Section II. LAUNCH FRAME ELECTRICAL CONTROL ENCLOSURE MIMIC PANEL
9.2 LAUNCH FRAME ELECTRICAL CONTROL ENCLOSURE
MIMIC PANEL OPERATION
The launch frame electrical control enclosure MIMIC panel is designed to assist in
fault finding the launcher electro-hydraulic system and is an integral part of the
launcher control cabinet. The control cabinet is located on the side of the launch
frame and consists of a cabinet with a protective door. The door offers general
impact damage, with the MIMIC panel being mounted on the inside case. The door
is sealed to offer protection from the external environment.
The MIMIC panel has been designed to visually display which of the solenoids are
activated during any stage of the bridge build, and which are activated at that stage.
This indication is then used to quickly narrow down the identification of any fault to
within a particular circuit or to differentiate whether the fault is electrical or hydraulic.
Description of MIMIC Panel
The MIMIC panel consists of a matrix chart, which cross-references the bridge build
sequence when the required controlling solenoids are energized. Two arrays of
LEDs are used to indicate which solenoids are being energized during a particular
stage in the build sequence. The matrix itself indicating which of the solenoids
should be activated at each stage. The bridge build sequence mode being a direct
reflection of the current selection on the chest pack. The four and two direction
arrows at the bottom of the MIMIC panel reflect the direction the chest pack right and
left hand joysticks are being moved in.
Two different states of solenoid operation exist for each bridge build sequence. The
initial stage occurs when the joystick is in its central position. The MIMIC panel will
display the solenoids, which are being energized prior to the commencement of any
component movement. The second stage occurs once the joystick is moved either
forwards or rearward. The display will change to reflect which solenoids are being
activated during component movement.
Along the top edge of the MIMIC panel there are four groups of LEDs, which display
the supply status, launch controller signals, chest pack signals and the condition of
the interface enclosure signal.
