RUN HOURS
The Model 233-P records pump run hours. Run hours can be displayed by a PumpSaver
®
Plus
Informer (see USING AN INFORMER on the following page). Run hours can be reset on the 233-P.
Read the following instructions fully before performing the procedure.
NOTE: Turn the SENSITIVITY knob completely to the left (counter-clockwise) or completely
to the right (clockwise) when directed.
To Reset Run Hours:
1. Remove power to the 233-P.
2. Set the RESTART DELAY/CALIBRATION knob to RESET and the SENSITIVITY knob to the
middle (12:00) position.
3. Apply power to the 233-P—the CAL. LIGHT will turn on.
4. Turn the SENSITIVITY knob to the right—the CAL. LIGHT will turn off and the RUN LIGHT will
turn on.
5. Turn the SENSITIVITY knob to the left—both lights will turn on.
6. Turn the SENSITIVITY knob to the right.
7. After 10 seconds, the CAL. and RUN LIGHTS will blink twice indicating the run hours have
successfully been reset.
RAPID CYCLING
Rapid cycling is defined as more than 4 restarts in a 60-second period. The Model 233-P is capable
of detecting a rapid-cycle condition whether a control device, such as a pressure switch, is installed
before or after the 233-P. Upon detecting either form of rapid cycling, the 233-P will lock-out until
power is removed and re-applied.
Protection against rapid cycling of a pressure switch installed before the Model 233-P can be
disabled. Read the following instructions fully before performing the procedure.
NOTE: Turn the SENSITIVITY knob completely to the left (counter-clockwise) or completely
to the right (clockwise) when directed.
To Disable Rapid-Cycle Protection when a Pressure Switch is Installed BEFORE the 233-P:
(to re-enable, follow the same procedure)
1. Remove power to the 233-P.
2. Set the RESTART DELAY/CALIBRATION knob to RESET and the SENSITIVITY knob to the
middle (12:00) position.
3. Apply power to the 233-P—the CAL. LIGHT will turn on.
4. Turn the SENSITIVITY knob to the right—the CAL. LIGHT will turn off, RUN LIGHT will turn on.
5. Turn the SENSITIVITY knob to the left—both lights will turn on.
6. Turn the SENSITIVITY knob right—left—right—left—right.
7. After 10 seconds, the CAL. and RUN LIGHTS will blink twice.
USING AN INFORMER
The Model 233-P is equipped with an infrared LED that will communicate to a SymCom Informer—
a handheld, battery-operated, diagnostic tool. The Informer—when directed at the Model 233-P—
will display real-time voltage, current and power; dry-well and overload trip points; calibration
voltage; last 20 faults; voltage, current and power at the last fault; highest/lowest voltage and
current since calibration; the model number; and the CT size if applicable. The Informer can be
used on any single-phase PumpSaver® equipped with an infrared LED transmitter—Models 111-
and 231-Insiders; 231-P Insider; 112- and 232-Insiders; 111; 233-1.5(-P); 233(-P); 234; and 235.
