AP11 controller files may be modified using a second or third level security
code. These modifications are referred to as the source system configuration.
The source system configuration may be accessed from the CONFIGURATION MENU option on the
Main Menu. From the CONFIGURATION MENU, you may display some configurable parameters
and change user configurable parameters.
For safety considerations, most configuration parameters may be changed only by Versum Materials,
Inc. technical personnel.
The following paragraphs describe the parameters that you may view and/or change.
Net Product
This option allows the operator to display either a gross or net value on any analog. The gross value
will display the normal analog reading with no adjustment. The net value will display a “net” reading
based on the value input by the operator. If a value other than zero is entered in this window, the “net”
value will be calculated and displayed for this analog. A “net” tag will also appear at the analog
display box. If zero is entered, the gross or unadjusted value will display with no additional tag.
This window is also used to enter the full cylinder pressure of the process and purge cylinders installed
in the system. The analogs configured for displaying cylinder pressures will prompt for the “max cyl
press” instead of a “net product”. This will not occur however if a process cylinder scale is utilized, in
which case the process cylinder analogs will function as standard analogs.
User Analog Setpoints (User Setpoints)
This option allows the operator to choose an analog input device from a drop-down menu or exit the
window. When the operator chooses an analog input device, the corresponding setpoints will be
displayed. The operator has the ability to select and change any of the setpoints. The User Analog
Setpoints window displays the customer/user defined analog alarm data. The window will display the
alarm number, alarm label, and current alarm setpoint for each user defined alarm. A total of 30
setpoints will exist per analog input. The number of user setpoints will be equal to 30 minus the
number of Versum setpoints. This window will allow the operator to enter a new setpoint value for
one or more chosen alarms or exit the window without changes. These setpoints may include one or
more of the following:
Low Low Process Cyl Pressure
Low Process Del. Pressure
Low Cyl Weight
Low Low Cyl Weight
