Response after removing a component and powering up in the MANUAL mode
● Buffer modules are automatically commissioned.
● Expansion modules with an unchanged module position are activated with the last
operating state of the outputs before shutdown.
● For expansion modules with changed module position, 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.
Response after removing a component and powering up in the REMOTE mode
● Buffer modules with unchanged module position are automatically commissioned.
● Expansion modules with an unchanged module position are activated with the last
operating state of the outputs before shutdown.
● For modules with changed module position, the system response depends on the specific
case.
Case 1
The function of the module is identical with the function of the previous module at the
installation location (buffer module at the installation location of a buffer module, expansion
module at the installation location of an 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 identical 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.
