Model 9200 Programmable Dual-loop Controller
SSi Manual SERIES 9200 21 Programmable Dual-loop
to change the minutes press the “min” key. The next screen that pops up in both cases is a numeric
keypad. Enter the number of minutes that you wish to permanently change the recipe to and press the
“Enter” key. If you DO NOT wish to make any changes press the “Esc” key. Note, if you wish to only
change the minutes, you must enter the desired hour(s), if other than 0.
If you have made a change, pressing the “Enter” key takes you back to the “Time Edit” screen. If you wish
to make the change, press the “set” key on the right-hand side of the screen. The next screen to pop up
verifies the time has been changed to the number of minutes that you have selected. Pressing the “cancel”
key takes you back to the full program screen. If you are sure that you want the change to be permanent
press the “set” key. This takes you back to the screen that shows you the entire program. Notice that the
time has been changed on the program segment that you were editing. If you wish to save this change
press the “save” key. You will notice that a numeric keypad pops up and asks you to enter the number of
the program that you wish to save. “Enter” You must enter the desired program number you wish to save
these changes to.
NOTE: See the APPENDIX section of this manual for a sample program.
The “Esc” button takes you back to the “default” menu.
CO Factor Entry
Pressing the “login key” takes you to the “enter password” screen. Entering the correct password (the
default password is “2”) displays the “default” menu which includes:
Highlighting the “CO Factor Entry” and pressing “Enter” pops up the “Factor Entry” screen, showing the
parameter as CO Factor and Value as is currently in the Series 9200. To make an adjustment press the
“Enter” key. A numeric keypad will be displayed. Using the keypad enter the number that you wish the CO
Factor to be and press the “Enter” key. This returns you to the original “Factor Entry” screen, which now
shows the new CO Factor that you have entered. If you do not wish to make the change simply press the
“Esc” key which takes you back to the “Factor Entry” screen with NO change being made to the CO Factor.
The COF factor allows you to make adjustments that will allow the controller to match the results obtained
when measuring shim stock. If the controller set point and the process variable are the same, but you are
not attaining the desired surface carbon, you can make the adjustment with the COF Factor to increase the
amount of surface carbon available to the parts. If you lower the COF factor, it immediately lowers the %
Carbon process variable. This will cause the controller to add more enriching gas--- raising the process
variable until once again the process variable and the set point match. Conversely, raising the COF Factor
will cause the process variable to read higher, shutting down the enriching gas solenoid (possibly turning
on the air dilution solenoid) causing the % Carbon process variable to begin to lower (NOT ADDING
ENRICHING GAS) until the set point and process variable match.
Pressing the “Esc” button takes you back to the “Menu Screen”
