Simrad SP90NoteCleaning the transducerThe transducer normally needs little attention. However, thetransducer face should be inspected and cleaned when docking.To lower the transducer when in dock, use the hoist/lower switchS302 in the Motor Control Unit (mounted on the gantry). Set theswitch to STOP to position the transducer at any vertical location.Do not use strong solvents, but a normal synthetic soap and water.Marine growth must be carefully removed with fine-gradesandpaper or emery paper.The transducer face must not be painted.Motor overload switchTo prevent the hoist/lower motor from overload, an overloadcircuit breaker S301 is located in the Motor Control Unit. This mayautomatically be switched off during hoisting if the vessel’s speedis too high, or if the transducer shaft has been bent.To reset the motor overload switch, open the Motor Control Unit,locate the switch S301 and press the button marked 1.→ The circuit breaker is shown on figure 20 on page 151.Hoisting and lowering the transducer fromthe Sonar RoomIn case of a failure in the normal hoist/lower operation controlledfrom the Sonar Operating Panel, the transducer may be hoisted andlowered from the Sonar Room. Three different procedures may beused.CautionLocal control switch S302If the 3-phase voltage for the hoist/lower motor and the +24 Vdcstand-by voltage from the Transceiver Unit are available, thetransducer can be hoisted or lowered by switch S302 in the MotorControl Unit. The motor will automatically stop when thetransducer shaft reaches the upper or lower limit switch.Remember to set the switch back to Remote position whenfinished.Hoist/lower contactors K301 and K302If the 3-phase voltage for the hoist/lower motor is available, thetransducer can be hoisted and lowered by operating the hoist(K301)andlower(K302) contactors in the Motor Control Unit byactivating the small switch handle on the front of the contactor.The switches must be released before the transducer shaftreaches upper or lower position, as this operation overrides thetwo limit switches.152 850--164511 / B
MaintenancesManual hoist and lower operationIf the 3-phase voltage is not available, the transducer must behoisted and lowered by means of the hand crank. Observe thefollowing procedure.1 Locate the motor overload switch S301 in the Motor ControlUnit, and press the red button marked 0.2 Locate the hand crank in the Motor Control Unit.3 Remove the plastic plug on the top cover of the Hull Unit,and mount the hand crank onto the stub shaft through thehole in the top cover.4 Locate the brake release screw on the motor. Use an Allenkey to tighten up the screw until the motor brake is released.Approximately 2 - 3 turns clockwise are required.→ The location of the brake release screw is indicated in figure20 on page 151.5 Use the hand crank to hoist and lower the transducer.6 When finished, loosen the brake release screw to engage themotor brake. Check with the hand crank to ensure that themotor brake is engaged.7 Remove the hand crank from the stub shaft, and mount it inits storage position in the Motor Control Unit.8 Press the black button marked 1 on the motor overloadswitch S301.Air bleedingTo avoid damage to the transducer by transmitting in air inside thetrunk, the air bleeding system must be checked after the ship hasbeen docked.Observe the following procedure.1 Close the air bleeding cock on top of the trunk flange anddismount the pipe.2 Open the air bleeding cock and check that the water ispassing freely through the cock.3 Check that the pipe is open by blowing in one of the pipeterminations.4 Remount the pipe to the air bleeding cock and turn the cockto the open position.850--164511 / B153
