Placing the control switches in the position corresponding the the above modes opens solenoid valves SV2
and SV6 and closes solenoid valve SV9 and valve PD1 by applying +24 Vdc to the coils. This allows some
portion of the total hydraulic fluid flow to bypass the NBC fan motor, M3. Flow control valve FP2 is used to
regulate the flow and hence the speed of the NBC fan motor whenever the control switches are in the non-
NBC mode. All other functions are as previously described.
