OPERATION
The Model 233-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 233-P—after the trip delay—will turn off the pump. The 233-P 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 should be calibrated
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 15 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 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 Model 233-P 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.
MANUAL RESET MODE / RESTART DELAY
Set the RESTART DELAY/CALIBRATION knob to RESET for manual reset mode. If the 233-P
trips off due to a voltage or load problem, the RESTART DELAY/CALIBRATION knob must be
rotated out of the RESET position to restart the pump.
NOTE: Any restart delay can be bypassed by rotating the RESTART DELAY/CALIBRATION knob
to the RESET 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
setting.
