Fig.1-1 Simplified Block Diagram The trigger pulse is generated on DU board in the display unit and sent to the modulator on MD board in the scanner unit. The modulated signal triggers the magnetron and high frequency pulses are transmitted from the radiator. The target echo received by the radiator is frequency-converted by the MIC. 60 MHz IF signal is amplified in the scanner unit and then sent to the display unit. DU board in the display unit processes video signal to show target echoes on the LCD display. Bearing pulse (BP) and heading signal (HD) are also delivered to the display unit from the scanner unit.

1.2 Display unit

1.2 Display unit TX trigger pulse is generated by gate array, U79 and sent to the scanner unit. The video signal from the scanner unit is A/D converted and sampled by gate array, U78. Echoes in each sweep are stored on the V-RAM via gate array, U79. Upon receiving the heading pulse, the stored data are output to the LCD in four gradations, according to echo strength.

1.2 Display unit

The display unit consists of PNL board (03P9330), DU board (03P9320) and LCD unit (03S9461). Each board functions as below. PNL Board (03P9330) This board functions as a man-machine interface, equipped with keys, LEDs for panel-illumination, and a buzzer. DU Board (03P9320) According to the range setting, gate array U79 generates TX trigger pulses in specified pulse repetition rate. Reference oscillator output is divided by the data from the CPU to decide the PRR. The pulse repetition rates differs slightly from set to set to prevent the radar interference. The video signal from the scanner unit inputs to the video circuit on the DU board. The video circuit includes FTC circuit that rejects the reflecting signals from the rain and snow. CPU switches on or off the FTC according to control panel setting. The video signal is converted by the A/D converter into seven-level digital signal, and input to the radar signal processing circuit in the gate array U78. The digital video signal is sampled in U78 with the sampling clock corresponding to the range setting. Further, when the interference rejecter is turned on, each video signal is correlated with the corresponding transmission to eliminate or reduce the radar interference signals. The processed video signal by U78 is written into VRAMs via U79 for indication. The bearing signal and heading signal are input to serial-to-parallel converter and then applied to G/A U79 individually. Heading error obtained at heading alignment in installation menu is stored in EEPROM U28, and used by CPU to calculate the correct antenna direction. TX time delay data is also stored in EEPROM U28. Unlike R/θ coordinate sweep, LCD display employs X-Y coordinate method similar to so called TV- sweep method. U79 converts the R/θ video signal to X-Y coordinates using formulas, RSIN θ and RCOS θ. The coordinate-converted video signal is written and maintained onto VRAM for trail indication. The data writing/reading onto/from the VRAM is carried out by U79 in time sharing. U79 retrieves data from VRAM to display it on the LCD display. Scanner unit control data is converted to serial data by RS-422 interface, U27 and sent to the scanner unit through a balanced RS-422 line. The control data includes transmission on/off, TX pulsewidth selection, Gain and STC signals. The data from the navigational aid is received through photo-couplers U10 and U11.

1.2 Display unit

The unit operates on universal voltage ranging from 10.8 V to 31.2 V DC. This range covers the voltage requirement for 12 V/24 V ship’s mains 10 % lower and 30 % higher. The ship’s mains is supplied through a noise filter to the pulsewidth-controlled DC-DC converter which generates the stable voltages; +5 V, +12 V, +8 V and –24 V. The ship’s mains is also supplied to the scanner unit, bypassing the power supply circuit in the display unit. +5 V is mainly used for the digital circuits, +12 V for the video circuits, +8 V for the backlight, and –24 V for the LCD display. The DC-AC inverter consisting of Q33, Q34 and T1 generates 210 V AC for the backlighting of the LCD display. If the power supply is connected to the radar in reverse polarity, the reverse-polarity protector activates so that the fuse is blown off to prevent the damage to the unit. The power supply circuit contains low- and high-input voltage protector.

