Chapter 1. GENERAL 1.1 Outline The antenna unit uses a Log IF amplifier. The scanner unit is the same as that of FR-2115 (12KW) and FR-2125 (25kW). The difference between 6 kW and 12 kW sets is the use of different type of the magnetron, and different setting of magnetron current. The features are;
6 pulselengths enabling echo size on the screen to be similar in all ranges. Flash ROM enabling program update to use a PC. Non-interlace, high-resolution display (1024q768 dots). Improved short-range performance using shorter pulselength and higher repetition rate than before.

TX The trigger pulse from the SPU (Processor) Board is delivered to the MODULATOR Board which outputs the signal to oscillate the magnetron, and then radar wave is emitted from the radiator. RX The 9.4 GHz echo signal received by the antenna is converted to 60 MHz signal by the MIC, amplified by IF Amplifier, and fed to the SPU (Processor) Board as a video signal. It is digitally processed and then displayed on the CRT. The SPU Board contains a video amplifier. Auto Plotter (optional) The following signals are applied from the SPU board to the ARP-10/17 Board: Heading, Bearing pulse, Video, Trigger, Bearing in AD format, and Ship’s speed (contact closure or NMEA 0183). Target acquision and tracking are performed on the ARP Board. Target data, target position, CPA, TCPA, Speed, and Course, are displayed on the screen. Plotter (optional) Data such as latitude and longitude in NMEA format is delivered from the SPU Board to the RP Board. Plotter data generated on the RP Board is output to the SPU Board and processed to display them on the screen. The plotter menu is generated on the SPU Board.

Start-up Sequence Radar start-up sequence
Process 1. The soft start circuit activates to protect the power ON/OFF relay contacts. 2. The input voltage monitor checks for abnormal voltage. When ship’s mains is abnormal the ON/OFF relay trips off. 3. The inverter comes on and output all line voltages. The LED comes on and the inverter goes off when overcurrent is detected. 4. ROM, RAM, I/O port, custom IC, AGDC and VRAM are initialized. 5. The system is initialized using EEPROM and DIP switch data. 6. The timer starts counting down from 3 minutes (time remaining for warm-up of magnetron). 7. Checks for the absence/presence of a gyro signal. 8. Checks for the absence/presence of the ARP and RP Boards. 9. The SPU Board starts operating. Note) When H-sync signal is not applied to the CRT unit, no HV is generated, resulting in nothing on the screen. 10. The bearing scale, countdown indication, etc. appear. 11. EEPOT memorizes the preset value. 12. The screen is degaussed automatically. 3-minute warm-up can be skipped by pressing [ENTER] several times while pressing and holding down [HL OFF]. (Do not release this information to user.) 13. Three-minute warm-up ends. 14. The radar goes into stand-by. 15. Checks for presence of BP (Bearing Pulse) signal. 16. The tuning circuit goes into “short search mode.” 17. When the range is changed, the tuning circuit goes into “short search mode.” 18. Panel settings are written onto the EPROM. 19. Time data are written onto the EPROM.

The video signal from the RF Unit is applied to J2 of the SPU Board. The video level is adjusted through the menu so that the main bang level is about 2.2Vpp at the output of EEPOT, U92, #5. The video signal from an external rader can be connected to J458. The video level adjustment for the external rader must also be made through the menu. The ARP video which inputs to the ARP Board is GAIN-, STC-, and A/C SEA adjusted.

Auto Tuning Function The system provides auto tuning mode which eliminates the adjustment of the receiver for maximum echoes. The “Tune Initialization” is required after not only the installation but also the replacement of RF unit, magnetron, MIC, and SPU board, so that the tune control voltages for each pulse are memorized onto the EEPROM. The figure below illustrates how the tune initialization takes place. First, full search is performed using a long pulse to find the tuning point (a). Next, short search is performed using all pulses to find tuning points (b). After the initialization, the pulselength used before the tune initialization is selected. Full search: Varying tune control voltage (TUNE CONT) from about 5 V to 32 V, the maximum tune indicator voltage is found and that tune control voltage (a) is memorized. Short search: The tune control voltage changes between the tune voltage (a) plus and minus 2.5 V for fine tuning. When the radar is set from ST-BY to TX, short search is made twice. When pulselength is changed, short search is made once.

Tuning Indication The tuning indicator extends more than 80% of its full length on all ranges at best tuning. The self-test result display reads the tune indicator voltage.
Manual Tuning When tuning mode is changed from auto to manual mode, the tuning control voltage (a) found in full search is selected. In manual tuning mode, the graphical tuning control voltage indicator appears on the screen. The minimum scale is 4.9 V and the maximum scale is 32 V.
Tuning Circuit Figure below shows the tuning circuit. Tune control voltage is output from DJ1, #7 on the SPU board.

