Description of Typical Setting file.

1.5.1.1 Relay Binary Inputs
Reference Connection
(e.g. I1 =Binary
Input 1)
I1 Energised from Solkor R/Rf
module contact.
I2 Energised from Guard
Override panel switch
(latched)
I3 Backup OC/EF Inhibit from a
panel switch (latched)
1.5.1.2 User Logic
Reference Setting
V1 50-1 or 50G-1 Guard elements
operated
E1 I1.!V1.!I2
E2 (I1.V1)+(I1.I2)
1.5.1.3 Relay Binary Outputs
Reference Setting
(e.g. O1 =Binary
Output 1)
O1 Protection Healthy
O2 Guard Relay Operated
(50-1 & 50G-1) & also
Guard Override
O3 87L Solkor operated
O4 Backup Overcurrent,
Earth Fault & E2
(=87L+Guard or
87L+Guard Override))
O5 E1 (=87L without
Guard)

Description
This triggers indication and a waveform record regardless of
the Guard relay/Trip.(A separate contact is wired externally via
a Guard contact for the trip circuit.)
The switch must also short the external guard contact to allow
removal/switch off of relay DC
Mapped as an inhibit on 51-2
Description
This is used to generate the Trip indication for 87L+Guard or
87L+ Guard Override
87L without Guard when Guard Override is not raised
Used to indicate a possible pilot open circuit, (Low level faults
below the guard setting may cause nuisance indications)
Indication of trip condition, (87L and Guard operation) or (87L
when Guard Override is raised).
This is an indication of trip condition, it is used to start
Waveform Recorder and Fault Record. It is also operates
the Trip output contact used by Backup OC/EF although it
is expected that the main trip will be direct from the Solkor
R/Rf module output contactor via a Guard contact/guard
override switch connected externally
Description
This is the main Guard contact for the trip circuit
This is for alarm/test only
This is the trip output which starts a Fault Record
This gives an alarm that the Solkor has tripped without the Guard
This could indicate pilot open circuit
(note that a fault occurs below the Guard setting but above the Rf
setting will create an alarm)
