Generac — Over Speed (Shutdown Alarm)

For these Generac models: EcoGen 6kW Generator, GT-530.

Applies to: Generac Ecogen 6Kw Generator, Generac Gt 530

Procedure

1. 3000 RPM for three (3) seconds or 3300 RPM immediately. This feature protects the generator from damage by shutting it down if it happens to run faster than the preset limit. This protection also prevents the generator from supplying an output that could potentially damage appliances connected to the generator circuit. Contact the nearest Dealer if this failure occurs. RPM Sense Loss (Shutdown Alarm) During cranking, if the Control Board does not see a valid RPM signal within three (3) seconds, it will shut down and lock out on RPM sense loss. While engine is running, if RPM signal is lost for one (1) second the Control Board will shut the engine down, wait
2. 15 seconds, then re-crank the engine. If no RPM signal is detected within the first three (3) seconds of cranking, the Control Board will shut the engine down and latch out on RPM sensor loss. If the RPM signal is detected, the engine will start and run normally. If the RPM signal is subsequently lost again, the Control Board will try one more re-crank attempt before latching out and displaying the RPM sensor failure message. Under-frequency (Shutdown Alarm) After starting, if the generator stays under frequency for more than
3. 30 seconds it will shut down. The under-frequency setting is 55 Hz. Internal Fault (Shutdown Alarm) This alarm cannot be cleared, call service dealer. Undervoltage (Shutdown Alarm) If the generator voltage falls below 85% of nominal for more than
4. 15 seconds, it shuts down. Overvoltage (Shutdown Alarm) If the generator voltage rises above 110% of rating for greater than three (3) seconds, an alarm will be issued and the unit will shut down. If the generator voltage rises above 130% of rating for greater than
5. 0.5 seconds, an alarm will be issued and the unit will shut down. Clear Alarm Clear the alarm by setting the AUTO/OFF/MANUAL switch to the OFF position. Press the ENTER key to unlatch any active fault and clear the corresponding alarm message.
6. 3.5.2 WARNINGS Second Priority (Non-latching) Displayed on the control panel and the external yellow LED (V-twins only). Warnings automati- cally clear when the monitored condition goes away. Warnings are recorded in the alarm log. Warnings cannot cause shutdowns. Low Battery The Control Board monitors battery voltage and displays a warn- ing if the battery voltage falls below 11.9 volts for one (1) minute. Warning is automatically cleared if the battery voltage rises above
7. 12.4 volts. Battery voltage is not monitored during the crank cycle.
8. 3.5.3 MAINTENANCE ALERTS Third priority Maintenance Message When a maintenance period expires, a warning message will be displayed. The alert can be reset by pressing the Enter key, which will cause the user to be prompted to confirm the action. Resetting will clear the alert and reset the maintenance counters for all conditions annunciated. The history log will record the alert. The maintenance counter will not accumulate without battery power. Once battery power is restored, the set time prompt will be displayed. The maintenance counters will be adjusted to the new time and date. NOTE: Since most maintenance alerts will occur at the same time (most have 500 hour or two (2) year intervals), only one will appear on the display at any one time. Once the first alert is cleared, the next active alert will be displayed. Operation
