Power Management System (PMS) · Automation & Control
ABB PMS 620 is a ship power management system (Power Distribution / Power Management System). It is normally installed within the main switchboard, automation system and machinery control network. It is intended to coordinate generator loading, starting, stopping, synchronization and load shedding to maintain electrical power continuity. The meaning of any embedded size or rating code should be confirmed in manufacturer documentation. In service it interfaces with generator controls, circuit breakers, switchboards, automation networks, load-shedding logic and alarm systems.

What our service work and the manufacturer documentation say about keeping this model running.
Review alarms and event logs, verify generator status feedback, load sharing, synchronization permissives and automatic start/stop logic under approved test conditions. Inspect redundant power supplies, network connections and controller health and confirm that manual fallback remains available. Exact trip thresholds and protection settings must be taken from approved vessel and manufacturer documentation.
Critical spares may include controller modules, power supplies, communication interfaces, I/O modules, fuses and selected sensors according to the vessel's automation critical-spares list.
