always disconnect the power
first. Do not smoke or use
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic sump.
Electrical Connections:
The contractor must conform
to the latest requirements of the
National Electrical Code. All
conduit and ca bles shall be in
accordance with NEC Code
NFPA #70. To maintain UL and
CSA ENCL rating, use the same
type UL and CSA weatherproof
con duit hubs when connecting to
this en clo sure. Prior to conducting
any in stal la tion, repair or service
with re gard to the control panel,
refer to the schematic appropriate
for that panel. The schematic will
provide guidance with regard to
the terminal block con nec tions.
CAUTION: A nonmetallic
enclosure does not provide
grounding conduit con nec tions.
Use grounding bush ing and
jumper wires.
Make the Following
Electrical Con nec tions:
a. Connect the pump leads to
the control panel. If pump
is single phase and the panel
has start ca pac i tor, start
relay and run ca pac i tor, it is
critical that the pump leads
be connected prop er ly. The
White, Black, and Red pump
leads must be connected to
the ap pro pri ate terminals
as direct ed by the panel
schematic and the label on
the back panel below the
terminals.
b. Connect the pump heat sensor
and seal failure leads (if
available on the pump) to the
appropriate ter mi nal blocks in
the control panel.
c. Connect all the float control
leads or 4-20mA leads to the
appropriate panel terminals.
Contractor must be very
careful in locating the floats
at the proper elevations. The
maximum dis tance from the
control panel to the floats
is the lesser of l00 feet,
or the maximum distance
rec om mend ed for the pump.
d. Before connecting power to the
control panel, make sure all
con trol switches (e.g. H-O-A
switch) and protective devices
(e.g. breakers) are in the Off
po si tion. Now connect power
to the terminal block or the
circuit break er as directed by
the sche mat ic.
e. Control panel must be
grounded properly per
NEC and/or local codes. To
facilitate this, a ground lug is
provided on the control panel.
The NOVUS 3000 uses five
normally open float switches for
level sensing. When the tank is
empty all of the floats are open.
The lowest float is the low alarm
float. If it is not used the low float
input should be shorted with a
jumper. When the tank is empty
the controller will be in the low
alarm condition. On rising water,
when the level is high enough
to close the low float switch
then the low alarm will go off.
As the level rises the off
float will close and then the
lead float will close. When this
happens the pump controller
will call for the lead pump.
Which pump is the lead, will be
determined by the alternator. If
the alternator is set for pump 1,
then pump 1 will be called. If the
alternator is set for pump 2, then
it will be called. If the alternator
is set in the on position, then for
each pump cycle the lead pump
will change. If one of the pumps
has an existing leak failure, then
the other pump will be called as
the lead. If any pump has existing
temperature failure or is disabled,
then that pump will not be called.
If the lead pump lowers the water
level far enough to open both the
lead and off floats, then the lead
pump will be turned off and the
lead pump changed if alternation
is on. If the water level continues
to rise and closes the lag pump,
then the lag pump will be called.
If the level drops enough to open
the lag, lead, and off floats, then
the two pumps will be turned off.
When both pumps are turned off
there is a 4 second delay between
the first and second pump turning
off. If the water level continues to
rise and closes the high alarm float,
then the high alarm condition will
be set. This will cause the high
alarm relay and light to come on.
This alarm condition will clear
when the level is low enough to
open the high float. Any time a
pump is started an internal timer
is started which will prevent the
other pump from starting for a
period of time which is selected
by one of the option switches on
the bottom of the controller. This
time can be either 6 or 12 seconds.
The controller has three pairs of
inputs for setting pump related
alarms or faults.
1. Check junction box for
moisture. Moisture may cause
chattering of relays/contactors.
2. If pump is single phase with
start capacitor, start relay
and run capacitor in panel.
Check that pump White,
