Page 3 NAVIKNOT 600 SE 056349/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 CAUTION The NAVIKNOT 600 SE is type approved as a speed and distance meas- uring equipment only. While the satellite PCB contained in the NAVIKNOT 600 SE electronics unit produces position, heading and rate of turn data, these data are to be regarded internal and may not be used for navigation purposes.

In accordance with the mutual recognition agreement (MRA), USCG approval no. 165.10/EC 0801/4477207has been granted. A basic system consists of the NAVIKNOT 600 SE Electronics Unit, a Control and Display Unit (CDU), a satellite antenna unit and an EM (elec- tromagnetic) speed sensor with the Preamplifier E, type 2863.
Page 10: Data Outputs
056349/C NAVIKNOT 600 SE Data Outputs Serial speed and distance data is provided in the NMEA 0183 format at six RS-422 outputs. These are divided into two groups of three outputs each, which may be configured independently to suit the receiving equipment.
Page 11: Operating Principle
NAVIKNOT 600 SE 056349/C 1.2 Operating Principle To determine the longitudinal and transverse ground speeds, the sys- tem makes use of a self-contained satellite sensing system, consisting of the satellite PCB with two GPS receivers inside the electronics unit and the antenna unit connected to it.

056349/C NAVIKNOT 600 SE Service Setup – Parameters Analog Output Configures the analogue speed outputs (voltage and current output). Source Selects the data source for the analogue outputs. Setting: The outputs provide the actual speed over ground The outputs provide the actual speed through the water Voltage Configures the analogue output voltage range.
Page 65 NAVIKNOT 600 SE 056349/C Current Configures the analogue output current range. The output current range is defined by two pairs of values: The minimum speed and associated minimum current determine the lower limit of the output range, while the maximum speed and associ- ated maximum current define its upper limit.
Page 66: Pulse Output
This signal, a 100 ms pulse, is used to mute the audible alarm indication at a central alarm facility when the respective alarm is acknowledged locally at the NAVIKNOT 600 SE CDU. Pulse Output 1–3 Configures group 1 of the pulse outputs (outputs 1 – 3).
Page 67 NAVIKNOT 600 SE 056349/C Pulse Output 4–5 Configures group 2 of the pulse outputs (outputs 4– 5). Pulse/NM Selects the output pulse frequency. Setting: 10 Pulse/NM The output delivers 10 pulses per nautical mile. 100 Pulse/NM The output delivers 100 pulses per nautical mile.
Page 68 20000 Pulse/NM The output delivers 20000 pulses per nautical mile. MUTE RELAY When an alarm is acknowledged locally at the NAVIKNOT 600 SE CDU, the output delivers a pulse to mute the audible alarm indication at a central alarm facility. Source Selects the data source for pulse output 6.
Page 69: Output 1-3
Messages Selects the NMEA sentences to transmit. If the NAVIKNOT 600 SE cannot provide valid data for an NMEA sen- tence field, a null field (empty field) is sent. Status fields for invalid or unknown data are marked invalid (“V“). Other sentences than those described below must not be activated for the NAVIKNOT 600 SE.
Page 70 056349/C NAVIKNOT 600 SE Data Logger Puts the output into a special data logging mode. This option is intended for test purposes only and must never be acti- vated during normal operation. If the logging mode is made active, the serial data outputs 1–3 do no longer provide regular NMEA data.

Page 82 Sets the correction values (“deltas”) to compensate for existing offsets of the heading sources relative to the vessel’s fore-and-aft line. As only the GPS source is used within the NAVIKNOT 600 SE system, a delta value must be entered for the GPS source only. This compensates for misalignment of the GPS antenna support with the vessel’s fore-and-...
Page 83 Calibrates the magnetic heading sensor on the satellite PCB. The magnetic heading sensor contained on the satellite PCB is not suita- ble for use within the NAVIKNOT 600 SE system. Therefore it must not be calibrated. Do not carry out the Mag. at Sea Cal. procedure. Leaving the sensor in the uncalibrated state will prevent it from being activated by accident.

Page 85: Chapter 7: Em Sensor Calibration
056349/C Chapter 7: EM Sensor Calibration Once the NAVIKNOT 600 SE system has been installed and the basic configuration carried out, the EM sensor must be calibrated to make sure that the system’s water speed and distance outputs meet the speci- fied accuracy.
Page 86: Sensor Calibration
7.2 Sensor Calibration To minimize the deviation between the vessel’s actual water speed and the speed displayed and transmitted, the NAVIKNOT 600 SE stores sen- sor-specific calibration data in a so-called calibration table. The calibration table holds up to 21 entries, so-called calibration points, each of which consist of an uncalibrated and a corresponding true water speed value.
Page 87: Editing The Calibration Table Directly
NAVIKNOT 600 SE 056349/C Editing the Calibration Table Directly To add, edit or delete calibration points directly, go to page 2 of the Service Setup and select the Calibration | Cal.Table sub-menu. The data stored at calibration point no. 00 is shown (dashes will appear if the table is empty).

Page 89: Automatic Entry
NAVIKNOT 600 SE 056349/C Automatic Entry With the automatic entry method, the required zero point setting is determined automatically. Automatic entry may only be used when the vessel is stationary in waters free of current, i.e., if the actual water speed is known to be zero.
Page 90: Calibration By Trial Runs
However, as the NAVIKNOT 600 SE obtains the vessel’s current position from the sattelite PCB, it is equally acceptable to start the run clock at a given point in time and to stop it as soon as a distance of at least one mile has been traversed.
Page 91: Two Way Trial Run
NAVIKNOT 600 SE 056349/C Two Way Trial Run Note During a two way trial run, the vessel’s heading during runs A and B should ideally be parallel to the direction of the effective drift, as the drift component perpendicular to the heading cannot be compensated for.

Page 93: One Way Trial Run
NAVIKNOT 600 SE 056349/C One Way Trial Run Note In a one way trial run, any drift due to wind and/or current will adversely affect the calibration. Conducting a one way trial run in the presence of drift, may degrade instead of improve the speed accuracy.

NAVIKNOT 600 SE 056349/C 8.2 EM Sensor and Preamplifier Malfunction of the EM sensor, resulting in a “Sensor1 Failure” alarm being given, may be caused by a mechanical or electrical defect in the sensor or by a defective preamplifier. As the preamplifier contains no built-in test circuitry, only a basic electrical check is possible in the field.
