| Series Features |
| 233P Series - Single-Phase Pump Monitor |
| Series Description: The Littelfuse models 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) are single- phase pump monitors used in a variety of applications to protect from dry-well, dead-head, jammed impeller, rapid-cycling, overvoltage, and undervoltage conditions. |
| Series Operation: A calibration adjustment allows the unit to be calibrated to your specific pumping applications, which reduces the possibility of false or nuisance tripping. A unique microcontroller-based voltage and current-sensing circuit constantly monitor the incoming power for fluctuations, overcurrent, and undercurrent conditions. When an abnormality, such as loss of suction, is detected, the product deactivates its output relay and directly disconnects the pump motor. The relay then begins its user-selectable restart delay (dry-well recovery) timer. When the timer counts to zero or power is removed and reapplied, the relay reactivates its output relay and turns the pump back on. The infrared LED communicates with a hand-held diagnostics tool called the Informer* (sold separately). The Informer displays parameters including calibration points, trip points, run time and last faults. There are 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 relays terminal size. In these conditions, a short splice of #10 AWG or #12 AWG may be a solution at the control box. Note: All local, state, and national electric codes should be followed when applying this solution. |
