Figure 65. SAM Module Locations
The system is designed with this limitation in mind; harnesses are clearly labeled, routed, and
split out so that only the correct harness connector reaches the correct module location (provid-
ing the correct module is installed in that position) to assure proper connections. See Figure 66
for the general appearance of the two types of SAM modules. The module on the left is provided
power via select pins that are located on the two connectors while power for the module on the
right is provided by the stud located between the two connectors.
Figure 66. SAM Modules General Appearance
4.8.1 MatrIIx/Pressure Governor Module
The matrIIx/pressure governor module (Figure 67) connects to the Blue CAN buss, allowing Sen-
try governor functional control of the apparatus engine and providing apparatus information to
the SAM Pump Controller. Additionally, the module translates and integrates throttle, pump en-
gaged, and OK-to-Pump interlock statuses (non CAN signaling) onto the CAN buss (see Figure 14,
page 17). Discrete inputs/outputs are indicated by the direction of the arrow symbol provided
with each signal name (pin) and buss connections are indicated via circles instead of arrows. See
Figure 68.
