ENGINE OPERATING PANEL

The definitions below describe the controls and functions of the DCA-45SSIU4 Engine Operating Panel (Figure 5).

1.Warning Lamp — This lamp will illuminate whe a critical engine fault has occured.

2.Preheat Lamp — As the engine cranks, this lamp will illuminate to indicate automatic preheating of the engine glow plugs. When the lamp turns off, this indicates that the preheat cycle is complte and the engine will start automatically.

3.Panel Light — Normally used in dark areas or at night time.When activated, panel lights will illuminate.When the generator is not in use be sure to turn the panel light switch to the OFF position.

4.Panel Light Switch — When activated will turn on control panel light.

5.Oil Pressure Gauge — During normal operation this gauge should read between 42 ~71 psi. (290~490 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.

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

7.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.

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

9.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.

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

11.Auto START/STOP Engine Controller (ECU) — This controller has a vertical row of status LED's (inset), that when lit, indicate that an engine

malfunction (fault) has been detected. When a fault has been detected the engine controller will evaluate the fault and all major faults will shutdown the generator. During cranking cycle, the ECU will attempt to crank the engine for 10 seconds before disengaging.

If the engine does not engage (start) by the third attempt, the engine will be shutdown by the engine controller’s Over Crank Protection mode. If the engine engages at a speed (RPM's) that is not safe, the controller will shutdown the engine by initializing the Over Speed Protection mode.

Also the engine controller will shut down the engine in the event of low oil pressure, high coolant temperature, low coolant level, and loss of magnetic pickup. These conditions can be observed by monitoring the LED status indicators on the front of the controller module.

A.MPEC Control Switch — This switch controls the running of the unit. If this switch is set to the OFF/ RESET position, the unit will not run. When this switch is set to the manual position, the generator will start immediately.

If the generator is to be connected to a building’s AC power source via an automatic transfer switch (isolation), place the switch in the AUTO position. In this position, should an outage occur, the automatic transfer switch (ATS) will start the generator automatically via the generator’s auto-start contacts connected to the ATS’s start contacts. Please refer to your ATS installation manual for further instructions for the correct installation of the auto-start contacts of the generator to the ATS.

B.Low Oil Pressure — Indicates the engine pressure has fallen below 15 psi (103 kPa). The oil pressure is detected using variable resistive values from the oil pressure sending unit. This is considered a major fault.

C.High Coolant Temperature — Indicates the engine temperature has exceeded 230°F (110°C).The engine temperature is detected using variable resistive values from the temperature sending unit. This is considered a major fault.

D.Overcrank Shutdown — Indicates the unit has attempted to start a pre- programmed number of times, and has failed to start. The number of cycles and duration are programmable. It is pre-set at 3 cycles with a 10 second duration. This is considered a major fault.

E.Overspeed Shutdown — Indicates the engine is running at an unsafe speed. This is considered a major fault.

F.Engine Running — Indicates that engine is running at a safe operating speed.
