5.2 Exchange LB 44x to LB 47x
NOTICE

If you install a DuoSeries LB 47x transmitter, in order to replace a LB 44x, it is
necessary to consider an incompatibility in the connecting terminals.

In the most unfavorable case a short circuit in the connected terminals
can happen!

Consider the following information.
When using the terminal blocks, the most important electrical connections are
identical (detector connection, current output, voltage supply). Other terminals
like the I/O connections are not compatible.
The following figure shows the terminal assignments of the DuoSeries LB 47x.
Green: Identical connections LB 44x / DuoSeries LB 47x
Red: Changed clamp assignment DuoSeries LB 47x in comparison to LB 44x
