Mounting the Control Panel
1.
Determine mounting location for panel. If
distance exceeds the length of either the float
switch cables or the pump power cables,
splicing will be required. For outdoor or wet
installation, we recommend the use of a SJE-
Rhombus
®
liquid-tight junction box with liquid-
tight connectors to make required connections.
You must use conduit sealant to prevent
moisture or gases from entering the panel.
2.
Mount control panel with mounting devices
furnished.
3.
Determine conduit entrance locations on
control panel.
NOTE:
Be sure the incoming power, voltage,
amperage, and phase meet the requirements
of the pump motor being installed. If in doubt,
see the pump identification plate for electrical
requirements.
4.
Drill proper size holes for type of connectors
being used.
NOTE:
If using conduit, be sure that it is of
adequate size to pull the pump and switch
cables through.
5.
Attach cable connectors and/or conduit
connectors to control panel.
FOR INSTALLATION WITHOUT
A SPLICE, GO TO STEP 10;
FOR INSTALLATION REQUIRING
A SPLICE, FOLLOW STEPS 6-9.
6.
Determine location for mounting junction box
according to state and local code requirements.
Mount junction box to proper support.
7.
Run conduit to junction box. Drill proper size
holes for the type of conduit used. Attach
connectors to junction box.
Installation Instructions
8.
Identify and label each wire before pulling
through conduit into control panel and junction
box. Make wire splice connections at junction
box.
9.
Firmly tighten all fittings on junction box.
10.
If a junction box is not required, pull cables
through conduit into control panel.
11.
Set motor protective switch:
a) set the dial to match motor full load amps
b) turn dial on motor protective switch to
the ON position
NOTE: Resetting the dial with power applied
to the motor protective switch could start
the motor.
12.
Connect pump wires directly to the motor
contactor terminal positions T1, T2, and T3.
NOTE:
Three phase motors will run in either
direction. Check pump motor before installation
for proper rotation. To correct rotation, change
pump cable connections on any two terminals
T1-T2-T3.
13.
Connect “power-in” conductors to proper
locations: 208/240/480 on 3 position terminal
block.
Install tagged factory wire to
appropriate transformer primary voltage
tap.
VERIFY CORRECT OPERATION OF
CONTROL PANEL AFTER
INSTALLATION IS COMPLETE.
Operations
Three phase simplex control panels are designed
to operate in a three float system as standard.
When all floats are in the open or OFF position,
the panel is inactive. As the liquid level changes
and closes the stop float, the panel remains inac
-
tive until the start float also closes. At this point
the pump will start, assuming the HOA switch is in
the AUTOMATIC mode and the power is ON. The
pump will remain ON until both the stop and start
floats open (return to the OFF position). If the liquid
level travels beyond both the stop and start floats
and reaches the alarm float, the audio/visual alarm
will be activated. The alarm horn can be silenced
by pressing the silence switch.
Alarm System (Horn and Indicator)
When an alarm condition occurs, a red light and
a horn will be activated. If the test/normal/silence
switch is moved to the silence position, the horn will
be silenced. When the alarm condition is cleared,
the alarm system is reset. The alarm system can
be tested by moving the test/normal/silence switch
to the test position.
HOA Switch
A hand-off-automatic switch is provided for the
pump. In the hand mode, the pump will turn on
unless other safety features are employed. In the
automatic mode, the pump will turn on from com-
mands by the float switches.
Motor Protective Switch
A motor protective switch is supplied for the pump
to provide an adjustable overload, branch circuit
protection and disconnect. The overload must be
set in the field. To set the overload, dial the amp
scale to the pump’s full load amps (FLA). If the
FLA’s are unknown, use a calibrated amp me-
ter to measure the pump amperage draw under
loaded conditions. An auxiliary contact is wired in
series with the magnetic contactor coil so that on
an overload trip, the magnetic contactor will be
disabled. In the event of an overload trip, the mo-
tor protective switch must be reset by first turning
the handle counterclockwise to the OFF position
and then turning the handle 90
o
clockwise to the
ON position.
Pump Run Light
The run light will be ON in either the hand or the
automatic mode when the pump is called to run.
Control Power Light
Light will illuminate when the control circuit has
power.
Alarm Power Light
Light will illuminate when the alarm circuit has
power.
Alarm Fuse
Provides alarm circuit protection and provides a
means of disconnecting alarm circuit power.
Control Fuse
Provides control circuit protection and provides a
means of disconnecting control circuit power.
Dry Auxiliary Contacts (optional)
Normally open
- Contacts are open under normal
conditions and closed when alarm condition is
present.
Normally closed
- Contacts are closed under
normal conditions and open when alarm condition
is present.
Both types automatically reset once alarm condi-
tion is cleared.
Seal Failure Circuit and Indicator Light
(Optional)
The seal fail circuit has resistance sensitivity and
will sense the presence of water in the pump seal
chamber. Upon installation, turn the sensitivity dial
on the seal fail module to the point where the light
turns on, then dial back slowly until the light turns
off. If water enters the seal chamber at this point,
the seal chamber circuit will sense a change in
resistance. After a short time delay, the indicator
light will turn on. When the condition is cleared, the
relay will de-energize and the indicator light will turn
off. The seal fail relay has a sensitivity adjustment
so that false readings may be tuned out.
Thermal Cutout (Optional)
The thermal cutout circuit is wired in series with
the magnetic contactor coil. If the pump’s thermal
switch opens on high temperature, the magnetic
contactor will turn off and stop the pump. When
the thermal switch cools and closes, the magnetic
contactor will turn on if the pump is called to run.
