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

5.2 Mounting the AMS 338i
Figure 5.2: Mounting the device
The AMS 338i and the corresponding reflector are mounted on two mutually opposing,
plane-parallel, flat walls or system parts. For error-free position measurement, there must
be an unobstructed line-of-sight connection between the AMS 338i and the reflector.
Use M5 screws to fasten the laser measurement system. Secure the screws with a toothed
lock washer to protect against loosening caused by vibrations.
18 AMS 338i Leuze electronic
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.

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 338i
The diameter of the light spot increases with distance.

Installation and mounting
X
Max. measurement distance
Light spot diameter ≤ 40mm ≤ 100 mm ≤ 150 mm ≤ 225mm
Thus, the center-to-center spacing of the two AMS 338i 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 338i, it is necessary to distinguish
between three different arrangements of AMS 338i and reflectors.
40m 120m 200m 300m
The AMS 338i are mounted stationary and in parallel on one plane. Both reflectors move independently of one another at different distances to the AMS 338i.
Minimum parallel spacing X of the two laser light spots:
X = 100mm + (max. measurement distance in mm x 0.01)
The AMS 338i are mounted stationary and in parallel on one plane. Both reflectors move in parallel at the same distance to the AMS 338i.
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
Leuze electronic AMS 338i 21
TNT 35/7-24V
Installation and mounting
The reflectors are mounted stationary and in parallel on one plane.
Both AMS 338i move independently of one another at different or the same distances to the reflectors.
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
Notice!
Please note that when the AMS 338i 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 338i.
5.2.3 Parallel mounting of AMS 338i and DDLS optical data transmission
The optical data transceivers of the DDLS series and the AMS 338i 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 100 mm to the AMS 338i. The parallel spacing is independent
of the distance.

5.3 Mounting the AMS 338i 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 85.
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 338i 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 338i… 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.

6.1 General information
The AMS 338i measures distances against a reflective tape specified by Leuze electronic.
All provided specifications for the AMS 338i, 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 338i 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 35.
The reflective tapes are provided with a protective foil that can easily be pulled off. This must
be removed from the reflector before the complete system is put into operation.
