Other
• Priming
• Temperature-controlled start & stop
Control types
• Power management system (PMS) control
◦ AUTO mode
◦ SEMI mode
• Switchboard control
◦ Operator controls the system from the switchboard
◦ Only the controller protections are active
Control modes
• AUTO mode
◦ Automatic power management
◦ Automatic load-dependent genset start & stop
◦ Automatic synchronisation & de-loading, and breaker control
• SEMI mode
◦ Operations only on operator command
◦ Operator-initiated synchronisation and de-loading
◦ Display unit push-buttons for genset start & stop, breaker open & close, and 1st priority
