Signals
18 Technical Manual
Distributed busbar protection REB500
41845_PRP LineB ready
respectively (CIM module Ethernet ports LAN1 and LAN2). The
signal is active if a link has been established.
41415 BB zone blocked
Signals the blocking of BBP or the
inter
-
tripping system of a bus
zone. This signal is a combined signal i.e. both the blocking of BBP
and also blocking of the inter
-
tripping system are signaled.
Table 19 CU output signals for protection functionality
Signal Description
42305_BBP trip
BBP has tripped.
42310_BBP trip L0
A fault was detected on phase L0, L1, L2, or L3, respectively, and
BBP has tripped.
42315_BBP trip L1
42320_BBP trip L2
42325_BBP trip L3
42330_Check_Zone_Operated
The check zone
has operated.
42405_BBP blocked
BBP is blocked (either individual protection zones or the entire
system).
42805_ Check Zone Bypassed
The check
zone release function for BBP is bypassed.
42810_Check_Zone_Diff_Alarm
The differential currents of the check
zone exceed the set alarm
level.
43305_BFP trip t1
BFP tripped in time step 1.
43310_BFP trip t2
BFP tripped in time step 2.
43405_BFP blocked
BFP is blocked (either a bay unit or the entire system).
44305_EFP trip
EFP has tripped.
44405_EFP blocked
EFP is blocked (either a bay unit or the entire system).
45305_OCDT trip
OCDT has tripped.
45405_OCDT blocked
OCDT is blocked (either a bay unit or the entire system).
45805_OCDT start
One of the feeder time
-
overcurrent functions has picked up.
47305_P
DF Trip
Signals tripping by PDF.
47405_PDF blocked
PDF is blocked (either individual bays or the entire system).
48805_Voltage criterion
UV has been activated (either individual bays or throughout the
system).
49405_BP blocked
The outputs of the bay
protection functions are blocked (either
individual bays or throughout the system).
49410_BP partial blocked
Certain bay protection output signals in specific bays or throughout
the entire system are blocked (Must be configured together with the
corresponding BU output signal 29410_BP partial blocked).
The following signals (out of Table 18 and Table 19) can be used to trigger a
disturbance record in the central unit:
• 41815_Diff. current alarm
• 42305_BBP trip
