EMCP 4.1The EMCP 4.1 provides basic engine controls – stop/run/auto push button controls, cycle crank, and cool down timer. The 3.8 inch graphical display supports multiple languages, including character languages such as Chinese, Arabic, Russian, and Japanese. The EMCP 4.1 provides monitoring of generator electrical output, including AC voltage, current, and frequency, and mechanical information such as oil pressure, oil temperature, coolant temperature, engine speed, and battery voltage. It also provides a number of protective functions, such as warnings and shutdowns for over/under voltage, over/under frequency, low oil pressure, high coolant temperature, low coolant level, failure to start, and overspeed.
EMCP 4.2The EMCP 4.2 builds on the features of the EMCP 4.1 controller, offering expanded generator set protection and monitoring, such as generator kW, kVA, and kW-hr.
Flexibility is also increased with the addition of a modbus RTU communication port, remote annunciator modules, and expansion I/O modules to allow the EMCP 4 system to be configured to meet site specific design requirements.
With the additional monitoring and expansion modules available, the EMCP 4.2 is designed to provide control and protection for critical installations, such as NFPA-110 Level 1 applications.
EMCP 4
CAT EMCP 4
21
EMCP 4.3The EMCP 4.3 further expands the EMCP 4 product line with the addition of 5.5 inch graphical display and additional context specific navigation keys.
With the addition of a modbus TCP port, the EMCP 4.3 controller can be easily integrated into complex systems requiring complete generator set monitoring.
EMCP 4.4The EMCP 4.4 builds on the EMCP 4.3 functionality with the addition of fully automatic multi generator set paralleling. The EMCP 4.4 provides all of the functions required to automatically parallel generator sets, including dead bus arbitration, automatic or manual modes of operation, and load sharing (real and reactive). The EMCP 4.4 can also be configured to automatically cycle generator sets on line and off line based on the site load.

COMPARISON OF REDUCED VOLTAGE STARTING METHODS
*Resistor starting adds considerable kW load to generator set. Total power required includes the motor kW and the kW which is lost as heat in the resistor. The series resistors account for a higher than normal starting power factor.

ENGINE ROOM VENTILATION
Engine room ventilation can be estimated by the following formulas, assuming 100°F (38°C) ambient air temperature:
V (cfm) = H + Engine Combustion Air 0.070 x 0.24 x T
V (m3/min) = H + Engine Combustion Air 1.099 x 0.017 x T
V = Ventilation air (cfm) (m3/min).H = Heat radiation (Btu/min) (kW). T = Permissible temperature rise in engine room (°F) (°C).Density of air at 100°F = 0.070 lb/cu ft (1.099 kg/m3).Specific heat of air = 0.24 Btu/°F (0.017 kW/°C).

PRODUCT SUPPORT
PRODUCT SUPPORT DEFINITIONS
Extended Service Coverage (ESC)
Depending on the model and application, Silver, Gold, Platinum and Platinum Plus coverage levels are available from Caterpillar with terms to meet most applications, whether prime or standby.
Platinum and Platinum Plus provide additional allowances for overtime emergency freight, rental, crane and rigging support. Please see the registration contract for details.
Equipment Coverage Option New Product New ESC Existing Product Advantage ESC Overhauls OPC*
Electric Power ESC reimburses covered parts at customer list price, labor at selling rates and travel and mileage charges (less any deductibles) for covered repairs.
Available worldwide for all Cat Electric Power Products, ESC provides usual and customary parts and labor costs for covered system failures due to defects in materials and workmanship on components over the duration of the covered period.
*Overhaul Protection Coverage

• A Customer Support Agreement (CSA) is an arrangement between the end user and the Cat dealer that helps lower the cost per unit of production.
• Agreements are tailored to fit your business needs and can range from simple Preventive Maintenance Kits to sophisticated Total Cost Performance Guarantees.
• Qualified Factory Trained dealer technicians assist you by maintaining your Cat Electric Power Products and driving down operating costs. Perhaps the most important feature of any CSA is flexibility.
• A Preventive Maintenance (PM) agreement covers specified maintenance at a fixed cost. You maintain reliability and efficiency because the maintenance is performed by highly skilled technicians at guaranteed costs, giving you the ability to budget more accurately.
• A Total Maintenance and Repair (TM&R) agreement covers all of the maintenance and repair costs. Instead of paying for maintenance or repairs as they are needed, you pay one flat rate to cover a broad range of parts and services.
Check with your local Cat dealer for available options with each agreement.
