1. Safety instructions and warnings
1.1. General safety instructions
The safety instructions and warnings given in this description must be followed to guarantee
safe operation of the equipment. The equipment can be operated without impairing the operational
reliability if the conditions stated in the technical specifications are observed.
The equipment may only be installed and started-up by suitably trained personnel.
Maintenance and repair of the equipment may only be carried out by trained personnel, who are
familiar with the dangers and guarantee conditions.
1.2. Application
The PIREG-D2resistance temperature controller may only be used for the heating and temperature control
of heating conductors as specified in accordance with the safety instructions, rules and regulations for
such applications.
Non-observance of the instructions or incorrect use of the equipment can result in impairment of the safety
or overheating of the heating conductor, the electrical wiring or the transformer.
1.3. Note on the heating conductor
A basic precondition for the function and safe operation of the complete heating system is the application
of suitable heating conductors.
The positive temperature coefficient of the heating conductor used must be equal or greater than the positive
temperature coefficient set at the PIREG-D2. The appropriate temperature coefficient of the heating conductor
must be set on the display unit of the PIREG-D2or via the interface. The temperature coefficient of the heating
conductor must be positive over the entire temperature range.
Caution: Using heating conductors with too low a temperature coefficient, or adjusting the
controller to a temperature coefficient that is too high, can result in uncontrolled overheating or
melting of the heating conductor.
Temperature regulation of heating conductors connected in parallel must be more precise than of heating
conductors connected in series. However, the wiring must be strictly symmetrical and performed in such a
way that no overcurrent arises when two heating conductors on opposite sides contact each other.
If series-connected heating conductors have to be used, the effect on the overcurrent reaction should be
taken into consideration if two opposite sealing bands touch each other.

4
1.4. Note on the sealing transformer
The sealing transformer must be configured according to EN 60742 (VDE 0551) (isolating transformer with
reinforced isolation). All types and designs that comply with the standards can be used as sealing
transformers. The induction in the transformer's iron core must not be reduced as is normally the case with
primary side thyristor operation. Transformers with low losses are disrupted less on the secondary side than
transformers that have low energizing currents. Thus in applications with short heating and sealing times, stiff
and generally larger transformers should be used. Where a great deal of sealing is to be performed, a
transformer with a primary voltage of 400 V is advantageous, because this way, the PIREG-D2's internal
actuator is more likely to be sufficient and an external actuator with solid-state relay will not have to be used.
Caution: There must be sufficient protection against accidental contact if the transformer is
installed in a machine frame. Furthermore, ensure that water, cleaning liquids or conducting liquids
do not come into contact with the transformer. The conductor wiring cross sections should be
designed to match the actual currents. Non-observance of these notes may result in impairment
of the electrical safety.
For best results, the transformer's performance and the secondary voltage must be suited to the heating
conductor. A short heat-up period is reached with of a high transformer output voltage. However, the voltage
selected should not be too large so that not less than 12 controller measurements are needed for a target
temperature increase of 300°C when heating up (heat-up period (>240 ms). For smaller heat-up curves,
correspondingly fewer measurements are necessary. (The PIREG-D2takes a measurement every 20 ms while
heating).
The larger the transformer's secondary voltage for a given heating conductor, the more energy is fed into the
heating conductor, even in the "off" state. This is done by means of temperature measuring pulses, which the
controller regularly sends to the heating conductor. Therefore, the higher the secondary voltage of the
transformer the greater is the difference between the resting temperature and the ambient temperature in the
"off" state.
1.5. Note on the current transformer
The current transformer is an essential part of the control system. Only Toss current transformers may be
used. The current transformer mayonly be operated with ballast resistance. The ballast resistance is integrated
into the PIREG-D2. The current transformer must be mounted in such a way that magnetic leakage fields from
the sealing transformer or other leakage fields do not affect the measurement.
1.6. General assembly instructions
The PIREG-D2resistance temperature controller is only suited for use in a switch cabinet. Open operation is
not permitted.
The controller is designed for installation into the switch panel and the current transformer is fitted on a 35 mm
mounting rail according to DIN EN 50022. When installing the controller in the switch panel, there must be a
distance of at least 20 mm from the neighbouring device. Heat dissipation from neighbouring devices must be
taken into account (note the ambient temperature specifications).
1.7. Maintenance
The PIREG-D2resistance temperature controller does not require any special maintenance. However, an
occasional check or tightening of the connection terminals is recommended. Dust deposits on the controller
can be removed with dry compressed air once the power has been switched off.
1.8. Validity
The first device version (v.vv) shipped was the version 1.00 with program versions 1.13 for the display unit
(d.dd), 1.16 for the electrically isolated side (g.gg) and 1.10 for the instrumentation side (m.mm).
Supplements in this description which are only valid from a later version include the version, the notation
Vv.vv/d.dd/g.gg/m.mm, e.g. V1.00/1.13/1.16/1.10 from which they are valid. The device and program versions
are read from the Information menu or by a command (LVERS) via the interface.
2. Short description
The PIREG-D2resistance temperature controller is a controller with integrated sequence control used for
temperature control of heating conductors for heat-impulse sealing of foils and for the control of film sealing
machines.
The sealing transformer is switched by the PIREG-D2on the primary side. The heating conductor is fed from
the secondary side of the transformer. The measuring signals are received directly at the heating conductor
and are made available to the controller.
