Float
Controls
Optional: The LOW WATER /
REDUNDANT OFF float should
be installed just above where the
pump begins to ingest air normally;
this is about the top of the volute.
The OFF float should be installed
about halfway down the pump. If
a LOW WATER / REDUNDANT
OFF float is used, then the off float
should be installed a minimum of
4 inches above the LOW WATER
/ REDUNDANT OFF float.
Install the ON / LEAD floats a
minimum of 4 inches above the
a list of
OFF float. If additional volume

is to be pumped on each cycle
or if the pump running time for
each cycle needs to be increased,
then increase the distance from the
ON / LEAD float to the OFF float
as needed.
Install the HIGH WATER float
4 inches above the ON / LEAD float.
secondary.
For duplex systems install the
LAG / OVERRIDE float 4 inches
above the HIGH WATER float.
On duplex systems where both
pumps have to run on a daily basis
to keep up with the incoming flow,
then the HIGH WATER and the
LAG / OVERRIDE float position
should be reversed.
Seal Fail
Inputs
Each pump has an input for the seal
fail (moisture) sensor commonly
found in submersible pumps. The
controller measures the resistance
of the sensor. In normal operation
the seal fail condition is set if the
resistance is less than 2000 ohms.
One of the option switches can be
used to change this to set the alarm
if the resistance is greater than
2000 ohms. If a seal fail alarm is
set, then that pump is demoted to
lag pump and its seal fail lamp and
output are activated. The seal fail
does not disable the pump.
Temperature
Fail Inputs
Each pump has an input for the
temperature fail sensor often
found in pumps. This sensor
should be shorted if the pump is
good. If the pump overheats, then
this sensor will open. The sensor
is connected to ground and to the
sensor input for that pump. If the
pump controller detects an open
condition in the sensor, then the
temperature fail lamp and output
are activated. The temperature fail
condition will disable the pump.
The controller can be set using
an option switch on the bottom
of the controller to latch up the
temperature fail condition. If this
option is selected, then once a
temperature fail condition is
detected the fault will not clear
until the fault condition is cleared
and the reset push button is pushed
(or external reset input is closed).
If this option is not selected, then
the fault will clear when the sensor
in the pump closes again.
Disable / Pump
Running Inputs
Each pump has an input which has
two possible functions. If the fail
to start test is not activated by an
option switch on the bottom of the
controller, these inputs are pump
disabled. Under this condition, if
this input is shorted to ground, then
that pump will be disabled. If the
fail to start test is activated these
inputs are pump running inputs
and should be shorted to ground
whenever the pump is running.
