Single-Phase PumpSaver

Plus

Model 233P

The Model 233P single-phase PumpSaver

Plus is a pump monitor

designed to protect single-phase pumps from dry-well, dead-head,

jammed impeller, rapid cycle, overvoltage and undervoltage condi-

tions. The PumpSaver

Plus Model 233P protects 230 volt, 2 or 3 wire,

1/3 to 3 hp pumps.

A calibration adjustment allows the Model 233P to be calibrated

to your specic pumping applications, thereby reducing the pos-

sibility of false or nuisance tripping. A proprietary microcontroller

based voltage, power factor and current-sensing circuit constantly

monitors for power uctuations, overcurrent and underload condi-

tions. When an abnormality, such as loss of suction, is detected, the

PumpSaver

Plus deactivates its output relay and directly disconnects

the pump motor. The PumpSaver

Plus then begins its user-selectable

“Restart Delay” (dry-well recovery) timer. When the timer expires or

power is removed and reapplied, the PumpSaver

Plus reactivates its

output relay and allows the pump to turn back on.

An infrared LED communicates directly with a hand-held diagnostic

tool called the Informer (sold separately).

NOTE: The PumpSaver

Plus models have a sensitivity adjust-

ment for the dry-well trip point. After calibration is done, you

can adjust the sensitivity for the dry-well/dead-head trip point

from 70-90% of the full load. This makes the unit even more

adaptable to varying pumping applications. If you have a very

low producing well, you increase the sensitivity closer to the 90%

mark, or if you have a very heavy producing well, you would

decrease the sensitivity around the 70% mark.
