Super Systems 9200 - Manual (Page 14)

Model 9200 Programmable Dual-loop Controller
SSi Manual SERIES 9200 14 Programmable Dual-loop
Pressing the Note key displays an alphanumeric keypad asking for operator ID or initials. Pressing the
appropriate keys and then pressing the <- Enter key displays another alphanumeric keypad and prompts
the operator to enter a note. After pressing the keys on this keypad and then <- Enter key, the next
screen displayed asks you where you want the note written. The default choice is the current time and
date. You can change the parameters and place the note at whatever time and date is required. Pressing
the OK key takes you back to the real time chart page.
Pressing the Realtime key brings the chart display back to the current time.
The View key allows you to look at the NOTES that have been stored with the chart.
Alarm Ack
The Alarm Ack button displays the Active Alarm Screen. From which you can acknowledge 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
NOTE: See Warnings with respect to removing the Flash Card.
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 continue 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.
