Common problems

UNDERVOLTAGE 13
Fix: Reduce the number of connected appliances, especially when air conditioners and battery chargers are running.
UNDERFREQUENCY—Engine governor unable to maintain rated frequency CODE NO. 15
Fix: 1. Reduce the number of appliances running at the same time, especially those with high motor starting loads such as air conditioners. 2. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8).
The genset shuts down
Fix: See Troubleshooting (Page 7-1).
The genset fails to start
Cause: Cranking will discontinue in 20 to 60 seconds, depending on how cold the engine is, and the amber status lamp will blink Shutdown Code No. 4 (Page 7-5). See Troubleshooting (Page 7-1) if the genset does not start after two or three tries.
STARTER ENGAGES-DISENGAGES
Cause: (Battery voltage dips below 6 volts while cranking—low battery charge, poor connections, long cables)
Fix: 1. Clean and tighten the positive (+) and negative (- ) battery cable connections at the battery and gen-set (Page 17). 2. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations. 3. Increase battery cable size or run parallel cables.
SERVICE CHECK 3
Fix: Check the second-level shutdown code by pressing STOP once. The second-level shutdown code will have two-digits. The shutdowns are listed below in numerical order.
RUN-DOWN STARTING BATTERY
Cause: (Marginal battery, connections, or charging system or, parasitic loads)
Fix: 1. Clean and tighten the positive (+) and negative (- ) battery cable connections at the battery and gen-set (Page 17). 2. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations.
PROCESSOR FAILURE—Microprocessor ROM error during self-test CODE NO. 42
Fix: See an authorized Onan dealer.
PROCESSOR FAILURE—Microprocessor RAM error during self-test CODE NO. 43
Fix: See an authorized Onan dealer.
PROCESSOR FAILURE—Controller unable to sense field voltage CODE NO. 48
Fix: See an authorized Onan dealer.
OVERVOLTAGE 12
Fix: See an authorized Onan dealer.
OVERFREQUENCY 14
Fix: 1. If the line circuit breaker or any other circuit breaker has tripped, start the genset before resetting the breaker. (Frequency can overshoot when a circuit breaker trips under load.) If the genset continues to run, turn off or disconnect all loads, reset the breaker and bring the loads on one at a time without overloading the genset. 2. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 3. Prime the fuel system to remove air in the fuel lines (Page 8).
OVERCRANK 4
Fix: 1. Check the fuel tank and fill as necessary. (Note: The arrangement of pickup tubes in the fuel supply tank probably is such that the genset will run out of fuel before the propulsion engines.) 2. Open any closed fuel valves. 3. Remove any blockage in the combustion air inlet (front grille) or exhaust system. 4. Tighten loose fuel line fittings so that air cannot be drawn in by genset lift pump suction. 5. Drain and/or replace the fuel filter (Page 16) and prime the fuel system (Page 8). 6. Drain and/or replace fuel supply system filters and prime the fuel system (Page 8).
OVER-PRIME—Prime mode exceed 5 minutes CODE NO. 17
Fix: Check for and remove any object that may be holding either control switch (remote or local) in the prime position.
NO LIGHTS, NO RESPONSE
Cause: (Poor connections, faulty wiring or dead battery)
Fix: 1. Try the genset Control Switch if the remote Control Switch does not work, and vice versa. 2. Clean and tighten the positive (+) and negative (- ) battery cable connections at the battery and gen-set (Page 17). 3. Recharge or replace the battery. Refer to the battery manufacturer’s recommendations.

⚠ Keep your hands away from the engine belt and pulleys.

⚠ The actuator could overheat if the battery is left on more than 10 minutes.

⚠ Be prepared to clamp off supply and return fuel lines to stop the engine.

Tools: strobe or injector clamp-on tachometer, 12 volt battery, battery switch

Adjust the speed control lever stop.
Measure engine speed with a strobe or injector clamp-on type tachometer.
Remove the front and top access doors and loosen the front/left side panel assembly for access to the speed adjusting screw.
Disconnect the actuator leads and connect a 12 volt battery to the actuator terminals using a battery switch.
Switch the battery on, start the genset, measure engine speed (rpm) and stop the engine by switching off the battery.
Loosen the lock nuts on the two bottom screws and back out the clamping screw if speed is not between 3300 and 3400 rpm.
To increase speed turn the speed adjusting screw in 1 turn clockwise; to decrease turn it out 1 turn counterclockwise.
Repeat until high-idle speed is between 3300 and 3400 rpm and set the lock nut.
Run the clamping screw in by hand until snug, back it out 1-1/2 turns and set the lock nut.

