Section 2 Safety information
GUID-7CDA9FB7-5CD6-4BD5-A1D2-AAB8E7BF87A3 v2
Dangerous voltages can occur on the connectors, even though the auxiliary
voltage has been disconnected.
Non-observance can result in death, personal injury or substantial property
damage.
Only a competent electrician is allowed to carry out the electrical installation.
National and local electrical safety regulations must always be followed.
The frame of the IEDs has to be carefully earthed.
Whenever changes are made in the IEDs, measures should be taken to avoid
inadvertent tripping.
The IEDs contain components which are sensitive to electrostatic discharge.
Unnecessary touching of electronic components must therefore be avoided.

Signal Description
11105_External TRIP Tripping command received from another protection
device(including one in the remote station) and used for the
REB500 tripping contact to trip faults on a line or a power
transformer.
11110_External TRIP BB zone Used when an external signal has to trip the entire bus zone to
which the feeder is connected (for example, an external BFP signal).
Applied to all the bay units of the bus zone and sections of busbars
interconnected by an isolator (intertripping).
11115_Ext_Test_TRIP Activates the signal 21120_EXT_TEST_TRIP to operate several
tripping relays simultaneously.

Technical manual

Signal Description
11120_BP External TRIP Tripping signal generated by the feeder protection part. Trips faults
on a line or power transformer with the aid of the REB500 tripping
contact. Tripping thus takes account of the busbar configuration at
the time.
To function correctly, the signal has to be assigned to a feeder.
The simplest arrangement corresponds to the assignment of the
signal 11105_Ext. TRIP to feeders. If signal 11105_Ext. TRIP is not
available, a binary output has to be configured for 11120_BP
External TRIP which is then assigned to a feeder. The signal is
activated by the feeder protection directly and does not therefore
appear as binary input signal.
11125_BP External TRIP BB zone This is a tripping signal generated by the feeder protection part
which is used to trip the entire bus zone to which the feeder is
connected. The tripping command is applied to all the bay units of
the bus zone and sections of busbars interconnected by an isolator
(intertripping).
11205_Block SP A signal applied to this input blocks the local station protection
functions (BFP, EFP, OCDT and PDF), External Trip, tripping by the
busbar protection and intertripping of the respective bay unit. The
Bus Bar Protection continues to be active as a system function. The
primary injection of the concerned bay unit can lead to a trip of the
respective zone.
11210_Block output relays All the output contacts configured for a bay unit are blocked.
11215_Ext. measuring disturbed This signal is active when invalid analogue values are received from
an external device. The busbar protection (that is, the specific
protection zone of the busbar) and all the local protection functions
are blocked. If the disturbance lasts longer than 400 ms, diagnostic
events are generated (BBP Minor Error 9 and BBP Minor Error 20).
This input should only be used in special cases and only when
engineering a REB500 system.
11505_Close command CB The circuit-breaker close command is needed by the busbar and end
fault protection in bus-tie breaker and configured feeder bay units
to control the REB500 measuring system.
11510...11525_Supervision aux.
voltage_x
The supervision of the auxiliary supply is configured when the
compliance of the auxiliary contacts on the isolators with the
required switching sequence cannot be guaranteed and for this
reason the Not OPEN = CLOSED logic has to be used. These signals
ensure that the protection responds correctly should the auxiliary
supply to the isolators fail.
This signal is only applicable in the case of Not OPEN = CLOSED.
The supervision signals affect all switchgear objects or associated
with this BU independent of the respective supervision voltage
levels.
11530_Isolator/Breaker Position The position of a circuit-breaker or an isolator is signaled by one or
two auxiliary contacts.
11605_External release Trip Providing they have been configured, a signal applied to this input
enables tripping by the busbar protection and the intertripping
function in the bay unit (AND logic of tripping and enabling signals).
The input has no influence on other protection functions. This input
can be used in special cases to interlock tripping by the protection
by, for example, an external undervoltage relay.
11610_External reset Tripping commands and signals can be configured to latch after
picking up, in which case they must be reset by applying a signal to
this input.
It also resets the text display and LED’s on the local control unit. A
reset signal resets the entire system.

