You must unplug the instrument before doing any maintenance or repair work; hazardous voltages are present in this system. WARNING: There are no customer-replaceable fuses in the ARES-G2. High volt- ages are present in this instrument. If you are not trained in electrical proce- dures, do not remove the cabinet covers unless specifically instructed to do so in the manual.
Lifting/Moving the Instrument The ARES-G2 is a very heavy instrument. Use three people to lift and/or carry the instrument. The instru- ment is too heavy for one person to handle safely. In order to avoid injury, particularly to the back, please follow the procedure below.

ARES-G2 Touch Screen The ARES-G2 instrument has an integrated touch screen display for local operator control. Interactive functions such as gap zeroing, sample loading, and setting temperature can be performed on the instrument touch screen. The functions shown on the screen change depending upon the menu being used. This sec- tion briefly describes the interactive functions shown on the touch screen displays.
The ARES-G2 Status Touch Screen Status tab (shown in the figure below) displays the instrument status regarding air pressure, tempera- ture sensors, system status, and network communication status. It also provides easy access to system information and diagnostics that may be used to troubleshoot your instrument.
The ARES-G2 Settings Touch Screen Settings tab is used to identify your ARES-G2 instrument, its location, and network (IP) address infor- mation. In addition you can perform the normal force tare function, adjust FCO camera focus and light, and calibrate the touch screen.
Transducer The ARES-G2 utilizes a Force Rebalance Transducer (FRT), shown below, to measure torque and normal force generated by the sample. Figure 8 ARES-G2 linear transducer. The FRT consists of independent rotational (torque) and axial (normal force) servo control systems. Each of these systems uses position feedback to maintain the FRT shaft in a constantly null position.
The larger unit on the bottom (see the figure below) is used by the ARES-G2 test station. The smaller top units are designed to be used by the optional environmental units such as the Forced Convection Oven (FCO) or the Peltier Plate system.
CAUTION: Make sure the purge air is flowing when the oven is on. Failure to do so could cause damage to components inside the oven. The purge line connects to the back of the ARES-G2, to the port labeled OVEN PURGE.

La conduite de drainage se raccorde à l'arrière de l'ARES-G2, au port étiqueté DRAINAGE DU FOUR. The oven is a forced convection environmental chamber that encloses the sample. Mounted in the oven are two resistive heaters, which are used to control the temperature of the gas flowing through them.
Lower Air PRT (Used for fast-response temperature control.) Using the default system settings, the ARES-G2 will report and control the measured temperatures that are in closest proximity to the geometry or sample. If Upper and/or Lower Geometry PRTs are connected to the system, combinations of these measurements will be used to control and measure the Oven tempera- ture.
150°C. The LN2 cooler is – connected between an external liquid nitrogen source and the ARES-G2 test station. Controlled by the oven supply enclosure through the software, the LN2 cooler consists of a Dewar flask, a solenoid valve to control liquid nitrogen flow into the Dewar, and hardware to control the boiling of the liquid nitrogen to produce cold nitrogen gas within the flask.
TA. Supported instruments and environmental systems include the DMA Q800 with standard furnace (-100°C), Discovery Hybrid Rheometer models with Environmental Test Chamber (-85°C), and ARES-G2/ RSA-G2 with Forced Convection Oven (-100°C). The ACS-3 features low-noise durable compressors (approx. 55 dB), small footprint, uninterrupted operation, CFC- free, and for specified temperature ranges, eliminates the recurring cost and safety concerns associated with handling and use of liquid nitrogen.

• Connecting the ARES-G2 to the controller computer and network. It is recommended that you have your ARES-G2 unpacked and installed by a TA Instruments Ser- vice Representative. Call for an installation appointment upon receiving your instrument. CAUTION: To avoid mistakes, read this entire chapter before you begin installation.
• A power outlet. An ARES-G2 without an oven, requires from 90 to 264 VAC/ 50 or 60Hz with a 15 amp outlet. Any unit with an oven requires 180 to 264 VAC / 50 or 60Hz with a 20 amp outlet.
The air source going into the dryer should have a minimum pressure of 100 psi (0.68 MPa). Follow the instructions below to install the air dryer. Mount the air dryer to a wall in close proximity to the ARES-G2 to allow the lines to reach the back of the instrument. See the figure below.

Locking/Unlocking the Motor When you first receive your ARES-G2, the motor will be locked with a motor cover. See the figure below. Unlock the motor as directed below BEFORE powering up the instrument. Remove screws Figure 35 Motor cover installed.
Ensure that instrument power is off and air is being supplied to the motor. Turn the locking handle toward the back of the instrument as shown in the figure below. Locking handle Anvil pointing toward back Figure 36 Transducer unlocked. ARES-G2 Getting Started Guide Page 57...
Figure 37 Transducer locked. Connecting Accessories Follow the instructions in the associated manual or online help for instructions on connecting any accesso- ries to the ARES-G2. To install the various geometries, see Chapter 3 for basic instructions. See the online help for geometry- specific information.
Connecting the Test Station Power Cable Once all cables and lines have been connected to the modular power supplies and the ARES-G2 test sta- tion, connect the power cable. Install the power cable as follows: Make sure the power switch on the lower power supply module is in the Off (O) position.
Leveling the ARES-G2 The ARES-G2 is levelled using the feet, or levellers, located on each corner. Note that the right rear level- ler is fixed in position; therefore, you will be adjusting the other three levellers. Follow the instructions below to perform this procedure.
Shutting Down the ARES-G2 Should you need to shut down the ARES-G2, simply press and release the standby button on the front panel. This will safely power down the instrument as soon as the oven comes down to a safe operating tem- perature.
If an error occurs that causes the instrument to not switch into the standby state, the press and hold the Standby button continuously for 10 seconds to force a shutdown to occur. Powering Off the ARES-G2 If the instrument is expected to be disassembled for maintenance, disconnected from its compressed air source, or is being moved, then it is necessary to turn the power to the system completely off.
Use, Maintenance, & Diagnostics Using the ARES-G2 All ARES-G2 experiments follow the general outline below. In some cases, not all of these steps will be performed. The majority of these steps are performed using the instrument control software. The instruc- tions needed to perform these actions can be found in the online help in the instrument control program;...

• Calibrated the ARES-G2, if necessary. WARNING: HIGH VOLTAGE is used in this instrument. DEATH ON CONTACT may result if operating personnel fail to observe safety precautions. Learn the areas of high voltage connections, and exercise care not to contact these areas when performing instrument calibration.
Calibrating the ARES-G2 To obtain accurate experimental results, calibrate the ARES-G2 when you first install it. For the best results, you should recalibrate periodically. The calibration procedures that you need to perform will vary. See the chart below for a general guide to types of calibration. For details on how to perform that cali- bration, refer to the online documentation accessed through the TRIOS software.
To check the phase angle using the ARES-G2, a Dynamic Frequency Sweep is run on a steel sample that is loaded into a torsion rectangular geometry. Recall that a purely elastic sample has a phase angle of zero degrees.
The ARES-G2 utilizes an online hardware correction scheme to adjust for transducer compliance. The sys- tem determines sample deformation (strain) by taking the difference between the (measured) motor and transducer displacement signals.
