Crane STEP1042L, Installation And Operation Manual

Page: 6 / 26

1.) Flex Hose System (Not Shown)- Connect the flex hose
assembly, as outlined in specifications (to include at least but
not limited to, flex hose, shut-off valve, check valve and fittings),
to the pump discharge. Attach lifting rope, chain or cable to
pump handle. Next lower pump into basin and connect flex
hose assembly to discharge coupling on basin. Now connect
power and control (optional) cables to junction box or control
panel depending on the system design.
2a.) Stainless Rail Package (Not Shown)- The package
system comes complete and ready to place into ground as
outlined in the project specifications. The moveable portion of
the Break Away Fitting (BAF), check valve, piping and guide
bracket comes assembled on the pump along with the lifting
rope. Insert pump bracket and moveable portion of BAF into
the guide channel and lower pump into basin
(DO NOT DROP) .
Now connect power and control (optional) cables to the junction
box or control panel depending on system design.
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 pump is completely 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 OR THE CANADIAN ELECTRIC
CODE, STATE, PROVINCE AND LOCAL CODES.
IMPROPER GROUNDING VOIDS WARRANTY.
C-4.1) Power & 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 all applicable electric codes. It is
recommended that a junction box, be mounted outside the
sump or be of at least Nema 4 (EEMAC-4) construction if
located within the wet well.
DO NOT USE THE POWER OR
CONTROL CABLE TO LIFT PUMP!
C-4.2) Overload Protection:
C-4.2-1) Three Phase (optional)- 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
overtemperature condition and/or the motor starter coil to stop
the pump. In the event of an overtemperature, the source of
this condition should be determined and rectified immediately.
Thermal protection shall not be used as a motor overload
device. A separate motor overload device must be provided in
accordance with NEC or CEC codes.
DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
C-4.2-2) Single Phase (standard)- The type of in-winding
overload protector 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 automatically reset and start the
pump after the motor cools to a safe temperature. 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-4.3) Moisture Sensors: (Optional)
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, check the individual moisture sensor probe leads for
continuity, (
∞ resistance = no moisture ) and the junction
box/control box for moisture content. The above situations may
induce a false signal in the moisture detecting circuit. If none
of the above test prove conclusive, the pump(s) should be
pulled and the source of the failure identified and repaired.
IF A MOISTURE DETECT HAS OCCURRED SCHEDULE
MAINTENANCE AS SOON AS POSSIBLE.
C-4.4) Wire Size:
Consult a qualified electrician for proper wire size if additional
power cable length is required. See table for electrical
information.
