4.6.3.1 Inspection conditions. Unless otherwise specified, the
performance requirements specified for the LCU, Drawing 11830922, shall be
verified using the following test conditions:
a. Input power as specified in the requirement for electrical power
supply.
b. Temperature of 70 + 20F.
c. Measurements will be made using approved functional inspection
equipment and/or standard commercial measuring equipment (see 4.5.4).
Note:
Details such as inputs/outputs, signal levels, pin connections, etc.,
for the tests specified below are in the referenced Section 3
paragraph. This information is a pertinent part of each test
specified.
4.6.3.2 SCAS circuit. Verify that the outputs defined in the specified
requirement of the SCAS circuit occur when the specified inputs are supplied.
4.6.3.3 SCAS command signal input. With Items a and b present as
specified below, verify the output defined in the specified requirement of the
SCAS Command signal input.
a. Fire volts pulse train
Input at Pin J2-Z
Amplitude: 28 V
Pulse duration: 2 ms
Pulse period: 82 ms
b. Interlocked trigger signal Input at Pin J2-r: O Vdc (Ground)
4.6.3.4 SCAS output time delays. Using the fire volts pulse and the
interlocked trigger signal, verify that the SCAS output time delays at Pin
J2-X are as specified in the specified requirement of the SCAS output time
delays.
4.6.3.5 SCAS circuitry with low frequency pulse input. Increase the time
period between the fire volts pulse input In accordance with the specified
requirement for the SCAS circuitry with low frequency pulse input and verify
the specified output voltage change at Pin J2-X.
4.6.3.6 Depression limit circuit, no-limit mode. Using the inputs
defined in the specified requirement for depression limit circuit, no-limit
mode, verify the specified output voltages at Pin JI-D.
4.6.3.7 Depression limit circuit, limit mode. Using the inputs defined
in the specified requirement for depression limit circuit, limit mode, verify
the specified output voltages at Pin JI-D.
