When the unit is switched on by pressing the Read/On button, it is automatically in
the addressing mode and the connected slaves are displayed� If a different mode
was used before, press the MODE button until ADDR appears in the LC display
�
As an alternative you can change from any mode directly to the addressing mode
by keeping the MODE button pressed�
The Read/On button must then be pressed in order to detect the connected sla-
ves� If the addressing unit does not detect any slaves, error message F2 appears�
All detected slaves are indicated in the lower part of the display (small numbers)�
For conventional slaves neither the letter A nor B is displayed here� If new version
2�1 slaves are used, an A or B next to the address indicates whether this is an A
or B slave�
