Diagnostic Fault Codes
The system continuously monitors system performance and can detect a variety of abnormal conditions.
In many cases, the controller will compensate as needed to maintain continuous system operation. But, if
there is high risk of equipment damage, the controller will protect the system by shutting itself down. To
help identify that there is a problem with the system (including incoming water and electricity from the util-
ity company), the system will display that there is a fault condition.
Refer to "Status Display" on page
Count the repetitive flashes to determine which fault the unit is reporting.

Water logged tank
8 Flashes Temperature
No check valve installed in system plumbing.
Leaking or blocked check valve
RAPID Internal Fault A fault was found internal to drive
Symptom Based Troubleshooting
Leaky Systems
Leaky water systems might keep the controller running due to the accurate pressure sensing capability of
the pressure sensor. Continuous running or starts and stops do not hurt the controller, pump or motor. How-
ever, to reduce the on-time of the controller/pump/motor, a "Bump-Mode" feature is installed.
During low flow (or leaky) conditions, this feature periodically increases the speed of the pump several psi
above the set point and shuts off the pump. This adds some time to bleed off before the system starts up
again.

Possible Cause Corrective Action
The pump is running dry. Check water source.
Restrict pump discharge to prevent cavitation.
Raise minimum water level in cistern.
Line voltage is low, less than approximately 190 VAC
Check incoming power connections. Correct or tighten
if necessary.
Check pump for external damage.
Flush debris from pump and add input screen.
Wires to motor are open circuit. Check motor connec-
tion.
Check motor connections.
Ambient temperature has exceeded 104 °F (40 °C).
Shield from direct sunlight.
Ensure air temperature around drive does not exceed
104 °F (40 °C)
Remove debris from heat sink fins.
Restore water supply to the unit. Refer to
Tank Pre-charge" on page 5.
Close bypass plumbing loop.
Check tank precharge. Correct tank air pressure or
replace pressure tank as required.
Install a check valve. Refer to
page 7.
Replace check valve.
Contact a professional service provider.
