FE-700 system configuration

PRINCIPLE OF OPERATION

The FE-700 uses ultrasonic pulses to detect the seabed and other underwater objects. The display unit contains all basic electric circuits and logic processor. Electrical pulses are converted into acoustical energy in the transducer fitted on the ship’s hull. The processor measures the time of pulses travelling between the seabed and transducer and displays the water depths in the graphical form or other forms.

The transducers have a specific beam width with respect to their working frequency, 50 kHz or 200 kHz. The high frequency has a narrow beamwidth and is immune to aeration when the ship is going astern or in rough weather. The low frequency has a wide beamwidth and more powerful sounding capability.

1.3 Turning On/Off

1.4 Tone and Brilliance

1.Turning on: Press the POWER Switch. Self-test starts, showing the condition of the logic circuits. The program number is displayed.

ROM: OK

DRAM: OK

SRAM: OK

BATTERY: OK

PROGRAM NO. 0252297002

2.Select a mode with the MODE Selector. The NAV position of the selector is recommended for general use. Display color is amber by default but may be customized. The unit of measurement is meters. You can freely select another mode at any time.

3.Turning off: Press the POWER Switch again.

Wait at least 5 s before reapplying the power.

Note: When two transducers are installed, make sure which transducer is used.

Note: When lat/long data input error occurs, “EPFS” ERROR appears on the screen. (EPFS: Electronic Position-Fixing System such as GPS receiver)

1.	Press the BRILL key. The tone and brilliance
	setting window appears.
			LOW ▼	▲ HIGH
		BRILL:	8
			LOW -	+ HIGH
		TONE:	3
2.
	Press the [+] or [-] key for desired tone (in
	reality, Contrast).
3.	Press the [▲] or [▼] key for desired
	brilliance. Pressing the BRILL key also
	changes the brilliance from minimum to
	maximum and vice-versa.

Note: Tone or brilliance must be adjusted within 10 seconds after pressing the BRILL key. Otherwise the tone and brilliance window will be erased.

1.5 Panel Dimmer

1.Press the DIM key. The panel dimmer setting window appears.

LOW - + HIGH

DIMMER: 5

2.Press the [+] or [-] key for desired illumination of the control panel. Pressing DIM key also changes the illumination level.

1.6 Display Mode

The Mode Selector choose the display mode among NAV, DBS (depth below surface), HISTORY, LOGBOOK, OS DATA, HELP, and MENU.

CAUTION

DBS is not a water clearance below keel.

Do not use this mode in shallow waters to avoid grounding.

1.6.1NAV mode

The depth from the transducer to the seabed (bottom clearance) is shown on the screen. Note “BELOW TRANSDUCER” appears at the bottom of the screen in this mode.

Default is,
Color:	Amber
Range:	Automatic range switching
Window:	15 minutes

Shallow depth alarm: 20 m

NOTE: These parameters can be customized to your preference and the last setting is used at a next switch-on. This is true on all other modes.

1.6.2DBS mode

The Depth Below Surface mode provides a draft-adjusted depth reading and will be useful in referencing to the nautical chart. The draft should be adjusted by the DRAFT key according to the actual draft value. If you find any difficulty to check for the draft value, use the NAV mode.

When the DBS mode is selected, the message “Confirm and set ship’s draft to use DBS mode” appears. Confirm ship's draft and set it by referring to section 1.12.

BELOW KEEL (when the draft setting is –10.0 to –0.1) or BELOW SURFACE (when the draft setting is 0 to 30.0) appears at the bottom of the display and the draft value appears at the upper right-hand corner in the DBS mode.

1.6.3HISTORY mode

This mode provides a mix of Contour and Strata displays. The Contour display can be scrolled over the past 24 h while the right side Strata display (layers of different colors according to reverberation strengths) shows the latest sounding for 5 minutes.

Pressing the [+] or [-] key moves the Contour display forwards or backwards, respectively.

If the range scale for both the Contour and Strata display must be the same. If they are not, the message “OUT OF RANGE” appears.

The update of the contour data may take max. one minute. Wait for one minute to display accurate contour if you change the range scale.
