This RESISTRON temperature controller is
manufactured according to DIN EN 61010-1. In the
course of its manufacture it passed through quality
assurance, whereby it was subjected to extensive
inspections and tests.
It left the factory in perfect condition.
The recommendations and warning notes contained in
these operating instructions must be complied with, in
order to guarantee safe operation.
The device can be operated within the limits indicated
in the "Technical Data" without impairing its operational
safety. Installation and maintenance may only be
performed by technically trained, skilled persons who
are familiar with the associated risks and warranty
provisions.
1.1Use
RESISTRON temperature controllers may only be used
for heating and temperature control of heatsealing
bands which are expressly suitable for them, and
providing the regulations, notes and warnings
contained in these instructions are complied with.
In case of non-compliance or use contrary to
!
the intended purpose, there is a risk that
safety will be impaired or that the heatsealing band,
electrical wiring, transformer etc. will overheat.
Ensuring such compliance is the personal
responsibility of the user.
The RESISTRON temperature controller must be set
and coded according to the temperature coefficient of
the heatsealing band.
The use of incorrect alloys with a too low
!
temperature coefficient and incorrect coding
of the RESISTRON temperature controller lead to
uncontrolled heating and ultimately to burn-out of
the heatsealing band!
The heatsealing bands that were originally supplied
must be identified by detail specification, part number
or some other means that will assure that replacement
bands are identical.
1.3Impulse transformer
A suitable impulse transformer is necessary to ensure
that the control loop functions perfectly. This
transformer must be designed according to VDE 0570/
EN 61558 (isolating transformer with reinforced
insulation) and have a one section bobbin. When the
impulse transformer is installed, suitable shock
protection must be provided in accordance with the
national installation regulations for electrical
equipment. In addition, water, cleaning solutions and
conductive fluids must be prevented from seeping into
the transformer.
Incorrect installation of the impulse
!
transformer impairs electrical safety.
1.2Heatsealing band
A basic prerequisite for reliable and safe operation of
the system is the use of suitable heatsealing bands.
The resistance of the heatsealing band which
!
is used must have a positive minimum
temperature coefficient in order to guarantee
trouble-free operation of the RESISTRON
temperature controller.
The temperature coefficient must be specified as
follows:
TCR 104–×10 K
≥
e.g.Alloy-20:TCR = 1100 ppm/K
NOREX:TCR = 3500 ppm/K

1.4Current transformer PEX-W2/-W3
The current transformer supplied with the RESISTRON
temperature controller is an integral part of the control
system.
Only the original ROPEX PEX-W2 or PEX-W3
!
current transformer may be used. Other
transformers may cause the equipment to
malfunction.
The current transformer may only be operated if it is
connected to the RESISTRON temperature controller
correctly (see section 9, "Startup and operation"). The
relevant safety instructions contained in section 8.3,
"Power supply", must be obeyed. External monitoring
modules can be used in order to additionally increase
Application
operating safety. They are not included in the scope of
supply of the standard control system and are
described in a separate document.
1.5Line filter
The use of an original ROPEX line filter is mandatory in
order to comply with the standards and provisions
mentioned in section 1.7 "Standards / CE marking" on
page 4. This device must be installed and connected
according to the instructions contained in section 8.3,
"Power supply" as well as the separate documentation
enclosed with the line filter.
1.6Warranty provisions
The statutory provisions for warranties apply for a
period of 12 months following the delivery date.
All devices are tested and calibrated in the factory.
Devices that have been damaged due to faulty
connections, dropping, electrical overloading, natural
wear, incorrect or negligent handling, chemical
influences or mechanical overloading as well as
devices that have been modified, relabeled or
otherwise altered by the customer, for example in an
attempt to repair them or install additional components,
are excluded from the warranty.
Warranty claims must be examined in the factory and
approved by ROPEX.
1.7Standards / CE marking
The controller described here complies with the
following standards, provisions and directives:
DIN EN 61010-1
(VDE 0411-1)

