Display Area Of Generator Set Control + (GSC+) (1) Dedicated shutdown indicators (2) Spare fault indicators (3) Fault shutdown indicator (4) Fault alarm indicator (5) Upper display (6) Lower display (7) KeypadThe main component of the EMCP II+ is the generator set control + (GSC+). 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+ 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
