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.

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.

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.

2.5. DIP-SW/Jumper Setting 2.5.1. Power Circuit CBD-1702A 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).

Even when the display system is turned off, the JMA-5200mk2

operates receiving power from the display system side. Thus, the switching of TB105 setting is not necessary. (This switching does not cause any problem.) The JMA-5200MK2 needs the switching of TB105 setting.)

Chapter 4 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.

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) [Replacement procedure] (1)

Procedure

TT brilliance

Check that TT brilliance is not set to 0.

ARPA/ATA circuit

Replace the ARPA/ATA circuit.

A Keyboard(DATA) error message is displayed. Description Operation can be performed, but a Keyboard(DATA) error message is displayed.

Location of cause o Connection

Procedure The operation unit may be connected to the AUX connector instead of J4.

Check the connection of the operation unit.

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.
