It is not possible to change the PSL using the IED’s front panel HMI.
Caution:
Where the installation needs application-specific PSL, the relevant .psl files,
must be transferred to the IED, for each and every setting group that will be
used. If you do not do this, the factory default PSL will still be resident. This
may have severe operational and safety consequences.
