Quick PCS Dual-Windlass Control-Network Diagnostics

The Challenge

Remote/proportional control was unavailable while both windlasses remained functional through local foot controls.

Work Performed

Verified local operation, inspected interfaces and GTW/VFD connections, tested M12 cabling and conductor continuity, temporarily installed a compatible termination resistor, isolated network sections, and performed repeated power-cycle tests.

Result

Local windlass operation was confirmed and the recurring Error 12 was documented as a network-level fault requiring additional authorized diagnostics.

Authorized diagnostic scope completed. The affected system was isolated and documented; additional corrective work was deferred pending separate authorization.
