An electric motor control system includes a motor control circuit for generating a motor control signal and a braking mechanism for adjusting the motor control signal to augment motor losses when the motor control circuit is in a braking mode. In a method of operation, a PI output clock signal is generated in an integrated circuit, and the PI output clock signal is under-sampled in a test latch in the integrated circuit triggered by a test clock signal. The protector body may be configured in a cylindrical geometry having a first end and a second end interconnected by lateral walls and defining a socket. Manifold openings for defining the gas manifold are formed in the first and second separators, and the opening areas of the manifold openings are differently sized.
