7.7
Manual Mode Operation
The Manual Mode file in the Configuration Menu permits authorized personnel to open
and close any pneumatic control valves individually. Manual Mode provides a means of
flowing purge gas, weld shield gas and certification gas during system installation and
start-up procedures. It also provides a means of flowing purge gas while maintenance or
repairs are being performed.
Access to Manual Mode operation is restricted to 2nd or higher level supervisory personnel.
See Section 8.6 for detailed instructions for Manual Mode operation.
Only experienced operators should operate the
Distribution System in Manual Mode.
Operating valves out of their proper sequence
could potentially cause damage to the product
by interrupting or providing insufficient gas
flow. Manual operation should not be used for
process gas flow as critical shutdown alarms
may be disabled in Manual Mode.
