Common problems

When the engine oil pressure is increased beyond the low oil pressure setpoint, the GSC will inform the governor that the engine speed should be increased from IDLE to RATED rpm. 2301A Control
The GSC+ detects an alarm fault
Fix: Fault alarm indicator (26) is accompanied by an alarm fault code that is shown on the upper display (29) when the alarm codes key (30) is pressed.
The GSC+ detects a shutdown fault
Fix: The engine will shut down if the engine is running. The engine will not be allowed to start.
The fault alarm indicator (3) flashes when the GSC detects an alarm fault. g00604607
Overcrank
Cause: Engine does not start within the setpoint for overcrank.
Low oil pressure indicator flashes, and the engine is shut down.
Cause: The engine oil pressure drops below the setpoints for low oil pressure shutdown that are programmed into the GSC. There are two low oil pressure setpoints. One setpoint is used when the engine is at idle speed. The other setpoint is used when the engine is at rated speed.
Low oil pressure
Cause: Engine oil pressure drops below the setpoints for low oil pressure shutdown that are programmed into the GSC+.
Fix: The tow oil pressure indicator FLASHES, and the engine is shut down. The engine is not allowed to start until the fault is corrected.
High water temperature indicator flashes, and the engine is shut down.
Cause: The engine coolant temperature rises above the setpoint for high water temperature shutdown that is programmed into the GSC.
High water temperature
Cause: Engine coolant temperature rises above the setpoint for high water temperature shutdown that is programmed into the GSC+.
Fix: The engine is shutdown and the engine is not allowed to start until the fault is corrected.
Generator parameters are not matched to the bus
Fix: If the generator and bus voltages, frequencies and phases are in sync, the lamps will light continuously. If not, the associated lamp will flash.
Fault shutdown 21
Fault alarm 22
Engine overspeed indicator flashes, and the engine is shut down.
Cause: The engine speed exceeds a certain threshold set in the GSC+.
Fix: Correct the condition by addressing any issues that caused the engine to overspeed.
Engine overspeed
Cause: Engine speed exceeds the setpoint for engine overspeed that is programmed into the GSC+.
Fix: The engine is shutdown and the engine is not allowed to start until the fault is corrected.
Engine overcrank indicator flashes, and the engine is shut down.
Cause: The engine has been cranked for an extended period without starting.
Fix: Correct the condition by ensuring proper start-up procedures are followed.

Procedures

VR3 Regulator Adjustment Procedure adjustment

⚠ The VR3 regulator is protected by a fuse(s) and a solid-state overcurrent protection. If a fuse becomes open, contact a Caterpillar dealer.

Remove the access panel of the generator.
Loosen the locknut on the voltage droop potentiometer (1).
Remove the protective screw from the voltage level potentiometer (2) and from the voltage gain potentiometer (3).
Turn the voltage droop potentiometer (1) counterclockwise to zero droop. Tighten the locknut.
Turn the voltage gain potentiometer (3) counterclockwise to zero, then to about 1/4 of full range of clockwise travel.
Perform required maintenance on the engine before you start the engine.
Start the engine and allow the engine to warm up.
Increase engine speed to full governed rated speed (high idle).
Set the no-load voltage with the voltage level potentiometer (2) or the voltage adjust rheostat.
Close the load circuit breaker and apply full load gradually. Adjust governor control to nameplate frequency or rated speed.
If the voltmeter reading increases above no-load voltage, turn the voltage gain potentiometer counterclockwise. If it decreases, turn it clockwise.
Remove the load. If necessary, adjust the voltage level potentiometer (2) to obtain desired voltage.
Apply the load. Repeat Steps 10 through 12 until the voltage at no load equals the voltage at full load.
Tighten the locknuts. Install the protective screws and the access panel of the generator.

Verify overload (OL) readings on reverse bias
Replace rectifier block if any reading is outside specifications

Varistor - Test diagnostic

Tools: Ohmmeter, Test Light

Using an ohmmeter, place the ohmmeter across the varistor. The resistance should be a minimum of 15000 ohms.
Disconnect either lead of the varistor (CR7).
Place the test light across the varistor.
Observe the results. The lamp should not light.
Reverse the test light.
Observe the results. The lamp should not light.
If the test light illuminates in either direction, there is a short in the varistor. Replace any faulty varistors with comparable operating characteristics.

Winding Resistance Measurement diagnostic

⚠ Temperature affects resistance; test at room temperature only

⚠ Winding damage if outside specifications

Tools: Digital Multimeter, Milliohmmeter (Wheatstone Bridge)

Disconnect winding from other components before measuring

Bearing (Ball) - Lubricating Process maintenance

Tools: Grease fitting, 8F-9866 Grease gun

Remove either the louver assembly or the rear plate from the rear of the generator housing.
Remove the top grease pipe plug and remove the lower grease pipe plug.
Install a grease fitting in the grease pipe.
Grease the shielded ball bearings with 2S-3230 Bearing Lubricant (53.28 mL (1.8 ounces) to 59.20 mL (2.0 ounces)).
Wipe off the excess grease. Remove the top grease fitting. Install the plug.
Operate the generator for one hour to allow the grease to expand and force excess grease from the cavity.
Stop the engine. Install the plug in the bottom grease pipe and wipe off the excess grease.
Install the louver assembly or install the rear plate.

Generator - Dry (Controlled Current Method) maintenance

Tools: 8T-0900 Clamp on ammeter (1200 amperes), External Power Source, Rheostat

Make an external power source.
Disconnect F1+ and F2- from the voltage regulator. Disconnect the generator load. Connect generator output leads T0, T1, T2, and T3. Install the clamp-on ammeter on output lead T1.

For power, sensing, and control circuitry, remove the transformer's fuses.
Attach a DO NOT OPERATE or similar warning tag to the generator excitation controls.
Remove the cover of the generator's terminal box.
Use an audio/visual proximity tester insulated for the proper voltage rating to verify the generator is de-energized.
Add ground straps to the conductors or terminals. During the entire work period, these ground straps must remain connected.

Recommended Periodic Insulation Test Procedure maintenance

⚠ Personal injury or death can result from electrocution. The megohmmeter applies a high voltage; discharge the leads before touching.

Use the 30/60 Time Resistance Method: apply voltage and observe readings at 30 seconds and 60 seconds.
Record the 60 second reading corrected for temperature. Record temperature and humidity. Remove voltage.
Evaluate the readings by comparing the 60 second resistance reading with previous readings taken under similar conditions.
Switch the insulation tester to OFF to discharge the leads, then disconnect the insulation tester's leads.
