Mechanical Safety
This section provides safety information associated with the mechanical functions of the ARES-G2.
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.
1 Prepare the instrument for relocation as follows:
a Remove all samples and geometries, as well as the lower temperature controlling device (which is
mounted on the motor) such as the Sealed Bath, Peltier Plate, Peltier Concentric Cylinders, and
Electrically Heated Plates.
b Turn off the power and all power cords and cables to the power supply.
c Lock the motor and transducer. See Chapter 2
for information.
d Turn off the air/gas supply and disconnect all lines.
e Close the oven (if installed) and secure it.
2 Remove the four corner plugs by pulling them straight out, as shown below. Retain the plugs for use
after the instrument is moved.
3 Follow the instructions on the next page according to the method used to move the instrument, with a
cart (recommended) or without a cart. If you are using a cart, you may move the instrument with two
people. If you are not using a cart, three people are required to move it.
WARNING: Keep your hands clear of the motor while it is running. If you need to
touch it, turn OFF the motor first.
AVERTISSEMENT: Éloignez vos mains du moteur lorsqu'il tourne. Si vous devez
le toucher, arrêtez d'abord le moteur.

4 Install the four carrying handles by screwing them into the threaded holes on all four corners, as shown
below.
Moving the ARES-G2 Using a Cart (Highly Recommended)
1 Obtain a cart that is wide enough to accommodate the instrument, and able to support at least 250 lbs
(114 kg). If possible, raise the cart until the top surface is level with your lab bench.
2 Position one person on the lighter side of the instrument (to the left as you face the instrument), and two
people on the heavy side of the instrument (to the right as you face the instrument). Carefully slide the
ARES-G2 onto the cart.
3 Wheel the cart to the desired location, slide the instrument onto the benchtop, then remove the lifting
handles.

Introducing the ARES-G2
Overview
The TA Instruments ARES-G2 is a mechanical spectrometer capable of subjecting a sample to a dynamic
(sinusoidal) strain deformation, steady shear strain deformation, or a combination of dynamic and steady
strain. The ARES-G2 measures the resultant torque generated by the sample in response to this shear strain.
The figure below shows the ARES-G2 test station equipped with a forced convection oven. Shear strain is
applied by the motor; torque is measured independently by the transducer. Test parameters are set by the
operator, with the actual sample response determined by the motor and transducer.
Figure 1 ARES-G2 test station with Oven.
The ARES-G2 works in conjunction with a controller, TA Instruments TRIOS software, and environmental
units to make up a rheological analysis system.
The controller is a computer that performs the following functions:
Provides an interface between you and the instrument
Enables you to set up experiments and enter parameters
Runs the experiments and stores experimental data
Allows you to calibrate the instrument
Runs data analysis programs
The following pages provide a brief description of the components available with the system.
NOTE: For technical reference information, theory of operation, and other information associated with the
ARESG2 and not found in this manual, see the TRIOS online help.
ARES-G2 Getting Started Guide Page 15

ARES-G2 Test Station
An ARES-G2 test station, shown in the figure below, consists of several components. The primary compo-
nents are the motor, stage, transducer, keypad, touch screen display, an environmental control option, and
various geometries needed for experiments.

Stage
The stage is a motorized platform that supports the transducer. The stage can be raised and lowered to
facilitate sample loading using the keypad on the front of the test station, the touch screen, or through
TRIOS software control. The rate at which the stage moves can be adjusted through software.
ARES-G2 Keypad
The keypad, shown in the figure below, is an external device on the front of the instrument that is used for
several types of control. The indicator lights will show green when that function is on and red when it is
off.
Instrument Power Status Light has five states applicable to the status light. These are:
Blinking green displays when the instrument is powering up.
Steady green indicates that the instrument is fully powered and ready to operate.
Blinking red indicates that the instrument is powering down.
Steady red displays when the instrument is in the standby state.
Light off indicates that the power switch is off at the power supply.
Figure 3 ARES-G2 keypad.
The functions on the keypad are described briefly below:
Environment Button: Turns the environmental control unit, such as the oven, Peltier, etc. on or off.
The light beside the button indicates the state of the environmental unit.
Transducer Light: An light indicating when the transducer is either on or off.
Motor Button: Toggles between motor on and off. The light beside the button tells you the state of the
motor. If the transducer and motor are both off (lights are red), pressing the motor button will also reset
the transducer.
Stage Up Button: Raises the stage. The light beside the button indicates the state of the stepper motor.
Stage Down Button: Lowers the stage. The light beside the button indicates the state of the stepper
motor.

Slew Up/Down Button: When the slew button is used in conjunction with the motor up or down but-
tons, the stage moves very quickly. To slew the stage downward, press and hold both the slew and
stage down buttons. To slew the stage upward, press and hold both the slew and stage up buttons.
Standby Button: Upon pressing this button, the instrument slowly powers down after the oven comes
down to the stabilization temperature of 50°C. Then the power to the instrument shuts off. The light
beside the button indicates the status. To put the instrument immediately into standby mode, press and
hold this button for at least 10 seconds.
NOTE: The lights next to the stage up and stage down buttons indicate the stepper motor status. A single
light next to the button indicates that the mechanical limit has been reached, or that a normal force over-
load has disabled the motor. Both lights lit together indicates that the transducer is not functioning and, as a
result, the stepper is not moving at all.
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.
NOTE: For detailed information on the functions performed with the touch screen, see TRIOS online help.
The Instrument Touch Screen
The Instrument tab of the touch screen displays the main instrument functions and gauges. This allows
you to monitor the current torque, normal force, gap, temperature, and data zones and points. Buttons on
the screen are available to perform gap control, set the temperature, and stop the test.
Figure 4 ARES-G2 Instrument touch screen.
ARES-G2 Getting Started Guide Page 18
The ARES-G2 Status Touch Screen
The 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.
Figure 5 ARES-G2 Status touch screen.
The primary uses of this screen are to provide an overview of all the instrument components and to serve
as a troubleshooting tool.
ARES-G2 Getting Started Guide Page 19
The ARES-G2 Messages Touch Screen
The Messages tab (shown in the figure below) displays status messages that can be used for troubleshoot-
ing.
Figure 6 ARES-G2 Messages touch screen.
The ARES-G2 Settings Touch Screen
The 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.
Figure 7 ARES-G2 Settings touch screen.
ARES-G2 Getting Started Guide Page 20
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. When a
torque or normal force is applied to the FRT shaft, the servo control systems respond by driving the
required current through the torque and normal force motor coils to maintain the shaft null position. The
electrical currents required to maintain these null positions are proportional to the amount of torque and
normal force applied to the shaft. Sense resistors sample these currents, and the resulting voltages are
scaled to provide the torque and normal force signal outputs of the transducer.
Selection and control of torque range is performed using the TRIOS software.
For normal force, full-scale measurements can be made in both the upward and downward directions. The
weight of the shaft and geometry does not reduce the measurement range in the downward direction.