1.3 Scanner unit

1.3 Scanner unit In the scanner unit, the TX trigger from the display unit is modulated to use it for triggering the magnetron. The received echo is fed to the MIC and down-converted to 60 MHz IF signal. Auto-gain and auto-STC circuits are not in the scanner unit, but in the display unit.

1.3 Scanner unit

INT board (03P9322) INT board mainly consists of CPU U4 that includes the RAM, ROM and analog ports, RS-422 interface U5, a motor drive circuit and a gain control signal generator. CPU U4 receives control panel settings on the display unit through the RS422 interface U5. The D/A converter U2 converts Gain, A/C RAIN, and tuning control signals from digital to analog. A/C SEA and A/C RAIN circuit consisting of Q1, Q2 and Q3 outputs GAIN CONT signal to IF board. The CPU U4 controls the stepping motor drive circuit, Q4 to Q7 to keep the antenna rotation speed constant. The heading signal (HD) from the lead switch is mixed with the bearing pulse (BP) by Q9 to Q11 and sent to the display unit. The ship’s main is supplied to the power supply circuit on the MD board via INT board. MD board generates +5 V, +12 V and -6 V for the use on INT board. Lead Switch

IF Amplifier board (03P9321) The 60 MHz IF amplifier consists of Q1, Q2, U1 and U2, and provides the bandwidth of 7 MHz. The tuning level detector, U3 to U8, detects the main bangs to indicate the tuning level.

Fig.1-6 Block Diagram of IF AMP Board (03P9321) MIC (RU-9458) The circulator in the module switches between the transmitting and receiving microwave circuits so that the transmitting radio energy is efficiently transmitted to the antenna without leaking to the receiver side and the receiving radar signal from the antenna is sent with efficiency to the receiver without leaking to the transmitter side. The receiver circuit consists of diode limiter, balanced mixer and FET oscillator. The diode limiter protects the balanced mixer from the excessive input power. The mixer converts the input microwave signal to the 60 MHz IF signal. The oscillator is voltage-controlled and outputs the signal to the mixer. MD board (03P9270) The MD board consists of a power supply circuit and a modulator. There are two DC-DC converters in the power supply circuit: one generates –6 V, +5 V, and +12 V and the other magnetron heater voltage and TX HV. In the DC-DC converter, drivers Q803 and Q832 are driven by PWM controllers, U801 and U805 respectively. The magnetron current, –6 V, +5 V, +12 V, +8 V (magnetron heater voltage), and TXHV can be measured at the test point TP804. The modulator in TX circuit receives the transmitting pulsewidth selection signals, PL-A and PL-B, from INT board, and the trigger signal from the display unit. One-shot multivibrator U851 generates the transmitting trigger pulse of which the pulsewidth depends on range setting. VR851 and VR852 adjust the output power of the magnetron. The pulse is boosted up by T851 and applied to the magnetron.

Chapter 5 Troubleshooting 5.1 Error Messages The following messages appear to call the operator’s attention to missing heading or bearing pulses. Check the antenna cable for damage or discontinuity when these messages appear. Table 5-1 Error Messages Message NO HEADING PULSE NO BEARING PULSE

Meaning Heading pulse is not applied to the CPU on the DU board. The heading mark disappears. Bearing pulse is not applied to the CPU on the DU board. Radar automatically changes from TX to ST-BY mode.

5.2 Troubleshooting Matrix table The troubleshooting matrix table on the next page helps the service technician to quickly identify defective pcb or block. To use the table, locate the symptom in one of the three columns of the table. Possibly defective circuits and their likelihood of defectiveness, identified by a circle, star or triangle, corresponding to 70 to 80 %, approximately 20 % and a few percent respectively, are listed in each column. Numeral inside circle shows degree of possibility; the smaller the number, the higher the possibility.

Note: Before consulting the table, check the ship’s mains (input voltage at J1351#1(+) and #2(-) of the display unit: 10.8 to 31.2 VDC) and the power fuse.
