Exhaust System. Check for exhaust leaks and blockages. Check the muffler condition.
•Inspect the exhaust system components for cracks, leaks, and corrosion. Check for tight exhaust system connections.
•Check for corroded or broken metal parts and replace them as needed.
•Check that the exhaust outlet is unobstructed.
Oil Level. Check the oil level before starting the generator set and at the intervals given in Section 4, Scheduled Maintenance. Maintain the oil level at or near, not over, the full mark on the dipstick.
Operating Area. Check for obstructions that could block the flow of cooling air. Keep the air intake area clean. Do not leave rags, tools, or debris on or near the generator set.
2.3 Exercising the Generator Set
Operate the generator set without load once each week or every 2 weeks for 20 minutes. See Section 2.5, Exercise. For instructions to set the exerciser, see Section 3.6.
2.4 Generator Set Operation
2.4.1Local Starting and Stopping
Start: Press the RUN button to immediately start the generator set.
Stop: Press the OFF button. The engine stops.
Run the generator set with no load for at least
2 minutes to ensure adequate engine cooldown.
2.4.2Remote Starting and Stopping
The generator set must be in automatic mode for remote operation. Press the AUTO button on the VSC controller.
A remote switch connected to terminals 3 and 4 can be used to start and stop the generator set. Close the switch to start and run the generator set. Open the switch to stop the generator set.
Run the generator set with no load for at least
2 minutes to ensure adequate engine cooldown.
2.4.3Engine Start Crank Cycle
The controller attempts to start the generator set three times (three crank cycles, 15 seconds crank and
15 seconds off). If the generator set does not start in three attempts, the system shuts down on an overcrank fault. See Section 2.6.
Cranking 1, 2, and 3 are displayed during the crank cycle. Pressing the OFF button during the crank cycle
stops the cranking. No other buttons are acknowledged during the crank cycle.
2.4.4Engine Cooldown
The engine cooldown time delay allows the engine to run after the loads have been removed.
The engine cooldown time delay is set to 5 minutes. The engine stops before the cooldown time delay expires if the temperature drops below the
2.4.5Automatic Operation
The 6VSG monitors the voltage of a storage battery bank connected to (+) and
•If the storage battery voltage falls below the minimum voltage for more than 3 minutes, or if a remote start command is received, the generator set starts. A remote start command can be activated by closing the remote start contacts across 3 and 4 or by a start exercise command.
•When the generator set load falls below the minimum % load for more than 3 minutes, or a remote stop command is received, the generator set stops. A remote stop command can be caused by opening the remote start contacts across 3 and 4 or by the exercise time ending.
The minimum voltage, minimum load, and time delays are adjustable using a personal computer and Kohler® SiteTech™ software. Contact your Kohler distributor.
