TROUBLESHOOTING
ALERTS AND WARNINGS
The Variable Speed Pump displays all alarms and warnings on the control panel display. When an alarm
or warning condition exists, the corresponding light will be lit on the display. All control panel buttons are
disabled until the alarm or warning is acknowledged with the Reset button. Pressing the Reset button will
clear the alarm once the fault condition has been resolved.
NOTE: The pump will not start if the impeller is rotating.
Power Out/OFF
The incoming supply voltage is less than 170 VAC. The drive faults to protect itself from over current. The
drive contains capacitors that keep it powered up long enough to save the current run parameters. If power
is restored during this process, approximately 20 seconds, the drive will not restart until completed.
Priming Failure
If the pump is not dened as primed within the “Max Priming Time” it will stop and generate a “Priming Alarm”
for 10 minutes, then attempt to prime again. The “Max Priming Time” is set by the user on the priming menu
as discussedon page 16. If the pump cannot prime within ve attempts it will generate a permanent alarm
that must be manually reset.
Overheat
If the drive temperature gets above 54.4° C (130° F) the pump will slowly reduce speed until the over
temperature condition clears.
Thermal Mode
When active, the motor will run at the preset RPM until the drive internal temperature increases above the
minimum. The pump’s internal thermal protection is disabled when connected to an automation system.
Thermal
protection is provided by selecting YES at the ON WITH FREEZE portion of the circuit function menu in
the automation control system. To re-enable the internal thermal protection, the power to the drive must be
cycled off then back on. Important: See explanation of Thermal Mode Over
Current
Indicated that the drive is overloaded or the motor has an electrical problem. The drive will restart 20
seconds after the over current condition clears.
Over Voltage
Indicates excessive supply voltage or an external water source is causing the pump and motor to rotate
thereby generating an excessive voltage on the drives internal DC buss. The drive will restart 20 seconds
after the over voltage condition clears.
Internal Error
Indicates that the self-monitoring motor control software has encountered an error. Clear the alarm and
restart the pump.
