M2/M3 BFV: FIRE CONTROL SYSTEM - OD1608 - LESSON 2/TASK 3
2.
Test 2730 (ISU Displays and Controls)
Test 2730 tests various ISU eyepiece displays and controls.
It is
performed using the STE test set.
NOTE
During
the
test
procedure,
the
STE
set
communicator (SETCOM) may display instructions
referring to one of several indexes.
The
contents of these indexes will not be reproduced
in this subcourse.
Instead, reference will be
made to the technical manual in which the index
can be found, when needed.
NOTE
During the test procedure, several pathways
develop depending on the results obtained for
individual tests being run.
Not all pathways
will be covered in this subcourse.
One typical
pathway will be used as an example.
When
actually performing the test on the vehicle, be
sure to have the TM 9-2350-252-20-2-1 on hand and
respond to the actual test results observed
during testing.
a. Preparing for Test 2730. Before beginning to run test 2730 on
the ISU displays and controls, make sure that the engine is stopped,
the turret is shut down, and the weapons are unloaded and safe. Then
perform these initial steps:
(1) Hook up the STE-M1/FVS test set to the vehicle distribution
box as described in lesson 2, task 1 on this subcourse (paragraph 4a
beginning on page 66).
(2) Perform the STE self-test (lesson 2, task 1, paragraph 5
beginning on page 71).
(3) If any faults are found during the STE self-test, refer to
the symptom index table in TM 9-4910-751-14-1, page 5-1.
