Activation of setting group
The voltage need not be permanently present on one binary input. Any
pulse, which must be longer than 200 ms activates the corresponding set-
ting group. The group remains active until some other command, issued
either through one of the binary inputs or by other means (built-in MMI,
SMS, SCS), activates another group.
Only one input can be active at the same time. This means that the con-
tact, which determines an actual active group, must open before the con-
tact that activates a new setting group closes.

Configure the GRP--ACTGRPn input signals to the corresponding binary
inputs of a terminal and browse the built-in MMI for the information
about the active setting group under the menu:
Service Report
Active Group
Connect the appropriate dc voltage to the corresponding binary input of
the terminal and observe the information presented on the MMI unit. The
displayed information must always correspond to the activated input.
