1 Antenna configurations

The antenna installations described here are designed for reading Smart Labels

(transponders) on goods riding on conveyors, conveyor systems or pallets.

There must be no large magnetically conductive substances (e.g. metals) in the

vicinity of the antenna or label. The minimum distances to the individual compo-

nents are specified in the MOBY D manual for project planning, assembly and ser-

vicing.

1.1 Information for project planning

The antenna installation described below is suitable for detecting labels that move

horizontally through the installation. Depending on how the antennas are installed

(either directly across from each other or offset in parallel), the labels either must

be oriented parallel to the antennas or can have any orientation.

The size of the detection range depends on the label orientation.

Attention

Note that the overall detection range of the antenna is larger than the configured

detection range. Thus, certain label orientations make it possible to detect labels

outside of the detection range. For example, labels that are parallel to the anten-

nas can be detected at large distances next to or beyond the antennas.

For this reason, goods should not be stored outside of the detection range within

0.5 m of the installation. If this distance cannot be maintained, the antennas must

be shielded.

The following points must be noted to ensure three-dimensional detection of labels

within the detection range:

SThe gate width should be less than or equal to 800 mm.

SThe labels should be no smaller than an ISO card (46 mm x 75 mm).

SThe distance from label to label should be greater than 100 mm.

The distance from label to label can be reduced by narrowing the gate width

accordingly. In particular, this applies to distances below 50 mm.

SThere should be no more than 16 labels within the antenna detection range at

any one time.

The number of labels can be increased by narrowing the gate width and adju-

sting the maximum speed accordingly.

SThe maximum label speed should not exceed 1 m/s. (This value is a function of

the number of labels, label orientation, the number of data blocks, the data re-

port required and the label type).

SAny metal parts should be at least 150 mm from the sides and front of the an-

tenna.

SThe read/write unit should not be subject to interference from other electrical

devices in the area. The difference between noise levels should be less than

20 mV.

Note

The SLG D10S does not have multitag capability.

Installation instructions

Each of the cables on the antennas and antenna duplexer is 3.3 m in length. The-

refore, the read/write unit must be mounted near the antennas. If there is a large

distance between the read/write unit and the antennas, the antenna cable can be

lengthened by 7.2 m using the extension cable (6GT2 691-0DH72). However, this

leads to slight output losses.

1.3 Metal-free area

To ensure that the various installation variants operate correctly, any large metal

parts in the vicinity of the antennas must be removed.

J31069-D0158-U001-A0-7618

If metal parts in the vicinity of the antenna cannot be avoided, note the follo-

wing:

SA minimum distance of 100 mm should be maintained between the antenna and

metal parts in all directions. At 50 mm and beyond, the read range will be

greatly impaired. At distances to metal of 150 mm and beyond, there are on

measurable losses.

SThe degree to which metal parts will have an effect is greatly dependent on

their size and shape. Thin metal poles have less influence on magnetic field

lines than do large surfaces.

SLarge metal surfaces (edge lengths > 50 mm) that are parallel to the antennas

or labels will cause the magnetic field lines to short circuit. This will make it im-

possible to read the labels.

SAny metal parts beneath the conveyor will alter the path of the magnetic field

lines. This will greatly impair the read range. It will be impossible to read labels

with a horizontal orientation.

SMetal parts should not form closed loops or electrical circuits. If neces-

sary, they should be disconnected at a suitable location.

SAny metal parts in the immediate vicinity of the antenna must be grounded with

a good HF connection using a star ground circuit.

SBecause the read/write unit is installed in a metal housing and the antennas can

be coupled to the cables of the read/write unit, the unit should be mounted at

least 500 mm from the antennas.

1.4 Information on mounting and laying the antenna cables

To suppress interference, an EMC snap ferrite must be installed on each antenna

cable (including on the antenna cable between the SLG and the antenna duplexer).

The coaxial cable must be passed through the EMC core at last four times in tight-

fitting loops. The distance between the ring core and the connector to the read/

write unit or antenna duplexer should not exceed 100 mm.

The antenna cable should always be vertical when leading away from the anten-

nas. The cable should be laid at least 200 mm from the antennas.

There will otherwise be a loss in output.

All antenna cables must be laid at least 300 mm from parallel live cables.

Unused cable length must be wound into a coil of ∅ = 100 to 150 mm.

If the standard antenna cable is too short, it can be lengthened by 7.20 m using the

extension cable. This will lead to slight losses in range.

To achieve the best possible read ranges, the antenna cable should not be shorte-

ned or extended.

2 Installation startup and testing performed by trained per-

sonnel

After the antennas are mounted and balanced, the system can be checked to en-

sure it is functioning properly using a read/write unit, the MOBY D SET service

software, a PC with the MS Windows operating system and a Smart Label.

4Target values:

Average: 500 to 700 mV

Vmax – Vmin < 20 mV

If the target values have not been met, check the following:

SAre all cables well connected and do they make good contact?

SHave the ring cores been installed on the antenna cables?

SWere the cables laid as required?

SHave other RF identification systems been installed nearby?

SAre there any large metal parts near the antenna?

SAre there any devices nearby that may emit interference (large machines or

radio equipment)?

To determine which devices may interfere with the operation of a gate, discon-

nect them briefly from the mains.

J31069-D0158-U001-A0-7618

2.3 Testing the performance

To test performance, start the ISO Inventory command in the MOBY D SET pro-

gram.

If labels are parallel to the antenna, a continuous read field will be present between

the two antennas. This should be tested for all antenna pairs.

All labels with this orientation are read when they move horizontally through the

antenna field.

If opposite antennas are offset from each other and labels are perpendicular to the

antennas, the label should be detected when moving in the direction of passage

through the system. The length of this detection range equals roughly half the an-

tenna width (depends on antenna type).

The following errors may occur:

SAntenna is incorrectly mounted (orientation, distance between antennas, ca-

bling)

SAny metal nearby will detune the antennas or cause interfere

SNoise level too high (Vmax – Vmin ≥ 20 mV) due to external interference (e. g.

from monitors, motors, converters)

SLabel is detuned (due to metal) or defective

SRead/write unit is incorrectly configured (transmitting power, transponder type,

modulation, transponder parameters, etc.)

SA cable is defective or is making poor contact

SRead/write unit, antenna range or antenna is defective
