Unique Features of the nextec Pump
Your nextec fuel transfer pump will perform differently from non-intelligent pumps on start-up and while operating. You will want to keep the following in mind as you
begin to use and learn how your nextec Intelligence™ pump operates.
•
On initial start up, the pump may rev momentarily, but will slow down, as if idling, as it reponds to the load it senses. This is a normal condition, and it will
continue at this low speed until you squeeze the handle on the dispensing nozzle to begin fluid flow.
•
When you squeeze the nozzle handle to begin flow, the microprocessor in the pump will sense the change, and will raise the RPM's to meet the load.
It is not uncommon for the pump to change RPM's during operation. It will do this as it senses performance parameters are changing; for example, if you increase or
decrease the flow at the nozzle, the electronics controlling the motor will sense the changes and adjust the motor speed to optimize performance.
•
If the pump senses a condition that is outside normal operating parameters (low battery voltage, for example), it will sound a series of tones to alert you to the
condition, and to help you diagnose it. See the "Intelligent Tones" section of the Troubleshooting Guide on page 15 for greater detail on this feature.
•
Your NX25-DDC pump has a Continuous Duty Cycle, meaning it does not have to be shut off to "rest" after a specific period of use. This allows you to move
from fueling one piece of equipment to another without having to shut the pump off. The nextec Intelligence does, however, have an automatic shut off if the
pump is left running in bypass mode (without dispensing any fluid) for 20 minutes. This features protects from excessive battery drain, as well as excessive
uneccessary wear to the pump in the event you forget to shut the pump off. Should the pump turn itself off under these conditions, simply cycle the power
switch off, then back on to restore pump operation.
•
The nextec Intelligence will also shut the motor down if:
►
Pump temperature exceeds threshold parameters
►
Supply voltage is outside threshold parameters
►
Rotor is locked

Safety Information
DANGER
Electrical wiring should be performed with extreme caution and in compliance with local, state, and national electrical code NEC/ANSI/NFPA 70,
NFPA 30, and NFPA 30A, as appropriate for the intended use of the pump. Threaded rigid conduit, sealed fittings, and conductor seal should be
used where applicable. The pump must be properly grounded. If installing in deviation of this manual, a licensed electrician must perform the
installation. Improper installation or use of this product will result in serious bodily injury or death!
DANGER
To ensure safe and proper operation of your equipment, it is critical to read and adhere to all of the following safety warnings and precautions.
Failure to follow instructions below, improper installation, or use of this product, will cause serious bodily injury or death!
DANGER
To minimize static electricity build up and possible explosion, use only static wire conductive hose when pumping flammable fluids, and keep
the fill nozzle in contact with the container being filled during the filling process. Spark / static discharge will cause explosions.
WARNING
Threaded pipe joints and connections should be sealed with the appropriate sealant or sealant tape to minimize the possibility of leaks. Leaking
fuel may cause the potential for fire and explosion.
