Test function
Register 0 provides access to a test function,
which allows the output signals of the relay
module to be activated one by one. If the auxil-
iary relay module of the protection assembly is
in place, the auxiliary relays will operate one by
one during the testing.
Note!
The closing conditions of the circuit breaker are
not checked when the output signals of the test
function are activated (forced control).
When pressing the PROGRAM push-button
for about five seconds, the green digits to the
right of the display start flashing indicating that
the relay module is in the test position. The self-
supervision output is initially tested in the test
position. The indicators of the settings indicate
by flashing which output signal can be activated.
The required output function is selected by
pressing the PROGRAM push-button for about
one second.
The indicators of the setting quantities refer to
the following output signals:

The selected output signal is activated by simul-
taneous pressing of the push-buttons STEP and
PROGRAM. The signal remains activated as
long as the two push-buttons are pressed. The
effect on the output relays depends on the con-
figuration of the output relay matrix switches.
The self-supervision output is activated by press-
ing the STEP push button for 1 second when
no setting indicator is flashing. The IRF output
is activated in about 1 second after pressing of
the STEP push button.
The signals are selected in the order illustrated
in figure 13.
