2.2. Power System Diagram
Power System Diagram
2-4 Figure 2.1 shows the power system diagram of this equipment.
DC power passes through the circuit breaker via the line filter in the power circuit
CBD-1702A, and it is re-input to the power circuit CBD-1702A for generating the supply
voltage to be used inside the equipment. The power circuits are of the high-efficiency
switching type.
This equipment has an overvoltage protection function.
If the input voltage exceeds
about 42 VDC, the power circuit CBD-1702A stops the output of the supply voltage to be
used inside the equipment; if the input voltage exceeds 50 VDC, it turns off the circuit
breaker, thus protecting the equipment from an overvoltage. The protective voltage is set
with the constant in the power circuit CBD-1702A.
The P+12V power supply is active even when the power switch on the operation unit is
turned off. This power supply is used with circuits such as the control circuits in the power
circuits.
When the power switch on the operation unit is turned on, the power supply to be used
inside the equipment is started, and the +5V, +3.3V, +12V, and -12V power supplies are
output for starting the equipment. The +5V and +3.3V power supplies are used mainly
with the ICs of control circuits.
The +12V and -12V power supplies are used mainly with
external interface circuits.
The power output relay for the scanner unit operates in conjunction with the power switch
on the operation unit.
An overcurrent protection function is provided for each power output.
If a load is
short-circuited or exceeds the rating, the protection function works to turn off the output.

Functional System Diagram of NKE-2254 Scanner Unit
2-6 Figure 2.2 shows the functional system diagram of the scanner unit for this equipment.
When the power relay for the scanner unit in the display system is turned on and power is
supplied to the scanner unit, the power circuit starts power supply to each circuit of the
scanner unit. The CPU in the interface circuit is started by starting the power supply, and
preheating of the magnetron is started after initialization. The scanner unit waits for a
communication signal from the display system. A communication link is established when
a communication signal is received, and then the scanner unit is placed under control of the
display system.
While the magnetron is being preheated, the interface circuit sets the operation of each
circuit of the scanner unit according to the initial setting value transmitted by the display
system. After completion of preheating, the scanner unit informs the display system that
the preheating is complete. When the operator performs operation to start transmission, a
transmission start command is sent through the communication line from the display
system, and the scanner unit starts the scanner motor and the transmission.
A transmission timing pulse is generated in the interface circuit and input to the modulator
switching circuit. After high-voltage switching for the modulator, the high-voltage pulse is
further boosted by the pulse transformer and applied to the magnetron for obtaining
pulse-modulated microwave. The radar-signal pulse width and repetition frequency are
specified by a control command from the display system.
The radar signal passes through the duplexer circuit configured with the circulator and
the rotary joint and transmitted into space from the antenna.
A signal reflected from a target is input through the antenna, and then input to the
receiving block by the duplexer function. After the received signal is amplified, it is
converted to IF frequency and log-detected, and turns into a radar video signal. If the
receiving tuning function is in automatic mode, the interface circuit processes the received
signal and automatically controls the tuning voltage to obtain optimum local frequency.
The motor power circuit controlled by the interface circuit is turned on, DC power is
supplied to the motor driver circuit, and the motor starts running. The rotation control
signal output by the interface circuit is supplied to the motor driver circuit after
frequency-voltage conversion in the motor power circuit, by which the motor speed is
controlled. When the safety switch is turned off, power supply to the motor driver is
forcibly turned off, by which the motor is stopped. The radiation bearing of scanner beam
is detected by the encoder.
2-7 The received radar video signal, transmission timing signal, and antenna rotation signal
are sent to the display system. The radar video signal is a non-processed, log-compressed
signal. The antenna rotation signal is an incremental signal, and 2048 rotation pulses and
reference bearing pulses per cycle are used.
When a specified time has passed during the stopping of the communication signal from
the display system, the interface circuit moves into the protection mode, and forcibly stops
the transmission and the scanner unit.

