Gotting HG 70661XA User manual

Transponder HG G-70661XA
Function
As the antenna passes over the transpon-
der, it energizes the latter with an energy
field of 13.56 MHz. The transponder returns
its code through frequency modulation to
the antenna. A normal reading cycle, in-
cluding all security checks, is approximate-
ly 1 ms.
The system’s operability is guaranteed
through fluid, gaseous as well as solid met-
al-free materials. However, if mounted di-
rectly on or within metal, the
transponder’s reading distance is
influenced.
The Read-Write Transponders are
equipped with an EEPROM in
which the code is stored. The EE-
PROM may be rewritten up to more
than 100,000 times. It has 32 bit
available for user data.
Dimensions and Specifications
The maximum reading distance for all tran-
sponders can only be achieved when the
minimum distance to the metal surface is
maintained.
It is recomended to maintain the minimum
distance within the metal-free area (figure
below). The impact on positioning accuracy
and range also depends on the size and the
distance of metal parts.
As a rule of thumb it can be said that if the
metal-free area behind the transponder has
to be at least of the same range as the read-
ing distance between transponder and an-
tenna. The reception of the transponder
signal will be largely unattenuated (see ta-
ble on right). It is essential, that the tran-
sponder does not dip into the mesh/loop
of steel reinforcement grids. Single metal
rods, on the other hand, hardly have any in-
fluence on the performence.

Mounting Instructions
Do not mount a transponder directly on
metal! The minimum distance around the
transponder as shown to the right should be
observed.
1 – On the Ground
The transponder has to be mounted on
even ground using a metal screw and a
washer. The maximum fastening torque is
not allowed to exceed 4 Nm. The diameter
of the metal washer should not extend
18 mm.
2 – In the Ground
The following equipment is required (not in-
cluded in the scope of supply):
-Rotary hammer drill
-Core bit (ø 85 mm)
-ø 8 to 10 mm drill bit
-hammer and chisel
-suitable sealing material
1. It is recommended that a test hole be
drilled prior to installing the transponder
network.
2. The position of the transponder should
be premarked and a centering hole
should be drilled with an appropriate
drill bit.
3. A hole may then be drilled with a
diameter of 85 mm to a depth of min.
50 mm (A). Any loose material must
be removed and the floor of the hole
has to be leveled out (B).
4. Afterwards fill the hole with sealing
compound up to a height of 40 mm
below the road (C). A delay may be
necessary before placing the tran-
sponder into position, dependent
upon type and viscosity of the seal-
ing compound.
5. The transponder is then to be placed
centered on the sealing compound
(C). Then fill the hole up with more
sealing compound.
