quantities. The current setting is specified as a multiple of the nominal current, and the default setting is 30%. The
default settings used here are suitable for most applications.
When the VTS input source is set to 'NPS I/V, Negative Phase Sequence components of voltage and current are
used. Note that the same settings used but are applied on the basis of a level equivalent to the residual quantities
and are the settings are therefore 3x the actual NPS values. This setting philosophy means that the default
settings of 20v and 0.3xIn are also suitable for most applications when NPS input source is selected.
VTS 3PV Level
VTS 3PLOV Delay
A status input defined as 3 Ph V Chk Enable, can be defined. This is energised whenever the voltage on the
system should be live. If is status input is energised, and the relay checks that the voltage is live. If it detects
voltage below the VTS 3PV Level, the 3 Ph V Chk Alarm output will operate.

2.5 Reylogic Config

Elements of functions that have had the logic configured in REYLOGIC are found in this menu.
SR Dropoff
The Distance signal received can be extended using this timer to provide a variable pulse length.
POR Current Rev Reset (0..60000)
This is the time for which tripping is inhibited following a current reversal when a Permissive Overreach is in use.
POR CB Echo Pulse
This is the duration for which the signal send is activated when a Signal Receive input is energised when the
circuit breaker is open when the POR scheme is in use.
SS Dropoff
The Distance send signal can be delayed using this timer to provide a variable pulse length.
Permissive Trip Time
This is used for the distance blocked overreach scheme (BOR). This is the time for which the relay will wait for a
blocking signal from the remote end before a carrier-aided trip is carried out.
Min AUX DC SOTF Dead Time
The logic requires that the circuit breakers must have been closed for a minimum time before the SOTF logic is
initiated. This minimum time is set here. This setting is used for DC SOTF driven be CB auxiliary contacts only.
AC SOTF Pickup Delay
The logic requires that the circuit breakers must have been closed for a minimum time before the SOTF logic is
initiated. This minimum time is set here.
DC SOTF Active Timer
This setting fixes the time for which DC SOTF will be enabled after starting from a manual close handle or CB
auxiliary contact.
VTS Alarm Delay
Specifies the time for which a VTS condition must be present on the system before a VTS alarm is raised. This is
set to avoid nuisance alarms.
VTS Latch PU Delay
This is the minimum time that the VT fail conditions must remain on the system before the VT alarm is operated. It
is usually set to 5000ms to avoid nuisance alarms.
