Purge Operating Modes
On the Reports screen, touch PPuurrggee OOppeerraattiinngg MMooddeess to view the current operating status of
the purge system in terms of the top-level operating mode and submodes.
NNoottee:: For Duplex™ chillers, the operating status of purge system is shown in terms of the two
circuits.
The purge system operates in one of four top-level operating modes:
• Stop
• On
• Auto
• Adaptive
Submodes are dependent on the top-level mode. Their appearance on the Purge Operating
Modes screen has the following characteristics:
• The newest submode appears at the top of the submode list.
• Submodes disappear when they no longer apply.
• The screen displays up to six submodes.
• If less than six submodes are active, the submode rows that do not apply are blank.
For detailed information about purge operating modes and submodes, refer to PRGF-SVX001*-
EN (Installation, Operation, and Maintenance: EarthWise Purge System with Tracer AdaptiView
Control for Water-cooled CenTraVac Chillers with R-123 Refrigerant) or PRGG-SVX001*-EN
(Installation, Operation, and Maintenance: Purge System with Tracer AdaptiView Control for
Water-cooled CenTraVac Chillers with R-514A Refrigerant), as appropriate.
