Installation & Operation Manual
Problem
Pump runs without flow.
7.1 Errors and Alarms
If an alarm is triggered the drive's LCD screen will display the fault code text and the Variable Speed Pump will stop running.
Disconnect power to the pump and wait until the keypad LEDs have all turned off. At this point, reconnect power to the
pump. If the error has not cleared then proper troubleshooting will be required. Use the error description table below to begin
troubleshooting.
Fault Code
E-01
Inverter unit protection
E-02
Acceleration over current
E-03
Deceleration over current
E-04
Constant speed over current
E-05
Acceleration over voltage
E-06
Deceleration over voltage
E-07
Constant speed over voltage
E-08
Under voltage fault
E-09
Motor overload
E-16--Communication Link between the HMI and Motor control has been lost: Check the jacketed wire on the back side
of the keypad inside the drive top cover. Ensure that the 5 pin connector is properly plugged into the socket and that there is no
damage to the cable.
E-01,02,03,04,05,06,07,09,10,24--Internal Errors: If this error displays multiple times, then there may be a problem with
the pump's rotating assembly. Please disassemble the pump and investigate to see if there is a problem with the impeller or
mechanical seal. See page 13, '6.1 Shaft Seal Change Procedure' for instructions for disassembling the pump.
E-08--Absolute AC Under Voltage Detected: This indicates that the supply voltage has dropped below the operating range of
95v. This could be caused by normal voltage variation and will clear itself. Otherwise there could be excess voltage sag caused
by improper installation or improper supply voltage.
E-14-- Module overheating: Should be caused by high ambient temperature or overload.
Possible Cause
Impeller is loose.
Air leak.
Clogged or restricted plumbing.
Description
ENGLISH
Corrective Action
Check that pump is spinning by looking at fan on back
of Variable Speed Pump. If so, check
that pump impeller is correctly installed.
Check plumbing connections and verify they are tight.
Check for blockage in strainer or suction side piping.
Check for blockage in discharge piping including
partially closed valve or dirty pool filter.
