Multiquip DCA-220SSJ operation manual Engine Speed Switch High

When the MPEC Control switch is

NOTE placed in the manual position, preheating of the glow plugs will begin automatically and the preheat lamp will stay lit until the

glow plugs are warmed. When the preheat lamp goes off this signals the completion of the preheating cycle and the starting of the engine.

3.If any abnormalities exists, the Warning and Emergency Stop lamps on the Engine Operating Panel will be lit.

4.Place the MPEC Control Switch (Figure 42) in the OFF/RESET position.

5.Place the Diagnostic ON/OFF switch in the ON position. Verify that an Active Fault Code message is being displayed (Diagnostic Display Panel). The fault code message will continued to be displayed until the fault has been corrected. Figure 43 shown below is a typical example of an active fault code message (Low Radiator Coolant).

8.To restart the engine due to error codes, place the MPEC Control Switch in the MANUAL position (Figure 42)

9.If the engine is running smoothly, place the engine speed switch (Figure 44) in the “HIGH” (up) position.

11.Observe that the Warning and Emergency Stop lamps on the Engine Operating Panel are OFF.

12.The generator's frequency meter (Figure 46) should be displaying the 60 cycle output frequency in HERTZ.

6.In a situation where several engine problems occur simultaneously, the word “MORE” appears above the arrow buttons indicating that there are more fault codes that need to be viewed. Use the arrow buttons to scroll to the next active fault code.

If desired, the type of fault code, cause of error and the countermeasures of the error can be referenced in a separate engine operator’s manual.

7.Before the engine can be started, the engine fault must be corrected. Also observe that there are no active fault codes displayed on the diagnostic panel. If no fault codes are displayed, place the diagnostic switch in the OFF position.

13.The generator's AC-voltmeter (Figure 47) will display the generator’s output in VOLTS. If the voltage is not within the specified tolerance, use the voltage adjustment control knob (Figure 48) to increase or decrease the desired voltage.
