Axial Alignment Procedure adjustment

Tools: Dial indicator holding device, Magnetic base or clamp

Perform only when an objectionable vibration is present.
Fasten dial indicator holding device to skid base, engine block, or generator shell so the sensor rests on the generator shaft hub.
Bar the engine over clockwise through a couple of rotations and record readings in eight equally spaced points around the shaft diameter.
To correct out-of-tolerance T.I.R., remove the capscrews connecting drive discs and flywheel; mark drive discs and flywheel.
Rotate engine or generator so drive disc holes are repositioned 180 degrees from original location; retorque capscrews.
Re-check shaft alignment; if unchanged, rotate discs 30, 60, or 90 degrees from original location.
If T.I.R. still does not improve, inspect flywheel pilot and drive disc runouts.

Bus Voltage Calibration (C) adjustment

Tools: Calibrated voltmeter

Display the Bus Voltage Calibration submenu.
With all gensets OFF, attach a calibrated voltmeter to TB1-A (L1) and TB1-B (L2) of the bus PT module.
Start another genset, allow it to reach normal speed and voltage, and connect operating genset to the bus.
Calibrate the Bus Volts L1 reading so the display matches the calibrated meter.
Shut the generator set OFF.
Repeat steps 2 through 5 for Bus Volts L2 and L3.
Exit menu to save changes.

Frame 7 Angular Alignment Procedure adjustment

⚠ Disconnect negative battery cable(s) before beginning; accidental starting presents hazard of severe personal injury or death.

Tools: Dial indicator, Shims

Disconnect the negative (–) battery cable(s) before beginning.
Fasten a dial indicator to the generator shaft or cooling fan with the sensing point on the capscrew head or flat of the drive disc at bolt circle diameter.
Bar the engine over clockwise (viewed from engine flywheel); do not allow it to roll back on compression.
Record T.I.R. as the sum of the maximum positive and negative readings over one revolution.
To correct, remove or add equal shims under the four generator mounting feet.
Approximate shim change: multiply (step 1 to step 2 distance ratio) by one half the T.I.R.

Generator Mount Pre-Load Adjustment adjustment

⚠ Accidental starting of the generator set during this procedure presents the hazard of severe personal injury or death.

Tools: two 1 3/4 inch T x 2 inch W x 6 inch L steel spacers, adequate lifting device

Genset Voltage Display Calibration (A) adjustment

⚠ Contacting high voltage components can cause electrocution; calibration must be performed by technically qualified personnel only.

Tools: Calibrated RMS multimeter (Fluke 87 or 8060A)

Display the Voltage Calibration submenu.
With the genset OFF, attach a calibrated voltmeter to the AC output from L1 to L2.
Start the genset and allow it to reach normal operating speed.
Calibrate voltage reading for L1 so the display agrees with the calibrated voltmeter.
Shut the generator set OFF.
Repeat steps 2 through 5 for L2 and L3.
Exit menu to save changes.

Magnetic Pickup Adjustment adjustment

⚠ Jam nut over-torque will damage the magnetic pickup.

Tools: feeler gauge, torque wrench

Ensure a ring gear tooth is centered under the magnetic pickup hole. Rotate flywheel if necessary.
Screw the magnetic pickup in until it contacts the targeted gear tooth. Do not use excessive pressure.
Back the magnetic pickup out (counterclockwise) 1/2 to 3/4 turn.
If a feeler gauge can be inserted between the magnetic pickup and the flywheel ring gear tooth, back the magnetic pickup out 0.71 to 1.07 mm [0.028 to 0.042 in.] from the gear tooth.
Tighten the jam nut on the flywheel housing. While holding the magnetic pickup, torque the jam nut to 34-47 N-m [25-35 ft-lb].

Generator/PCC Control Isolation Procedure diagnostic

⚠ HIGH VOLTAGE. Touching uninsulated high voltage parts inside the control box can result in severe personal injury or death.

Tools: Jumper leads, 12 volt battery, Voltmeter

Throw line circuit breaker OFF and shut down the set.
Remove electronics box cover; remove connector 10 from regulator output module.
Prepare to measure output voltage across generator terminals while set is running.
Bring jumpers from a 12 volt battery to X (Field +, red wire 10-6) and XX (Field –, brown wire 10-3) pins of plug P10.
Check polarity again; polarity must be correct or test is inconclusive.
Start the set and connect the jumper from battery negative terminal to the XX lead.
If rated voltage or higher and phases balanced, generator circuitry is probably okay; otherwise troubleshoot.
If voltages unbalanced, troubleshoot main stator first; if uniformly low, troubleshoot exciter and field circuits first.

Megger and PI Test diagnostic

⚠ Hazardous voltage. After DC test voltage applied, reconnect Grounding Cluster to remove static charge after each test.

Tools: Megger

Perform the Generator Set Grounding Procedure.
Disconnect connector 10 from voltage regulator output stage and AC control leads 5,6,7,8.
If RTD option installed, ground all six RTD temperature leads (18 leads total).
Main Stator: remove and separate neutral leads from terminal 'N'.
Connect megger between one stator phase and ground, grounding other two phases; test.
Repeat stator test for the other two phases.
Main Rotor: disconnect rotor and voltage suppressor leads from F1+ and F2-.
Connect megger between one rotor lead and ground and conduct the test.
