The Caterpillar
®
EMCP 3.3 includes fully featured power metering, protective relaying and
engine and generator control and monitoring. Engine and generator controls, diagnostics,
and operating information are accessible via the control panel keypads; diagnostics from the

overcurrent, and reverse power.
• Digital, 32-bit microprocessor-based system eliminates the need for multiple switches,
meters, transducers, relays, and sending units, which translates to less wiring and
fewer opportunities for mechanical failures.
• Expanded remote customer communications are supported by MODBUS RTU (1/2
