The defi nitions below describe the controls and functions of the DCA400SSI Engine Operating Panel (Figure 5).

1.Tachometer — Indicates engine speed in RPM’s for 60 Hz operation. This meter should indicate 1800 RPM’s when the rated load is applied. In addition a built in hour meter will record the number of operational hours that the generator has been in use.

2.Oil Pressure Gauge — During normal operation this gauge be should read between 28 to 85 psi. (193~586 kPa).When starting the generator the oil pressure may read a little higher, but after the engine warms up the oil pressure should return to the correct pressure range.

3.WaterTemperature Gauge — During normal operation this gauge be should read between 167° and 203°F (75°~95°C).

4.Charging Ammeter Gauge — Indicates the current being supplied by the engine’s alternator which provides current for generator’s control circuits and battery charging system.

5.Fuel Gauge — Indicates amount of diesel fuel available.

6.Engine Warning Lamps — There are three engine warning lamps, they are defi ned as follows:

a.Overheat Lamp — This lamp goes ON when the cooling water temperature rises abnormally. If the lamp goes ON during normal operation of the generator, the emergency shutdown device will stop the engine automatically.

b.Low Oil Pressure Lamp — During normal operation of the generator this lamp should remain OFF. When the Auto-OFF/Reset-Manual switch is set

to the MANUAL position to start the engine, the lamp will be lit. When the oil pressure rises after start-up the lamp will go OFF. If this lamp is ever lit (ON) during normal operation of the generator, the emergency shutdown device will stop the engine automatically.

c.Low Fuel Level Lamp — When this lamp is ON, it is time to stop the engine and add fuel. Remember to let the engine cool before adding fuel.

d.Air Filter Alarm — When the air fi lter

element is clogged, this lamp goes ON indicating the element should be immediately cleaned or replaced.

e.Coolant Level Alarm — This lamp

goes ON when the coolant level is low. If this lamp goes ON while the engine is in operation, the emergency shutdown device will automatically stop the engine.

7.Engine Speed Switch — This switch controls the speed of the engine (low/high).

8.Pre-Heat Lamp — When ECU is placed in AUX position, pre-heat lamp will be ON. When pre-heat cycle is completed, lamp will turn OFF.

9.Emergency Stop Button — Push this button inward to stop the engine in the event of an emergency. DO NOT use this button as a means of stopping the engine.

10.Battery Switch — This switch should be set to the ON position during normal operation.When the engine has been stop, place this switch in the OFF position. DO NOT turn this switch during normal operation, it could cause damage to the electrical equipment.
