The red and the green LEDs light if the continuous operation threshold continues for more than 90 secs, and flashes when the excitation is above the continuous operation threshold for fewer than 90 secs.

When voltage fluctuates, the R450’s soft voltage recovery function helps it return to its rated speed faster by supplying a gradual increase in voltage. This function is designed to minimize operating problems.
