FBL2360 exception fault pattern

I have a FBL2360 motor controller. When I power up the unit (with no voltage to the motor inputs) I see the following pattern on the status led: three short blinks, one long on every two seconds. The data sheet does not have description for this pattern. The Robo Utility shows an under voltage fault (which I expect because no motor voltage). But under voltage is two blinks not three. Is it possible that this is a combination of under voltage and power stage off ( 2 blinks + 1 blink)? I am using the latest firmware.

It's an undervoltage error status. I will make sure we update our documentation.
