DCA-220SSVU — ENGINE OPERATING PANEL

The definitions below describe the controls and functions of the DCA-220SSVU Engine Operating Panel (Figure 7).

1.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.

2.Panel Light Switch – When activated will turn on control panel light.

3.Oil Pressure Gauge – During normal operation this gauge be should read between 44 to 73 psi. (303~503 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.

4.WaterTemperature Gauge – During normal operation this gauge be should read between 165° and 203°F.

5.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.

6.Fuel Gauge - Indicates amount of diesel fuel available.

7.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.

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

9.Pre-Heat Button – Press and hold this button for 50 seconds to warm (cold weather) the engine glow plugs.

10.Coolant Alarm Lamp – This lamp will illuminate when the coolant level falls below a safe operating level.

11.Auto On/Off Engine Controller (MPEC) –

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 MPEC 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 a transfer switch (isolation), place the switch in the AUTO position. In this position the generator will monitor the AC line output from the building's power source.

B.Low Oil Pressure – Indicates the engine pressure has fallen below 15 psi. 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 239°F. 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.
