BATTERIES INSERTION
If battery powered the display switch off after 10 s if not used. In case of low battery it add this report. At the end of life cycle, process the included batteries according to the EU directive 2006/66 CE about the batteries, accumulators and relative wastes.

****200% not possible if Ir>50% In or Ir=OFF
For additional functions, as diagnostic test, advanced protection setting,
intervention curve visualization and report download, it’s necessary connect
via USB with PC (download software Power Control Station from e-catalog) or
with dongle-key bluetooth (0 283 10).
SERVICE SIGNALS
“Wait”:
It appears every time you change a threshold for intervention. The writing
is flashing and disappears after 4s last time you pressed a button control (+
/ -).
” Ok “:
It appears every time you store a new threshold for intervention. Setting and
navigation possible. Only navigation possible. The mechanical seal on
transparent cover does not prevent the setting by Software/app.

by Software PCS (refer to the user guide). Once the parameters have been set,
password is required. Parameters setting by Software or app disable a further
modification by buttons.
A further setting it’s allowed only by SW or app using the password.
In case of password loss, it’s possibile reset the protections to the factory
configuration following the user guide procedure.
