BU output signals for disturbance recorder (DR)
BU output signals for voltage release (UV)
Description
The voltage release criterion of this bay unit is fulfilled (measuring voltage
is below the setting of the voltage criterion).
BU output signals for bay protection (BP) (REB500sys only)
Description
The outputs of the bay protection functions are blocked (either the bay
concerned or throughout the system).
Certain bay protection functions are blocked (Signal must be set explicitly
by the bay protection).
Parameter set 1, 2, 3, or 4, respectively, is active. This can take place via the
station bus or an input signal.
In addition to the bay protection output signals listed above, which are
always available, use can also be made of the signals configured for the
binary signal output block of the bay protection. The number of these
signals depends on the protection functions and signals included in the
bay protection.
