Has anyone else experienced the ISO locking up all of the GRX-TVM2s from power glitches?

If the input voltage to the transformer drops to 8VAC or less without going out the power going to the transformer would need to be reset to recover the ISO. If the input voltage drops to between 8VAC and 53VAC the unit will recover when full power is restored.
