5.1.1 External Parameter Memory
The external parameter memory is an optional supplement to the BCL. It is located in a plug cover and
consists of a permanent, rewritable memory (EEPROM). After being mounted, the two connections of
the BCL are under the plug cover in a common protection class IP 65. Figure 5.1 is a view of the plug
cover. Two pre-assembled connection cables that are permanently connected to the plug cover by PG
screw glands provide the BCL with unaltered signals.

The external parameter memory can only be operated with a BCL without heater. Various types are
available:

Function
When started, the BCL initialises itself with data stored in its internal parameter set. When a clone of
this parameter set is also kept ready at hand in an external memory, devices can be exchanged quick-
ly. The replacement device does not need to be manually configured first before operation, but auto-
matically accesses the external parameter memory by selecting the start option accordingly. It
downloads the parameter set stored in the parameter memory into its operating memory (RAM).
