Introduction
The TR-EVO temperature controller is a valid tool to adjust temperature in heating elements,
ithout using external sensors.
By taking advantage of the voltage-current characteristic, the TR-EVO manages to maintain the
temperature set even in conditions of high heath loss, thereby obtaining considerable benefits
compared to traditional methods used.
To reach the temperature set in the least time possible (100 ÷ 350 ms) and keep it constant means
obtaining an increase in operating speed, but also an extended operating life of the heating part,
and enables less aiting times due to thermal inertia or dispersions of the various metal parts
supporting the heating element.
The TR-EVO as designed to be controlled or control, from the simplest electro-mechanical
packaging machines to the most complex packaging lines ith PLC or PC.
All the operating parameters can be entered using the display or the integrated serial port RS485.
Extremely easy to use, highly functional and compact, this system is the strength of heat sealing
processes, including ith hot air, temperature control, hot cutting, etc...
arnings
ATTENTION: for correct use of your temperature controller, it is essential to
comply with the instructions in this manual. You are advised to read each part of it
carefully before start up, to prevent possible damage due to improper actions.
Avoid installing the equipment in the immediate vicinity of high power units, relays,
motors, etc.
The equipment is NOT equipped with an ON/OFF switch, therefore it switches on as
soon as it is connected to the power supply.
The power supply should have adequate protection against any short circuits or
anomalies on the equipment.
Install connections using cable types with adequate sections for the voltage and
current limits specified in the manual.
Check the system has a good ground connection.
Do not use the equipment in environments with a dangerous atmosphere
(inflammable or explosive).
TR EVO operation implies use of specifics alloys for the heating elements. Use of
different alloys can cause the TR EVO to malfunction with possible temperature
instability and/or dangerous overheating.

Operation
Principles
The temperature controller adjusts the temperature of a heating element ithout using probes, but
by basing itself on the variation characteristics of the resistance, on temperature variation, hich
is characteristic of each heating element. Measuring the voltage and current sent to the heating
element enables calculation of its resistance and by comparing it ith that of the cold detected
element during the "tuning" phase, the temperature can be found on measurement. Based on these
calculations, the po er necessary to bring or maintain the temperature set is calculated and a solid
state s itch is activated to provide the necessary po er to the heating element. Thanks to the high
speed ith hich this measurement is taken (50 times per seconds) very fast adjustment ith
good temperature stability of the heating element is possible. Heating times of 150ms. are normal
for this equipment and no particular measures are required to reach them. At the same time, the
temperature can be kept constant also in very lo po er request conditions, allo ing heating to
be kept continuously on.
Operating modes
The temperature controller can ork autonomously using the integrated display and keypad, or
can be connected to a PLC control device or PC using an EIA/TIA485 interface, or can be
adjusted by external analogue voltage or by a panel potentiometer.

Po er transformer
Positioning of the transformer is constraint-free, but you are
advised to assess it based on the cable length. It is good practice
to optimise the length of the cable, especially the part connected
to the secondary.
If possible, avoid dividing the cable into sections using terminals.
The dimensions of the transformer are variable and depend on the
application. See chapter for calculation.

Caution: To obtain correct measurements, this cable must be connected to the ends of the heating
element, connecting at other points introduces measurement errors and reduces the efficiency of
temperature control.
Current measurement input
To sense the heating element current, TR-EVO has a dedicated
passage here to pass one of the connecting cables bet een
transformer and heating element. Normally the cable only makes one
passage through the hole. In particular cases and depending on the
characteristics of the heating element and/or the transformer, the
number of passages to be made could be more than one. See in the
figure on the side of this paragraph ho to make t o passages. Do
reference to the section "Transformer sizing" for more information.

Transformer dimensioning
Considering the voltage of the primary should be the same as the po er supply voltage of the
temperature controller and then 230Vac or 115Vac, another t o parameters must be defined:
voltage to the secondary and transformer po er. To calculate these parameters, start ith the
quantity of energy necessary for the operation, ho ever for simplicity purposes it is considered
that to heat a bar to approx. 200°C in approx. 200mS a specific po er of 30W per cm2 is needed
on the outer surface of the heating element.

