Raceway. Secures CBPS cable assemblies.
Rear Light Box Assembly 1A4A7. Lights the aft LMS crew area.
Inverter 1A4A13. Provides power to outlets on the receptacle panel. The inverter receives 24
Vdc from the ECV electrical system and outputs 115 Vac to the CBPS.
Converter 1A4A14. Allows power from the 10 kW TQG to operate the CBPS. The converter
receives 208 Vac from the 10 kW TQG (or other 208 Vac, 3-phase power 10 kW TQG or greater)
and outputs 24 Vdc for the CBPS.
The Electronic Control Console (ECC) comprises the rear control panel and the power mode
Rear Control Panel 1A4A4. Contains controls and indicators for CBPS deployment and
operation. Controls heating and cooling temperatures within the CBPS through the
temperature control unit.
Power Mode Switch 1A4A4S1. Selects either ECV or an external power source to operate the
Forward Light Box Assembly 1A4A5. Lights the forward LMS crew area.
Control Box Assembly 1A4A18. Allows communication between the LMS crew and the cab crew.
Temperature control knob allows the LMS crew control of internal temperature during mobile
Relay Box 1A4A17. Located in passenger side MOPP gear storage box, supplies +24 Vdc to the
ECU. Contains the components that provide the venting, heating, cooling, and air filtration
equipment. Also provides the air needed to inflate the air beams and to generate the over
pressure (positive pressure) inside the CBPS.
Intake Fan (Vent/NBC). Hydraulic driven fan used to draw outside air into the ECU.
Condenser Fan. Hydraulic driven fan used to cool the condenser coil and hydraulic fluid when
the Environmental Support System (ESS) mode selector switch on the Electronic Control
Console (ECC) is set to COOL or VENT.
Recirculation Fan. Draws in air from the NBC filters and from the return vent duct on the
driver side of the LMS. The air is then directed towards the cooling/heating coils.
Compressor. Consists of an air conditioner compressor used to cool the CBPS when the ESS
mode selector switch on the ECC is set to COOL.
Rib Blower. Consists of a hydraulic driven ring compressor fan used to supply air to the air
Manifold. Directs and controls the pressure and flow of the hydraulic fluid through ports to the
components of the ECU as selected by the controls on the ECC.
Hydraulic Fluid Reservoir. Holds 13 gallons of the system's 22 gallons of hydraulic fluid. A fluid
level gage on the front of the reservoir provides a visual indication of the hydraulic fluid level.
The reservoir also contains a strainer in the fill cap that filters the hydraulic fluid as it enters
