Standby Generator Exercise Cycles
Many standby generators periodically start themselves for an exercise cycle. This helps verify basic startup operation but does not prove that every part of the system is problem-free.
What exercise can show
An exercise cycle can reveal a failure to start, controller fault or other obvious issue before an outage.
What exercise does not replace
It does not replace engine maintenance, battery evaluation, fuel-system checks, transfer-system inspection or other manufacturer-required service.
Pay attention to new alerts
If the controller begins reporting a warning or the generator fails its expected exercise, check the model-specific manual and arrange service when appropriate.