The PIREG-D2resistance temperature controller has four control inputs and three relay outputs for control of
the film sealing machine. The PIREG-D2resistance temperature controller can control a film sealing machine
independently via these inputs/outputs and the integrated sequence control. The three relay outputs are
divided into one message output and two control outputs with different capacities. In addition there is an alarm
output.
The temperature coefficient of the heating conductor must be positive. Its resistance increases when it is
heated. This effect is used for temperature control. The temperature controller measures and regulates the
resistance of the heating conductor. The temperature coefficient is a material constant that depends on the

5
alloy used for the heating conductor. The actual temperature is determined by measuring the voltage and
current.
The PIREG-D2operates as a proportional control unit that independently determines the P-factor (the control
amplification) for the controlled system of a process during calibration. The controlled system consists
of a sealing transformer and a heating conductor. The P-factor determined during calibration can afterwards
still be corrected by a command or an adjustment in the display unit ( 5.2.5. and 4.9.).
The PIREG-D2is operated via the integrated display unit ( 5.) with 5 keys ( 4.1.) or via the RS232- or
USB interface ( 4.5. –4.9.) fitted at the PIREG-D. Combinations of both types of operation are possible.
An LCD-module with eight lines with twenty-one digits each is used as display.
The PIREG-D2is set to the temperature coefficients of the heating conductor ( 5.7.1. and 4.9.). The
PIREG-D2can also determine the actual temperature coefficient of a heating conductor itself by means of a
temperature coefficient correction ( 5.7.4. and 4.9.). Connect the PIREG-D via the RS232 interface to an
external TM6 thermometer which measures the actual temperature of the heating conductor ( 4.5.2.) to
simplify the temperature coefficient correction. Depending on the setting, the PIREG-D2can operate up to a
temperature range of 500 °C.
During calibration, the controller sets itself to the secondary voltage of the transformer and the current through
the heating conductor. The secondary voltage of the transformer maybe within a range of 1...80 V. The current
measured with a current transformer can range from 20 to 400A. The calibration values can be stored in the
PIREG-D2, so that there is no need for renewed calibration and start-up time after switching on the power
when conditions have not changed.
The PIREG-D2carries out calibration in a variable room temperature range of 0…50 °C. The actual reference
temperature must be set in the display unit of the controller ( 5.7.2.). This is advantageous in the case of
constant sealing temperatures with different environmental conditions.
High quality sealing transformers, such as toroidal core transformers, are switched on by the PIREG-D2on the
primary side. A smooth switching procedure is employed that compensates for the remanence of the sealing
transformer. An initialising remanence setting is made automatically after switching on the power and following
calibration. Only a short remanence setting lasting 40 ms for El core transformers and 80
ms for toroidal core transformers is needed before each sealing process. If, with toroidal core transformers,
the pause between two sealing processes is longer than 10 minutes, the remanence setting takes
160 ms. The remanence is the residual magnetization in the transformer's iron core. During the initial
remanence setting procedure, the heating conductor has to be heated for a short time to approx. 40 to 70°C.
The PIREG-D2itself uses a phase angle controller for temperature control.
3. Functions
3.1. Control
The following settings which must be carried out prior to calibration are available for the PIREG-D2controller.
The PIREG-D2automatically adapts to the Vr voltage and the Ir current of the heating conductor and to the P-
factor (control amplification).
3.1.1. Heating ramp: The heating ramp is used to set the time value during which the controller adjusts the
actual temperature to the target temperature in a linear ramp ( 5.7.3.). This allows the heating conductor to
be heated gradually.
3.1.2. Setting the temperature coefficient: The temperature coefficient of the heating conductor which must
be positive must be set on the PIREG-D2( 5.7.1.). The temperature coefficient is a material constant that
depends on the alloy used for the heating conductor.
Caution: Using heating conductors with too low a temperature coefficient, or adjusting the controller
to a temperature coefficient that is too high, can result in uncontrolled overheating or melting of the
heating conductor.
The actual value can then not reach the target value and the controller continues to heat continuously.
The variable temperature coefficient setting must be used for heating conductors with a temperature coefficient
that differs from the four possible coefficients.
3.1.3. Calibration reference time: The heating conductor resistance is determined at the reference
temperature during calibration ( 3.2.). To ensure that the reference resistance value determined is correct,
the resistance of the heating conductor is measured again after the calibration reference time has expired, and
compared with the determined reference resistance measured previously. If the difference between both
measurements is greater than 1.2% a new calibration process is started. This ensures that calibration of the
PIREG-D2does not take place during cooling of the heating conductor. By extending the calibration reference
time, changes in the resistance of the heating conductor during cooling can be detected more quickly.
3.1.4. Temperature range: The PIREG-D2controller has four fixed working temperature ranges 200, 300,
400 and 500 °C to be selected and a variable temperature range of 100…500°C. The limits for the overand
undertemperatures are chosen accordingly (nominal value +20% or -10 °C respectively).

6
3.1.5. Calibration mode:
- New calibration: If the calibration mode “new-calibration“ is chosen, the PIREG-D2performs a calibration
after every power-on or the signal “Reset”. The calibration values are not saved. Calibration can also be started
in the Off- or error state with the signal “Calibration Start”.
- Save calibration: Calibration is only started with the signal “Calibration Start”. The signal “Calibration
Start” can be applied in the Off- or error state or before power-on. The calibration values are stored in a
non-volatile memory and cannot be deleted by a power on or the signal “Reset”. This means that a new
calibration must be performed after the heating conductor configuration was changed or modifications were
carried out on the transformer. The saved values are then overwritten with the newly determined values.