2Application
This RESISTRON temperature controller is an integral
part of the "series 400", the outstanding feature of
which is its microprocessor technology. All
RESISTRON temperature controllers are used to
control the temperature of heating elements
(heatsealing bands, beaded bands, cutting wires,
heatsealing blades, solder elements etc.), as required
in a variety of heatsealing processes.
Page 4RES-407
The controller is most commonly used for impulseheatsealing PE and PP films in:
•Vertical and horizontal f/f/s machines
•Pouch, filling and sealing machines
•Film wrapping machines
•Pouch-making machines
•Group packaging machines
•L-sealers
Principle of operation
•etc.
The use of RESISTRON temperature controllers
results in:
•Repeatable quality of the heatseals under any
conditions
3Principle of operation
The resistance of the heatsealing band, which is
temperature-sensitive, is monitored 50x per second
(60x at 60Hz) by measuring the current and voltage.
The temperature calculated with the help of these
measurements is displayed and compared with the set
point.
The primary voltage of the impulse transformer is
adjusted by phase-angle control if the measured values
deviate from the set point. The resulting change in the
current through the heatsealing band leads to a change
in the band temperature and thus also its resistance.
This change is measured and evaluated by the
RESISTRON temperature controller.
The control loop is closed: ACTUAL temperature = SET
temperature. Even minute thermal loads on the
heatsealing band are detected and can be corrected
quickly and precisely.
The thermoelectric control loop which is formed has a
highly dynamic response because purely electrical
variables are measured at a high sampling rate. A very
wide secondary current range can be controlled with
only minimal power loss - a considerable advantage because power is controlled on the primary side of the
•Increased machine capacity
•Extended life of the heatsealing bands and teflon
coatings
•Simple operation and control of the sealing process
transformer. This allows optimum adaptation to the
load and to the required dynamic range despite the
exceptionally compact dimensions of the controller.
PLEASE NOTE!
RESISTRON temperature controller play a significant
role in enhancing the performance of modern
machines. However, the full benefit can only be
obtained from the advanced technology offered by this
control system if all the system components, in other
words the heatsealing band, the impulse transformer,
the wiring, the timing signals and the controller itself,
are compatible with one another.
We will be pleased to
contribute our many
years of experience
towards optimizing your
heatsealing system.

4Description of the controller
Description of the controller
The microprocessor technology endows the
RESISTRON temperature controller RES-407 with
previously unattainable capabilities:
•Very simple operation thanks to AUTOCAL, the
automatic zero calibration function.
•Good dynamic response of the control system
thanks to AUTOTUNE, which adapts automatically
to the controlled system.
•High precision thanks to further improved control
accuracy and linearization of the heatsealing band
characteristic.
•High flexibility: The AUTORANGE function (as of
April 2005) covers a secondary voltage range from
0.4V to 120 V and a current range from 30 A to
500A.
•Automatic adjustment to the line frequency in the
range from 47 Hz to 63Hz.
•Increased protection against dangerous conditions,
such as overheating of the heatsealing band.
The electrically isolated analog interfaces for the
temperature set point and the actual temperature
(0-10VDC) allow the temperature to be set either
directly on the machine PLC or by means of an external
potentiometer (PD-x).
Similarly, the real heatsealing band temperature can be
visualized either on the display of the machine PLC or
on an external temperature meter (ATR-x).
The RESISTRON temperature controller RES-407
features an integrated fault diagnosis function, which
tests both the external system (heatsealing band,
wiring etc.) and the internal electronics and outputs a
selective error message in case of a fault.
To increase operational safety and interference
immunity, all 24VDC logic signals are electrically
isolated from the controller and the heating circuit.
Coding switches on the temperature controller itself
can be used to adapt to different heatsealing band
alloys (Alloy A20, NOREX etc.) and set the required
temperature range (0...300 °C, 0...500°C etc.) on all
controllers manufactured as of June 2003.
An external 24VDC auxiliary voltage is required to
supply the isolating amplifiers and optocouplers. The
compact design of the RESISTRON temperature
controller RES-407 and the plug-in connections make
this controller easy to install.
5Accessories and modifications

Additional terminal for "Temperature reached" signal.
This output signal is activated when the ACTUAL

the SET heatsealing temperature. It can be used to
monitor the process, for example, or to control the
closure of the heatsealing bars.

