General information

1.3 Description of functions AMS 338 i
The AMS 338 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 338
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.

Certified electricians
Electrical work must be carried out by a certified electrician.
Due to their technical training, knowledge and experience as well as their familiarity with rele-
vant standards and regulations, certified electricians are able to perform work on electrical
systems and independently detect possible dangers.
In Germany, certified electricians must fulfill the requirements of accident-prevention regu-
lations DGUV (German Social Accident Insurance) provision 3 (e.g. electrician foreman). In
other countries, there are respective regulations that must be observed.

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 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 338i. Detailed
explanations for the listed points can be found throughout the handbook.
3.1 Mounting the AMS 338 i
The AMS 338 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 338 i 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.

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 (18 … 30VDC). 2 freely programmable switching
inputs/outputs for individual adaptation to the respective application are also available here.
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.
Detailed information can be found in Chapter 8.