3.1.6. Transformer type: The PIREG-D2must be adapted to the sealing transformer type (El or toroidal iron
core). For the first power on several unipolar phase controls are applied to the transformer and the remanence
in the iron core of the transformer is set in a defined position. The angle of current flow of the phase angle
control for remanence setting must be matched to the transformer type. The quick switch-on procedure is used
for every sealing during which only a few remanence-pulses are applied to the transformer before it is switched
on. If the pause between two sealing processes is longer than 10 minutes for toroidal core transformers the
number of the remanence pulses of the quick switch-on procedure is doubled.
The soft switch-on procedure is used for switching on high-quality transformers without power surges.
3.1.7. Reference temperature: The reference temperature is the ambient temperature for determining the
reference resistance RBez of the heating conductor during calibration. The reference temperature for the
PIREG-D2can be set from 0 to 50 °C.
3.1.8. Temperature coefficient correction: The PIREG-D2has two temperature coefficient corrections which
can correct alloy-dependent dispersions of the heating conductor materials.
- Temperature coefficient correction: With the standard temperature coefficient correction the heating
conductor is heated in eight temperature increments. Upon each step the value is compared with the actual
temperature of the heating conductor dependent on the actual value correction. The standard temperature
coefficient correction is an essential part of the calibration ( 3.2.) and is carried out during calibration.
- Single-point temperature coefficient correction: With single-point temperature coefficient correction only
one single operating point is corrected. The single-point temperature coefficient correction is carried out
outside the calibration and is started from the Off-state.
3.2. Calibration:
During calibration, the PIREG-D2independently adjusts to the combination of sealing transformer and heating
conductor. At the same time, the voltage "Vr" at the heating conductor and the current "Ir" through the heating
conductor are measured every second. This status is indicated by the corresponding operating status symbols
in the symbol field of the Working menu on the display unit (_ 5.3.). The three relay outputs of the PIREG-D2
can output a ‘Calibration Ok’ message with a corresponding setting which is reset during calibration. Additional
information about the individual calibration steps are displayed on the actual value display or output. The actual
value is updated every second.
The calibration process will undergo the following steps:
3.2.1. Initialisation: During initialisation, the PIREG-D2determines the data necessary for calibration. In
addition, it checks the selected temperature coefficient for dynamics and continuity in the selected temperature
range. Should the dynamics and continuity exceed the permitted limits, the PIREG-D2will stop the calibration
procedure with error 133 (parameter error).
3.2.2. Calibrating the input amplifier: The input amplifiers for Vr and Ir are adjusted in steps to the voltage
and current at the heating conductor. During this calibration step the actual value display shows different
values every second and various voltages are applied to the actual value output every second. The measured
current or voltage value is displayed or output alternately.
The actual value display shows the current within 0 to 50% of the set temperature range of the controller and
the voltage within 50 to 100%. The zero point of the measured values is set at 50 %. At the beginning of the
calibration, the amplifiers (for Vr and Ir) are initialised with minimum amplification. At the end of the calibration
procedure, if the adjustment has been made successfully, the range for the displayed current value is from 16
- 33 % and the range for the displayed voltage value is from 66 - 83 %.
The current displayed at the actual value output is in the 0 - 5 V range, the voltage in the 5 - 10 V range.
The zero point of the measured values is 5 V. At the beginning of the calibration, the amplifiers (for Vr and
Ir) are initialised with minimum amplification. At the end of the calibration procedure, if the adjustment has
been made successfully, the range for the displayed current value is from 1.66 - 3.33 V and the range for the
displayed voltage value is from 6.66 - 8.33 V.
3.2.3. Determining the phase shift: During this step, the transformer-dependent phase shift between Vr and
Ir is measured and corrected. The controller automatically sets the optimum scan times for Vr and Ir.
The actual value display and the actual value output are adjusted to the phase shift. 50% of the set temperature
range of the controller or a signal of ca. 5 V correspond to the optimum value.

7
3.2.4. Determining the reference resistance: (5.7.2.) The reference resistance of the heating conductor
(Rref) is determined in this step. A reference temperature of 0...50 °C must be set in the controller for
calibration. During calibration, the heating conductor must be at the reference temperature to ensure that
regulation is exact. By standardizing the voltage signal (Vr) and the current signal (Ir), the reference resistance
for the different temperature coefficients is always within the same resistance range. If 20 °C has been selected
as the reference temperature, then heating conductor's R20 is directly determined as the reference resistance.
If a heating conductor temperature other than 20 °C has been selected for calibration, then the determined
reference resistance corresponds to the temperature coefficient above or below the value for the R20. The
reference resistance is displayed for one second at calibration step 4 as the actual value and at the actual
value output. With a reference temperature of 20 °C an actual value of
70…80 % of the set temperature range of the controller is displayed or the voltage at the actual value output
is 7 –8 V. The actual value display is between 60 to 100% for the whole reference temperature range of 0 to
50 °C and the voltage at the actual value output is between 6 and 10 V.
3.2.5. Temperature reference time: ( 5.7.3.) The aim of the temperature reference time is to ensure that the
reference resistance can only be determined when the heating conductor has completely cooled down. The
actual value display is counted down during the reference time from 100 % to 0 % of the set temperature range
of the controller. During this reference time, the signal at the actual value output declines from 10 V to 0 V.
