Protection Relays

Motor and Pump Protection

111P / 233P SERIES

Single-Phase PumpSaver

Description

The 111P (115 volt, ¹⁄³ to 1hp), 233P-1.5 (230 volt, ¹⁄³ to 1.5hp),

and 233P (230 volt, ¹⁄³ to 3hp) single-phase PumpSaver

relays

protect pumps from dry-well, dead-head, jammed impeller,

rapid-cycling, and overvoltage/undervoltage, whether the

pressure switch is mounted before or after our unit.

A calibration process allows the relay to be calibrated to your

specific pumping application, thereby reducing the possibility of

false or nuisance tripping. A proprietary microcontroller based

voltage, power factor and current-sensing circuit constantly

monitors for power fluctuations, overcurrent and underload

conditions. When an abnormality, such as loss of suction, is

detected, the relay deactivates its output relay and directly

disconnects the pump motor and begins its user-selectable

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

expires or power is removed and reapplied, the unit 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). The

Informer displays parameters including calibration points, trip

points, run time and last faults.

Special considerations for pump cables larger than #10

AWG*:

In some cases where larger motors are installed with

deep set pumps, pump cables are used that exceed the relay’s

terminal size. In these conditions, a short splice of #10 AWG or

#12 AWG may be a solution at the control box.

*All local, state and national electric codes should be followed when applying this solution.

NOTE: The 111P / 233P Series relays have a sensitivity adjustment 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.
