The GSC+ is designed to operate when the GSC+ is powered by 24 DCV. The GSC+ will also power up when the GSC+ is powered by 32 DCV. The GSC+ monitors many of the functions of the generator set. The GSC+ controls many of the functions of the generator set. The functions and features of the GSC+ are listed below.
The GSC+ provides the generator AC output information. The information includes the metering of power. The GSC+ controls starting and stopping of the engine.
The GSC+ shows engine conditions and generator output information on two displays.
The displays show the fault codes. The displays also show the information for programming that is used by the GSC+.
The GSC+ monitors the system for faults. If a fault occurs, the GSC+ performs a controlled fault shutdown. The GSC+ begins to provide annunciation of the fault alarm. The GSC+ uses indicators and displays in order to describe the fault to the operator or the service technician.
The GSC+ contains programmable features for certain applications. The programmable features are also used by the GSC+ in order to meet the requirements of the customers.Note: Setting P023 to 0 ensures proper operation on MUI engines. Failure to set setpoint P023 can result in improper engine operation, incorrect display of engine parameters, and logging an erroneous CID 590 fault. For more information on the P023 setpoint and other GSC+ setpoints, see Systems Operation, "Engine-Generator Programming OP5-0".____________________GSC+ Part Number

Location Of GSC+ Part NumberRear View Of GSC+The part number is stamped into the rear housing of every GSC+ above the harness connector. When the GSC+ is updated internally, the part number also changes. The part number can be used to identify the effectivity of any changes.GSC+ Serial Number

Location Of GSC+ Serial NumberRear View Of GSC+The serial number of the GSC+ is a ten digit number which is unique for each GSC+. The preceding illustration shows the location of the serial number on the back of the GSC+. The serial number is also shown to service personnel when the GSC+ is in option OP2-2. The serial number which is shown on the display and the actual serial number will always match. See Systems Operation, "AC Factory Calibration Setpoint Viewing OP2-2".Fault Indicators
The ten fault indicators are used in order to show a fault that is present. The ten fault indicators are also used to describe a fault that is present. The fault indicators are divided into four groups. The four groups are the fault alarm indicator (4), the spare fault indicators (2), the fault shutdown indicator (3) and the dedicated shutdown indicators (1) .The yellow fault alarm indicator (4) FLASHES when the GSC+ detects a fault that is an alarm fault. The alarm fault does not cause the engine status to change. The engine is able to start. The engine will continue operating, only if the engine is running at the time of the alarm fault. Fault alarm indicator (4) is accompanied by an alarm fault code that is shown on upper display (5) when the alarm codes key is pressed.The red fault shutdown indicator (3) FLASHES when the GSC+ detects a fault that is a shutdown fault. The engine is shutdown if the engine is running and the engine is not allowed to start. Fault shutdown indicator (3) is accompanied by a fault code that is immediately shown on the upper display (5) .The yellow spare fault indicators (2) FLASH when the conditions that are associated with that spare fault are active. The three spare faults can be programmed to show coolant loss, oil temperature, spare fault condition or no assignment. The spare fault condition may be a customer generated switch input. See Systems Operation, "SP Fault Codes" for more information. The yellow fault alarm indicator (4) or the red fault shutdown indicator (3) will accompany the spare fault indicators (2). The spare fault indicators will tell whether the spare fault input is programmed to be an alarm condition or a shutdown condition.The red dedicated shutdown indicators (1) represent the following shutdown faults: low oil pressure, emergency stop, high water temperature, engine overspeed and engine overcrank. When the GSC+ detects a fault in one of these areas, the dedicated shutdown indicator (that corresponds to the fault) FLASHES. The engine is shutdown if the engine is running, and the engine is not allowed to start. No fault codes are associated with the dedicated shutdown indicators because each indicator has a descriptive label.Many of the dedicated shutdown faults depend on certain setpoints in the GSC+. See Systems Operation, "Setpoint Programming OP5" for more information. To restart the engine after a shutdown, see Systems Operation, "Shutdown Mode".The conditions that are required to activate the dedicated fault shutdowns are in the following list. The results of each dedicated fault are in the following list.____________________Low Oil Pressure - The engine oil pressure drops below the setpoints for low oil pressure shutdown that are programmed into the GSC+. There are two low oil pressure setpoints. One setpoint is used when the engine is at idle speed. The other setpoint is used when the engine is at rated speed. When a low oil pressure fault occurs, the low oil pressure indicator FLASHES, and the engine is shut down. The engine is not allowed to start until the fault is corrected.Emergency Stop - The operator presses the emergency stop push button (ESPB) on the front panel. When an emergency stop condition occurs, the emergency stop indicator FLASHES and the engine is shut down. The engine is not allowed to start until the condition is corrected.High Water Temperature - The engine coolant temperature rises above the setpoint for high water temperature shutdown that is programmed into the GSC+. When the high water temperature fault
