Model 9200 Programmable Dual-loop Controller

Alarm Ack

The “Alarm Ack” button displays the “Active Alarm” screen. From which you can acknowledges any alarms that have been configured, or that have been made part of the recipes that run on the Series 9200. If a recipe has an alarm as a step, the alarm must be acknowledged before the recipe will continue to the next step.

Data Logging using Flash Card

SEE THE WARNING !!! Section of the Manual before removing flashcard)

The Advantech TPC-642S/642-SE touch screen operator interface utilizing a Compact Flash card allows the unit to data log the parameters setup by a qualified SSi technician. Should a customer not take his data offline in a timely manner, the data will be over-written, the oldest data being that which is over-written first. Here is how it works:

1.When the ADVANTECH operator interface detects that there is less than 5% disk space left on the Compact Flash card, an alarm will be displayed on the main interface screen stating "x% disk space remaining (overwrite at 3%)". In the upper right corner, an ALM is indicated, but because it is not a communications alarm or a 9200 device alarm, the background remains green. This alarm will remain active until more than 5% of disk space is available for writing data log files.

2.If the user does not copy the log data from the disk, it will eventually fall to 2% disk space. At this point, the touch screen will select the oldest compressed file and delete it. It then checks to see if 3% remains. It repeats this procedure until 3% disk space remains. At this point the alarm message changes to "Overwriting data log data!” Because this allows the system to seesaw between 2% and 3%, it will continue to display "Overwriting data log data!" until somebody offloads the files.

Technical concerns and details:

1.If there are not enough compressed files to bring the free space up to 3%, the system will hunt down and kill hourly files. This should only happen if compression would not be running for some reason.

2.If all compressed files and hourly files have been removed and there is still not enough disk space (perhaps a problem with the Compact Flash card), the data logger will not write to the disk until the condition is remedied. (Alarms continues to display)

3.The data log data alarm is the lowest priority. The alarm priorities are touch screen communications, then 9200 controller/programmer, then disk space.

!NOTE: See “Warnings” with respect to removing the “flash card”.