Signal Description
11615, 11625, 11635,
11645_Inspection_x-Off
These inspection inputs (x = 1 to 4) activate the isolator or circuit-
breaker inspection mode for the cases 1 to 4.
As with the isolator inputs for the busbar image, two anti-
coincident signals can be connected to these inputs. If the status of
both inputs is identical, this is interpreted as an error. The last valid
position is maintained and the LHMI on the bay unit indicates the
error message Insp. Alarm x (x= 1 to 4 corresponding to the number
of the inspection input).
These signals are only used when anticoincidence supervision of the
inspection inputs is specified. The signal pairs in Table 6 result in
relation to the inspection cases.
11620, 11630, 11640,
11650_Inspection_x-On
These inspection inputs (x = 1 to 4) activate the isolator or circuit-
breaker inspection mode. They are only used both in cases where
there is only one inspection signal (without anticoincidence
supervision) and where there are anticoincidence signals (with
anticoincidence supervision) (see Table 6).
11655_Maintenance-Off Anti-coincident maintenance input. Refer to the description for the
Inspection_x-Off signals. If the status of both inputs is identical,
the LHMI on the bay unit indicates MaintenanceAlarm.
11660_Maintenance-On This input is excited by the maintenance function. It is used should
only one maintenance signal be available.
11765_General Start DR This signal shall be configured in the bay unit and defined as a DR
trigger, so that the DR function of the bay unit is basically able to be
started by the following input signals for General Start of the DR:
•36705_General Start DR
•16750_Start DR_10 or 16760_BP General Start DR
Without this signal, the bay unit will not respond to a General Start
DR .
This signal is used during General Starting as
system internal link between General Start input-
signals and the DR function. It may not be
configured onto an optocoupler input. This is
achieved by setting the HMI500 menu item
Configuration/Binary Module/Inputs/Details/
Contact mode to No auxiliary contact.
11840…11885_GP_In_x With a properly configured event configuration, the input signal can
be transmitted via LON or IEC103 and displayed on the control
system. It is also possible to display the state of the signal on the
local HMI LED’s of the bay unit.

Table 7: BU input signals for BFP, EFP, OCDT, and PDF
Signal Description
12605_Bypass Check Zone The check zone criterion for the release of the bus bar protection is
bypassed.
13205_Block BFP Blocks operation of BFP for the corresponding bay unit. When the
blocking signal is cancelled, the timers start again at t = 0.
13210_BP Block BFP Blocks operation of BFP of the corresponding feeder. When the blocking
signal is cancelled and providing a starting signal is present and current is
flowing, the timers start again at t = 0.
13605_Trip redirection _1 The circuit-breaker sets this input when it cannot open, that is because
the air pressure is too low or there is a leak in the case of GIS (Alarm Stage
3 - Circuit-breaker blocked). A tripping signal is then transferred to the
adjacent breakers (busbar trip) and possibly the remote station.
13606_Trip redirection_2 Reserved for special applications.
If this signal is set then the trip redirection is active in the same way as it
is for the 13605_Trip redirection _1.
This signal must not be used for pressure low input from circuit-breaker.
13610_BP Trip transfer Reserved for special applications.
This Bay Protection (BP) signal allows triggering the trip redirection
functionality if the signal 13605_Trip redirection _1 or 13606_Trip
redirection_2 is active.
This signal is directly activated by BP and does not therefore appear as a
binary input signal.
13705_External Start BFP A signal applied to this input starts the breaker failure protection timer
(independently of the overcurrent measurement).
13710...13735_Start BFP Lp_x Phase-selective (p = 1 to 3) starting of the breaker failure protection with
two inputs per phase (x = 1 to 2). The breaker failure timer is started by
this input signal providing the current in the respective phase is above
pick-up.
13740...13765_Start BFP
L1L2L3_x
Three-phase starting of BFP by six inputs (x = 1 to 6). The BFP timer is
started by a signal at one of these inputs providing the current in at least
one phase is high enough.
13761_BP Start BFP L1L2L3_5 Functionally identical to signal 13760_Start BFP L1L2L3_5 but directly
activated by the bay protection unit and not appearing as binary input
signal.
13770...13780_BP Start BFP Lp BFP with phase-selective starting (p = 1, 2, or 3). The BFP timer starts
when this signal is activated by the bay protection function and the BFP
measures a current in the corresponding phase.
13785_BP Start BFP L1L2L3 BFP with three-phase starting. The BFP timer starts when this signal is
activated and the BFP measures a current in any phase.
13790_BP External start BFP BFP with three-phase starting. The BFP timer starts when this signal is
activated regardless of the current measurement.
13795...13796_Start BFP L0_x L0-starting of BFP with two inputs (x = 1 or 2). The BFP timer is started by
this input signal providing the current in the neutral system is above pick-
up.
13797_BP Start BFP L0 Breaker failure protection with L0 - starting. The breaker failure
protection timer starts when this signal is activated by the bay protection
function and the BFP measures a current in the neutral system.
13805_Start BFP Q0 no I_1
13810_Start BFP Q0 no I_2
The BFP timer starts when this signal is activated and the Breaker
(11530_Breaker Position) is closed and valid (independently of the
overcurrent measurement).
14205_Block EFP Blocks operation of EFP for corresponding bay unit. When the blocking
signal is cancelled, the timers start again at t = 0.
14405_BP EFP Manual Close This signal is set by the bay protection when the circuit-breaker receives a
close command to prevent EFP from tripping.
14605_EFP ext release_1
14610_EFP ext release_2
Providing this input is configured, EFP is enabled by an external signal.

