Main Controller
The Main Controller serves as housing for batteries, control switches, status LEDs and system control switches
which can be used to put the unit into different operating modes. In the event the unit has additional Satellite
Controllers and other hardware, the Main Controller serves as the hub for the entire system.
A – Low Voltage Power Block: The low voltage power block is the terminal location for most of
the systems on the M4000 including optional features.
B – High Voltage Power Block: The high voltage power block is the main input point for the
M4000 power system.
C – PCA: The Printed Circuit Assembly (PCA) controls the normal operation of the M4000. The
PCA is also the location of the configuration switches which are used to change the
system from Armed to Jog Mode. The control switches used to jog the system are
also located by the PCA.
D – Status LEDs and Test Switch: The status LEDs indicate normal operation and errors on the
M4000. These lights can be used for troubleshooting the system and verifying certain
conditions. The system test microswitch is also found on the LED board.
E – Batteries: The batteries provide emergency power to the M4000, enabling it to deploy in the
event of primary power loss.
