C-3.2-2) Single Phase -

The type of in-winding overload protec-

tor used is referred to as an inherent overheating protector and
operates on the combined effect of temperature and current.
This means that the overload protector will trip out and shut the
pump off if the windings become too hot, or the load current
passing through them becomes too high. It will then automati-
cally reset and start the pump up after the motor cools to a safe
temperature. In the event of an overload, the source of this
condition should be determined and recti

ed immediately.

NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !

If current through the temperature sensor exceeds the values
listed, an intermediate control circuit relay must be used to
reduce the current or the sensor will not work properly.

SECTION: D START-UP OPERATION

D-1) Check Voltage and Phase:

Before operating pump, compare the voltage and phase infor-
mation stamped on the pump identi

cation plate to the available

power.

D-2) Check Pump Rotation:

Before putting pump into service for the

rst time, the motor

rotation must be checked. Improper motor rotation can result
in poor pump performance and can damage the motor and/or
pump. To check the rotation, suspend the pump freely, mo-
mentarily apply power and observe the “kickback”. “Kickback”
should always be in a counter-clockwise direction as viewed
from the top of the pump motor housing.

D-2.1) Incorrect Rotation for Three-Phase Pumps:

In the event that the rotation is incorrect for a three-phase in-
stallation, interchange any two power cable leads at the control
box.

DO NOT

change leads in the cable housing in the motor.

Recheck the “kickback” rotation again by momentarily applying
power.

D-2.2) Incorrect Rotation for Single-Phase Pumps:

In the unlikely event that the rotation is incorrect for a single
phase pump, contact a Barnes Service Center.

D-3) Start-Up Report:

Included at the end of this manual is a start-up report sheet,
this sheet is to be completed as applicable. Return one copy
to Barnes and store the second in the control panel or with
the pump manual if no control panel is used. It is important to
record this data at initial start-up since it will be useful to refer to
should servicing the pump be required in the future.

D-3.1) Identifi cation Plate:

Record the numbers from the pump identi

cation plate on both

START-UP REPORTS provided at the end of the manual for
future reference.

D-3.2) Insulation Test:

Before the pump is put into service, an insulation (megger)
test should be performed on the motor. The resistance values
(ohms) as well as the voltage (volts) and current (amps) should
be recorded on the start-up report.

D-3.3) Pump-Down Test:

After the pump has been properly wired and lowered into the
basin, sump or lift station, it is advisable to check the system by

lling with liquid and allowing the pump to operate through its

pumping cycle. The time needed to empty the system, or pump-
down time along with the volume of water, should be recorded
on the start-up report.
