Troubleshooting
DANGER
Disconnect all power prior to performing any service or maintenance. Failure to disconnect the power may cause electrical shock, or unexpected
starting of the motor, resulting in injury or death.
DANGER
DO NOT open or attempt to repair the motor on your Fill-Rite pump. Return it to the place of purchase for service. Opening the motor case will
compromise the integrity of the Explosion Proof construction and void any existing warranty, approvals, and certifications (i.e.: ATEX, UL listing, CE, etc.).
This Troubleshooting guide provides basic diagnostic assistance. If you have further questions, contact us at 1 (800) 720-5192 or via email at FillRiteTech@fillrite.com
(M-F, 8 AM – 5 PM ET).
Intelligent Tones
Your NX25-DDC pump features a self-diagnostic system that will aid you in troubleshooting should the need arise. The pump will give off a series of high and low
tones; simply count the high and low tones to determine which conditions exist.
Depending on the condition the pump senses, it will generate either a 3-tone code, or a 4-tone code:
•
3-Tone codes indicate an application fault; something dealing with the installation of the pump, like a priming or supply voltage concern.
•
4-Tone codes indicate a pump fault; a condition outside the operating parameters of the pump, like an over- temperature condition, or something dealing with
the pumps internal electronics.
Refer to the table below to determine which condition your pump is detecting, and how to resolve it. In the chart below, arrows pointing up (↑) indicate high tones,
arrows pointing down (↓) indicate low tones; their order tells which fault is detected. Conditions listed in BOLD are not field servicable, and require the pump to be
returned to the manufacturer.
3-Tone Faults (Application / Installation faults)
Tones Condition
↑ ↓ ↓
Low battery voltage (auto shut-off)
↑ ↓ ↑
High battery voltage (auto-shut off)
↓ ↑ ↑
Locked rotor (auto shut-off)
↓ ↑ ↓
Priming / Suction / Lift failure
4-Tone Faults (Hardware faults)
Tones Condition
↓ ↑ ↑ ↑ Hardware fault (auto shut-off)
↓ ↑ ↓ ↓
Hardware overtemperature (auto-shut off)
↓ ↓ ↑ ↑
Motor overtemperature (auto shut-off)
↓ ↓ ↑ ↓
Motor overvoltage (auto shut-off)
↓ ↓ ↓ ↑
Motor undervoltage (auto shut-off)
*This condition will shut the motor off. To restart the motor, cycle the switch off, then back on.
** Prior to returning pump to place of purchase, perform this procedure: cycle the switch off and disconnect power for at least one minute. Reconnect power,
and cycle the switch back on. Verify proper pump operation. If this procedure does not restart the pump, or if you have additional questions, contact Technical
Support at 1 (800) 720-5192.
