Overheating protection of the filter
By default, the BDCL filter is protected against overheating (caused by a faulty fan, for
example) with a thermistor and the temperature monitoring function of the control program.
If the filter temperature becomes too high, the temperature monitoring function stops the
DC/DC converter module automatically.
BCU control unit of frame R8i and multiples
Frame R8i (and multiples, if any) modules are controlled by a single BCU control unit installed
separately from the module(s). The control unit is connected to each module by a fiber optic
link. The control unit can be powered from the module (terminal block X53), from an external
24 V DC supply, or both for redundancy. The control unit contains the basic I/Os and slots
for optional I/O modules. Other equipment is primarily installed on separate mounting plates.
