Please be aware of the fact that also pickups from the overload protection or the
sensitive earth current supervision can cause and maintain a fault and therefore
block a close command. When resetting the interlocking also take into
consideration that the automatic reclosure lockout for motors in this case does not
automatically negate a close command sent to the motor. The automatic reclosure
must then be interlocked differently, e.g. via bay specific interlocking with CFC.
• Double operation: Parallel switching operations are blocked with respect to each
other: while one switching operation is being conducted, a second one cannot be
performed.
• Switching Authority – Local Commands: A local control switching command is only
allowed if local control is enabled on the relay (via lockswitch or setting).
• Switching Authority – Remote Commands: A remote control switching command is
only allowed if remote control is enabled on the relay (via lockswitch or setting).
Configuring a LED
Display as a
Destination
Single point indications (SP), output indications (OUT), and internal single point
indications (IntSP) may be assigned to LEDs. When this is done, you may select
whether the indications are to be latched (/) or unlatched (8).
Up to ten (10) indications may be assigned to a LED display. One indication may be
assigned to a maximum of ten (10) outputs (LEDs and output relays).
Configuring an
Indication Buffer
as a Destination
A maximum of three indication buffers may be available for messages: Operation
(Event Log) Buffer (2), Fault (Trip Log) Buffer (7) and Earth Fault Message Buffer (E).
The indications from protective functions are firmly assigned to these indication
buffers. For the others, Table 5-2 provides an overview of which indication type may
be configured to which buffer.
Select one of the following options for the named indication types:
• 2 (on or coming) – the indication is stored in the buffer with the time of its arrival
• 22 (on/off or coming/going) – the indication is stored in the buffer with the time of
its arrival and departure
• B (not configured) – the indication is not stored in a buffer.
