Electrical connection
Example 2
You want to set address 27.
16 + 8 + 2 + 1 = 27
You must set the DIP switches
5 = 16
4 = 8
2 = 2
1 = 1
to „ON“.
Example 3
You want to set address 99
64 + 32 + 2 + 1 = 99
You must set the DIP switches
7 = 64
6 = 32
2 = 2
1 = 1
to „ON.
Software addressing
The DIP switches must be set to an address
of 126 … 255, i.e.
- either all DIP switches are set to „ON“,
which corresponds to address 255 (deliv-
ery status)
ON Addr.
8 7 6 5 4 3 2 1
OFF
1
2
4
8 16
32
64
128
8 7 6 5 4 3 2 1
- or only DIP switch 8 is set to „ON“, which
corresponds to address 128.
Of course, software addressing is also pos-
sible, if the switches 7 … 2 are set to „ON“
(address 126).
The setting of the address with the software
VVO is described in chapter “5.2 Adjustment
with VVO” under the heading “Software ad-
dressing” or in chapter “5.3 Sensor adjust-
ment with the adjustment module MINICOM”.