MOD 46 (as of April 2005)
Additional terminal for "Temperature OK" signal. If this
modification is installed, the RES-407 checks whether
the ACTUAL temperature is within a settable tolerance
band ("OK" window) on either side of the SET
temperature. The lower () and upper
() tolerance band limits are configured in the
∆ϑ
upper
factory to -10 K and +10 K. These values can be set
independently of one another in the ROPEX
visualization software (ª section 10.11 "Diagnostic
interface/visualization software (as of April 2005)" on
page 31).
If the actual temperature is inside the specified
tolerance band when the "START" signal is activated,
the output signal is activated as well (see graph below):

Actual value
If the actual temperature leaves the tolerance band, the
output signal is deactivated again. The output signal
then remains deactivated, even if the actual temperature subsequently returns to the tolerance band.
It is thus possible to check - as part of the monitoring
concept, for instance - whether the output signal is still
active at the end of the heatsealing process, in other
words whether the actual temperature has remained
within the defined tolerance band throughout the entire
process.
The output signal is not deactivated again until the next
"START" signal is activated or until an alarm is
signaled.
MOD 46 ("Temperature OK" signal) cannot be

used in combination with MOD 40

corrected after a few heating cycles (ª section 9.3.2
"Burning in the heatsealing band" on page 21).
One very important design feature is the copper or
silver-plating of the heatsealing band ends. Cold ends
allow the temperature to be controlled accurately and
increase the life of the teflon coating and the
heatsealing band.
An overheated or burned-out heatsealing
!
band must no longer be used because the
TCR has been altered irreversibly.
9.3.2Burning in the heatsealing band
9.3Heatsealing band
9.3.1General
The heatsealing band is a key component in the control
loop, since it is both a heating element and a sensor.
The geometry of the heatsealing band is too complex to
be discussed at length here. We shall therefore only
refer to a few of the most important physical and
electrical properties:
The measuring principle applied for this system
necessitates a heatsealing band alloy with a suitable
temperature coefficient TCR, i.e. one whose resistance
increases as the temperature rises.
Too low a TCR leads to oscillation or uncontrolled
heating.
When heatsealing bands with a higher TCR are used,
the controller must be calibrated for this.
The first time the heatsealing band is heated to
approximately 200…250°C, the standard alloy
undergoes a once-only resistance change (burn-in
effect). The cold resistance of the heatsealing band is
reduced by approximately 2…3 %. However, this at first
glance slight resistance change results in a zero point
error of 20…30°C. The zero point must therefore be
If a new heatsealing band has been used, the zero
point is first of all calibrated while the band is still cold
by activating the "AUTOCAL" function on the controller.
When the "AUTOCAL" function has finished, the
controller outputs a voltage equivalent to a temperature
of 20°C at the actual value output. Adjust the set point
to approximately 250 °C and activate the "START"
signal to heat for approximately 1 second. After
recooling, the controller usually outputs an actual value
of less than 20 °C. Repeat the "AUTOCAL" function.
The heatsealing band has now been burned in and the
change in the alloy stabilized.
The burn-in effect described here does not occur if the
heatsealing band has already been thermally
pretreated by the manufacturer.
9.3.3Replacing the heatsealing band
All power supply leads must be disconnected from the
RESISTRON temperature controller in order to replace
the heatsealing band.
The heatsealing band must be replaced in
!
accordance with the instructions provided by
the manufacturer.
RES-407Page 21
Startup and operation
Each time the heatsealing band is replaced, the zero
point must be calibrated with the AUTOCAL function
while the band is still cold, in order to compensate
production-related resistance tolerances. The burn-in
procedure described above should be performed for all
new heatsealing bands.
9.4Startup procedure
Please also refer to section 1 "Safety and warning
notes" on page 3 and section 2 "Application" on
page 4.
Installation and startup may only be
!
performed by technically trained, skilled
persons who are familiar with the associated risks
and warranty provisions.
9.4.1Initial startup
Prerequisites: The controller must be correctly installed
and connected (ª section 8 "Installation" on page 12).
Proceed as follows to start up the controller for the first
time:
1. Switch off the line voltage and verify that all circuits
are deenergized.
2. The supply voltage specified on the nameplate of
the controller must be identical to the line voltage
that is present in the plant or machine. The line
frequency is automatically detected by the
temperature controller in the range from 47 to 63 Hz.
3. In the case of controllers manufactured up to March
2005, the settings of the DIP switches on the
controller are indicated in the ROPEX Application
Report and depend on the heatsealing band that is
used (section 9.2 "Controller configuration" on
page 19).
4. Make sure that no START signal is present.
5. Apply the auxiliary voltage (24VDC).
6. Switch on the line voltage.
7. When the voltage is switched on, the yellow
"AUTOCAL" LED lights up for approximately
0.3 seconds to indicate that the controller is being
powered up correctly.
As of SW-Revision 106:
!
If the red "ALARM" LED lights up for 0.3s in
addition to the yellow "AUTOCAL" LED when the
voltage is switched on, the configuration of this
controller has been changed in the visualization
software (ªªªª section 10.11 "Diagnostic interface/
visualization software (as of April 2005)" on
page 31). In order to avoid malfunctions, please
check the controller configuration before
continuing the startup procedure.
8. One of the following states then appears:
"ALARM"
LED
OFFShort pulses
BLINKS fast

