2. SETTING FAMILIARISATION
When commissioning a MiCOM P440 relay for the first time, sufficient time should be
allowed to become familiar with the method by which the settings are applied.
Chapter P44x/EN IT contains a detailed description of the menu structure of the relays.
With the secondary front cover in place all keys except the [Enter] key are accessible. All
menu cells can be read. LEDs and alarms can be reset. However, no protection or
configuration settings can be changed, or fault and event records cleared.
Removing the secondary front cover allows access to all keys so that settings can be
changed, LEDs and alarms reset, and fault and event records cleared. However, menu cells
that have access levels higher than the default level will require the appropriate password to
be entered before changes can be made.
Alternatively, if a portable PC is available together with suitable setting software (such as
MiCOM S1), the menu can be viewed a page at a time to display a full column of data and
text. This PC software also allows settings to be entered more easily, saved to a file on disk
for future reference or printed to produce a setting record. Refer to the PC software user
manual for details. If the software is being used for the first time, allow sufficient time to
become familiar with its operation.
