11. TROUBLE SHOOTING
PUMP MODULE HAS STOPPED RUNNING
Pump system has faulted out due to loss in supply water pressure or VFD fault. Pump will try re-start in 30
seconds. If the water pressure has not been restored, or the VFD fault automatically re-set, the pump system will
remain off for another 30 seconds. After the second 30 second interval the pump system will again try to re-start.
If the water pressure has been restored or VFD was able to automatically re-set, the fault will clear and system will
return to normal operation. If the fault(s) has not been cleared, the pump system will lock-out and the LCD Display
will indicate the Fault.
INLET WATER PRESSURE FAULT:
Water supply to pump module may be inadequate. Check the following:
• Inlet water pressure has dropped below 20 P.S.I. (1.4 BAR)(correct water pressure)
• Dirty filter elements (inspect and replace if necessary)
• Water supply turned off (make sure it is on)
• Restriction in water line to pump (look for partially closed valve or other device)
• Other lines drawing water off line feeding pump module (the line should feed only the module).
