BU 0700 GB-1411 Subject to technical alterations 49
3.2.5 BUS customer units
(SK CU1-USS, SK CU1-CAN/-RJ, SK CU1-PBR Option)
In addition to data connections, all Bus customer units also provide conventional
digital inputs and outputs.
By means of a relay contact, brake control and even warnings to another system
can be initiated.
The digital input has a 2.5V switching threshold for the evaluation of the
temperature sensor. The input can, however, also be used for an emergency stop
function.
All BUS switching components have the same basic design. However, the
Profibus Option has an RTS signal output on connector X6.3.83 in addition to the
data leads. In addition, the Profibus module also has a second set of data
connections (X6.4) and a DIP switch for the termination resistors at the front.
Note: Further details can be found in the applicable operating instructions for the
Bus systems,

Note: The BUS customer units include two SK8 shielding clips which can be used
to provide a better shielding connection of the bus cable to the shield angle of
the SK 700E.

WARNING / NOTE
It is not permissible to connect the output relay of the Customer Unit (SK CU...and SK XU) to dangerous
voltages(
≥60VAC) if a contact of the relay is connected to a circuit with safe isolation.
