My Elecraft KPA500 folds back to half-output at 2:1 and goes into the red zone (cautioned as "critical" in the manual) above 2:1.
Hi Kent,
Where would one find the information, as stated above, in the KPA500 Owner's Manual: ?

PS - Elecraft Owner's Manual for the KPA1500 states the followings:
Page 18:
SWR bargraph: The SWR LEDs are green from 1 to 1.5. The 1.5 to 2 LEDs are yellow and the LEDs above 2 are red
Page 27:
The bargraphs are color-coded green for normal, yellow for marginal and red for excessive levels.
Excessive levels may trigger a fault and switch the KPA1500 to STBY
