Pressure Sensor Connections .
7.
A. Connect the supplied four-conductor cable stripped leads to the
alternator's terminal block labeled "Pressure Sensors".
B. Connect the red and black leads to the PS-HI part of the
block. The red and black wire connections are interchangeable.
C. Connect the white and green leads to the PS-LO part of the
block. The green and white wire connections are interchangeable.
D. Connect the other end of the four-conductor cable with the
fork terminals to the two pressure sensors.
E. Connect the red and black wires to the "high" set pressure
sensor. Connect the stripped ends of the red and black wires
to the alternator (PS-HI). The red and black wire connections
are interchangeable.
F. Connect the green and white wires to the "low" set pressure
sensor. Connect the stripped ends of the green and white wires to
the alternator (PS-LO). The green and white wire connections
are interchangeable. (See Figure 3 pg. 11).
8. The two pressure sensors communicate the system pressure to the
SubDrive units. The alternator requires that the pressure sensors have
at least a 3 psi differential. The sensor connected to the alternator's
PS-HI terminal must be the one set higher than the other sensor. The
sensors are preset at the factory to 50 psi, but must be adjusted by the
installer using the following procedure:
A. Remove the rubber end-cap (See Figure 3 on page 11).
B. Using a 7/32" Allen wrench, turn the adjusting screw clockwise
to increase the pressure and counterclockwise to decrease the
pressure. The adjustment range is between 25 and 80 psi (1/4
turn = approximately 3 psi).
C. Replace the rubber end cap.
D. Cover the pressure sensor terminals with the rubber boot
(See Figure 3 on page 11).
Note: If the pressure sensors are not adjusted properly or connected to the
wrong terminals on the alternator the unit may not function properly. Make sure
that the PS-HI terminal is connected to the pressure sensor that is set higher
than the other pressure sensor.

CAUTION
When increasing the pressure, do not exceed the mechanical stop on the
pressure sensor or 80 psi . The pressure sensor may be damaged .
