MATCH EQUIPMENT TO
POWER SUPPLY: It is important
always to match the pump motor voltage, phase,
and HP ratings to your control panel and power
supply. Record the motor nameplate HP, voltage
and phase in the Owner Information table on the
cover page. Make sure that the power supply, motor nameplate, and panel nameplate data match.
Incorrect voltage or phase can cause fire, motor
and control damage and voids the warranty.

It is important to use the wiring
diagrams furnished in the manual
and to wire all connections as indicated. Please
refer to Figure 1 on page 4 and pages 9-12.
Motor Lead Connections: Locate the terminal
block labeled T1, T2, T3 and ground screw.
Connect wires to terminal block and route wires
through one of the knock out ports on the bottom
of the panel. There is room allowed to wire with
service loops to avoid wire strain.
Input Power Cable Installation: The main power
cable is connected to the terminal block labeled
L3, L2, and L1. Room is allowed in the panel to
wire with service loops to avoid wire strain.
PaNEl OPERaTION
Operation is with a Hand/Off/Auto (HOA) threeposition switch on the panel cover. The pump may
be started and stopped at the panel cover by setting the switch to the Hand (manual start) or Off
positions. When the three-position switch is in the
Auto position, start and stopping is controlled only
by the wired remote contact or control device.
ChECk ROTaTION
Always verify correct rotation. Correct rotation
is usually indicated on the pump casing. Motor
direction is reversible. Consult pump and motor
manuals for specific instructions.
A full three-phase supply consisting of three individual transformers or one three-phase transformer is recommended. “Open” delta or wye connections using only two transformers can be used,
but are more likely to cause poor performance,
overload tripping or early motor failure due to
current unbalance.
Check the current in each of the three motor leads
and calculate the current unbalance as explained
below.
• If the current unbalance is 2% or less, leave
the leads as connected.

• If the current unbalance is more than 2%,
current readings should be checked on each
leg using each of the three possible hook-ups.
Roll the motor leads across the starter in the
same direction to prevent motor reversal.
To calculate percent of current unbalance (see,
Example below):
1. Add the three-line amp values together.
2. Divide the sum by three, yielding average
current
3. Pick the amp value, which is furthest from
the average current (either high or low).
4. Determine the difference between this amp
value (furthest from average) and the average.
5. Divide the difference by the average. Multi-
ply the result by 100 to determine percent of
unbalance.
Current unbalance should not exceed 5% at service factor load or 10% at rated input load. If the
unbalance cannot be corrected by rolling leads, the
source of the unbalance must be located and corrected. If, on the three possible hookups, the leg
farthest from the average stays on the same power
lead, most of the unbalance is coming from the
power source.
Contact your local power company to resolve
imbalance.

COmbINaTION sTaRTER aNd
OvERlOad RElaY
FloStandard is furnished with a combination
starter and overload relay to protect the motor from overload during start-up or operation.
Panels designed for use on three phase power also
incorporate circuitry that will protect motors from
phase loss or phase imbalance, in addition to overload during start-up or operation.
Figure 2 – Starter/Overload Relay
The following are field adjustments and indications
are available and can be referenced from Figure 2
above:
• Setting Based on Motor Service Factor: For
continuous-rated motors having a service
factor (SF) of 1.0, set the current adjustment
dial to 90% of the motor’s full-load current
(MFLC). For continuous-rated motors having
a service factor of 1.15 to 1.25, set the FLA
dial indicator current to the MFLC.
• Visible Trip Indication: A viewing window on
the front of the solid-state overload relay provides visible trip indication. A yellow marker
appears when the device is tripped.
When the overload relay detects motor current in
excess of 125% of the current adjustment dial setting, the overload contacts open and the optional
auxiliary contacts change state (N.O. contacts
close and N.C. contacts open). The time required
for the overload relay to trip depends upon:
• Current value.
• Time elapsed since last trip.
The phase loss/phase imbalance circuitry can
detect a phase loss and initiate a trip within three
seconds. Phase loss detection extends to a phase
loss in either the primary or the secondary of a
wye-delta or delta-wye transformer. The circuitry
also detects a phase imbalance and initiates a trip
when any phase current drops 25% below or rises
25% above the average of the three phase currents.
Reset Bar: The overload relay is reset by depressing the reset bar on the front of the device. Since
the overload relay trip function is of the “tripfree” design, it cannot be overridden by holding
down the reset bar.
Overload Relay Power On Light: A red LED
indicates that the power necessary to operate the
overload relay protective circuitry is present. This
power is derived from the current flowing in the
motor leads. When sufficient power is extracted to
enable normal operation, the LED blinks. It blinks
faster as the current being monitored increases.
Functional Test: To test for proper operation
of the overload contacts, de-energize the starter
and disconnect the control circuit power. With a
small, flat-blade screwdriver, slide the TEST switch
located on the bottom of the overload relay to the
right. This operates the trip mechanism, opening
the N.C. overload contacts at terminals 95 and 96.
Verify proper operation of the overload contacts,
and then reset the device by depressing the red
RESET bar. Reconnect the control circuit power
and reenergize the starter as required.
Inspecting and Replacing Contacts: Discoloration
and slight pitting do not harm contacts. Do not file
contacts; this wastes contact material. Replace contacts only when worn thin. To inspect or replace
contacts, disconnect all power. Do not remove any
wiring. Loosen the four captive screws holding
the contact actuator to the contact block. Lift the
contact actuator to expose the contacts. Manually
operate the contactor or starter with a screwdriver
by pushing down the contact carrier. There is a
step on the outside of the contact carrier suitable
for this use. Replacement starter contacts may be
obtained from a local electrical supply house.

Loss of Phase/Phase Imbalance: The overload
relay has phase loss and phase imbalance monitoring circuitry. Loss of phase or a phase imbalance
of 25% or more of the average of the three phases
will result in a trip. Disconnect the unit from the
main power supply, find and correct cause for
phase loss of phase imbalance. Possible causes
would be blown fuse(s) or loose wiring connections. Reset the overload relay with the reset bar
on the front of the combination starter. Restart the
pump.
CONTROllER FUNCTIONs
FloStandard is designed to accept a variety of
inputs to function as a pump controller. Pressure
Switches, Level Sensors, Flow Switches, etc. can
be used as a dry contact signal to automatically
start and stop the pump. Caution should be used
to prevent pump cycling when utilizing remote
controllers.
