VEGA VEGALOG 571 CPU and carrier - Manual (Page 10)

4 Mounting
4.1 General instructions
The module cards of VEGALOG 571 can only be mounted into
the 19" carrier BGT LOG 571. It is provided with a special bus
board for data transmission between CPU and the individual
peripheral cards (LOGBUS). The carrier is designed for
mounting into a switching cabinet or 19" housing.
The plug position for the individual cards is individually
selectable, the system saves the card positions when switch-
ing on.
Note:
The plug positions must not be changed after the parameter
adjustment because measurement loops that have already
been set up would otherwise have to be reconfigured.
4.2 Carrier
By means of the plug connectors on the bus board, a fixed
pattern is created for the use of the modules. This ensures that
each module card is plugged into the multipoint connector and
also into its LOGBUS socket.

A VEGALOG 571 in the maximum configuration consists of
two completely equipped carriers which are connected to each
other via a pluggable bus cable (see "Chapter Electrical
connection"). Because the bus cable may not be lengthened,
the two carriers must be mounted directly above one another.
Note:
In the following cases, it is recommended to mount a 19"
ventilator to avoid a temperature increase in VEGALOG.
