1Introduction
1.1 Intended use
The CONTADOR 2 Seed Counter is used to count cleaned seeds such as grain, oil seeds, corn legumes and
similar, dust-free products in order to establish, for example, the thousand seed weight. The maximum
counting rate is 5.000 seeds/min.
It is controlled by the three function keys which are fitted to the machine and also the RS232 interface,
e. g. using the PC software "SeedCount" which is available as an accessory.
The Filling Station, CONTAFILL 2, is required as an accessory for automatically filling the counted seeds
into bags or bottles.
The CONTADOR 2 is designed as a as a portable device with an associated desktop power supply with
power plug for interiors (laboratory environment).
A private use of the CONTADOR 2 Seed Counter is not permitted.
NOTICE The CONTADOR 2 is designed to be used exclusively for the purpose described.
Any use or modification that does not have the prior written approval of the
manufacturer shall be considered as improper use. The manufacturer assumes no liability
for damage caused by improper use. The operating company is solely responsible for any
damage resulting from this.
The CONTADOR 2 may be put into operation only once it has been established that all
the safety equipment is functioning.
The machine cannot be used to count dressed seeds, items made of static plastic parts
and dusty products. This can cause the light barriers to become soiled.
The CONTADOR 2 is not suitable for liquid and sticky products.
The CONTADOR 2 is not intended for operation in potentially explosive atmospheres.
The samples that are used for the intended use must be procured by the CONTADOR 2
operating company.
The operating company is solely responsible for the proper handling of these materials
and the associated hazards.
The operating company must provide hazard and disposal information.
Intended use includes also the compliance with the Instruction Manual and User´s Guide as well as the
maintenance and servicing conditions, as specified in these Operating Instructions.
These Operating Instructions do not relieve the operating company of the obligation to develop and to
apply independent health and/or safety regulations or safe working processes which are aimed at the
requirements of the overall machine, as well as the obligation to monitor their compliance.

in idle mode (without product in the feed container)
The noise level can increase because of the nature of the product to be counted (e.g.
with heavy, hard seeds such as beans and maize) and due to structure-bound noise.
Particularly if several Seed Counters are being operated in the same room at the same
time (laboratory environment).
It is the responsibility of the operator to check the noise level on site and then take
appropriate measures (produce risk assessment if necessary wear hearing protection
etc.).
4Delivery, transport and storage
The Delivery, transport and storage chapter is only intended for specialist operators.
4.1 Standard equipment supplied
The standard scope of delivery to the owner comprises: CONTADOR 2 Seed Counter, desktop power

then loads the optimum parameters for this.
Having set the counted quantity, the count starts.
The feed container is held by a magnet and is kept vibrating by means of a vibration element. The vibration
causes the product to be counted to flow through the gate of the feed container and it distributes itself
evenly on the five counting channels where it is separated.
The optimum feed speed is ensured by a counting algorithm. The channels guide the product to be
counted to the outlets where it falls through the light barriers and into the drawer.
A connected air pump ensures a continuous flow of air which prevents abrasion or dust particles which
could impair the function of the light barriers.

5.4 Filling Station CONTAFILL 2 (option)
The CONTAFILL 2 Semi-automatic Filling Station is
used to quickly fill small batches of seed, grains and
similar products (refer to chapter 1.1) in any quantity
(from 1 to 99.999) in bags (paper/plastic) or bottles
(plastic/glass).
The CONTAFILL 2 consists of a stainless steel housing
with interchangeable carousels for 10 bags or bottles
of between 50 and 200 mm in length, and installed
electronic sensor for detecting the bags.
Transparent bags and bottles are not detected by the
sensor. This can be remedied by attaching a label.
Refer to chapter 6.4
for more information about
assembling and operating the CONTAFILL 2.

Figure 12: Suitable bag sizes Figure 13: Stand with carousel
When operating mode P is selected (refer to chapter 7.5.1), a carousel with full bags can be removed
from the CONTAFILL 2 and a second carousel with empty bags inserted.
The filling process can be continued while the full bags from the first carousel are being removed and it is
then provided with empty ones for the next pass. The stand, which is available as an accessory, makes
this process a lot easier.
5.5 PC software "SeedCount" (option)
The software enables series of samples to be filled together with the Filling Station, CONTAFILL 2. You can
specify the number of bags and the desired number of seeds. Heterogeneous count lists can be processed
in the form of XLS tables. A label printer prints out data such as the test location and number of seeds.

6Installation and commissioning
The Installation and operation chapter is intended only for specialists.
6.1 Assembling the CONTADOR 2
Carefully unpack the CONTADOR 2.
A correct, horizontal assembly of the machine guarantees an even distribution of the
seeds in the feed channels.
Figure 14: Check assembling with spirit level
Place the CONTADOR 2 horizontally
on a solid table with a smooth, clean
surface.
Use a spirit level for this purpose.
Figure 15: Unscrew foot and put on washers
If necessary, you can unscrew the feet
of the CONTADOR 2 and, for example,
put on one or two washers to align the
device.
Ensure that a firm footing on a non-slip surface is provided.
The CONTADOR 2 exerts vibration forces on the base. Do not set up the CONTADOR 2 close to
apparatus that are sensitive to vibration.
Make sure there is an adequate distance to all sides so that no heat buildup can occur.
Installation in unheated, draughty and dusty surroundings can have a negative effect on
the service life of the CONTADOR 2.
Avoid exposure to direct sunlight and extreme ambient conditions.
