3 Trends Monitoring Screen The Trends screen displays up to 8 different values in real-time monitoring. These value selections are customizable to meet various troubleshooting and monitoring situations. ata is stored in internal controller memory or a USB drive and can be easily exported and imported. Binary Input and Output Screen The Binary Input and Output screen displays a comprehensive view of the status of all the inputs and outputs. AlarmList Screen The AlarmList screen displays up to 16 shutdowns, warnings, and engine messages in a color coded list. Features include an alarm summary at the bottom of the AlarmList screen and an alarm alert on any of the metering screens. Synchroscope (Paralleling) Screen The Paralleling screen displays the key parameters to allow for generators to synchronize together. The Paralleling screen provides a comprehensive view of critical parameters to aid in easily adjusting paralleling system settings. History Screen The History screen displays up to 4000 events, warnings, and shutdowns with the reason, date, time, and critical system parameters. This extensive event history allows for detailed analysis of reoccurring faults. G /18b Page 3

5 Controller Functions The following chart shows which functions cause a warning or shutdown. Most functions are available as outputs. Warning shows a yellow text message on the digital display and sounds the alarm horn signaling an impending problem. Shutdown shows a red text message on the digital display, sounds the alarm horn, and stops the generator set. Standard functions * Requires additional equipment or input signals, supplied by or specified by the customer Status Event or Fault Overspeed Over voltage shutdown Over frequency warning Under frequency warning High oil temp warning Battery over voltage warning Battery under voltage warning Generator voltage unbalanced warning Generator current unbalanced warning High oil temp shutdown High coolant temp warning High coolant temp shutdown Low coolant temp warning High air/fuel mix temp warning High air/fuel mix temp shutdown High exhaust temp shutdown erate active Over power shutdown Reverse power Reverse vars / loss of excitation Low oil pressure shutdown Low oil pressure warning Low water pressure warning Low Oil Level Shutdown High Oil Level Warning Low Fuel Pressure Warning High Fuel Pressure Shutdown Auxiliary igital Fault Shutdown Immediate * Auxiliary igital Fault Shutdown Slow Cooldown * Auxiliary igital Warning Running Only * Auxiliary igital Warning Any time / Always * igital Low Coolant Level Shutdown * igital Ground Fault Warning * Generator Not In Auto Alarm Generator Not Ready Alarm Fuel Valve Fail To Open Warning Fuel Valve Fail To Close Shutdown Over Current Warning Over Current Shutdown High Exhaust Temperature Shutdown to High Exhaust Temperature Warning Warning Function Shutdown Function G /18b Page 5
