2.0 MAIN MENU

TE70 IR-HEATER

Allows the user to access the TE70 heater's manual work mode. This
mode is used when a part needs to be heated through constant heat
without the control unit having any limits on the temperature that the
heated part can attain.

PAGE 4

TE70 IR-HEATER

Allows the user to access the TE70 heater's automatic work mode. This
mode is used when a part needs to be heated at a temperature defined
by the user and when the user wants to prevent the temperature of the
heated object from exceeding the set value, even in case of prolonged
exposure to infrared radiation. The TE70 heater will modulate power so
that the object to be heated will not exceed the temperature set on the
control unit.

Allows the user to access the TE70 heater's profile work mode. This
mode allows the generating of a temperature profile that varies over
time and that features up to 5 different temperature values. Heating,
according to a variable thermal profile, is useful to reduce paint drying
time or polymerization time of structural adhesives.

3.0 MANUAL WORK MODE

This work mode is used when you want to heat the object by providing
a constant amount of heat to it, without any control on the maximum
temperature the object will reach during the heat application time. The
user can adjust the power delivered by the heating tool; power
adjustment will affect the object's maximum temperature and heating
speed.

Buttons to adjust the percentage of power that must be delivered by
the heating tool.

The heated surface's temperature is measured through the
temperature sensor built-into the tool. The maximum temperature the
sensor can measure is 240°C; if the object is heated to above this
temperature, the sensor will no longer provide the temperature reading
until the object's temperature drops to below 240°C.

In the event the surface subjected to infrared radiation is heated to
above 240°C, the temperature sensor built-into the tool will not be
damaged.

The precision in indicating the temperature of the object for
temperatures below 240°C is related to the calibration of the sensor
according to the surface to be heated.

The user manages the duration of the heating process through the start
button on the heating tool handle.

TE70 IR-HEATER

4.0 AUTOMATIC WORK MODE

This work mode is used when you want to heat a surface by controlling
the maximum temperature it can reach during the heating process. In
this case, the user sets two parameters: the maximum temperature the
surface to be heated can reach and the power that must be delivered by
the heating tool. The setting of the power delivered by the tool allows
you to adjust the speed with which the required temperature will be
reached on the surface of the material subjected to infrared radiation.
On reaching the temperature set on the TE70 heater, the control unit
will begin to modulate the power delivered to the tool to maintain
constant the temperature of the heated surface.

We recommend using high power values when working on matt
surfaces or when you want the piece to heat quickly. A lower power
value is advisable in the case of glossy surfaces or when you want a more
uniform distribution of the heat delivered within the material to be
heated.

The temperature setting at which to heat the surface can be in a range
between 50°C and 240°C.

For correct temperature measurements, it is essential to calibrate the
sensor built-in the tool according to the type of surface to be heated.

5.0 TEMPERATURE PROFILE WORK MODE

The temperature profile work mode must be used every time you want
to generate variable-temperature heating over time, the temporal
duration of which is determined a priori. The variable-temperature
profile work mode is useful to reduce the paint drying time or the
polymerization time of the structural adhesives.

The profile generated by the TE70 heater can contain up to 5 program
steps: each step is characterized by power delivered by the heating tool,
by a temperature value the heated surface must reach and by time
duration.

After setting the temperature profile, simply place the tool on the
surface to be heated and lock the Start, through the appropriate button,
on the tool's handle in the ON position. The TE70 heater will perform
the programmed profile steps in sequence and at the end of the
execution the tool will automatically stop delivering heat.

The maximum duration of each step can be 4 hours for a total maximum
duration of the heating process of 20 hours.

The setting of the power delivered by the tool allows the adjustment of
the speed with which the required temperature will be reached on the
surface of the material subjected to infrared radiation. On reaching the
temperature set on the TE70 heater, the control unit will begin to
modulate the power delivered to the tool to maintain constant the
temperature of the heated surface.

5.2 TEMPERATURE SETTING

When you press the indication of the temperature at which to heat the
surface, a numeric keypad will appear with which to set the temperature
the heated surface must reach during the current step.

When the heated surface reaches the temperature value set on the
control unit, the TE70 heater will begin to modulate the power delivered
to the heating tool to maintain the temperature of the heated surface
at the same value set on the control unit.

Before starting the execution of a heating profile, it is crucial to calibrate
the temperature sensor in the heating tool using the appropriate
calibrator to be sure to have an accurate temperature reading.

5.3 POWER SETTING

When you press the indication of the power to be delivered, a numeric
keypad will appear with which to set the power that must be delivered
by the heating tool during the profile's current step.

We recommend using high power values when working on matt
surfaces or when you want the piece to heat quickly. A lower power
value is advisable in the case of glossy surfaces or when you want a more
uniform distribution of the heat delivered within the material to be
heated.

PAGE 17

5.4 SETTING THE STEP DURATION

If you press the duration of the current step, a numeric keypad will
appear with which to set the time duration of the profile's current step.

If you set a current step duration of 0, the TE70 heater will skip the
execution of the current step and go to the next step, if present;
otherwise it will stop delivering power to the surface to be heated.

When you press the start button on the heating tool, the field reserved
to the duration of the current step will show the time remaining to the
end of the step.

Step duration is displayed in hh:mm format.

9.0 TEMPERATURE SENSOR CALIBRATION

The temperature reading of the surface to be heated, performed by the
sensor built into the heating tool, is influenced by the finish and the
color of the surface itself. Therefore, in order to have a correct reading
of the surface temperature before starting work, you must calibrate the
temperature sensor using the appropriate calibrator.

Calibration should be performed each time you power on the machine,
when you connect a different heating tool and every time the surface to
be processed changes color or finish.

PAGE 23

TE70 IR-HEATER

Calibrate the sensor using the appropriate calibrator on an area of the
surface to be heated, possibly a flat area.

- Set the calibrator orthogonal to the surface on which the heating

process will be performed.

- Press and hold down the “PUSH CALIB” button.

- The calibration process requires from 30 seconds to 1 minute.

- At the end of the calibration process, the “CALIB” LED stays on

and the control unit will emit 3 beeps to confirm calibration was
performed.

- Release the “PUSH CALIB” button and put the calibrator back in

its seat.

N.B.: use the calibrator only on surfaces at room temperature; if the

surface to be calibrated had been previously heated, wait until it cools

down before placing the calibrator on the surface. The use of the

calibrator on hot surfaces can damage the calibrator.
