Connecting the Test Station Ports
The ports and connections on the rear of the ARES-G2 are used to connect various components of the sys-
tem to the instrument. This section describes these ports. All instructions are based on viewing the instru-
ment from the rear. Refer to the figure below as you make the connections.
CAUTION: Make sure there is no power going to the power supply unit while making the connec-
tions described here. Turn the power switch to the off position.
MISE EN GARDE: Assurez-vous que le bloc d'alimentation électrique n'est pas alimenté en courant
pendant le réglage des connexions décrites ici. Placez l'interrupteur d'alimentation sur la position
d'arrêt.

Gas ports on rear of ARES-G2
•
Oven Purge
: Provides dry gas input to the oven. The gas is circulated throughout the oven in order to
maintain positive pressure and minimize frost when using the LN
2
cooler.
•
Air Inlet
: Connects to the (external) air dryer. This port is used to supply dry air to the oven, motor,
transducer air bearings, and throughout the test station. The air supply pressure should be 80 to 90 psi
(0.55 to 0.6 MPa).
•
Gas Inlet
: Connects to an external nitrogen (or other) inert gas supply. This port supplies nitrogen or
another inert gas to the oven, thus allowing the gas to be used as the heating medium. Inert gas is used
to keep a polymer sample from oxidizing and degrading. The gas supply pressure should be 70 to
125 psi (0.48 to 0.86 MPa).
•
Gun Heaters
: Connects to the oven to provide pneumatic output from the test station to the oven. This
port supplies the oven with air or N2 gas.
