AUTOMATION

Initialization After switch-on for the first time, the NAVIKNOT III Control and Display Unit will perform a self-test routine. The self-test lasts approximately 15 seconds. After the 'Self-test has been completed, the displaywill'indicate the speed as provided by the sensor selected. If an incorrect sensor has been selected or the Control and Display Unit has no sensor irwut, an audible alarm will sound and FAILUREBENSOR will be displayed. Press RESET to switch off the audible alarm. FAILURE SENSOR will remain displayed until the fault has been cleared. Before initialization can be continued, the sensor input signal must be restored or the correct sensor selected. Proceed in the following sequence to initialize the NAVIKNOT III Electrom.agnetic Speed Log System.

2.2.1- Storing the Sensitivity of the Sensor (SETUP 400) The sensitivity value of each sensor is printed on a label attached to the sensor cable.•. The sensitivity value of the sensor(s) supplied is to be stored in the SETUP mode (SETUP 400) before the calibration procedures are carried out. ' .

,. NOTE: The sensitivity values of sensors manufactured before August 1993 are given in whole numbers only over a.range.of 00 through 74. If a sensor manufactured before August 1993 is used in combination with a NAVIKNOT III system, the sensitivity value of this sensor has to be converted to suit the NAVIKNOT III operating system. Use the conversion table on page 2-3-B to convert the sensitivity value before storing it in the SETUP procedure (SETUP 4 0 0 ) . . . The sensitivity values of sensors manufactured from August 1993 onwards are given in a modified form with two decimal places over a range of 0.70 to 1.14. These sensitivity values are to be stored in the SETUP procedure (SETUP 400) without conversion. NOTE: If a sensor is changed or replaced. then,.the,sensitivity value stored in the SETUP procedure is to be changed to that of the new sensor. If the sensitivity of the new sensor is not (or cannot) be entered in the SETUP procedure (SETUP 400), then the calibration procedures are to be repeated to ensure an accurate speed display.

2.3 Calibration Procedures When the NAVIKNOT III speed log is initialized for the first time the system has to be calibrated in order to obtain accurate speed readings. 2.3.1 Calibration Values The NAVIKNOT III Control and Display Unit provides the operator with storage capacity for one zero adjustment value and a m~imum of 19 calibration values for each sensor in operation. The manufacturer recommends that the speed log system be calibrated at a minimum of three speeds: low speed, cruising speed and maximum speed. However, for maximum accuracy of speed indication over the whole speed range, the manufacturer recommends that all 19 calibration values are distributed over the complete speed range. Calibration Methods 2.3.2 There two methods which may be used to calibrate a speed log system: a) by utilizing a speed value from an accurate source (e.g. a GPS receiver) if there is no current or the speed of the current is known. b) by the traditional method of carrying out trial runs with a stopwatch over a measured distance and back again. Method a is described below in Direct Input of Calibration Values. Method b is described below in Calibration by Trial Run. Here, attention is drawn to the fact that this method is preferable when calibration is carried out in waters in which strong currents prevail because the return run will cancel out the effects of current experienced in the first run. Only one trial run is necessary if there is no current or the speed of the current is known. Enter the results of the trial runs in the forms titled Record of Trial Runs provided for this purpose in the final section.oUhis manual. Make two copies of each record. One copy is to be kept by the service station. The second copy is to be sent to C.PLATH with the List of Calibration Values, see section 2.4 of this manual. 2.3.3 Single Sensor Operation A standard feature of NAVIKNOT III is an input facility for two sensors. When, however, a vessel is equipped with only one sensor, the sensor output signal may be connected in parallel to both inputs on the NAVIKNOT III control and display unit. This configuration allows the operator to create two different calibration tables for a combination of two of the following: • Fully laden • In ballast • Deep water • Shallow water The calibration procedure is the same as described in section 2.2. Select sensor 1 for a fully laden ship, for example, and carry out the calibration procedure. At a later point in time when the ship is under ballast, repeat the calibration procedure accordingly for sensor 2. 2-8

C.PL~TH NAVIGATION· AUTOMATION

2.3.4 Zero Adjustment Zero adjustment is to be carried out before the calibration procedure and must be pertormed carefully in order to obtain maximum accuracy of the system. The zero adjustment requires the vessel be stationary in waters free of current. The example of zero adjustmen~shown below is for a deviation of 0.7 knots:

2.3.6 Calibration by Trial Run Please Note: The greater the depth of water under the keel, the greater the accuracy of the calibration. The depth of water under the vessel's keel should be at least three times its draught. The vessel's draught and trim should be the normal average. Swell, currents, heavy seas and strong winds will cause incorrect calibration. The engine speed and the course must not be varied during the test runs. Press
