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 o ff. 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.

8.1
Errors and Alarms
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.

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 9 “Pump Disassembly” 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 200v. 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
