1.3 Mounting the Antenna Unit on the Mounting Platform

CAUTION1) Work at high places is dangerous. Always wear a hard hat and safety belt when working on the antenna unit mast.2) Both a service platform and steps to the service platform must be mounted to provide safe access for service personnel. Improperly installed platforms present a hazard to service personnel.

Siting considerations

CAUTIONA magnetic compass will be affected ifplaced too close to the antenna unit.Below are the minimum safe distances for magnetic cpmpassis.

Consider the following points when selectinga mounting location for the antenna unit.

¥ No funnel, mast or derrick should be within the vertical, beam width of the antenna in the bow direction, especially zero degrees –5°, to prevent blind sectors and false echoes on the radar picture. ¥ Fumes from the funnel or other exhaust vent can adversely affect performance and hot gas can distort the radiator. The antenna unit must not be mouonted in a place where the temperture may exceed 70°C.¥ Leave sufficient space around the unit for maintenance ans servicing. See the antenna unit outline drawing for recommended maintenance space.¥ Locate the unit well away from the aerial of a radiotelephone or navigation receiver to prevent interference. Separation of more than two meters is recommended.

1.4 Mounting the Display Unit

The display unit is designed to be mounted on a tabletop or a pedestal (option).

Before mounting the display unit

If Gyro Converter GC-8 (option) is to be used, install and setup the GYRO PROCESSORBoard before mounting the display unit, because of the difficulty involved if done after the unitis mounted, Insstrutions for installtion and setup are in Chapter 4.

Siting considerations

Lpcate the display unit on the bridge in a place where it can be viewed and operated conve-niently. In addition, consider the points noted in the figure which follows.

CAUTIONA magnetic compass will be affected ifplaced too close to the display unit.The minimum compass safe distances for magnetic compasses are

standard compass: 2.7 msteering compass: 1.8 m

Consider the points mentioned belowwhen selecting a mounting location for thedisplay unit.

¥ The orientation of the display unit should be so the operator views the screen while facing the bow. This makes determination of position much easier. ¥ The location should be free of water spray.¥ The daylight bright type radar display sunlight. However, locate the unit out of direct sunlight and away from heat sources because of heat that can build up inside the cabinet.¥ The mounting location should be deter- mined consiering the lengt of the signal cable between the antenna unit and the display unit. (The signal cable comes in lengths of 15, 20 or 30 meters; maximum 100 meters.)¥ Leave sufficient space around the unit for maintenance and servcing. See the display unit ouline drawing forrecommended maintenance space.

2. CONNECTIONS

2.1 Antenna Unit Connections

Two cables run between the display unit and the antenna unit, the signalcable and the antennacable.

When the De-Icer is installed

1) Before beginning any work on the scanner unit, turn off both the DE-ICER switch (S31) onthe sub panel of the display unit and the breaker for the de-icer line at the main switchboardto remove the power (100 VAC, 1ø) to the de-icer. (Turning off the power to the display unithas no effect.)

2) The neck of the scanner unit becomes VERY HOT when the de-icer is working. (The de-icer turns on when ambient temperature is below 0°C.)

2.2 Display Unit Connection

Two cables are terminated at the display unit: the signal cable RW-4839 or RW-6895 and thepower cable. The signal cable, available in lengths of 15m, 20m, or 30m, comes with a connec-tor preattached to it for connection to the display unit.

6) Press the [2] key several times to select OTHER S-BAND.


3.2 Heading Alignment

Antenna unit mounted error (heading reed switch timing error) can be compensated at the dis-play unit.

Figure 3-2 Heading alignment error

Procedure

1) Turn on the power. Press [RADAR MENU] [0] [0] [2] [2] to select HD ALIGN on theINITIAL SETTING 1 menu.

2) Select a target echo (by gyrocompass, for example) at a range between 0.125 and 0.25nm,preferably near the heading mark.

3) Operate the EBL control to bisect the target echo. (The value shown on the display is an-tenna position in relation to ship's bow.)

4) Press [ENTER] to finish.

3.3 Adjusting Sweep Timing

Sweep timing differs with respect to the length of the signal cable between the antenna unit andthe display unit. Adjust sweep timing at installation to prevent the following symptoms:

• The echo of a "straight" target (for example, pier), on the 0.25nm range, will appear on thedisplay as being pulled inward or pushed outward. See Figure 3-3.

• The range of target echoes will also be incorrectly shown.

Procedure

1) Turn on the power. Press [RADAR MENU] [0] [0] [2] [3] to select TIMING ADJ on theINITIAL SETTING 1 menu.

2) Transmit on the 0.25nm range.

3) Adjust radar picture controls to display picture properly.

4) Select a target echo which should be displayed straightly.

5) Adjust the VRM control to straighten the target echo.


3.4 Adjusting Video Signal Level

When the signal cable is very long, the video amplifier input level decreases, shrinking targetechoes. To prevent this, confirm (and adjust if necessary) video amplifier input level.

Procedure

1) Connect an oscilloscope to TP3 on the INT Board (INT-9170).

2) Transmit on the 12nm range. Take trigger at TP10 on the same board.

3) Adjust VR1 on the INT Board so the value of TP3 is 4Vpp. (For secondary display, adjustVR2 for same level.)

3.5 Suppressing Main Bang

If main bang appears at the screen center, suppress it as follows.

Procedure

1) Turn on the power. Transmit on a long range and then wait ten minutes.

2) Adjust [GAIN] control to show a slight amount of noise on the display.

3) Select the 0.25nm range. Adjust the [A/C SEA] control to suppress sea clutter.

4) Open the tuning compartment on the control unit.

5) Set VR901(MBS-L) at two o'clock and then slowly turn VR902 (MBS-T) clockwise tosuppress main bang.

6) If main bang still exists, turn VR901 clockwise slightly, and then slowly turn VR902 clock-wise. Note that excessive main bang erases targets in close range.

3.6 Confirming Tuning

The radar receiver can be tuned both automatically and manually. Confirm that the radar can betuned both automatically and manually.

Procedure

1) Turn on the power. Set the TUNE switch in the top right hand panel to MANU.

2) Transmit on the 48nm range.

3) Adjust sensitivity and picture brilliance. Turn the [A/C SEA] and [A/C RAIN] controlsfully counterclockwise (off).

4) While observing the picture, turn the [TUNE] control in the tuning compartment slowlycounterclockwise (clockwise) more than twice to get best (worst) tuning point.

5) Turn the [TUNE] control slowly clockwise (counterclockwise) to display the longest tun-ing bar.

6) Set the TUNE switch to AUTO and wait about 10 seconds (about four rotations of theantenna).

7) Confirm that the radar found best tuning point. Peak tuning is obtained when about 80% ofthe tuning indicator lights.

3.7 Confirming Magnetron Heater Voltage

Magnetron heater voltage is adjusted at the factory. Confirm that magnetron heater voltage iswithin the prescribed rating as follows:

1) Turn on the radar and select the 0.125 mile range.

2) Press [RADAR MENU] [0] [0] [2] [0] to open the INITIAL SETTING2 menu.

3) Press [5] to select the 5. SCANNER STOPPED field and the TX option.

4) Turn off the antenna switch in the display unit.

5) Connect a multimeter, set to the 10 VDC range, between #12(+) of P801 and the chassis.

6) The multimeter should read 9.2-9.4 V. If not, adjust VR1.

7) “Transmit” on the 48 mile range.

8) The multimeter should read 7.3-8.3V.

9) Press [RADAR MENU] [0] [0] [2] [0] [5] to select the 5. SCANNER STOPPED field andthe ROTATE option.

10) Turn on the ANT MOTOR SW on the scanner unit.
