Crane BARNES 6SE-EHA Series, Installation And Operation Manual

Page: 6 / 22

Make sure the rails are in a true vertical position so the pump
will clear the access opening and will slide freely down the rails
into place on the discharge stationary fitting. Once the rails are
in proper alignment, bolt the base elbow into the floor of the
station and connect the discharge pipe to the elbow.
Connect the movable portion and other supplied fittings of the
BAF onto the pump and lower into wet well. See the Break
Away Fitting manual for more information.
C-3) Liquid Level Controls:
The level controls are to be supported by a mounting bracket
that is attached to the sump wall, cover or junction box. Cord
grips are used to hold the cords in place on the mounting
bracket. The control level can be changed by loosening the grip
and adjusting the cord length as per the plans and
specifications. Be certain that the level controls cannot hang
up or foul in it’s swing and that the entire pump is still
submerged when the level control is in the "Off" mode.
C-4) Electrical Connections:
WARNING!
ALL MODEL PUMPS AND CONTROL PANELS MUST
BE PROPERLY GROUNDED PER THE NATIONAL
ELECTRIC CODE, STATE AND LOCAL CODES.
IMPROPER GROUNDING VOIDS WARRANTY.
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application. Any
splice between the pump and the control panel must be made
in accordance with the National Electric Code and all applicable
state and local electric codes. It is recommended that a junction
box be mounted outside the sump or be of at least Nema 4
construction if located within the wet well.
Do not use the power cable to lift pump.
NOTE:
The white wire is NOT a neutral or ground lead, but a
power carrying conductor.
C-4.2) Control Cable:
The cord assembly mounted to the pump must not be modified
in any way except for shortening to a specific application. Any
splice between the pump and the control panel must be made
in accordance with the National Electric Code and all applicable
state and local electric codes. It is recommended that a junction
box be mounted outside the sump or be of at least Nema 4
construction if located within the wet well.
Do not use the
control cable to lift pump.
NOTE:
The white wire is NOT a neutral or ground lead, but a
power carrying conductor.
C-4.3) Wire Size:
If additional cable is required consult a qualified electrician for
proper wire size. See table for further electrical information.
C-4.4) Overload Protection:
The normally closed (N/C) thermal sensor is embedded in the
motor windings and will detect excessive heat in the event an
overload condition occurs. The thermal sensor will trip when
the windings become too hot and will automatically reset itself
when the pump motor cools to a safe temperature. It is
recommended that the thermal sensor be connected in series
to an alarm device to alert the operator of an overload condition,
and/or the motor starter coil to stop the pump. In the event of
an overload, the source of this condition should be determined
and rectified immediately.
DO 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.

C-4.5 Moisture Sensors:
A normally open (N/O) detector is installed in the pump seal
chamber which will detect any moisture present. It is
recommended that this detector be connected in series to an
alarm device or the motor starter coil to alert the operator that
a moisture detect has occurred. In the event of a moisture
detect, the pump should be pulled and the source of the failure
located and repaired.
IF A MOISTURE DETECT HAS
OCCURRED, SCHEDULE MAINTENANCE AS SOON AS
POSSIBLE !
