SubDrive/MonoDrive Connect
c. Tighten terminals to 5 in-lbs (0.6 Nm) with a small screwdriver (provided).
d. Torque the fitting as shown in the figure to the right.
NOTE: A 10-foot (3 m) section of pressure sensor cable is provided with the controller, but it is possible
to use similar 22 AWG wire for distances up to 100 feet (30 m) from the pressure sensor. A 100-foot
(30 m) section of pressure sensor cable is available from your local Franklin Electric distributor. Low
capacitance cable must be used if the pressure sensor is being connected with cable not supplied by
Franklin Electric. Cable length longer than 100 feet (30 meters) should not be used as it can cause the
drive to operate incorrectly. (See Accessories section on page 36 for details.)
8. Verify that the SubDrive/MonoDrive unit is properly configured for the horsepower rating of the
motor and pump being used. (See the Pump Sizing section on page 18 for information on
Drive Configuration.)
9. Verify that the SubDrive/MonoDrive is correctly configured for the pressure sensor type being used.
10. Replace the cover. Tighten screw to 10 in-lbs (1.1 Nm).
11. Connect the other end of the pressure sensor cable with the two spade terminals to the
pressure sensor. The connections are interchangeable.
12. Set the pressure tank pre-charge at 70% of the desired water pressure setting. To check the tank's
pre-charge, de-pressurize the water system by opening a tap with the drive off.
(See Table 4 on page 17.)
Measure the tank pre-charge with a pressure gauge at its inflation valve and make the
necessary adjustments.
Additional Control Input/Output Wiring
Built-In Duplex Alternator
The ALTERNATOR terminal supports the built-in Duplex Alternator function of the SubDrive/
MonoDrive Connect controllers. An appropriate Duplex Alternator communication cable should be
used to make the connection between both controllers using this terminal. This Duplex Alternator
cable leads should be wired to this terminal as follows:
(A): Black (same for both drives)
Both drives using the built-in Duplex Alternator function should be wired from the same sub-panel to
ensure proper communication and operation.
See the Accessories section for Duplex Alternator cable ordering information.
Moisture Sensor
The WET SENSOR terminal supports the Franklin Electric Moisture Sensor. The Moisture Sensor
leads should be wired to this terminal as follows:
(+24): Red
The (I+) and (I-) terminals accept an unpowered dry contact relay input and can be used with
other external control switches. Refer to the Advanced Setup section for more information about
configuring this input. See the Accessories section for Moisture Sensor kit ordering information.