The formula:
r = Cs × Lu × La  Sp × 2
enables calculation of the maximum po er Pr required by the heating element, here:
Cs = surface load in Watts per cm2. This value determines the speed the bar heats and assumes,
as seen above, a reference value of 30. Naturally, this value can be changed if higher speed
is required, or less po er supply is available, or po er that exceeds the maximum that can
be supplied by the controller.
Lu = heating element length in centimeters.
La = heating element idth in centimeters.
Sp = heating element thickness in centimeters.
And its resistance R in ohm is:
ℜ= Rs × Lu / 100
here:
Rs = Specific resistance of the band in ohm/meter
These values are used to calculate the secondary voltage Vs of the transformer in volts according
to the formula:
Vs =

r ×ℜ
The po er of the transformer Pt must be calculated in Watts using the formula:
t =r×1,1
here 1.1 is a constant to compensate transformer losses.
In addition, e can calculate the peak current I in Amperes requested by the load hich is orth:
I=r

"Hardware" configuration
Based on the current calculated, the s itches must be configured on the temperature controller
and in particular: if the current is over 50A both s itches should be closed, if the current is
bet een 25 and 50A s itch 1 should be closed, if the current is bet een 11 and 25A the s itches
should be left open.

Start-up
On first start up, the equipment will probably give an error signal.
This signal is normal and depends on the fact the parameters of the
heating element have not been registered yet. For the temperature
controller to acquire these parameters, the Tuning procedure must
be activated which should always be executed after replacing the
heating element.
The tuning procedure enables the temperature controller to acquire the cold resistance value of
the heating element and starts ith the specific sequence indicated in the programming chapter or
from remote via interface 485. At the end of the procedure, the temperature controller ill start
orking properly again or blocks, displaying an error that indicates the reason the procedure did
not conclude properly.
Always execute the tuning procedure with the heating element at
room temperature.
On s itch on, the temperature controller prepares for operation by synchronising ith the mains
frequency and displaying it on the numerical display, (F 50 for 50Hz) .
Once synchronised, the temperature controller goes to "standby" mode and displays
the temperature read on the heating element. To read the temperature, the po er
output is briefly activated at a fixed rate, allo ing the device to continuously control
the load status and promptly signal any anomalies. If the device detects anomalies in
its operation, it blocks and signals the type of anomaly on the display and activates a
signal output.
In standby mode, the equipment does not adjust the temperature and displays the
temperature read on the heating element. Heating starts if the pre-heating and/or
START input are activated. These commands can also be serially activated, ho ever
the response time is not guaranteed therefore you are not advised to use them in
situations here the response time is important.
The operating status of the temperature controller is indicated on the leds on the left of the second
ro of the display. The first led on top indicates heating has started by applying voltage to the
START input, ho ever the temperature has not yet reached the value set or start of heating cicle
delay timer(td) is still active. When the temperature reaches the orking value, the central led
s itches on as long as the START input is active or until the pulse timer(to) expires. Lastly, the
bottom led s itches on hen heating has concluded, ho ever the heating element has not yet
cooled do n or cooling timer has not yet expired.
The orking temperature can be set using external voltage controlled by a
potentiometer or an analogue output, using the serial interface, or directly from the
keypad on the display. To set the orking temperature, press the
≡
key to display
the temperature, indicated by the abbreviation ht on the lo er display, and press the
and keys to edit the value.

access the equipment configuration is enabled (for information on the configuration, refer to the
relevant chapter).
Press the
≡
key again to display the temperature read on the heating element again.
For test purposes, you can press the key to force activation of the heating cycle.
Operating modes
The temperature controller can be configured ith various operating modes.
In brief, the available modes are:
interactive:
by doing so, the pre-heating input allo s you to activate
temperature control at the pre-heating temperature (2) and the
start input allo s you to activate the temperature control at the
heating temperature (4). The start input has priority over the
pre-heating input.
On reaching the orking temperature (3), the active cycle
output activates.
On deactivating the heating input temperature goes lo and
active cycle output deactivates.
Always on:
in this mode, temperature control is al ays on and
continuously adjusts the pre-heating temperature. Activating
the start input, the adjusted temperature changes to the heating
temperature.
On deactivating the heating input temperature goes lo and
active cycle output deactivates.

Timed:
in this mode, hen the pre-heating input is on, it activates

phases. The first phase (indicated ith the TD led on the display)
delays heating starting for the time set on the relevant timer. The
second phase (indicated ith the TO led on the display) adjusts
the heating temperature for the time set on the relevant timer. At
the end of the cycle, the equipment aits for start input disabling
to re-start a ne cycle. The cycle can be stopped at any time by
disabling the START signal.
Pulse:
in this mode, the start input is used to start the timed cycle

The phases are: (4) delay, adjustment activates at the pre-
heating temperature, ho ever heating is delayed for the time set
on the relevant timer. This time is used hen it is not possible to
have the START signal activated at the right moment. (5)
Heating, the temperature is brought to the ork value for the
time selected on the relevant timer. (6) Cooling, the heating
element is no longer po ered and hen the temperature is
belo the value set on the relevant parameter or on expiry of
the relevant timer, the cycle concludes by disabling the cycle
output.
System and alarm monitoring
When on, the temperature controller continuously controls operations are proceeding correctly
and if errors are found that prevent proper operation, blocks and signals the cause of the error.
Signalling is implemented via contact of a relay that signals the tool condition to the operating
machine, using an error number displayed on the numerical display, and transmitted instead of the
temperature on the serial interface.