Times of 15 or 30 s can be chosen for the temperature reference time.
3.2.6. Checking the reference resistance: The reference resistance is checked after the temperature
reference time is finished. If calibration takes place on a heating conductor that has cooled down still further
during the temperature reference time, the entire calibration will be discarded and the procedure automatically
restarted. Once the reference resistance has been successfully checked, the PIREG-D2calculates the R20
(resistance at 20°C) of the heating conductor from the reference temperature set, the temperature coefficients
selected and the reference resistance (Rbez.) determined.
The reference resistance measured is displayed for one second as the actual value and at the actual value
output. The same value must be shown on the display or the same value must be set at the actual value output
as when the reference resistance was determined ( 3.2.4).
3.2.7. Determining the P-factor: The P-factor of the sealing transformer/heating conductor combination is
determined by heating with a constant correction variable. The heating conductor is either warmed by a
maximum of approx. 60 K or charged for a maximum of 120 network periods with a defined control value.
The total amplification of the control system is calculated from the measurement of the power fed into the
heating conductor and the measurement of the temperature increase of the heating conductor. The P-factor
for the PIREG-D2is calculated from this.
In the case of adverse conditions of the sealing transformer and heating conductor combinations or the public
supply the P-factor of the PIREG-D2can be corrected manually within a range of 30…110 % ( 5.2.5. and
4.9.).
3.2.8. Setting an initializing remanence: Soft switch-on procedure is carried out by setting an initializing
remanence to switch on the sealing transformer without current surge following a calibration. Setting an
initializing remanence takes 80 ms for the El- and 300 ms for toroidal core transformers (with 50 Hz mains
frequency).
3.2.9. Temperature coefficient correction: Differences of temperature coefficients can be corrected using
this function. These result from the dispersion of the metallurgical composition of the heating conductors.
In calibration stage 9, the PIREG-D2gradually heats up the heating conductor in eight temperature increments
or stages. The PIREG-D2compares its actual value temperature with the actual temperature of the heating
conductor, which it receives as a target value or directly as a measured temperature value from the TM6
thermometer.
The size of each increment is a result of the selected temperature range. The first temperature increment is
always 50 °C. The temperature of the eighth temperature increment falls 20% below the final value of the
selected temperature range. The six other temperature increments are equidistant between these points. For
the 300 °C temperature range, this gives the temperatures 50, 77, 104, 131, 159, 186, 213 and 240 °C. For
the 500 °C temperature range, this gives the temperatures 50, 100, 150, 200, 250, 300, 350 and 400 °C.
The actual temperature of the heating conductor must be set as target value in the display unit or reported
back directly to the PIREG-D2as a measured value of the TM6 thermometer via the RS232 interface.
Deviations of up to ±20 % between the calculated actual value temperature and the actual temperature of the
heating conductor can be corrected ( 5.7.4. und 4.9.). The correction process is controlled with the
“Start”/”Heat” option from the Working menu, the Start signal or via the “SSTST” command. The correction
process can also run automatically when the TC correction heating time was correspondingly set.
After a corresponding setting the TC temperature coefficient correction can be saved so that it doesn’t need
to be repeated after a new calibration but only when the heating conductor is replaced ( 5.2.5.).
Performing the temperature coefficient correction:

8
- manual operation: The actual temperature of the heating conductor is reported back as target value to the
PIREG-D2. The next temperature step is switched to with the rising edge of the “Start” signal. After the heating
conductor has reached a uniform temperature the temperature set as the target value is taken
over as the actual temperature of the heating conductor with the falling edge of the “Start” signal. Operation
can also be executed with the “Start”/”Heat” option from the Working menu ( 5.2.).
After heating to the next temperature stage, only accept the temperature once the heating conductor itself
has reached the specified temperature. The displayed actual value and the actual value output will still
indicate the uncorrected actual value temperature of the PIREG-D2.
- manual operation with the TM6 thermometer: The temperature coefficient correction is controlled with the
“Start” signal or the “Start”/”Heat” option as described above. The actual temperature of the heating conductor
is measured with the TM6 thermometer which is connected to the RS232 interface of the PIREG-D2. The
PIREG-D2automatically tries to establish a connection with the TM6 thermometer at the beginning of the
temperature coefficient correction. As soon as a connection to the TM6 thermometer has been established the
measured value is displayed ( 5.2.). Ensure that the same temperature unit is set on the TM6 thermometer
and on the PIREG-D2display unit ( 5.8.).
- automatic temperature coefficient correction: The PIREG-D2must be connected to the TM6 thermometer
and the set value for the TC correction heating time must be greater zero for the automatic temperature
coefficient correction. The heating time is the period until the heating conductor has reached a uniform
temperature at a temperature stage. The heating time is set in the display unit or by the SKTKZ command
(5.7.3. and 4.9.). The PIREG-D2undergoes the automatic temperature coefficient correction independently
and remains at each temperature stage for the preset heating time.
The controller must undergo calibration steps one to eight for each calibration. Step nine is a selectable
calibration function ( 5.7.4.). If an error occurs during the individual calibration steps, the PIREG-D2stops the
calibration process and then restarts the calibration. Calibration is stopped with an error message after attempt
five was not successful ( 3.7.).
After a successful calibration the PIREG-D2returns to the Off-state.
