GENERAL.
Troubleshooting at operator level is limited to verifying setting of controls, inspecting Chemical and
Biological Protective Shelter (CBPS) System, checking or listening for problems, and taking actions
necessary to keep the system working. Specifically, this includes but is not limited to:
NOTE
These recommended actions are general in nature and were not intended to identify specific
malfunctions that may occur nor all inspections and corrective actions which must be
performed by the operator. If a malfunction occurs and is not corrected by following these
simple steps, immediately notify support maintenance personnel.
a. Verifying that the ECV is in park and the parking brake is set (Static Mode). Problems pertaining to
the ECV should be directed to TM 9-2320-387-10. Problems pertaining to the HMT should be
directed to TM 9-2330-392-14&P.
b. Verifying circuit breakers and switches on control panel are set per Tables 3-2 through 3-9.
c.
Verifying that the proper indicators are ON, that gages are reading properly, and that no alarm
indicators are ON.
d. Inspecting filters for excess dirt or debris.
e.
Inspecting the Air Beam Shelter (ABS), doors and other areas for rips and tears if there is difficulty
in maintaining pressure in the ABS. Operator is responsible for repairing small rips and tears in the
ABS per para 3.13.1.
f.
Inspecting the air beams, flexible hoses, and check valves for leaks if it appears to take longer to
inflate the air beam or that it is obvious that an air beam has a leak.
g. Listening for (normal) changes of engine speed with changes of load, fluctuations in fans/blowers,
hissing sounds indicating an air leak, unusual noises, or other audible sounds of possible problems.
