is pressed and
in operation .
Comes out of junction box H 5 over junction box G5 and cable inlet.
Made safe in Phase V with the Si 2 in junction. box H 5 and in Phase 11
the Si 3 is used in the transmitting instrument.
Voltage drops when the door contact is broken by opening the door on
the back of the instrument section ( see 115 V. 400 cps - loops).
2) lie'klystron also gives off cm-energy in the "readiness" position, because in
this position reflector voltage from the visual apparatus is present. (See reflec-
tor voltage loop).
Ttneable in the visual aTTaratus (coarse with screwdriver - fine with
knob - press knob in!)
When cm-energy is given off then there is a deflection on the instrument
in H 5 (see Point 3).
3) Crystal current indication on the instrument in H 5 when the klystron operates
(see Point 2).
4) Bias voltage for the R8 262 and R8 203 tubes is adjustable on the W 230, "IF:.
amplificatiOnflon the IF-amplifier.
_5) Anode voltage for swell suppressor. The voltage is present only
_
in connec-
tion with a printed (or pressing) range key, and when "Sea" 1" or "Sea" 2" is
is operated.

Comes from H 5 (See Swell?suppressor Anode voltage loop).
Made safe togethel' with H 5 (see Si 1 in junction box g 5).
Voltage is taken from 150 V.
6) When first turning the instrument on with a range key, wait about 3 'minutes
for the thermorelay to heat.
6) Control impulse for swell suppressor ? circuit.
Comes from the impulse generator.
Available when the stand?by key is pressed and in operation..
The impulse generator is protected by Si 5 in 0 5.
