2.2 The 6500 system
The 6500 purge/pressurization system consists of the following devices:
6500 control unit: The control unit provides all the functions
including user-defined functions. The 6500 controls the actions
for the system and supplies the supporting devices.
EPV-6500 vent: The EPV-6500 vent provides pressure
relief to the pressurized enclosure and feedback to the
6500 control unit with pressure and flow information. The
EPV-6500 vent is intrinsically safe with I.S. power and signal
protection from the 6500 control unit. There are two families
of vents that are selected at the time of ordering and can
provide standard application parameters or are specific to
dilution applications.
6500 MAN-DV manifold system (optional): The 6500-
MAN manifold has a digital valve that is activated by the 6500
control system for purging and cooling and pressure control.
It is intrinsically safe and has a needle valve for adjusting the
pressure in the enclosure after purging or pressurization.
