electrical connection
For the electrical connection of the BCL 301
i
, 3 connection variants are available.
The voltage supply (18 … 30VDC) is connected acc. to the connection type selected.
2 freely programmable switching inputs/outputs for individual adaptation to the respective application are
also available here. Detailed information on this topic can be found in Chapter 7.4.1.
7.3.1 MS 301 connector hood with 3 integrated M12 connectors
The MS 301 hood with integrated connectors features three M12 connector plugs and a Mini-B type USB
socket as a service interface. Parameter memory is integrated into the MS 301 which temporarily stores
the settings of the BCL 301
i
in the case of replacement and transmits them to a new device.
The address switch located in the MS 301 is used to set the multiNet address of the BCL 301
i
. If the
BCL 301
i
is the last participant on the multiNet bus cable, the BUS OUT socket on the MS 301 must be
fitted with a terminator plug (accessories).

7.3.2 MK 301 terminal hood with spring-cage terminals
The MK 301 terminal hood makes it possible to connect the BCL 301
i
directly and without additional
connectors. The MK 301 features three cable lead-throughs in which the shielding connection for the inter
-
face cable is also located. The BCL 301
i
is also to be configured when the MK 301 is in a closed state via
a Mini-B type USB socket functioning as the service interface. Parameter memory is integrated into the
MK 301 which temporarily stores the settings of the BCL 301
i
in the case of replacement and transmits
them to a new device. Address setting as well as termination of the multiNet is done in the interior of the
MK 301
NOTE
The shielding connection is done via the M12 connector housing.
NOTE
The integrated parameter memory for the simple replacement of the BCL 301
i
is located in the
MS 301.
NOTE
The bus is looped through the MS 301, i.e. the bus is not interrupted when the BCL 301
i
is
removed from the MS 301.
The bus is terminated at BUS OUT via an external mounted terminating resistor (see
chapter 13.5 "Accessory – Terminating resistor").
