1.16.13 Mobile Mode, Internal Power, Vent Mode, Full NBC.

The principle difference between the MOBILE and Static Modes is that in the Mobile Mode, the rotating

ECU components, vent (NBC) and recirculation fans, compressor, etc., operate at approximately 1/2 speed.

The slower speed is required because of the reduced volume that requires NBC protection or cooling. The

LMS is much smaller than the combination of the LMS and the ABS that is required in the static mode. This

is accomplished by the hydraulic manifold input solenoid switching from solenoid valve SV2 to solenoid valve

SV1 for the mobile mode. This in turn brings flow control FP1 into the circuit which is set at approximately

1/2 flow. The balance of the hydraulic circuit remains the same as static mode.
