2.4.2.4
MIV Valve Drive
The SAM system utilizes one [1] MIV valve drive module to support the operation of each Hale
master intake valve installed in the SAM system.
See paragraph 4.8.4 (page 100) for all other MIV valve drive module information.
2.4.3
System Sensors
The SAM system consists of the sensors described in the following subparagraphs. See the fol-
lowing SAM system diagrams for SAM sensor connectivity and general system level information:
Figure 17 (page 20)
See section 4.6 (page 72) for all other sensor information.
2.4.3.1
Barometric Sensor
The barometric sensor measures atmospheric pressure, which the SAM software uses to calcu-
late the remaining pump capacity (Refer to SAM OIM (FSG-MNL-00210), Figure 36.)
Do NOT attempt to R&R the sensor before seeing paragraph 4.7.1 (page 72) to prevent sensor
damage and for other sensor information.
See paragraph 4.16.2.1 (page 165) to check/test the sensor.
2.4.3.2
Flowmeters
Flowmeters measure individual discharge valve flow. The flow data is used to show flow for that
discharge and the total flow for the truck.
Do NOT attempt to R&R the sensor before seeing paragraph 4.7.2 (page 74) to prevent sensor
damage and for other sensor information.
2.4.3.3
Gearbox Oil Level Sensor (Single Point Level Switch)
The level sensor is physically positioned in the gearbox to alert the SAM operator of a low oil con-
dition. Do NOT relocate or change the sensor attitude.
Do NOT attempt to R&R the sensor before seeing paragraph 4.7.4 (page 80) to prevent sensor
damage and for other sensor information.
2.4.3.4
Pressure Sensors
The SAM system uses two different pressure sensors: The first is used for water and foam con-
centrate tank level indication and the SAM drain assembly to indicate the water column (flex tub-
ing to the top of the onboard water tank) is full of water; The second is used for master intake
and discharge pressures (pump pressure) and for all discharge valves.
Do NOT attempt to R&R the sensor before seeing section 4.7.3 (page 80) to prevent sensor dam-
age and for other sensor information.
2.4.3.5
Temperature Sensors
The SAM system uses a temperature sensor to monitor gearbox oil and pump intakes tempera-
ture. Each sensors resulting output is displayed on the SAM Pump Controller, PUMP INFO screen.
See paragraph 4.15.1 (page 145) to check/test the sensor.
Do NOT attempt to R&R the sensor before seeing paragraph 4.7.5 (page 82) to prevent sensor
damage and for other sensor information.