Calibration must be carried out when the heating conductor has reached the determined reference temperature
to ensure that the R20 reference resistance of the heating conductor is calculated correctly. The time required
for a calibration process depends on various factors. The calibration duration is determined by the voltage at
the heating conductor, the current flowing through the conductor, the phase shift from Vr and Ir and the P-
factor of the sealing transformer/heating conductor combination. The controller needs maximum 43 or 58
seconds for one calibration process.
If the calibration process is not successful, e.g. because the P-factor has been determined incorrectly, the
controller makes another four attempts before reporting an error. In this case, the maximum calibration time
can amount to 215 or 290 s, depending of the temperature reference time.
If the calibration mode “new calibration” is chosen, the controller always switches to calibration immediately
after a power-on or after a reset and carries out a new calibration. Calibration can also be started in the Off-
or error state with the signal “Calibration Start” or from the Calibration selection menu of the display unit.
If the calibration mode “Save” is chosen, the controller switches to calibration when in an Off- or error state or
before power-on only when the “Calibration Start” signal is applied. Calibration can also be started in the Off-
or error state from the Calibration selection menu on the display unit ( 5.2.5.). In this type of calibration, the
calibration values are saved in a non-volatile memory and are loaded immediately after a power-on or the
“Reset" signal.
3.2.10. Single-point temperature coefficient correction: With the single-point temperature coefficient
correction the tolerances of the temperature coefficient of the heating conductor can be corrected for just one
operating point. For this operating point the actual temperature of the heating conductor is reported back to

9
the PIREG-D2as target value or directly as measured value of the TM6 thermometer. The singlepoint
temperature coefficient correction is carried out outside the standard calibration and is started from the Off-
state. Single-point temperature coefficient correction has an Off and an On state. After singlepoint temperature
coefficient correction was started, the PIREG-D2is in the Off-state. When the PIREG-D2is in the On-state,
the heating conductor is heated to the temperature which was set as target value in the Off-state.
After heating, only accept the temperature once the heating conductor itself has reached the specified
temperature. The displayed actual value and the actual value output will still indicate the uncorrected actual
value temperature of the PIREG-D2. The single-point temperature coefficient correction finishes upon exiting
the On state. The correction process is controlled with the “Start”/”Heat” option from the Working menu, with
the “Start” signal or via the “SSTST” command. The single-point TC correction can also run automatically when
the TC correction heating time was correspondingly set.
Deviations of up to ±20 % between the calculated actual value temperature and the actual temperature of the
heating conductor can be corrected. Single-point temperature coefficient correction can only be performed if
no standard temperature coefficient correction via eight points ( 3.2.9.) was carried out during calibration.
The single-point temperature coefficient correction is reset at each calibration. After a corresponding setting
the single-point temperature coefficient correction can be saved so that it doesn’t need to be repeated after a
new calibration but only when the heating conductor is replaced ( 5.2.5.).
Performing the single-point temperature coefficient correction:
- manual operation: Single-point temperature coefficient correction is started from the Calibration selection
menu on the display unit ( 5.2.5.) of the PIREG-D2or by the SSTKA command when the PIREG-D2is in the
Off-state. The PIREG-D2retains the temperature set as target value as the temperature of the operating point
as long as a low-signal is applied as “Start” signal. When a high-signal is applied as “Start” signal the
PIREG-D2heats the heating conductor to the temperature of the operating point. Now the actual temperature
of the heating conductor is set as target value. When a low-signal is applied again as "Start” signal, the
PIREG-D2calculates the correction factors for the single-point temperature coefficient correction and saves
these values if "Save" was selected as calibration mode. The single-point temperature coefficient correction
using the “Start”/”Heat” option from the Working menu is controlled as described above.
The status of the single-point temperature coefficient correction is indicated by the corresponding operating
status symbols in the symbol field of the Working menu on the display unit ( 5.2.).
- manual operation with the TM6 thermometer: The single-point temperature coefficient correction is started
and controlled as described above. The actual temperature of the heating conductor is measured with the TM6
thermometer which is connected to the RS232 interface of the PIREG-D2. The PIREG-D2automatically tries
to establish a connection with the TM6 thermometer at the beginning of the singlepoint temperature coefficient
correction. As soon as a connection to the TM6 thermometer has been established the measured value is
displayed ( 5.2.).
- automatic single-point temperature coefficient correction: The PIREG-D2must be connected to the
TM6 thermometer and the set value for the TC correction heating time must be greater zero for the automatic
single-point temperature coefficient correction. The heating time is the period until the heating conductor has
reached a uniform temperature in the On-state of the single-point TC correction. The heating time is set in the
display unit or by the SKTKZ command ( 5.7.3. and 4.9.). Automatic single-point temperature coefficient
correction is started as described above for manual operation. The PIREG-D2undergoes the automatic single-
point temperature coefficient correction independently and remains in the Onstate for the preset heating time.
3.2.11. P-factor correction: The P-factor correction is used for subsequent manual correction of the calibrated
P-factor ( 3.2.7.) in the case of very unfavourable conditions of the sealing transformer/heating conductor
combinations or the public supply. The correction range is 30…110 %.
The P-factor correction is set in the display unit or by the SKPFK command ( 5.2.5. and 4.9.). The P-factor
correction value will not be reset during a calibration as it is system dependent.
3.3. Off-State
The PIREG-D2measures continuously the heating conductor resistance when in the Off-state, determines its
temperature and displays or outputs the temperature as actual value.
