SPRING 3342679 - Caterpillar

Introduction
Standard floor-standing switchgear units incorporate a comprehensive system of components for generator set control, monitoring and protection. This system's approach to genset management results in unsurpassed reliability, capability and performance for many applications.Switchgear includes:* Caterpillar EMCP II Controls* Fix-mounted Circuit Breaker* Governor Controls* NEMA 1 Floorstanding EnclosureAll these "standard" features-and the many functions they represent-are conveniently housed in a NEMA 1 cabinet for indoor use. The cabinet is fabricated with steel barriers between power and control sections.Location of Components

GSC Display Area With Service Mode Descriptions Of Keypad
(1) Dedicated shutdown indicators. (2) Fault shutdown indicator. (3) Fault alarm indicator. (4) Upper display. (5) Lower display. (6) Keypad.Caterpillar's Electronic Modular Control Panel II (EMCP II) is at the core of switchgear operations. In turn, the EMCP II has as its main component 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:* Controls normal 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.Fault Indicators
