7.4 "CONFIG SELECT" sub-menu (only for MiCOM P922 and P923)
This menu allows the user to select the active setting group (1or 2). By default, the
active setting group is “GROUP 1”.
A digital input configured “CHANG SET” can operate either on edge or on level.
When the user chooses the “LEVEL”, then the change of setting group is only
authorized by a logic input (no possibility to change the group neither from rear port
nor from front panel).
With this mode (LEVEL) and when the digital input is configured on high level (see
“CONFIGURATION” menu/”CONFIGURATION INPUTS” § 7.6) so we have :
low level = GROUP 1
high level = GROUP 2
If the user wants to change the setting group with either remote command or from
front panel, he must choose to operate with “EDGE” mode.
Starting from firmware Version 4, the Active Group will be displayed (read mode
only) in the "OP PARAMETER" menu.
The change of the active setting group can also be done via a remote command
through the communication link (refer to chapter 6 of this Technical Guide).
To gain access to the “CONFIG SELECT” menu from the default display, press 2
once, 6 once, 2 once and 6 3 times.
