Operation - SymCom PumpSaver Plus 233-P Installation Instructions Manual

OPERATION

The Model 233-P/233-1.5-P 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 PumpSaver
®
PumpSaver Plus will time through the restart delay, and then restart the pump. The calibration is
stored in permanent memory—it does not need to be recalibrated if power is lost.
CALIBRATION
NOTE: The Model 233-P/233-1.5-P should be
c alibrated during normal pumping conditions.
1. Turn the RESTART DELAY/ CALIBRATION knob
fully counter-clockwise to the CAL. position.
2. Apply power—the pump will run for approximately
10 seconds then shut off.
3. Set the RESTART DELAY/ CALIBRATION knob
to the desired restart delay (dry-well recovery
time)—the pump will turn on.
CALIBRATING WHILE PUMPING
The Model 233-P/233-1.5-P can also be calibrated while the pump is running. Turn the RESTART
DELAY/CALIBRATION knob to CAL. while pumping. Wait for the pump to turn off (approximately
10 seconds), then adjust the RESTART DELAY/CALIBRATION knob to the desired setting.
SENSITIVITY
®
The PumpSaver Plus 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
does not trip on dry-run or dead-head or it is known that the water level in the well is very low
r elative to the pumps capabilities.
WARNING: Decreasing the SENSITIVITY may compromise the PumpSaver
detect dry-run and/or dead-head conditions.
RESET MODE / RESTART DELAY
Any restart delay can be bypassed by rotating the RESTART DELAY/CALIBRATION knob to the
R ESET position and back to the desired restart delay setting.
NOTE: The restart delay can be changed at any time. The next trip will follow the new restart delay
s etting.
For test purposes, the RESTART DELAY/CALIBRATION knob can be placed in the RESET
position for manual reset. If the PumpSaver
problem, the RESTART DELAY/CALIBRATION knob must be rotated out of the RESET position to
r estart the pump.
