The following paragraphs describe the parameters that you may view and/or
change.
8.6.1 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.
8.6.2 Alarm Setpoints
This option allows the operator to choose an analog or exit the window. When the operator
chooses an analog, a window will be displayed to allow the operator to enter a new user analog
setpoint value. The User Analog Setpoints window will display 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 ten setpoints will exist per analog input. The number of user
setpoints will be equal to ten minus the number of VERSUM MATERIALS, INC. 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 Process Cyl.
Very Low Process Cyl
Regulator Creeping (may also serve as a high pressure delivery alarm)
Low Process Del.
Low Cyl. Weight
Very Low Cyl. Weight
