6000 Series Purge/Pressurization System
Operation of the 6000 series and component
kit
Operation
The 6000 series consists of the control unit and user
interface mounted in a 316L (UNS S31603) stainless
steel Type 4X (IP66) enclosure with the pneumatic
solenoid valve mounted on the unit. The EPV-6000 series
relief vent is separate and is mounted to the enclosure.
The 6000 series control unit is also available as a kit. The
kit consists of the key components of the system, the
control unit, and the user interface. It does not include
the enclosure. The manifold is an optional item. The
user interface includes a panel-mount bracket so that it
can be panel mounted to the customer's enclosure. The
pneumatic valve for the protective gas can be supplied by
the customer. The EPV-6000 relief vent is still required.
The components of the 6000 series control unit, with
'-WH-' housing, are listed below:
• EPCU mounted in an explosion-proof/flameproof
enclosure
• I.S. user interface with display and cable
• I.S. termination board (not included with "CK" kit
version)
• Manifold with I.S. solenoid valve (not included with
"CK" kit version)
• Flush mount Type 4X IP66 fitting for protective gas
supply to enclosure with tube attached
• Type 4X cable glands for I.S. wiring to I.S. inputs,
vents, and temperature modules
• 3/4" pipe nipples for power wires
• 316L (UNS S31603) stainless steel Type 4X
enclosure for the 6000 series controller. (Not
included with the component kit.)
The components of the EPV-6000 vent:
• EPV-6000 vent with stainless steel spark arrestor
screen
• 1½" lock nut with grounding lug and gasket for
attachment of vent to customer's enclosure
• One 5 m (16.4 ft.) quick disconnect cable; for
connection to I.S. termination board inside 6000
series control unit.
If ordering a stainless steel vent, an atmospheric
reference kit is included for internal mount.
Note
The components of the 6000 series component kit are
listed below:
• Control unit and explosion-proof/flameproof
enclosure
• 6000-UIC-01 user interface
• SMK-600-CK mounting hardware for 6000-UIC-01
• One 5 m (16.5 ft.) quick disconnect cable for 6000-
UIC-01
• 6000-MAN-DV-01 pneumatic manifold w/ solenoid
(optional)
• EFC-6-SS flush mount connector
The 6000 series control unit and vent can be universally
mounted to the customer's enclosure. Top, bottom, right-,
or left-side mounting can be completed with only one
control unit and vent. Mounting configuration does not
need to be designated when ordering. One unit is used
for enclosure sizes up to 450 ft
Optional accessories are available to make the
component kit easier to install. The 6000-ISB-01 I.S.
DIN-mounted termination board and 6000-CBLA-ISB-xxx
cable harness allow easy connection to the EPCU of the
control unit.
Electronic power control unit – EPCU
The EPCU houses the redundant microprocessors,
enclosure power contacts, (2) auxiliary contacts, power
supply module, galvanically isolated barriers for the
inputs, vent(s), and temperature modules. The EPCU
is easy to remove and install into the explosion-proof
enclosure that houses it.
The EPCU is available in 20 ... 30 VDC or
100 ... 250 VAC units. The enclosure power contacts are
force-guided safety relays. The auxiliary contacts can be
user configured for different functions, depending on user
requirements.
User interface controller – UIC
The 6000 series is user programmable for many of the
configurable options available. This is done with the
intrinsically safe user interface on the face of the unit,
which can also be remote mounted. The user interface
contains a 2 x 20 LCD that allows programming through
a set of buttons on the menu-driven unit. All configuration
and options are programmed through this unit. There are
also (5) LEDs for easy visual indication of operation:
• Safe pressure – This turns on (blue) when safe
pressure is achieved inside the enclosure.
