PRODUCT INFORMATION BULLETIN

for Control Board # 0830890SRV

SUBJECT: C Option Engine Control PCB Adjustment Procedure

MODELS AFFECTED: All generator sets utilizing a C Option control panel.

PROBLEM: Overspeed and starter disengage calibration.

CORRECTIVE ACTION: This adjustment must be done to ensure proper operation.The following

adjustment is for setting the engine OVERSPEED shutdown function.This

adjustment also serves as the starter disengage speed setpoint. If this adjust-

ment is not properly made it could cause damage to the engine or alternator

in an overspeed condition, or to the starter and ring gear if the starter does

not properly disengage.

1. Before starting the generator, turn COARSE adjustment pot full

CLOCKWISE, FINE pot COUNTER-CLOCKWISE.

2. Start engine, make sure engine is up to rated speed.

3. Turn COARSE pot slowly until red LED on PCB board turns on.

4. Turn FINE pot slowly until red LED goes out.

5. Turn FINE pot back slowly until red LED turns back on.

6. Verify proper overspeed shutdown by manually increasing engine speed

until engine shuts down.Verify that engine shutdown occurs at 72 Hz. If

not, slightly adjust FINE pot to achieve proper shutdown speed.This will

also ensure that the starter disengages at approximately 500 rpm.

MORE DETAILED INSTRUCTIONS on the back page.

1. On the circuit board, locate potentiometers R26 and R27. See Figure 1. Also, locate the

red LED.

2. Turn the COARSE (R26) pot all the way clockwise (CW).

3. Turn the FINE (R27) pot all the way counterclockwise (CCW).

4. Start the generator engine manually, using the Start/Stop switch. Let the engine stabilize

and warm up at no-load. If necessary, adjust the engine

governor to obtain normal rated operating speed.

5. With the unit running at no-load and at its normal rated speed, slowly turn the COARSE

(R26) pot counterclockwise (COW) until the red LED just turns on.

6. Slowly turn the FINE (R27) pot clockwise (CW) until the red LED just goes out.

7. Slowly, turn the FINE (R27) pot counterclockwise (CCW) until the red LED just turns on.

With the board properly calibrated, overspeed shutdown will occur at approximately 10

Hertz above the unit's normal operating frequency. For example, if the engine no-load

speed is 62 Hertz, overspeed shut-down will occur at

approximately 72 Hertz.

MORE DETAILED INSTRUCTIONS from Generac Diagnostic Repair Manual # 79247:

CAUTION: Steps 2 and 3 MUST be completed BEFORE THE ENGINE IS STARTED. If the engine is

started before the steps are completed, an over-speed shutdown may occur at normal rated operating

speed.
