DCA-220SSK — GENERAL INFORMATION (OPTIONS)

CAUTION :

The DCA-220SSKis powered by a 4 cycle, water cooled, turbocharged KOMATSU Model SA6D125E-2 diesel engine. This engine is designed to meet every performance requirement for the generator. Reference Table 1, page 16 for engine specifications.

In keeping with Multiquip's policy of constantly improving its products, the specifications quoted herein are subject to change without prior notice.

The basic controls and indicators for the DCA-220SSK generator are addressed on the following pages.

Electronic Governor System

The electronic governor system replaces the standard mechanical governor system. The frequency regulation improves from ±3.0% regulation with the mechanical governor to ±0.25% regulation with the electronic governor system.

JacketWater Heater

The jacket water heater is a 1500-watt heater designed to keep the coolant warm in the engine block for fast starts and load acceptance. The heater is thermostatically controlled and once an acceptable engine temperature is achieved it will cycle on and off, operating only about 1/3 of the time, which makes it more efficient than the direct block type heater. It is designed to keep the engine coolant between 100 and 120 degrees Fahrenheit.

Under normal conditions, 20 to 15 minutes is required to raise the engine temperature of a cold engine to 100 degrees Fahrenheit.

NOTE:

The jacket water heater can be serviced if not functioning properly.

ALWAYS unplug the jacket water heater before servicing.

Battery Charger

The battery charger will operate in a ‘BOOST’ mode until the battery’s current acceptance falls to 70% of the charger’s rating. The charger will then go into a ‘FLOAT’ mode, where it discharges a lower voltage until an AC failure, or the battery is discharged.
