Figure 2. 25 Launch Frame Electrical Control Enclosure
2.4.6.2
With the enclosure door open the action/solenoid matrix (1) the chest pack joystick
annunciation panel (2) and status caption lights (3) are visible. The matrix enables
fault finding to be carried out. The chest pack joystick annunciation panel shows the
position of both the chest pack joysticks. This enables confirmation of movement of a
joystick and that the signal from the chest pack has arrived at the launch frame
electrical control enclosure.
