10 INSTALLATION CRITERIA
The TQC CureView is designed to operate in general lab conditions on a
sturdy worktable. In order to create the safest work environment possible
below requirements should met.
10.1 Climate
It is recommended to operate the TQC CureView in a temperature stable
environment. Due to the general tests performed with the TQC CureView a
climate controlled environment is advised having 20-25˚C / 68-77˚F and
40 – 60 %rH. Other ranges of temperature and humidity can limit the
minimal programmable temperature of the machine. For example if the
ambient temperature is 35˚C / 95˚F the minimal programmable temperature
is approximately 10˚C / 50˚F higher.
10.2 Power Supply
The TQC CureView is designed to operate at 220 - 240V / 50/60Hz power
supply, this due to the power consumption of 3500W. For the 230V /60Hz
equipped countries the 3500W is together with the laptop the maximum
power that can be drawn from a fuse. The CureView should be run on a
dedicated fuse. The TQC CureView cannot be connected to 110V power
supply. When the TQC CureView is intended for use in 110V countries the
CureView needs to be connected to Split phase power supply. Please
consort a suitable trained technician to verify the power supply.
There should be a second power plug available to
connect the laptop.
10.3 Worktable
A suitable and sturdy table needs to be selected with sufficient depth and
clearance above the table to operate the TQC CureView. No power supplies,
sockets or such may be placed behind the CureView that could block or
be affected by the heat exhaust in the rear of the CureView. The worktable
should be able to support 40 kg / 88.18 lbs of load and allow for placement
of the CureView with following clearances. The height of the table should be
selected such that ergonomic and safe operation is the machine is possible.
Please consult local guidelines and regulations.
10.4 Exhaust system
The CureView has a self-powered fume exhaust system mounted on the
rear. This system is created to allow fumes emanating from the test panel to
be expelled safely. The CureView may be connected to an already existing
ventilation system when this is a system without forced convection. If
the ventilation system has forced convention care should be taken not to
disturb the flow of air in the CureView.

11 THERMAL DYNAMICS
11.1 General
Even though the CureView is designed to the highest specifications possible
the CureView has limitations. We simply are not able to go beyond the laws
of physics. In order to explain some of the limitations of the TQC CureView
the following chapter will include some of the intricacies of thermal
dynamics involved with using the CureView.
11.2 Basics of Gradient Ovens:
The TQC CureView is a new generation of Gradient-ovens that allows for
significantly more advanced tests and doesn’t require preheating. The
implementation of the latest heating techniques in the TQC CureView
provide a different heat transfer compared to that of older systems with
conventional heating. The direct IR-irradiation by the TQC CureView allows
for a significantly more efficient heating than traditional gradient oven
systems. Due to this new heating system multiple components and
procedures had to be changed in the machine. Below is a simplified image
highlighting the difference in build of conventional systems and the new
TQC CureView.
Conventional heating IR-heating
Due to the difference in construction the heat transfer is significantly
different. Where the older systems work based on conduction of heat the
TQC CureView is based on transmittance of energy by IR-radiation. Older
Gradient ovens often suffer from loss in efficiency by improper contact
between the heating element, glass-bed and/or test panel. Because older
models have the thermocouple installed directly at the heater, they have
been compensated for the offset that occurs due to the different contacts
required to transfer the heat. Any small misalignment or other problem will
result in a loss of efficiency. This will cause significant differences in the
temperature of the test-panel. The TQC CureView is created such that it
regulates the heaters based on the temperature probe that is positioned on
top of the panel, thus at the actual spot where the temperature is relevant.
When comparing old and new systems side by side there might be a
temperature offset that has to be accounted for. This off-set is due to
deviation from older machines. Where test were set to be performed at
180˚C / 356˚F they could actually have been performed at 150˚C / 302˚F.
This off-set varies depending on the condition of the old machines.
To determine this off-set it is recommended to measure the actual
temperature obtained on the surface of the test panel.
Due to the new and improved heating systems no preheating is required.
This eliminates an irregular heating of the panel and allows for a repeatable
ramping of the temperature on the panel. The ramping is controlled and will
follow the same slope for all temperatures. The ramping for the heating can
be programmed in the Gradient oven. Below graph shows a default slope
being equal for all set point temperatures.
All following examples of ramping and heating graphs are
generalized and not correlated to a specic substrate or
ramp speed unless otherwise stated.
11.3 Substrate material
The main influence for differences between tests is the substrate that tests
are performed on. Different substrates react differently to heat. Some
substrate function as an isolator and others as an excellent conductor of
heat. This ability or it’s lack to conduct heat determine the maximal
temperature difference between 2 heaters. On a well conducting material
the difference between 2 elements is lower than on a less conducting
substrate. The property of metals to conduct heat is a temperature
dependent function. If a gradient from 25˚C to 125˚C / 77˚F to 257˚F
is obtainable this doesn’t mean that 125°C to 225°C / 257˚F to 437˚F is
possible as well or vice versa. In order to test for the suitability of a program
and/or substrate it is advised to run a test-run on uncoated substrate prior
to performing the real test.
Full thermal properties of a substrate can be calculated. Full calculations
and factors can be found in the “ Handbook of Chemistry and physics.”
Calculating the thermal response of panels is however tricky due to the
large number of variables.
11.4 Surrounding / environmental conditions.
The TQC CureView has been designed such that it will keep draft away
from the panel but still allow the panel to be visible. Though the Cureview
is designed to eliminate as many influences as possible. Small fluctuations
in the heating behavior can be caused by changes in temperature and
humidity of the surrounding air. These parameters not only influence
the heating capabilities of the CureView but in more significant manner
the evaporation of samples as tested according the ISO 2812-5 or curing
of powder coatings. Stable laboratory conditions are required to create
reproducible results. Please consult internal guidelines or international
standards for the required climatic conditions required for the performed
test.
11.5 Ramping
The TQC CureView can be set for custom ramping speeds. A Ramping
indicates the speed in degree per second the CureView will heat a panel.
The selected ramping will influence the amount of heat generated by the
lamps. The generated heat needs to flow from the bottom of the panel to
the top prior to being detected by the probes. This process depends on
the thermal properties of the test panel. Thickness, material type, surface
finishing and set end temperature all influence the thermal response. If the
ramping is set to high there might be an overshoot of the set temperature.
In the following graph the vertical axis shows the temperature in ˚C and the
horizontal axis displays the time (s). All set temperatures follow the same
ramp. Adjusting the ramp value can control the ramp slope.

