1.4 Hazards
Tilting
The risks for tilting increases when the platform is in el-
evated position do not transport the mobile dryer unless
its platform is lowered completely. Small adjustments in
length and sideways can be made in elevated positions
to get the green lights from the distance indicators. All
movements of the IRT Siemens Leading Edge Protection
Dryer are to be made with help of the four handle bars
one at each corner at the base. No adjustments or move-
ment of the dryer are to be made by applying force to
the scissor/lifting part of the mobile dryer or frame with
the IR heaters mounted on the lifting platform.
1. Safety instructions
1.1 Operator´s duty of care
The IRT Siemens Leading Edge Protection Dryer is
designed and built after a hazard assessment was con-
sidered and following careful selection of the required
harmonized standards as well as additional technical
specifications. It corresponds to the current state of tech-
nology and guarantees the highest safety level.
However, this safety level can only be reached during
practical operation, when all the required measures have
been implemented. Due diligence is required on the
part of the platform operator, to plan these measures
and ensure their implementation.
In particular, the operator must always ensure that:
• the dryer is only used for the intended purpose.
• the dryer is only to be used in a fully functional and
fault-free state and it is to be checked regularly for
operational functionality with special attention paid
to the safety equipment.
• persons are prevented from entering the hazardous
area (space under the IR platform). Maintenance
work is excepted.
• the operating instructions must always be fully leg-
ible and available at the dryer operational site.
• the dryer is only used by individuals who have read
and understood the operating manual.
• only adequately qualified and authorized personnel
are allowed to operate, maintain or repair the dryer.
• none of the safety and warning labels on the dryer are
to be removed and all of them must always be legible.
• the personnel are to be regularly instructed in all
relevant questions regarding work safety, environ-
mental protection and the operating manual and
especially the safety instructions contained therein.
• the heater platform must be lowered into its start
position after you have finished working with it.
1.2 Task of the operator
Certain measures are included in the Industrial Safety
Regulations for operators using working equipment in
hazardous areas.
The operator must conduct a risk assessment of the area
in which the working equipment (working platform) is
to be deployed. The hazardous situations that can be
caused when using the working equipment in conjunc-
tion with the working materials and the working environ-
ment should be recognized and addressed.
The operator must implement the required measures
and select the equipment which is appropriate for the
given workplace conditions and which, if used for its
intended purpose, offer the necessary protection as
regards health and safety.
The operator must apply national directives and stan-
dards when conducting the risk assessment and choos-
ing the appropriate equipment.
1.3 Basic safety measures
The IRT Siemens Leading Edge Protection Dryer must not
be exposed to paint fog, sanding dust or solvents, due to

