Safety instructions

The Raw Density Measuring System has been built in accordance with state-of-the-art standards
and is fail-safe. Nevertheless, you have to observe all safety instructions to protect persons against
injury and the StenOgraph system against damage.
Therefore please read the safety instructions of this manual cautiously.

The StenOgraph system has been provided with comprehensive safety

features. The safety circuit encompasses the pneumatic equipment, the
water cooling equipment, the position indicator switch, the emergency
shutdown features and the X-ray generator.
By means of this circuit the movement and the pressure of both the
compressed air and the water in the cooling system are monitored. In case
of a trouble or when an emergency shutdown button is pressed the X-ray
generator is automatically switched off.
You will find further information on the components of the safety circuit in
chapter „Technical Description“.

Designated use

The StenOgraph is designed exclusively for the measuring the raw density of panel samples.
Using the StenOgraph system for purposes other than this is considered contrary to its designated
use.
On no account undertake any unauthorized modification or conversion of the StenOgraph system.
The manufacturer cannot be held liable for any damage resulting from such use.
Operating the Density Analyzer within the limits of its designated use also includes observance of
the instruction manuel.

Basic rules for safety-conscious operation

Documentation
Always have the instruction manual ready to be consulted near the StenOgraph system.

Operation
Ensure that the Raw Density Measuring System StenOgraph is operated exclusively by personnel
who were given specific training to do so by GreCon service engineers during the commissioning of
the system.

 Safety

Qualified personnel
Ensure that all work on the electric components of the StenOgraph system is carried out by
properly qualified electrical engineers only and in accordance with the electrotechnical regulations
applied.
Ensure that all work on the pneumatic components of the StenOgraph system is carried out
exclusively by personnel with special knowledge of pneumatic technology.
Caution X-ray! - Control zone
A particular area around the measuring system is to be designated as a control zone according to
the radiation dose output of the source asmeaasured by the person responsible for radiation
protection. The control zone is marked by correspondend shields and shut off. Do not take out any
changings at the safety measures.
Caution X-ray! - Signalling lights
The O-frame of the measuring system is equipped with two signalling lights which indicate the
current status of the X-ray source.
Red flashing signalling light means: X-ray source active

Ensure that inspections and maintenance are only carried out when the measuring system is
switched off.
Caution high voltage !
The X-ray source is operated with high voltage. The control for the X-ray unit is located in the
switch cabinet. The operational readiness of the X-ray generator is switched on by means of a key-
operated switch.
Production stop
On no account should inspections and maintenance duties be carried out when production is in
progress. Make use of production standstill periods to carry out work of this nature.

Safety of the system

The O-frame of the system must not contact the roller conveyor. Otherwise oscillations of the roller
conveyor could be tansferred to the system and the measurement results would be falsified.
To garantee a trouble-free work of the system, the O-frame has to be grounded by a flexible ground
wire.

Safety

Rectify any malfunction immediately on occurence. In case you are unable to eliminate a problem
yourself, please contact our service department or your nearest GreCon agent.

Important indications on the protection against radiation

The source of the StenOgraph system is an X-ray source with collimator. For this reason the
system is subject to national laws and regulations, for example about operating permits.

Operating permit
Operation of the X-ray source requires official approval and must be registered with the appropriate
authority by the user. For this purpose, we provide you with „Application documents for operating
permits“.

Installation of the X-ray source

The X-ray source may be installed in the system by a GreCon service technician only. After the
source has been installed, it may never be taken out of the system.

Protection against radiation

During operation the person responsible for the safety of systems measuring with X-ray sources in
the plant is responsible for the StenOgraph system. The GreCon service technician hands over the
measuring system when commissioning. The responsable also has to ensure the observance of
and compliance with national laws and regulations for protection against radiation.

On-site protective facilities

It is the obligation of the responsable for protection against radiation to measure the dose output of
the source and designate a particular area around the measuring system as control zone in
accordance with the local regulations about radiation protection. This control zone must be closed
off with a safety screen and marked accordingly. Entry of the control zone by unauthorized persons
is prohibited.

Tests by the authority concerned

The X-ray source must be checked regularly by the authority concerned. The intervals of testing
are determined by the authority when registrating the source.

Overview of functions of the Raw Density Measuring System StenOgraph

The GreCon-Raw Density Measuring System StenOgraph is intended for the in-line, real-time
determination of the Raw Density of moving wood-based materials directly at the outlet of a
continous press.
The measuring principle of the Raw Density Measuring System StenOgraph is based on a
combination of transmission and spread forward of x-rays.
A very tight marked-off x-ray permeates the cross section of the moving board in an ancle of 45:
A movable detector system absorbs the density depending scatter along the beamed on plane and
a static detector absorbs the transmitted radiation.
By combining both signals the Raw Density can be calculated directly at each point of the board
cross section, undependently of the circumjacant structure. By this means the total density and
also the partial volumes can be determined.

 Technical description

Ultrafilter

Position: The pneumatic equipment is located on the side wall of the swich box for the X-
ray generator.

Function: The ultrafilter cleans the compressed air from solid particles and moisture.
Particles bigger than 40 µm (independent of the filter element), are held back
by a sintered filter. Liquids are separated by a special device and led into the
filter bowl. The condensed liquid collected in the bowl is let off from time to time
for not being transported with the air.
The finest filters (5) clean the control air nearly completely from the smallest
water and oil drops and diret paritcles still contained in the compressed air. In
this process the compressed air is filtered by 99,999% (based on 0,01 µm).

