Гирокомпас Sperry Marine NAVIGAT X MK 1

Цифровой гироскопический компас, выполнен как моноблок жестком корпусе из вспененного полиуретана. Имеет панель управления с 4-символьным дисплеем и 6 кнопками управления. При необходимости панель можно снять и расположить в удобном для работы месте. Скорость слежения составляет 100° в секунду. В штатном режиме компас работает от сети 115/230 В АС, при сбое в сети автоматически переключается на питание от аварийного источника 24 В. При сбое питания стабилизация компаса сохраняется в течение 3 минут. Двойные роторы и система жидкостного демпфирования исключает погрешность по широте. Для плавания в морях с частыми штормами разработана модификация 7. Она имеет специальную конструкцию центрующего штифта, которая дает свободу 90° при бортовой и килевой качке.

  NAVIGAT X MK 1 056343/C Safety Instructions Safety Notice Conventions The following safety notice conventions are followed throughout this manual: A Danger notice contains an operating or main- DANGER tenance procedure, practice, condition, state- ment, etc., which, if not strictly observed, will result in injury or death of personnel.

• Page 4: General Safety Information For The Operator

  WARNING After a power-up from cold, the NAVIGAT X MK 1 requires a settling time of three hours before reliable heading data is available. Power up the system at least three hours before leaving harbour.

• Page 5: General Safety Information For Service Personnel

  CAUTION The NAVIGAT X MK 1 contains electrostatic sensitive components. Electrostatic discharge may permanently damage components. When servicing the NAVIGAT X MK 1, take precautions to prevent elec- trostatic discharge. Avoid touching any of the electronic circuitry. CAUTION It cannot be guaranteed that parameter settings in the User and Setup menus and the entries made in the Magnetic Compass Calibration table are left intact when the software is exchanged.

• Page 12: Operating Principle

  056343/C NAVIGAT X MK 1 1.2 Operating Principle The north-seeking element used in the NAVIGAT X MK 1 system is the gyrosphere, a hermetically sealed unit with a funnel-shaped recess, reaching from the outer skin down to its center. Inside the gyrosphere, two mechanically linked gyroscopes are mounted with their spin axes horizontal in a carrying frame.

• Page 13: Example System Configurations

  1.3 Example System Configurations Standalone Gyrocompass/TMC System As a standalone system, the NAVIGAT X MK 1 provides North-speed error corrected true heading as well as rate of turn data. If a fluxgate sensor, type 4863, or an electronic magnetic compass is installed, the NAVIGAT X MK 1 applies magnetic variation and distrib- utes magnetic heading data to external equipment (TMC function).

  056343/C NAVIGAT X MK 1 6.5 Alignment Error Correction In order to obtain correct heading data, the existing alignment error (i.e. the angular difference between the compass orientation and the vessel’s fore-and-aft axis) must be determined and the required correction applied.

• Page 61: Magnetic Compass Calibration

  If magnetic heading is received from an already calibrated source, such as a NAVITWIN, NAVIPILOT or a self-calibrating electronic compass, cal- ibration at the NAVIGAT X MK 1 is not required and must be disabled. CAUTION The magnetic heading calibration corrects deviations due to the com- bined effects of the magnetic environment, the particular sensor being used and the receiving circuitry on the master PCB.