Functional System Diagram of the Display System

Figure 2.3 shows the functional system diagram of the display system for this equipment.
A. Start of the equipment
When the power switch on the operation unit is turned on, the power circuit CBD-1702A
is started, and generated voltages are supplied to the radar processing circuit CDC-1350.
Then, the CPU in each control circuit starts up and performs initialization.
When the power is turned on, the local CPU and the CPU in the AIS processing circuit
CDC-1353, and the CPU in the operation circuit CCK-979 are released from the reset state,
and they initialize the hardware connected to them and wait for a control command from the
main CPU in the radar processing circuit CDC-1350.
When the main CPU is released from the reset state, it initializes the whole system after
the radar plotting/display function. The main CPU sends an initialization command to the
local CPU so as to initialize the radar signal setting, and at the same time it sends a
communication initialization command to the CPU in the operation unit so as to initialize the
operation function.
The main CPU also starts the DSP by writing programs into memory in
the DSP of the ARPA processing circuit, and issues an initialization command to the CPU in
the AIS processing unit so as to initialize the AIS processing circuit.
After that, the main CPU sets the internal condition according to sensor data which is
input through the communication lines of NSK unit, GPS, etc., and it issues an initialization
command to the scanner unit via the communication line so as to initialize the scanner.
System initialization is complete when the scanner has been initialized.
B. Functions of the circuits
The NSK unit NCT-4106A (option) processes gyro signals of synchro or step type,
calculates true bearing values, and periodically transmits true bearing data to the radar
processing circuit through serial communication. As long as gyro signals are supplied,
power is supplied to the NSK unit even when the display system is turned off, and the CPU
is active.
Thus, the NSK unit can continue to calculate true bearing values even when the
display system is turned off.
The CPU in the operation circuit detects the operating conditions of switches and dials on
the operation panel, and transmits the operation data to the main CPU through the
communication line.
2-10 After converting radar signals (radar video signal, transmission timing signal, and
antenna rotation signal which are sent from the scanner) to digital data, the radar signal
processing circuit in the radar processing circuit suppresses unwanted waves, and plots
and displays radar images in accordance with the display screen.
The ARPA processing circuit receives radar signal data for which unwanted waves are
suppressed by the radar processing circuit, and performs target tracking.
The results of
target tracking are sent to the main CPU in the radar processing circuit.
The AIS processing circuit processes AIS communication data which is externally input,
manages the databases of all the received AIS targets, and transmits important target
information to the main CPU.
On the basis of the target information, the main CPU
displays AIS targets and necessary information on the radar display.
The display unit displays the display signals on the LCD panel that are output by the
radar processing circuit.
The brightness of screen display can be adjusted by the
brilliance control on the display unit.
C. Basic radar operation
When preheating of the magnetron in the scanner is finished, the display system enters
the standby state. Pressing TX/STBY on the operation unit places the equipment in the
transmission state.
The main CPU issues a transmission start command to the scanner
unit, and the scanner unit starts transmission and rotation.
Radar signals transmitted by the scanner are input to the radar processing circuit via the
power circuit, unwanted waves are suppressed, and radar images are plotted and
displayed in accordance with the display screen.
The main CPU can process signals in the radar processing circuit or change the screen
display setting according to the operation of switches and dials on the operation unit.
The
results are reflected immediately to the radar image display.

Jumper setting
A jumper post is installed at the location
indicated in the figure at right.
If an external buzzer is connected to the
pin J5-6/7, use the jumper TB1J to
determine whether to open or close the
buzzer contact in accordance with the
status of use under normal conditions.
Normally open contact when the pins 1-2
are jumpered (factory setting)
Normally closed contact when the pins
2-3 are jumpered
CBD-1702A TB1J(1-2) jumpered
If the AIS is connected, connect the jumper TB3J between the pins 2 and 3 (DIRECT).
2-15 To make a connection with the PC plotter and RS232C, connect the jumper TB4J to
RS232C as shown in the picture below.
Connect the jumper TB4J on the RS232C side.

Replacement of Major Units
4.1. Scanner Unit
4.1.1. Precautions for replacing parts in the scanner unit
Follow the precautions below to carry out parts replacement without getting injured.
Confirm that all the radar equipment (if more than one unit is used) is turned off
before you start the parts replacement. For the sake of safety, turn off the main
power circuit breaker.
Wear gloves to protect your hands during parts replacement.
Be very careful not to
drop a tool or part when you work in high places.
Carry out parts replacement while the ship does not roll or pitch much in a bay if
possible.
Be careful that the radiator does not hit anyone during parts replacement.
The
radiator can turn with wind or the like.
4-1 4.1.2. Parts Replacement for the Scanner Unit NKE-2254
[Required tools]
• Tools for removing the cover from the scanner unit
A wrench (width across flats 13 mm for M8 bolts)
• Tools used in each part replacement procedure
[Replacement procedure]
(1)
Before starting the work, turn off the
safety switch at the bottom of the scanner
unit.