assigned probe, the heater will move to the Not allocated to a probe
section at the bottom of the window.
Click the Heater windows to rotate the heater order.
File Details:
Use the file tab to view the imported temperature probes in a graph.
12.6 Execute a test in run mode
In the Post-cooling setup the two commands start run and proceed will act
the same way and switch the program into run mode.
Start run:
Command to instantly switch the program into run mode and begin
execution of the configured panel test. Once in run mode this command is
disabled and the cancel run command is enabled, which allows cancel of the
test in any run mode enumerator stage.
Proceed:
Command to begin execute the configured panel test.
Fume fan:
Command to control the exhaust fume fan. Use this control to flow off fume
that may originate from the running test.
12.8 Place panel
The gradient oven carrier is waiting in the loading area allowing placement
of the panel into the carrier.
Once this stage is completed press Proceed.
12.9 Pre-cooling oven
In this stage the gradient oven clamp is lowered onto the heaters to
verify that the heating zone is cooler than the configured oven test panel
temperature. Each probe must measure an actual temperature that is
lower than the target temperature before the gradient oven transports the
panel any further. In case the system temperature is higher the gradient
oven internal fan will switch on at 100% until all probes are measuring a
temperature lower than the configured temperature.
Cancel run:
Command to cancel the current run and switch to program to setup mode.
Use the red button on the front of the gradient oven to obtain the same
result.
12.7 Initialization
In this stage the gradient oven will get ready for run mode. The run stage
enumerator shows the thirteen stages that a panel test follows. The stages
include loading the panel into the oven loading area, where after the panel
is transported to the cooling area followed by a transport to the heating area.
After the test the process is reverted and the panel returns to the loading
area.
Congure a target temperature that is at least higher than
ambient temperature in order to avoid the oven to wait for
a condition that can’t be met.
Transport panel
The panel is transported from loading to cooling area.
Cooling
The panel is cooled down according to the configured Pre-cooling setup.
Transport panel
The panel is transported from cooling to heating area.
Clamp panel
The panel is clamped onto the glass bed by the weight of the probes.

configured heating setup.
Measured temperatures:
The graph displays the measured temperature (blue) vs the configured set
temperatures.
Congured temperatures:
The graph display the set temperatures.
Unclamp panel
The heating stage is ended, the clamp is lifted and the probes are moved
upwards in order to free the panel for transport.
12.11 Lift Panel
The panel is ready and presented to the user for analysis.
Lift panel:
Command to lift or lower the panel in the loading area.
Return to conguration:
Command to switch from Run mode to Setup mode where the next run is
configured.
Transport panel
The panel is transported from heating to cooling area.

13 MAINTENANCE
The TQC CureView is created such that a minimum of maintenance is
required on an annual basis. Due to the temperature resistant materials used
for the production only a hand full of components need to be checked and
maintained. Maintenance of the TQC CureView should only be performed
by competent personnel.
21 |
13.1 HEATER REPLACEMENT
The TQC CureView uses IR heaters to heat the panel. These heaters have a limited life expectancy of
5000 burn hours. It is advised to replace the heaters on an annual basis. Older heaters can influence
the performance of the TQC CureView and limit the ramping capabilities of the TQC CureView, or
cause a significant loss in efficiency. Following procedure should be followed for replacing the
heaters.
1
Turn machine off by using the switch
button on the right side of the instrument.
2
Disconnect power supply and USB cable.
Frequency:
Annual replacement (adviced) or
individual lamp replacement