Adjusting Speed Control Lever Stop adjustment

⚠ Accidental or remote starting can cause severe personal injury; disconnect the negative battery cable.

Remove the front and top access doors and loosen the front/left side panel assembly so it can swing left.
Loosen the stop screw locknut and back the screw out a few turns.
Turn the stop screw in until it just makes contact and set the locknut.

Adjusting V-Belt Tension adjustment

⚠ Accidental or remote starting can cause severe personal injury or death.

Disconnect the negative cable at the battery.
Remove the belt guard or enclosure top panel and access doors.
Loosen the alternator pivot bolt first, then the adjusting bracket bolt on top.
Pivot the alternator out to tighten belt tension.
Check tension by applying 20 pounds (10 kg) to the middle of the pulley span.
Tighten alternator bolts when deflection is 3/8 inch (10 mm), secure guard and reconnect cables, negative last.

Adjusting Valve Lash adjustment

⚠ Do not use the fuel injection timing marks when adjusting valve lash.

Rotate the engine clockwise (looking from the front) until the intake valve push rod just stops moving down (valve closed).
Turn the engine one half turn more.
Adjust lash for both intake and exhaust valves of that cylinder.
Repeat this procedure for the other cylinder.

Adjusting Voltage Using Control Switch adjustment

Tools: separate voltmeter

Start the genset and let voltage and frequency stabilize for 5 to 10 seconds with all loads disconnected.
Rapidly press START 6 times during the first minute after startup to enter voltage adjust mode.
To adjust voltage up, press and quickly release START (about 0.6 volts per press).
To adjust voltage down, press and hold START for about 2 seconds (about 0.6 volts each press).
Wait about 20 seconds for the amber lamp to stop blinking, then press STOP to save the adjustment.
Restart the genset and check voltage.

Adjusting Voltage Using Digital Display adjustment

Start generator set and let voltage and frequency stabilize 5 to 10 seconds; disconnect all loads.
Rapidly press START 6 times during the first minute after startup to enter voltage adjust mode.
Press and quickly release START to increase voltage approximately 0.6 volts per press.
Press and hold START about 1 second to adjust voltage down.
Wait about 20 seconds for status to change from Volt Adj to Running, then press STOP to save.
Restart the generator set and check voltage; recalibrate AC voltage on the digital display.

Adjusting Voltage Using Optional Digital Display adjustment

Tools: Separate voltmeter

Start the genset and let voltage and frequency stabilize for 5 to 10 seconds; make sure all loads have been disconnected.
Rapidly press START 6 times during the first minute after startup to put the genset controller into voltage adjust mode.
To adjust voltage up, press and quickly release START; voltage increases approximately 0.6 volts each press and release.
To adjust voltage down, press and hold START for about 1 second; voltage decreases approximately 0.6 volts each press and release.
Wait about 20 seconds for the Display to indicate a Status change from Volt Adj to Running, then press STOP to stop the genset and save the adjustment.
Restart the genset and check voltage.
Recalibrate AC Voltage on the Digital Display as instructed in the Operator's Manual.

Changing Frequency adjustment

The genset control box has jumper leads marked HZ SEL and 60 HZ.
Connect for 60 HZ; disconnect for 50 HZ.
Apply the appropriate reconfiguration label over the 'As Manufactured' block on the nameplate.

Changing Generator Set Frequency adjustment

⚠ When changing frequency, make sure the line circuit breakers are suitable for the new output.

Remove the control box cover.
Connect J5 to P6 for 60 Hz.
Disconnect J5 from P7 for 50 Hz.
Apply the appropriate reconfiguration label.
Replace the control box cover.
Check and adjust voltage as necessary after the frequency has been changed.

Configuring the Controller Using Control Switch adjustment

⚠ In configuration mode the control will not start, prime or display faults.

Remove the insulating connectors from harness connectors CONFIG 1 and CONFIG 2 and connect them together.
Press START to increase the code number or STOP to decrease it one unit each press.
Set the configuration code number to 19 for this genset.
Verify the status lamp blinks one blink, pause, then nine blinks.
Disconnect CONFIG 1 from CONFIG 2 and re-install the insulating connectors.

Disabling Battery Charger adjustment

Disconnect the leads marked B1, B2 and B+ from the quick-connect terminals on battery charging voltage regulator.
Insulate the end of each lead with several wraps of listed electrical insulating tape and tie them neatly into the wiring harness.
Secure the access cover when done.
