Wet stacking is a common problem with diesel engines which are operated for extended periods with light or no load applied. When a diesel engine operates without sufﬁ cient load (less than 40% of the rated output), it will not operate at its optimum temperature. This will allow unburned fuel to accumulate in the exhaust system, which can foul the fuel injectors, engine valves and exhaust system, including turbochargers, and reduce

Wet stacking does not usually cause any permanent

damage and can be alleviated if additional load is applied to relieve the condition. It can reduce the system performance and increase maintenance. Applying an increasing load over a period of time until the excess fuel is burned off and the system capacity is reached usually can repair the condition. This can take several

State Health Safety Codes and Public Resources Codes specify that in certain locations, spark arresters must be used on internal combustion engines that use hydrocarbon fuels. A spark arrester is a device designed to prevent accidental discharge of sparks or ﬂ ames from the engine exhaust. Spark arresters are qualiﬁ ed and rated by the United States Forest Service for this purpose. In order to comply with local laws regarding spark arresters, consult the engine distributor or the

DANGER

The engine fuel exhaust gases contain poisonous carbon monoxide. This gas is colorless and odorless, and can cause death if inhaled.

The engine of this equipment requires an adequate free ﬂ ow of cooling air. NEVER operate this equipment in any enclosed or narrow area where free ﬂ ow of the air is restricted. If the air ﬂ ow is restricted it will cause injury to people and property and serious damage to the equipment or engine.

INSTALLATION

CONNECTING THE GROUND

Consult with local Electrical and Safety Codes for proper connection based on condition of use.

EXAMPLE of how to ground the unit if the condition of use requires such a device:

The ground terminal on the generator should always be used to connect the generator to a suitable ground when required.

Either copper or aluminum wire can be used as the ground cable. Cable size is determined by the maximum amperage of the generator. Reference Conductor Grounding Table, Article 250 of the NEC handbook.

Connect one end of the ground cable terminal to the generator ground point (Figure 3). Connect the other end of the ground cable to a suitable earth ground (ground rod).

Page 17

INSTALLATION

OUTDOOR INSTALLATION

Install the generator in an area that is free of debris, bystanders, and overhead obstructions. Make sure the generator is on secure level ground so that it cannot slide or shift around. Also install the generator in a manner so that the exhaust will not be discharged in the direction of nearby homes.

The installation site must be relatively free from moisture and dust. All electrical equipment should be protected from excessive moisture. Failure to do will result in deterioration of the insulation and will result in short circuits and grounding.

Foreign materials such as dust, sand, lint and abrasive materials have a tendency to cause excessive wear to engine and alternator parts.

CAUTION

Pay close attention to ventilation when operating the generator inside tunnels and caves. The engine exhaust contains noxious elements. Engine exhaust must be routed to a ventilated area.

GENERATOR GROUNDING

NOTICE

The Occupational Safety and Health Administration (OSHA) and the National Electrical Code (NEC) recommend that if the generator is providing electrical power to a structure (home, ofﬁce shop, trailer or similar) it must be connected to a grounding electrode system, such a driven ground rod (Figure 3).

If applicable, to guard against electrical shock and possible damage to the equipment, it is important to provide a good EARTH ground, (Figure 3).

NOTICE

ALWAYS check with State, Province, District and Municipalities for electrical grounding requirements before using generator.

Article 250 (Grounding) of the NEC handbook provides guidelines for proper grounding and speciﬁes that the cable ground shall be connected to the grounding system of the building as close to the point of cable entry as practical.

INDOOR INSTALLATION

Exhaust gases from diesel engines are extremely poisonous. Whenever an engine is installed indoors the exhaust fumes must be vented to the outside. The engine should be installed at least two feet from any outside wall. Using an exhaust pipe which is too long or too small can cause excessive back pressure which will cause the engine to heat excessively and possibly burn the valves.

MOUNTING

The generator must be mounted on a solid foundation (such as concrete) and set ﬁrmly on the foundation to isolate vibration of the generator when it is running. The generator must be mounted at least 6 inches above the ﬂoor or grade level as referenced in the National Fire Protection Association (NFPA 110, Chapter 7, section 7.4) handbook.

DO NOT remove the metal skids on the bottom of the generator. They are to resist damage to the bottom of the generator and to maintain alignment.

1. Use one of the following wire types to connect the generator to earth ground.

a. Copper

b. Aluminum

NOTICE

Reference Conductor Grounding Table, Article 250 of the NEC handbook for proper conductor wire size. Wire size is determined by the maximum amperage of the generator.

2. When grounding of the generator (Figure 3) is required, connect one end the ground cable to the ground lug on the generator. Connect the other end of the ground cable to the ground rod (earth ground).

3. NEC Article 250 speciﬁes that the earth ground rod should be buried a minimum of 8 ft. into the ground.

 Ground Terminal

Engine Protection System

Engine protection fail safe features are provided in the event of low oil pressure, high coolant temperature and failure of the battery to charge. If any of the above conditions occur while operating the generator it will cause a complete unit shut down.

Battery Charge Alarm

This unit is equipped with a protective shutdown device that signals the emergency relay and automatically stops the engine when loss of charge from the engine alternator occurs. An indicator lamp will be displayed on the control panel.

Water Temperature Alarm

This unit is equipped with a temperature switch that signals the emergency relay and automatically stops the engine when the temperature of the engine coolant becomes abnormally high.

The coolant temperature switch will not function properly if the machine is operated with less than the proper amount of coolant.

Oil Pressure Warning Alarm

This unit is equipped with an oil pressure switch that detects low oil pressure. If the lubricating oil pressure of this unit should become abnormally low, the oil pressure switch signals the emergency relay to shutdown the engine. If this condition should occur, please refer to the engine troubleshooting table in this manual.

Idle Control Switch

The DA7000SSA3 generator is provided with an automatic idle (engine) control capability for noise suppression and fuel cost reduction. The automatic idle control feature automatically engages under a no-load condition when the switch is in the ON position.

With AC loads of more than 100W (such as lighting equipment, motor-powered tools, submersible water pumps, etc.), the engine runs at high speed. When a no load condition is produced, the engine automatically slows down.

Turn the idle control switch to the “ON” (up) position when AC loads drawing more than 150W are connected. Turn the idle control switch to the “OFF” (down) position when AC loads drawing less than 100W or when a magnetic switch is used.

Excitation System

The DA7000SSA3 generators use a brushless exciter to create rated output electricity. This system will use the mechanical energy generated by the 3600 RPM engine to spin the rotor (or armature) inside the generator (or alternator end).

Excitation current is sourced from the battery to the excitation winding in the stator. Current applied to this coil creates a magnetic ﬁeld. The rotating armature within the stator is then induced with AC current.

Engine

The DA7000SSA3 generator is powered by a water-cooled, 4-cycle KUBOTA diesel engine. This engine is designed to meet every performance requirement of the generator. Reference Table 2, engine speciﬁcations.

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