From the supplied front-panel image, the product is identified as:
The front panel clearly shows that the unit is built for main engine safety monitoring with dedicated sections for Shutdown, Slow Down, Alarm, RPM Levels, RPM Detector Systems, Reset, and Commissioning / parameter adjustment. Archived Norcontrol documentation describes the SSU 8810 as a Safety System Unit designed to monitor a ship’s main engine and its RPM, and to control safety functions such as shutdown and slowdown if monitored values exceed defined limits.
The Norcontrol SSU 8810 Safety System Unit is a dedicated marine engine protection controller designed to safeguard the ship’s main propulsion engine against dangerous operating conditions. Onboard a vessel, the main engine must be continuously monitored for critical parameters such as lubricating oil pressure, bearing temperature, piston cooling performance, cooling water condition, exhaust temperature, and overspeed. If one of these parameters moves outside its safe operating range, the safety system must react immediately and in the correct way. That is the role of the SSU 8810.
In practical marine service, the SSU 8810 works as a central protection panel between field sensors and the engine control system. It receives signals from pressure switches, temperature switches, RPM detectors, emergency stop circuits, and related safety contacts. Based on programmed logic, it can issue an alarm, activate slowdown, or execute a full shutdown of the main engine. This layered response is important because some faults require controlled engine load reduction first, while others demand immediate stop action to prevent severe machinery damage.
The Norcontrol SSU 8810 is used in marine propulsion safety systems where the main engine requires automatic protection against unsafe operating conditions. Typical applications include:
It may interface with:
Because the SSU 8810 is a specialized main engine safety controller, spare parts and technical support are important when a vessel faces repeated shutdown alarms, faulty slowdown logic, display issues, or RPM detector faults. Market listings also confirm the unit as Norcontrol SSU 8810 Safety System Unit, often referenced with P/N 8200049 in the marine spare-parts market.
