Generator Set Control + (GSC+)
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) Keypad.The main component of the EMCP II+ system is the generator set control + (GSC+). The GSC+ is designed to operate when powered by only 24 DCV or 32 DCV battery systems. The GSC+ monitors and controls many of the generator set (genset) functions. The functions and features of the GSC+ are:* Provides generator AC output information including power metering.* Controls starting and stopping of the engine.* Shows engine conditions and generator output information on two displays. The displays also show fault codes and GSC+ programming information.* Monitors the system for faults. If a fault occurs, the GSC+ performs a controlled fault shutdown or provides a fault alarm annunciation. The GSC+ uses indicators and displays to describe the fault to the operator or service technician.* Contains programmable features for certain applications or customer requirements. In order to ensure proper operation on MUI engines, the GSC+ setpoint P023 must be set to 0. Failure to do this 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 Engine/Generator Programming OP5-0 within the topic Service Mode.GSC+ Part
