You can use certain properly configured digital inputs to change the configuration of the
system without changing the programming parameters. In fact, the controller manages
internally four groups of alternative parameters that can be “copied” in the operating
parameters on request (through a dedicated digital input).
Alternative configurations can be programmed only using the BoardPrg3xx.
You cannot program or modify the configurations from the controller.
The parameters present in each alternative group are the following:

P.0101: Number of phases of the genset.

P.0102: Rated voltage of the genset.

P.0103: Generator rated frequency.

P.0104: Rated power of the genset.
It is possible to change the configuration by means the following input digital functions:

DIF.2151
– “Select configuration 1”. When the input becomes "active", parameters of
alternative configuration set 1 are copied in the working configuration.

DIF.2152
– “Select configuration 2”. When the input becomes "active", parameters of
alternative configuration set 2 are copied in the working configuration.

DIF.2153
– “Select configuration 3”. When the input becomes "active", parameters of
alternative configuration set 3 are copied in the working configuration.

DIF.2154
– “Select configuration 4”. When the input becomes "active", parameters of
alternative configuration set 4 are copied in the working configuration.
Remark: copying an alternative set in working configuration causes the loss of the previous
loaded parameters. The only way to restore them is to have them stored in another alternative
configuration and recall it.
Usually, this function is used with multiple-voltage and/or multiple-frequency panels: wiring the
cams of a selector to the panel on the inputs of the controller, you can manually switch voltages
and frequency without having to use the parameters of the controller.

The controller is equipped with a hardware clock.
