high to low transition, via the “Input Trigger” cell. The default trigger settings are that any
dedicated trip output contacts (e.g. relay 3) will trigger the recorder.
It is not possible to view the disturbance records locally via the LCD; they must be extracted
using suitable software such as MiCOM S1. This process is fully explained in SCADA
Communications (P341/EN SC).
4.11 Changing setting groups
The setting groups can be changed either via 2 DDB signals or via a menu selection
selection or via the hotkey menu. In the Configuration column if “Setting Group - select via
PSL” is selected then DDBs 629 (SG Select 1x) and 628 (SG Select x1), which are
dedicated for setting group selection, can be used to select the setting group as shown in the
table below. These DDB signals can be connected to opto inputs for local selection or
control inputs for remote selection of the setting groups. If “Setting Group - select via menu”
is selected then in the Configuration column the “Active Settings - Group1/2/3/4” can be used
to select the setting group.
The setting group can be changed via the hotkey menu providing “Setting Group select via
menu” is chosen.

0 0 1
1 0 2
0 1 3
1 1 4
Note: Setting groups comprise both Settings and Programmable Scheme
Logic. Each is independent per group - not shared as common. The
settings are generated in the Settings and Records application within
MiCOM S1, or can be applied directly from the relay front panel menu.
The programmable scheme logic can only be set using the PSL Editor
application within MiCOM S1, generating files with extension ".psl". It
is essential that where the installation needs application-specific PSL,
that the appropriate .psl file is downloaded (sent) to the relay, for each
and every setting group that will be used. If the user fails to download
the required .psl file to any setting group that may be brought into
service, then factory default PSL will still be resident. This may have
severe operational and safety consequences.
4.18 Any trip
The “Any Trip” DDB (DDB 626) has been made independent from Relay 3 in the version 32
software. In Previous versions of software the “Any Trip” signal was the operation of Relay
3. In the version 32 software DDB 626 is the “Any Trip” signal and any output contact used
for tripping can be connected to the “Any Trip” DDB leaving Relay 3 to be freely assigned for
any function. The “Any Trip” signal affects the following functions:
Operates the Trip LED
Triggers CB condition maintenance counters
Used to measure the CB operating time
Triggers the circuit breaker failure logic
Used in the Fault recorder logic
