QD Pumptec and Pumptec
QD Pumptec and Pumptec are load sensing devices that monitor the load on submersible pumps/motors. If the load drops below a preset level for a minimum of 4 seconds the QD Pumptec or the Pumptec will shut off the motor.
The QD Pumptec is designed and calibrated expressly for use on Franklin Electric 230 V
The Pumptec is designed for use on Franklin Electric 2- and

| D. On Pumptec only check that Pumptec is installed between the control switch and | |
| the motor. | |
|
| |
| A. Be sure you have a Franklin motor. | |
| B. Check wiring connections. On Pumptec is lead power (230 V or 115 V) connected to | |
| correct terminal? Is motor lead connected to correct terminal? | |

| for information. | |
| E. On Pumptec applications does the control box have a run capacitor? If so, Pumptec | |
| will not trip. (Except for Franklin 1.5 hp motors). | |

| |
| A. Check for low voltage. | |
If your QD Pumptec or Pumptec chatters | B. Check for waterlogged tank. Rapid cycling for any reason can cause the QD Pumptec | |
