8.2. Troubleshooting with LEDs
When the controller is powered, the green LED will turn on. When powering down, the green LED will stay on until
the controller deenergizes. Please be patient, as it may take up to 60 seconds for the controller to deenergize.
When the controller has an error, the red LED will blink to indicate what errors and warnings have occurred. The
blinking indicates the error number. Error numbers are two digits long. Error codes are identified by the duration of
the pause; there are short, medium, and long pauses on the red blinking LED when an error occurs. A long pause
indicates the start of the error code, then short blinks will count out the first digit. A medium pause will indicate the
break between the first and second digit. The second digit will be counted out with subsequent short blinks. More
than one error can be indicated by the blinks. Note all errors until error codes repeat.
Some errors/warnings may require the pump to shut down, other errors are warnings of pump/controller
conditions that could cause problems in the future. Errors/warnings can be cleared using the PLC digital reset
input, or in the test serial interface by pressing the clear errors button. Errors will not clear if error condition is still
present.
