6 FOREWORD Thanks you for purchasing the ONWA KEC-30 Electronic Fluxgate Compass. Your equipment is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless properly installed and maintained. Please carefully read and follow the operation, installation and maintenance procedures set forth in this manual. We would appreciate feedback from you. Thank you for considering and purchasing ONWA. 1

7 FEATURES The KEC-30 is a Electronic Fluxgate Compass designed with ONWA`s advanced LCD high definition display technology. This compass provides a wide range of applications for any type of ships at sea and vehicles on land. The main features are Perfect for use as heading sensor for Radar/ARPA, AIS, ECDIS, scanning sonar There are no mechanical parts such as gimbals or rotating motor, thus the compass is free from routine maintenance It uses a fluxgate magnetic sensor in conjunction with a microprocessor to display accurate heading. Chinese and English menu display The KEC-30 can correct magnetic deviation manually or automatically. 2

The following window appears: MENU HEADING DISPLAY MAGNETIC AUTO HEADING ADJUST TRUE MANUAL HEADING ADJUST HEADING ALIGNMENT SETTING LANGUAGE SETTING TIME SETTING OUTPUT SETTING FACTORY DEFAULT SETTING Choose when TURE, If external input NMEA data contain Lon/Lat information KEC30 would use it to calculate "Magnetic Variation" to show HDT direction otherwise show HDG direction. Choose when MAGNETIC orientation. whether Input any voyage data, Are show HDG 9

15 1.5.2 Auto Heading Adjust The compass has been calibrated during manufacture. This calibration will be satisfactory for almost all installations. If you have a steel vessel, or some other factor which causes the compass to perform poorly, the calibration procedure will adjust compass characteristics to compensate. The calibration should only be done if the compass is known to be inaccurate. If the KEC-30 display as constant offset (e.g. the compass reads 3 degrees high on all bearings), simply rotate the Fluxgate Sensor case to align bearings with the ships compass. It is not necessary to re-calibrate the compass as described below. If the KEC-30 has inconsistent variation on different headings, the following calibration procedure can be carried out. This procedure should only be done in calm waters with adequate sea room. In the menu select "AUTO HEADING ADJUST" and press [ENT] key. The following window appears: AUTO HEADING ADJUST Auto heading adjusting! Please keep constant speed less than 2 minutes for each turn Cancel [ESC] OK [ENT] 10

16 Press [ENT] to confirm make corrections, return to the main screen message will appear to make corrections, while the main screen of data per second update S E W N HDG: 224 SOG: 0 4 kt COG: 211 Auto heading adjusting... Steer the vessel in clockwise direction with constant speed less than 2 minutes per each circle until the following correction success message appear. If correction success the following message appear: S E W N HDG: 224 SOG: 0 4 kt COG: 211 Auto heading adjustment success! If correction fails the following message appear: S E W N HDG: 224 SOG: 0 4 kt COG: 211 Auto heading adjustment failed! The message goes away after 6 seconds. In case of correction fails repeat the above steps until the correction is successful. 11

17 1.5.3 Manual Heading Adjust Manual Compensation is a supplement to the type of single orientation parabola to adjacent 10 degrees. But this method could only be done by qualified personnel. 1.

Use up, down key to select the direction angle need to be modified, then use left, right key to increase or decrease the number of angle in Degree. The highest may adjust Press [ENT] key to save. Note: Anyway ship's magnetic compass and electronic fluxgate compass shows each azimuth are unlikely to maintain consistent Heading Alignment Setting Adjustment of heading might be needed during the installation. Usually a fixed error in all direction would exist. It is due to the mechanical error when fixing the fluxgate sensor KFG-25. The function "Degree Amend" is used to correct this error. 1. In the menu select "HEADING ALIGNMENT SETTING" and press [ENT] key. The following window appears: Heading alignment setting (224 ) Cancel [ESC] OK [ENT] 2.

28 3. MAINTENANCE, TROUBLESHOOTING WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment. Only qualified personnel should work inside the equipment. 3.1 Preventive maintenance Regular maintenance is important for good performance. A maintenance program should be established and should include the following points. Check connectors and ground terminal on the fluxgate sensor unit and display unit for tightness. Check ground terminal for rust. Clean or replace as necessary. Check for water leakage in the interconnection cable between fluxgate unit and display unit. Clean or replace as necessary. Remove dust and dirt from the display unit and fluxgate sensor unit with a dry, soft cloth. For the LCD, wipe it carefully to prevent scratching, using tissue paper and an LCD cleaner. To remove stubborn dirt, use an LCD cleaner, wiping slowly with tissue paper so as to dissolve the dirt. Change paper frequently so the dirt will not scratch the LCD. Do not use chemical cleaners for cleaning they can remove paint and markings. Note: do not use contain chemical cleaners clean, it might help to eliminate paint and equipment will be marked. 23

29 3.2 Troubleshooting This section provides basic troubleshooting procedures which the user may follow to restore normal operation. Symptom Cannot turn on the power Heading indication changes randomly when ship is at anchor or does not change when ship moves. Heading output from KEC-30 does not appear on extermal equipment.
