5 Compass 1 Description 1.1 Application The TMC--Converter (TMC = Transmitting Magnetic Compass) for transmitting the course information to the repeater compasses or other nautical signal loads. The TMC--Converter is suitable for: -- ships under 500 gross tons, which need no gyro compass but want an electrical heading input for the autopilot and want a heading input for the compass repeaters. -- ships, which need, additional to a gyro compass, an independent magnetic compass system to transmit compass information to a heading repeater (for example ships under Dutch flag). The TMC--Converter, type reads the heading data from a connected magnetic sonde and disposes it, at in total 5 outputs, to connected heading receivers: -- 2 outputs (adjustable) as NMEA 0183 or Course bus NMEA --dataformat adjustable for 2 different transmission rates outputs as Step--Signal with 6 /Step, 35VDC Magnetic compass 24VDC Magnetic sonde Typ TMC -Converter VDC or Heading receivers 3 x Step--Signal 6 /Step 35VDC 2 x NMEA or Corse bus Alarm (System Alarm and Sensor Alarm) Fig. 1: TMC--Converter, type NG001 Edition: July 9, DOC010002

6 1.2 Technical Data Mechanical Data Dimensions, weight and protection see Dimensional Drawing HP Electrical Data Supply voltage: Power consumption: 24VDC max. 10W (w/o connected receiver) Input signal Heading signal from magnetic sonde (R1,R2, S1, S2 und S3) Outputs: 2x NMEA/Course bus Alarm contacts (galvanically separated) 3x Step--signal ( 6 /Step, 35VDC/max. 10W) The outputs are protected separately: NMEA/Course bus with 1,0A T, 250V each Step--output with 0,25A T, 250V each DOC Edition: July 9, 2004

7 Compass 2 Operating There are no operating elements at the TMC--Converter type NG001. After switching ON of the supply voltage of 24VDC the Converter is in operation. To configurate the outputs,see section 3.3. Edition: July 9, DOC010002

8 3 Installation of the TMC -Converter 3.1 Mounting of the TMC -Converter The TMC--Converter should be mounted at a location where shocks and vibrations are minimal. The mounting should be performed in that manner, that there are no influences of seastate. The TMC--Converter should be installed under consideration of Dimensional Drawing HP005. The frontcover should be removable after installation. Referring to the internal protection at the dimensional drawing should be observed DOC Edition: July 9, 2004

9 Compass 3.2 Establishing of cable connections General remarks Caution When establishing cable connections ensure that the cables are disconnected from the power supply. It is essential to ensure that all cables are disconnected from the power supply, if necessary measure the voltage beforehand and/or disconnect the relevant distributor. In order to ensure that the converter operates correctly, it is essential that you follow the procedures described below for establishing cable connections. -- Strip approx. 180 mm of the cable. (Depending from the distance of the cable inlet to the connection terminal) Make sure you do not damage the shielding layer. -- Strip off the shielding to a remainder of approximately 15mm. approx. 15mm approx. 180mm Fig. 2: How to strip the connection cable -- Screw the cable gland out from respective housing and push the screw connection components over the cable. It is absolutely essential that the sequence (as shown in Fig. 3) is adhered to. -- check the cone and counterpart on the earthing insert for corrosion and if necessary remove corrosion using an appropriate process (emery board). -- Push the counterpart of the earthing insert as far as the end of the cable shield. Edition: July 9, DOC010002

10 -- Push the earthing insert cone below the shielding against the counterpart. Observe a shared evenly distribution of the shielding via the cone (see Fig. 3). Wall and DIN socket Shielding Cable Counter nut Earthing insert - Cone - Counterpart Seal + strain relief Washer Fig. 3: Making the cable entry -- Insert the earthing insert, the seal with and the washer into the cable gland, place the counter nut on top and and hand--tighten. -- Strip the cable cores to a length of approx. 15 mm, twist slightly and clamp on the cable end sleeves. Connect the cable strands in the respective housing as shown in the respective table. Hand--tighten the terminal screws concerned. -- Check the connection is firm by pulling lightly DOC Edition: July 9, 2004

11 Compass General information about establishing an earth connection In order to comply with stringent EMC requirement, please abide by the information given below regarding cable connections. Use the cable types specified. It is essential to ensure that these connections have a common reference to ship s eart! Any additional components (options) must also be connected to the common earth! Fig. 4: Example for establishing an earth connection All earth connections must be made as shown in Fig. 4. The earthing cable must possess a cross--section of minimum 1,5mm 2. The cable bracket should be mounted between two toothed discs. Earth connections must be free of corrosion and well fastened. Edition: July 9, DOC010002

16 4 Maintenance and Repair 4.1 Maintenance The TMC--Converter is maintenance free Alignment (sensitivity of magnetic sonde) Basic status: -- TMC--Converter is installed. -- Magnetic compass is installed together with the magnetic sonde. -- Magnetic compass is connected to the TMC--Converter. -- Heading repeater is connected. -- Data format is adjusted (NMEA or Course bus) After applying the supply voltage(s) the heading repeater synchronizes at its 0 --position and turns after that to the true heading value. If the heading display from the heading receiver is differing from the heading from the magnetic compass, the screws of the magnetic sonde must be loosened and the magnetic sonde has to be turned within its mounting until both heading values correspond. Alignment: (see Fig. 8) At headings of North, East, South and West voltages have to be measured at the test--points TP11 and TO 12 and have to be aligned with a potentiometer to a value according to below mentioned table. Heading of magnetic compass Test -point Potentiometer voltage to be aligned 0 3 TP12 R155 4,3VDC 0,1VDC TP12 R155 0,7VDC 0,1VDC 90 3 TP11 R155 4,3VDC 0,1VDC TP11 R155 0,7VDC 0,1VDC The potentiometer R113 is pre--aligned by the company, but if there is a higher deviation at the 45 intermediate--values, than the heading value of the connected heading receiver has to be adapted with potentiometer R DOC Edition: July 9, 2004
