General information
1.3 Description of functions AMS 304i
The AMS 304i 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 304i
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.

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 304i
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 304i
The diameter of the light spot increases with distance.

Max. measurement distance
Light spot diameter ≤ 40mm ≤ 100mm ≤ 150mm ≤ 225 mm
Thus, the center-to-center spacing of the two AMS 304i 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 304i, it is necessary to distinguish
between three different arrangements of AMS 304i and reflectors.
40m 120m 200m 300m
The AMS 304i are mounted stationary and in parallel on one plane. Both reflectors move independently of one another at different distances to the AMS 304i.
Minimum parallel spacing X of the two laser light spots:
X = 100mm + (max. measurement distance in mm x 0.01)
The AMS 304i are mounted stationary and in parallel on one plane. Both reflectors move in parallel at the same distance to the AMS 304i.
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 304i Leuze electronic

Installation and mounting
The reflectors are mounted stationary and in parallel on one plane.
Both AMS 304i 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 304i 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 304i.
5.2.3 Parallel mounting of AMS 304i and DDLS optical data transmission
The optical data transceivers of the DDLS series and the AMS 304i 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 304i. The parallel spacing is independent
of the distance.

5.3 Mounting the AMS 304i 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 105.
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 304i 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 304i… 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 304i measures distances against a reflective tape specified by Leuze electronic.
All provided specifications for the AMS 304i, 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 304i 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 ea si ly be pulled of f. This mu st
be removed from the reflector before the complete system is put into operation.

6.2.4 Specifications of heated reflectors
The reflective tape is affixed to a heated, thermally insulated base. The insulation results in
a very high energetic efficiency.
Only the reflective tape is kept at the specified temperature by the integrated heater.
Through the insulation on the back, the generated heat cannot be transferred via the steel
construction. Energy costs are greatly reduced in the case of continuous heating.

or it can be mounted at a fixed location.
Attention!
The reflector sizes shown below are a recommendation from Leuze electronic for on-vehicle
mounting of the AMS 304i. For stationary mounting of the AMS 304i, a smaller reflector is
generally sufficient for all measurement distances.
On the basis of the system planning and design, always check whether mechanical travel
tolerances may require the use of a reflector larger than that which is recommended. This
applies, in particular, when the laser measurement system is mounted on a vehicle. During
travel, the laser beam must reach the reflector without interruption. For on-vehicle mounting
of the AMS 304i, the reflector size must accommodate any travel tolerances that may arise
and the associated "wandering" of the light spot on the reflector.

6.4 Mounting the reflector
6.4.1 General information
Self-adhesive reflective tapes
The reflective tapes of the "Reflective tape …x…-S" self-adhesive series must be affixed
to a flat, clean and grease-free surface. We recommend using a separate metal plate, which
is to be provided on-site.
As described in table 6.1, the reflective tape must be angled.
Reflective tapes on metal
The reflective tapes of the "Reflective tape …x…-M" series are provided with corresponding
mounting holes. Spacer sleeves are provided in the packet for achieving the necessary pitch
angle. For further information see table 6.1.
Heated reflectors
The reflective tapes of the "Reflective tape ...x...-H" series are provided with corresponding
mounting holes. Due to the voltage supply affixed on the rear, the reflector cannot be
mounted flat. Included in the package are four distance sleeves in two different lengths. Use
the distance sleeves to achieve a base separation to the wall as well as the necessary pitch
for avoiding surface reflection. For further information see table 6.1.
The reflector is provided with a 2m-long connection cable for supplying with 230V AC.
Connect the cable to the closest power outlet. Observe the current consumptions listed in
the specifications.
Reflectors
Attention!
Connection work must be carried out by a certified electrician.
6.4.2 Mounting the reflector
The combination of laser measurement system and reflective tape/reflector is mounted so
that the laser light spot hits the tape as centered as possible and without interruption.
For this purpose, use the alignment elements provided on the AMS 304i… (see chapter 5.2
"Mounting the AMS 304i"). If necessary, remove the protective foil from the reflector.
Attention!
The "TOP" label mounted on the reflectors should be aligned the same as the connections
of the AMS 304i.
Example:
If the AMS 304i is mounted so that the M12 connections are on the top, the "TOP" label of
the reflector is also on the top. If the AMS 304i is mounted so that the M12 connections are
on the side, the "TOP" label of the reflector is also on the side.

Notice!
The reflector must be angled. To do this, use the spacer sleeves. Angle the reflectors so that

spacers.

