5.5.5 Marshalling of the command (trip) relays --- address block 64
The unit contains 5 trip relays which are designated
TRIP RELAY 1 to TRIP RELAY 5. The trip relays can
be marshalled in the address block 64. The block is
reached by paging in blocks with Ý ß or by directly
addressing with DA, input of the address number
6 4 0 0 and pressing the enter key E. The selection
procedure is carried out as described in Section
5.5.1. Multiple commands are possible, i.e. one log-
ical command function can be given to several trip
relays (see also Section 5.5.1).
Principally, all annunciation functions in accordance
with Table 5.3, can be marshalled to output com-
mand relays.
The assignment of the trip relays as delivered from
factory is shown in the general diagrams in Appen-
dixA. The following boxesshow anexample formar-
shalling of trip relay 3. Table 5.6 shows all trip relays
as preset from the factory.
Important note: With single-pole trip it isimperative
that for each circuit breaker pole the corresponding
phase segregated command, e.g. ”BFP Trip L1”
(FNo 502) for pole L1, as also the three-pole com-
mand ”BFP Trip L123” (FNo 505) is marshalled
to the correct tripping relay. This is taken care of in
the presetting of the relay but must also be consid-
ered if the allocation of the trip relays is altered.
If several protection functions shall trip the same
breaker pole, each command relay must be trig-
gered by the corresponding command function.
Attention! The trip relays 1 and 2 are included in
the trip release concept of the protection device
(refer Section 4.2.7 for explanations). The alloca-
tion of these trip relays should not be changed
unless this concept is comprehensively clear,
and only in harmony with this concept.
