Intelligent Tones - Tuthill Fill-Rite nextec Intelligence NX25-120 Serie Manuel D'installation Et D'utilisation

Intelligent Tones

Your nextec pump features a self‑diagnostic system that will aid you in troubleshooting should the need arise. The pump will emit a series of tones; note the order and number
of high and low pitched tones to determine the fault condition.
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. Conditions listed in BOLD are not field serviceable, and require the pump to be returned to the manufacturer.
3-Tone Faults (Application / Installation faults)
Tones Condition
↑ ↓ ↓ Low input voltage (auto shut‑off)
↑ ↓ ↑ High input 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, or cycle power to motor.
** 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 Customer Service at 1-800-634-2695.
