1.3 Description of functions AMS 348i
The AMS 348ioptical 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 348i
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 integration
time are designed for position control applications.
With the AMS 3xx i product series, Leuze electronic makes available a range of internationally
relevant interfaces. Note that each interface version listed below corresponds to a different
AMS 3xx

insurance association.
Attention!
The AMS 348i… is not a safety module acc. to EU machinery directives.
Qualified personnel
Mounting, commissioning and maintenance of the device must only be carried out by
qualified personnel. Electrical work must be carried out by a certified electrician.
Attention, laser radiation!
The AMS 348i operates with a red light laser of class 2 acc. to EN 60825-1. If you look
into the beam path over a longer time period, the retina of your eye may be damaged!
Never look directly into the beam path!
Do not point the laser beam of the AMS 348i at persons!
When mounting and aligning the AMS 348i, avoid reflections of the laser beam off of
reflective surfaces!
Heed the laser safety regulations according to DIN EN 60825-1 in their most current
version! The output power of the laser beam at the reading window is at most 4.0mW
acc. to EN 60825-1. The average laser power is less than 1mW in accordance with laser
class 2 as well as CDRH class 2.
The AMS 348iuses a laser diode with low power in the visible red light range with an
emitted wavelength of 650 … 690nm.
Attention!
CAUTION! The use of operating and adjusting devices other than those specified here
or carrying out of differing procedures may lead to dangerous exposure to radiation.

3 Fast commissioning / operating principle
Notice!
Below, you will find a short description for the initial commissioning of the AMS 348i.
Detailed explanations for the listed points can be found throughout the handbook.
3.1 Mounting the AMS 348i
The AMS 348iand 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 348iand the reflector.
3.1.1 Mounting the device
The laser is mounted on a vertical wall using 4 screws (M5).
Alignment is performed using 2 adjustment screws. Adjust so that the laser light spot is
positioned at the center of the reflector. The alignment is to be secured with the knurled nut
and locked with the M5 nut.
Further information can be found in chapter 5.2 and chapter 5.3.
3.1.2 Mounting the reflector
The reflector is mounted on a vertical wall with 4 screws (M5). The reflector is angled using
the included shims. Incline the reflector by approx. 1°.
Detailed information can be found in chapter 6.4.

Fast commissioning / operating principle
11 AMS 348iLeuze electronic
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.
3.4 AMS 348ion the PROFINET
Install the GSDML file associated with the AMS 348iin the PROFINET Manager of your
control. Activate the desired modules (at least one module).
The network address for PROFINET is assigned via the PROFINET Manager.
Standalone operation in PROFINET
During standalone operation of the AMS 348i, the PROFINET network is connected to
BUS IN. BUS OUT requires no terminating resistor.
Network operation in PROFINET
