18
Possible Cause
No electric power to controls.
Incorrect or incomplete wiring.
No power supply to the windlass.
Motor voltage does not match the
power supply on board.
Hydraulic relief valve not set
correctly.
The mounting bolts of the motor
are touching the motor winding.
Windlass runs but the chainwheel
stays stationary.
Chainwheel/drum keys (35) not
installed.
The motor has been overloaded
and has reached its critical
temperature.
The clutch cones are not greased.
The clutch is not fully disengaged.
Disc springs (8) not fitted.
Pawl (20) engaged.
The chainwheel not selected
correctly.
Chain twisted between windlass
and bow roller.

Solution
Make sure the isolator switch for
windlass controls is ON.
Check the fuse on power supply to
controls.
Make sure the wiring is correct and
check it for damage.
If there is more than one type of
control (pendant unit, footswitch,
helm switch), check them all in an
effort to isolate the problem.
Check the power supply to controls
from the source, step by step, and
identify the point where it stops.
Check wiring against diagrams
supplied.
Check power supply lines.
Check main isolator switch.
Check hydraulic pump.
Check name plate on the motor. If
confirmed, contact VETUS-Maxwell.
Check valve setting.
Make sure the bolts have spring
washers, adjust bolt length.
Tighten the clutch up, as described in
Section 3.2. If the problem persists,
contact VETUS-Maxwell.
Install the key.
Leave it to cool down and reset the
circuit breaker.
Disassemble the clutch cones (7),
clean and grease them as described
in Section 4.2.
Disengage the clutch fully.
Fit disc springs as described in
Section 5.3.
Disengage pawl.
Contact VETUS-Maxwell with correct
identification of the chain used on
board.
Untwist the chain.
Check the installation. If the problem
persists, some adjustments might
have to be made.