Reliable function of the AMS 304i and, thus, max. operating range and accuracy can only
be achieved with the reflective tape specified by Leuze electronic. No function can be guaranteed if other reflectors are used!

Press the ESC button twice to return to the Parameter menu.
Viewing and editing parameters
As long as parameter enabling is activated, the entire AMS 304i display is inverted.
As long as parameter enabling is activated, communication between control and AMS 304i
is interrupted. The continued networking via BUS OUT is retained.
Notice!
If a password was stored, parameter enabling is not possible until this password is entered,
see "Password for parameter enabling" below.
Notice!
Parameters which are defined in a GSD file have priority. After deactivation of parameter enabling on the AMS 304i, the parameter defined in the control are reactivated. The address
setting is not overwritten.
For the SSI interface, the communication between the control and the AMS 304i is also
active the case of parameter enabling.
Notice!
Changes to the SSI parameters via display entry have immediate effect.
Password for parameter enabling
Parameter entry on the AMS 304i can be protected with a password. With the AMS 304i,
the password is determined via the PROFIBUS GSD file. Thus, the password cannot be
changed by means of display entry.
To activate parameter enabling via the display (e.g., for changing an address), the password
defined in the GSD file must be entered. If parameter enabling has been activated after
successfully entering the password, parameters can temporarily be changed via the display.
After parameter enabling is deactivated, all changes made on the display are overwritten
by the GSD file. Even a possibly newly assigned password. Only a changed address remains
unchanged after entry via the display.
Notice!
The master password 2301 can enable the AMS 304i at any time.

9 PROFIBUS interface
9.1 General information on PROFIBUS
The AMS 304i is designed as a PROFIBUS DP device for cyclical (V0) as well as acyclic (V1)
data exchange.
For this purpose the functionality of the laser is defined via GSD parameter sets. The max.
baud rate of the data to be transferred is 12Mbit/s.
The PROFIBUS interface can be used parallel to the SSI interface. PROFIBUS and SSI
interfaces are activated by default.
Notice!
The PROFIBUS interface can be activated/deactivated via the display. To activate /
deactivate the interface, parameter enabling must be activated (see chapter 8.3.2). The
respectively active interface is shown in the display; when PROFIBUS is activated, the
address set is visible in the display.

Notice!
For contacting BUS IN and BUS OUT, we recommend our ready-made PROFIBUS cable
(see chapter 12.4.6 "Accessory ready-made cables for PROFIBUS").
Attention!
The laser measurement system can be used to branch out the PROFIBUS network. The
continuing network is connected via BUS OUT.
If the laser measurement system is the last subscriber in the network, the BUS OUT
connection must be connected to a terminator plug, see "Accessory terminating resistor"
on page 106..

9.3 PROFIBUS address entry
Notice!
Basic operation of the control panel/display is described in chapter 8.2. To set the address
parameter enabling must be activated. The display is inverted.
Attention!
The laser measurement system is deactivated on the PROFIBUS when parameter enabling
is activated via the display. The device is reactivated on the PROFIBUS after parameter
enabling is exited.
9.3.1 Entering the PROFIBUS addresses via the display
To do this proceed as follows:
Activate parameter enabling.
Select the PROFIBUS submenu.
Select the address menu item [ ].
Enter the PROFIBUS address of the laser measurement system; set to a value between
1 and 126 (default: 126).
Deactivate parameter enabling.
9.4 PROFIBUS GSD file
PROFIBUS interface
9.4.1 General information on the GSD file
If the AMS 304i is operated in a PROFIBUS network, configuration must be performed
exclusively via the PROFIBUS. The functionality of the laser measurement system is defined
via modules. The parameters and their functions are structured in the GSD file using module.
A user-specific configuration tool is used during PLC program creation to integrate the
required modules and configure them appropriately for the measurement application.
During operation of the laser measurement system on the PROFIBUS all parameters are set
to default values. If these parameters are not changed by the user, the device functions using
the default settings supplied by Leuze electronic. For the default settings of the device
please refer to the following module descriptions.
Notice!
At least one module in the GSD file must be activated in the configuration tool for the control,
usually the Position value module.
Leuze electronic AMS 304i 55
TNT 35/7-24V
Page 59
PROFIBUS interface
Notice!
Some controls make available a so-called "universal module". This module must not be
activated for the AMS 304i.
Attention!
The AMS 304i makes available a PROFIBUS and an SSI interface. Both interfaces can be
operated in parallel. If the AMS 304i is operated via the PROFIBUS, the SSI parameters must
also be changed via the PROFIBUS SSI module if they differ from the default settings.
SSI parameters which are only changed via the display are overwritten by the PROFIBUS
manager with the SSI (default) values stored in the GSD file.
Notice!
For test purposes parameters can be changed via the display on a laser measurement system
operated on the PROFIBUS. As soon as parameter enabling is activated on the display, the
device is deactivated on the PROFIBUS. All parameters set via PROFIBUS modules remain
effective. Parameter changes can now be made via the display for test purposes. If parameter
enabling is deactivated via the display, only the parameters set in the PROFIBUS modules
and the PROFIBUS default settings are in effect.
Parameter changes made via the display are no longer in effect on the PROFIBUS!
Attention!
The laser measurement system does not permanently store parameters changed via the
PROFIBUS. Following Power OFF/ON the currently configured parameters are downloaded
by the PROFIBUS manager. If no PROFIBUS manager is available following Power OFF/ON,
the parameters set on the display apply.
Notice!
All input and output modules described in this documentation are described from the
controller's perspective:
Described inputs (I) are inputs of the control.
Described outputs (O) are outputs of the control.
Described parameters (P) are parameters of the GSD file in the control.
Notice!

