2Safety Instructions
This product has been manufactured in accordance with the generally recognized
rules of technology. Nevertheless, there is a risk of personal injury and material dam-
age if you do not observe this chapter and the safety instructions in this documen-
tation.
Read this documentation thoroughly and completely before working with the

Store the documentation in such a way that it is always accessible to all users.
Always pass on the product to third parties together with the required docu-
mentation.
2.1 Intended Use
The interpreter is a component of guide wire track guidance systems for Automated
Guided Vehicles. The interpreter detects the deviation from the guide wires laid in
the ground by means of the antennas mentioned in section 3.1 on page 12 and
transmits it to the vehicle controller. Based on the transmitted values the steering in-
formation can be calculated.
The connected antennas are monitored for correct operation as well as for wire
breakage. The interpreter is only intended for the use in track guidance systems with
a maximum speed of 1 m/s without any passenger transportation.
Main area of application is the steering of automated guided vehicles, thus this is the
application we mainly address from here on.
The track guidance system may only be operated by qualified personnel at the oper-
ation place (e.g. vehicle) at which it was mounted or initially commissioned by qual-
ified personnel according to this device description. The operating conditions given
in section 2.4 on page 9 have to be observed.
The track guidance system does not include safety equipment. It may only be used
in applications where the manufacturer and/or the facility operator have ensured
that sufficient measures for ensuring the personal safety and the safe detection of
obstacles have been established. This includes the safe detection of situations like
e.g. the vehicle leaving the track or people or obstacles appearing in front of the ve-
hicle. In these cases moving parts (e.g. vehicles) have to be stopped immediately to
rule out material damage and personal injuries.
All persons within the range of influence of an automated facility (e.g. automated
guided vehicle, AGV) have to be instructed about the kind of the application and the
associated risks.
2.2 Improper Use
Any use other than that described in the intended use is not intended and therefore
not permitted.
Götting KG does not accept any liability for damage caused by improper use. The
risks of improper use lie solely with the user.

Safety Instructions – Chapter 2
Improper use includes:
The use of the track guidance system in vehicles that are not equipped with
safety devices for personal protection and safe detection of obstacles.
Any departure from the lane or the appearance of a person or an obstacle in the
danger area must be reliably detected at all times and immediate stopping of
moving parts (e.g. vehicles) must be ensured to prevent damage to property or
persons.
2.3 Qualification of the Users
The tasks described in this document require basic knowledge of the mechanics and
electrics as well as knowledge of the associated technical terms. In order to ensure
safe use, these activities must therefore only be carried out by an appropriate spe-
cialist or an instructed person under the supervision of a specialist.
A qualified person is someone who, on the basis of his or her specialist training,
knowledge and experience as well as knowledge of the relevant regulations, is able
to assess the work assigned to him or her, recognize possible dangers and take ap-
propriate safety measures. A qualified person must comply with the relevant tech-
nical regulations.
The personnel intended for the installation, commissioning and configuration of the
track guidance system:
has received a copy of this device description.
is familiar with the functionality of the superordinate system (e.g. an automated
vehicle).
is qualified to perform their tasks and is sufficiently trained to mount and con-
figure the track guidance system, if that is part of their tasks.
is familiar with the commissioning of and the telegram exchange via CAN bus
or Profibus connections.
knows – in case the track guidance system is to be used to position automated
vehicles – the dangers emanating from an Automated Guided Vehicles (AGV)
and is sufficiently trained in handling the vehicle and any necessary safety pre-
cautions to assess the safe working condition of the system.
knows – in the event that other equipment or systems with moving parts are
used – the risks arising from the application and is sufficiently trained in the
handling of the vehicle and any necessary safety precautions to assess the safe
working condition of the system.
2.4 Operating Conditions
Observe the conditions for the installation of the antenna given in the related
documents (s. section 1.1.2 on page 5), especially the specifications for metal
free areas around the antenna and the interference immunity.
Reinforcements close to the surface of the roadway may interfere the antenna
and thus distort the position detection. This also applies to any large metal
pieces (sheets) on the ground, the proximity of any floor reinforcement and
inductive loops, as they are created e.g. by steel building mats. Individual metal
poles have little effect. Those may partially be within the metal-free area of the
guide wire.
For the size of metal-free areas around the antenna please see the appropriate
data-sheets listed in section 1.1.2 on page 5.

Device Description HG G-7335xZA | English, Revision 05 | Date: 19.02.2020
10 Chapter 2 – Safety Instructions
The nominal reading distance between antenna and wire depends on the
antenna type and the wire current. In between antenna and guide wire there
may be no metal. Non-conducting and non-shielding dirt on the roadway as
well as water, oil, tar, earth, fog, snow and ice do not influence the positioning.
Even though dirt does not influence the positioning the antenna should be pro-
tected against dirt and moisture (e.g. spray water from the vehicle‘s wheels) and
cleaned regularly. Otherwise the antenna‘s attrition rate rises.
The antenna has to be fixed to the vehicle so firmly that its position does not
change during normal operation. Otherwise the superordinate system interprets
the position data wrongly and the vehicle might e.g. drive besides the track.
After the mounting interferences should not exceed 500 units. This closely
relates to the quality of the wire signal. This signal has to be significantly higher
than interference signals. The more interference is radiated especially into the
differential antenna, the less accurate the distance output becomes.
Generally interferences should be avoided by keeping sufficient distances to
interference sources and consistent reading distances to the guide wire.
In the selected frequency area there may be no interference signals from
clocked motors etc. This includes interferences transmitted via the metal body
of the vehicle. Since magnetic fields may be transmitted via chassis parts it is
advisable to perform tests when in doubt.
Cables have to be installed with a minimum distance of 150 mm from the
antenna since those cables can interfere with the antenna reception. How
much they interfere depends on the power and the frequency. Again it‘s import-
ant that the interferences are not higher than 500 units.
The system is intended to be used indoors. The operating temperature range is
0 to +50° C.
Relative humidity 95 % @ 25° C (without condensation).
2.5 General Safety Instructions
The track guidance system does not include safety equipment. It may only be
used in applications where the manufacturer and/or the facility operator have
ensured that sufficient measures for safeguarding the personal safety and the
safe detection of obstacles have been established.
The manufacturer and/or the facility operator have to ensure the safe detection
of situations like e.g. the vehicle leaving the track or people or obstacles appear-
ing in front of the vehicle. In these cases moving parts (e.g. vehicles) have to be
stopped immediately to rule out material damage and personal injuries.
When using the track guidance system the operating conditions from section
2.4 on page 9 have to be observed.
Ensure that interferences in the ground or on the vehicle do not induce a higher
signal than 500 units in the antenna. Make sure that the guide wire has a suffi-
ciently higher signal. Otherwise measuring errors may occur.
2.6 Obligations of the Operator
When using the track guidance system, the operator must ensure that
all persons within the sphere of influence of an automated system (e.g. Auto-
mated Guided Vehicle (AGV)) are informed about the type of application and the
associated hazards,
