Prices are valid in US and Canada only. Home Products FAR The magnetron in the transceiver module will demagnetize if it contacts ferrous material. When dismounting the transceiver module, lay it on its side or on top of non-ferrous material as shown below. Open the rear cover of the antenna unit. Disconnect plugs P, P, P and P If the PM is installed, also disconnect plug P Unfasten two bolts and remove the transceiver module.

Unfasten the four fixing bolts from the cable gland at the base of the antenna unit. Remove clamping ring, rubber gasket and washers. Pass the signal cable through the cable entry hole in the antenna unit mounting platform.

Trim the cable so about 80 cm of it protrudes past the cable gland. Fabricate the signal cable RW as shown below. Slide a washer, and fold back armor. Slide a washer, rubber gasket, washer, and clamping ring in order.

Cut the armor around the washer so it is level with the washer. Nip the armor between two washers, and trim the excess armor from around washers. And then pass the shield between the clamping ring and the washer as shown below. Fasten the clamping ring with the screws. Insert the cores except coaxial wire to the connector with the opener. Set the transceiver module to the antenna unit, push it in until it stops, and then tighten fixing bolts 4 pcs.

Fasten the shield wire to the wing nut on the transceiver module. Confirm that all screws are tightened and all wiring is properly made. Confirm that waterproofing gasket, bolts and tapping holes of antenna unit are coated with silicone grease. Close the antenna unit cover torque: 2.

The signal cable comes with a connector preattached to it for connection to the monitor unit. Fabricate the power cable as below. Use DPYC Cut armor of the cable by 40 mm. Remove insulation of wires by about 10 mm. Fix crimp-on lugs to the cores. Peel paint of the armor by 40 mm. Cover the end of armor with vinyl tape. Four cables are terminated at the processor unit: the antenna unit cable, display unit cable, control unit cable and the power cable.

Cables other than the power cable come with a connector preattached to them for connection to the processor unit. For the power cable, use DPYC The power cable is connected to the terminal board on the rear panel and the signal cable from the monitor unit is connected to the DVI-D connector. Other cables are connected to the printed circuit board 03P Note that the cable fabrication for each end is. Cable fabrication for each end is the same.

Terminal opener. Press the terminal opener downward. Insert the wire to hole. Remove the terminal opener. Pull the wire to confirm that it is ecure. Refer to the table to connect sub-displays. The figures below and on the next page show the location of the fuse and the jumper connector on the PWR board. Also, adjustment of the overvoltage detection circuit is required. Add or remove the jumper connector P and change the fuse. Rotate R21 fully clockwise on the PWR board. Connect a variable transformer between ship's mains and the input power terminal board TB-1 of the processor unit.

Adjust the variable transformer output i. Turn on the radar and rotate the R21 counterclockwise gradually until the overvoltage detection circuit functions i. Lower the output voltage of the variable transformer and confirm that the radar automatically turn on with a voltage lower than VAC or VAC.

Gradually increase the output voltage of the variable transformer and confirm that the overvoltage detection circuit functions at V or VAC of the variable transformer output. Assemble and connect the processor unit. Remove the top cover of the processor unit. Open the SPU assembly block. Transmit the radar on 48 nm range and rotate the GAIN knob to show of the gain bar.

Roll the trackball to choose the MENU box at the right side of the screen and then push the left button. Roll the wheel to choose 1 ECHO and then push the wheel. Push the wheel to initialize automatic tuning. After a while, echoes appear on the screen. When this message disappears, the tuning is completed.

If necessary adjust the GAIN to show echoes clearly. Push the right button twice to close the menu. You have mounted the antenna unit facing straight ahead in the direction of the bow. Therefore, a small but conspicuous target dead ahead visually should appear on the heading line zero degrees. In practice, you will probably observe some small bearing error on the display because of the difficulty in achieving accurate initial positioning of the antenna unit. The following adjustment will compensate for this error.

Select a stationary target echo at a range between 0. Operate the EBL control to bisect the target echo. Welcome to ManualMachine. We have sent a verification link to to complete your registration.

Construct a suitable service platform from which to install the antenna unit. Serious injury or death can result if someone falls from the radar antenna mast.

Turn off the power at the mains switchboard before beginning the installation. Connection of an incorrect power supply can cause fire or damage the equipment. Use only the specified power cable. Fire or damage to the equipment can result if a different cable is used.

Do not install the monitor unit, processor unit or control unit where they may get wet from rain or water splash. Attach securely protective earth to the ship's body. Page 9: Mounting 1. Those items contain organic solvents that can damage coating and plastic parts, especially plastic connectors. Page 10 1. Page 11 Assembling the antenna unit The antenna unit consists of the antenna radiator and the antenna unit chassis, and they are packed separately.

Fasten the antenna radiator to the antenna unit chassis as follows: 1. Page 12 1. However, do not lift the antenna unit by the radiator. Always hold the unit by its housing. When using a crane or hoist, lift the unit by the hoist rings which should be fastened to the bolt fixing covers of the antenna housing. Page 13 4. Bow mark 5. Fasten the antenna unit to the mounting platform with M12x60 hex bolts, nuts, flat washers and seal washers.

Page Monitor Unit The monitor unit can be flush mounted in a console panel, or mounted on a desktop using the optional accessories. Prepare a suitable monitor locally. Recommended monitor: SXGA x , aspect ratio Page 15 1. Page 16 1. Page 17 The hand grip is optionally available for the desktop mounting monitor unit. Hood option When it is too bright in the daytime, use the optional hood to shade the screen.

Page Control Unit 1. Desktop mounting: Fasten the fixing plates to the fixing holes with the hex head bolts supplied. Flush mounting: Fasten the display unit to the mounting location, and then attach the fixing plates with four self-tapping screws. Attach the hood to the display unit the hood is outside of the fixing plates.

Page 19 Fixing with KB fixing plate 1. Fix the KB fixing plate to the bottom of the control unit. Fix it to a desired location with self-tapping screws local supply. Fixing without KB fixing metal 1. Page 20 1. Page 21 1. Pass the cable derived from RCU Connect the connector of the cable to J Clamp the copper part of the cable with the cable clamp. Inside of RCU Page 22 1. Screw M3x8 3. Pass the cable from this hole.

In here, clamp the copper part of the cable with the cable clamp removed at step1. Page 24 1. Page Wiring 2. Also avoid running the cable in parallel with power cables. Page Antenna Unit 2. When dismounting the transceiver module, lay it on its side or on top of non-ferrous material as shown below. Open the rear cover of the antenna unit 2. Page 27 Antenna unit, front view, cover removed 6. Fabricate the signal cable RW as shown below. Page 28 2. Nip the armor between two washers, and trim the excess armor from around washers.

And then pass the shield between the clamping ring and the washer as shown below. Fasten the clamping ring with the screws. Clamping ring Rubber gasket 25B 9. Page 29 Set the transceiver module to the antenna unit, push it in until it stops, and then tighten fixing bolts 4 pcs.

Fasten the shield wire to the wing nut on the transceiver module. Push in transceiver unit until it stops. Page 30 2. The signal cable comes with a connector preattached to it for connection to the monitor unit. Fabricate the power cable as below.
