Auxiliary Power Pack A2M1/P2. Provides pressurized hydraulic fluid flow to different
components in ECU when CBPS is operating in external power mode.
(4) Vehicle Control Box 1A4A8. Allows communication between crew members inside ECV cab and
crew members inside LMS. The vehicle control box also contains the switch that enables the
Electronically Programmed Governor (EPG).
(5) EPG Actuator. Part of EPG system, located in ECV engine compartment. EPG actuator receives
signal from EPG control unit to increase ECV engine speed.
(6) Hydraulic Oil Level Indicators. Located on dash of ECV and on rear control panel, lights and
sounds buzzer when hydraulic fluid in the ECU reservoir drops to low levels. System shuts
down when ECU reservoir drops to a critical level, or hydraulic fluid has a loss rate of 2 gpm or
(7) Tachometer/Hour Gage. Located on dash of ECV, monitors engine RPM and number of hours
ECV has run.
(8) EPG Control Unit. Part of EPG system, located in ECV cab. EPG control unit monitors ECV
engine speed, via EPG magnetic pickup, and sends a signal to EPG actuator to increase ECV
(9) EPG Magnetic Pickup. Part of EPG system, located in ECV engine flywheel housing. EPG
magnetic pickup compares speed of ECV engine with changes in the load.
(10) Two Cable Splitters. Located on radio mounting bracket, enables LMS crew to monitor and
operate the radios during all modes of operation.
