If the sampler detects an error that prevents it from taking a sample or continuing the program, it displays an error message.

There are messages for the following conditions:

Error Messages

ERRORS HAVE OCCURED

DURING PROGRAM

FATAL ERROR

NO DISTRIBUTOR ARM

• PUMP JAMMED	• NO LIQUID DETECTED
• DISTRIBUTOR JAMMED	• NO MORE LIQUID
• PROBABLE OVERFLOW	• PUMP LATCH OPEN
• POWER FAILED	• SAMPLER SHUT OFF
• LOW BATTERY	• BOTTLE FULL
• USER STOPPED	• SAMPLE IN PROGRESS
• NO DISTRIBUTOR ARM

Since the sampler may encounter more than one error during a program, it does not display the messages continuously. Instead, it records each error and the time it occurred in the Sampling Results and Combined Results report. It alerts you to the recorded errors by displaying the message, “ERRORS HAVE OCCURRED DURING PROGRAM.”

If the sampler detects a low battery condition, it stops the running program and displays the “LOW BATTERY” error message. A low battery condition exists when five consecutive sample events have resulted in a POWER FAILED error message.

Fatal Error – The Fatal Error message will only show up if you are using a multiple bottle configuration and the distributor system fails. Failing the test can indicate any of the following conditions:

•The distributor arm is not attached to the sampler.

•The distributor-arm stop inside the center section is missing or broken.

•The distributor drive mechanism inside the controller is malfunctioning.
