Marine Main Engine Electronic Board Repairs
Diagnostics • PCB Repairs • Signal Verification • Technical Support
AUTOMATOS KOSMOS 4U provides diagnostic and repair services for electronic boards and control modules used in marine main engine installations.
We support legacy and modern systems, assessing both the electronic board and its interaction with sensors, operator controls and connected equipment. Our objective is to identify the underlying cause of the fault and restore operation wherever repair is technically feasible.
⚓ Boards & Modules We Support
✅ Main engine control and start–stop sequence boards.
✅ Electronic governor modules and actuator driver boards.
✅ Speed signal processing boards for magnetic pickup sensors.
✅ Input/output modules and analogue signal processing boards.
✅ Monitoring, alarm and protection circuit boards.
✅ Power supplies, amplifiers, converters and interface modules.
⚓ Component-Level Diagnostics & Repairs
We perform visual inspections, electrical measurements and circuit-level investigation to locate defective components.
✅ Power supply and voltage regulation checks.
✅ Diagnosis of short circuits, overheating and intermittent faults.
✅ Testing of electronic components, relays and output stages.
✅ Repair of defective solder joints, connections and PCB tracks where feasible.
✅ Replacement of faulty components and post-repair testing.
⚓ Verification within the Installation
An electronic module malfunction may originate from external signals, wiring or connected equipment. We therefore also assess the board’s operating conditions.
✅ Verification of sensor, command and feedback signals.
✅ Inspection of wiring, connectors and power supplies.
✅ Checks of interfaces with governors, actuators and monitoring systems.
✅ Functional testing and readjustment where required.
The available tests depend on the module type, technical documentation and access to suitable bench or onboard testing conditions.
