Section III. OPERATION UNDER USUAL CONDITIONS
The following procedures shall be performed before the CBPS is put into operation:
a. Perform system PMCS.
b. Check that the set points on the RIB PRESSURE gage located on the rear control panel are set to 1.5
(min.) and 2.9 (max.) psi and that the NBC SHELTER PRESSURE gage set point is set to 0.5 iwg.
When operating with internal power, make sure that the ECV voltmeter, oil indicator, tachometer
and other gages in the vehicle cab are functioning properly and monitor gages during operation.
d. When operating CBPS with internal power (ECV running), record initial and ending readings on
hour meter in log book. One hour of CBPS operation is equivalent to 30 miles of ECV normal
2.24 OPERATING PROCEDURES.
To prevent injury to ears, hearing protection is required.
Do not hit LMS or ABS windows. Windows may crack or break.
Communications between the LMS crew and cab crew are essential. A method of
communication should be established as early as possible (possibly prior to the mission). This
can take the form of voice communications, hand signals, field phones if available, or a
combination of all of these methods.
At times voice communications will be difficult due to high noise level.
See Section V on Remote Radio Operation.
CBPS can operate in the following modes:
a. Mobile. ABS stowed, power supplied by ECV engine. (Refer to para 2.24.1 for usual operation and
para 2.25.1 for NBC operation.)
b. Static - Internal Power. ABS deployed, power supplied by ECV engine. (Refer to para 2.24.2 for usual
operation and para 2.25.2 for full NBC operation.)
Static - External Power. ABS deployed, power supplied by a 10 kW TQG or larger generator. (Refer
to para 2.24.2 for usual operation and para 2.25.2 for full NBC operation.)
2.24.1 Mobile Operation.
Setup procedures that follow apply to a crew of four. Two crew members ride in the ECV cab
and two crew members ride inside the LMS. For explanation purposes, the two-person crew
in the cab is identified as "cab crew" and the two-person crew in the LMS is identified as
Expanded Capacity Vehicle (ECV) Setup.
