2 Safety information
This chapter deals with your own safety and the safety of the equipment operators.
bPlease read this chapter carefully before working with the AHS/AHM36 SAE J1939
und AHS/AHM36 SAE J1939 Inox or with the machine or system in which the
AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox is used.
2.1 General safety notes and protective measures
CAUTION
Please observe the following procedures in order to ensure the correct and safe use of
the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox!
The encoder is to be installed and maintained by trained and qualified personnel
with knowledge of electronics, precision mechanics and control system programming.
It is necessary to comply with the related standards covering the technical safety
stipulations.
All safety regulations are to be met by all persons who are installing, operating or
maintaining the device:
•The operating instructions must always be available and must always be followed.
•Unqualified personnel are not allowed to be present in the vicinity of the system
during installation and maintenance.
•The system is to be installed in accordance with the applicable safety stipulations
and the mounting instructions.
•All work safety regulations of the applicable countries are to be followed during
installation.
•Failure to follow all applicable health and work safety regulations may result in
injury or damage to the system.
•The current and voltage sources in the encoder are designed in accordance with
all applicable technical regulations.
2.2 Intended use
The AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox Absolute encoder is
a measuring device that is manufactured in accordance with recognized industrial
regulations and meets the quality requirements as per ISO 9001:2008 as well as those
of an environment management system as per ISO 14001:2009.
An encoder is a device for mounting that cannot be used independent of its foreseen
function. For this reason an encoder is not equipped with immediate safe devices.
Measures for the safety of persons and systems must be provided by the constructor of
the system as per statutory regulations.
Due to its design, the AHS/AHM36 SAE J1939 and AHS/AHM36 SAE J1939 Inox can
only be operated within an SAE J1939 network. It is necessary to comply with the SAE
J1939 specifications and guidelines for setting up a SAE J1939 network.
In case of any other usage or modifications to the AHS/AHM36 SAE J1939 und AHS/
AHM36 SAE J1939 Inox, e.g. opening the housing during mounting and electrical
installation, or in case of modifications to the SICK software, any claims against SICK
AG under warranty will be rendered void.

3.2 Operating principle of the encoder
The sensing system in the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939
Inox AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox is based on absolute
acquisition of revolutions without an external voltage supply or battery. As a conse‐
quence the encoder can immediately output its absolute position again after switching
off and switching back on.
The AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox acquires the position of
rotating axes and outputs the position in the form of a unique digital numeric value. The
highest reliability is achieved by means of electrosensitive, magnetic scanning.
The AHS36 is a singleturn encoder.
Singleturn encoders are used if absolute acquisition of the rotation of a shaft is
required.
The AHM36 is a multiturn encoder.
Multiturn encoders are used if more than one shaft revolution must be acquired abso‐
lutely.
3.2.1 Scaleable resolution
The resolution per revolution and the total resolution can be scaled and adapted to the
related application.
The resolution per revolution can be scaled in integers from 1 … 4,096 (Basic) or from
1 … 16,384 (Advanced / Inox).
The total resolution of the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox
must be 2ⁿ times the resolution per revolution. This restriction is not relevant if the
round axis functionality is activated.
