Fixed Analog Setpoints (VERSUM MATERIALS, INC. Setpoints)
The Fixed Setpoints window will display all analogs used in the system. The operator will be allowed
to choose an analog from the drop down menu or exit the window. When the operator chooses an
analog, the corresponding setpoints for that analog will be displayed. The Fixed Setpoints window
will display the Versum Materials-defined analog alarm data. The window will display the alarm
number, alarm label, and current alarm setpoint for each Versum Materials alarm. A total of 30
setpoints will exist per analog input. The number of Versum Materials fixed setpoints will be equal to
30 minus the number of user 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. The Fixed Setpoints
window will only be accessible with an Versum Materials-level password.
Alarm Conditions
The Alarm Conditions window will display the alarm input type, alarm number, alarm label, and alarm
condition for each system alarm. This window will allow the operator to change the alarm condition
for digital alarms to either a closed, open, or not used. The alarm condition for analog alarms is either a
high, low, or not used. The window will allow the operator to change one or more alarms or to exit the
window without changes
Alarm Delays
The Alarm Delays window will display the alarm input type, alarm number, alarm label, and current
alarm time delay (in seconds) for each alarm in the system. The window will allow the operator to
enter a new time delay value for one or more alarms or exit the window. A delay entry of ‘0’ equates
to no delay. The range of values is from 0 to 255 seconds.
Alarm Types
The Alarm Types window will display the alarm input, alarm number, alarm label, and alarm type for
each alarm in the system. The possible alarm types are Fault, Shutdown, Sequence Controlled, and
Non-Latching. The window will allow the operator to exit the window or change the alarm type of one
or more alarms. An alarm having an alarm type of Sequence Controlled cannot be changed to a
different type. All other alarm types can be changed; however, the alarm type cannot be changed to
Sequence Controlled.
Alarm Sequences
The Alarm Sequences window will display the alarm number and alarm label for each alarm in the
system. The window will also display the alarm response sequence and alarm response sequence label
for those alarms that have an alarm response associated with them. The window will allow the
operator to exit the window or select one or more alarms to view the alarm response sequence.
Changes to alarm response sequences will not be allowed.
