Section III. PRINCIPLES OF OPERATION
The CBPS is a highly mobile battalion aid station designed to be operational in a forward battle area in a
quick time response (under 30 minutes). The CBPS is manned by a crew of four. Two of the crew members
(LMS crew) are inside the LMS and are responsible for operating the electronic controls as well as installing
the internal doors and equipment. The other two members of the crew (cab crew) are the driver and the
navigator. Their responsibilities are to set the ECV for static mode, unload the HMT, connect the 10 kW
TQG to the LMS power panel, install the ABS stakes, install the outside doors on the ABS and other tasks
associated with inflating the ABS. The following provides a basic operational description of the CBPS, its
major components and how they interface with each other.
a. Operational Power. The CBPS is operated using the ECV or the external 10 kW TQG and operates
off both Direct Current (DC) and Alternating Current (AC).
When operating under ECV power, the circuit breaker on the LMS power panel is normally
set to OFF. However, the 10 kW TQG can also be used (circuit breaker ON) to power the AC
electric heaters during low temperature conditions.
ECV System (Internal) Power. When internal power is used (ECV operating), the DC power for
the CBPS is derived directly from the vehicle's electrical system. Two warning indicators on the
rear control panel are used to alert the crew if the engine's oil pressure is low or if the
temperature of the engine's coolant is high (hot).
To set the ECV for static mode, the cab crew puts the vehicle in park, sets the hand brake and
turns the EPG switch ON. The LMS crew turns on the circuit breakers and sets the controls on
the RCP. The EPG controls the idle speed of the ECV engine under varying system load
conditions by comparing the engine speed (via the magnetic pickup on the engine flywheel) with
the settings on the EPG control unit.