4196349 rev 1
EN
Fire and explosion.
Do not store, prepare or use solvent-containing materials
within a 5 m/16 feet radius of the mobile dryer. Flam-
mable materials should not be placed close to a drying
device in use.
If you have a distance less than 60 cm/2 feet to the ob-
ject the temperature might raise quickly and the risk for
fire increases. Never direct the cassette towards highly
combustible materials.
Electrical equipment
The dryer is operated with high electrical voltage, which
can be highly dangerous.
Before accessing live parts, remove the main connector
from the wall socket. Only professional electricians may
have direct access to the electrical components.
If the supply cord is damaged, it must be replaced by
the manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard.
WARNING !
Intensive heat radiation. Hands, face and
other parts of the body should be exposed
as little as possible to the heat radiation.
Optical Radiation emission
Category 2 (EN12198)
Siemens Leading Edge Protection Dryer
emits Optical Radiation in form of Infrared
light. Avoid looking directly into the IR
lamps, risk of eye damage. Use IR-protec-
tion glasses.
1.5 Operating personnel requirements
The working platform may only be operated by person-
nel who have been trained and instructed accordingly
or have been authorized to do so. The personnel must
know the operating manual and act according to it.
The respective levels of authority of the operating per-
sonnel must be clearly defined.
Moreover, specific qualifications are required for some
activities; see appendix 1, Manual 761-054_PNTS-77
chapter 6.4.
2. Intended use of the product
This product serves exclusively to accelerate the dry-
ing/curing of Siemens Leading Edge Protection. Its site
of use is the preparation area and finishing area. The
product must not be used for other purposes than the
described drying process. The maximum ambient tem-
perature during operation should not exceed 30°C. The
IRT Siemens Leading Edge Protection Dryer must not be
used within a distance of 5 m from spraying activities in
order to avoid explosion risk. No people are allowed to
be present beneath the platform during the operation.
Working under the raised working platform and during
its lifting and lowering movements is not permitted.
3. Product description
The IRT Siemens Leading Edge Protection Dryer is a
maneuverable infrared dryer.
The infrared drying system is equipped with nine IRT Sin-
gleHeaters in a frame mounted on a Herkules pneumatic
lift. Each IRT SingleHeater is equipped with one infrared
(IR) lamp and has a gold-coated reflector. IR lamps are
easily exchangeable and the reflectors are protected
against mechanical damage by a mesh. The design com-
bined with the possibility to linear lifting and lowering,
enables ergonomically drying at various heights from
850 mm to 2650 mm. The lifting and lowering of the IR
platform works solely with compressed air. The roller
system enables the dryer to be positioned precisely and
the integrated brakes stop it from rolling any further and
this increases the overall safety. Operation of the IRT
Siemens Leading Edge Protection dryer is controlled by
an integrated control unit.
3.1 Particular advantages
3.1.1 Higher quality
The short-wave IR curing enables the coating to be cured
from the inside outwards. This prevents solvents to be
trapped inside the coating and ensures a fast and high
quality curing.
3.1.2 Regulated temperature
The dryer has a pyrometer which carefully controls
temperature of the object. The computer does not only
measure the maximum allowed temperature but also the
temperature raise. It ensures that the programmed dry-
ing/curing temperature is maintained, thereby achieving
optimum curing, without risk for “over burning”.
3.1.3 Hi-tech shape of reflectors with short wave IR
By using short-wave technology and gold-coated reflec-
tors with a high tech shape, important advantages are
achieved. Firstly, by radiating only the needed areas
and not heating any air, a lower energy consumption is
achieved. Secondly, a more uniform surface temperature
is obtained by distributing the energy evenly. Thirdly, a
larger drying surface is achieved. Fourthly, less radiation
outside the curing area.
3.2 Technical data IR heating system

Only qualified persons heeding the safety instructions
are permitted to carry out the installation work.
• The dryer must be examined for any possible trans-
port damage before starting the installation work.
• Ensure that only authorized persons are in the work-
ing area and that no other persons are at risk due to
the installation works.
• All machine connections (hoses) must be laid so that
there is no risk of tripping over them.
• Also read the General Safety Instructions chapter.
• Unauthorized tampering invalidates the guarantee.
5.1 Environmental installation conditions
Siemens Leading Edge Protection Dryer is only suitable
for use in enclosed, dry and covered premises.
Ensure that there is sufficient space away from objects,
walls and ceilings before installation.
It is important to ensure that the minimum distances (ac-
cording to the relevant national regulations and work-
place regulations) to the hall walls or other equipment,
escape routes, etc. are kept to ensure safe working.
The floor should be flat with a maximum gradient of
2.5% (1/40, i.e., 2.5 cm per 100 cm) and the load capac-
ity of the floor must be able to bear the permissible total
weight of the dryer. The operator of the dryer is respon-
sible for selecting a suitable installation site.
The dryer is only to be used at sites with temperatures
ranging from 10°C to 50°C.
An adequately sized compressed air connection (hose
1/2 “, Pmax = 8 bar) must be provided.
Use dehumidified, non-lubricated compressed air only.
A filter regulator must only be installed in the air supply
line (air filter and water separator).
6. Basic instruction for operation
Move the dryer to the site where you want to use it. This
can only be done from the shorter side of the undercar-
riage with help of a fork lift or by pushing or pulling in
the four handlebars one at each corner of the mobile
dryer. For manual movement it is recommended to be at
least two persons to maintain safe and ergonomic work.
The dryer is only to be moved when it is in the start posi-
tion (completely lowered) and without anybody or any
load on it.
Small adjustments length and sideways can be made
in elevated positions to get the green lights from the
distance indicators. All movements of the IRT Siemens
Leading Edge Protection Dryer are to be made with help
of the four handle bars one at each corner at the base.
No adjustments or movement of the dryer are to be
made by applying force to the scissor/lifting part of the
mobile dryer or frame with the IR heaters mounted on
the lifting platform.
Stop the undercarriage from moving by locking the
brakes on the four rollers. Check that the brakes are
working!
Watch your step carefully and keep a safe distance from
other objects, escape routes, walls and ceilings.
The maximum permissible gradient is 2.5% (1/40, cor-
responding to 2.5 cm per 100 cm).
Use a coupling connector to connect to the line’s quick-
release coupling (Pmax = 8 bar/on-site supply). The
coupling must lock into place!
The dryer has an EMERGENCY-RELEASE switch. The
platform can be lowered by a person standing next
to the platform in the case of a control valve failure. In
this case, the emergency release switch must be held
pressed down until the start position is reached.
Proceed as follows to lift the IR platform:
Open the shut-off valve on the hand lever valve. Press
the hand lever valve upwards and hold it until there until
the required lifting height or the end position is reached.
Take note of the hazardous areas whenever possible.
Releasing the hand lever valve automatically returns the
valve back to the 0 position and the lifting process is ter-
minated immediately. The lifting process stops automati-
cally when the maximum lifting height is reached.
Proceed as follows to lower the IR platform:
Check the hazardous area to make sure no persons or
objects are in the dryer´s working area.
Press the hand lever valve downward and hold it there
until the start position is reached or the lowering process
is automatically terminated. Take note of the hazardous
areas whenever possible.
Releasing the hand lever valve automatically returns the
valve back to the 0 position and the lowering process is
terminated immediately.
Close the shut-off valve on the hand lever valve before
leaving.

