j Writemeasuredthree--phasevoltagehere:.......................

j The hoist/lower motor is preconnected for 380V/440V

three--phase. If the measured three--phase voltage is

230V, the motor has to be reconnected. Remove the cover

forthe mainsconnectiononthe motor,andrefer tofigure

4 to link the motor connections to correspond to the

measured voltage.

j Adjust the release current of the motor overload switch

S301 according to the three--phase voltage:

230V: 2.4 A

380/440V: 1.6 A

j Remove the hand crank from its storage position.

j Set the motor overload switch to normal position by

pressing the black button marked ”1”.

j Set the hoisting/lowering switch S302 to LOWER.

j Check the training direction of the hoisting/lowering

motor by briefly pressing the hand crank safety switch

S303.

j Ifthetransducer shaftwashoisted,disconnectthe ship’s

S301. Reinsert the three--phase mains fuses.

j Set the hoisting/lowering switch S302 to STOP.

j Putthethe hand crankbacktoits storage position inthe

motor control unit.

j Checkifthere is sufficientspaceto lower thetransducer.

j Makesure thattheflexibletransducercables areinsuch

a position that the transducer can be lowered without

stretching or hard--bending the cables. Watch this

carefully during the next steps in this procedure.

j Set the hoisting/lowering switch S302 toLOWERforfull

lowering of the transducer. The lowering will

automatically stop when the top of the transducer shaft

hits the lower limit switch S305.

j Make a preliminary fastening of the flexible transducer

cables and watch the cables during the hoisting in the

next step.
