Manual address allocation via operating unit keypad, stand alone
mode
With this form of address allocation a
with the evaluation unit is not
possible. This means that an address collision may occur later during operation. (Double
or multiple addressing).
Reconnect the operating unit to the operating voltage (12 V DC) (initialization). The RS-485 bus can
either be connected or not.
(1 or 2
) nd
OK (
The address can be overwritten as long as the operating unit has not been linked by the EU and the
operating voltage is not interrupted.
:
If the operating unit is connected at a later stage to the evaluating unit, the entered address
is transmitted together with the unique number of the operating unit to the EU and stored.

In the adjustment mode you can alter the transmission range between the operating unit and the
transponder. Note that the distance does not fall short of or exceed a minimum/maximum range
depending on the mounting surface.
Basically, the range should be adapted to a metal mounting surface. It is assumed that the maximum
possible transmission range is lower on a metallic surface than on a non-metallic surface.

Hold a IK2 / IK3 transponder at the required distance to the operating unit. The reading unit in the
operating unit alters the power of the electromagnetic field in stages (16 stages from max. to min.)
and checks at which power stage the transponder can still be read error-free. This cycle is repeated
twice. The value determined in this manner is stored non-volatile in the operating unit (until the next
adjustment) and can be used for future applications as a limit value for the maximum possible range.
This range adjustment is not highly precise. This mode serves primarily to ensure that the
operating unit operates correctly on a metallic mounting surface.
