Field-signal connections M12 × 5 + FE
The UE4155 bus node has eight identical field-signal connections. However, field-signal
connections 7 and 8 also have fault monitoring in output Out A (see below).
The inputs of the field-signal connections are compatible with the Type-2 digital inputs
described in DIN EN 61 131
D

If you only use the outputs to provide electrical power (option
Output
= Static on), it is
permitted to switch channels A and B of a field-signal connection in parallel, in order to
double output power (switching pins 1 and 5 in parallel).
Take care when installing protected cables!
If an output serves several inputs, e.g. when connecting to an operating mode switch, the
cable that you install must be protected. There is otherwise a risk of a cross-circuit within a
cable that the bus node cannot detect in this case.

Connection of a muting lamp
Field-signal connections 7 and 8 also have fault monitoring in output Out A. This can be
used by the bus node e.g. to monitor a muting lamp. In the case of the wire being removed
or a missing connection, the bus node sets the status bit of corresponding input In A to
indicate an error. The error must then be evaluated in the FPLC.
Permissible lamps are, for example:
SICK display lamp (part no. 2017768)
SICK LED-muting lamp (part no. 2019909)
lamp 24 V/4 W
To activate fault monitoring, you must configure channel A of the field-signal connection
accordingly. Device symbol
