Checking manual raise/lower of transducer with hand
crank
Perform this check after all wiring has been completed. Ship’s mains power must
applied to the hull unit, otherwise the magnetic brake of the raise/lower motor
activates, disabling the manual raise/lower gears.
1. Turn off the breaker on the hull unit.
2. Detach the brake-off switch cover.
3. Set hand crank to the screw shaft gear and turn it while pressing the brake-off
switch.
4. The transducer should rise/lower smoothly with even force in upper to lower
limits. If not, the centers of the main body flange and the retraction tank are
not aligned. Adjust the hull mounting position if necessary.
