– 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 ("O.K." 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 switched off" (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 "O.K." flashes red,
LEDs of the outputs are dark).
You can activate these modules by loading a corrected configuration via the
associated control system.
Replacement using a module with a different function (buffer module by an expansion
module or UPS module - or vice versa):
● The new module is deactivated (LED "O.K." 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.