For each resistance measurement a positive and negative power line half-wave of the same fixed angle of
current flow (1.8 ms at 50 Hz mains frequency) is applied to the transformer. The time intervals of the
measurements depend on the temperature of the heating conductor. When the heating conductor has reached
a temperature of 20 °C, the measuring interval is 1.5 s. At a temperature of 300 °C, the measuring interval is
only 100 ms.
The heating conductor is heated in the Off-state and dependent on the voltage by the energy introduced when
measuring the resistance.
The controller switches from the Off-state to the On-state as soon as the “Start” signal is applied. When the
“Calibration Start” signal is applied the PIREG-D2returns to calibration and to the off state after the end of a
successful calibration. The PIREG-D2then stays in the Off-state even when the “Calibration Start” signal is
still applied (evaluation of the rising edge). A corresponding control is also possible with the “Start”/”Heat”

10
options from the Working menu ( 5.2.). Single-point temperature coefficient correction can be started from the
Calibration selection menu of the display unit of the PIREG-D2when in the Off-state ( 5.2.5.).
3.4. On-State
In the On-state, the PIREG-D2controls the temperature of the heating conductor in accordance with the target
value. A phase angle controller is used. The controller returns to the Off-state when the “Start” signal is
removed. A corresponding control is also possible with the “Start”/”Heat” options from the Working menu
( 5.2.).
When sequence control is activated the On-state additionally consists of the Start delay and the cooling
phase ( 5.4.).
3.5. Sequence control
The sequence control can be switched on and off (_ 5.4.). If the sequence control is switched off, then a sealing
process with the set target temperature is activated and deactivated after the “Start” signal. If the
sequence control is switched on, a sealing cycle with subsequent start delay, sealing time and cooling time
will be started automatically after the “Start” signal.
3.5.1. Preheating: With “Preheating” the heating element is preheated when the sealing process or a sealing
cycle is paused. Preheating is controlled with the “Preheat” signal. When the “Preheat” signal is
applied the connected PIREG-D2controller adjusts the temperature of the heating conductor to the preset
preheating temperature. The preheating temperature can be set irrespective of the target temperature.
Preheating is also possible when the sequence control is switched off.
3.5.2. Start delay: Start delay is the delay time after the “Start” signal was applied and until sealing time
starts. During the start delay the heating conductor will not be heated by the PIREG-D2. Preheating (if set)
continues to run.
3.5.3. Sealing time: During the sealing time the PIREG-D2adjusts the temperature of the heating conductor
according to the set target value. Depending on the settings the sealing time starts when this sequence
phase is reached or after the actual temperature has exceeded 95% of the target value.
3.5.4. Cooling phase: The sealing time is followed by the cooling phase. Depending on the setting the
heating conductor is to cool down for a set time or to the preset temperature during the cooling phase.
The cooling temperature can either be set as an absolute value or as percentage of the target value.
3.6. Monitoring
3.6.1. Temperature monitoring: Temperature monitoring is a monitoring function which is activated and set
on the display unit (_ 5.5.1.) or by the STUEE command. The actual temperature is monitored during the
sealing process whether it is in the temperature OK-range. If the actual value leaves the temperature OK-
range during the sealing process after the stabilisation time has ended the PIREG-D2will go to error state with
error 83 or 84. The stabilisation time will be restarted if the target value is changed by more than 2 °C.
3.6.2. Monitoring of heating: The heating monitoring is a monitoring function which is activated and set on
the display unit (_ 5.5.2.) or by the SAHUE command. With this function the temperature rise is monitored after
the “Start" signal was applied. If the actual temperature does not reach the temperature OKrange
within the set heating time the PIREG-D2will go to error state with error 85. Preheating monitoring is restarted
if the target value increases by more than 5 °C.
3.6.3. Monitoring of starting: A sealing cycle can be interrupted with the “Start” monitoring function. The
sealing cycle is interrupted when the “Start” signal is no longer applied during the running sealing cycle.
An Emergency Stop function will then be executed. (_ 5.5.)
3.6.4. Monitoring of communication: The monitoring of the communication is an additional monitoring
function for the two interfaces of the PIREG-D2controller and is activated and set with a command (SKOUE)
for each interface individually. This function monitors the communication via the interfaces. If the
communication is interrupted for a longer time than the set downtime, then the PIREG-D2switches to error
state.
3.7. Error state
The error state is indicated on the PIREG-D2only when an error occurs. The controller monitors the line
voltage, the temperature of the heating conductor, the values of the voltage and current measurements at
the heating conductor, the calibration parameters and the monitoring functions.
The Alarm output and the Alarm LED are switched in the error state. The actual value output is also cycled
in some error cases. The voltage at the actual value output then changes every second between the
voltages applicable to the different errors (_ table 1). The error state can only be cancelled by switching off the
power supply, the „Reset“ signal and „Calibration Start“. With errors 10…33 the error state cannot be cancelled
with the “Calibration Start” signal.
In the error state the Error menu can be called from the display unit (_ 5.2.4.). Here, the error number, an error
description and possible corrective actions are displayed.

3.8. Relay functions
The same functions can be set independently for each of the message- and the two control relay outputs.
3.8.1. Temperature function: The relay is actuated if the actual temperature is in the “Temperature ok”
range. A delay during which the actual temperature has stabilized can be set with the stabilization time.
The holding function is an additional function during which the relay remains activated after the sealing
cycle and until start of the following sealing cycle.
3.8.2. Sequence function: This relay function is used to set the conditions when the relay is actuated:
- Active upon “Start” signal: The relay is actuated as soon as the “Start” signal is applied and is released
when the cooling phase has ended.
