Xylem II 231 P INSIDER - Manual

The PumpSaver
®
Plus Model 231-P-INSIDER fits inside 1/3 – 1hp, 230V Franklin™, Pentek™, or
CentriPro™ control boxes. PumpSavers are designed to protect single-phase pumps from dry-well,
dead-head, rapid-cycling, jammed impeller, and over/undervoltage conditions. Typical applications
include residential waterwells, commercial waterwells, irrigation wells, and golf course and other
sprinkler systems.
CONNECTIONS
Refer to specific connection instructions depending on the particular control box being used:
Franklin™ control box – page 3
Pentek™ control box – page 5
CentriPro™ control box – page 7
CALIBRATION / SETTINGS
1. Turn RESTART DELAY/CALIBRATION to the CAL position and close the box cover.
2. Apply power to the system. The pump should run for approximately 10 seconds and then shut
off—this indicates the Model 231-P INSIDER has calibrated.
3. Remove power from the system. Open the control box and set the appropriate dry-well recovery
time with the RESTART DELAY / CALIBRATION knob.
4. Shut the control box and re-apply power to the system.
OPERATION
The Model 231-P-INSIDER monitors pump load in amps and kilowatts. When the current (amps)
exceeds approximately 125% of calibrated current, or power (kW) drops below the adjustable
underload trip point, the 231-P-INSIDER—after the trip delay—will turn off the pump. The 231-P-
INSIDER will automatically restart the pump after the selected restart delay time.
The calibration is stored in permanent memory. The PumpSaver
®
Plus does not need to be
recalibrated if power is lost.
SENSITIVITY
The Model 231-P-INSIDER has an adjustment knob to set the underload trip sensitivity. Setting
SENSITIVITY to the middle position (straight up) is equivalent to SymCom’s standard underload
trip level. Adjust the SENSITIVITY knob to increase/decrease underload sensitivity up to
approximately ±10% of the standard trip. It may be necessary to increase the sensitivity if the
PumpSaver
®
Plus does not trip on dry-run or dead-head or it is known that the water level in the
well is very low relative to the pumps capabilities.
WARNING: Decreasing the SENSITIVITY may compromise the PumpSaver’s ability to
detect dry-run and/or dead-head conditions.
