1.3 The SensorsThe choice of a sensor, whether flush-mounted or of the blade type, mainly depends on the operationaldemands made on the vessel and the installation posnion of the sensor in the ships bottom. The flush-mounted sensor is reccmmended for ships operating in shallow water, because this type of sensor is lesslikely to sustain damage. On the other hand, however, the flush-mounted sensor, in cemparison with theblade type, is more susceptible to fouling, which innibits the flow of water over the electrodes.The use of the blade-type sensor is recommended for all ships not operating in shallow water.The main factor governing the location of the sensor is the boundary layer. a wedge-shaped mass ofwater drawn along by the ship's hull. The boundary layer is several millimeters thick at the bow and canexpand to one meter at the stem. Since the sensor must be located outside the boundary layer, the f1ush-mounted sensor must be installed as far forward as possible. The length of the blade-type sensor allowsit to be extended beyond the boundary layer and is accordingly free from this restriction. The idealloca-tion for the blade-type sensor is as close as possible to the centre of longitudinal and lateral osdllations.When a blade-type sensor is to be frtted at a retatively inaccessible posnion, C.PLATH recommends theNAVIKNOT III PN System. The PN System includes a pneumatic sensor raising and lowering unit, whichis operated from the master central unit

NAVIKNOT III N is the C.PLATH standard electro-magnetic log system employing the blade-type sen-sor, which may be installed at the most cenvenientlocation in view of the few limitations with regard tothe boundary layer. The blade-type sensor may beraised and lowered manually.Speed range: -5 kts to +25 kts.

NAVIKNOT III PN is basically identical to the III Nversion with the exception that the blade-type sensoris raised and lowered pneumatically. Control of thepneumatic raising and lowering installation is carriedout on the Main Control and Display Unn on thebridge. Sensor location is the same as for the III Nversion.Speed range: -5 kts to +25 kts.

NAVIKNOT III NF is the electromagnetic log systemwith the flush-fitted sensor. The advantage of thistype of sensOr is that it will not be damaged whenshallow waters are encoumered. In view of the nega-tive influences at the boundary layer the tlush-fitted

.. ' sensor may only be installed in the foremost part ofthe bow.Speed range: -5 kts to +25 kts.

NAVIKNOT III N Yacht NAVIKNOT III N YACHT is a ccmpact version of thestandard III N version and has been designed forapplication on smaller vessels such as yachts andfishing craft where space is at a premium and lightweight and small size play a large part. The blade-type sensor can be raised and lowered manually.Speed range: - 5 kts to + 25 kts.

25 Knofs NAVIKNOT III FNF 25 Knots is a special space-saving version of fhe NF f1ush-fl\led sensor. Thesensor is permanently bolted fo the hull and is onlyreccmmended when regular removal of fouling ispossible without drydocking. This type of sensorsurtable for application on steel, aluminium, glass-fiber and wooden hulls. 11 necessary, the sensor canbe replaced without drydocking.Speed range: -5 kfs to +25 kts.

35 Knots NAVIKNOT III FNF 35 Knots is a flush-fitted sensorequipped wrth an external hydrofairing to smooth theflow of the water at high speed across the head ofthesensor. The sensor is permanently bolted to the hulland is only recommended when regular removal of

. fouling is possible without drydocking. This sensor issurtable for application on steel, aluminium, glass-fiber and wooden hulls. If necessary, the sensor canbe replaced without dry docking.Speed range: - 5 kts to + 35 kts.

50 - BO Knots NAVIKNOT III FNF 50 and 80 Knots represent aseries of sensors bui~ for high speed ranges of - 5ktsto + 50 kts and -5 kts to +80 kts. Similar to the otherFNF sensors, these are also permanently fixed totheship's hull and each is equipped with a hydrofairing.These sensors are only reccmmended where regularremoval of fouling can be carried out without drydock-ing, and are suitable for hulls of steel, aluminium,glass fiber and wood. When required, a sensor canbe replaced without drydocking.

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 (SETUP400) before the calibration procedures are carried out. ' .

,.

NOTE: The sensitivity values of sensors manufactured before August 1993 are given inwhole numbers only over a.range.of 00 through 74. If a sensor manufactured before Au-gust 1993 is used in combination with a NAVIKNOT III system, the sensitivity value of thissensor has to be converted to suit the NAVIKNOT III operating system. Use the conversiontable on page 2-3-B to convert the sensitivity value before storing it in the SETUP procedure(SETUP400)...