9. Activate the AUTOCAL function while the
heatsealing band is still cold (terminals 5+14). The
yellow "AUTOCAL" LED lights up for the duration of
the calibration process (approx. 10…15s). A
voltage of app. 0 V appears at the same time at the
actual value output (terminals 17+14). If an ATR-x is
connected, it indicates 0…3°C.
When the zero point has been calibrated, the
"AUTOCAL" LED goes out and a voltage of 0.66 V
(300°C range) or 0.4 V (500°C range) appears at
the actual value output instead. If an ATR-x is
connected, it must be set to "Z".
If the zero point has not been calibrated
successfully, the red "ALARM" LED blinks slowly
(1Hz). In this case the controller configuration is
incorrect (ª section 9.2 "Controller configuration"
on page 19 and ROPEX Application Report).
Repeat the calibration after the controller has been
configured correctly.
10.When the zero point has been calibrated
successfully, set a defined temperature at the set
point input (terminal 16) and apply the "START"
signal (HEAT). The "HEAT" LED then lights up. The
heating and control process can be observed at the
actual value output:

An indicating instrument can be connected to this

The characteristics of the ROPEX ATR-x temperature

suited to this application and this instrument should
therefore always be used (ª section 5 "Accessories
and modifications" on page 6).
It not only facilitates SET-ACTUAL comparisons, but
also enables other criteria such as the heating rate, set
point reached within the specified time, cooling of the
heatsealing band etc. to be evaluated.

10.4Automatic zero calibration
(AUTOCAL)
Owing to the automatic zero calibration (AUTOCAL)
function, there is no need to adjust the zero point manually on the controller. This function matches the controller to the current and voltage signals that are present in the system. The zero point is calibrated in the
factory to the initial temperature (ambient temperature,
20°C).
Variable initial temperature:
On controllers manufactured as of April 2005, the initial
temperature for the "AUTOCAL" function can be set in
the 0…+40°C range in the visualization software
(ª section 10.11 "Diagnostic interface/visualization
software (as of April 2005)" on page 31). This setting is
remembered if the controller is switched off and then on
again.
As of SW Revision 107, the "External calibration temperature" setting can also be selected in the visualization software. The initial temperature for this setting can
be specified in the +3…+40°C range via the analog
input (terminals 16+14) (ª section 10.2 "Temperature
setting (set point selection)" on page 25). The value
selected at the analog input must be present when the
"AUTOCAL" function is activated.
If the specified temperature is too high (greater than
40°C) or if the selected value varies, an error message
appears (error codes 115 and 116; ª section 10.13
"Error messages" on page 32).
The "AUTOCAL" function is activated by means of a
24VDC pulse at terminals 5+14.

Reasons for disabled "AUTOCAL" function:
1. The "AUTOCAL" function cannot be activated until
10seconds after the controller is switched on. If you
attempt to activate it sooner, it will not work.
2. The "AUTOCAL" function cannot be not activated if
the heatsealing band cools down at a rate of more
than 0.1K/ s. If the control signal is activated, the
function is executed automatically providing the
cooling rate has fallen below the above-mentioned
value.

