Winding Resistance ± 5%, measured from terminal block.
Pump rated for operation at ± 10% voltage at motor.
OPTIONAL - Temperature sensor cord for 3 phase models is 14/3 SOW, .530 (13.5mm) O.D.
OPTIONAL - Moisture sensor cord is 18/5 SOW, 0.470 (11.9mm) O.D.
OPTIONAL - Moisture and Temperature sensor cord for 3 phase models is 18/5 SOW, 0.470 (11.9mm) O.D.
C-4.2-2) Single Phase (Standard) - The type of in-winding
overload protector used is referred to as an inherent overheating
protector and operates on the combined effect of temperature
and current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or the
load current passing through them becomes too high. It will then
automatically reset and start the pump up after the motor cools
to a safe temperature. In the event of an overload, the source
of this condition should be determined and rectified immediately.
DO NOT LET THE PUMP CYCLE OR RUN IF AN OVERLOAD
CONDITION OCCURS !
If current through the temperature sensor exceeds the values
listed, an intermediate control circuit relay must be used
to reduce the current or the sensor will not work properly.

C-4.3) Moisture Sensors- DS Models: (Optional)
A normally open (N/O) detector is installed in the pump seal
chamber which will detect any moisture present. It is recommended
that this detector be connected in series to an alarm device or the
motor started coil to alert the operator that a moisture detect has
occurred.
