IMPORTANT! - The overload will then
automatically reset and start the
pump up after the motor cools to a
safe temperature. In the event of an
o verload, the source of this condition
should be determined and corrected
immediately.
WARNING
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
Three Phase - The Normally Closed
(N/C) thermal sensor is embedded in
the motor windings and will detect
excessive heat in the event an
overload
condition
thermal sensor will trip when the
windings become too hot and will
automatically reset 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 overload condition, and/or the
motor starter coil to stop the pump.
In the event of an overload, the
source of this condition should be
determined and repaired.
WARNING
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
Moisture Sensors - A normally open
(N/O) sensor rated of 1 watt @330K
ohms, 500 volt, is installed in the
p ump seal chamber which will detect
any
moisture
present.
r ecommended that this detector be
wired in series to an alarm device or
motor starter coil to alert the
operator that a moisture detect has
occurred. In the event of a moisture
detect, check the individual moisture

4. Insulation Test - An insulation
(megger) test should be performed
on the motor. Before the pump is put
into service. The resistance values
(ohms) as well as the voltage (volts)
and current (amps) should be
recorded.
5. Pump-Down Test - Be sure pump
has been properly wired, lowered
into the basin, sump or lift station,
check the system by filling with liquid
and allowing the pump to operate
through its pumping cycle. The time
needed to empty the system, or
pump-down time along with the
volume of water, should be recorded.

required.
