How do I restart my generator after clearing an error code during an outage?
This article provides steps for restarting a home standby generator after clearing an error code during an outage.
Environment
This article applies to all home standby generators with an Evolution 1 or Evolution 2 controller: What is the Evolution controller for Generac home standby generators?
Scenario
- In a power outage scenario, the generator automatically senses utility loss and begins the startup and power transfer sequence.
- If a generator was running during the outage, but then shuts down unexpectedly due to an alarm, a red status light on the side will illuminate, and an error code will appear on the generator control panel.
- The error code will need to be addressed before the generator can be restarted and safely returned to load.
To resolve:
1. Go to the front of the generator, lift the lid, and locate the controller on the top right side of the generator
2. Clear the alarm at the control panel by pressing (OFF, ENTER)
3. Turn the generator OFF.
4. Turn the generator disconnect, or main line circuit breaker (MLCB) OFF.
5. At the electrical panel, remove household loads by turning off all circuit breakers in the transfer switch or main electrical panel.
6. Go back to the generator and place it in AUTO mode. If the error code returns and it does not start, contact a service dealer.
7. If error code has cleared, and the generator successfully starts, turn the generator MLCB to ON and proceed with step 8.
8. One at a time, return household loads to generator power by turning on all circuit breakers in the transfer switch or main electrical panel.
