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. 

Water Temperature 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.