- Active when temperature is reached: The relay is actuated when the actual temperature has exceeded
95% of the target value and is released when the cooling phase has ended.
- Active during heating phase: The relay is actuated while the sealing time is running off.
- Active during cooling phase: The relay is actuated during the cooling phase.
- Calibration Ok: The relay is not actuated during calibration. It is actuated again after a successful
calibration.
End of calibration is indicated with the “Calibration Ok” function.
3.8.3. Time pulse function: The following switching pulses can be generated with the relays using the
“Time pulse” function:
- Heating phase: The relay is actuated for the set pulse time when sealing time starts, i.e. during heating
of the heating conductor.
- Cooling phase: The relay is actuated for the set pulse time at the start of the cooling phase.
- Pulse end: The relay is actuated for 500 ms at the end of the cooling phase.
3.9. Display functions
3.9.1. Languages: The following languages can be set for the PIREG-D2display unit:
German English French Italian Dutch Russian
3.9.2. Brightness: The brightness of the background lighting is set as a percentage value.
3.9.3. Hold mode: If the “Hold” mode is activated the actual temperature value which was measured at the
end of the sealing process or the sealing time will also displayed. You can select whether the measured
actual value is only displayed for 2 seconds or until the following sealing process or sealing cycle is started.
3.9.4. Cycle counter: The PIREG-D2display unit has a cycle counter (0…9999999) for counting the sealing
cycles. The cycle counter can be reset. In the case of an overflow the counter restarts with zero.
In addition the PIREG-D2display unit has a total cycle counter (0…999999999) which is used as „service life
counter“, and can therefore not be reset.
3.9.5. Saving: With the PIREG-D2display unit settings can be saved and restored. One distinguishes
between parameter sets ( 5.9.1.) and factory settings ( 5.9.2.). The settings for different applications of the
sealing machine are saved using the five parameter sets so that the machine can be adjusted quickly when
the application was changed. One basic setting of the machine can be saved and restored with the factory
settings. In addition the PIREG-D2can be reset to its factory settings.
3.9.6. Releases: The PIREG-D2display unit has three release levels ( 5.8.4.) with which different
userdependent operating levels can be realized. Each release level has its own release number. All release
numbers are factory-set to “0000”. All release levels are thus activated after the controller was switched on
so that the controller can be set. After switching off or resetting the controller, all levels are locked, for which
the release number is not "0000". To unlock a release level permanently, the release number of this release
level should be "0000". An unlocked release level can be locked again by entering the release number
"0000", without having to switch off the controller.
The following settings are assigned to the individual release levels.
- Level 0: Control via the inputs and buttons of the display unit (unprotected).
- Level 1: - Setting of level 0
- Target value
- Sealing time and cooling time
- Reference temperature for calibration
- Reading parameter sets 1…5
- Level 2: - Setting of level 1
- All controller settings
(settings of the TC temperature, time, calibration and target value)
- Saving parameter sets 1…5
- Level 3: - Setting of level 2
- All settings of the PIREG-D2

13
3.9.7. Temperature unit: With the PIREG-D2display unit the temperature values can be indicated in [°C]
or [°F] ( 5.8.). The temperature unit is only used for display of the temperature values. The display unit
continues to operate internally with the unit [°C] even when [°F] is displayed which results in temperature
leaps of 2 °F when the unit [°F] is set as temperature value.
When working with the TM6 thermometer the same temperature unit must be set on the thermometer and
on the PIREG-D2display unit.
4. Operation
4.1. Keys
The following five keys are used for operating the PIREG-D2display unit:
4.1.1. Cursor: The cursor is moved to the possible setting items using the arrow keys in the display.
There are numerical values which can be set, options which can be selected and menu items for calling
another menu. An empty triangle is used as symbol for the cursor. The cursor remains on the menu
item which was selected last after the menu was changed.
4.1.2. Setting numerical values: Move the cursor to the numerical value to be set and confirm with the
Ok button. As soon as the value is changed using the and buttons the value starts flashing at a frequency
of 1 Hz indicating that the value was changed. The value is accepted after the Ok button was
pressed and stops flashing. Press the key to cancel the changes and to restore the original value.
If the and buttons are pressed for more than 1 second the numerical value starts to run at a rate of
change of 10 dig/sec.. If the button is pressed more than 3 seconds the rate of change increases to 100
dig/sec..
4.1.3. Selecting functions: Move the cursor to the item to be selected. Press the Ok button to select the
item. A filled triangle is used as selection cursor. If the cursor and the selection cursor are on the same
function, the display changes between the selection cursor and the cursor at a frequency of 1Hz.
4.1.4. Acceptance of the settings: The set numerical values are accepted by pressing the Ok button. If
the setting is not accepted within 3 seconds after it was changed with the Ok button, then the setting will
be discarded and the old value will be further used.
The numerical values can also be accepted automatically, i.e. the setting will be accepted if it was not
changed for more than 3 seconds. The automatic acceptance is activated and deactivated in the Operating
menu ( 5.8.3.).
4.1.5. Menu change: Move the cursor to the menu item if you want to change the menu. If the menu
item is also an option, you should use the button to change the menu. Press the Ok button if it is a
mere menu item. Exit the menu with the button .
Switch to the last changed setting in a menu by pressing the +simultaneously in the Working menu.
