SubMonitor Motor Protection System
The SubMonitor Motor Protection System represents the ultimate in protection for the three phase
submersible motors used in the Giant Fountain. The submersible motor and the SubMonitor system
are both manufactured by Franklin Electric.
Digital electronics has made it possible to develop a unique programmed system capable of detecting
overloads, underloads, overvoltage, undervoltage, unbalanced currents, chattering contacts, and
phase reversal. Operates with the Subtrol-equipped submersible motor to provide motor overheat
protection. SubMonitor turns off the submersible motor when any of these faults occur and provides
a visual display of the fault condition and status which is recorded in the system’s history. When the
Giant Fountain is in operation the SubMonitor monitors and displays the three phase voltages, three
phase currents, and the pump status.
The SubMonitor Motor Protection System will come prewired and programmed in the Giant Foun-
tain Power Control Center from the factory. The programming can be verified by following the
“Quick Guide to Setup” section in the Franklin SubMonitor Installation & Operation Manual. See
Table 1 for the settings of each motor rating.All other programmable settings should remain at the
default settings.

WARNING: This equipment should be installed by a technically qualified electrician in compliance
with national and local electrical codes.
Before Installing the SubMonitor System
1. Read both manuals thoroughly.
2. Be sure the incoming power supply is turned off before working on motor or controls.
WARNING: SubMonitor is NOT compatible with phase converters, reduced voltage starters or
variable-speed inverter drives.
WARNING: The Warranty is VOID if the SubMonitor program settings are changed without first
consulting with Otterbine.

SubMonitor Submersible
Pump Motor Protection System
Franklin’s SubMonitor is an easy to use, programmable protection device
for Franklin Electric three phase submersible motors.
SubMonitor’s features provide advanced protection for submersible motors:
• SubMonitor operates over the full range of three phase motor
voltages, 200 - 575 volts, 50 and 60 Hz.
• Operates on motors with service factor current rating of 3 amps
through 359 amps - no external current transformers required.
• Protects motors and pumps from overloads, underloads,
overvoltage, undervoltage, unbalanced currents, chattering contacts,
and phase reversal.
• Operates with a Subtrol-equipped submersible motor to provide
motor overheat protection.
• Monitors and displays three phase voltages, three phase currents,
and pump status.
• When a fault occurs, displays the fault conditions and status.
• Records and displays the history of up to 502 fault trip events, plus
records changes to programmable parameters.
• Records total pump operating time.
• Features a detachable display unit which may be mounted on the
front of a panel for viewing operating status.
• Includes the option of password protection to avoid tampering.
• Easy mounting with DIN rail mounts.
• Totally integrated unit - current transformers are built in.
Simple Programming
SubMonitor has been pre-programmed with default settings for submersible
motors and pumps. Set-up is as simple as setting the motor ratings - voltage,
Hertz, and SF max amps.
Additional programming options can be selected if desired to customize the
features and levels of protection. See page 7 for an overview of the menu
structure and page 12 for a full list of programmable options.
All programming set-up can be made prior to installing at the field site by
connecting 230 volts single phase between voltage inputs L1 and L3 of
SubMonitor and entering the motor data and any other options.

WARNING: Hazardous Voltage.
Electrical shock can cause death or serious personal injury.
This equipment should be installed by technically qualified personnel.
Failure to install in compliance with national and local electrical codes
and within Franklin Electric recommendations may result in electrical
shock or fire hazard, unsatisfactory performance, or equipment failure.

SubMonitor Wiring
1. Read this section of the manual thoroughly.
2. Disconnect power & verify that power is off before installing SubMonitor.
3. Install SubMonitor as illustrated in the wiring diagram in Figure 1.
SubMonitor may be mounted above or below the contactor as shown. To
use the DIN rail mount, first attach the DIN rail clip to the bottom of the
base unit. Then secure the SubMonitor to the DIN rail. Attach to the top
of the rail first, then apply downward pressure until the DIN clip snaps
into the bottom of the rail.
4. Connect three phase power leads to the plug-in connector L1, L2,
and L3 terminals as shown in figure 2. Wire strip length is 5/16” (8mm).
The L1, L2, L3 connections must be made to the line side of the
cables passing through the sensor coils as shown in figure 2. (This is
because the overheat signal from the motor must first pass through the
sensor coils, then into the L1, L2, and L3 terminals of SubMonitor).
5. Connect the control circuit wires to the M1 and M2 plug-in connector
terminals, and signal circuit wires to the A1 and A2 plug-in connector
terminals (Figure 3). Tighten all terminals to 4.5 in-lbs and install the plug-
in connectors into SubMonitor (plugs are keyed to avoid misconnection).
6. Pass the T1, T2, and T3 motor power leads through the sensor coils in
the base unit.
7. NOTE: 6-lead Wye-Delta motors - for a 6-lead motor with a Wye-Delta
control panel, each sensor coil must encircle a pair of leads which connect
to the same line in the delta connection, such as T1-T6; T2-T4 or T3-T5.
8. As an option, the SubMonitor display unit is detachable and can be
mounted on the exterior of the panel door (requires a small punch-out,
gasket and two screw holes). Use the extension cable provided in the kit
to connect the base unit to the display unit.
Lightning Arrestor
1. Install the lightning arrestor and connect line leads to the line side of the
contactor as shown in Figure 4.
2. The lightning arrestor ground lead must be connected to water strata
ground to provide suitable surge protection. Connect metal-to-metal to
well casing, drop pipe, or to the submersible motor with wire the same
size as drop cable wires.
NOTE: Refer to Franklin Electric
Submersible Motor, Application,
Installation and Maintenance (AIM)
manual for further discussion of
lightning protection.

