Maintenance

Servicing the System

Before performing any generator maintenance, always perform the following steps:

1. Set generator’s circuit breaker to its OFF position.

2. Press and hold the control board OFF button.

3. Remove 15 Amp fuse from control board.

4. Utility voltage is present at generator control board.

Disconnect power before servicing control board by removing the fuses from the transfer switch.

5. After all servicing has been completed, replace fuses in transfer switch, replace 15 Amp fuse in control board, set circuit breaker ON and press and hold control board AUTO button.

Service Code Detection System

Reset Service code Detection System The generator may have to run for long periods of time with no operator present. For that reason, the system is equipped with sensors that automatically shut down the generator in the event of potentially damaging conditions, such as low oil pressure, high temperature, over speed, and other conditions.

The generator’s control board shows service code descriptions scrolling across the digital display. The service code descriptions are listed below:

The operator must reset the service code detection system each time it activates. To do so, press the control board OFF button for 5 seconds. Once the display turns off, leave it off for at least 30 seconds. Remedy the service code condition, then return the home generator to service by pressing and holding the control board AUTO button and installing the 15

Amp fuse (if removed).

Not for

This service code is indicated by Low Battery Voltage scrolling across the digital display and a single flash on the wireless monitor. This condition occurs if the battery voltage drops below the preset value. Causes for this problem may be a service code battery or battery charge circuit. See Battery

Charge Circuit , Reproduction specifications, take the battery to a local battery store for analysis. Or contact your local service center for assistance.

Reinstall the battery (replace if necessary - see Battery in

Final Installation Considerations in the installation manual).

Then reset the service code detection system, as described earlier.

Low Oil Pressure

This service code is indicated by Low Oil Pressure scrolling across the digital display and two flashes on the wireless monitor. The unit is equipped with an oil pressure switch that uses normally closed contacts held open by engine oil pressure during operation. Should oil pressure drop below the 8 psi range, switch contacts close and the engine will shut down.

To remedy the low oil pressure condition, add the recommended oil to the FULL mark on the dipstick.

Low Frequency

This service code is indicated by Low Frequency scrolling across the digital display and five flashes on the wireless monitor. This feature protects devices connected to the transfer switch by shutting the generator down if the engine runs slower than 55 Hz for three seconds. This condition is caused by a failed engine component, electronic governor system, or by excessive loads on the generator. To resolve the problem, contact your installer or an authorized dealer.

Engine Overspeed

If the low oil pressure condition still exists, the engine will start, then shut down again. The service code will appear. In this case, contact an authorized dealer.

This service code is indicated by Engine Overspeed scrolling across the digital display and six flashes on the wireless monitor. This condition can be caused by a problem within the electronic governor system.

Under Voltage

The most likely cause of this problem is no fuel supply or incorrect fuel selector setting. See Fuel Selection Switch in the installation manual. Check the internal and external fuel shut off valves to ensure they are fully open. Other causes could be failed spark plug(s), a loose electronic governor connection, a failed engine ignition, or the engine air filter is clogged. You may need to contact your installer for assistance if you can’t remedy these problems.

To resolve the problem, contact your installer or an authorized dealer.

This service code is indicated by Under Voltage scrolling across the digital display and three flashes on the wireless monitor. This condition is caused by a restriction in the fuel flow, the electronic governing system not functioning properly, a broken or disconnected signal lead, a failed alternator winding, the control board circuit breaker is open, or the generator is overloaded.

High Oil Temperature

This service code is indicated by High Oil Temperature scrolling across the digital display and seven flashes on the wireless monitor. The contacts of the temperature switch are normally open. If the engine temperature exceeds a predetermined temperature, the service code is detected and the engine shuts down.

To remedy the problem, contact your installer or an authorized dealer.

Over Voltage

This service code is indicated by Over Voltage scrolling across the digital display and three flashes on the wireless monitor.

This feature protects devices connected to the transfer switch by shutting the generator down if the generator output voltage happens to increase above the preset limit.

This condition is most likely caused by an alternator excitation circuit or a load imbalance. To remedy the problem, contact your installer or an authorized dealer.

Engine Does Not Start

This service code is indicated by the unit will stop cranking.

Not for wireless monitor. This feature prevents the generator from damaging itself if it continually attempts to start in spite of another problem, such as no fuel supply. Each time the system is directed to start, the unit will crank for 10 seconds, pause for 10 seconds, and repeat. If the system does not begin producing electricity after approximately 2 minutes,

Common causes for this condition include running the unit with an access doors removed, obstructed air inlet or exhaust port, or debris in the engine compartment or running unit with roof open.

To resolve the problem, let the engine cool down and remove any accumulated debris and obstructions. Ensure that the access doors are installed and the roof is closed whenever the unit is running. If problem persists, contact your installer or an authorized dealer.

Transfer Switch Service code

This service code is indicated by Transfer Switch Service code scrolling across the digital display (if transfer switch is equipped with service code detection) and eight flashes on the wireless monitor.

The most likely cause of this service code is a blown fuse in Reproduction

No Wireless Communication

This service code is indicated by No Wireless Communication scrolling across the digital display. This condition is caused by an internal error of the wireless system on the control panel.

To resolve this, remove power completely from the control panel by removing the 15 Amp ATO FUSE, then remove utility power from the generator. After 1 minute, apply utility power to the generator, and then replace the 15 Amp ATO FUSE. Put the generator back into Auto mode. If the problem persists, contact your installer or authorized dealer.

Battery Charge Circuit

This service code is indicated by Battery Charge Circuit scrolling across the digital display. The most likely cause is an electrical problem with the control panel. To remedy the problem, contact your installer or an authorized dealer.
