5.7.13Auto Cycle Fail

The status message “Auto Cycle n Fail” is displayed during a fail state. Once detected, the current cycle proceeds immediately to the Probe Insert step (if enabled) or to the Resume Delay step. The fail state remains for the duration of the Resume Delay, whereupon the fail state returns to zero and the fail message is cancelled.

A fail state also provides a detail message in the lower half of the Auto Cycle display regarding the specific reason for the error. These messages are listed in Section 12.4.

The digital output “AC n Fail” is also available and is active whenever an auto cycle failure has occurred. The auto cycle digital outputs: AC n Extract, AC n Rinse, AC n Cal Pt 1 and AC n Cal and AC n Cal 2 are available as relay digital input sources (See Table 6-4) to control the operation of valves and solenoids for exposure to rinse water and buffer solutions or air to accomplish the automatic probe rinse and calibration functions.