The parameters for sign, unit, resolution, count direction and offset remain adjustable.
Parameters
Parameter Description Rel.
Output mode of the sign.
Sign
Measurement unit
Resolution
Count
direction
Offset
Parameter length: 6 bytes
Sign affects position and velocity output.
Selection of the measurement unit
The parameter applies to all values with
measurement units. The parameter
applies to all interfaces.
Resolution of the position value applies
only to the PROFIBUS output. The resolution does not apply to:
- Static preset
- Dynamic preset
- Offset
The SSI interface has a separate parameter for the resolution.
Count direction positive:
0m
Counting direction negative:
0m
The parameter applies to all interfaces.
The count direction changes the sign
during velocity measurement.
For the SSI interface, no negative
position values can be transferred. In this
case, the value 0 is output at the SSI
interface.
A suitable offset is to be selected so that
only positive values are transferred.
Output value=measurement
value+offset.
The parameter applies to all interfaces.
Attention:
If the preset is activated, it has priority
over the offset. Preset and offset are not
offset against each other.
The resolution of the offset value is independent of the resolution selected in
module 1.
The entered offset applies immediately
without any further release.

Behavior of the AMS 304i on Laser ON/OFF:
If the laser light spot is positioned on the reflector when the laser diode is switched on, the
AMS 304i returns valid measurement values after approx. 330ms.
If the laser light spot is not positioned on the reflector when the laser diode is switched on,
the AMS 304i cannot calculate any distance values. If the laser beam hits the reflector at a
later point in time while switched-on, the AMS 304i 200 returns valid measurement values
after the following time span:
t = (measurement distance / 20m) sec.
Example: Corridor change of a high-bay storage device during which the laser diode
is not switched off while travelling around curves.
Measurement distance 100m –> t = 5sec., measurement distance

later point in time while switched-on, the AMS 304i returns valid measurement values after
the following time span:
t = (measurement distance / 20m) sec.
Example: Corridor change of a high-bay storage device during which the laser diode
is not switched off while travelling around curves.
Measurement distance 100m –> t = 5sec., measurement distance
200m –> t = 10sec.

9.4.3.10 Module 9: Error handling procedures
Description
The module makes parameters available to handle any errors should they occur.
In the event of a temporary error in the value/velocity calculation (e.g. plausibility error
caused by light beam interruption) the laser measurement system transmits the last valid
measurement value for a length of time xx which is to be configured.
If the configured time is exceeded, the error display or the faulty measurement value output
is activated.

Errors which occur are suppressed for
the configured time. If no valid position
value can be ascertained during the
configured time, the last valid position
value is output. If the error persists after
the time elapses, the value stored in the

9.4.3.11 Module 10: Velocity
Description
Outputs the current velocity with the configured resolution. The unit (metric or inch) is set
in module 1 (position value) and also applies to the velocity. If module 1 is not configured,
the AMS 304i operates with the default unit (metric).
The sign of the velocity is dependent on the count direction in module 1d.
In the default setting a positive velocity is output when the reflector moves away from the
AMS 304i. When the reflector moves towards the AMS 304i, negative velocities are output.
If the "negative" count direction is configured in module 1, the velocity signs are reversed.
Measurement value preparation averages all velocity values calculated during the selected
period to yield a velocity value.
Parameters

9.4.3.12 Module 11: Static velocity limit value 1
Description
The static velocity limit value 1 function compares the current velocity with a velocity
stored in the configuration. This occurs in the configured range, which is defined by range
start and range end.
Notice!
If range start and range end are identical, velocity monitoring is not activated.
If a direction-dependent limit value check is activated via the direction selection parameter,
the values of range start and range end also define the direction. The check is always
performed from range start to range end. For example, if the range start is "5500" and the
range end is "5000", the direction-dependent check is only performed in the direction from
"5500" to "5000". The limit value is not active in the opposite direction.
If the check is independent of direction, the order of range start and range end is irrelevant.
Depending on the selected switching mode, if the value is above or below the defined limits,
the limit value status in module 16 is set and, if configured, the output is appropriately set
via module 4 or 5.