Table 8: BU input signals for disturbance recorder (DR)
Signal Description
16705...16750_Start DR_x The disturbance recorder function is started by an external signal applied
to one of these 10 inputs (x = 1 to 10), or they can be simply used for
recording purposes. The external signal may come, for example, from the
tripping contact of a bay protection relay or the starting contact of a
time-overcurrent relay. Optocouplers are configured for these inputs.
The signal 16750_Start DR_10 is also transferred to the central unit where
it initiates the General Start (of all disturbance recorders with
appropriate configuration).
To ensure this functionality, the following additional signals must be
configured and defined as a trigger under the DR:
• For the start of the DR of the central unit the CU output signal
46705_DR general started
• For the start of the DR of the bay units the BU input signal
11765_General Start DR
16760_BP General Start DR This signal is used to start all appropriately configured disturbance
recorders in the system (General start disturbance recorder). To ensure
this functionality, the following additional signals must be configured and
defined as a trigger under the DR:
• For the start of the DR of the central unit the CU output signal
46705_DR general started
• For the start of the DR of the bay units the BU input signal
11765_General Start DR
This signal is directly activated by the bay protection
unit and does not therefore appear as a binary input
signal.

Signal Description
19205_Block BP Blocks the protection output signals of the respective bay unit. Internal
processing of the functions continues and therefore measurements and
signals continue to be displayed on the local HMI.
19600_Activation BP ParSet_1 The protection functions and settings assigned to parameter set 1, 2, 3, or
4, respectively, are active. They remain active after the signal has been
reset.

In addition to the bay protection input signals in this table, which are
always available, use can also be made of the signals configured for the
binary signal input block of the bay protection. The number of these
signals depends on the protection functions and signals included in the
bay protection.

GUID-0A2887D5-4FDF-44CE-B2D4-B9E196CCD6C2 v2
Table 11: BU general output signals
Signal Description
21105_EXTERNAL TRIP Tripping command generated by the external input 11105_EXTERNAL
TRIP.
21110_TRIP Tripping command generated by the station protection intertripping
function (BBP, BFP t2 etc).
21115_REMOTE TRIP Any of the protection functions that are capable of tripping an entire
section of busbar (intertripping) can initiate a remote trip signal.
Protection functions of this kind are: BBP, BFP, EFP, or the command
EXTERNAL TRIP.
Remote tripping can only take place if a fault cannot be cleared by the
circuit-breaker in the bay concerned. This applies in the following cases:
• 1½ breaker schemes
• Bypass operation with the bus tie breaker being used for a feeder
• Circuit-breaker bypassed by an isolator
• Feeder not equipped with an own circuit-breaker
More details on special application cases are given in the
Application
Manual
.
21120_EXT_TEST_TRIP Generates a multi-pole trip for test purposes. Either controlled by the
binary input signal 11115_Ext_Test_TRIP, or by the LHMI Test Trip menu.
If both, the 11115_Ext_Test_TRIP and LHMI Test Trip function are
configured and used simultaneously, 21120_EXT_TEST_TRIP results in an
OR function of both possible inputs.
Please refer to
Operation Manual for further information about the LHMI
Test Trip function.
21125_TRIP Combined general tripping command summarizes the general tripping
commands of station protection and bay protection functions (if
existing). For details about combined tripping commands see Section 3.7.
21130_TRIP L1 Combined tripping command summarizes the phase L1 tripping
commands of station protection and bay protection functions (if

is operational and standing by.
21810_Loss of supply voltage This signals a failure of the isolator auxiliary supply (Supervision aux.
voltage_x) in the bay unit.
21815_Inspection/maintenance This signal appears when an inspection or maintenance input is set in the
bay unit and a position indicator on an isolator or circuit-breaker
connected to the bay unit is forced into a particular status.
Forcing of an isolator or circuit-breaker in this context means: The item of
switchgear changes either from CLOSED to OPEN or from OPEN to
CLOSED.
21820_Alarm Signals an alarm situation in a bay unit: if an auxiliary supply fault is being
signaled or if a bay unit diagnostic system has detected an analogue
signal processing error.
