• fully configured for the total available number of bays in
each REB670 variant
• facility to take any bay out of service via the local HMI or
externally via binary input
• facility to block any of the two zones via the local HMI or
externally via binary input
• facility to block all bay trips via the local HMI or externally
via binary input, but leaving all other function in service
(that is BBP Zones, BFP and OCP where applicable)
• facility to externally initiate built-in disturbance recorder
• facility to connect external breaker failure backup trip
signal from every bay
• facility to connect external bay trip signal
Configuration X01
• This configuration includes just busbar protection for
simple stations layouts (that is One-and-a-half breaker,
Double Breaker or Single Breaker stations). Additionally
it can be used for double busbar-single breaker stations
where disconnector replica is done by using just b
auxiliary contact from every disconnector and/or circuit
breakers. As a consequence no disconnector/breaker
supervision will be available. It is as well possible to
adapt this configuration by the Signal Matrix tool to be
used as direct replacement of RED521 · 1.0 terminals.
This configuration is available for all five REB670 variants
(that is A20, A31, B20, B21 & B31). It shall be noted that
optional functions breaker failure protection CCRBRF,
end fault protection and overcurrent protection
PH4SPTOC can be ordered together with this
configuration, but they will not be pre-configured. Thus
these optional functions shall be configured by the end
user.
Configuration X02
• This configuration includes just busbar protection for
double busbar-single breaker stations, where Zone
Selection is done by using a and b auxiliary contacts
from every disconnector and/or circuit breaker. Thus full
disconnector/breaker supervision is available. This
configuration is available for only three REB670 variants
(that is A31, B21 and B31). It shall be noted that optional
functions breaker failure protection CCRBRF, end fault
protection and overcurrent protection PH4SPTOC can
be ordered together with this configuration, but they will
not be pre-configured. Thus these optional functions
shall be configured by the end user.
Configuration X03
• This configuration includes BBP with breaker failure
protection CCRBRF, end fault protection and overcurrent
protection PH4SPTOC for double busbar-single breaker
stations, where Zone Selection is done by using a and b
auxiliary contacts from every disconnectors and/or
circuit breakers. Thus full disconnector/breaker
supervision is available. This configuration is available for
only three REB670 variants (that is A31, B21 and B31).
