4.7.22.1 Load to erect test. To determine conformance to 3.6.12.1.1, 3.6.12.2, and

3.6.12.8.3, the load to erect circuitry shall be verified by opening the cargo hatch and observing successful operation of the erection drive to erect the launcher. It shall be visually verified that the launcher decelerates prior to achieving the erect position, that erection locks deploy and appropriate CPA indicators come on in accordance with table VI.

4.7.22.2 Erection locks during manual procedures. To determine conformance to 3.6.12.2, and 3.6.12.2.1, it shall be verified that erection lock cylinders remain engaged when hydraulic pressure is bled down to the precharge level specified in 3.6.12.7.3 and all ITV weapon station power switches are set to "OFF". The manual hydraulic pump shall be used to raise system indicated pressure to about 1500 psi, and it shall be verified that erection locks retract and that locks then engage when emergency power is turned to "ON".

4.7.22.3 Manual erection test. To determine conformance to 3.6.12.2, 3.6.12.2.1, and

3.6.16.1, the launcher shall be put in the stow position and manually cranked up to erect position.

The maximum torque required shall be less than 20 pound-feet. It shall be verified that after accumulator pressure has been manually pumped to 1200 psi or greater, emergency weapon station power "ON", and launcher position select in "ERECT", that erection locks engage when the launcher erect position is achieved.

4.7.23 Erect to stow test. To determine conformance with 3.6.12.3, stow circuitry, including enable and interrupt circuitry and proper CPA indicators shall be verified. Launcher position indicators shall illuminate in accordance with table VI.

4.7.23.1 Launcher stow test. To determine conformance to 3.6.12.3, it shall be verified that all stow indicators are in accordance with table VI, and that the launcher is resting on its STOW supports.

4.7.24 Load mode tests. To determine conformance to 3.6.12.4 and 3.6.12.8.3, it shall be verified that for CPA AZ and EL indicators - ON and WPM hatch indicator - OFF, the launcher can be driven to the load position. Using an inclinometer, the erection arm angle difference from erect to load shall be measured. It shall be verified that the "ready to load" indicator comes ON with the launcher in the load position. Verify that neither left nor right launch tube RADS can be armed with the launcher in load position.