9.4.3.18 Module 17: SSI interface
Description
The module defines the parameters for the SSI interface.
Attention!
The SSI interface can only represent posi tive distance values. If negative output values
are ascertained due to the offset or count direction, a zero value is output at the SSI
interface! In the event of a number overflow, all data bits are set to "1".
The unit, offset and count direction parameters of module 1 also apply to the SSI interface.
Notice!
If the SSI interface is not configured via module 17 (SSI interface) in PROFIBUS
operation, the SSI interface is deactivated.
If the SSI interface is operated without PROFIBUS (PROFIBUS OFF/SSI ON), configuration
is performed via the display.

9.4.3.21 Module 20: free resolution
Description
Free resolution is used when the resolutions set in the standard are not appropriate. If a free
resolution is used, it must be activated in module 10a.
Module 10a and module 1c must be set to configure the free resolution.
Parameters
Parameter Description Rel.
This module allows the output mea-
Free resolution position
Free resolution velocity
Parameter length: 4 bytes
surement values for position and velocity to be freely scaled.
The parameters apply to all interfaces
for which the “free resolution” resolution was selected. The internal measurement value is multiplied by the set
value on the basis of (mm/1000).
Example: Value “3000” means that in
the event of a change in the measurement value by 3 mm, the position value
in the binary code changes by binary 1.
Due to the free resolution in the example, an internal measurement value of
3333mm gives an output value of
“1111”.
The resolution of the “Offset", "Preset"
and "Limit values" parameters is not
affected by free resolution.

10 SSI
10.1 Principle functionality of the SSI interface
Data communication of the SSI interface is based on differential transmission as used for
RS 422 interfaces. Transmission of the position value, beginning with the MSB (most
significant bit), is thus synchronised with a clock cycle (CLOCK) specified by the control.
In the quiescent state both the clock line as well as the data line are at HIGH level. At the
first HIGH-LOW edge (point in figure 10.1) the data in the internal register are stored. Thus
it is ensured that the data cannot change during serial transmission.
When the next clock signal change from LOW to HIGH level (point in figure 10.1) occurs
transmission of the position value begins with the most significant bit (MSB). With each
successive change of the clock signal from LOW to HIGH level the next least-significant bit
is transmitted on the data line. After the least significant bit (LSB) has been output, the clock
signal switches from LOW to HIGH for one last time and the data line switches to LOW level
(end of transmission).
A monoflop retriggered by the clock signal determines the time span before the SSI interface
can be called for the next transmission. This results in the minimum pause time between
two successive clock cycles. If time tm = 20μs has elapsed, the data line is returned to the
quiescent level (HIGH) (point in figure 10.1). This signals completed data communication
and that the device is again ready for transmission.
Notice!
If the off-cycle of data transmission is interrupted for longer than t
will begin with a completely new transmission cycle with a newly calculated value.
If a new transmission cycle is started before time t
again.
has elapsed, the previous value is output

SSI
Attention!
The SSI interface can only represent positive distance values. I f negative output values
are ascertained due to the offset or count direction, a zero value is output at the SSI
interface! In the event of a number overflow, all data bits are set to "1".

Notice!
In the default setting the LSB bit is the error bit.
Attention!
Significance of the error bit:
By default a 25th error bit (LSB) is appended to the 24-bit measurement value.
The error bit is not included in the Gray coding of the measurement value.
The error bit is 1 = active, 0 = not active.
Notice!
The data can be read out with a clock rate between 80kHz and 800kHz.
Attention!
Updating the measurement values on the SSI interface of the AMS 304i:
The measurement value on the SSI interface of the AMS 304i is updated every 1.7ms
(default) independent of the clock frequency.
The update rate on the interface can be reduced to 0.2ms via the display under the SSI menu
item or in PROFIBUS module 17.
The shorter update rate is only valid for the SSI interface and has no influence on the
PROFIBUS DP interface.
