6000 Series Purge/Pressurization System
Do not use auxiliary contact for power to
enclosure(s).
Warning
If powering auxiliary equipment with
auxiliary 1 or auxiliary 2 outputs, the wiring
Warning
methods used must be suitable for the
hazardous area.
Temperature Inputs
The 6000-TEMP-01 temperature hub and 6000-TSEN-01
external temperature sensor(s) are designed to work only
with the 6000 purge and pressurization system.
An averaging or maximum temperature input reading
from the sensor(s) is used to control a solenoid valve or
activate the auxiliary relay to cool or heat the enclosure,
or warn of temperature problems.
In the programming menu, under "SENSOR SETUP",
"EXT SENSOR COUNT", you can configure up to 3
sensors per temperature hub. Each temperature hub has
one embedded temperature sensor. In the programming
menu under "INPUT SETTINGS" you will select the
"HUB". This must be selected if you want to include the
hub as a sensor input.
You may not want to include the temperature as
an input if the sensor is not located near the
device or process you are tracking the
Note
temperature of.
Once a "CONTROL ACTION" is selected, then select
"SETPOINT TYPE" for the "AVERAGE" or "SINGLE PT".
If using more than one (1) sensor, you may want
the control action to occur during the peak or
Note
average temperature of the sensors.
"ON SET POINT" and "OFF SET POINT" are the
temperatures for the control action.
The "ON SET POINT" can be greater than the
"OFF SET POINT"

EPV-6000 I.S. relief vent
The EPV-6000 vent exhausts excess pressure from the
enclosure when the enclosure pressure exceeds the
breaking pressure of the vents relief mechanism. This
pressure and flow is measured during operation. The
6000 series vent has a pressure transducer and thermal
flow sensor that is connected to the 6000 EPCU and is
intrinsically safe through the galvanic isolation barrier
within the EPCU. The measurement of the flow is always
at the exhaust of the pressurized enclosure; therefore,
the vent is located on the enclosure(s) such that it is
venting to the atmosphere.
When using the complete 6000 series system, the
vent is connected to the I.S. termination board using
the M12 (V1) connector and cable that come with the
vent. If using the 6000 series component kit, the vent is
connected to the EPCU as shown in the diagram on page
19 (brown wire to terminal 2, blue wire to terminal 4,
black wire to terminal 10, white wire to terminal 11). The
EPV-6000 vent can be mounted vertically or horizontally
and is not gravity dependent. For corrosive environments,
the EPV-6000 vent can be ordered with a stainless steel
cap so that the body of the vent can be mounted in the
enclosure with only the stainless steel cap exposed to the
outside environment.
LEDs for the vent
LED indication for the vent is green for power and amber
for second address vent which is used in two-vent / one-
EPCU systems.
