About this document

Please read this chapter carefully before working with this documentation and the AHS/
AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox Absolute encoder.

1.1

Scope

NOTE

These operating instructions apply to the absolute encoders AHS/AHM36 SAE J1939
and AHS/AHM36 SAE J1939 Inox with the following type designations:

Singleturn Encoder Basic = AHS36B-xxJx004096

Multiturn Encoder Basic = AHM36B-xxJx012x12

Singleturn Encoder Advanced = AHS36A-xxJx016384

Multiturn Encoder Advanced = AHM36A-xxJx014x12

Singleturn Encoder Inox = AHS36I-xxJx016384

Multiturn Encoder Inox = AHM36I-xxJx014x12

1.2

Function of this document

These operating instructions are designed to address the technical personnel of the
machine manufacturer or the machine operator in regards to correct configuration,
electrical installation, commissioning, operation and maintenance of the AHS/AHM36
SAE J1939 und AHS/AHM36 SAE J1939 Inox Absolute encoder.

1.3

Target group

The operating instructions are addressed at the planners, developers and operators of
systems in which one or more AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939
Inox Absolute encoder are to be integrated. They also address people who initialize the
use of the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox or who are in
charge of servicing and maintaining the device.

These instructions are written for trained persons who are responsible for the installa‐
tion, mounting and operation of the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE
J1939 Inox in an industrial environment.

1.4

Information depth

These operating instructions contain information on the AHS/AHM36 SAE J1939 und
AHS/AHM36 SAE J1939 Inox Absolute encoder on the following subjects:

product features

electrical installation

commissioning and configuration

fault diagnosis and troubleshooting

conformity

These operating instructions do not contain any information on the mounting of the
AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox. You will find this informa‐
tion in the mounting instructions included with the device.

They also do not contain any information on technical specifications, dimensional draw‐
ings, ordering information or accessories. You will find this information in the product
information for the AHS/AHM36 SAE J1939 und AHS/AHM36 SAE J1939 Inox.
