Descriptions and Features
The Franklin Electric SubDrive Duplex Alternator allows for two Franklin Electric
SubDrive units to operate on the same water system and share the work load
equally. The Alternator will alternate between the two SubDrive units when the
dened amount of run time has been reached. The Alternator is specically
designed for use with Franklin Electric SubDrive products (see Table 1 above).
Key features of the Alternator include the following:
• Works with entire SubDrive
product family
• Selectable alternate timing
• Pump status indicator lights
• Fault detection
• Fail safe operation
• Manual override push-button
• Alarm circuit contacts
• NEMA 4 enclosure
• Low voltage wiring connections

How It Works
The Franklin Electric SubDrive Duplex Alternator is designed to be part of two
independent SubDrive systems. Below is an example of a typical Alternator
System.
Alternating SubDrive Systems
The Alternator controls which drive is running the system by determining which
pressure sensor each drive sees. The two pressure sensors in the system must
have at least a 3 psi differential. The drive that uses the high set sensor will be in
control of supplying water to the system. The other drive will be on the lower set
sensor and will act as a backup. In the event that the primary drive cannot keep
up with the water demand, the backup drive will automatically start and provide
additional water. After the primary drive has reached its dened amount of run
time, the Alternator will interchange the pressure sensors, thus causing the two
drive units to switch roles.
System Diagnostics
In addition to alternating the two drive systems, the Alternator monitors the
two systems to see if they are meeting the water demand as expected. If a
system is not meeting the water demand as expected, the Alternator will lock
the remaining system in as the primary system, declare a ash code indicating
what kind of fault was found, close the alarm contacts, and not allow further
alternation until the fault is cleared.

Fail Safe Operation
The Alternator is designed so that both SubDrive units are always linked to one
pressure sensor or the other. If the Alternator should fail, the system will turn into
a lead-lag system without the alternate function. Therefore, water will still
be delivered even if the Alternator should fail.
Additional Features
The Alternator has a manual override button for selecting which SubDrive unit
should be the primary system. The Alternator also has four different (push
button) selectable timing modes ranging from 1 hour to 24 hours. These timing
modes are based on the run time of the SubDrive unit. When a unit has run
the selected amount of time, the Alternator automatically interchanges the
primary and backup systems. In addition, the Alternator can be used with any
combination of SubDrive products from Franklin Electric; one model ts all!
s WARNING
!
For the indoor/outdoor transformer note the following:
Risk of fire. If installation involves running wiring through a building
structure, special wiring methods are needed. Consult a qualied electrician.
Not for use with dimmers.
Before Getting Started
s ATTENTION
!
This equipment should be installed by technically qualied personnel.
Installation must comply with Franklin Electric’s recommendations, national
and local electrical codes. Failure to do so may result in electrical shock,
re hazard, unsatisfactory performance, or equipment failure. Installation
information is available through pump manufacturers and distributors, or
directly from Franklin Electric at our toll-free number 1-800-348-2420.
s CAUTION
!
Use the SubDrive Duplex Alternator only with Franklin Electric SubDrive
units as specied in this manual (see Table 1). Use of this unit with Variable
Frequency Drives (VFDs) from other manufacturers may result in damage to
both sets of electronics.

Controller Location Selection
The following recommendations will help in the selection of the proper location
of the Alternator unit.
1. A tee is recommended for mounting the two pressure sensors at
one junction. If a tee is not used, the pressure sensors should
be located within 6 feet (1.8 meters) of the pressure tank to
minimize pressure uctuations. The distance between the
pressure sensors should be kept to a minimum. There should be
no elbows between the tank and the pressure sensors.
2. The unit should be mounted on a sturdy supporting structure
such as a wall or supporting post.
3. When installed properly, the Alternator enclosure is suitable for
indoor or outdoor installations (see Installation Procedure section
for details pg. 9).
4. The Alternator should only be mounted with the wiring end
oriented downward. The controller should not be placed in
direct sunlight.
5. The mounting location should have access to 115 VAC electrical
supply. For outdoor installations the indoor/outdoor transformer
must be connected to a GFCI outlet and follow all National,
State, and Local electrical codes. Ensure that requirements of
NEC 406.8 are met.
6. To assure maximum weather protection, the unit must be
mounted vertically with the cover snaps engaged.

Installation Procedure
1. Disconnect electrical power at the main breaker.
2. Drain the system (if applicable).
3. Install the two SubDrive or Inline units per their installation instructions.
4. Install the two pressure sensors on a tee downstream of the
pressure tank (the pressure tank should be between the pressure
sensors and the pump). The sensors have a ¼-18 National Pipe
Thread (NPT) connection.
5. Mount the Alternator unit in a suitable location using four
mounting screws (not included) as shown in Figure 1 below.

System refer to the Duplex Inline Constant Pressure System Quick Reference
Guide (Appendix 1).

Wiring Connections
1. Verify that the power has been shut off at the main breaker.
2. Open the cover to the Alternator.
3. Drive Connections
Connect a two-conductor pressure sensor cable from Drive 1 to the
Alternator’s terminal block labeled SD1 on the right side. The red and
black wire connections are interchangeable. (See Figure 2 below).
Whichever Drive unit is connected to the SD1 terminal will be the primary
system rst. The Drive unit connected to the SD2 terminal will be the
backup system rst.
A. If connecting to a SubDrive300, use the supplied two-conductor
pressure sensor cable. Cut the terminals off both ends of the red
and black leads from the existing four-conductor cable. Leave
only the Green and White leads linking the pressure shut-off
switch to its connections on the SubDrive300.
B. For all other SubDrives, cut off the quick connect ends and strip
the wire to make a two-conductor cable with stripped leads at
both ends.
4. Repeat step 3 for Drive 2, but connect Drive 2’s pressure sensor cable to
the Alternator’s terminal block labeled SD2 on the right side.