Quick Guide to Setup
Points 1 through 3 below describe navigation: how to get around among the
two menus and several screens. Point 4 describes how to change a parameter.
1. On initial power-up, the control circuit will be locked out until the
motor voltage and SF Amps are set. After a 30 second delay while
data sync is completed, the monitor screen will report SF Amps Set Too
High: Locked Out*. Notice MENU in the lower right corner—the arrow
indicates that pressing the knob will take you to the menu Basic Setup.
2. From Basic Setup,rotate to Select Motor and press, and you will
arrive at the Select Motor screen where you can set motor Hz, volts, and
SF Amps (read point 4 below). Set the SF Amps to match the motor SF
Max Amps by adjusting each digit individually. When you are done with
this screen, rotate to OK and press, thereby going back to
Basic Setup.
3. Note that selecting Detailed Setup takes you to a longer menu with
items that are lettered. Select Back: Basic Setup to return to Basic
Setup. Refer to charts on page 7 and page 10 for structure and available
options of menus.
4. When you are on a selected screen of either Basic Setup or Detailed
Setup and you want to change a setting:
a. Rotate the knob until the arrow points to the item to be changed.
b. Press the knob and the arrow will blink. Turning the knob now
changes the value of the item.
c. When the item is correctly adjusted, press the knob and the arrow
stops blinking.
d. You can now rotate the knob to another item on the screen.
Selecting OK returns you to the parent menu.
SubMonitor is now set up to protect your motor and pump, and will allow
the motor to start when you return to the Monitor screen and select Manual
Reset. After any Manual Reset there is a one minute off-time delay
before the motor starts.
Note that the signal circuit and red Fault LED are ON until the motor data is
entered and Manual Reset is pressed.
* Phase Reversal—SubMonitor has a built in phase sequence meter. If
initial power up displays Phase Reversal, the incoming voltage at
SubMonitor’s L1,L2, L3 terminals is negative sequence, and the contactor
is locked out until the phase sequence is corrected.
Figure 2 on page 4 shows SubMonitor inputs L1, L2, and L3 connected
to motor leads T1, T2, and T3 respectively. While this order is not critical
for operation of SubMonitor, it should provide proper motor rotation with
positive sequence line voltage.

Event History
Information Logged
Up to 502 events can be logged and stored in the display unit in a rolling
data set. Information stored includes:
• Event (trip fault, power interruption, etc)
• Time of event (pump run time)
• 3 motor currents
• 3 line voltages
Reviewing Events
• Before events can be reviewed, a valid password must be entered (if
the password is other than 0 0 0).
• Each event is represented by one screen of information.
• Each event is numbered (0-511).
• Each event has a time stamp displayed in days (0-1165), hours (0-23),
minutes (0.0-59.9).The time stamp displayed is the total pump run time.
• You can sequence through the events by turning the knob; CCW goes
backward in time, CW goes forward in time.
• Entering the Event Review system is itself an event that is logged.
This event provides the Total (pump) Run Time. This will be the first
event shown upon entry into the Event History, and is identified as
“Total Run Time”.
Events Logged
• Total Run Time (always the most recent event)
• Power Up Delay (records power interruptions)
• Tripped : Underload
• Tripped : Overload
• Tripped : Unbalance
• Tripped : Overheat

Unbalance, overvoltage, and undervoltage trips are disabled.
Key to Parameters in Event History

11
Note: The SubMonitor is not
compatible with variable frequency
drives, electronic phase converters, or
solid state soft starters. These devices
will cause nuisance tripping of the
motor overheat fault, or may cause
damage to SubMonitor components.
Reduced voltage starters may be used
with SubMonitor if they are bypassed
during normal running condition
(Figure 5), and if the starting time does
not exceed 3 seconds.
Power Factor or Surge Capacitor—
across-the-line capacitors for
either power factor correction or
surge protection may be used with
SubMonitor. If used, these capacitors
must be connected to the power
supply lines before these lines pass
through the SubMonitor sensor coil
windows or motor overheat protection
may be lost.
Other Features
Reset
The receiver will not allow a reset for several minutes after a fault trip,
depending on the programmed reset time and fault mode. This allows time
for the motor to cool before it is restarted after a problem has occurred. Any
Manual Reset causes the motor to restart in exactly one minute.
Operation without the Display Unit
After the Select Motor parameters are entered (volts, Hz, and SF Amps),
the base unit of SubMonitor provides full motor protection even when the
Display Unit is disconnected.
When operating with a Base Unit only:
• A “run enable” condition is indicated by a green LED
• A trip condition is indicated by a red Fault LED
• Manual reset is initiated by pressing the Reset Switch
• The Event History is not recorded (total run time is recorded).
