3.7 Coding
You can code the front sockets of the I/O modules and terminals so that the terminals and the
associated field devices can be assigned to exactly one front socket.
Use the KF-CP coding pins for the following terminal blocks: LB9007A, LB9009A, LB9013A ...
LB9019A, LB9107A, LB9107P, LB9113A, LB9115A ... LB9119A, LB9124A ... LB9127A,
LB9130A, LB9131A. Use the CP-MC 0.5 coding pins (Phoenix Contact order number
1881435) for the LB9130A and LB9131A terminal blocks.
Coding Connections
1. To code the front socket of an I/O module, insert one or more coding pins into the corre-
sponding grooves on the front socket.
2. In order to code the terminal to match the front socket, cut off the plastic lugs from the
terminal from those points where coding pins are located in the front socket.
Note that the coding in example 1 and example 2 is not unique. The terminal from example 1
could be accidentally connected to the front socket in example 2. In contrast, the coding in
example 1 and example 3 is unique.
3.8 Line Fault Detection
Most I/O modules have a line fault detection function that can recognize a lead breakage or a
short circuit.
If digital I/O modules are used, for example with a mechanical contact, an additional resistor
circuit must be installed to ensure that the line fault detection function can work correctly. Using
the additional resistor circuit, the electronics can distinguish between a closed switch and a
short circuit. See chapter 2.6.2
 LB1*03*
If you are using rotational direction detection, connect this input to a resistor circuit. The
rotational direction input is ignored for devices without rotational direction detection.
 LB1007*, LB1*08*, LB1*09*
24 V and 5 V inputs can only be used when line fault detection is disabled.
Caution!
Danger of incorrect connections
If the coding is not unique, terminals can be accidentally swapped.
Establish a unique coding so that every terminal fits exactly one front socket.
