Adjust the release current of the motor overload switch
S301 according to the three--phase voltage:
230V: 2.4 A
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
for the mains connection on the motor, and refer to figure
4 to link the motor connections to correspond to the
measured voltage.
380/440V: 1.6 A

Set the hoisting/lowering switch S302 to LOWER for full
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.
Set the motor overload switch to normal position by
pressing the black button marked ”1”.
Check the training direction of the hoisting/lowering
motor by briefly pressing the hand crank safety switch
S303.
Put the the hand crank back to its storage position in the
motor control unit.
Make sure that the flexible transducer cables are in such
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.
