Case 1
Replacement using a module with the same function (a buffer module by buffer module,
expansion module by expansion module):
● A compatibility check is carried out for buffer modules:
–
If a buffer module with electrolytic capacitors is replaced by a buffer module with
electrolytic capacitors, then the new module is automatically commissioned.
– If a buffer module with double-layer capacitors is replaced by a buffer module with
double-layer capacitors, then a more powerful module is automatically commissioned.
A module with a lower power rating is deactivated (LED "OK" flashes red). You can
activate this module by loading a corrected configuration via the associated control
system.
– If a buffer module with electrolytic capacitors is replaced by a buffer module with
double-layer capacitors - or vice versa - then the new module is automatically
deactivated ("OK" LED flashes red). You can activate this module by loading a
corrected configuration via the associated control system.
● For expansion modules, a compatibility check is carried out:
–
For expansion modules with a higher power rating, after switching on again, the
outputs are in the operating state "manually shutdown" (the LEDs of the outputs are lit
yellow).
The outputs are switched-on by pressing their associated buttons.
– Expansion modules with a lower power rating are deactivated (LED "OK" flashes red,
LEDs of the outputs are dark).
You can activate these modules by loading a corrected configuration via the
associated control system.
Case 2
Replacement using a module with a different function (a buffer module by an expansion
module, or vice versa):
● The new module is deactivated (LED "OK" flashes red, LEDs of the expansion module
outputs are dark).
You can activate the module by loading a correct configuration via the associated control
system.
