Language
When selecting the system language, make sure that:
- The protection release is in the local mode (if PR330/D-M is installed);
- the CB is open;
- Vaux 24Vdc and/or busbar voltage by means of PR330/V and/or PR030/B are present.
The protection release will not allow the language to be changed in the absence of one of the above conditions.
3.9.8.2.
Password
PPR332/P and PR333/P are supplied with the default password: 0001.
The password, which is required if all the changes to the protections or settings in the protection release are to be saved, can be
changed in the Settings-System-New Password menu.
The values that can be used in the password range from 0000 to 9999. The default password is given in par. 1.13.
To change the PW, first enter the old one, then select the 4 new figures: the value of each figure can be chosen with the UP and
DOWN keys. Use ENTER to confirm the figure and pass on to the next one.
The password is checked after the fourth figure has been entered. The procedure will change from the “READ” state to the “EDIT”
state if the password is correct.
The password prompt is disabled by setting the value of the password to [0000] (in the “System Configuration” menu). It is
therefore always possible to switch from “READ” to “EDIT”.
WARNING: The password is valid for up to two minutes from the last time a key was pressed. After that time, it
must be entered again so as to validate any changes or to access the menus.