The filter control valve (3) keeps the operating pressure (secondary site)
constant, independent of pressure variations in the circuit (primary side) and the
air consumption. The admission pressure must always be higher than the
operating pressure.
Components: 1 = Input-sided screw joint
2 = Switching valve: for the ventilation of pneumatic units
3 = Filter with regulating valve and automatic purging of the condensed water
4 = Finest filter with automatic purging of the condenesed water: bigger
particles (up to 1 µm) are filtered by being hold back in fibre textures. They form
bigger drops that run off because of gravity.

 Mounting

Mounting the oscillation absorbers

z Lift the O-frame using a crane.

Therefore only use the transportation loops!

z Remove both wood beams by releasing the screws.

z Screw the oscillation absorbers (see fig. 7).
z Make a first rough height adjustment of the oscillation absorbers (approx. 100mm).
z Evenly tighten the nuts.

 The O-frame is mounted on the prearranged H-beam (recommendation:

DIN 1025 IPB 200)or an prepared foundation by means of the oscillaton
absorbers after installing in the transport system. Provide for the drill holes
necessary for attaching the O-frame.

Installing the O-frame in the production system

Before installing the O-frame you have to check whether there are short
panel parts remain in the system after the guidance table has been
installed. If this is the case you might have to tanke corrective actions by
installing press-on rollers.

The O-frame can be installed completely in the production system.

 Do not remove one of the uprights. Thus, the O-frame might be damaged!

For the installation of the O-frame it is necessary to open the production system at the allocated
installation site. The required hole in the production system measures max. 500mm.
Position the O-frame carefully in this opening in the production system.

Mounting

Adjusting the height of the O-frame

z Secure the O-frame in order to prevent it from falling over using appropriate diagonal
braces.
z Move the O-frame until the panel passes the O-frame exactly concentrically (or as
indicated).
z Adjust the working level by means of the oscillation absorbers located at the feet of the O-
frame.

 The height of the marking „Zeropoint“ (on the inner side of the O-frame) has
to coincide with the surface of the surface of the roller conveyor.

Fig. 7: Oscillation absorber

You have to observe the given dimensional tolerances! Make sure that the
O-frame is in an absolutely rectangular positon.

Adjusting the position of the beams and uprights to one another

Adjust the horizontal beams using the diagonal braces located at the sides. In order to do so you
need:

z 17 spanner
z auximaliary mounting devices (included in the scope of supply)
z clock gauge
z angle

Fig. 8: Lateral view

Using the angle make sure that all axes (x, y and z) are positioned
rectangular to one another!

645558 01 0 45
Mounting

Aligning the measurement carriages

Before starting the alignment check the following:

z Is the O-frame located at the intended installation position?
z Have the fastening screws been securely tightened?
z Does the „Zeropoint“ coincide with the surface of the roller conveyer?
z Are the beams and uprights of the O-frame rectangualar to one another?
z Have the transportation means been removed?
For O-frame with drive:
z Check the correct positioning of the connecting shaft and of the shaft protection
z Check the power bridge

Attaching the auxiliary mounting device

z Attach the auxiliary mounting device (aluminum profile) at the front right side of the carriages
(see figure).
z Fix the clock gauge as displayed.

Fig. 9:Auxiliary device with clock gauge

 The separating point of the aluminum profiles has to be at level zero.

46 645558 01 0
 Mounting

Option: Synchronization of the upper and lower carriages

z Manually move the carriages to one end

of the O-frame and observe the position
of both carriages to one another.

z Displace the carriages as far as possible and observe the position of the aluminum profiles to
one another.

z If the profiles are not located above one

another this can be compensated by
retightening one of the belts. Retighten-
ing is only carried out with the belt that
has travelled the shorter distance.
(The tightening distance of the belt ten-
sioner is approximately twice the differ-
ence of the two measurements.)

 All in all, the belt must not be tightened longer than 2/1000 of the belt
length!

z Again check the synchronous running and repeat the tightening process if neccessary.
z Protect the clamping bolts against twisting by locking the nuts.

645558 01 0 47
Mounting

Adjusting the traversing quality of the carriages

z Move the carriages to the left side of the O-frame.

z Set the clock gauge to zero.
z Move the carriages to the right side of the O-frame.
The clock gauge displays a value other than zero.
z Turn the clamping elements until the clock gauge is at zero.
z Move the carriages back to the left side.
z Repeat the procedure until the clock gauge is at zero on both sides.
Now, the carriage has the optimum traversing quality.

It is sufficient if zero is reached at the ends of the O-frame. At the centre,

material deflections of the profile take effect which do not allow for an
adjustment at this point.

Adjusting the lower measurement carriage

The measurement carriage has been preadjusted ex works so that it only has to be realigned by
way of exeption.
z Detach the bolts marked below.
z Correct the position using the adjustment screws.
z Tighten the fastening bolts.

Fixing the O-frame

Attach the oscillation absorbers located below the O-frame (figure see page 14) on the H-beam to
be provided by the customer (recommendation: DIN 1025 IPB 200) or on the prepared foundation.

 Provide for the drill holes necessary for attaching the O-frame in time.

Electrical connection

 Cables for measurement and control may not be laid together with other
control or power cables. They must be laid in a seperate cable duct and be
shielded.

The maximum cable lenght between the O-frame and the switch cabinet is
15m. When selecting the installation sites you have to consider that this
cable length already includes laying the cables inside the O-frame.
In order to ensure the correct and trouble-free functioning of the measuring
system the O-frame has to be connected to a ground wire. The cross
section of this ground wire has to be 10mm² and its impedance may not
exceed 5 O.
