Start the generator set with master switch in RUN.
Use controller or remote voltage adjusting potentiometer to fine adjust voltage.
Apply resistive load (1.0 power factor) until reaching rated current.
Adjust reactive droop compensator rheostat to achieve a 4% droop in voltage.
Remove the resistive load and stop the generator set.
Return voltage sensing lead from V9 to V7 at the AC fuse terminal block.
Replace the controller cover and repeat for generator set no. 2.

Underfrequency Adjustment (Over/Underfrequency Relay, Decision-Maker 3+) adjustment

Turn underfrequency adjustment potentiometer fully clockwise (CW).
Place master switch in RUN to start the generator set.
Adjust governor per engine operation manual, engine service manual, or governor section of this manual.
Slowly turn underfrequency potentiometer counterclockwise (CCW) until LED starts flashing; after about 10 seconds the set shuts down on auxiliary fault.
Place master switch to OFF/RESET to reset the controller.
Place master switch to RUN to start the generator set.

Place master switch to OFF/RESET to stop the generator set.

Valve clearance - Check and adjustment adjustment

Tools: Feeler gauge Y20010128, Torque wrench 60-320 Nm F30047446, Ring socket, 24 mm F30039526

Remove cylinder head cover
Install barring tool
Rotate crankshaft until marking OT-A1 and pointer are aligned
Check TDC position of piston in cylinder A1
Check valve clearance with cold engine: inlet 0.2 mm, exhaust 0.5 mm
Check all valve clearances at two crankshaft positions
Use feeler gauge to determine distance between valve bridge and rocker arm
If deviation exceeds 0.1 mm, adjust valve clearance
Release locknut and set adjusting screw with Allen key
Tighten locknut to 90 +9 Nm holding adjusting screw firm

2-Wire Low Water Level Sender Test diagnostic

⚠ Hot engine and exhaust system can cause severe injury or death. Do not work on the generator set until it cools.

⚠ Hazardous voltage. Moving parts. Will cause severe injury or death. Operate the generator set only when all guards and electrical enclosures are in place.

Tools: DC voltmeter

Measure DC voltage between lead 31A (+) and ground (- ) with sender submerged in coolant; voltmeter indicates approximately 12.5 VDC.
Measure DC voltage between lead 31A (+) and ground (- ) with sender removed from coolant for at least 5-15 seconds; voltmeter indicates a drop to approximately 7 VDC.

3-Wire Low Water Level Sender Test diagnostic

⚠ Hot engine and exhaust system can cause severe injury or death. Do not work on the generator set until it cools.

⚠ Hazardous voltage. Moving parts. Will cause severe injury or death.

Tools: Ohmmeter

Measure resistance between lead 31 and ground with sender submerged in coolant; ohmmeter indicates a high resistance reading.
Measure resistance between lead 31 and ground with sender removed from coolant for at least 5-15 seconds; ohmmeter indicates a low resistance reading.

Battery Equalizer Troubleshooting diagnostic

⚠ To prevent reverse polarity damage to the battery equalizer, remove the ground (GND) connection first and attach the ground connection last when disconnecting the battery equalizer.

Tools: 12-volt test light with alligator clips, Voltmeter with 0.01 volt resolution, Battery load tester

Remove the ground (GND) connections from the battery equalizer; do not allow contact with other connections.
Verify a differential of 12 volts between the +12 volt and +24 volt terminals using a 12-volt test light; the light will illuminate on a functional unit. Remove the test light.
Connect the test light between the +12 volt and GND terminals; the light will illuminate on a functional unit.
With the test light connected, measure and record the voltage between the +12 volt and +24 volt terminals.
With the test light connected, measure and record the voltage between the +12 volt and GND terminals.
Remove the test light.
Compare the values from steps 4 and 5; the difference should be - 0.5 and +0.13 volts on a functional unit.

Tools: Rigid endoscope Y20097353

Remove cylinder-head cover
Remove injector
Turn crankshaft until crankpin of cylinder to be tested has reached BDC
Insert endoscope into cylinder liner through injector seat
Compile endoscopy report using the table
Depending on findings: no action, further examination, or contact Service (liner replacement)
Install injector

Oil Pressure Sender Testing diagnostic

Tools: Ohmmeter, Mechanical oil pressure gauge

Disconnect the oil pressure sender lead 7C.
Check the sender resistance with an ohmmeter.
Compare resistance values when the generator set is shut down and when running at operating temperature to Section 1, Specifications.
Use a mechanical oil pressure gauge to further verify correct readings.

Overcrank Test (Typical) diagnostic

On gas-fueled sets, disconnect the coil wire at the distributor cap and ground it or disconnect the ignition system.
On diesel-fueled sets, unplug the fuel injector harness from ECM or disconnect wire no. 70 from the injector pump solenoid.
Place unit in RUN mode; observe 15-second on-off cranking cycles and maximum 75-second elapsed time to overcrank shutdown.
Observe controller fault lamp and display for an overcrank shutdown.
Place unit in OFF/RESET mode.
Reconnect the ignition coil wire/ignition system, or reconnect the fuel injector harness/wire no. 70.