Main Bang suppression Level (MBS L) is set to 0.
2)
EEPOT, U14 is set to minimum. (EEPOT initialization with “L” level of U14 #7)
3)
EEPOT gets into step-up mode (U14 #2 is H.) to measure output video level at each step.
4) 5) 6) 7)
The step is changed by pulses applied to U14 #1. The step where the output level is 2.2 V is memorized. EEPOT gets into step-down mode (U14 #2 is L) to find and stores the step number where the output level is 2.2 V. Averaging the step numbers found in steps 3 and 4 above, and saving onto eepot. The stored value is not erased when power is turned off. MBS L is reset to the value previously used. The value obtained in step 5 is stored onto the EEPROM. Thus, the EEPOT can be set for both video signals from the scanner unit and the external radar.

Echo averaging (EAV 1/2/3) 1)
Remarks on the echo-averaging feature Echo averaging is a useful feature when used properly. If used improperly, however, the result could be disastrous.
2)
Objective and principle of echo averaging The main objective of echo averaging is to discriminate targets (flocks of birds, other ships, fishing floats, etc.) hidden in sea clutter, and stably display long range targets (ship, buoy, island, etc.) which alternately appear and disappear on the screen. Normally, unstable echoes such as those from sea clutter and noise appear at random positions with every rotation of the antenna. To distinguish real target echoes from clutter, the picture is stored and averaged over successive picture frames. If an echo is solid and stable it is shown in its actual intensity. Unstable echoes are reduced in intensity. The following illustrates how echo averaging EAV 1/2/3 work.

Echo Stretch 1/2 and Enhanced video 1. Echo stretch 1:
Enlarges the echo in bearing direction. The same echo appears on the next sweep.
2. Echo stretch 2:
Enlarges the echo in range direction. The signal is integrated in the video amplifier.
3. Enhanced video: The echo is enlarged to increase the number of memories to be filled with the data. D 0LQLPXP HFKR VL]H RQH GRW E 6LJQDO OHYHO RU PRUH F (FKRHV ZLWKLQ GRWV IURP VFUHHQ FHQWHU FDQQRW EH HQKDQFHG G 7KH PD[LPXP RI WDUJHWV FORVH WR WKH FHQWHU FDQ EH HQKDQFHG

Trail Copy Trails can be continued even when the range is changed to a next larger or smaller range scale. Note, however, that when the range is changed, no trail generated for targets outside of the previous range. Example 1) Range scale changed from 3 nm to 6 nm The trail starts for targets more than 3 nm.
Example 2) Range scale changed from 6 nm to 3 nm The pixels used for echo trailing are enlarged, so the displayed trail looses fineness slightly.
Thin Trail Thin trail is generated for the echo level of 8 or more, and the echo size of 8 or more (bearing direction) x 3 or more (range direction). The width of echo trail may become bigger depending on the size and shape of the target.

Check of ARP and RP board Connection The system checks the connection of the ARP and RP board every power on. If the CPU on the SPU board fails to communicate with the ARPA or RP board, the related display does not appear on the screen, but also the ARP and/or RP line is not displayed on the self-test result display.
ARP-15 vs. ARP-17 The hardware of ARP-15 and ARP-17 is the same, but the ARP-17 has an additional EEPROM. The software is different between ARP-15 and ARP-17. Major feature of ARP-17 is; 1)
Automatic tracking
2)
More target to be tracked. (increared to 20 targets from 10 targets)
3)
Guard ring (guard ring targets of 11)
4)
Scenario test
5)
Reference target speed
ARP-10 The ARP-10 is also used for Model 1832 series and FR-7062 series radors.

ARP-10 Block Diagram
1)
ARP-10 dose not require QV echo adjustment at installation, unlike other existing ARPs. No check point for QV echo is provided. The ARP display can be turned on/off thru the ARP menu. The ARP data appears even when ship’s speed and gyro data are not supplied.
2)
The ARP board is checked whether it is installed or not at every power-on, using the communication line between SPU and ARP boards. When the ARP display is on thru the menu and the ARP board is not fitted, the message “ARP is not connected” appears.
3)
When the target is not acquired, carry out the self test at TX condition. TRIGGER/VIDEO/BP/HD must be OK, and FE-DATA 1/DATA 2must vary depending on the gain setting. The lower the gain setting, the smaller the FE DATA value. The FE DATA must not exceed 1000 with the maximum gain setting.
4)
The program is stored on the flash ROM, not PROM, so a program writter MT-08 or PC is required for updating the program.