4.1.6. Menu return: If no changes were made, the program will return from all menus to the Working
menu after 20 seconds at the latest. Press the key combination +to jump to the position in the menu
where the program returned to the Working menu. The menu return can be activated and deactivated in
the Operating menu ( 5.8.3.).
4.1.7. Locking: A locking which prevents unintentional changes of the settings is provided which can be
activated and deactivated by pressing the key combination + + Ok . First, however, the locking must be
activated in the Operating menu ( 5.8.3.).
4.1.8. Execution prevention: If a setting or menu change is not possible, the cursor changes to a diagonal
cross for one second to indicate this status.
Please note: Most settings cannot be changed during calibration process and in ON-condition.
4.2. LEDs
4.2.1. Power: The green Power LED indicates that the PIREG-D2controller is connected to the line voltage.
4.2.2. Heat: The yellow LED “Heat” indicates that a sealing cycle is executed if the sequence control is
switched on. If the sequence control is switched off, this LED only signalizes the sealing process itself.
4.2.4. Alarm: The red LED “Alarm” indicates that an error is present and that the PIREG-D2controller is in
an error state. The error is shown in plain text in the Error menu on the display unit ( 5.2.4.).
4.3. Inputs
4.3.1. Start inputs: The PIREG has two Start inputs: one Start input (X3) which is controlled by an external
voltage, and the Start contact input (X7) which is controlled when the input is connected to AGND (X2) for
example with a switch.
A sealing process or a sealing cycle is started by applying the high-signal to the Start input (X3) or
connecting the Start contact input (X7) with AGND (X2). If the sequence control is switched on and the
“Start” monitoring function is deactivated, a sealing cycle will only be started with rising edge.

14
If standard TC correction via eight points was selected the correction process is also controlled by the
Start inputs for manual operation. The single-point TC correction is also controlled by the Start inputs.
4.3.2. Preheat inputs: The PIREG has two Preheat inputs: one Preheat input (X22) which is controlled by an
external voltage, and the Preheat contact input (X19) which is controlled when the input is connected
to AGND (X2) for example with a switch.
If a high-signal is applied to the Preheat input (X22) in the pause between two sealing processes or sealing
cycles or the Preheat contact input (X19) is connected to AGND (X2), the PIREG-D2will regulate the
temperature of the heating conductor to the set preheating temperature (_ 5.4.1.).
4.3.3. Calibration Start input: When a high-signal is applied to the Calibration Start input (X25) in the
Off- or error state the PIREG-D2changes in the calibration state. Normally the controller is adapted to the
sealing transformer and heating conductor combination. During calibration of the controller the signal can
be switched back to Low.
4.3.4. Reset input: When a high-signal is applied to the Reset input (X26) the PIREG-D2is reset to the
status after power-on in case of a malfunction. This is possible without switching the line voltage off.
4.3.5. Target value input: Beside setting the target value on the PIREG-D2display unit, the target temperature
can also be set on the target value input (X23). The target value is set with an analogue voltage.
The option for setting the target temperature is selected on the display unit (_ 5.7.5.) or by a command.
- Internal: The target value is set on the PIREG-D2display unit (_ 5.2.).
- Target value U: The temperature target value is set with an analogue voltage. The voltage range of the
target value is 0 - 10 V. The selected temperature range applies to the maximum target voltage i.e. 10 V at the
target value input correspond to 300 °C if the selected temperature range is 300 °C.
- Target value R: The temperature target value is set with a potentiometer. For the potentiometer the
wiper is connected to the target value input (X23), the CW connection to the actual value output (X24) and the
CCW connection to the GND connection (X20). The actual value output then works as reference voltage
source with an output voltage of 10 V. Pay attention to the correct phase sequence when connecting the
potentiometer. The voltage at the target value input should increase for clockwise rotation (CW) on the
potentiometer. The selected temperature range is adjusted to the target value voltage as described above.
4.4. Outputs
4.4.1. Actual value output: The actual value output (X24) supplies a voltage in the range 0 - 10 V,
proportional to the temperature of the heating conductor. The voltage range refers to the selected
temperature range, i.e. 10 V at the actual value output correspond to 300 °C if the selected temperature
range is 300 °C. The actual value output can supply a maximum current of 5 mA.
When the target value input is used with a potentiometer (setting “target value R”) the actual value output
operates as a constant voltage source with an output voltage of 10 V.
4.4.2. Message relay output: The message relay output 1 (X21) has an NO contact which operates against
the GND connection (X20). It can be set whether the contact is open or closed when the relay is actuated.
The switching capacity of the relay contact is only designed for message functions. The relay contact was
set at the factory to be closed when the relay is actuated.
4.4.3. Control relay outputs: The control relay outputs 1 (X16/X17/X18) and 2 (X27/X28/X29) provide a
change-over contact. The switching capacity is only designed for control functions.
4.4.4. Alarm output: The alarm output (X5/X6) is a relay switching contact. It can be set whether the alarm
output is opened or closed in the case of a fault. The factory setting of the relay contact is “closed” when a
fault occurs.
4.4.5. ELR output: The ELR output (X1/X2) controls an external solid-state relay which is used as actuator
instead of the internal actuator of the controller. Combinations of heating conductor and sealing transformer
with capacities exceeding the permissible capacity of the internal actuator can be switched with the external
solid-state relay.
4.5. Interfaces
We will provide you with the detailed interface description of the control system with integrated PIREG-D2
resistance temperature controller for packaging machines if required.
