4.7.3.1.1 Legacy AB Valve Pressure Sensor
Legacy SAM systems utilized Akron Brass pressure sensors (Figure 49). When these sensors fail,
replacement with the newer Hale sensor is required. The legacy and new sensor wiring is the
same. See Table 29 (page 75) and Table 33.

From Pressure Sensor Pin To Valve Driver Pressure Connector Pin
A (Pressure Signal) 1 Pressure Signal [Input]
B (Power) 4 Power [Output]
C (Ground) 3 Ground [Output]
Use the AB Swing-out Valve Pressure Sensor procedure (above) for the legacy Akron Brass pres-
sure sensors.
Do NOT overtighten pressure sensor more than an additional 1/4 turn from hand tight.
NOTE
The legacy AB sensor is rated to 600 psi (41 bar).
4.7.3.2 Pump Master Pressure Sensors
The SAM system utilizes the same Hale pressure sensors as the discharge valves except the sen-
sors are mounted on the operator panel or pump body.
NOTE
Hale recommends installing these sensors on the rear of the Class 1 test port adapter
(PRESSURE/VACUUM) behind the operator panel. (Provides best vibration isolation.)
However, most SAM units have installed the discharge sensor in any of the upper pump body
pressure taps and the intake pressure sensor in any of the upper pump body vacuum taps. (Re-
fer to FSG-PL-01509 or FSG-PL-01510 for pressure/vacuum taps locations.) Electrically the sen-
sor connects to the MatrIIX/Pressure Governor Module (see Table 30, page 76).
NOTE
If the MatrIIx Pressure Governor module was replaced perform the pressure calibration
using the SAM Pump Controller instead of the SAM Control Center and configure/setup
the module parameters at the same time. (See paragraph 6.17, page 195.)
If a pump pressure sensor fails or is damaged; replace the sensor using the AB Swing-out Valve
Pressure Sensor procedure. (See paragraph 4.7.3.1 on page 76.)