To replace the following parts, remove
the cover from the right (starboard) side:
•
Transmitter (magnetron, modulation
circuit, or fan for the modulation circuit)
•
Receiver
•
T/R control circuit
•
Power circuit
•

Loosen the four
hexagon bolts.
4-2 (3) Replace the parts, which need replacement, according to the procedures in the
subsequent sections.
Be careful not to lose screws or brackets removed during replacement.
(4) After the parts replacement, mount the pedestal cover, set the safety switch to ON.
(Be sure to cap the safety switch.)
The packing shall be clean, free from dust and dirt when you mount the cover.
(5) Turn on the radar, and perform necessary operation checks.
4.1.3. Magnetron replacement / NKE-2254
[Required tools]
• A Phillips screwdriver for 4 mm screws
• Tools for removing the scanner unit covers (See Section 4.1.2.)
(1)
Remove the covers from the right (starboard) side (see Section 4.1.2) and loosen
the screws (four M4 screws) to remove the magnetron cover.

length.
Use a shielded secrewdriver because
the contact of the metal tool with
the magnetron causes deterioration
of its performance.
(4)
After having replaced the magnetron, reassemble the unit by following the
disassembly procedure in the reverse order.
Do not forget to tighten the bolts and screws, and do not forget to reconnect the
cables.
Extreme care should be taken to connect the leads (yellow and green) to the
magnetron for prevention of contact with other parts or the casing. Contact
may cause them to discharge.
[Operation check]
After having completed the replacement, follow the steps below to check the operation.
(1)
Turn on the radar and allow sufficient preheating time (20 - 30 minutes in the
STBY mode).
(2)
Start transmission on a short pulse range and change the range to the longer
ranges. Open the service engineer menu and provisionally adjust the tuning.
Whenever operation becomes unstable, immediately return to STBY, wait five to ten
minutes, and then transmit again.
4-4 (3)
After transmitting on a long range for about fifteen minutes, return to the service
engineer menu and adjust the tuning.
Perform the adjustment in the service engineer menu until the tuning display bar
on the display unit reaches the eighth calibration mark.
With the service engineer menu open, also make sure the magnetron current is
shown between the fifth and seventh calibration markings.
4.1.4. Motor replacement / NKE-2254
[Required tools]
• Single-ended wrench (width across flats 17 mm for M8 bolts)
• Tools for removing the scanner unit covers (See Section 4.1.2)

6-32 6.3.2. External Equipment
Connection cannot be established with external equipment for NMEA output.
Description
The following may cause this trouble: connection polarity, baud rate setting, setting for using
external navigator, or output-equipment fan failure.
Location of cause o
Polarity
Procedure
If the connection is correct, the output is LOW at the time of no signal
when viewed with the negative side as reference on the oscilloscope.
Baud rate
Adjust the baud rate to the value defined in the output specifications for
the navigator.
Output-equipment fan
Check that multiple devices are not connected to the same port on the
failure
external equipment.
Signals may not arrive correctly because the
output capacity of the external equipment is exceeded.
Follow the
external equipment specifications.
The true bearing value cannot be displayed correctly.
Description
The setting may not be correct, or the bearing sensor may have a problem.
Location of cause o
Setting
Procedure
The GYRO I/F circuit may not be set correctly.
Check if the setting is suitable for the equipment in use.
GYRO(DATA)
If signal amplification is too low when a step-type gyro is used, an error
Step type
may be posted.
In many cases, the error can occur if the multiple
devices are connected with the same port and the output capacity of the
gyro compass is exceeded.
In only a few cases, electric potential at LOW level of the output signal
increases at that time.
To conform to the input specifications for the
GYRO I/F circuit, voltage at LOW level must be r2.5 V or less.
Voltage
at HIGH level must be r20 V or more.
GYRO(DATA)
If an error occurs intermittently, it may be improved by setting DIP-SW
Synchro type
S4 No. 5 on the GYRO I/F circuit to ON.
However, note that the setting
of S4(5) simply extends time for error determination and does not solve
the essential problem of the gyro.
