General information
1.3 Description of functions AMS 335i
The AMS 335i 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 335i
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 3xxi product series, Leuze electronic makes available a range of internationally relevant interfaces. Note that each interface version listed below corresponds to a
different AMS 3xxi model.

Fast commissioning / operating principle
3 Fast commissioning / operating principle
Notice!
Below, you will find a short description for the initial commissioning of the AMS 335i.
Detailed explanations for the listed points can be found throughout the handbook.
3.1 Mounting the AMS 335i
The AMS 335i 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 335i 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 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 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.
12 AMS 335i Leuze electronic
Fast commissioning / operating principle
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 connected interface, the network address must be configured via the display.
Detailed information can be found in chapter 8.
3.4 AMS 335i on the CANopen
Install the EDS file corresponding to the AMS 335i … in your planning tool/the control (e.g.,
TwinCAT).
Notice!
You can find the EDS file at www.leuze.com.
The AMS 335i is configured in the planning tool/control by means of the EDS file. If the
AMS 335i has been assigned an address in the planning tool, the address (Node ID) is to
be set on the AMS 335i via the control panel/display. Only if the addresses are the same
between the AMS 335i and the control can communication be established.
After all parameters have been set in the planning tool/control, the download to the
AMS 335i takes place. The set parameters are now stored on the AMS 335i.
Afterwards, all changed AMS 335i parameters should be stored in the control upon startup. This aids in retaining the parameters during device exchanges, as they a re now also
stored centrally in the control.
Each time a connection is established between the control and the AMS 335i, these parameters are now transferred again to the AMS 335i. Note that this function must be supported
by the control.
The CANopen baud rate is defined for the entire network in the planning tool/control.
The baud rate is set on the AMS 335i via the control panel/display.
Only if the baud rates are the same is communication with the AMS 335i possible.
Detailed information can be found in chapter 9.

Installation and mounting
Aligning the laser light spot in the center of the reflector
The laser light spot has to be aligned so that it always hits the center of the opposing
reflector, both at close range as well as at the maximum measurement distance. To align,
use the two M5 Allen screws ("A" in figure 5.2). When aligning please ensure that the
knurled nut and the lock nut ("B" in figure 5.2) are opened wide.
Attention!
To prevent the laser measurement system from moving out of alignment during continuous
operation, subsequently hand-tighten the knurled nut and counterlock with the nut with
WAF4 hexagon socket ("B" in figure 5.2). Knurled nut and nut must not be tightened until
alignment has been completed.
Attention!
The device must not be opened. Failure to comply will render the guarantee void. Warranted
features cannot be guaranteed after the device has been opened.

5.2.2 Parallel mounting of the AMS 335i
Definition of the term "parallel spacing"
As shown in figure 5.4, dimension X describes the "parallel spacing" of the inner edges of
the two laser light spots on the reflector.
Figure 5.4: Minimum parallel spacing X between adjacent AMS 335i
The diameter of the light spot increases with distance.
AMS 335i 40 (H) AMS 335i 120 (H) AMS 335i 200 (H) AMS 335i 300 (H)
Max. measurement distance
Light spot diameter ≤ 40mm ≤ 100mm ≤ 150mm ≤ 225 mm
Thus, the center-to-center spacing of the two AMS 335i devices with respect to one another
can be calculated as a function of the maximum measurement distance.
To define the minimum parallel spacing between two AMS 335i, it is necessary to distinguish
between three different arrangements of AMS 335i and reflectors.
40m 120m 200m 300m
The AMS 335i are mounted stationary and in parallel on one plane. Both reflectors move independently of one another at different distances to the AMS 335i.
Minimum parallel spacing X of the two laser light spots:
X = 100mm + (max. measurement distance in mm x 0.01)
The AMS 335i are mounted stationary and in parallel on one plane. Both reflectors move in parallel at the same distance to the AMS 335i.
Measurement distance up to 120m: minimum parallel spacing X ≥ 600mm
Measurement distance up to 200m: minimum parallel spacing X ≥ 750mm
Measurement distance up to 300m: minimum parallel spacing X ≥ 750mm
22 AMS 335i Leuze electronic
Installation and mounting
The reflectors are mounted stationary and in parallel on one plane.
Both AMS 335i move independently of one another at different or the same distances to the reflectors.
Measurement distance up to 120 m: minimum parallel spacing X ≥ 600 mm
Measurement distance up to 200 m: minimum parallel spacing X ≥ 750 mm
Measurement distance up to 300 m: minimum parallel spacing X ≥ 750 mm
Notice!
Please note that when the AMS 335i are mounted in a mobile manner, travel tolerances could
cause the two laser light spots to move towards each other.
Take the travel tolerances of the vehicle into account when defining the parallel spacing of
adjacent AMS 335i.
5.2.3 Parallel mounting of AMS 335i and DDLS optical data transmission
The optical data transceivers of the DDLS series and the AMS 335i do not interfere with one
another. Depending on the size of the used reflector, the DDLS can be mounted with a
minimum parallel spacing of 100mm to the AMS 335i. The parallel spacing is independent
of the distance.

5.3 Mounting the AMS 335i with laser beam deflector unit
General information
The two available deflector units are used for the 90° deflection of the laser beam,
see "Accessory deflector unit" on page 93.
Attention!
The deflector units are designed for a maximum range of 40m.
Longer distances on request.
5.3.1 Mounting the laser beam deflector unit With integrated mounting bracket
The AMS 335i is screwed onto the mechanism of the US AMS 01 deflector unit. The mirror
can be mounted for three deflection directions:
1. Upward beam deflection
2. Beam deflection to the left
3. Beam deflection to the right
The deflector unit is mounted on plane-parallel, flat walls or plant components. For errorfree position measurement, there must be an interruption-free line-of-sight between the
AMS 335i… and the deflection mirror as well as between the mirror and the reflector.
Use the M5 screws to mount the deflector unit. Secure the screws with a toothed lock
washer to protect against loosening caused by vibrations.

6 Reflectors
6.1 General information
The AMS 335i measures distances against a reflective tape specified by Leuze electronic.
All provided specifications for the AMS 335i, such as the operating range or accuracy, can
only be achieved with the reflective tape specified by Leuze electronic.
The reflective tapes are available as adhesive tapes, affixed to a metal plate and with an
integrated heater especially for use at low temperatures. Reflective tapes with heating have
the designation "Reflective tape …x…-H", where "H" is an abbreviation for the heating
variant.
The reflective tapes/reflectors must be ordered separately. The choice of size is left to the
user. In chapter 6.3, recommendations on reflector size are provided as a function of the
distance that is to be measured. In any case, the user must check to determine whether the
recommendation is suitable for the respective application.
6.2 Description of the reflective tape
The reflective tape consists of a white, microprism-based reflective material. The microprisms are protected with a highly transparent, hard protective layer.
Under certain circumstances, the protective layer may lead to surface reflections. The
surface reflections can be directed past the AMS 335i by positioning the reflective tape at
a slight incline. The inclination of the reflective tape/reflectors is described in chapter 6.4.2.
The required pitch can be found in table 6.1 "Reflector pitch resulting from spacer sleeves"
on page 36.
The reflective tapes are provided with a protective fo il that ca n easily be p ulled off . This mus t
be removed from the reflector before the complete system is put into operation.