Tips: When starting in the lowest position, the lift can
jump a small distance; fine tuning of height is done
instead by lowering the lift to the right position
6.1 Start up
Carry out the following functional checks before use:
• Ensure that no persons or objects are in the working
area of the dryer.
• Ensure that the compressed air supply and electric-
ity is available.
• Shift the switch lever on the pneumatic control panel
to the lift-UP position until the IR platform reaches
the upper stop position.
• Shift the switch lever on the pneumatic control panel
to the lower-DOWN position until the IR platform
reaches the lower stop position.
• Repeat the lifting and lowering movements several
times.
Also, see Chapter 1 Safety Instructions.
6.2 Compressed air connection
Use a coupling connector to connect up to the line’s
quick-release coupling (R ½“ on-site supply). The cou-
pling must lock into place!
Use dehumidified, non-lubricated compressed air only.
Connect the air supply line before starting work and
disconnect again after leaving the working platform.
A filter regulator must be installed in the air supply li ne
(air filter and water separator).
6.3 Operation of the IR lamps
Control panel
1. The lights turn green when the correct distance
obtained between IR lamps and object. This distance
must be checked before the IR lights turned on. During
operation with IR lamps, these lights may blink because
of distance sensors are disturbed by the infrared light.
Note the lights are only an aid to find the right position
towards the object it is possible to start the IR lamps
although the lights are not green.
2. Start of the fully automatic IR program. Infrared
lamps turn off automatically after the drying period ends.
3. Infrared lamps, manual stop of process.
4. Indicator light that indicates that a process failure
occurred. The alarm only stops the actual zone that has
the failure. See also Appendix 1.
5. Emergency stop IR lamps.

8. Extended usage information
8.1 Temperature control (OPTION)
The dryer is equipped with an automatic temperature
control. This enables optimum drying/curing results
within the shortest possible time.
The properties when the temperature control is on are:
a. minutes
b. temperature increase/minute
c. max allowed temperature
The temperature control (pyrometer) measures the
average temperature over a surface. The laser pointer
indicates where the distance check is made. This pointer
is close to being in the centre of the temperature mea-
surement also.
In settings mode, the short and long limit for a “correct”
distance measurement can be adjusted. Default correct
distance is between 55 and 65 cm.
Note! The temperature is measured as an average of the
measured surface (default diameter value 30 cm, other
optics are available). Make sure to have the measur-
ing surface placed correctly. Make sure that you don´t
measure the temperature on glass, tyres or outside the
object. Otherwise, the result between the programmed
temperature values and actual values may differ. This
may lead to unsatisfactory results and if the process
alarm is activated it will stop the drying/curing.
With the temperature control deactivated, the program
properties are:
a. minutes
b. percent power of max possible
The program settings with or without the temperature
control activated are working independently of each
other.
8.2 Process alarms (OPTION)
To notice temperature deviations, the dryer is equipped
with a process alarm. If the difference between the
current temperature and the requested temperature is
more than 30ºC (adjustable, see 9.4.28), the message
“Warning! Process error” appears in the display and the
dryer switches off automatically. This warning has to be
acknowledged by pressing enter. By doing this, the pro-
gram is terminated. In case of process alarm, check if the
temperature measuring device (pyrometer) is aligned
correctly on the surface to be dried and that it is not
registering unwanted material temperatures.
Attention! The process alarm function is not activated
when dryer is delivered.
Please see chapter 9.4.3 for activating.
8.3 External start and stop
There is an input in this SingleHeater Control Unit to
enable a remote start and stop of the drying process.
This function can be integrated in the overhead process.