4. If the "RESET" signal (24VDC) is active, the
"AUTOCAL" function is not executed.
5. The "AUTOCAL" function cannot be activated if
error codes 101…103, 201…203, 801 or 9xx (up to
March 2005: error codes 1…3, 5…7) occur on

correctly - at least once - after starting up, the
"AUTOCAL" function cannot be activated with error
codes 201…203, 801 or 9xx (up to March 2005:
error codes 5…7).
10.5"START" signal (HEAT)
When the "START" signal is activated, the controllerinternal set/actual comparison is enabled and the
heatsealing band is heated up to the SET temperature.
It remains at this temperature until the signal is
deactivated again.
The "HEAT" LED on the front panel of the RES-407 is
lit continuously for the duration of the heating phase.
The "START" signal is activated by means of a 24VDC
signal at terminals 6+14.
The set point that is selected for the heatsealing
temperature must be greater than 40°C. If not, the
heatsealing band will not be heated up.
The alarm output is switched if the "START" signal is
activated while an error message is indicating error
codes 104…106, 111…114, 211, 302 or 303 (up to
March 2005: error codes 8…12) (ª section 10.13
"Error messages" on page 32). The heatsealing band is
no longer heated up.
10.6"RESET" signal
The RESISTRON temperature controller RES-407 can
be reset by means of an external "RESET" signal at
terminals 7+14). As a result:
•A heatsealing cycle is aborted if one is in progress
•No more measuring impulses are generated
•An error message is reset if one is present
(Note: The error message is not reset until the
"RESET" signal is deactivated)

Controller functions
The controller performs an internal
!
initialization run lasting approximately
500ms after the "RESET" signal is deactivated. The
next heatsealing process cannot be started until it
has finished.
If a contactor Kb is used to deactivate the
!
control loop (ªªªª section 8.3 "Power supply"
on page 14), it must be energized again 50ms at the
latest after the "RESET" signal is deactivated. If it is
energized too late, an error message will be output
by the controller.
10.7Measuring impulse duration
(as of April 2005)
The length of the measuring impulses generated by the
controller can be set with the parameter. It may be
necessary to set a measuring impulse that is longer
than the default 1.7 ms for certain applications
(ª ROPEX Application Report).
This parameter can only be set by means of
!
the ROPEX visualization software
(ª section 10.11 "Diagnostic interface/
visualization software (as of April 2005)" on
page 31).
If the interval between the two "AUTOCAL"
functions is longer than 2.0 s, "AUTOCAL" is
executed normally again the second time.

(as of April 2005)
It may be necessary to compensate the phase angle

Application Report). The "AUTOCOMP" function is
provided for this purpose. The following settings are
possible:
1. „OFF" (Factory settings)
The „AUTOCOMP“ function is deactivated.
2. „ON“
The „AUTOCOMP“ function is executed whenever
the "AUTOCAL" function (ª section 10.4
"Automatic zero calibration (AUTOCAL)" on
page 27) is run twice in quick succession. The
interval between the end of the first "AUTOCAL"
function and the start of the second "AUTOCAL"
must be shorter than 2.0 s. The second "AUTOCAL"
function only takes around 2.0s and incorporates
the "AUTOCOMP" function.

10.9Temperature diagnosis
(as of April 2005)
An additional temperature diagnosis can be activated in
the ROPEX visualization software (ª section 10.11
"Diagnostic interface/visualization software (as of April
2005)" on page 31). The RES-407 checks whether the
ACTUAL temperature is within a settable tolerance
band ("OK" window) on either side of the SET
Time
Alarm
307
If the temperature diagnosis is not activated by the time
the "START" signal is deactivated (i.e. if the ACTUAL
temperature does not exceed the upper or lower
tolerance band limit), the corresponding error code
(309, 310) is indicated and the alarm output is
switched.
An additional delay time (0…9.9 s) can be set in the
ROPEX visualization software. The first time the lower
tolerance band limit is exceeded, the temperature
diagnosis is not activated until the parameterized delay
time has elapsed. The temperature diagnosis function
can thus be explicitly deactivated, e.g. if the
temperature drops temporarily owing to the closure of
the sealing jaws.
The values that can be set in the ROPEX
!
visualization software for the upper and
lower tolerance band are identical to those for the
"Temperature OK" signal (MOD 46).

10.10Heatup timeout
(as of April 2005)
An additional heatup timeout can be activated in the
ROPEX visualization software (ª section 10.11
"Diagnostic interface/visualization software (as of April
2005)" on page 31).
This timeout starts when the START signal is activated.
The RES-407 then monitors the time required for the
ACTUAL temperature to reach 95% of the SET
temperature. If this time is longer than the
parameterized time, the corresponding error code
(304) is indicated and the alarm output is switched
(ª section 10.13 "Error messages" on page 32).

