This sequence does not remove hazardous
gases to a low enough concentration to permit
operator maintenance or other activity on the
process line or downstream components. The
customer must develop purge and evacuation
procedures for the process line and components
downstream of the Distribution System to
assure acceptable low concentrations of
hazardous gas to permit maintenance of this
equipment.
NOTE: Either the Flow Purge or the Rough Line Evacuation sequence
will be installed in the AP10 controller per the original order. See the
System Specific Information provided with the equipment to determine
which process line purging sequence is installed for this system.
7.6
Configuration Menu
The configuration menu contains a collection of files that are used to define the
operation of the AP10 controller. The files establish operating sequences for valves
during various operating modes, define digital alarm responses, and establish setpoints
for analog devices.
Access to the Configuration Menu requires a second or higher level password. Access to
individual files in the menu is further restricted by password security level based on the
content of the files. Many of the files are only accessible by VERSUM MATERIALS,
INC. personnel with 4th level security. This is to prevent changes to the operation of the
system that may cause unsafe conditions.
See Section 8.8 for more details of the configuration menu and descriptions of the files
that the customer may access for changing parameters such as non-critical setpoints or
number of purge cycles, or for viewing only.