Target acquisition by Auto plotter (ARP-10) 1. Conditions for manual acquisition
Within 9 scans, the target must be detected near the cursor position. Target echo must be smaller than land echo (800 m or less in the radial or circumference direction) at the front-end processor. ¡ Target must be within acquisition area: 0.1 to 16 nm. ¢ The number of acquired targets in not as many as 10, including the target automatically acquired. £ No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected.
2. Conditions for automatical acquisition
The target must be detected for five consecutive scans within the automatic acquisition area. Target echo must be smaller than land echo (800 m or less in the radial or circumference direction) at the front end processor. ¡ Target must be within acquisition area: 2.0 to 2.5 nm and 45oeach side of heading line. ¢ The number of acquired targets in not as many as 10, including the target manually acquired. £ No signal error (TRIG, HD, BP, VIDEO, GYRO) shall be detected.
3. Automatic tracking
A tracking target is judged as a lost target when no return is received for nine consecutive sweeps. When the system detects a loss of a tracking target, the target symbol becomes a flashing diamond. A lost target will be reacquired and tracked when acquisition condition again becomes satisfactory. ¡ Automatic tracking is discontinued when the target moves out of the acquisition range (less than 0.1 nm or greater than 16 nm).
Target discrimination A target measuring about 800 m or more in the radial or circumferential direction is regarded as a landmass and not acquired or tracked. Echoes smaller than about 800 m are regarded as true target.

ARPA target acquisition and Tracking (ARP-17) 1. Conditions for manual acquisition
An echo from target must be received for three consecutive sweeps and scans within the acquisition area. The target echo must be smaller than the and echo data (at the front end processor). ¡ A target must be within the acquisition area : 0.2 to 32 nm. ¢ The ARPA can acquire 20 targets. £ No signal error (TRIG, HD, BP, VIDEO, gyro) shall be detected.
2. Conditions for automatic acquisition
An echo from target must be received for three consecutive sweeps, and seven consecutive scans within the acquisition area. The target echo must be smaller than land echo data (at the front-end processor). ¡ The target must be within acquisition area: 0.1 to 32 nm (or 24 nm) depending on initial setting. Target echoes behind a land echo within the acquisition area cannot be acquired automatically. ¢ 20 targets can be automatically acquired. £ No signal error (TRIG, HD, BP, VIDEO, gyro) shall be detected.
3. Automatic tracking
A tracked target is judged as a lost target when no return is received for nine consecutive scans. ¡ ¢
When the system detects a lost target, “LOST TARGET” appears on the display and the ARPA symbol blinks. A lost target will be reacquired and tracked when acquisition condition again becomes satisfactory. Automatic tracking is discontinued when the target moves out of the acquisition range (less than 0.1 nm or greater than 32 nm). An acquired and tracked target, which moves behind a land echo, will be declared as a lost target.

Block Diagram Power DC Power Supply Circuit (03P9223) The power supply circuit consists of a main-inverter, a sub-inverter, and a protectors. A P.F (Power Failure) signal of “Low or 0V” is generated when the main-inverter cannot work normally. This signal is sent to the RP-17 and all data is stored before shutdown.
Main-inverter When the power switch is pressed, +12V regulator Q5 starts operating, and power is applied to the input voltage detector and switching regulator control circuit. The switching regulator is turned on with the input voltage of 21.6 V or more, and turned off when the input voltage is 19 V or less. The main-inverter derives +/-12 V from the input voltage.
Sub-inverter The sub-inverter derives +115 V for the CRT circuit from +/-12 V, output of main-inverter. +5 V and +32 V for tuning control is generated by a regulator from +12 V.
Protector The protector activates when the input voltage is lower than 19 V or higher than 43 V. The protector in the power supply line for antenna motor trips when the current is 8 A or more for more than 2.5 seconds. The TX-HV protector circuit is turned on when 8 A flows on the +12 V line. The short circuit protector for +115 V is provided in the sub-inverter.

