    Main parts General description The QES 250-500 are generator sets, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The QES 250-325-400-500 operates at 50 Hz, 400V - 3 phase or at 60 Hz, 480V - 3 phase. Some parts of the unit are different, depending on which version. The QES 250-500 generator sets are driven by a fluid-cooled diesel engine, manufactured by Volvo.

This a failsafe (normally closed to battery positive) input and will immediately stop the set should the signal be removed. Removal of the battery positive supply from the emergency stop input will also remove DC supply from the Fuel and Start outputs of the controller.
  • Page 93 Display Reason OIL PRESSURE SENSOR OPEN CIRCUIT The oil pressure sensor is detected as not being present (open circuit) AUXILIARY INPUTS An active auxiliary input configured as a shutdown will cause the engine to shut down. The display shows the text as configured by the user.
  • Page 94 Electrical trips Display Reason GENERATOR HIGH CURRENT If a generator set output in excess of the high current alarm point, a warning alarm occurs. If this high current condition continues for an excess period, then the alarm escalates to either a shutdown or electrical trip condition (depending upon module configuration).
