[. . . ] Check that the hoist/lower switch S302 in the Motor Control Unit is set in the STOP position. 44 319568/B Start-up procedures Apply 3-phase AC power Observe the following procedure to apply 3-phase mains power to the hull unit. 1 Locate the motor protecting switch S301 in the Motor Control Unit, and check that the operating handle is pressed down to OFF position. Check that the hoist/lower switch S302 in the Motor Control Unit is set in the STOP position. Re-insert the 3-phase mains fuses for the hull unit in the ship's fuse box. Measure the three-phase voltage on the terminals E301 in the Motor Control Unit. · Write down the measured voltage here: Supply voltage: 5 Adjust the release current on the motor protecting switch S301 according to the three-phase voltage: · 230 Vac: 5, 5 A · 380/440 Vac: 4 A (minimum) Figure 18 Motor Control Unit with S301 and E301 2 3 4 HOIST REMOTE STOP LOWER S302 S301 E301 (CD015409K) 319568/B 45 Simrad SX95 Check hoist motor's 3­phase AC connections In order to ensure that the hoisting motor operates properly, and to avoid serious damage to the motor, you must check that the motor connections are made in accordance with the supplied 3­phase voltage. 1 2 3 Remove the 3-phase mains fuses for the hull unit in the vessel's fuse box. Refer to the illustration, and check if the motor connections are made in accordance with the supplied 3­phase voltage. Figure 19 Mains connection to the motor 380/440 Vac 230 Vac (CD015407A) Note The order of the connection wires must not be changed!4 5 If the connections do not match the 3­phase voltage, rewire to make them correspond to the measured voltage. Re-insert the 3-phase mains fuses for the hull unit in the vessel's fuse box. 46 319568/B Start-up procedures Check the 3­phase connection for correct rotation direction The Motor Control Unit is equipped with a Phase Watch Relay (K303), which prevents operation of the hoist/lower motor if the 3-phase connections are wrong with respect to the motor's rotation direction. Check if there is sufficient space under the keel to lower the transducer. Make sure that the flexible transducer cable is in such a position that the transducer can be lowered without stretching or hard-bending the cable. Note Watch the cable carefully during the next steps in this procedure!10 Set the hoist/lower switch S302 to LOWER position to lower the transducer all the way down. · Lowering will be stopped automatically when the top of the transducer shaft makes contact with the lower limit switch S305. · If necessary, the lowering operation can easily be stopped in any position by setting the switch S302 to STOP position. 11 Set the hoist/lower switch S302 to HOIST position to hoist the transducer back up. · Hoisting will be stopped automatically when the top of the transducer makes contact with the upper limit switch S304. · If necessary, the hoisting operation can easily be stopped in any position by setting the switch S302 to STOP position. 12 Repeat the hoist/lower operation to find the best position for a permanent fastening of the flexible transducer cable. Switch off the motor protecting switch S301 by pressing the operating handle downwards to OFF position. 13 14 The hull unit is now ready for further cabling (Ethernet cable to the transceiver unit for hoist/lower control) and system testing. The system test is provided in the relevant sonar installation manual. 50 319568/B Start-up procedures Alignment and offset adjustments When the system start-up procedure for the complete sonar system has been performed, you must acquire the alignment angle of the sonar picture and the stabilisation sensor offset. These values must be entered into the sonar system. Alignment of the sonar picture Independent of the hull unit orientation, the alignment is always defined as: · the angle measured clockwise from the bow to the 0 degrees transducer mark. [. . . ] These units will be identified as delicate in the applicable documentation. The package must then be clearly marked: Must not be transported or stored in temperatures below -5 degrees Celsius. 76 319568/B Appendix C Equipment handling Other units can normally be stored in temperatures between -30° C and +70° C, refer to the system's technical specifications for details. Unless otherwise specified, transducers must not be stored in temperatures below -20° C and above +60° C. Circuit board handling and packaging Circuit boards are delicate items. They may work year after year in an advanced product, but then fail due to a small spark of static electricity. [. . . ]
