BCU 580 · Edition 11.15l 6
Application
Using the BCSoft program, the parameters, analysis 
and diagnostic information can be read from a BCU 
via the optionally available opto-adapter. All valid 
parameters are saved on an integrated parameter chip 
card. The parameter chip card can be removed from 
the old unit and inserted into a new BCU to transfer the 
parameters, for example when replacing the unit.
The monitored outputs for the actuator and valves are 
accommodated in a plug-in power module. This can 
simply be replaced if necessary.
Once the plug-in power module has been removed, the param-
eter chip card and fuses are accessible.
The BCU can be installed on a DIN rail in the control 
cabinet. Plug-in connection terminal strips on the BCU 
make it easier to install and remove.
Thanks to the operator-control unit OCU, display functions and 
operation of the BCU can be relocated to the control cabinet 
door.
