3. Check pump run light(s) by
run ning pump(s) in Hand
mode. Check bulb(s) in any
other light(s).
4. With the power off, check
con ti nu ity of all control fuses.
5. Check voltage at primary
and sec ond ary of control
transformer.
6. Check
the
pump
load amps.
7. For 1 phase panels with start
circuit, about 5 seconds after
the pump starts check the
voltage from terminal 1 to
terminal 2 on the start relay
to be sure that the relay has
operated.
The voltage from
terminal 1 to terminal 2 on
the start relay must exceed
10 VAC. For some pumps
the voltage may exceed 400
VAC. If after 5 seconds the
voltage from terminal 1 to
terminal 2 on the start relay
does not exceed 10 VAC, stop
the pump as the start capacitor
may be damaged in about 15
seconds.
If the start relay is not
operating, check the pump and
the system voltage to be sure
that they match. Check the
power wiring to ensure that the
pump is connected properly.
Start the pump once more and
check that the voltage from the
terminal for the black wire to
the white wire is within system
tolerance. Call for help if you
cannot resolve the problem.
8. Check junction boxes for
moisture.

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
may
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

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

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.
