140KW Generator Operation Instructions

1. Check oil. It is not unusual for diesel engines to consume a little oil, especially during heavy load operation. While in the engine compartment, look around for leaks, loose wires, foreign materials; anything that might affect the performance.

2. Check radiator coolant. It is not necessary to remove the radiator cap. If coolant is visible in the plastic coolant recovery tank, you are ok. If a little is needed, put it in the recovery tank and it will work its way into the system. If a lot is needed, fill radiator and check for leaks. The coolant recovery tank is located inside the right-hand (when facing control panel) electrical door but can be viewed thru either electrical door.

3. Select either Single-Phase or Three-Phase operation. This must be done with the engine turned off and completely at rest. Do not switch with engine running. In Single-Phase you have 334 amps available on legs one (black) and two (red). In Three-Phase you have 375 amps available on legs one (black), two (red) and three (blue).

On generators equipped with the “480 VOLT” option a third position is available. In this position you have 150 amps available on legs one (black), two (red) and three (blue).

4. The circuit breaker is pre-set at 400 amps. On units with the “480 VOLT” option the breaker is equipped with a shunt trip, which is controlled by the CURRENT LIMITING feature in our computer when switched to 277/480 volt position.

SAFETY NOTE: At this point, you must close and lock both electrical doors.. These doors must never be opened or open able while the engine is running. This is the responsibility of the generator operator.

5. Open rear lid and its side flaps prior to starting. This lid is equipped with a safety switch that will cut off power to the computer when closed. It must be open to operate unit. The rear lid is mechanically linked to the covers over the engine and exhaust.

6. Apply power to computer by placing the Power switch to On. Start engine by placing Off/Run/Auto switch to Run. Normally, engine will start immediately. Note that there is no idle or slow speed mode. The engine will go to 1800 rpm (60hz). If engine fails to start, the system will turn off the starter, wait several seconds and automatically resume cranking.

7. Warm-up period. Allow engine temperature to rise to about 170 degrees before applying load.

8. While engine is warming up you may connect your cables to the output panel.

PLEASE FOLLOW THESE SAFETY INSTRUCTIONS

A. Make sure that the circuit breaker handle is in the Off (down) position.

B. Connect leads in the following sequence: Ground, Neutral, Leg 1, Leg 2, Leg 3 (IF USED)

C. Do not use circuit breaker to connect or disconnect a load unless it’s an emergency disconnect.

9. After engine is at operating temperature, turn circuit breaker handle to the On (up) position. Your cables are now live.

10. Adjust Voltage pot to desired output voltage. There is a fine adjust pot located at the display panel. If more range is desired, there is an additional adjustment located on the voltage regulator in the electrical compartment labeled Voltage Adjust.

11. Reading the output display. Engine and generator functions are continually displayed in two rows of information. In addition, total running time, time to next service, preset points, sending unit diagnostics and our phone number are available by placing the RTM switch in the up position.

CAUTION: By holding the RTM switch in the up position, information will continually scroll. When the information starts its third repeat, the Time To Service clock will be reset to 200 hours. You can see the information as many times as needed by releasing the momentary switch after each repeat.

The top row shows generator outputs. Voltage, Amperage and Cycles (Hz) are monitored for each leg. A number will be displayed under the phase sign that tells which leg is being monitored. This display continually cycle’s reading leg one, leg two, leg three and back to leg one. An individual leg can be continually monitored by placing the RTM switch in the Scroll Lock position.

The readings are leg to neutral with one exception. When the generator is running in single phase and the number three is displayed under the phase sign, you are reading the sum total of the voltage on leg one and leg two. No amperage will be displayed at this point.

The bottom row is engine outputs. Oil pressure, percentage of fuel remaining, water temperature and battery voltage are displayed.

If any of the displays are flashing a pre-fault condition is present. See Pre-Fault Alarm below.

TIME TO SERVICE notification. At start-up and in the RTM information the TIME TO SERVICE is shown along with the actual hours. For example, TIME TO SERVICE 84 HOURS. This timer starts at 200 hours of run time. When it reaches “0” a TIME TO SERVICE message is displayed with no hours showing. This will turn on the PRE-FAULT lamp but will not shut off the generator.

To reset this counter, hold the RTM switch in the up position long enough to scroll thru the information twice. At the start of the third repeat the counter will be reset to 200 hours.

12. Fault system. This generator is equipped with a fault shut down that will turn off the generator if any of the systems go outside the parameters that are set in the software. The preset points may be displayed by placing the RTM switch in the up position. If the generator shuts down because of a fault, the display panel will display the reason. Do not try to restart the generator until the message is observed and remembered. This will help in over-the-phone diagnosis.

Low Oil Pressure
Low Fuel Level (It shuts down after it reaches 1 Percent and stays there for 60 seconds).
High Coolant Temperature
Over Speed
Over Crank (The starter will shut down after _____ seconds and then automatically restart following a ____ rest.

13. Pre-fault alarm. This generator is also equipped with a pre-fault alarm that will alert the operator of a potential problem in the areas listed below. A pre-fault condition will not shut the generator down. If a pre-fault condition occurs the appropriate display will flash and the yellow pre-alarm lamp will turn on.

Low Oil Pressure
Low Fuel Level (warning starts at 15%)
High and Low Coolant Temperature
High and Low Battery Voltage
Oil Pressure Sending Unit Failure

14. Cooling the engine after use. It is highly recommended that the generator be allowed to run at least 10 minutes after the load has been turned off to allow the components to come down to a reasonable temperature.