The sensitivity values of sensors manufactured from August 1993 onwards are given in amodified form with two decimal places over a range of 0.70 to 1.14. These sensitivity valuesare 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 SETUPprocedure is to be changed to that of the new sensor. If the sensitivity of the new sensor isnot (or cannot) be entered in the SETUP procedure (SETUP 400), then the calibration pro-cedures are to be repeated to ensure an accurate speed display.

I4\!Ic. PL.A.T H.'1 NAVIGATION' AUTOMATION2.3 Calibration ProceduresWhen the NAVIKNOT III speed log is initialized for the first time the system has to becalibrated in order to obtain accurate speed readings.

2.3.1 Calibration ValuesThe NAVIKNOT III Control and Display Unit provides the operator with storage capacity forone zero adjustment value and a m~imum of 19 calibration values for each sensor inoperation.The manufacturer recommends that the speed log system be calibrated at a minimum ofthree speeds: low speed, cruising speed and maximum speed. However, for maximumaccuracy of speed indication over the whole speed range, the manufacturer recommendsthat all 19 calibration values are distributed over the complete speed range.

2.3.2 Calibration MethodsThere 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 nocurrent or the speed of the current is known.

b) by the traditional method of carrying out trial runs with a stopwatch over a measureddistance 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 factthat this method is preferable when calibration is carried out in waters in which strong cur-rents prevail because the return run will cancel out the effects of current experienced in thefirst run. Only one trial run is necessary if there is no current or the speed of the current isknown.

Enter the results of the trial runs in the forms titled Record of Trial Runs provided for thispurpose in the final section.oUhis manual. Make two copies of each record. One copy is tobe kept by the service station. The second copy is to be sent to C.PLATH with the List ofCalibration Values, see section 2.4 of this manual.

2.3.3 Single Sensor OperationA 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 beconnected 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 combi-nation 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 fullyladen ship, for example, and carry out the calibration procedure. At a later point in time whenthe ship is under ballast, repeat the calibration procedure accordingly for sensor 2.

C.PL~TH~ NAVIGATION AUTOMATION2.3.4 Zero AdjustmentZero adjustment is to be carried out before the calibration procedure and must be pertormed carefully inorder to obtain maximum accuracy of the system.

Replacement of the Control and Display Unit

Before the NAVIKNOT III control and display unit can be removed from its housingor bridge console, it must be made certain that the information stored in the EPROMduring initialization is available for transfer to the replacement control and displayunit. This information comprises the data recorded in the in the SETUP TABLE, see2.2, and the calibration values stored in the internal calibration value table, see 2.3.The calibration values should also be recorded in the List of Calibration Values, see2.4. If this information has not been recorded in the above mentioned lists, it is to becopied from the defective control and display unifbefore it is replaced. If this is notpossible (because of a defective display e.g.) a solution may be found in removingthe EEPROM from the defective unit and installing it in the replacement unit.The EEPROM is located on the middle PCB.If none of these procedures as described above are possible, the replacementcontrol and display unit will have to be initialized from scratch including the calibra-tion procedure.

Replacement Procedure

1. Compare the information and parameters stored in the control and display unitwith that in the SETUP TABLE, see 2.2. Correct data in the SETUP TABLEwhen necessary.

2. Compare the calibration values stored in the control and display unit with thevalues in the List of Calibration Values, see 2.4. Correct values in the List ofCalibration Values when necessary.

3. De-energize the NAVIKNOT III speed log system.4. Remove the control and display unit from its console frame or housing.5. Disconnect the two plug connectors at the back of the control and display unit.6. Set the dip switches on the replacement control and display unit to ihe same

positions as on the unit being replaced, see also sections 3.1, 3.2 and 3.3 ofthis manual.

7. Connect the two plug connectors to the replacement control and display unit.8. Install the replacement control and display unit in its console frameor housing.9. Energize the NAVIKNOT III speed log system.10. Refer to section 2.2 The SETUP TABLE and Initialization of this manual and

initialize the replacement control and display unit by entering the setup informat-ion contained in the setup table.
