In the last issue of Franklin Aid we spoke on only breaking one wire with a control switch. Since then we have received calls that felt not enough emphasis was placed on the shock hazard potential involved with only breaking one wire. Franklin’s primary concern with all information is the safety of the men and women of our industry. Please be careful.
New and Improved PUMPTEC: As part of our efforts to continually improve submersible motor products, Franklin Electric has made several enhancements to the PUMPTEC Pump Protection System.
Diagnostic Indicator Lights: The most noticeable change is the addition of two lights: a green “POWER ON” light and a red “TRIPPED” light. The “POWER ON” light illuminates whenever power is applied to the PUMPTEC. Since PUMPTEC installs after the pressure switch or control switch, this normally means the pump/motor is running. If PUMPTEC detects an underload condition such as occurs with a dry well or broken shaft, it disconnects power to the motor and illuminates the “TRIPPED” light. Once the adjustable recovery or delay time elapses, PUMPTEC reapplies power to the motor and turns off the “TRIPPED” light. Auto-reset recovery time is still adjustable from 2 to 90 minutes or PUMPTEC can be set for manual reset only.
Signal or Alarm Contact: Closely related to the new “TRIPPED” light is a new signal circuit which can be used to turn on an external indicator. This is done through a terminal labeled “SIG” or “SIGNAL”. A signaling device (1 amp maximum) such as a light, relay or bell can be connected between this new terminal and the voltage terminal in use (115 or 230). Note: The signal device must be rated for the same voltage as the incoming power supply used for the PUMPTEC unit. If the PUMPTEC trips, the signal circuit closes and turns on your external device. In this way the signal contact and the “TRIPPED” light operate together. Once the recovery or delay time passes, the PUMPTEC resets and turns off your signaling device. One important thing to note is the signal circuit is energized for a few milliseconds every time the pump runs. This could cause a bell or buzzer to emit a slight noise or cause a light to flicker when the pump starts.
Higher-rated Contactor: The contactor used to break power to the motor when PUMPTEC trips has changed from an open-frame type to an enclosed type. Although it looks smaller than the old open-frame contactor, the new contactor is actually higher rated. This same contactor has been successfully used in Franklin Electric’s QD PUMPTEC for over two years.
Improved Rotary Switch: A minor change has been made in the rotary switch used to set the amount of time that PUMPTEC remains in the “tripped” condition before resetting (recovery time). This switch now has an arrow, giving the installer a more definite indication of where the switch is set. Just as a reminder, PUMPTEC is still factory-set for a 30 minute recovery time.
It is important to note the PUMPTEC works the same as it always did. The new model number is 580 002 0116. This is a change in the last two digits of the previous number from “00” to “16”. For brochures or more information, please contact your pump supplier or Franklin Electric representative.
Why doesn’t my Pumptec seem to restart after the recovery time has passed?
This is a common question we receive on Franklin’s Service Hotline. One of the main reasons that prompts this phone call is the Pumptec has already timed-out, tried to restart the motor, found insufficient water, and retripped. You also need to check to see if the timer adjustment switch is set in the manual restart or “0” position. This position requires that power to the Pumptec be turned off for 5 seconds before the Pumptec will reset. Another possible cause for the Pumptec not to reset is that the timer adjustment switch is located between indents or notches. This rotary switch is not an infinitely adjustable device. It has specific notches or locations that have to engage.
So, whenever you receive a call “My Pumptec won’t reset.”, make sure the recovery time adjustment knob is not between marks or notches, the switch setting is not in the manual restart position, and there is water in the well.