A P.F (Power Failure) signal of “Low or 0V” is generated when the main-inverter cannot work normally. This signal is sent to the RP-17 and all data is stored before shutdown.
Main-inverter When the power switch is pressed, +12V regulator, Q5 starts operating, and power is applied to the input voltage detector and switching regulator control circuit. The switching regulator is turned on with the input voltage of 85 V or more. The main-inverter derives +/-12 V. The switching frequency is adjusted by VR1 to 22.5 kHz.
Sub-inverter The sub-inverter derives +115 V for the CRT circuit from +/-12 V, output of main-inverter. +5 V and +32 V for tuning control is generated by a regulator from +12 V.
Protector The protector activates when the input voltage is higher than 135 to 150 V (for 110 V sets), turning off relay K2. The rush current protector, Q11 controls the current which flows into smoothing capacitors. The Q11 is bypassed when the transformer T1 outputs the voltage designed. The protector in the power supply line for antenna motor trips when the current is 8 A or more for more than 2.5 seconds. The TX-HV protector circuit is turned on when 8 A flows on the +12 V line. The short circuit protector for +115 V is provided in the sub-inverter.

2.3 Scanner Unit General New cast aluminum scanner gearbox and new series of streamlined antenna are employed on the FR-2115 and FR-2125 radars. These are not compatible with the traditional Furuno scanner gearbox and radiator used for a long period. The mounting dimensions are remained unchanged. Radiator A feeder waveguide is built-in the radiator XN-12 AF, XN-20 AF and XN-24 AF for easeinstallation. The XN-20 AF and XN-24 AF are the same electrical characteristic with XN-3 A and XN-4 A respectively. Gear Box The mounting dimensions, the size of the gear box, and cabling layout have not been changed from the traditional Furuno radars. Changed is the radiator mounting bracket for a new radiator. The gear box can be equipped with a motor of either 24 rpm or 42 rpm type. RF Unit The 10 kW and 25 kW RF units are the same in size. The magnetron of 25 kW is a new type, smaller in size. The RF modulator generates short pulse 1 (S1) which has pulselength of 0.07 us and pulse repetition rate of 3000 Hz. Traditionally, the S1 is 0.08 us and 2200 Hz. The magnetron current monitor circuit ensures a defective magnetron being found easily. When the magnetron is short- or open-circuited, the magnetron current detector reads 1 to 1.5 V.

Chapter 3. ADJUSTMENT
Hazardous Voltage This equipment uses high voltage electricity which can SHOCK, BURN or cause DEATH. Always make sure the electrical power is turned off before attempting to change a component or inspecting the inside of the equipment. A residual charge may exist in capacitors, even with the equipment turned off. Always short all supply lines to the chassis with an insulated screwdriver or a similar tool before touching the circuit. Working on the Scanner Unit Mast Work on the scanner unit mast is dangerous, and doubly so if the proper precautions are not taken. 1. Post an appropriate warning sign near the display unit to indicate that work on the scanner unit is being performed, to prevent accidental application of the power to the scanner unit. 2. Wear a safety helmet and always be aware of where the scanner radiator is.

Chapter 4. MAINTENACE
Hazardous Voltage This equipment uses high voltage electricity which can SHOCK, BURN or cause DEATH. Always make sure the electrical power is turned off before attempting to change a component or inspecting the inside of the equipment. A residual charge may exist in capacitors, even with the equipment turned off. Always short all supply lines to the chassis with an insulated screwdriver or a similar tool before touching the circuit.
Working on the Scanner Unit Mast Work on the scanner unit mast is dangerous, and doubly so if the proper precautions are not taken. 1. Post an appropriate warning sign near the display unit to indicate that work on the scanner unit is being performed, to prevent accidental application of the power to the scanner unit. 2. Wear a safety helmet and always be aware of where the scanner radiator is.

4.8 Notice on Replacing Major Parts MAGNETRON NOTE) The magnetron emits a strong magnetic field. For this season, remove a wrist watch before performing the replacement and use a non-magnetic screwdriver to dismount the magnetron. The estimated life of the magnetron is 2000 hours, (including time in stand-by), however actual life depends on usage. 1. Turn off the power. 2. Dismount the transceiver module. 3. Dismount and replace the magnetron. 4. When a new magnetron is fitted, turn on the power and measure magnetron current. See Chapter 3 for heater voltage rating, and potentiometer to be adjusted. 5. Allow at least 30 minutes under ST-BY for pre-heating. 6. Transmit on a long range and measure magnetron current. Readjust magnetron current if necessary. 7. Allow at least 30 minutes under TX for frequency stabilization. 8. Carry out “tune initialization.” 9. Reset “TX Hours”and “On Hours” on the INSTALLATION SETUP menu.
MIC The MIC can be replaced individually. However, the replacement should be made inside the room where no radar signal is received. The Tune Initialization must be made after the replacement.
SPU Board Settings of the MAIN and INSTALLATION menus are stored onto EEPROM U100 on the SPU Board. Before replacing the SPU board, write down all menu settings and installation settings. After the replacement of the SPU board, menu setting and installation setting must be carried out referring to the record.
