Troubleshooting (continued)
Variable Speed Drive Error Codes
In the case that an internal failure has been detected, the Variable Speed Drive will turn the motor off and display a
corresponding error code listed below. As well, the power LED will "FLASH" continuously. If more than one error has
been detected the screan will flash between the errors.
The Variable Speed Drive is protected against overload and overheating. If such an error occurs, the controller
will automaticly try to restart the motor six (6) times. After failing the sixth time to restart the display will show
the error message "Err20".
The cause of an error should be investigated and resolved before continuing normal operation of the pump. When the
issue has been resolved, press the RUN/STOP key to clear the error message.

Service Mode
When troubleshooting the pump or the pool system it may be useful to run the pump without other program functions
like default speed settings and timers. This can be achieved by setting the VSD into Service Mode.
To enter Service Mode remove the power from the pump. Hold down the DISP/FUNC button and then apply the power
to the pump. "tESt" will then be displayed on the screen before the motor RPM's while all three speed LED's will be
constantly flashing while the pump remains in Service Mode.
In this mode only the RPM of the motor can be changed between 600 rpm and 3000rpm and no speeds will be saved in
this mode.
To exit Service Mode simply cycle the power to the pump on and off.