Only a ROPEX comunication interface is

allowed to be connected to the diagnostic
interface. Connecting another device (e.g. a
telephone cable) could result in malfunctions or
damage to the controller.
The ROPEX visualization software is described in a
separate document.
10.12System monitoring/alarm output
To increase operating safety and to avoid faulty
heatsealing, this controller incorporates special
hardware and software features that facilitate fault
diagnosis and selective error messages. Both the
external wiring and the internal system are monitored.
These features assist the operator in identifying the
cause of abnormal operations.
A system fault is reported or differentiated by means of
the following indications:
A.)Red "ALARM" LED on the controller with
three states:
Timeout
1. Blinks fast (4 Hz):
The "AUTOCAL" function should be executed (error

codes 104…106, 211, 302, 303; up to March 2005:
error codes 8+9).
2. Blinks slowly (1 Hz):
The system configuration is incorrect and the zero
calibration ("AUTOCAL" function) was unsuccessful
10.11Diagnostic interface/visualization
software (as of April 2005)
(ª section 9.2 "Controller configuration" on
page 19). It corresponds to error codes 110…114
(up to March 2005: error codes 10…12).
An interface with a 6-pole Western socket is provided
for systemdiagnostics and process visualization. This
interface allows a data connection to be set up to the
ROPEX visualization software using the ROPEX
communication interface CI-USB-1.
3. Lit continuously:
A fault is preventing the controller from being started
(error codes 101…103, 107, 108, 201…203, 307,
308, 801, 9xx; up to March 2005: error codes 1…7).
Also in instances 1 and 2 if the "START" signal is
activated simultaneously.
As a rule, it refers to an external wiring fault.

This logic output is set in the factory as follows:
•LOW (OPEN) in operating states A.1) and A.2), but
high (closed) if a "START" signal is activated in one
of these states.
•HIGH (CLOSED) in operating state A.3)
RES-407Page 31
Controller functions
If the alarm relay is configured opposite to the factory
setting (ª section 9.2.3 "Configuration of the alarm
output (as of April 2005)" on page 21), these states are
reversed.
C.)Error code output via the 0 to 10 V DC
actual value output (terminals 17+14):
Since a temperature indication is no longer necessary
if a fault occurs, the actual value output is used to
display error messages in the event of an alarm.
13 voltage levels (up to March 2005: 12 voltage levels)
are offered for this purpose in the 0…10VDC range,
each of which is assigned an error code
(ª section 10.13 "Error messages" on page 32).
If a state that requires "AUTOCAL" occurs - or if the
controller configuration is not correct - (error codes
104…106, 111…114, 211, 302, 303; up to March 2005:
error codes 8…12), the actual value output jumps back
and forth at 1 Hz between the voltage value which
corresponds to this error and the end of the scale (10 V
DC, i.e. 300 °C or 500 °C). If the "START" signal is
activated in one of these states, the voltage value does
not change any more.
Selective fault detection and indication can thus be
implemented simply and inexpensively using the
analog input of a PLC with a corresponding error
message (ª section 10.13 "Error messages" on
page 32).
An alarm can only be reset by applying a
!
"RESET" signal or by switching the
controller off and then on again.
If an error message is reset using the
!
"RESET" signal, the "RESET" signal must be
deactivated first.
Invalid error messages may appear when the
!
controller is switched off owing to the
undefined operating state. This must be taken into
account when they are evaluated by the higherlevel controller (e.g. a PLC) in order to avoid false
alarms.
10.13Error messages
The table below shows how the analog voltage values
that appear at the actual value output correspond to the
faults that have occurred. It also describes each fault
and the required corrective action.
The error messages are listed in two separate tables for
controllers "up to March 2005" and "as of April 2005".
The block diagram in section 10.14 "Fault areas and
causes" on page 37 permits each fault to be cleared
quickly and efficiently.
13 voltage levels for fault diagnostics appear at the
actual value output of all controllers manufactured as of
April 2005. The error messages are differentiated even
more finely in the controller. The error codes described
below can be displayed with the ROPEX visualization
software (ª section 10.11 "Diagnostic interface/
visualization software (as of April 2005)" on page 31) to
facilitate troubleshooting.
If the actual value output is evaluated in order
!
to identify an error message - in the higherlevel controller, for instance - the tolerance window
must be adjusted to prevent it from being
incorrectly interpreted. Please note the tolerances
of the actual value output (ªªªª section 6 "Technical
data" on page 10).
