1 General information
1.1 Explanation of symbols
The symbols used in this technical description are explained below.
Attention!
This symbol precedes text messages which must strictly be observed. Failure to observe the
provided instructions could lead to personal injury or damage to equipment.
Attention Laser!
This symbol warns of possible danger through hazardous laser radiation.
Note!
This symbol indicates text passages containing important information.
1.2 Declaration of Conformity
The AMS 301 i absolute measuring optical laser measurement system was designed and
manufactured in accordance with the applicable European directives and standards.
The AMS series is "UL LISTED" according to American and Canadian safety standards and
fulfills the requirements of Underwriter Laboratories Inc. (UL).
Note!
The Declaration of Conformity for these devices can be requested from the manufacturer.
The manufacturer of the product, Leuze electronic GmbH & Co. KG in D-73277 Owen,
possesses a certified quality assurance system in accordance with ISO 9001.

TNT 35/7-24V
1.3 Description of functions AMS 301 i
The AMS 301 i optical laser measurement system calculates distances to fixed as well as
moving system parts. The distance to be measured is calculated according to the principle
of the propagation time of radiated light. Here, the light emitted by the laser diode is reflected
by a reflector onto the receiving element of the laser measurement system. The AMS 301
i
uses the "propagation time" of the light to calculate the distance to the reflector. The high
absolute measurement accuracy of the laser measurement system and the fast response
time are designed for position control applications.
With its AMS 3xx
i product series, Leuze makes available a wide range of internationally rele-
vant interfaces. Note that each interface version listed below corresponds to a different
AMS 3xx
i model.

2 Safety
This sensor was developed, manufactured and tested in line with the applicable safety stan-
dards. It corresponds to the state of the art.
2.1 Intended use
The AMS is an absolute measuring optical laser measurement system which allows distance
measurement of up to 300m against a reflector.
Areas of application
The AMS is designed for the following areas of application:
• Positioning of automated, moving plant components
• Travel and lifting axes of high-bay storage devices
• Repositioning units
• Gantry crane bridges and their trolleys
•Elevators
• Electroplating plants
Attention
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC
(National Electric Code).
2.2 Foreseeable misuse
Any use other than that defined under "Intended use" or which goes beyond that use is
considered improper use.
CAUTION

2.5 Laser safety notices
ATTENTION! LASER RADIATION – CLASS 2 LASER PRODUCT
Do not stare into beam!
The device satisfies the requirements of IEC/EN 60825-1:2014 safety regulations for a
product of laser class 2 product and complies with 21 CFR 1040.10 except for conformance
with IEC 60825-1 Ed. 3., as described in Laser Notice No. 56, dated May 8, 2019.

Never look directly into the laser beam or in the direction of reflected laser beams!
If you look into the beam path over a longer time period, there is a risk of injury to the
retina.
 Do not point the laser beam of the device at persons!
 Interrupt the laser beam using a non-transparent, non-reflective object if the laser beam
is accidentally directed towards a person.
 When mounting and aligning the device, avoid reflections of the laser beam off reflective
surfaces!
 CAUTION! The use of operating and adjustment devices other than those specified here
or the carrying out of differing procedures may lead to dangerous exposure to radiation.
 Observe the applicable statutory and local laser protection regulations.
 The device must not be tampered with and must not be changed in any way.
There are no user-serviceable parts inside the device.
Repairs must only be performed by Leuze electronic GmbH + Co. KG.
NOTE
Affix laser information and warning signs!
Laser information and warning signs are attached to the device (see figure 2.1). Also
included with the device are self-adhesive laser warning and laser information signs (stick-
on labels) in multiple languages (see figure 2.2).

Affix the laser information sheet to the device in the language appropriate for the place
of use.
When using the device in the U.S.A., use the stick-on label with the "Complies with
21 CFR 1040.10" notice.
 Affix the laser information and warning signs near the device if no signs are attached
to the device (e.g. because the device is too small) or if the attached laser information
and warning signs are concealed due to the installation position.
Affix the laser information and warning signs so that they can be read without the reader
being exposed to the laser radiation of the device or other optical radiation.

3 Fast commissioning / operating principle
Note!
Below you will find a short description for the initial commissioning of the AMS 301i. Detailed
explanations for the listed points can be found throughout the handbook.
3.1 Mounting the AMS 301 i
The AMS 301 i and the corresponding reflector are mounted on two mutually opposing, plane-
parallel, flat walls.
Figure 3.1: Schematic illustration of mounting
Attention!
For error-free position measurement, there must be an unobstructed line-of-sight between
the AMS 301i and the reflector.
3.1.1 Mounting the device
The laser is mounted using 4 screws (M5).
Alignment is performed using 2 adjustment screws. Adjust so that the laser light spot is posi-
tioned at the center of the reflector. The alignment is secured with the knurled nut and locked
with the M5 nut.
Detailed information can be found in Chapter 5.2 and Chapter 5.3.
3.1.2 Mounting the reflector
The reflector is mounted using 4 screws (M5). The reflector is angled using the spacer
sleeves included. Incline the reflector by approx. 1°.
Detailed information can be found in Chapter 6.4.

Fast commissioning / operating principle
12 AMS 301 i Leuze electronic GmbH + Co. KG
3.2 Connecting the voltage supply
The laser measurement system is connected using M12 connectors. The voltage supply is
connected via the PWR M12 connection.
Detailed information can be found in Chapter 7.
3.3 Display
Once the laser measurement system is supplied with voltage, the device status as well as
the measured position values can be read on the display. The display automatically switches
to the display of the measurement values.
Use the up/down buttons to the left of the display to read and change a wide range
of data and parameters.
Depending on the connected interface, the network address or IP addresses must be config-
ured via the display.
Detailed information can be found in Chapter 8.
3.4 AMS 301 i on the RS 485
The transmission parameters are listed in the menu structure and on the foldout at the end
of the technical description.
The parameters can be changed after activation of parameter enable.
Detailed information can be found in Chapter 9.