9.4.25 53 Pyro Regulator I (Integral)
This option, together with 9.4.24, is used to fine tune the
heating system depending on the pyrometer readings.
By tuning the two parameters P and I in the PID control-
ler algorithm, the controller can provide control action
designed for specific process requirements. The re-
sponse of the controller can be described in terms of the
responsiveness of the controller to an error, the degree
to which the controller overshoots the set point, and the
degree of system oscillation.
To alter the values for P and I full understanding of PID
controllers is needed.

Maintenance work is to be carried out at the stipulated
maintenance intervals by suitably trained personnel.
Do not use running water or flammable liquids for clean-
ing.
Abide by the following points to ensure a long service
life and continuous operation of the dryer:
• Only original spare parts and suitable tools are to be
used.
• Adhere to the maintenance intervals.
• Contact your dealer or the manufacturer’s customer
service department regarding any maintenance
work that is not listed or shown in this manual.
Only undertake maintenance work when the maximum
lift (unloaded) is reached, the platform table has been
reinforced by service supports (part no. 195682) or
secured by a forklift at the top position and the com-
pressed air supply and electricity has been shut off.
10.1 Maintenance
Weekly
Check that all IR lamps light up during dryer operation.
Defect IR lamps can cause uneven heat distribution over
the surface.
Clean the dryer from dust, which can be a cause of fire,
with a damp cloth.
Check that all cables are undamaged. A damaged cable
can be a danger to life!
Monthly
Check the gold coated reflectors. Damaged or extremely
dirty reflectors can overheat the reflector body and/
or the cassette. In case of doubt, please contact the
customer service in order to clarify if the gold coated
reflector needs to be changed.
Check all moving parts such as pivot bolts, sliding pieces
and sliding surfaces for wear and tear; clean and lubri-
cate. Only use greases in the lacquer coated sections
that do not contain substances that might damage the
lacquer coating.
Check air bellows and air hoses for damage. Inspect
visually and check for leaks. Check the surface of the air
bellows for contamination; clean and maintain. Always
use appropriate care and cleaning products when carry-
ing out maintenance on the rubber surfaces.
Check that the valves are working correctly and check for
leaks.
Inspect the service unit provided by the customer (filter
regulator) and abide by the instructions in the manufac-
turer’s manual.

10.4 Air bellows
The air bellow is a flexible element specially designed for
use in the lifting platform. The rubber cover is subject to
aging processes and must be checked carefully. Record-
ed data shows that a well-kept air bellows has a service
life of over 20 years.
Tips for a long service life:
• Use dry and oil-free compressed air.
• Protect from UV radiation (e.g. from welding or UV
dryers).
• Avoid the use of chemical products.
• Protect from mechanical damage (dents, etc.).
• Abide by the maintenance and care instructions, see
10.1.
Damaged air bellows must be replaced. Only original
parts from the manufacturer can be used
10.5 Comments on the filter regulator and air
supply lines
The filter regulator is not included in the Siemens Lead-
ing Edge Dryer package. A filter regulator must be in-
stalled in the air supply line (provided by the customer).
Use dehumidified, non-lubricated compressed air only.
Follow the instructions and recommendations provided
by the manufacturer of the filter regulator during mainte-
nance and cleaning.
10.6 Comments on the scissors' sliding areas
Due to the design principles, very strong forces are pres-
ent on the sliding surfaces of the scissors. These forces
can lead to grooving in the sliding surfaces. They will not
affect the operation of the dryer.
The maintenance intervals described in 10.1 and other
manuals must be adhered to.