Warning: The counter may continue to restart even if you press and hold the button signalling
that the conditions are not right to start the procedure. Probably the heating element is not yet at
room temperature, temperature required for success of the "tuning" phase, or the device is active
in heating mode. Release the button, disable heating, and ait a fe minutes before trying again.
At this point, the first top led s itches on to indicate the procedure, divided in 3 parts, has started.
After approx. 1-2 minutes, the procedure ill end displaying, if everything as successfully
completed, the three flashing leds and t o numbers on the display. The
≡
key allo s you to
return to normal operation ith temperature display. (for further information on the procedure,
refer to the relevant section of the manual)
Extended parameters
The TR-evo operation is configured by adjusting another set of parameters, called extended
parameters hich can be accessed ith the follo ing procedure:
To access the extended configuration parameters, bring the bottom display to value
10 using the key hen the top display sho s CFG and then press

.
The display then sho s the first extended parameter indicated by the parameter code
on the bottom display. If you do not ant to edit the value, press the
≡
key to go to
the next parameter, other ise the and keys edit the value and the

key saves
the parameter in the temperature controller non-volatile memory.

The configuration parameters available are in sequence:
code 11 Max settable temperature for pre-heating. Configure the adjustment limit of the hP
parameter. The absolute maximum that can be set is 100°.
code 12 Max settable temperature for heating. Configure the adjustment limit of the parameter
ht. When the adjustment ith potentiometer is used, this ill adjust bet een a minimum set
ith the parameter ht and this maximum value. The absolute maximum settable is 500°.
code 13 Operating mode. See operating modes section of the manual
0 = adjustment only activates hen inputs activate at the relevant temperatures set
1 = adjustment activates at the input pre-heating temperature for heating.
2 = timed heating cycle aborts if input removed.
3 = timed heating cycle after impulse on heating input.
code 14 Timers unit of measurement selection. It allo s to operate ith times up to 99.9 sec.
CEn (timing in hundredths of a second)
dEC (timing in tenths of a second)
code 15 Select temperature unit of measurement.
C (degrees Centigrade)
F (degrees Fahrenheit)
code 1 Analogue input voltage selection. Allo s you to adjust the temperature ith a
potentiometer connected to the device or ith an external 0-10V voltage connected instead of
the potentiometer.
POt input 0-5V ith potentiometer
U01 input 0-10V
code 17 Alloy used in heater. Indicates to the TR-evo hich material the heating element is made
of, to allo the correct temperature indication.
1 = Nichrome40
2 = AISI 316
3 = Alloy20
4 = MS500
5-9 = Others
code 18 Increment at minimum firing TRIAC This parameter allo s you to change ho the
heating element is po ered to improve performance in certain specific cases. The parameter
can take values bet een 0 and 20. Normally it should be left at 0.
code 19 Loop gain setting. It allo s to adapt the temperature control according to the specific
po er used in particular situations. The parameter can assume values bet een 0 (very lo
gain, hen specific po er is very high) and 30 (high gain to try to compensate very lo
specific po er). The default value is 5 valid for most configurations.
code 20 Serial bus mode. Select communication format depending on the other connected
devices.
72 = (7 + 2stop)

73 = (7 + EVEN )
74 = (7 + ODD )
1 = (8 + NONE )
2 = (8 + 2stop )
3 = (8 + EVEN )
4 = (8 + ODD )
code 21 Serial bus speed. As the previous parameter adapts communication to others connected
devices.
19 = 19200b/s
24 = 2400b/s
4 = 4800b/s
96 = 9600b/s
code 22 Device bus addres. Selects the number of peripheral devices that the TR-evo assumes in
the communications bus, its function is to allo multiple devices to connect to the same
communications port ithout interfering ith each other. Device address 58 is reserved and
must not be used on the bus that contains TR-evo devices.
On code 23, the display sho s rEt and allo s you to exit parameter programming
status by pressing the

key.
The
≡
key returns you to the beginning parameter 11 display.
Maintenance
ATTENTION: before carrying out any maintenance operation, ensure you have
disconnected power.
The temperature controller does not require particular maintenance, ho ever you are advised to
every no and then check all the connections are tight, especially those going from the
transformer to the heating element that carry very high current peaks.
The front of the keypad and the numerical display should be cleaned ith a clean, et cloth and
neutral detergent. The dirt on all the other parts should be removed ith compressed air.
